Hi Dawid,

After further discussions with the team about this item, we decided that we will not proceed with an implementation as such feature is not directly related to the main functionality of the control and could be easily achieved with an application logic.

I'm attached a sample project that demonstrates 3 different solutions, however the easiest and the recommended one would be to inherent from RadMaskedTextInput and override the InsertCharNoMask method as shown below:

public class CustomTextInput : RadMaskedTextInput
{
    protected override void InsertCharNoMask(char character)
    {
        base.InsertCharNoMask(char.ToUpper(character));
    }
}

Please let me know if you have any questions or concerns.

Hope this will help you.

Hi Dawid,

Thank you for the additional clarification. You are right that without specifying the number of characters, it will not work. Indeed, this will be a good-to-have improvement to our RadMaskedInput control. I can see that you have already voted for this request. In case this request is of interest to more people and gathers enough votes, so its priority gets high enough, then we will consider it and make it part of our future plans. 

I have updated your Telerik Points for bringing this behavior to our attention.

Hi Dawid,

Thank you for the provided solution.

The control provides a way to uppercase '>' or lowercase '<' the entered text. You can use the Mask Modifier Tokens. The Mask property needs to be used in this case. Keep in mind that the '>' and '<' symbols need to be escaped in XAML. Let say for example you have set the 'l' token which means that letters are required and we will need 5. To uppercase, the entered letters check the Mask structure below.

<telerik:RadMaskedTextInput  Mask="&gt;l5" />

I hope this information is helpful.
