DataGridView.HitTestInfo
The following code example illustrates the use of this type. This example is part of a larger example available in the DataGridView.Columns property reference topic.
private DataGridViewCell clickedCell;
private void dataGridView1_MouseDown(object sender, MouseEventArgs e)
{
// If the user right-clicks a cell, store it for use by the shortcut menu.
if (e.Button == MouseButtons.Right)
{
DataGridView.HitTestInfo hit = dataGridView1.HitTest(e.X, e.Y);
if (hit.Type == DataGridViewHitTestType.Cell)
{
clickedCell =
dataGridView1.Rows[hit.RowIndex].Cells[hit.ColumnIndex];
}
}
}
Private clickedCell As DataGridViewCell
Private Sub dataGridView1_MouseDown(ByVal sender As Object, _
ByVal e As MouseEventArgs) Handles dataGridView1.MouseDown
' If the user right-clicks a cell, store it for use by the
' shortcut menu.
If e.Button = MouseButtons.Right Then
Dim hit As DataGridView.HitTestInfo = _
dataGridView1.HitTest(e.X, e.Y)
If hit.Type = DataGridViewHitTestType.Cell Then
clickedCell = _
dataGridView1.Rows(hit.RowIndex).Cells(hit.ColumnIndex)
End If
End If
End Sub
The HitTest method of the DataGridView class returns a DataGridView.HitTestInfo. You can use this method to determine which part of the DataGridView control is located at the specified coordinates. For example, you can call this method specifying the coordinates of a mouse click to determine the row and column indexes of the clicked cell or whether a header cell or scroll bar was clicked.
