I have created a winform app connected to an access database as datasource ,
but now i have added a column in access database & now i have to provide the same field in winform for data entry purpose.
But now in my data source the new field is not visible even after refreshing .
any help in solving this.
The simplest way to do this is to open the dataset, right click on the relevant table adapter (MSdiesTableAdapter), choose Configure and then go through the wizard, adding the new column to the SELECT sql. When you finish the wizard the new column will appear in the datatable.
It won't have appeared in any databound grid etc - you'll also have to go to those grids and do an "Edit Columns" and "Add a New Column", choose "DataBound Column" and pick the new column. You can also, as a quick trick, remove the "DataMember" setting from the bindingsource the grid is bound to, then put it back
Microsoft never intended for DataSets and databases to be perfectly aligned; the dataset is your client side store of info and it may have more or fewer columns than the database, and have stuff it calculates itself locally, or relationships that are different to the database. This is why it needs manually adding and working through
I am using Visual Studio 2013, Express version. I need to create a windows application that will allow users to generate reports. So I downloaded the ReportViewer 2012 RT and successfully added the ReportViewer dll to VS. So now I have a ReportViewer component in my toolbox I can add to a form.
Having never used ReportViewer before, I'm not sure where to go from here. I did find this page about how to add printable reports: http://msdn.microsoft.com/en-us/library/ms233804.aspx
The thing is, it gives these steps: 1) Drag a ReportViewer control from the Data tab of the Toolbox onto your form. 2) On the Project menu, choose Add New Item. In the Add New Item dialog box, select the Report icon and click Add. 3) The Report Designer opens in the development environment, and a report (.rdlc) file is added to the project.
After completing step 1 I do not see 'Report' in the list of items I can add. I do not see any other 'Report' components listed in the toolbox, either.
Does anyone know what I am missing?
I did a lot of searching found discussions about getting the ReportViewer in the first place that then stop there, or about using Report Builder. Based on my understanding of Report Builder, though, that is a SQL Server component and is for use in reporting on SQL server data...the reports in my application are to be based on local data (internal arrays), not SQL related at all. So I should just need the ReportViewer, right?
Thank you very much!
Crystal Reports offers an easy way to display repots:
Report rpt = new Report()
for (int i = 0; i < ds_consultsql.Tables[0].Rows.Count; i++)
{
ds_tableintheproject.Tables["table"].Rows.Add
(
new object[]
{
ds_info.Tables[0].Rows[i]["camp1"].ToString(),
ds_info.Tables[0].Rows[i]["camp2"].ToString(),
ds_info.Tables[0].Rows[i]["camp3"].ToString(),
ds_info.Tables[0].Rows[i]["campx"].ToString()
}
);
}
rpt.SetDataSource(ds_datos); reportesVW.ReportSource = rpt;
reportesVW.DataBind();
you just desing the report add your data from a datatable create in the proyect
I am doing a project using vb.net and sql server. I want to know how to create crystal report dynamically,i.e, when the user press the "Create report" button a form has to display where he can drag and drop the fields whichever he wants to display and save the report for future use
is not clear, you want a crystal report designer like the one in visual studio?
if so, you can check http://www.brothersoft.com/crystal-reports-download-79905.html
if not explain better.
How to I assign dataset to the existing report?
I went a little bit other way around then you usually do it - first build RDLC and then got my dataset done, however now I'm clueless how to assign that dataset to my report. In properties window whatever I select Body, Report or Tablix - I can't find anything that would allow me to choose dataset.
There was this screen (wizard) with drop-down that allowed you to pick dataset, but in no way I can find it. Anyone can help how to trigger it again? Or help me to assign my dataset to report in any other way?
You need to open the Report Data properties Window.
With an RDLC report open press the Ctrl+Alt+D or select the menu View then ReportData
There you find the DataSet node where, a right click, opens the Add New Dataset wizard
On my RDLC page, the "Report Data" window shows a custom dataset that it pulls fields from to display. I've modified this DataSet with some additional tables. However, these tables aren't shown and therefore I'm unable to select them for use in expressions (in the Expression window, under Datasets, there are only the tables that were originally there, not the additional tables I've added).
Refreshing the data source doesn't do anything, and if I right-click on it and select "New Dataset", I'm unable to select the parent data source (it doesn't appear in the drop down list). What I mean is, if the data source is called "MyDataSet", and under that are other DataSets, if I right-click and go to "Add Dataset", it brings up the dialog box but "MyDataSet" is not in the list of available Data sources, even though I'm specifically saying I want to add a datatable to that data source. The other, existing, datatables list it under the data source, but new ones do not.
How do I refresh the data source so I can access these new tables in my report?
This is an old question, but I was having this problem too and I'll mention my answer for future googlers.
In the Report Data Window (which automatically appears for me when I am editing a .rdlc file), I had to Refresh my Dataset (same name as the DataSetName in the Tablix in my .rdlc Report), and then that updated the XML of the .rdlc file. The new fields are then available to me.
I have the same problem with Visual Studio 2010 Premium. You must do this step:
Re-build the project that contain your Business Object
Restart Visual Studio
Refresh your DataSet (Report Data --> Right click on DataSet --> Refresh).
I managed to get this working (for SSRS in C# using a Dataset that points to a Stored Procedure) by:
hitting Shift+Alt+D (which opens the "Data Sources" window)
In Data Sources, select/click the table you want to update
At the top of the window there are icons (I'm using VS2012). The 2nd from the right is "Configure Data Source" - click it and it will open a new wizard window that will appear to be refreshing everything.
UN-check the column that is no longer applicable and/or check the new column (if the values aren't already checked/unchecked).
Go back to your "Report Data" window (Ctrl+Alt+D) and right-click on your Dataset and then click "Refresh".
All the columns should be updated at that point.
Have you tried rebuilding your project? I had to do this after changing any business object.
I had this issue for hours on VS-2008. Tried everything and at the end what worked was just to close and open it VS again.
I can confirm that just closing the solution and reopening it, with later refreshing the DataSet from Report Data window worked for me.
Seems like there is no need to restart VS.
I got the same issue in visual studio 2012. I solved it, here is the steps,
Press Ctrl + Q and type Report Data (If No Report Data window available)
Expand Data Source node to find the data set (I have used Data Set)
Right click on the Data set and select Refresh (Simply refresh the data source)
Delete the dataset and again add it with ur query or usp...
If you are using a database source the likely culprit is that you didn't create the query with select *. Without the * the query will always be static and new fields won't appear. HTH
For visual studio 2010
Open Your Data Set (.xsd file)
Right click on data set click on configure
Click on Next Next than finish
On your dataset click refresh than Changes willbe display.
Sounds like same issue is happening on VS2019. I could resolve the issue by only restarting Visual Studio, nothing else worked!
This is the only solution worked for me.
After updating the DataSource properly, open the .rdlc file in NotePad and add the newly added Field manually. Then it will be available to use in the report.
Had the same in VS2019 using an object datasource, right click and refresh on the dataset in the Report Data window had no effect until I changed the build configuration from x64 to Any CPU, then it worked as expected. Once it updated changed the build back and all was well - not at all flakey!
As ChanthJ said -
It is the only solution worked for me.
After updating the DataSource properly, open the .rdlc file in NotePad and add the newly added Field manually. Then it will be available to use in the report.
steps
Assuming you Data source is fed by stored procedures, the following worked for me (On Visual Studio 2017): -
Make the necessary changes in the source stored procedure in the Database(new Field Names etc.).
Double click the .XSD file from the Solution Explorer to open it
Delete the associated Data Table / Table Adapter.
Add the Table Adapter back into the .XSD file (the changes will be reflected)
Save and close the .XSD
Open the .rdlc report designer.
Press "ctrl+Alt+D" or Click View > Report Data.
Expand the Data Sources node.
Right Click the Data Source.
Select "Refresh".
Expand the Datasets node.
Right Click the Data Source.
Select "Refresh"
The changes will now reflect and be available for selection on the .rdlc
report designer
