[Solved] Check if column exists

[Mattias]

Hi,
I need to check if a column exists or not.
I have a global method that hides the edit/delete buttons on a row but now I have a grid without the edit button.
I tried this but getting error on the if statements: Cannot find a cell bound to column name 'EditCommandColumn'

public static void HideRadGridEditButtonsForReaders(GridItemEventArgs e)
        {
            if (e.Item is GridDataItem)
            {
                GridDataItem item = (GridDataItem)e.Item;
                ImageButton editButton = null;
                ImageButton deleteButton = null;
                if(item["EditCommandColumn"] != null)
                    editButton = (ImageButton)item["EditCommandColumn"].Controls[0];
                if (item["DeleteColumn"] != null)
                    deleteButton = (ImageButton)item["DeleteColumn"].Controls[0];
                if (HttpContext.Current.User.IsInRole(Utilities.RoleTypes.AdministratorReaders.ToString()))
                {
                    if(editButton != null) editButton.Visible = false;
                    if (deleteButton != null) deleteButton.Visible = false;
                }
            }
        }

Hello Mattias,

You can use the GetColumnSafe method to check whether the column exists or not:

if(RadGrid1.MasterTableView.GetColumnSafe("MyColumn") == null)
    //...
