Trigger both 'onClick' and 'onClientClick' event on an ASP button from Javascript

Question

I'm working on an existing code and came across a ASP button which has a onClick and onClientClick event on it.

I'm trying to generate a click event from an external Javascript file so that both the events are triggered.

I'm using the below line to achive it-

document.getElementById("ID_ReleaseUserAuthPending_okBtn").click();

But the OnClientClick event is being triggered as expected, but the onClick event isn't. i.e., The Javascript method is being processed, but the onClick() in the C# codebehind isn't.

Please help me out if there is any way where I can call the onClick event too.

Thanks in advance.

Is there a return false statement in your on client click js function which is stopping further code execution — Amit Kumar Singh, Jul 13 '17 at 10:13

Hi @Amit No there is a 'return true' statement. The process flows when directly clicked, but doesn't when triggered from JS. — theLearner, Jul 13 '17 at 10:15
Hi @BWA thanks for the reply, but I have tried the approach suggested in the link shared. They don't seem to help us in this scenario — theLearner, Jul 13 '17 at 10:17
may be before reaching at the end of js function there may be return false; or somehow the return true statement is not being executed. put an alert just before return true and check if it's being executed. — Abhishek K. Upadhyay, Jul 13 '17 at 10:22
@theLearner maybe something block postback to serverside. Check postback existance and data in postback. — BWA, Jul 13 '17 at 10:34

From the client click function, from js, call __dopostback. That is underscore underscore do post back. You can google it for sample code. https://www.codeproject.com/articles/667531/dopostback-function

At the end of javascript method put

return true;

statement.

It should work.

It is returned as true @abhishek . The code works fine when directly clicked on the button. The issue is faced when triggered from JS – theLearner Jul 13 '17 at 10:19
