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.

Regards,

Irfan

Hello Irfan,

You should use the FindName method to find the button first ant after taht you could get it's properties. Inside you button event handler you could use the following code :

Dim

tb As String

"Button2")

tb = Button2.Content.ToString

which will help you. If you are having any question please feel free to ask!

Regards, Nikola.

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>

Hi,

Sorry for the delayed response. It did work perfectly as expected.

Thank you very much,

Irfan

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

Thank you,

Hi,

  Basically you have a collection of Groups in the Outlookbar.  You need to give each Group a key so then you can later find that group.  Once you've found the group, you can grab the control you looking for.

1.)  You need to extend you Xaml to include Keys for each group:

        <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" Key="ouGroup1" 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" Key="ouGroup2" VerticalAlignment="Stretch" >
                <ContentControl>
                    <ig:XamTree Height="100" Name="XamTree1" Width="200" >

                    </ig:XamTree>
                </ContentControl>
            </ig:OutlookBarGroup>
        </ig:XamOutlookBar>

2.)  Then in the code behind, grab the proper group, and then look for your Tree:

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

        Dim tvItem As XamTreeItem = New XamTreeItem

        'We can use the key from the Xaml to get our group
        Dim ouBar2 = XamOutlookBar1.Groups("ouGroup2")

        If (ouBar2 Is Nothing) Then
            Return
        End If

        'Now we can check that instance of the group to find our control
        Dim xamTree1 = ouBar2.FindName("XamTree1")

        If (xamTree1 Is Nothing) Then
            Return
        End If

        tvItem.Name = "itm1"
        tvItem.Header = "Item1"
        xamTree1.Items.Add(tvItem)

    End Sub

Hope that helps,
Thanks,
Rich
