Cascading Dropdowns in Batch EditMode

[Puja]

I have a RadGrid with Batch EditMode wherein I have two RadCombobox 'ProdID' and 'ProdDescription' .

On the click of Add New Button in GridDropDownColumn which is Combobox which populates the first Comobox(ProdID).On the IndexChange of ProdID I need to grab the selected value and query upon database to fetch the values of second RadCombox(Prod Description)

Please tell me how to achieve this with code sample

Hi Puja,

You can find a similar example here: https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/client-side-programming/events/onbatcheditopened.

There are two important bits to note:

• the combo box is generally not supported by the batch editing and if you encounter issues with its functionality, you can try to replace it with a RadDropDownList, or employ the following approach for extracting/populating data in a template: https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/data-editing/edit-mode/batch-editing/working-with-templates.
• you must not make postbacks while using batch editing as this will destroy the current data (see here for more details: https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/data-editing/edit-mode/batch-editing/server-side-api), only callbacks may be used for fetching data.
