I have a RadPanelBar inside of a RadAjaxPanel. When an item is clicked on the RadPanelBar, I dynamically load a user control that uses a ModalPopupExtender. After a button is clicked on the user control and it causes a postback, everything works as intended and I can click another item on the RadPanelBar and everything works. When the user control is closed by the CancelControlID property of the ModalPopupExtender however, it doesn't cause a postback and the next time I click an item on the RadPanelBar, the RadAjaxLoadingPanel persists.

What the page looks like on load before any clicks: http://i.imgur.com/drnCcNO.png

What the rad panel bar looks after click on an item: http://i.imgur.com/czikveQ.png

Modal Control is loaded: http://i.imgur.com/rDT07Yw.png

After Modal control is closed without causing a postback, when clicking on an item in RadPanelBar again, it seems to be even more dim: http://imgur.com/YZNmRpM

 Now when user control is loaded again, the loading panel persists: http://i.imgur.com/TAXnRH4.png

I am just getting started with learning the Telerik products and I see there is info on Radgrid for ASP.net AJAX which indicates it is the newest version.  How can I tell which version I am using so I don't waist my time reading documentation on the wrong product.

Thanks

How do I control a RadButton's visibility state from the codebehind?

For example, if a user is not yet logged-in, then I want to hide the logout button.

Hi - I've been searching for a way to do this but haven't found the "correct" way.

I have a RadGrid - on it are multiple RadNumericTextBox columns - one of those columns is txtQTY.

 In the save form logic I need to get the value of that column from each of the records in the rad grid to build a table of values to pass to the database.  All that worked fine back in VS 2003.  I did the following back then:

 double X

x = ((RadNumericTextBox)(this.raddgActivityGroup.Items[i]).FindControl("txtQTY")).Value;

 But in this version VS 2013 and newest telerik AJAX controls - I get the following problem:

Error 271 Cannot implicitly convert type 'double?' to 'double'. An explicit conversion exists (are you missing a cast?) 

I can get rid of the problem by changing the line to read:

 x = ((RadNumericTextBox)(this.raddgActivityGroup.Items[i]).FindControl("txtQTY")).Value.Value;

but I have no idea why that works and am very concerned that I might be breaking something.

HELP!?!?

Thanks

I'm following the tutorial here to do some conditional styling on a radGrid.

http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/appearance-and-styling/conditional-formatting

But I am not able to use this:

 The visual studio message is "Unknown entity 'color'

and the display error message is:

"Compiler Error Message: CS0103: The name 'Color' does not exist in the current context"

What am I missing? Thanks!

Hi I have an issue with 'Paste from Word' option of telerik Editor. When i copy some text from MSWord and paste it in the editor using 'Paste from Word'  option, the indentation of  some lines changes. I also tried this on Telerik's demo site:
http://demos.telerik.com/aspnet-ajax/editor/examples/cleaningwordformatting/defaultcs.aspx

and the issue is present there as well. I have attached  original document and the screenshot of the changed indentation after using 'Paste from Word'.

I have tried this on IE and Chrome as well and the issue occurs on both.

Please look  into it as this changes the text to an unacceptable format.

Thanks
