Everything thing related to the RADGrid is working fine, but RADTabStrip is not working as expected, when I select "Contact Information" which is 2nd tab page inside the RADTabStrip it is not actually selecting it and so the content of the 2nd Page "PageView 2" is also not showing.

what i am missing here? do i have to configure something in the update panel for RadTabStrip?

kindly write the code as i am new to Rad World.

Pie Chart Labels clipped

Hello,

I'm using the Pie Chart but instead of showing the absolute values in the label, i wanted to show the series name in the label to not need a legend and keep my interface clean. This I could do easily by setting the clienttemplate of the labels. However, after rendering the labels are not displayed proper. They are clipped (see attachments).
It seems that the width of the svg element is actually larger then the width of the containing div that is generated despite them both being the width I set for the control (300px).

Is there anyway to make these labels fit in the container so they are not clipped?
I have limited width on my page because I show more pie charts in a row.

Thanks

[Solved] RadMenu and styling

Hi there.
I am almost this close to buying the RadControls ASP.NET Ajax. I do however need to see if this will work.
Can someone kindly tell me how to style the menu items from:

http://demos.telerik.com/aspnet-ajax/menu/examples/appearance/imageonly/defaultcs.aspx?#qsf-demo-source

similar to the following:

http://www.stunicholls.com/menu/pro_dropdown_2.html

I am not sure how the styling works and how to make it look very similar/close to that as possible. I would really appreciate any samples/advice on this.

Even the sample shown on the telerik demo page link above would be great, showing me all the styling colors, fonts, background etc... etc... but not using images (unless to make it a standing out/3D effect but have the menu name as text only)

Thanks again

Changing sort on already sorted column causes different column to be sorted

I have a radGrid in a user control which is loaded dynamically into my page via code. I am able to sort any of the sortable columns in ascending order by clicking the column header. when I attempt to change the sort to descending by clicking a second time on an already sorted column, the sortable column immediately preceding the column I clicked on gets sorted in ascending order. This does not happen when this same user control is referenced directly in the page (not loaded dynamically). Vewstate is enabled.

This is just really odd behaviour which has me stumped. i thought it might be that the sorting was attempting to use a column index for sorting, and was somehow using the wrong index. I added a breakpoint to the grid's SortCommand event handler and the information in the GridSortCommandEventArgs (e) says that the sort expression that will be applied on the second click is from the preceding column, not the column I clicked. I am not hiding or showing columns and the column that is ultimately sorted is not necessarily the column immediately preceding the column I clicked...it is the preceding column that is sortable.

I have attached screen shots of my grid after the first sort and second sort on the same Status column. In these screen shots, the Recipients column is not sortable.

Thanks for the help!
