I'm having difficulty getting the exception from the OnDataBindingFailed event
the event fires as expected, but the eventArgs object doesn't have the methods
get_exception() - returns the deserialized response text.
get_responseText() - returns the response text from the service.
as described in this doc link
https://docs.telerik.com/devtools/aspnet-ajax/controls/listview/data-binding/client-side/api
The error that is showing on the console is
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource ... blah blah blah
what am in missing?

I am trying to get the values of the columns of the rad grid. I can get all the static values but not the value of the template column where the user would input values.

I have a Telerik Grid in which I have declared Radbutton which is populated in itemdatabound event. I have disabled it with condition from database.
But When ever the page index is Changed at the same item index the button is disabled.
Please kindly suggest a better way to do so.
Here is the code inside the ItemDataBound event
if (e.Item is GridDataItem)
{
GridDataItem dataItem = e.Item as GridDataItem;
if ((rddlLogLevel.SelectedValue).Contains("ERROR") == true)
{
DataSet ds = (DataSet)Session["LogErrors"];
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
if (ds.Tables[0].Rows[e.Item.ItemIndex]["PSRNumber"].ToString() == "" && ds.Tables[0].Rows[e.Item.ItemIndex]["LeretaPSRLogID"].ToString() == "")
{ (dataItem["Action"].FindControl("rbtnCreatePSR") as RadButton).Enabled = true; }
else if (ds.Tables[0].Rows[e.Item.ItemIndex]["PSRNumber"].ToString() == "" && ds.Tables[0].Rows[e.Item.ItemIndex]["LeretaPSRLogID"].ToString() != "")
{ (dataItem["Action"].FindControl("rbtnCreatePSR") as RadButton).Enabled = false; }
else { (dataItem["Action"].FindControl("hylnk_PSR") as HyperLink).Visible = true; }
}
}
else { (dataItem["Action"].FindControl("rbtnCreatePSR") as RadButton).Enabled = false; }

I have a RadGrids that resize the height with the window. That has been working for several years in 6 different grids with almost identical code. In one of these grids all of sudden, on a new page/refresh the grid rows go to about 10 pixels high. If I resize the window it all goes back to normal. I have tried many different things to get open a new page for the grid to be 100% in the panel it is in. I am lost, I did not change anything, the ASP.NET Ajax drop was working fine and suddenly this problem appears with one of six grids. Programming is not supposed to work this way.
<script type="text/javascript"> $(document).ready(function () { SetGridDiv(); }); window.onresize = function (event) { SetGridDiv(); } function SetGridDiv() { var height = $(window).height(); var gridDiv = document.getElementById("MainContent_GridDiv"); height = height - 100; height += "px"; gridDiv.style.height = height; }</script><div id="GridDiv" runat="server" > <asp:panel runat="server" ID="HomeGridPanel" CssClass="windowPercent" > <telerik:RadGrid runat="server" ID="OrganizationsGrid" OnItemCommand="Grid_ItemCommand"> <ClientSettings> <ClientEvents OnRowDblClick="RowDblClick" /> </ClientSettings> </telerik:RadGrid> </asp:panel></div>
And the C# .cs code.
RadGrid adminGrid = OrganizationsGrid; adminGrid.NeedDataSource += new GridNeedDataSourceEventHandler(AdminGrid_NeedDataSource); adminGrid.Skin = "Default"; adminGrid.AutoGenerateColumns = false; adminGrid.EnableViewState = false; adminGrid.GroupingEnabled = false; adminGrid.AllowPaging = true; adminGrid.PageSize = 500; adminGrid.Height = Unit.Percentage(100); adminGrid.EnableHeaderContextMenu = true; adminGrid.AllowSorting = true; adminGrid.AllowFilteringByColumn = true; adminGrid.AllowMultiRowSelection = false; adminGrid.AllowAutomaticDeletes = true; adminGrid.MasterTableView.HierarchyDefaultExpanded = true; adminGrid.ClientSettings.EnableRowHoverStyle = true; adminGrid.ClientSettings.Selecting.AllowRowSelect = true; adminGrid.ClientSettings.Selecting.EnableDragToSelectRows = true; adminGrid.ClientSettings.ReorderColumnsOnClient = true; adminGrid.ClientSettings.AllowColumnsReorder = true; adminGrid.ClientSettings.ColumnsReorderMethod = GridClientSettings.GridColumnsReorderMethod.Reorder; adminGrid.ClientSettings.Virtualization.EnableVirtualization = true; adminGrid.ClientSettings.Virtualization.InitiallyCachedItemsCount = 2000; adminGrid.ClientSettings.Scrolling.AllowScroll = true; adminGrid.ClientSettings.Scrolling.UseStaticHeaders = true; adminGrid.ClientSettings.Scrolling.ScrollHeight = Unit.Percentage(100); adminGrid.ClientSettings.Resizing.AllowColumnResize = true; adminGrid.PagerStyle.Mode = GridPagerMode.NextPrevNumericAndAdvanced; adminGrid.GroupingSettings.CaseSensitive = false; //Add columns to Grid GridBoundColumn boundColumn; boundColumn = new GridBoundColumn(); boundColumn.Display = false; boundColumn.DataField = OrganizationListData.FIELD_ID; boundColumn.HeaderText = OrganizationListData.FIELD_ID; boundColumn.ShowFilterIcon = false; adminGrid.MasterTableView.Columns.Add(boundColumn);The columns and rows are all done in server code.
This all just so strange. The grid rows appear correctly and then a flash later shrinks to half a row. Resize and all works fine.
I have tried delayed multiple resize SetGridDiv calls, no luck.
I have tried setting the grid height to 100%, the panel windowPercent class sets the height to 100% already.
I have tried setting a row count.
The Grid samples seem to do nothing to get grids with height. They use class demo-container and no-bg which are not defined in the sample code.
This is a MAJOR product disaster, an important grid starting out as a half row. If this cannot be fixed I will be forced to find other tools.

Hi, we have 404 page configured in webconfig: so that when a non-existent page like this https://www.ximnet.com.my/something or page with errors will go to a friendly 404 page.
But for https://www.ximnet.com.my/Telerik.Web.UI.WebResource.axd, it cannot redirect to 404 page.
How can we redirect the axd to our 404 page?
We need this because in Acunetix scanning, it will tag this page as showing "Application Error Message"
Thanks.

We are facing a performance problem, when using RadGrid in RadSpliiter.
We have a MasterPage with multiple RadSplitter which should resize with window. Here is the code:
The performance with only static content for this page is excellent.
Now we place a RadGrid in main Content (cphHauptInhalt).
The performance is now very very bad!
If the grid has only 100 items, it take about 4s to load, with 300 items it takes about 7s and with 700 items it takes 12s. Most of the time (round about 85%) the client works in javascript functions and the cpu is blocked with 100% load. Also if the mouse moves or the client window is resized.
I think, the performance is down because of the large DOM-Tree.
Is there a trick or anything to stop javascript calculating the whole DOM? Or is there another reason why it is so slow?

Currently, the RadComboBox displays a comma delimited list of checked items until all of the items are checked, at which point it displays "All items checked". Would it be possible to get it to continue displaying the comma delimited list instead of that message when all of the items are checked?
