How to manipulate DataGrid after binding?

[goodmorningsky]

Hi, all

I bind DataTable to DataGrid from Page_Load event.

 

DataView dvw = ds.Tables[0].DefaultView;

this.dgColorDate.DataSource = dvw;

this.dgColorDate.DataBind();

 

And I want to hide certain column and add some control to cell.

When I try to do it from PreRender event handler.

 

this.dgColorDate.Columns[(int)Lst.MDL_MFG_COLOR_ID].Visible = false;

this.dgColorDate.Columns[(int)Lst.Colors].HeaderText = "Colors";

 

It throws error. When I check it in debug mode, dgColorDate.Column.Count returns 0.

How can I solve this?

You need to do this after your dg is bound.
