DataGridView.HitTest Method

Returns location information, such as row and column indices, given x- and y-coordinates.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public DataGridView.HitTestInfo HitTest(
	int x,
	int y
)

Parameters

x
Type: System.Int32

The x-coordinate.

y
Type: System.Int32

The y-coordinate.

Return Value

Type: System.Windows.Forms.DataGridView.HitTestInfo
A DataGridView.HitTestInfo that contains the location information.

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.

The following code example illustrates the use of this method. This example is part of a larger example available in the 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];
            }
        }
    }
