Hello,
I am developing a batch editing grid using the instructions from this link.
http://www.telerik.com/help/aspnet/grid/grdprogrammaticcreation.html
All looks good so far. But I want to make a dropdown column. I put a label at itemtemplate, and a dropdownlist as edititemtemplate.
But I couldn't manage to get the SelectedValue. The namingcontainer GridDataItem object either returns null, or Telerik.Web.UI.GridBatchEditingHelper.PanelNamingContainer object. Which is not recognizable by Asp.Net.
Anyway what I need is a simple small project that binds a dropdowncolumn or a templatecolumn with dropdown, for batch editing. If we are able to use DropdownColumn instead of TemplateColumn would we so great. Thanks in advance.

Hello Hakan,
When creating the grid programmatically and using template columns you should follow the approach demonstrated in this help article. Additionally I have created a sample website which illustrates how you can use a GridDropDownColumn when the grid is created programmatically and the EditMode is set to Batch. You can find the sample in attachments.

Hey Angel,
Sorry if I couldn't underlined the problem: What I have a problem with is the part that I take the selecedvalues.
Anyway, I managed to do it with GridTemplateColumn though.. When I put a RadDropDownList, grid took the value automatically.

Hello Hakan,
I suppose that the selected value from the drop drown was set by using a data-binding expressions(<%#Eval()%>) and this was causing the problem. In the current implementation of the batch edit mode data-binding expression are not allowed in the EditItemTemplate. The mode is designed in such way that it will automatically fill the value in the input element. If however you have more than one control in the template things should be handled manually like explained in this help article.
