Change display text of a group

[Dany V]

Hi,

By now I'm grouping by expressions programmatically, what I want to do is to change the text displayed on the group header, I mean, I'm doing this:

Dim expression As GridGroupByExpression = GridGroupByExpression.Parse("PROJECT[Project ID] Group by PROJECT")

so the result in the grid is like this: "Project ID: Project1" (being Project1 the field in the database), but what happen if the field of the database, PROJECT, is empty? the result will be: "Project ID: "; is there a way to write "Empty" instead of " "(blank)???...I don't want to modify the database.

Thanks in advance!

Hello Daniel,

You can try the following code snippet in ItemDataBound event in order to change the GroupHeader text if the field is blank.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridGroupHeaderItem)
    {
        GridGroupHeaderItem headeritem = (GridGroupHeaderItem)e.Item;
        if (headeritem.DataCell.Text =="ProjectID: ")
        {
            headeritem.DataCell.Text = "Empty";
        }
    }
}

Hope this helps,
Shinu.
