Hi

I am using telerik radgrid which has GridBoundColumns.

The query that is ran to populate the grid successfully returns the data.

However when the return values from the query is populated in a datatable it is blank and Im not sure why? Using C#

The column on the database is NUMBER datatype.

This is the grid on aspx page.

Any ideas on how to fix this please?

Thanks

Page had an existing working RadGrid control.

Issue started after I dragged a NEW radgrid control onto the page.

Script Error:   

Runtime: Error: 

Script control 'gdtcSharedCalendar' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl

Warning shown in Visual Studio.

c:\tfs\Test\FirmDB\FirmDB.Web\MasterPages\Main.Master: ASP.NET runtime error: Reference assemblies for target .NET Framework version not found; please ensure they are installed, or select a valid target version.

Any suggestions?

Thanks,

Rog

Hi,

 

I am monitoring some document processing on the server with RadProgressArea. How could I hide the progressarea on 100% complete?

 

Thanks, Marc

perhaps just a setting in
response.ContentType = "text/calendar" ?
or is there something that can be done when getting the data?

Dim data As String = Server.HtmlDecode(RadScheduler.ExportToICalendar(LoadContent()))

is there some setting to set to tell it to export the way to make it HTML?

In the CMS I developed, I'm providing administrators with an admin bar in an ASCX file using RadToolBar when viewing content pages. I want to assign icons to RadToolBarButtons and RadToolBarDropDowns, just like the icons on other toolbars in the admin panel, using the icons from the document at https://www.telerik.com/design-system/docs/foundation/iconography/icon-list/. Since other toolbars have text on their buttons, I can simply assign icons using `.rtbText::before`. However, this method doesn't work for the content page toolbar buttons because they don't have text. All the methods I've tried to assign icons to both text-based and textless buttons have led to different problems. The methods in the Telerik documentation are generally written for RadButtons and similar controls. I can find it somewhere

<telerik:RadToolBar ID="RadToolBar1" runat="server">
<Items>
<telerik:RadToolBarButton Text="Settings" SpriteCssClass="fas fa-cog custom-icon" />
</Items>
</telerik:RadToolBar>


CSS:

.RadToolBar .rtbItem .rtbIcon:before {
font-family: 'WebComponentsIcons'; 
font-weight: 900;
}

.custom-icon:before {
content: "\f013"; 
}

This method didn't show any icons either. The classes given within SpriteCssClass are not reflected in the HTML output at all.

The toolbar is already LightWeight.

What's the correct way to do this? The only solution I've found so far that doesn't break anything else is to write the icons directly into the text as Unicode characters, but for system-wide standardization, I would prefer a solution that uses the WebComponentsIcons fonts.

I am trying to obtain an old Telerik release:

RadControls_Q3_2007_SP2

I no longer have an active subscription, but I previously used Telerik products in the past.

Could you please let me know:

  • Is it still possible to access or restore this archived version?

  • If older account or purchase information is available, what would the process be to regain access?

  • What information would be required to verify eligibility?

This request is for maintenance of a legacy application that still depends on this specific version and contains a significant amount of legacy code.

Any guidance would be greatly appreciated.

1. What I have is a Kendo TreeView control similar to the below structure.

-  Parent 1

      - Child 1 of Parent 1

      - Child 2 of Parent 1

- Parent 2

2. What I need is to trigger an event on Double click of any of the items ( items being : Parent 1,Child 1 of Parent 1,Child 2 of Parent 1,Parent 2)

3. There exists an event for single click, that is .Select(). But I don't seem to find one for double click. 

4. Question : Is there any way to trigger a double click event from the control itself, if not, what is the suggested alternate for the same?

Hi,

I have to process the files in the UploadedFiles collection in a certain order (alphabetical). Is that possible from the collection (LINQ?) or should I save the files first to the TargetDirectory and go from there?

This always worked till now:

var chart = $("#ctl00_RecordOverview_rc_heaterpower").getKendoChart();

 

Now we get:

 

service.aspx?id=7&mt=M999&mv=01&ms=00003:217 Uncaught TypeError: $(...).getKendoChart is not a function
    at init (service.aspx?id=7&mt=M999&mv=01&ms=00003:217:83)
    at HTMLDocument.<anonymous> (service.aspx?id=7&mt=M999&mv=01&ms=00003:265:29)
    at i (Telerik.Web.UI.WebResource.axd?

 

Anyone knows what is happening here?

 

Regards,

Marc

With code coming from your demo's I get:

 


Compiler Error Message: BC30517: Overload resolution failed because no 'New' is accessible.

Source Error:

Line 97: 
Line 98:             Dim memStream As New MemoryStream()
Line 99:             Using archive As New ZipArchive(memStream, ZipArchiveMode.Create, True, Nothing)

 

What am I doing wrong?
