Create Sections in Telerik RadGrid.

[Bhanu]

Hi,

We are using Telerik RadGrid version ASP.NET AJAX Q3 2009 SP2 with Visual Studio 2008 and IE 8. I have to display a two-level read-only grid. First level grid will have certain rows and columns. When each row is expanded, the inner / detail level grid should display data in three sections. Please refer to the attached screenshot for reference. All sections / values are read-only. Each section has a different background color and the section name should be displayed in BOLD. Can you explain how to achieve this functionality ?

Your help is very much appreciated.


Thanks
Bhanu.

Hello,

In order to achieve your goal you could use the approach demonstrated in this online demo application. As for the background color you could check this help topic.

Thanks for the response. I used the below link as we are defining the grid programmatically.

As it is noticed that the second level, i.e. the nested level view (for all rows in the grid) is populated while loading the grid itself.
My grid has to retrieve lot of data from the database based on the selected row id. 
Can we make it on demand ?  i.e. the nested level view should be populated only when expand row is clicked.

Thanks

Hello,

I am afraid that there is no built-in way that could be used to achieve your goal. However, depending on the scenario you could cancel the databinding and thus achieve your goal. You could use the ItemCommand event to check whether command is "Expand/Collapse" and then set a global boolean variable which will control the databinding. If the value is false databinding is not processed if it is true you allow the databinding to occur.
