[RESOLVED] Datagridview and ContextMenuStrip

[lkallas]

Hi!

On my Form there is a DataGridView that has a ContextMenuStrip bound to.
ContextMenuStrip has one button "Delete".

When I Right click on DataGridView then it displays the ContextMenuStrip, highlights entire row BUT the little arrow on the rowheader doesn't come along. That means if I click "Delete" button it will delete the row where this arrow is positioned.

Is there a way to get around this problem?

Here is my code for deleting:

Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click

        Try
            If Not DataGridView.CurrentRow.IsNewRow Then
                DataGridView.Rows.Remove(DataGridView.CurrentRow)
                Me.Validate()
                Me.BindingSource.EndEdit()
                Me.TableAdapterManager.UpdateAll(Me.DataSet)
                MsgBox("Row deleted successfully!", MsgBoxStyle.Information, "Database")
            End If
        Catch ex As Exception
            MsgBox("Row was not deleted (row not selected)", MsgBoxStyle.Information, "Database")
        End Try
    End Sub

And here is my DataGridView right click code:

Private Sub DataGridView_CellMouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView.CellMouseDown


        If e.Button = Windows.Forms.MouseButtons.Right AndAlso e.RowIndex >= 0 AndAlso e.ColumnIndex >= 0 Then
            DataGridView.ClearSelection()
            DataGridView.Rows.Item(e.RowIndex).Selected = True
        End If

    End Sub

P.S!
Have tried with event cellmouseclick too...doesn't work.

DataGridView1.SelectionMode = DataGridViewSelectionMode.CellSelect

[lkallas]

DataGridView1.SelectionMode = DataGridViewSelectionMode.CellSelect

I have tried with different selection modes. They select the row but the arrow on the rowheader remains its position(when I use right click).
With left click the arrow on row header comes along.

It does? Not on my system it doesn't! Screenshots?

I have removed the content of this post because the member posting never responded to my suggestion which is inconsiderate.

This is when the cell is leftclicked(notice that the little arrow is on the same line as the highlighted row).



Now the right click. As you see the cell that I clicked highlights the row, but the little arrow doesn't come along. Which means that if I click delete or any other button that gets the selected row index it will apply to the row where the arrow is, not the higlighted one.





My current datagridview allows to add new lines and edit lines...

A selected row doesn't have to be the current row. Your right click sets the row to selected, but this doesn't automatically makes it the current row. Your delete code trying to delete the current row which may or may not be the selected row...

Hi again!

Did some rethinking and came up with this solution:

Private Sub RihmatabelDataGridView_CellMouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles RihmatabelDataGridView.CellMouseDown

        
        If e.ColumnIndex >= 0 And e.RowIndex >= 0 And e.Button = Windows.Forms.MouseButtons.Right Then
            If RihmatabelDataGridView.Rows(e.RowIndex).Cells(e.ColumnIndex).Selected = False Then
                RihmatabelDataGridView.ClearSelection()
                RihmatabelDataGridView.CurrentCell = RihmatabelDataGridView.Rows(e.RowIndex).Cells(e.ColumnIndex)
                RihmatabelDataGridView.Rows(e.RowIndex).Cells(e.ColumnIndex).Selected = True
            End If
        End If


    End Sub

It works if users are and aren't allowed to edit or add rows to datagridview.

Thank you for thinking along, appreciate it!
