Filtering Dropdown list in RadGrid

[Meera]

Hi,

I have a RadGrid with three levels. There is one DropDownList in the second level and another one in the third level. The combo in the third level has to be filtered based on the selection in the combo of second level. I tried a few methods but didn't help. I am using SQlDataSource to fill both these combos and having trouble setting the select parameter of the third level combo dynamically

Could you please help?

Thanks
Meera

Hello Meera,

You can attach an event handle to the OnSelecting event of the data source control which the second combo is attached to and there assign the corresponding value to the select parameter.

Hope it helps.

Hi Tsvetoslav,
 
Thanks for reponding

I have two doubts. As per your suggestion I need to pass the corresponding value to the select parameter. My problem is to get this corresponding value which is the selected value of the combo in the first level within the OnSelecting event in the second level. The second doubt is how to trigger the OnSelecting event of the second level combo when the value in the first level combo is changed

Thanks
Meera

Hi Meera,

I had in mind the OnSelecting event of the data-source control - it is triggered automatically when the page is data-binding its controls tree. Anyway, please, open up a formal support ticket and send you files so that we get a better idea of what you are trying to achieve and how exactly you have approached the scenario.
