I want to override route in ASP.NET Core 5
I tried this one but it is not working
var lastExistingRoute= routeBuilder.Routes.FirstOrDefault(x => ((Route)x).Name == "HomePage");
routeBuilder.Routes.Remove(lastExistingRoute);
routeBuilder.MapRoute("HomePage", "",
new { controller = "CustomPage", action = "Homepage", });
var lastDownloadRoute=routeBuilder.Routes.FirstOrDefault(x => ((Route)x).Name == "GetDownload");
routeBuilder.Routes.Remove(lastDownloadRoute);
routeBuilder.MapRoute("GetDownload", "download/getdownload/{guid}/{agree?}",
new { controller = "AzTechProduct", action = "GetPayed", });
Created same route with high different display order is worked for me
And good this is it not throwing any exception on inserting new route with the same name
public void RegisterRoutes(IEndpointRouteBuilder endpointRouteBuilder)
{
endpointRouteBuilder.MapControllerRoute("NewCheckout", "onepagecheckout",
new { controller = "NewCheckout", action = "OnePageCheckout" });
}
return string.Empty;
}
public int Priority
{
get
{
return 100;
}
}
}
Currently we are building a web application, desktop first, that needs device specific Razor Pages for specific pages. Those pages are really different from their Desktop version and it makes no sense to use responsiveness here.
We have tried to implement our own IViewLocationExpander and also tried to use the MvcDeviceDetector library (which is basically doing the same). Detection of the device type is no problem but for some reason the device specific page is not picked up and it is constantly falling back to the default Index.cshtml.
(edit: We're thinking about implementing something based on IPageConvention, IPageApplicationModelProvider or something ... ;-))
Index.mobile.cshtml
Index.cshtml
We have added the following code using the example of MvcDeviceDetector:
public static IMvcBuilder AddDeviceDetection(this IMvcBuilder builder)
{
builder.Services.AddDeviceSwitcher<UrlSwitcher>(
o => { },
d => {
d.Format = DeviceLocationExpanderFormat.Suffix;
d.MobileCode = "mobile";
d.TabletCode = "tablet";
}
);
return builder;
}
and are adding some route mapping
routes.MapDeviceSwitcher();
We expected to see Index.mobile.cshtml to be picked up when selecting a Phone Emulation in Chrome but that didnt happen.
edit Note:
we're using a combination of Razor Views/MVC (older sections) and Razor Pages (newer sections).
also not every page will have a mobile implementation. That's what would have a IViewLocationExpander solution so great.
edit 2
I think the solution would be the same as how you'd implement Culture specific Razor Pages (which is also unknown to us ;-)). Basic MVC supports Index.en-US.cshtml
Final Solution Below
If this is a Razor Pages application (as opposed to an MVC application) I don't think that the IViewLocationExpander interface is much use to you. As far as I know, it only works for partials, not routeable pages (i.e. those with an #page directive).
What you can do instead is to use Middleware to determine whether the request comes from a mobile device, and then change the file to be executed to one that ends with .mobile. Here's a very rough and ready implementation:
public class MobileDetectionMiddleware
{
private readonly RequestDelegate _next;
public async Task Invoke(HttpContext context)
{
if(context.Request.IsFromAMobileDevice())
{
context.Request.Path = $"{context.Request.Path}.mobile";
}
await _next.Invoke(context);
}
}
It's up to you how you want to implement the IsFromAMobileDevice method to determine the nature of the user agent. There's nothing stopping you using a third party library that can do the check reliably for you. Also, you will probably only want to change the path under certain conditions - such as where there is a device specific version of the requested page.
Register this in your Configure method early:
app.UseMiddleware<MobileDetectionMiddleware>();
I've finally found the way to do it convention based. I have implemented a IViewLocationExpander in order to tackle the device handling for basic Razor Views (including Layouts) and I've implemented IPageRouteModelConvention + IActionConstraint to handle devices for Razor Pages.
Note: this solution only seems to be working on ASP.NET Core 2.2 and up though. For some reason 2.1.x and below is clearing the constraints (tested with a breakpoint in a destructor) after they've been added (can probably be fixed).
Now I can have /Index.mobile.cshtml /Index.desktop.cshtml etc. in both MVC and Razor Pages.
Note: This solution can also be used to implement a language/culture specific Razor Pages (eg. /Index.en-US.cshtml /Index.nl-NL.cshtml)
public class PageDeviceConvention : IPageRouteModelConvention
{
private readonly IDeviceResolver _deviceResolver;
public PageDeviceConvention(IDeviceResolver deviceResolver)
{
_deviceResolver = deviceResolver;
}
public void Apply(PageRouteModel model)
{
var path = model.ViewEnginePath; // contains /Index.mobile
var lastSeparator = path.LastIndexOf('/');
var lastDot = path.LastIndexOf('.', path.Length - 1, path.Length - lastSeparator);
if (lastDot != -1)
{
var name = path.Substring(lastDot + 1);
if (Enum.TryParse<DeviceType>(name, true, out var deviceType))
{
var constraint = new DeviceConstraint(deviceType, _deviceResolver);
for (var i = model.Selectors.Count - 1; i >= 0; --i)
{
var selector = model.Selectors[i];
selector.ActionConstraints.Add(constraint);
var template = selector.AttributeRouteModel.Template;
var tplLastSeparator = template.LastIndexOf('/');
var tplLastDot = template.LastIndexOf('.', template.Length - 1, template.Length - Math.Max(tplLastSeparator, 0));
template = template.Substring(0, tplLastDot); // eg Index.mobile -> Index
selector.AttributeRouteModel.Template = template;
var fileName = template.Substring(tplLastSeparator + 1);
if ("Index".Equals(fileName, StringComparison.OrdinalIgnoreCase))
{
selector.AttributeRouteModel.SuppressLinkGeneration = true;
template = selector.AttributeRouteModel.Template.Substring(0, Math.Max(tplLastSeparator, 0));
model.Selectors.Add(new SelectorModel(selector) { AttributeRouteModel = { Template = template } });
}
}
}
}
}

I need to get the variable score from my other class and set it as a UserPrefs key. it doesnt seem to be setting as i have a GUI label ingame which shos "None" if there is no UserPrefs key "Highscore".
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.Threading;
public class Player : MonoBehaviour {
public Vector2 jumpForce = new Vector2(0, 300);
private Rigidbody2D rb2d;
Generator SwagScript;
GameObject generator;
// Use this for initialization
void Start () {
rb2d = gameObject.GetComponent<Rigidbody2D>();
generator = GameObject.FindGameObjectWithTag("Generator");
SwagScript = generator.GetComponent<Generator>();
}
// Update is called once per frame
void Update () {
if (Input.GetKeyUp("space"))
{
rb2d.velocity = Vector2.zero;
rb2d.AddForce(jumpForce);
}
Vector2 screenPosition = Camera.main.WorldToScreenPoint(transform.position);
if (screenPosition.y > Screen.height || screenPosition.y < 0)
{
Die();
}
}
void OnCollisionEnter2D(Collision2D other)
{
Die();
}
void Die()
{
if (PlayerPrefs.HasKey("HighScore"))
{
if (PlayerPrefs.GetInt("Highscore") < SwagScript.score)
{
PlayerPrefs.SetInt("HighScore", SwagScript.score);
}
else
{
PlayerPrefs.SetInt("HighScore", SwagScript.score);
}
}
Application.LoadLevel(Application.loadedLevel);
}
}
Unless you're creating the Highscore playerpref somewhere else, the Die() method won't never create it, since the if (PlayerPrefs.HasKey("HighScore")) will always return false.
Just remove that if.
When my Silverlight page loads, I want to set focus on a control. Simple problem with a not-so-obvious solution.
I tried the following with no luck. The page loads but my control does not have focus.
public MainPage()
{
InitializeComponent();
if( !DesignerProperties.IsInDesignTool )
{
// some init code goes here...
this.Loaded += ( s, e ) =>
{
this.InitFocus();
};
}
}
private void InitFocus()
{
this.PropNumTextBox.Focus();
}
The solution is to use System.Windows.Browser.HtmlPage.Plugin.Focus(). When I call this prior to calling Focus on my initial control, it works as expected. The correct code looks as follows:
public MainPage()
{
InitializeComponent();
if( !DesignerProperties.IsInDesignTool )
{
// init code here...
this.Loaded += ( s, e ) =>
{
this.InitFocus();
};
}
}
private void InitFocus()
{
// this call is necessary to initialize focus on page load
System.Windows.Browser.HtmlPage.Plugin.Focus();
this.PropNumTextBox.Focus();
}
Do anyone have good ideas of how to modify the toolbar for the WinForms version of the ReportViewer Toolbar?
That is, I want to remove some buttons and varius, but it looks like the solution is to create a brand new toolbar instead of modifying the one that is there.
Like, I had to remove export to excel, and did it this way:
// Disable excel export
foreach (RenderingExtension extension in lr.ListRenderingExtensions()) {
if (extension.Name == "Excel") {
//extension.Visible = false; // Property is readonly...
FieldInfo fi = extension.GetType().GetField("m_isVisible", BindingFlags.Instance | BindingFlags.NonPublic);
fi.SetValue(extension, false);
}
}
A bit trickysh if you ask me..
For removing toolbarbuttons, an possible way was to iterate through the Control array inside the ReportViewer and change the Visible property for the buttons to hide, but it gets reset all the time, so it is not an good way..
WHEN do MS come with an new version btw?
Yeap. You can do that in a little tricky way.
I had a task to add more scale factors to zoom report. I did it this way:
private readonly string[] ZOOM_VALUES = { "25%", "50%", "75%", "100%", "110%", "120%", "125%", "130%", "140%", "150%", "175%", "200%", "300%", "400%", "500%" };
private readonly int DEFAULT_ZOOM = 3;
//--
public ucReportViewer()
{
InitializeComponent();
this.reportViewer1.ProcessingMode = ProcessingMode.Local;
setScaleFactor(ZOOM_VALUES[DEFAULT_ZOOM]);
Control[] tb = reportViewer1.Controls.Find("ReportToolBar", true);
ToolStrip ts;
if (tb != null && tb.Length > 0 && tb[0].Controls.Count > 0 && (ts = tb[0].Controls[0] as ToolStrip) != null)
{
//here we go if our trick works (tested at .NET Framework 2.0.50727 SP1)
ToolStripComboBox tscb = new ToolStripComboBox();
tscb.DropDownStyle = ComboBoxStyle.DropDownList;
tscb.Items.AddRange(ZOOM_VALUES);
tscb.SelectedIndex = 3; //100%
tscb.SelectedIndexChanged += new EventHandler(toolStripZoomPercent_Click);
ts.Items.Add(tscb);
}
else
{
//if there is some problems - just use context menu
ContextMenuStrip cmZoomMenu = new ContextMenuStrip();
for (int i = 0; i < ZOOM_VALUES.Length; i++)
{
ToolStripMenuItem tsmi = new ToolStripMenuItem(ZOOM_VALUES[i]);
tsmi.Checked = (i == DEFAULT_ZOOM);
//tsmi.Tag = (IntPtr)cmZoomMenu;
tsmi.Click += new EventHandler(toolStripZoomPercent_Click);
cmZoomMenu.Items.Add(tsmi);
}
reportViewer1.ContextMenuStrip = cmZoomMenu;
}
}
private bool setScaleFactor(string value)
{
try
{
int percent = Convert.ToInt32(value.TrimEnd('%'));
reportViewer1.ZoomMode = ZoomMode.Percent;
reportViewer1.ZoomPercent = percent;
return true;
}
catch
{
return false;
}
}
private void toolStripZoomPercent_Click(object sender, EventArgs e)
{
ToolStripMenuItem tsmi = sender as ToolStripMenuItem;
ToolStripComboBox tscb = sender as ToolStripComboBox;
if (tscb != null && tscb.SelectedIndex > -1)
{
setScaleFactor(tscb.Items[tscb.SelectedIndex].ToString());
}
else if (tsmi != null)
{
if (setScaleFactor(tsmi.Text))
{
foreach (ToolStripItem tsi in tsmi.Owner.Items)
{
ToolStripMenuItem item = tsi as ToolStripMenuItem;
if (item != null && item.Checked)
{
item.Checked = false;
}
}
tsmi.Checked = true;
}
else
{
tsmi.Checked = false;
}
}
}
Get the toolbar from ReportViewer control:
ToolStrip toolStrip = (ToolStrip)reportViewer.Controls.Find("toolStrip1", true)[0]
Add new items:
toolStrip.Items.Add(...)
There are a lot of properties to set which buttons would you like to see.
For example ShowBackButton, ShowExportButton, ShowFindControls, and so on. Check them in the help, all starts with "Show".
But you are right, you cannot add new buttons. You have to create your own toolbar in order to do this.
What do you mean about new version? There is already a 2008 SP1 version of it.
Another way would be to manipulate the generated HTML at runtime via javascript. It's not very elegant, but it does give you full control over the generated HTML.
For VS2013 web ReportViewer V11 (indicated as rv), the code below adds a button.
private void AddPrintBtn()
{
foreach (Control c in rv.Controls)
{
foreach (Control c1 in c.Controls)
{
foreach (Control c2 in c1.Controls)
{
foreach (Control c3 in c2.Controls)
{
if (c3.ToString() == "Microsoft.Reporting.WebForms.ToolbarControl")
{
foreach (Control c4 in c3.Controls)
{
if (c4.ToString() == "Microsoft.Reporting.WebForms.PageNavigationGroup")
{
var btn = new Button();
btn.Text = "Criteria";
btn.ID = "btnFlip";
btn.OnClientClick = "$('#pnl').toggle();";
c4.Controls.Add(btn);
return;
}
}
}
}
}
}
}
}
I had this question for al ong time I I found the answer after a long tie and the main source of kowledge I used was this webpega: I'd like to thank you all guys adding the code that allowed me to do it and a picture with the result.
Instead of using the ReportViewer Class, you need to create a new classs, in my case, I named it ReportViewerPlus and it goes like this:
using Microsoft.Reporting.WinForms;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace X
{
class ReportViewerPlus : ReportViewer
{
private Button boton { get; set; }
public ReportViewerPlus(Button but) {
this.boton = but;
testc(this.Controls[0]);
}
public ReportViewerPlus()
{
}
private void testc(Control item){
if(item is ToolStrip)
{
ToolStripItemCollection tsic = ((ToolStrip)item).Items;
tsic.Insert(0, new ToolStripControlHost(boton));
return;
}
for (int i = 0; i < item.Controls.Count; i++)
{
testc(item.Controls[i]);
}
}
}
}
You have to add the button directly in the constructor of the class and you can configure the button in your designer.
Here's a pic of the result, not perfect, but enough to go(safe link I swear, but I can't post my own pics, don't have enough reputation).
http://prntscr.com/5lfssj
If you look carefully in the code of the class, you'd see more or less how it works and you could make your changes and make it possible to establish it in other site of the toolbar.
Thank you so much for helping me in the past, I hope this helps lots of people!
Generally you are suppose to create your own toolbar if you want to modify it. Your solution for removing buttons will probably work if that is all you need to do, but if you want to add your own you should probably just bite the bullet and build a replacement.
You may modify reportviewer controls by CustomizeReportToolStrip method.
this example remove Page Setup Button, Page Layout Button in WinForm
public CustOrderReportForm() {
InitializeComponent();
CustomizeReport(this.reportViewer1);
}
private void CustomizeReport(Control reportControl, int recurCount = 0) {
Console.WriteLine("".PadLeft(recurCount + 1, '.') + reportControl.GetType() + ":" + reportControl.Name);
if (reportControl is Button) {
CustomizeReportButton((Button)reportControl, recurCount);
}
else if (reportControl is ToolStrip) {
CustomizeReportToolStrip((ToolStrip)reportControl, recurCount);
}
foreach (Control childControl in reportControl.Controls) {
CustomizeReport(childControl, recurCount + 1);
}
}
//-------------------------------------------------------------
void CustomizeReportToolStrip(ToolStrip c, int recurCount) {
List<ToolStripItem> customized = new List<ToolStripItem>();
foreach (ToolStripItem i in c.Items) {
if (CustomizeReportToolStripItem(i, recurCount + 1)) {
customized.Add(i);
}
}
foreach (var i in customized) c.Items.Remove(i);
}
//-------------------------------------------------------------
void CustomizeReportButton(Button button, int recurCount) {
}
//-------------------------------------------------------------
bool CustomizeReportToolStripItem(ToolStripItem i, int recurCount) {
Console.WriteLine("".PadLeft(recurCount + 1, '.') + i.GetType() + ":" + i.Name);
if (i.Name == "pageSetup") {
return true;
}
else if (i.Name == "printPreview") {
return true;
}
return false; ;
}
