Hi everybody
I just have the following problem:
I created a ASP-LinkButton and added a method in the code-behind file for its onclick event. Then I added a break point at the beginning of the method to check if it's called.
Now I added a JS which calls the __doPostback("xxx", ""); exactly like the LinkButton does and everything works fine.
Now I add a Webservice, which validates my input and if everything works fine, its callback should call the click method of the asp-button. Guess what happens: the postback is called, but not the event of the button. If I do this before outside the callback - everything works fine, so I know the code is correct.
I even tried to add a "window.setInterval" timer which always checks a bool and calls the postback as soon as the bool is turned to true ... Then I set the bool after the callback and guess again: The postback is called but not the method ...
I don't have any further ideas for workarounds - anyone got a hint for me?
THANKS!
Hi,
Now I get a general idea of your situation. But your description doesn't give me sufficient information to find the cause.
Accordingly, I made a sample, please try it.
