When selecting a full table, by a standard, we get text selection, but we get the table selected (we can copy/paste the table)

Ive seen on docs you can change cell selection type to MultiCell, then you can shift+click and select cells, and its pretty much the same as the above however the visual selection is slightly different. In this case, however you cannot select texts manually like before.

I know you can change this selection type during runtime, but only in the backend is that right ?

What would be a good aproach to solve this problem ? Only do cell selection when shift is pressed, else do a normal selection.

Would apreciate any help !!

Best regards to Telerikers :)

Hello

I get sometimes a runtime error in production:

Message: Object reference not set to an instance of an object.
StackTrace:    at Telerik.Web.UI.RadEditor.<get_Text>b__b(Match m)

The error does not occur every time. My guess: the more data is processed, the more likely the w3wp.exe crashes, or more specific, the special export thread crashes.
I can not reproduce the error in the development environment.

Creation of the error:
The user wants to export data. The web server starts a separate thread for writing datas into an excel file (via MemoryStream). Codesnippet from the export method:

Loop, which calls the writeEXTFlat() methods multiple times

{
// static method writeEXTFlat()
  ... some code ...

  Line 11826:  Telerik.Web.UI.RadEditor re = new Telerik.Web.UI.RadEditor();

  ... more code without touching RadEditor ...

  foreach (int i =0; x < exportRecs; i++)
  {

     ... more code without touching RadEditor ...

     re.Content = strExportDataWithHTML;
     string strToExport = re.Text;

     ... more code without touching RadEditor ...
  }

}

My question : Any idea why this error can happen? It makes totaly no sense to me. strExportDataWithHTML is always at least an empty string.

TIA

Hello,

I followed this example to create a column chart: https://docs.telerik.com/devtools/aspnet-ajax/controls/htmlchart/chart-types/column-chart

Now I only want one column per serie, how can I archieve that?

Thanks.

I am trying to apply the modal setting for advanced insert, and it pops up, but with no background, see attached image.

My code for the template is:

I have a page with various controls. When I click a radio button, it clears ONLY the datetimepicker fields.  I tried both ASP.Net and Telerik radio buttons and both have the same effect. 

radio button:

<asp:RadioButton runat="server" Text ="<span style='font-size: 14px'>Repair and use</span>" TabIndex="115" ID="rbRepair" AutoPostBack="true" GroupName="rbGeneral" />

The radio button code behind:

txtRequestOther.Visible = False

datetimepicker:

<telerik:RadDateTimePicker ID="dtRequestDate" runat="server" Width="190px" Culture="en-US" TabIndex="40" Enabled="False">
<TimeView ID="TimeView2" runat="server" CellSpacing="-1"></TimeView>
<TimePopupButton CssClass="rcTimePopup rcDisabled" HoverImageUrl="" ImageUrl="" />
<Calendar ID="Calendar2" runat="server" UseRowHeadersAsSelectors="False" UseColumnHeadersAsSelectors="False" EnableWeekends="True"></Calendar>
<DateInput ID="DateInput2" runat="server" DisplayDateFormat="MM-dd-yyyy HH:mm tt" DateFormat="MM-dd-yyyy HH:mm tt" LabelWidth="40%" DisplayText="Select Request Date" EmptyMessage="Select Request Date">
<EmptyMessageStyle Resize="None" />
<ReadOnlyStyle Resize="None" />
<FocusedStyle Resize="None" />
<DisabledStyle Resize="None" />
<InvalidStyle Resize="None" />
<HoveredStyle Resize="None" />
<EnabledStyle Resize="None" />
</DateInput>
<DatePopupButton CssClass="rcCalPopup rcDisabled" HoverImageUrl="" ImageUrl="" TabIndex="30" />
</telerik:RadDateTimePicker>

Hi, we're got a RadGrid on a page with a RadAjaxManager and RadAjaxLoadingPanel. On the first operation, using any of the paging, filtering, sorting etc. the grid doesn't appear to be using ajax on postback. Every other operation after that is fine and works as expected. There are no errors on the client or server side. It's a pretty simple page using version 2018.1.117.40. Thanks!
