Hello everybody,

I have 3 textboxs (asp.net control) in my aspx page.

I want to check data enter these 3 textbox, but only compel enter 1 of 3 textboxs. i.e when second textbox entered data then first and third textbox can entered or do not entered.

How do I do that by using Validator control?

Thank so much,

Check in Javascript,if three textbox values are null,ask the user to enter value in any one of the textboxes. No Need for Validator control.

You can use a custom validator to validate the situation
