How to make RadMaskedTextInput behave like normal textbox

[Henri]

Hi,

I'm trying to make the RadMaskedTextInput behave like the plain textboxes, but taking advantage of built in clear button.
I can not make it behave like a normal text box, especially related to tab order, caret position etc.
(using. v2013.2.729.1050, with theme Expression_Dark)

Here is my code:

<Grid x:Name="LayoutRoot">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="120"/>
            <ColumnDefinition Width="20"/>
            <ColumnDefinition Width="120"/>
        </Grid.ColumnDefinitions>

        <telerik:RadMaskedTextInput Grid.Row="0" Grid.Column="0"
                                    HorizontalAlignment="Stretch"
                                    Mask="" InputBehavior="Insert" SelectionOnFocus="CaretToEnd" TextMode="PlainText"
                                    SectionsNavigationMode="None"  />
        <telerik:RadMaskedTextInput Grid.Row="0" Grid.Column="2"
                                    HorizontalAlignment="Stretch"
                                    Mask="" InputBehavior="Insert" SelectionOnFocus="CaretToEnd" TextMode="PlainText"
                                    SectionsNavigationMode="None" />

        <TextBox Grid.Row="1" Grid.Column="0"></TextBox>
        <TextBox Grid.Row="1" Grid.Column="2"></TextBox>
    </Grid>

Thank you for your assistance.

Hello Henri,

We designed the RadMaskedTextInput control to behave like the native TextBox when the Mask property is set to "" (empty string). Can you please elaborate more on your scenario so we can decide if there is an easy approach to achieve all of your requirements.

It will be great if you can send us your current implementation and specify the behavior that you need to be changed to match the native control.

Thank you for your kind cooperation.

Hi Pavel,
If you try the snippet in my post, you can see clearly the difference in behavior between the two textboxes and the two radmaskedtextinputs. Just look at how the caret is positioned, what is selected, how the next control gets the focus.
Best regards,
Henri

Hi Henri,

 Let me try to suggest some possible ways to solve these issues:
1) Position of the caret. In normal textbox the caret goes to the end of the text when the focus is received by tabbing with keyboard. In Q2 2013 SP we created an attached property to solve this in MaskedTextInput:

<telerik:RadMaskedTextInput Grid.Row="0" Grid.Column="2" maskedInput:MaskedInputExtensions.CaretToEndOfTextOnFocus="True"

where:

xmlns:maskedInput="clr-namespace:Telerik.Windows.Controls.MaskedInput;assembly=Telerik.Windows.Controls.Input"

2) Focusing. We have this issue in our PITS and we will do our best to have it fixed for Q3. As a temporary workaround you can use the GotFocus event handler like so:

private void RadMaskedTextInput_GotFocus(object sender, RoutedEventArgs e)
       {
           var tBox = (sender as RadMaskedTextInput).ChildrenOfType<TextBox>().FirstOrDefault();
           if (tBox != null)
           {
               tBox.Focus();
           }
       }

3) Could you please elaborate more on the selection issues you have experienced?
4) Currently there are also issues with misplaced symbols when user types quickly. Again, we will try to resolve them for Q3 next month. Regards,

Hi Petar,

Thank you for the attached sample, it improves a little but there are still problems.
 
Unfortunately, when the second RadMaskedTextInput field has the focus,
it is impossible to tab back (shift+tab) into the first RadMaskedTextInput.
This in contrast to the two textboxes on second row.

Also, when you freshly load the page , directly  click in the second RadMaskedTextInput, the browser is frozen.

Best regards,
Henri

I want to let you know that in hotfix 2013.2.0923 the issue is not resolved.
Clicking on the X (clear) in the radmaskedtextinput gives an error:
