GridDropDownColumn fixed size?

I've added a GridDropDownColumn within a RadGrid and set DropDownControlType="RadComboBox".
The binding and updating works fine.
It's just that the size of the drop down box is much bigger than the three or four items that are in the DropDown.

I tried converting it to a GridTemplateColumn and using a normal RadComboBox and this worked with the size of
the dropdown matching the number of items in the dropdown.

An example can be found at http://demos.telerik.com/aspnet/prometheus/Controls/Examples/Integration/GridEditors/DefaultCS.aspx?product=grid and clicking on the Title dropdown.

Thanks in advance.

Retrieve Values During Insert Command

I have a RadGrid on a page that the auto-insert, update and delete just is not going to work for me based on multiple tables that need to be touched as a result of a single event against the LinqDataSource.

I have been trying for the better part of the afternoon to handle this programatically.

The handler has been created and I can get into it, but in exploring the object, I cannot seem to retrieve the values that I am inserting when clicking on it.

protected void rgLocations_InsertCommand(object source, GridCommandEventArgs e)

{

GridEditableItem item = (GridEditableItem)e.Item;

}

I am trying to retrieve a string from the textbox on the auto-generated insert form and cannot seem to find the value anywhere.

How can I get the values from these forms?

radcombobox to filter a column?

I made a custom column so I could filter with a MS DropDownList but the problem is when the viewstate is false the it doesnt fire an event when you select the first item in the list. So I tried replacing with a RadComboBox and got what I expected until I clicked on an other button in the grid. But It appears the RadComboBox always fires the SelectedIndexChanged even if I clicked on a different button on the grid. Since this in turn fires a command event on the grid the end result is that nothing works anymore.

Is there a solution to this?

Thank you.

GridView with Group By and Client Select

Hi,

I need to construct grid view that allows the user to setup multiple grouping by columns but also displays a check box next to each node. The issue is that a check box needs to be displayed on the parent row of each one of the groups and allow the user to select all the child rows inside.

Any ideas on how to accomplish this if at all possible?

Thanks
