Access DetailTable Columns

[Jack]

I am using Rad Controls 2008 Q3 with Visual Studio 2008, C#, and .netFramework 3.5.

I have two issues:

I have a MasterTableView and two DetailTables.  I need to programmaticially control the display of Edit and Delete columns based on a user's permissions.  For example, I am using Grid.Columns.FindByUniqueName("MasterDelColumn") to locate the Delete column in the MasterTableView.  However, when I try Grid.Columns.FindByUniqueName("DetailDelColumn") to locate the Delete column in the DetailTables, the program displays the following error: Cannot find column with UniqueName 'DetailDelColumn'.  How do I locate the columns in the DetailTables programmatically?

I also need to display/hide the "Expand" icon, also based on a user's permissions.  Is there any way to set the "Expand" icon Visible = false programmatically?


Thank you,
Jack

Hello Jack,

You can access the detail table column using its name property and then hide the column using the above code as shown below:

private void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
       if (e.Item.OwnerTableView.Name == "DetailTableName")
       {
              GridColumn col = e.Item.OwnerTableView.Columns.FindByUniqueName("asd");
       }
}

Also refer to the following link, for more information on how to distinguish between the master and detail tables.

Distinguish grid rows in hierarchy on ItemCreated/ItemDataBound
