Hi,

I am experiencing an exception Sys.ArgumentNullException: value cannot be null: parameter name: panelsCreated[6].

Not sure what is causing it, but I suspect the exception has something to do with RadWindow since it occurs when I open a RadWindow repeatedly.

Thanks in advance.

The markup for the 2 RadWindows are as follows:

The javascript for opening the RadWindows are as follows:

We are using telerik control in our app with windows authentication and upload fails in load balancer with ie11. With Compatibility view it doesn't work either.     

One of the solution that has been posted in the online is to issue a HEAD or a GET request prior to the POST.

How can this be done with the Telerik control?

Thanks!

We have nested Nested tabstrip/multipage(s) and are using RenderSelectedPageOnly="true". It seems that nested tabstrips and the selected child pages are also rendered before the parent tab item is clicked which means for us about 6 pages are rendered as soon as the user hits the home page, incurring not only web but RDBMS traffic.

It seems this example - http://demos.telerik.com/aspnet-ajax/tabstrip/examples/multipage/dynamic-pageview-creation/defaultcs.aspx

still loads the selectedpage="0" before it is clicked (which in our case for instance would be when the parent tabstrip/multipage is loaded.

Is there a way to avoid this behaviour and only load the child selectedpage when the parent tab containing the child tabstrip/multipage is selected?

Hi,

I have two questions.

1. I need to have a client side event handler be called whenever user interacts with any of the RadEditors that exist on the page. What event I need to use?

2. Also, I can't change the markup or the code behind to add this event handler. So, how will I find all RadEditors on the page and attach this event using javascript?

Any help is greatly appreciated.

Thanks,

Ana

Does Grid support export to excel (xlsx) when groupping is enabled?

 Hi,

I am a RadGrid newbie and would appreciate help with a few items.

I am using RadGrid in a SharePoint 2010 visual web-part.  I am also using server side code.

Skin = office2010blue

Here are my questions:

1. How do I declaratively set the font for the rows (not just the header)?

2. How do I specify the columns and their width?

3. How do I at runtime set the background color of individual cells and for entire row?

4. How do I stop inheriting the font color from twitter bootstrap css?

Hi ,
