Question

So I have a gridview in a windows form application and when I click my button the gridview is populated, the title column/row reads Tag (because I set it that way(below code)) but what if I wanted the Tag title to be replaced with what ever is typed in a textbox, how would I change the below code?

Tag = n.Element("GroupName").Value

Full code:

        XDocument xDoc = XDocument.Load(tagUri);
        var Tag = xDoc.Descendants("Group")
            .Select(n => new
            {

                Tag = n.Element("GroupName").Value, // Tag in this line represents the column name, I would like this changed to be a textbox input. 
            })
            .ToList();

        dataGridView4.DataSource = Tag;

You can set the column’s header afterwards:

datagridView4.Columns[0].HeaderText = textbox1.Text;
