Progamatically Adding XAML Controls Problem

Posted on 2014-01-29
Last Modified: 2014-02-03
I'm trying to add controls programmatically in my WP8 project but get an error that the StackPanel to which I'm trying to add the controls to is not declared.

Is there some limitation on adding controls in a DataTemplate or is something else going wrong?

   <!--ContentPanel - place additional content here-->
        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <phone:LongListSelector Name="ListItems">
                        <StackPanel Name="DataPanel" Orientation="Horizontal">
                            <CheckBox Name="CheckBoxComplete" IsChecked="{Binding sActive, Mode=TwoWay}" Checked="CheckBoxComplete_Checked" Content="{Binding sStartDate}" Margin="10,5" VerticalAlignment="Center"/>

Open in new window

            Dim newBtn As New System.Windows.Controls.Button
            newBtn.Content = "A New Button"

Open in new window

"DataPanel" is not available directly in your code because it is inside the "ItemTemplate", which means there maybe multiple items that contains "DataPanel".

If you really need access "DataPanel" in your code, you'll have to iterate the items, and use "FindName()" method to find it.

Could I somehow generate the whole datatemplate and add that in code?

I am not sure of that and i would not do that. But i am curious of why you need to "generate the whole datatemplate and add that in code"? What do you really want to achieve? Maybe there is a better solution othan than doing this?

Well It all started with another post..

Original Question

I thought that if I queried the fields of the datasource using reflection, then I could programmatically add the correct type of control to the datatemplate.
