Hi there...

I'm a noob at silverlight. I'm trying to change the style of a watermarked textbox, but i'm getting the error: "{StaticResource wtbtmplate} is out of range". What's  the problem? What i'm doing wrong?

Page.xaml:

<WatermarkedTextBox Template="{StaticResource wtbTemplate}" Height="96" Width="19" FontFamily="Verdana" FontSize="36" />
 

App.xaml:

Here i have the default style and template for the watermarkedTextBox control (Present in silverlight documentation - March 2008):

<Style TargetType="WatermarkedTextBox" x:Key="wtbTemplate">

            <Setter Property="BorderBrush" Value="#FF000000"/>
            <Setter Property="BorderThickness" Value="1"/>
            <Setter Property="FontSize" Value="11"/>
            <Setter Property="FontFamily" Value="Trebuchet MS"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="WatermarkedTextBox">
                        <Grid x:Name="RootElement" >

...

</Style>

Hope you can help, and sorry if this a stupid question...

Thanks

Looks like the WatermarkedTextBox class is not mapped to the default xmlns name space. As shown in this MSDN example, you may to do this:

xmlns:local="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Extended"

<Style TargetType="local:WatermarkedTextBox" x:Key="wtbTemplate">

            <Setter Property="BorderBrush" Value="#FF000000"/>
            <Setter Property="BorderThickness" Value="1"/>
            <Setter Property="FontSize" Value="11"/>
            <Setter Property="FontFamily" Value="Trebuchet MS"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="local:WatermarkedTextBox">
                        <Grid x:Name="RootElement" >

Hi Jim... Thanks for the reply

I had try that... Now I have: 

app.xaml

<Style TargetType="local:WatermarkedTextBox" x:Key="wtbTemplate"
                    xmlns:local="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Extended"
                    xmlns:controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls">

     <Setter Property="BorderBrush" Value="#FF000000"/>
                <Setter Property="BorderThickness" Value="1"/>
                <Setter Property="FontSize" Value="11"/>
                <Setter Property="FontFamily" Value="Trebuchet MS"/>
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="local:WatermarkedTextBox">

...

</Style>

page.xaml

<WatermarkedTextBox Template="{StaticResource wtbTemplate}" Height="96" Width="19" FontFamily="Verdana" FontSize="11"/>

Same error: "Attribute {StaticResource wtbTemplate} value is out of range."

Any suggestions?
 

The issue turns out to be something very simple :)

You were accessing a style from the template property. Change Template="{StaticResource wtbTemplate}"  to Style="{StaticResource wtbTemplate}"

 I had change that too and nop, didn't help:

<WatermarkedTextBox Style="{StaticResource wtbTemplate}" Width="96" Height="19" Margin="3"></WatermarkedTextBox>

<Style TargetType="local:WatermarkedTextBox" x:Key="wtbTemplate"
    xmlns:local="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Extended"
    xmlns:controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls">

            <Setter Property="BorderBrush" Value="#FF000000"/>
            <Setter Property="BorderThickness" Value="1"/>
            <Setter Property="FontSize" Value="11"/>
            <Setter Property="FontFamily" Value="Verdana"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="local:WatermarkedTextBox">

...

</Style> 

?  

I realized that myself, and was trying to figure out the problem. So it turns out that for the WatermarkedTextBox you cannot set style as of now, but you can set its template explicitly (see Item # 7 in http://blogs.msdn.com/keithjones/archive/2008/03/05/silverlight-2-beta-1-hints.aspx). So you need to change the code to:

<WatermarkedTextBox Template="{StaticResource wtbTemplate}" Width="96" Height="19" Margin="3"></WatermarkedTextBox>

And in App.Resources (remove the style just put the template there):

<ControlTemplate TargetType="local:WatermarkedTextBox" x:Key="wtbTemplate"
    xmlns:local="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Extended"
    xmlns:controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls">

I have a similar issue and I was trying to follow the steps that you took but obviously I'm missing something. My app.xaml does not compile. Can you show me the code that you have for the watermarkedtextbox in the app.xaml file?

Thanks!
