TextBox in MessageBox

[Gianluc]

Hi, how can I get the text entered in the textbox in a variable of type string in c# ?

<ControlTemplate x:Key="searchTemplate" TargetType="teleSpec:RadMessageBoxControl">
            <Border Padding="12" Background="{StaticResource PhoneChromeBrush}">
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="*"/>
                    </Grid.RowDefinitions>
                    <ContentControl x:Name="PART_Title" HorizontalContentAlignment="Left" FontSize="{StaticResource PhoneFontSizeLarge}" FontFamily="{StaticResource PhoneFontFamilySemiBold}" Margin="{StaticResource PhoneMargin}" />
                    <StackPanel Grid.Row="1" Orientation="Horizontal">
                        <Image Source="SomeImage.png" Margin="12, 12, 0, 24" />
                        <telerikPrimitives:RadTextBox Watermark="Text here"  x:Name="txtSearch" Margin="5,6,0,11" Width="427" />
                        <ContentControl HorizontalContentAlignment="Left" VerticalContentAlignment="Top" x:Name="PART_Message" Margin="12, 12, 12, 24"  />
                    </StackPanel>
                    <CheckBox x:Name="PART_CheckBox" Grid.Row="2" HorizontalAlignment="Left" VerticalAlignment="Bottom" />
                    <ContentControl Grid.Row="3" x:Name="PART_ButtonsContainer" HorizontalContentAlignment="Stretch">
                        <ContentControl.ContentTemplate>
                            <DataTemplate>
                                <StackPanel x:Name="PART_ButtonsPanel" Orientation="Horizontal"></StackPanel>
                            </DataTemplate>
                        </ContentControl.ContentTemplate>
                    </ContentControl>
                </Grid>
            </Border>
        </ControlTemplate>

Hello Gianluc,

Thank you for your question.

You can use our RadInputPrompt control as shown here. When the prompt is closed you will be able to access the text through the returned event arguments.

Let us know if you need further assistance.

I'm trying to reproduce the example on this page http://www.telerik.com/help/windows-phone/radinputprompt-examples.html the section " Creating a control template for RadInputPrompt "

I did everything as explained but the app crashes when I call

     RadInputPrompt.Show ( imageTemplate , " Title", new string [ ] { "yes", "no" });

returning this message when debugging : -

ExceptionObject { MS.Internal.WrappedException : Part name: PART_TextBox1
Part type: Telerik.Windows.Controls.RadTextBox --- > Telerik.Windows.Controls.Exceptions.MissingTemplatePartException : Part name: PART_TextBox1
Part type: Telerik.Windows.Controls.RadTextBox
   at Telerik.Windows.Controls.Primitives.RadControl.GetTemplatePart [T] (String PartName , Boolean ThrowException )

   at Telerik.Windows.Controls.InputPrompt.RadInputPromptControl.OnApplyTemplate ( )
   at System.Windows.FrameworkElement.OnApplyTemplate (IntPtr nativeTarget )
   --- End of inner exception stack trace --- } System.Exception { } MS.Internal.WrappedException

Hello Gianluc,

Indeed, there is an issue with the provided example and we will change it with the next upload of the documentation.

What needs to be changed is the name of the RadTextBox and RadPasswordBox inside the template. According to the example they are named PART_TextBox and PART_PasswordBox, but you need to change them to PART_TextBox1 and PART_PasswordBox1.

Thank you for your report.
