dataGrid[ hti.Row, hti.Column ] = ! (bool) dataGrid[ hti.Row, hti.Column ]

[Jason Huang]

Hi,

In the code:

DataGrid.HitTestInfo hti = dataGrid.HitTest( e.X, e.Y );
dataGrid[ hti.Row, hti.Column ] = ! (bool) dataGrid[ hti.Row, hti.Column ];

Would someone tell me what the line doing:
DataGrid.HitTestInfo hti = dataGrid.HitTest( e.X, e.Y );

Thanks.

Jason

Hello,
This method would be use in a Click Event. It gives information about the
System.Windows.Forms.DataGrid control at a specified point on the screen. e
is the point you have clicked. DataGridHitTest give you the the Clicked
Cell.

Example:

private void dataGrid1_MouseUp(System.Windows.Forms.MouseEventA rgs e)
{
DataGrid.HitTestInfo hti = this.HitTest(new Point(e.X, e.Y));
switch(hti.Type)
{
case DataGrid.HitTestType.RowHeader:
//RowHeader was clicked
break;

case DataGrid.HitTestType.ColumnHeader:
//ColumnHeader was clicked
break;

case DataGrid.HitTestType.Cell:
//a Cell was clicked
break;
}
}
