public ref class DataGridViewCellEventArgs : EventArgs

NameDescription
System_CAPS_pubmethodDataGridViewCellEventArgs(Int32, Int32)

Initializes a new instance of the DataGridViewCellEventArgs class.

NameDescription
System_CAPS_pubpropertyColumnIndex

Gets a value indicating the column index of the cell that the event occurs for.

System_CAPS_pubpropertyRowIndex

Gets a value indicating the row index of the cell that the event occurs for.

NameDescription
System_CAPS_pubmethodEquals(Object^)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

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

System_CAPS_protmethodMemberwiseClone()

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

The following code example demonstrates using CellMouseEnter and CellMouseLeave event handlers to determine whether a cell can be clicked. The example updates each ToolTipText property value to advertise the current image layout. This code is part of a larger example shown in How to: Work with Image Columns in the Windows Forms DataGridView Control.

void dataGridView1_CellMouseEnter( Object^ sender, DataGridViewCellEventArgs^ e )
{
   Bitmap^ markingUnderMouse = dynamic_cast<Bitmap^>(dataGridView1->Rows[ e->RowIndex ]->Cells[ e->ColumnIndex ]->Value);
   if ( markingUnderMouse == blank )
   {
      dataGridView1->Cursor = Cursors::Default;
   }
   else
   if ( markingUnderMouse == o || markingUnderMouse == x )
   {
      dataGridView1->Cursor = Cursors::No;
      ToolTip(e,true);
   }
}

void ToolTip( DataGridViewCellEventArgs^ e, bool showTip )
{
   DataGridViewImageCell^ cell = dynamic_cast<DataGridViewImageCell^>(dataGridView1->Rows[ e->RowIndex ]->Cells[ e->ColumnIndex ]);
   DataGridViewImageColumn^ imageColumn = dynamic_cast<DataGridViewImageColumn^>(dataGridView1->Columns[ cell->ColumnIndex ]);
   if ( showTip )
         cell->ToolTipText = imageColumn->Description;
   else
   {
      cell->ToolTipText = String::Empty;
   }
}

void dataGridView1_CellMouseLeave( Object^ sender, DataGridViewCellEventArgs^ e )
{
   ToolTip( e, false );
   dataGridView1->Cursor = Cursors::Default;
}
