radvirualgrid

[atfat]

hi,

i want to use the radvirtualgrid to add a new row/record to a database but instead of using Tab button to switch between column i prefer to use the enter key.

is that possible, if yes can you give me a sample please ?

Thanks in advance

Hello, Atfat,

If I understand you correctly, you want to move the selection to the next cell when pressing the Enter key instead of the Tab key. To achieve this behavior you can handle the PreviewKeyDown event as follows:

this.radVirtualGrid1.PreviewKeyDown += RadVirtualGrid1_PreviewKeyDown;
private void RadVirtualGrid1_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
        this.radVirtualGrid1.VirtualGridElement.MoveCurrentRight(true);
    }
}

I hope this helps. If you have other questions do not hesitate to ask.

Hello, Atfat,

Please refer to the following sample in VB which result is illustrated in the provided gif file:

   Public Sub New()
        InitializeComponent()
        Me.radVirtualGrid1.RowCount = 30
        Me.radVirtualGrid1.ColumnCount = 6
        AddHandler Me.radVirtualGrid1.CellValueNeeded, AddressOf radVirtualGrid1_CellValueNeeded
       AddHandler Me.radVirtualGrid1.PreviewKeyDown, AddressOf RadVirtualGrid1_PreviewKeyDown
    End Sub

    Private Sub RadVirtualGrid1_PreviewKeyDown(ByVal sender As Object, ByVal e As PreviewKeyDownEventArgs)
        If e.KeyCode = Keys.Enter Then
            Me.radVirtualGrid1.VirtualGridElement.MoveCurrentRight(True)
        End If
    End Sub

    Private Sub radVirtualGrid1_CellValueNeeded(ByVal sender As Object, ByVal e As VirtualGridCellValueNeededEventArgs)
        If e.RowIndex = -1 Then
            e.Value = "Col" & e.ColumnIndex
        Else
            e.Value = "Name" & e.RowIndex + e.ColumnIndex
            e.FieldName = "Col" & e.ColumnIndex
        End If
    End Sub

Is this the result that you want to obtain when pressing the Enter key in the virtual grid? If you have more custom requirements, it would be greatly appreciated if you can provide more information about the desired behavior.

I hope this helps. Please let me know if I can assist you further.
