Hello,

Thanks for your time and effort. In my sample the code  Click="Button1_Click" and  Click="HyperlinkButton1_Click" has not been generated in the Xaml but in xaml.vb. Now its working fine after I write 'Click' event in Xaml.

Hi,

In another project I am facing a problem while adding a dynamic control to the XamOutlookBar. For example I am adding a XamTreeItem to a XamTree placed inside the XamOutlookBar by clicking a HyperlinkButton which is also inside the XamOutlookBar. While adding the control I get the same error "Object reference not set to an instance of an object."

Please let me know how to solve this.

Thanks,

Irfan

Xaml:

<ig:XamOutlookBar HorizontalAlignment="Left" Height="400" Margin="10,10,0,0" Name="XamOutlookBar1"  VerticalAlignment="Top" Width="200">
            <ig:OutlookBarGroup Header="Sales" HorizontalAlignment="Stretch" Margin="0" Name="OutlookBarGroup1" VerticalAlignment="Stretch" >
                <ContentControl>
                        <StackPanel>
                            <Button Content="Button" Height="23" Name="Button2" Width="75" Click="Button2_Click" />
                            <ig:XamTree Height="100" Name="XamTree1" Width="200" >
                               
                            </ig:XamTree>
                            <StackPanel Height="100" Name="StackPanel1" Width="200" />
                        </StackPanel>
                </ContentControl>
            </ig:OutlookBarGroup>
        </ig:XamOutlookBar>

Xaml.vb

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs)

        Dim tvItem As XamTreeItem = New XamTreeItem
        tvItem.Name = "itm1"
        tvItem.Header = "Item1"
        XamTree1.Items.Add(tvItem)

    End Sub

Hi,

  To fix that you just need to find the instance of the control from it's parent.  Modify your click handler like so:

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs)

        Dim tvItem As XamTreeItem = New XamTreeItem

        'Find the control from inside the parent.
        Dim xamTree1 = XamOutlookBar1.FindName("XamTree1")
        tvItem.Name = "itm1"
        tvItem.Header = "Item1"
        xamTree1.Items.Add(tvItem)

    End Sub

I hope that helps,
Best of luck,

Rich

Hi,

Modifying a little. by replacing the XamTree from OutlookBarGroup1 to OutlookBarGroup2 gives the same error. Can you please let me know how do I get the Instance of the control in this case.

Thank you,

Irfan

Xaml:

<ig:XamOutlookBar HorizontalAlignment="Left" Height="400" Margin="10,10,0,0" Name="XamOutlookBar1"  VerticalAlignment="Top" Width="200">
            <ig:OutlookBarGroup Header="Sales" HorizontalAlignment="Stretch" Margin="0" Name="OutlookBarGroup1" VerticalAlignment="Stretch" >
                <ContentControl>
                        <StackPanel>
                            <Button Content="Button" Height="23" Name="Button2" Width="75" Click="Button2_Click" />
                        </StackPanel>
                </ContentControl>
            </ig:OutlookBarGroup>
            <ig:OutlookBarGroup Header="Stock" HorizontalAlignment="Stretch" Margin="0" Name="OutlookBarGroup2" VerticalAlignment="Stretch" >
                <ContentControl>
                            <ig:XamTree Height="100" Name="XamTree1" Width="200" >
                               
                            </ig:XamTree>
                </ContentControl>
            </ig:OutlookBarGroup>
        </ig:XamOutlookBar>

This is a follow-up to see if you have any questions about capturing a click event.

Thank you,
