Hello i created a simple RadGrid, see below, with 1 column for each type of column that a RadGrid can hold and i would like to figure out how to simply traverse thru every column and put an arbitrary value in that column or boolean ect. And in particular, i'm trying to figure out how to address the GridTemplateColumns but can't seem to identify or address them at all.
In this link: http://www.telerik.com/help/aspnet/grid/grdcolumntypes.html , the "GridTemplateColumn" example contains a GidTemplateColumn that contains colums for "CustomerID", "CompanyName", "ContactName", "ContactTitle" ect and i'm really trying to duplicate this same example scenario and then traverse thru all columns in this GridTemplateColumn and put an arbitary value in each of these columns, just so i can figure out how address all column types.
And in my example below i would be trying to populate the GridTemplateColumns, TextBox1-4 and put any text value in them.
Thanks for any code examples you may be able to provide!

To access controls in the ItemTemplate of a GridTemplateColumn, you need to use the FindControl method as shown below:
c#:
| foreach (GridDataItem item in RadGrid1.Items) |
| { |
| (item.FindControl("Textbox1") as TextBox).Text = "bbbbb"; |
| } |
Hope tis helps...
