DataGrid::HitTestInfo Class

Contains information about a part of the System.Windows.Forms::DataGrid at a specified coordinate. This class cannot be inherited.


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

public ref class HitTestInfo sealed

The DataGrid::HitTestInfo type exposes the following members.

Public propertyColumnGets the number of the column the user has clicked.
Public propertyRowGets the number of the row the user has clicked.
Public propertyTypeGets the part of the System.Windows.Forms::DataGrid control, other than the row or column, that was clicked.

Public methodEqualsIndicates whether two objects are identical. (Overrides Object::Equals(Object).)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeGets the hash code for the DataGrid::HitTestInfo instance. (Overrides Object::GetHashCode().)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringGets the type, row number, and column number. (Overrides Object::ToString().)

Public fieldStatic memberNowhereIndicates that a coordinate corresponds to part of the System.Windows.Forms::DataGrid control that is not functioning.

The DataGrid::HitTestInfo class, in conjunction with the HitTest method of the DataGrid control, is used to determine which part of a DataGrid control the user has clicked. The DataGrid::HitTestInfo class contains the row, column, and part of the grid that was clicked. See the DataGrid::HitTestType enumeration returned by the Type property for a complete list of grid parts.

To return a DataGrid::HitTestInfo, invoke the HitTest method from the MouseDown event of DataGrid control. Pass the x and y properties of the MouseEventArgs to the HitTest method.

The following example uses the HitTest method in a MouseDown event to return the DataGrid::HitTestInfo object. The row, column, and part of the grid are then printed.

   void dataGrid1_MouseDown( Object^ /*sender*/, System::Windows::Forms::MouseEventArgs^ e )
      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( myHitTest );
      Console::WriteLine( "Column {0}", myHitTest->Column );
      Console::WriteLine( "Row {0}", myHitTest->Row );
      Console::WriteLine( "Type {0}", myHitTest->Type );
      Console::WriteLine( "ToString {0}", myHitTest );
      Console::WriteLine( "Hit {0}", myHitTest->Type );
