Datagridview CellDoubleClick event not getting fires with Datagridview drag drop functionality in VB.NET Window form

Differentiate between DataGridView Mousedown and CellDoubleclick events OR Datagridview CellDoubleClick event not getting fires with Datagridview drag drop functionality in VB.NET Window form Problem In VB.NET with Visual Studio 2005 I face a problem with working Datagridview drag and drop functionality. When I write a code to implement drag and drop functionality in Datagridview MouseDown event Ex: DataGridView1.DoDragDrop(Index, DragDropEffects.Move) And trying to fire CellDoubleClick event for same datagrid then this event is not getting fire, problem is when you do double click then first MouseDown event will fire then CelldoubleClick, but if control goes to MouseDown event then this line of code "DataGridView1.DoDragDrop(Index, DragDropEffects.Move)" canel CellDoubleClick event and CellDoubleClick event not getting fire. Solution To work with Both events togather we have to differenciate this by "Clicks" property in MouseDown event Ex: Private Sub DataGridView1_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseDown ' 'Clicks' property can be used to solve this issue If e.Clicks = 1 Then ' Write Code for Single Click Else 'Write code for Double Click End If End Sub Source code So finally cell double and drag drop code should be like below Private Sub DataGridView1_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseDown 'Get the Index of Row which is being Dragged 'We would use this Index on Drop to identify which Row was dragged and get the values from that row Dim Index As Integer If e.Button = Windows.Forms.MouseButtons.Left Then Index = DataGridView1.HitTest(e.X, e.Y).RowIndex If e.Clicks = 1 Then ' For Single Click If Index > -1 Then 'Pass the Index as "Data" argument of the DoDragDrop 'Function, 'Instead of Index as "Data" we can pass some data like 'array, object or images, 'That can be collected DataGridView2_DragOve event like 'e.Data.GetData(GetType(System.String)) DataGridView1.DoDragDrop(Index, DragDropEffects.Move) End If End If End If End Sub Private Sub DataGridView1_CellDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellDoubleClick MessageBox.Show("DGV1_CellDoubleClick") End Sub Private Sub DataGridView2_DragOver(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles DataGridView2.DragOver e.Effect = DragDropEffects.Move End Sub Private Sub DataGridView2_DragDrop(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles DataGridView2.DragDrop 'Write your code do operation in DataGridView2 End Sub
