Validatetextbox: A self-validating TextBox control (with C # source code)

Control

Because many servers do not support validation controls on settings

So the page with the validation control will have problems with the client button not being submitted

Every time you write JS code to verify the data is too troublesome,

Then there is the problem of the textbox itself, when the TextMode property is set to Multiline, the maxlength fails

For the above question, I wrote this inherited from the textbox using JS in the client data validation of the custom control,

It is almost the same as a textbox, except that a set of validation-related attributes are available on the property panel, and the appropriate configuration can achieve the validation you want.
