It is possible to set the height and width of the QR Code in pixels?. Already set de DotSize in 0, but the result image always has 53x53px.

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.

And the C# .cs code.

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.

I have my RadPageView setup with ContentURL, but on come conditions i need to redirect to different URL.

Nothing i tried works.

Help please
