DataGridView.HitTestInfo Class
Contains information, such as the row and column indexes, about a specific coordinate pair in the DataGridView control. This class cannot be inherited.
Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The DataGridView.HitTestInfo type exposes the following members.
| Name | Description | |
|---|---|---|
 | ColumnIndex | Gets the index of the column that contains the coordinates described by the current DataGridView.HitTestInfo. |
| ColumnX | Gets the x-coordinate of the beginning of the column that contains the coordinates described by the current DataGridView.HitTestInfo. |
| RowIndex | Gets the index of the row that contains the coordinates described by the current DataGridView.HitTestInfo. |
| RowY | Gets the y-coordinate of the top of the row that contains the coordinates described by the current DataGridView.HitTestInfo. |
| Type | Gets the DataGridViewHitTestType that indicates which part of the DataGridView the coordinates described by the current DataGridView.HitTestInfo belong to. |
| Name | Description | |
|---|---|---|
| Equals | Determines whether the specified Object is equal to the current DataGridView.HitTestInfo. (Overrides Object.Equals(Object).) |
| GetHashCode | Serves as a hash function for a particular type. (Overrides Object.GetHashCode().) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| ToString | Returns a string that represents a DataGridView.HitTestInfo. (Overrides Object.ToString().) |
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.
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];
}
}
}
