Hello

I have several RadGrids with custom css applied to the columns.  Everything works as intended.  However, when a column is sorted, telerik applied the .rgSorted css and this completely defeats the purpose of the gird (in our application).  What is the procedure to DISABLE or DELETE the .rgSorted css, as this particular class will never be needed or used. 

Note: any css class definition with !important cannot be used in this context.

Thank you

I have encountered a niche issue I'm trying to solve. I have a grid with EnableViewState set to false. Based on this, the control state within the grid is used to manage things like sort expressions.

My issue is simply this:

1. Page load
2. Programmatically add columns to a grid
3. On the UI, sort on a column, and its name for example is 'My Column', this becomes 'My Column ASC'
4. On our app are objects in which its name we can add as a column to the same grid
5. Somewhere in our app I rename the object's name to something else like 'My New Column' - note the sort expression is still 'My Column ASC'
6. Back to the grid, I cause a postback (e.g., rebind) or reorder a column, or sort, etc.
7. The columns need to be re-added (I've covered a case to exclude the column with the old name)
8. Before columns are added again, I manually clear sort expressions on the grid
9. While debugging, I found that in the ColumnCreated event, the grid sort expressions restore to what they were before the postback, and I see 'My Column ASC' - I find that whenever adding a SortExpression referencing a non-existing column, the program always breaks

I debugged against a few events of the grid and found that in ColumnCreated (after NeedDataSource) the grid restored its sort expressions from what I presume is the control state. So, this was between NeedDataSource and ColumnCreated.

When exactly did the sort expressions get restored, and is there an event I can listen to?

I'm experiencing an issue where the page becomes unresponsive for a long time whenever any Telerik control (such as refresh or loader) is triggered. The page keeps loading indefinitely, causing significant delays, and eventually, the page becomes unresponsive.

Additionally, the following error appears in the browser console:

Uncaught Sys.WebForms.PageRequestManagerTimeoutException: Sys.WebForms.PageRequestManagerTimeoutException: The server request timed out.
at Error.create (https://test.plc.com/GS/Telerik.Web.UI.WebResource.axd?...:6:2736)
at Sys.WebForms.PageRequestManager._createPageRequestManagerTimeoutError (https://wpinhouse.knpc.com/GPCS/Telerik.Web.UI.WebResource.axd?...:15:11219)
at Sys.WebForms.PageRequestManager._onFormSubmitCompleted (https://wpinhouse.knpc.com/GPCS/Telerik.Web.UI.WebResource.axd?...:15:11219)

The issue arises when interacting with Telerik controls that trigger a page request, causing the page to hang and ultimately become unresponsive.

issue started from Feb 17 2025

• I have full trust enabled.
• I have both RadAjax.Net2 and RadGrid.Net2 added as SafeControls (as is my UserControl).
• The folders (hosting the dlls, user control and RadControls files) all have read & execute access enabled for the Thread Account.
• The site uses forms based authentication.

With the R2 2022 release Telerik added this support via a skin (BlackMetroTouch) but it seems it is limited to a server side setting and can't be done via client side? In particular I'm looking to do this for the RadGrid and change it via a user toggle and not have to make a post back to reload the page. Please let me know if there exists a way to do it at client-side.

Thanks,
Gerry

Afternoon,

I am using a RadGrid with Batch Editing.  Under a couple of conditions I want to be able to stop a cell from being edited.

I've followed another example using the OnBatchEditOpening client event:

        function onBatchEditOpening(sender, args) {
            args.get_tableView().get_dataItems();
            var cell = args.get_cell();
            var cellValue = cell.innerText;
            var columnUniqueName = args.get_columnUniqueName();
            var row = args.get_row();
            var item = row.control;
            var itemIndex = item.get_itemIndex();

            if (itemIndex > -1) { // if itemIndex is -1 it means this is a new row
                if ((columnUniqueName === "Process_type" && cellValue === "L") ||
                    (columnUniqueName === "Process_order" && cellValue === "1")) {
                    args.set_cancel(true);
                }
            }

It just so happens that when the process type is L and process order is 1 will occur in the same row, so all other rows should remain unaffected.

It works fine - I click in the row with 1 and L, and the process order and process type cells are not editable. However, when I then click on a field in another row I get this error:

This only occurs when I've clicked in the row with the non-editable cells first.

Any ideas on how to clear this?

Kind regards,

Richard

Hi

I have a Telerik rad grid which populates data, one of the columns is date and is in format of DD-MMM-YY.

when I click on the header of the column to sort, it doesnt sort it correct in ascending date or descending order. Im assuming its because of the format as the month is a string.

Can anyone advise how to get it to sort correctly please?

Thanks
