var selected = {};
function dgGrid_RowSelected(sender, args) {
    var cpayID = args.getDataKeyValue("ID");
    if (!selected[cpayID]) {
        selected[cpayID] = true;
    }
}
 
function dgGrid_RowDeselected(sender, args) {
    var cpayID = args.getDataKeyValue("ID");
    if (selected[cpayID]) {
        selected[cpayID] = false;
    }
}
 
function dgGrid_RowCreated(sender, args) {
    var cpayID = args.getDataKeyValue("ID");
    if (selected[cpayID]) {
        args.get_gridDataItem().set_selected(true);
    }
}
 
function dgGrid_Created(sender, eventArgs) {
    var masterTable = sender.get_masterTableView(),
        headerCheckBox = $telerik.$(masterTable.HeaderRow).find(":checkbox")[0];
 
    if (headerCheckBox) {
        headerCheckBox.checked = masterTable.get_selectedItems().length == masterTable.get_pageSize();
    }
}
I am using the above code to update the selections made across pages.   When I turn on sorting, and check just the first row, and then sort, when the grid refreshes, the single row is checked, but also the select all checkbox at the top is checked.

Hello Peter,

Thank you for contacting us.

The corresponding help article has been recently updated. Please use the changed GridCreated function and let me know about the result:

Looking forward to your reply.

I got this error:
Uncaught TypeError: Property `$` of object [object Object] is not a function

From this line:
var headerCheckBox = $(selectColumn.get_element()).find("[type=checkbox]")[0];

I thought the line should be:
var headerCheckBox = $telerik.$(selectColumn.get_element()).find("[type=checkbox]")[0];

But I get this error:

Uncaught TypeError: Cannot call method `get_element` of null


Your code assumes JQuery is present with the page, not just in the telerik controls.

I tried using this line with my original Created function, but it had no effect on the original issue.
headerCheckBox.checked = masterTable.get_selectedItems().length == masterTable.get_dataItems().length;

Hi Peter,

You can refer to the following code library to verify that the approach works as expected. Can you please run the sample provided in the link and instruct us the exact steps to reproduce the issue?

The checkboxes themselves work fine.    Again here is my problem:

1. Multi items showing in a grid.
2. Select the checkbox on the first row at least.
3. Click a column header to sort the grid.
4. The "Select All" checkbox is now checked.

Hi Peter,

Can you please verify that you have replaced SelectColumnID from the function with the unique name of the ClientSelectColumn?

I made the changes as demonstrated in the example and I got the same results when following these steps:

Hi Peter,

I have created a sample RadGrid web site to test the described behavior. On my side the sorting and selection preserving is working correctly upon following the exact provided steps. Can you please run the attached application and verify that it works as expected from your end, too?

The database 'C:\INETPUB\WWWROOT\TESTINGSITES\TELERIKSUPPORT\GRIDCHECKBOXESSORT\APP_DATA\NORTHWIND.MDF' cannot be opened because it is version 655. This server supports version 612 and earlier. A downgrade path is not supported.
Could not open new database 'C:\INETPUB\WWWROOT\TESTINGSITES\TELERIKSUPPORT\GRIDCHECKBOXESSORT\APP_DATA\NORTHWIND.MDF'. CREATE DATABASE is aborted.

You are running a newer version of SQLExpress, than I have.

I applied the updated javascript again to my page, and I must have missed something before.

Now it works as expected.
