Hi
Finally i am able to update my data by typing it by hand. Now i have to insert a dropdown in the Grid. I found advanced custom column in your demo best fits my need. i need a dropdown list pulled from datatable "mytable" and use it for grid. the updated data is same as displayed.
I understand the repeater populates the dropdown
So i tried the code you supplied But it gives me error message
Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Source Error:
If Not Page.IsPostBack Then
Dim MyColumn As EO.Web.CustomColumn = CType(Grid1.Columns(1), EO.Web.CustomColumn)
Dim FloorRepeater As Repeater = CType(MyColumn.EditorInstance.FindControl("mytable"), Repeater)
what is wrong here?
any help would be appreciated

Hi,
It's mostly because you changed the argument for FindControl. FindControl takes the ID of the repeater control. It has nothing to do with your database "mytable". Once you get the repeater control, you can then worry about how to fill it up with data from wherever you database is.
Thanks!
