Question

I need to flush my datagrid everytime when a treeviewitem is clicked. My code is given below.

private void treeView1_SelectedItemCh         


        

Answer 1

I have tried several approaches and this was by far the best and most reliable one:

dataGrid.Columns.Clear();
dataGrid.Items.Clear();
dataGrid.Items.Refresh();
