Examples
The following example prints the numbers of the clicked row and column by calling the HitTest method from within the MouseDown event of a System.Windows.Forms.DataGrid control. This returns a DataGrid.HitTestInfo object.
private:
void dataGrid1_MouseDown( Object^ /*sender*/,
System::Windows::Forms::MouseEventArgs^ e )
{
String^ newLine = "\n";
Console::WriteLine( newLine );
System::Windows::Forms::DataGrid::HitTestInfo^ myHitTest;
/* Use the DataGrid control's HitTest method with
the x and y properties. */
myHitTest = dataGrid1->HitTest( e->X, e->Y );
Console::WriteLine( "Column {0}", myHitTest->Column );
Console::WriteLine( "Row {0}", myHitTest->Row );
}
private void dataGrid1_MouseDown
(object sender, System.Windows.Forms.MouseEventArgs e)
{
string newLine = "\n";
Console.WriteLine(newLine);
System.Windows.Forms.DataGrid.HitTestInfo myHitTest;
/* Use the DataGrid control's HitTest method with
the x and y properties. */
myHitTest = dataGrid1.HitTest(e.X,e.Y);
Console.WriteLine("Column " + myHitTest.Column);
Console.WriteLine("Row " + myHitTest.Row);
}
Private Sub dataGrid1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)
Dim newLine As String = ControlChars.Cr
Console.WriteLine(newLine)
Dim myHitTest As System.Windows.Forms.DataGrid.HitTestInfo
' Use the DataGrid control's HitTest method with
' the x and y properties.
myHitTest = dataGrid1.HitTest(e.X, e.Y)
Console.WriteLine(("Column " & myHitTest.Column))
Console.WriteLine(("Row " & myHitTest.Row))
End Sub
Remarks
If the coordinate is not a cell, the property returns -1.
