The masked Textbox could do the work, but also blocking other symbols as well.

But the masked textbox not allowing me to change the font size of the text.

Regular Textbox also doesn't provide Font size configuration, right?

[Sugumar_5656]

No, We can change the font size in text box widget.

Hello,

What you can do is create a validator, which fires automatically when the user inputs the text. This validator checks the content for whitespace (it's JavaScript, so consider using regular expressions for that), and if the check fails it can display an error status message and block controls to continue, e.g. "Next" or "OK" button.

The validator will fire once the textbox loses focus, e.g. the user clicks outside or presses ENTER or TAB. If the user selects some other control on the same mashup (e.g. OK button), the text box will lose its focus first, which still gives you the chance to validate his input.

Hello Constantine,

thank you for your work around solution.

but my requirement still differs from this one.

I don't need to trigger the event to execute the validator. the widget itself need to constrain the white space.

Then take a look at "Masked Textbox" widget. In the "Mask" property specify something like "*****", then it will accept 5 alpha-numeric character and no whitespace.
