Data Grid View Column Headers

[jasper018]

Hello, I have a data grid view, and what I am trying to do is, grab all the column headers and put them into a combo box or list box. what I have so far is: foreach (DataColumn column in this.dataGridView1.Columns) { this.listBox1.Items.Add(column.ToString()); } I get an error with this, it is: "Unable to cast object of type 'System.Windows.Forms.DataGridViewTextBoxColumn' to type 'System.Data.DataColumn'" Any help would be apreciated. Thanks J

you can try: foreach (DataColumn column in this.dataGridView1.Columns) { this.listBox1.Items.Add(column.HeaderText); }

this.dataGridView1.Columns returns a collection of GridViewColumn, not DataColumn. In this case, the column returned is a specialized version of GridViewColumn which contains a textbox. foreach (GridViewColumn in this.dataGridView1.Columns) { this.listBox1.Items.Add(column.HeaderText); }

Thanks... The end result that I ended up with is: foreach (DataGridViewColumn column in this.dataGridView1.Columns) { this.listBox1.Items.Add(column.HeaderText); }
