Hide a column in details view programatically

[John]

for the example listed here http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/autogeneratedhierarchy/defaultcs.aspx

I want to hide a column in child table from code behind .. for example if I wanted to hide the order_ID in the child view how would I do that from code behind when the grid has been created programtically.

Hello,

protected void RadGrid1_DetailTableDataBind(object sender, GridDetailTableDataBindEventArgs e)
    {

        e.DetailTableView.Columns.FindByUniqueName("YourColumnUniqueName").Visible = false;
    }

Thanks,

I am creating the grid from code behind programatically and when I try to put the code as listed, it gives me a column not found error.  When I check the number of columns using e.DetailTableView.Columns.count then I get a value of 0 and also e.DetailTableView.RenderColumns.Count
has a value of 2 when there are clearly more columns in the details view

Any thoughts on what I might be missing?

Hello John,

Please try the following approach:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    HideColumnRecursive(RadGrid1.MasterTableView);
}
public void HideColumnRecursive(GridTableView tableView)
{
    GridItem[] nestedViewItems = tableView.GetItems(GridItemType.NestedView);
    foreach (GridNestedViewItem nestedViewItem in nestedViewItems)
    {
        foreach (GridTableView nestedView in nestedViewItem.NestedTableViews)
        {
            GridColumn column = nestedView.GetColumnSafe("OrderID") as GridColumn;
            if (column != null)
            {
                column.Visible = false;
            }
            if (nestedView.HasDetailTables)
            {
                HideColumnRecursive(nestedView);
            }
        }
    }
}

I hope this will prove helpful. Please give it a try and let me know about the result.

Hi Eyup,
I tried you approach and i couldnot get any Result as Expected :( . Please give an alternative for the same. Along with that i want to remove the Nested Gridviews's headers also.

Thanks,

Hi Madhav,

I have created a sample RadGrid web site to demonstrate that the suggested approach works as expected. Please check out the attached application and let me know about the result.
