How to define an all capital letters mask

[George]

Hi,

I am trying to define a mask for a meskedinput control as all capital and required letters so normally I would be using something like ">LLL" as the mask.

You mention in your documentation that ">" should be escaped in XAML so I have set the mask property as ">LLL" 

<telerik:RadMaskedTextInput Name="rmb_SMS_CODE"
                HorizontalAlignment="Center"
                Margin="0,10,0,20"
                AcceptsReturn="True"
                Mask= "&gt;LLL">
            </telerik:RadMaskedTextInput>

But this does not work, it does not even work if I define the mask in code as this.mymaskcontrol.mask = ">LLL". The control ignores the capitalisation.

Can you please provide me with some assistance on what I am doing wrong?

Thank you,

Hi George,

Thank you for contacting us.

In order to achieve the desired behavior, you can just specify how many symbols to be required. Basically, you have to add a number after the "L" required symbol and set the AllowInvalidValues property to true. Check the code snippet below:

<telerik:RadMaskedTextInput Name="rmb_SMS_CODE"
                HorizontalAlignment="Center"
                Margin="0,10,0,20"
                AcceptsReturn="True"
                Mask= "&gt;L3"
                AllowInvalidValues="True">
            </telerik:RadMaskedTextInput>

Give this approach a try and let us know if you have any additional questions.

Thank you, that worked just fine, I suggest you include these remarks to your online documentation since it is not that clear, the control works differently with the windows forms version for example.

 

Kind Regards,
