public sealed class HitTestInfo

NameDescription
System_CAPS_pubpropertyColumnIndex

Gets the index of the column that contains the coordinates described by the current DataGridView.HitTestInfo.

System_CAPS_pubpropertyColumnX

Gets the x-coordinate of the beginning of the column that contains the coordinates described by the current DataGridView.HitTestInfo.

System_CAPS_pubpropertyRowIndex

Gets the index of the row that contains the coordinates described by the current DataGridView.HitTestInfo.

System_CAPS_pubpropertyRowY

Gets the y-coordinate of the top of the row that contains the coordinates described by the current DataGridView.HitTestInfo.

System_CAPS_pubpropertyType

Gets the DataGridViewHitTestType that indicates which part of the DataGridView the coordinates described by the current DataGridView.HitTestInfo belong to.

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified Object is equal to the current DataGridView.HitTestInfo. (Overrides Object.Equals(Object).)

System_CAPS_pubmethodGetHashCode()

Serves as a hash function for a particular type.(Overrides Object.GetHashCode().)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodToString()

Returns a string that represents a DataGridView.HitTestInfo.(Overrides Object.ToString().)

NameDescription
System_CAPS_pubfieldSystem_CAPS_staticNowhere

Specifies that the point is not on a cell or cell header. This field is read-only.

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];
           }
       }
   }
