I have a gridview that has  drop down defined.  I am having trouble binding a datasource to the dropdown.  

The UI Code and Code Behind code  is attached.  

At the line

drp.DataSource = ds

I am getting an object reference error.  Can someone please help with this.

Thanks.

>drp = DirectCast(RowItem.Cells(0).FindControl("ddlCadence"), DropDownList)

Above line is not working. Its not finding the drop down list.

Should it not be

drp = DirectCast(RowItem.Cells(1).FindControl("ddlCadence"), DropDownList)

Where is your vb code block called?

1: You should do the Dropdown databinding in the GridView RowDataBound

For the error...instead of finding in the cell just find in the rowItem

drp = DirectCast(RowItem.FindControl("ddlCadence"), DropDownList)

Open in new window
