How to Save the search inputs and page number(state Save) of all of the tables in CoreUI data table
Eg. I search for a postcode, and go onto page 2. When I go back to the table after going onto the customers page, it should take me back to exactly where I left off, which is the search inputs and the page.
First Picture shows when I click on page No. 3 and move to another page or home page and then come back to customers it should return back to page No 3 not page No 1
Use Datatables as reference.
This is how it works on the CRM which uses Datatables JS plugin:
https://gyazo.com/13152d149f26792a87c9a8e38b0159ab
data: () => {
return {
pageSizes: [10, 50, 100],
items: store,
fields: ['company_name', 'name', 'postal_code', 'phone1', 'phone2', 'email', 'created_at'],
currentPage: 1,
perPage: true,
stateSave: true,
totalRows: 0,
you: null,
message: '',
showMessage: false,
dismissSecs: 7,
dismissCountDown: 0,
showDismissibleAlert: false,
customerModal: false
}
},

This is a weird one.
I'm using datatables v1.10.19 with jQuery 3.3.1 and Bootstrap 3.3.7
My datatables grid is configured to display 1000 records (but you can change it to 2500, 5000 and "all").
I've only got about 60 records in my database.
It is using Server-Side processing to retrieve data.
When the grid loads, the pager displays 5 buttons plus an ellipses (as if there is even more).
And even weirder, if I change the drop-down to display "all" records, it acts as I would expect i.e. the pager has 1 page button.
The payloads are pretty much identical:
{
"data": {
"draw": 8,
"recordsTotal": 86,
"recordsFiltered": 66,
"data": [rows of data here]
},
"outcome": {
"opResult": "Success",
"message": ""
}
}
When you click on page 2, it does successfully retrieve a payload with 0 rows.
But there shouldn't be a page 2 available on the pager.
The config object for the datatable looks like this:
eventsSvr.buildConfig = function (url) {
return {
"processing": true,
"serverSide": true,
//"paging": true,
"ajax": {
url: url,
type: ajax.requestPOST,
dataSrc: 'data.data' // the path in the JSON structure to the array which will be the rows.
},
"order": [[1, "asc"]],
"lengthMenu": [[1000, 2500, 5000, -1], [1000, 2500, 5000, "All"]],
"initComplete": function (settings, json) {
eventsSvr.searchTextSpan.text('Search').removeClass('search-is-on');
},
"columns": eventsSvr.grid.columns,
"columnDefs": eventsSvr.grid.columnDefs,
dom: 'ltp'
};
I do have a bunch of custom searches on the page, so I've had to write a lot of code like this:
$.fn.dataTable.ext.search.push(
function (settings, data, dataIndex) {
var picker3 = $(eventsSvr.datePickerInputs[0]).data(icapp.kendoKey);
var picker4 = $(eventsSvr.datePickerInputs[1]).data(icapp.kendoKey);
var rowStartDate = moment(data[3], icapp.date.momentParseFormat).toDate();
var rowEndDate = moment(data[4], icapp.date.momentParseFormat).toDate();
... etc.
}
);
But the odd thing is the different behavior as between "All" records vs 1000 records.
As described above, select "All" records works (resulting in just 1 page button), but none of the other paging sizes work (i.e. 1000, 2500, 5000). The data for the 1 page does return, but I get 5 page buttons and an ellipses.
Any ideas why this would be happening?
When using server-side processing mode DataTables expects draw, recordsTotal and recordsFiltered to be root-level elements. Consider changing your repsonse to the following and you can remove dataSrc option.
{
"draw": 8,
"recordsTotal": 86,
"recordsFiltered": 66,
"data": [rows of data here],
"outcome": {
"opResult": "Success",
"message": ""
}
}
Alternatively you can manipulate the response before passing it to DataTables using function supplied as value for dataSrc option, but I would recommend keep things according to expected format for more readable code.
I'm using a plugin to create a data table with single row select capability such that when I click anywhere in the row, it links to another page in my web app. I need help figuring out how to disable the select capability on the first column of every row. I've tried using css rules but either they do not work or they are applied to columns other than the first.
Table declaration:
var locationTable = $('#locationTable').DataTable({
dom: 'Brtip',
buttons: [
'excel'
],
select: {
style: 'single'
//selector: ':not(:first-child)'
//selector: ':not(td:nth-of-type(1))'
},
processing: true,
serverSide: true,
ajax: "/locationData",
length: 10,
ordering: false,
"lengthChange": false,
//sDom : '<"top">lrtip',
columns: [
{data: 'locationname'},
{data: 'address1'},
{data: 'address2'},
{data: 'city'},
{data: 'state'},
{data: 'zipcode'},
{data: 'phone'},
{data: 'fax'}
]
});
My attempt to configure selection on every column (of every row) except the first:
//locationTable.select.selector(':not(tr>td:nth-child(1))');
locationTable.select.selector('tr>td:nth-child(2)');
demo
Solution: Add a CSS rule for each column you wish to enable select capability. In the example below, I wish to have select capability on all columns except the first.
select: {
style: 'single',
selector: 'tr>td:nth-child(2), tr>td:nth-child(3), tr>td:nth-child(4), tr>td:nth-child(5), tr>td:nth-child(6), tr>td:nth-child(7), tr>td:nth-child(8), tr>td:nth-child(9)'
}
I want to have client side paging.
But for some reason, I only seem to get back the first page? Even though I know I have two pages worth of data (IE... I step through my code, and I definitely have two...)... What is more baffling is that my links to navigate through the pages never seem to be correct... For instance I would expect the following screen to say 1 of 2...
Also I would expect the bottom right hand side to say View 1-15 of 21?
My feeling is that I am doing something wrong in my data layer to give this pager it's info.
So It only returns the first page.
public static string JsonifyEnc(IEnumerable<TemplateModel> model, int popId, int page, int rows) {
TemplateModel variable = model.ToArray()[0];
ArrayList al = new ArrayList();
//foreach (PatientACOModel patMod in variable.Template) {
int i = 1;
int rowstart = (page * rows + 1) - rows;
int rowend = page * rows;
//Here is where I create the rows... nothing special here
var griddata = new {
total = variable.Template.Count % rows > 0 ? (variable.Template.Count / rows) + 1 : (variable.Template.Count / rows),
page = page,
records = al.Count,
rows = al.ToArray()
};
When I quick wath the total variable it says two?
This would be the first part of my json string that is returned...
{"total":2,"page":1,"records":15,"rows":
So it's there. Also, this is how I am building up my jqGrid...
$(document).ready(function () {
jQuery("#frTable").jqGrid ({
cmTemplate: { sortable: false },
caption: '#TempData["POPNAME"]' + ' Population',
datatype: 'json',
mtype: 'GET',
url: '/Encounters/GetAjaxPagedGridData/', //'Url.Action("GetAjaxPagedGridData", "Encounters", new { popId = TempData["POPULATIONID"] })',//
postData: { popId: '#TempData["POPULATIONID"]'},
pager: '#pager',
jsonReader: {repeatitems: false},
loadonce: true,
height: 'auto',
gridview: true,
viewrecords: true,
rowNum: 15,
shrinkToFit: false,
autowidth: true,
If you use loadonce: true on the client side you should change the server code so that it ignores page and rows options and returns all data. You should just sort the data corresponds to sidx and sord parameter (see sortname and sortorder in jqGrid). You don't need to fill total, page and records parts in the response.
If you use loadonce: true jqGrid load the data and save it in internal data and _index parameters. After that jqGrid change datatype option of jqGrid to "local". So all later sorting, filtering (searching) and paging of data will be done locally.
I have a enhancedgrid and used on two pages. When check box (component of data enhanced grid) is checked on page1, the equivalent row(s) on pg 2 are then ticked. My enhancedgrid code is
grid = new dojox.grid.EnhancedGrid({
loadingMessage:"Please wait",
store:newStore,
structure:layoutQL,
autoWidth:false,
autoHeight:true,
columnReordering:false,
rowsPerPage:3,
indirectSelection: true,
//noDataMessage:"No transactions have been processed for posting.",
//selectionMode:'single',
plugins: {
pagination: {
description: true,
sizeSwitch: false,
pageStepper: true,
gotoButton: true,
/*page step to be displayed*/
maxPageStep: 6,
/*position of the pagination bar*/
position: "bottom",
indirectSelection: true
},
filter : {
// Show the closeFilterbarButton at the filter bar
closeFilterbarButton: true,
// Set the maximum rule count to 5
ruleCount: 5,
// Set the name of the items
itemsName: "records"
}
}
I am using EnhancedDataGrid as in dojo framework. Any help will be appreciated.
Try "grid.selection.deselectAll()" when you move from one page to the next.
May I know if it is possible to put pictures or images into the rows of DataTables (http://datatables.net/) and how does one goes in doing it?
yes, simple way (Jquery Datatable)
<script>
$(document).ready(function () {
$('#example').dataTable({
"processing": true, // control the processing indicator.
"serverSide": true, // recommended to use serverSide when data is more than 10000 rows for performance reasons
"info": true, // control table information display field
"stateSave": true, //restore table state on page reload,
"lengthMenu": [[10, 20, 50, -1], [10, 20, 50, "All"]], // use the first inner array as the page length values and the second inner array as the displayed options
"ajax":{
"url": "#string.Format("{0}://{1}{2}", Request.Url.Scheme, Request.Url.Authority, Url.Content("~"))/Home/AjaxGetJsonData",
"type": "GET"
},
"columns": [
{ "data": "Name", "orderable" : true },
{ "data": "Age", "orderable": false },
{ "data": "DoB", "orderable": true },
{
"render": function (data, type, JsonResultRow, meta) {
return '<img src="Content/Images/'+JsonResultRow.ImageSrcDB+'">';
}
}
],
"order": [[0, "asc"]]
});
});
</script>
[edit: note that the following code and explanation uses a previous DataTables API (1.9 and below?); it translates easily into the current API (in most cases, just ditch the Hungarian notation ("fnRowCallback" just becomes "rowCallback" for example) but I have not done so yet. The backwards compatibility is still in place I believe, but you should look for the newer conventions where possible]
Original reply follows:
What Daniel says is true, but doesn't necessarily say how it's done. And there are many ways. Here are the main ones:
1) The data source (server or otherwise) provides a complete image tag as part of the data set. Don't forget to escape any characters that need escaping for valid JSON
2) The data source provides one or more fields with the information required. For example, a field called "image link" just has the Images/PictureName.png part. Then in fnRowCallback you use this data to create an image tag.
"fnRowCallback": function( nRow, aData, iDisplayIndex, iDisplayIndexFull ) {
var imgLink = aData['imageLink']; // if your JSON is 3D
// var imgLink = aData[4]; // where 4 is the zero-origin column for 2D
var imgTag = '<img src="' + imgLink + '"/>';
$('td:eq(4)', nRow).html(imgTag); // where 4 is the zero-origin visible column in the HTML
return nRow;
}
3) Similar to above, but instead of adding a whole tag, you just update a class that has the image as a background. You would do this for images that are repeated elements rather than one-off or unique pieces of data.
You mean an image inside a column of the table?
Yes, just place an html image tag
like this
<img src="Images/PictureName.png">
instead of putting data (some string) into a column just put the above html tag....
Asp.net core DataTables
The following code retrieve the image from a folder in WWWroot and the path in the DB field ImagePath
{
"data": "ImagePath",
"render": function (data) {
return '<img src="' + data + '" class="avatar" width="50" height="50"/>';
}
}
In case the Name of the picturefile is put together out of one or more informations in the table, like in my case:
src="/images/' + Nummer + Belegnummer + '.jpg"
you can make it that way:
var table = $('#Table').DataTable({
columnDefs: [
{
targets: 0,
render: getImg
}
]
});
function getImg(data, row, full) {
var Nummer = full[1];
var Belegnummer = full[4];
return '<img src="/images/' + Nummer + Belegnummer + '.jpg"/>';}
The picture is in the first column, so Targets = 0 and gets the Information from the same row.
It is necessary to add the parameters data and row.
It is not necessary to outsource it into a seperate function, here getImg, but it makes it easier to debug.
