hi,all

I want to get some cells in DataGirdView by GetChildAtPoint() method.

for example:

private void dataGridView1_DragDrop(object sender, DragEventArgs e)
{

Point point = new Point(e.X, e.Y);
Point pointOfClient = this.dataGridView1.PointToClient(point);

Control control = dataGridView1.GetChildAtPoint(pointOfClient);
string a = ((DataGridTextBox)control).Text;


}

in this method ,I use GetChildAtPoint to get the values of cells,when executed,I found the control is null. I want to know the reason of it .

in addition ,is there another method to help me get the values of current cell when DragDrop.

thanks

Michaelliu

    I think a DataGridView doesn't host any controls except HScrollBar and VScrollBar. You can check it with the following statements:

    For Each c As Control In Me.MyDataGridView.Controls

    Console.WriteLine(c.GetType().ToString())

    Next

    Dim p As Point = MyDataGridView.PointToClient(New Point(e.X, e.Y))

    Dim hti As DataGridView.HitTestInfo = MyDataGridView.HitTest(p.X, p.Y)

    Dim cell As DataGridViewCell = MyDataGridView.Rows(hti.RowIndex).Cells(hti.ColumnIndex)

    Console.WriteLine("Current cell value is: " & cell.Value)
