Custom Server Control Does Not Cause Validation

[KarlCharlotteNc]

I have a custom server control that renders a Submit button.

The button renders just fine at design and run time.
The button click event is being trapped normally.

My problem : If I add a textbox and a required field validator, my button does not cause either the normal client or server side validation to occur.

Is there a method I must call or an interface I must implement to get my custom control wired up on the Page like a normal Button control. A normal button gets the OnClick Javascript added automatically when rendered if a validation control is no the page. In addition a normal Button control causes the Page.Validate method to run.

Thank you so much for your help,

Karl

Re: Custom Server Control Does Not Cause Validation

In your rendered HTML for the button, create an onclick attribute with the
text from the Page.GetPostBac kEventReference . The only concern is that this
method may need to be called during the OnPreRender phase. Its probably too
late to call it in Render. If you are using Render to create the button's
HTML, call GetPostBackEven tReference in OnPreRender and save the string in a
field until Render.

Re: Custom Server Control Does Not Cause Validation

because you are rendering the html, you have to add the javascript call
yourself.
