Mouse Right Click

[Javier Gonzalez de Aragon]

Is it possible to select an item in a ListView using the mouse right button?

Thanks,

Hello Javier,

Thank you for your question.

Currently, RadListView does not provide such a built-in option, but you can achieve this behavior by handling the MouseUp event of your RadListView. The following code snippet demonstrates this:

void radListView1_MouseUp(object sender, MouseEventArgs e)
{
    if (e.Button == System.Windows.Forms.MouseButtons.Right)
    {
        BaseListViewVisualItem item = this.radListView1.ElementTree.GetElementAtPoint(e.Location) as BaseListViewVisualItem;
        if (item != null)
        {
            this.radListView1.SelectedItem = item.Data;
        }
    }
}

I hope you find this useful. In case you have any additional questions, do not hesitate to ask.

Thanks for the reply. I'm using Visual Basic and used the following code:

If (e.Button = System.Windows.Forms.MouseButtons.Right) Then
    Dim item As BaseListViewVisualItem = TryCast(lvMovimientos.ElementTree.GetElementAtPoint(e.Location), BaseListViewVisualItem)
    If (item IsNot Nothing) Then
        lvMovimientos.SelectedItem = item.Data
    End If
End If

but nothing happens.

Any ideas?

Thanks,

Hello Javier,

I have tested the code you have posted in VB and it works correctly. Please make sure that your event handler is properly fired. Here is the full code of the handler in VB:

Private Sub RadListView1_MouseUp(sender As System.Object, e As System.Windows.Forms.MouseEventArgs) Handles RadListView1.MouseUp
    If (e.Button = System.Windows.Forms.MouseButtons.Right) Then
        Dim item As BaseListViewVisualItem = TryCast(RadListView1.ElementTree.GetElementAtPoint(e.Location), BaseListViewVisualItem)
        If (item IsNot Nothing) Then
            RadListView1.SelectedItem = item.Data
        End If
    End If
End Sub

Please let me know if you are still experiencing difficulties.

If I remove the TryCast, I get the following exception:

System.InvalidCastException was unhandled
  Message=Unable to cast object of type 'Telerik.WinControls.UI.DetailListViewDataCellElement' to type 'Telerik.WinControls.UI.BaseListViewVisualItem'.


Any ideas?

Regards,

Javier

Hello Javier,

The code I have previously posted is valid for RadListView in ListView or IconView mode. When your RadListView is in DetailView mode, it has some more complex structure of rows, columns and cells. Here is how you can achieve the desired behavior when RadListView is in DetailView mode:

Private Sub RadListView1_MouseUp(sender As System.Object, e As System.Windows.Forms.MouseEventArgs) Handles RadListView1.MouseUp
    If e.Button = Windows.Forms.MouseButtons.Right Then
        Dim clickedCell = TryCast(Me.RadListView1.ElementTree.GetElementAtPoint(e.Location), DetailListViewDataCellElement)

        If clickedCell IsNot Nothing Then
            Me.RadListView1.SelectedItem = clickedCell.Row
            Me.RadListView1.CurrentColumn = clickedCell.Data
        End If
    End If
End Sub

I hope this helps. Do not hesitate to ask if you have any further questions.

Always Null?

Missing property?

  if (e.Button == System.Windows.Forms.MouseButtons.Right)
      {
        BaseListViewVisualItem item = this.lvwDetalle.ElementTree.GetElementAtPoint(e.Location) as BaseListViewVisualItem;
        if (item != null)
        {
          //this.radListView1.SelectedItem = item.Data;
        }

Hello Minkook,

Thank you for writing.

The provided solution by IvanT Todorov from 06-Jun-2012 demonstrates a similar approach for accessing the right clicked DetailListViewDataCellElement. However, it directly uses the RadListView control, but you use the sender which is similar. If you have any additional questions, please let me know.
