setting column width on render

[Aaron]

I am dynamically creating a datatable and a radgrid with autogenerated columns to display report information .
Some of the column headers are fairly long so I would like to increase the columns widths, I'm just not sure when the columns are generated. I tried changing them on ItemDataBound, it doesn't seem to recognize them.

           RadGrid gv = new RadGrid();
            gv.ID = "tmpGrid";
            gv.MasterTableView.HeaderStyle.VerticalAlign = VerticalAlign.Top;
            gv.MasterTableView.HeaderStyle.Width = Unit.Pixel(200);
            gv.ItemDataBound += new GridItemEventHandler(gv_ItemDataBound);
            gv.AutoGenerateColumns = true;
            gv.DataSource = master;
            PlaceHolder1.Controls.Add(gv);
            gv.DataBind();

       void gv_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridDataItem)
            {
                foreach (GridColumn gc in e.Item.OwnerTableView.RenderColumns)
                {
                    gc.HeaderStyle.Width = Unit.Pixel(200);
                }
            }
        }

Please help.

Hi Aaron,

Try setting the width of the autoGeneratedColumns in the ColumnCreated event of the Grid.

CS:

 protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)
    {
        if (e.Column.ColumnType == "GridBoundColumn")
        {
            e.Column.HeaderStyle.Width = Unit.Pixel(100);
        }
    }

Thanks
Shinu

Thanks Shinu,
I tried your solution and as I debug it hits that method when I add the grid to a placeholder on the page, but I still don't see a change.
Do you think it may be because I have a large number of columns in the grid?

Hello Aaron,

Try setting the TableLayOut property for the MasterTable to true as shown below and see if it helps:
aspx:

<telerik:RadGrid ID="RadGrid1" AutoGenerateColumns="true" runat="server" OnColumnCreated="RadGrid1_ColumnCreated" >
        <MasterTableView TableLayout="Fixed" >
          ....

Thanks
Princy.
