Can't get GetTemplateChild() to work in RC0

09-26-2008 2:14 PM |

Hi,

I have a generic.xaml file looking like this:

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:c="clr-namespace:RgControl">

    <Style TargetType="c:MyControl">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="c:MyControl">
                    <Grid>
                        <ItemsControl x:Name="myItemsControl">
                            <ItemsControl.ItemTemplate>
                                <DataTemplate x:Name="rgDataTemplate">
                                    <StackPanel Orientation="Horizontal">
                                                                   
                                    </StackPanel>
                                </DataTemplate>
                            </ItemsControl.ItemTemplate>
                        </ItemsControl>
                        <Border BorderBrush="LightBlue" BorderThickness="1" CornerRadius="0,0,10,10" VerticalAlignment="Top" HorizontalAlignment="Left">
                            <Grid x:Name="myContentControl"></Grid>
                        </Border>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

</ResourceDictionary>

 In the OnApplyTemplate() method I do like this:

base.OnApplyTemplate();
var myContentCtrl = (Grid)this.GetTemplateChild("myContentControl");

 But the GetTemplateChild() method is returning null. This worked in beta 2, but I can't get it to work in rc0.

 Can anybody help?

 Did you move the generic.xaml to the "themes" folder? That's a breaking change in RC0.

Could you give me please a detailed explanation? I have no generic.xaml in my Solution Explorer. There was workarround in Beta2 for the TabItem bug (TextBox on TabItem focus) with that code:

public partial class myTabItem : TabItem
    {
        public ContentControl ElementHeader;
        public override void OnApplyTemplate()
        {
            base.OnApplyTemplate();
            this.ElementHeader = (ContentControl)this.GetTemplateChild("Header");
            if (this.ElementHeader != null)
            {
                ElementHeader.IsTabStop = true;
            }
            this.ElementHeader.MouseLeftButtonDown += new MouseButtonEventHandler(ElementHeader_MouseLeftButtonDown);
        }
        void ElementHeader_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            try { this.ElementHeader.Focus(); }
            catch (Exception ex) { }
        }
    } 

The bug on TabItem still exists, but above code doesn't work. The line:

this.ElementHeader = (ContentControl)this.GetTemplateChild("Header");
gives a null value and the line:
this.ElementHeader.MouseLeftButtonDown += new MouseButtonEventHandler(ElementHeader_MouseLeftButtonDown);

gives an error: "Object reference not set to an instance of an object".
B.

Do you have your own template defined for the MyTabItem? Or you just used the default TabItem template that come with the Silverlight? If this is the case,  then it's not the issue of the location of the generic.xaml. It might be the default Template for TebItem changed. You have to take a look at the RC0 default template for TabItem.

I did not find an element named "Header" in this template:

<!--TabItem-->

        <Setter Property="IsTabStop" Value="False"/>
        <Setter Property="Background" Value="#FF1F3B53"/>

        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="Padding" Value="6,2,6,2"/>
        <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
        <Setter Property="VerticalContentAlignment" Value="Stretch"/>
        <Setter Property="MinWidth" Value="5"/>
        <Setter Property="MinHeight" Value="5"/>
