Customize grid column on the server

[Sharon Eden]

Hi,

I have a RadGrid that is programmatically bonded to a dataset from data access layer. I’m trying to change the width and header text of a column in the code behind and whatever I try, the columns collection is always empty. I’ve tried using the DataBound and the PreRender events and the collection is still empty. I also tried the ColumnCreated event, but the column in the event arguments has no header text.

How can I customize the column on run time?

I’m using 2010 Q2 controls.

Thanks,

Sharon.

Hi Sharon,

RadGrid.Columns contains the non-autogenerated columns, of which you have none.

Either use the RadGrid.MasterTableView.RenderColumns collection, or the ColumnCreated event to customize columns at runtime.

(see section "Customizing columns programmatically")

I recommend you to use ColumnCreated. The UniqueName of autogenerated columns is the same as their corresponding datafield.

The HeaderText property of a column can be empty if the column is not a GridBoundColumn, so you could check this first, before running other logic in the ColumCreated handler.

Best wishes,
