I have added a radWindow to my page. I want to open it from the code behind, but cannot do it as referenced here:

http://docs.telerik.com/devtools/wpf/controls/radwindow/features/working-with-radwindow#show-the-radwindow

I don't even have the option in intellisense for the .show method.

Any ideas why? I've attached screenshots.

Hello,

I have a databound chart to sqldatasource. In DataBound event on server-side I want to check if the chart has data and if it does not I want to hide it. I've tried this but without any luck (VB.NET):

 Protected Sub RadHtmlChart1_DataBound(sender As Object, e As EventArgs) Handles RadHtmlChart1.DataBound
        If RadHtmlChart1.PlotArea.Series(0).Items.Count = 0 Then
            RadHtmlChart1.Visible = False
        Else
            RadHtmlChart1.Visible = True
        End If
End Sub

Hi Telerik team,

When we enable Skin CDN server, the editor throws "Cross-Origin Request Blocked" error in "Insert external video" popup windows. We have added settings in the web.config on our production server and CDN server. Is there anything we missing?

 <httpProtocol>
          <customHeaders>
                    <add name="X-Powered-By-Server" value="150" />
                    <add name="Access-Control-Allow-Origin" value="*" />
                    <add name="access-control-allow-headers" value="*" />
          </customHeaders>
</httpProtocol>

Please check the attachment for more detail.

Thanks in advance,

Hi,

        I have created a skin named whiteblue based on the metro touch base skin. following the instructions given in http://www.telerik.com/support/code-library/including-custom-stylesheets-as-webresources-to-radstylesheetmanager and http://docs.telerik.com/devtools/aspnet-ajax/controls/stylesheetmanager/overview i have placed a button in the sample webpage and configured enableembeddedskins=false and set skin="whiteblue". 

but the custom skin is not working. Please guide me in this regard where i did mistake. When am running webpage it is not showing any error and simply showing radbutton without any css applied.

Hello,

We are doing feasibility study of using spreadsheet control in our next project. 

We are facing some challenges on UI as mentioned in attached image.

Issue related to indentation of rows and cell selection is only happening when  we are using kendo UI with MVC either by helper method or jquery.

Additional behavior or indent or ctrl+z is very weird.

Please look into these issues and suggest us some work around.

Thanks,

Puneet Jain

Hello,

We are exploring using ASP.NET MVC spreadsheet control for our next project and i need to implement following:

#1 Saving complete JSON is an option but for say like 300 x 300 cells with each cell having some formatting, JSON is becoming huge and browser window become unresponsive. Please suggest any strategy to optimize it further.

#2 Insert column acts in a weird way if all columns have data, then on adding a column, data in last column is lost. Our requirement is such that number of columns should actually increase. Let say, we have 10 columns in spreadsheet, then we click a button titled "Add Column" then number of columns in spread sheet should become 11.

If this is not possible by insert column method, please suggest is it possible on client side to reinitialize spread sheet with updated number of columns and rows.

#3 How to disable row and column headers along with formula section ?

#4, do you have any roadmap and tentative date for implementation of this feature ? Demos on your site are updated with 2016 Q1 release beta, when can we expect be able to download the same ? Do you have a list of expected features in that release ? 

Thanks,
Puneet

I replaced the old Telerik DLL with the latest and now enter becomes double spaced.    Why is it being wrapped in <p> now?

http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

I can duplicate it with Chrome and IE11.
