See attached image.. this was created in a RadGrid in a GridTemplateColumn.  what I would like to do is make each grid range color different. All values come from a database even the color, Would this be done somehow in itemcreate or itemdatabound.

Thanks

Hi All

Hopefully I'm explaining this clearly ... I'm pretty new to using the rad controls and any help would be appreciated.

I'm trying to find a way of allowing an attachment/file to a new record within a RadGrid that get's uploaded along with the Insert/Update command but I can't seem to figure out a solution. I initially tried using asp:FileUpload but quickly realized that it requires a postback. When I get the FileUpload object (since a postback has not occured) the the control has HasFile returns false even though I "attached" a file.

I also tried using the Rad but keep getting the same results.

Regards

Ralph

Hi,

How can I ​add a value of the PageSize dropdown?  I want to also have the value 5 in the pagesize.  Currently it is 10/20/50 but I need it to be 5/10/20/50.

Another problem, when I have a radgrid with 13 lines and I set the Pagesize to 20 (so greater then the actual size) then the pager disappears and you are not able to set the pagesize back to 10.  How can I avoid the disappearance of the pager?

Kind regards

Suzy

Hi,

I am working on hybrid application. Recently I am having an issue in WIndows 8, when app is starting,  the splash screen shows for a moment, then it hides and a white screen is displayed for a brief moment before the Keno Mobile UI shows. I have added AutoHideSplashScreen in Windows config.xml but it doesn't work in Windows phone. This configuration is working on Android, perfectly OK. I have upgraded Cordova to 3.7.0 version.

Can you give me any suggestions on how to remove white screen flash as the app starts, it looks unprofessional.

Thanks in advance.

Hi guys,

I'm using Telerik Q2 2015 with the release of Export to PDF (multiple pages) using ExportClientManager.

When a user clicked export, the save window popped up asking for open or save the pdf file.

If that user chose save then open the PDF file, everything is good.

But If that user clicked open the PDF then save the file, it showed error code 23 (Please see attachment).

Have anyone been had this issue and is there any solution?

I'm using adobe reader version 11.0.4

 

When adding new ComboBoxItems on the client (JavaScript), and specifically setting the "isSeparator" to true, it does not render correctly and instead still renders as an "rcbItem" in a standard "LI" element and the CssClass "rcbSeparator" is no where to be found (by inspecting the HTML).


Does anyone know how to get Separator items to render correctly when adding them in JavaScript?

I have added a RadDropDownList control on my web page. Along with it I have added a standard Asp.Net button control. When I am clicking on the Asp.Net button the event associated with it is not getting fired. Can anyone tell why is this happening? Is it because of the Rad control? If so then what should I do to make the button click event to work properly?
