Transferring event arguments to JavaScript in ASP.NET C# through OnClientClick

Currently, I have an asp button on my webpage. In the code behind within the Page_Load method, I am assigning some JavaScript calls in the following manner.

btnExample.OnClientClicking = "functionOne(1,2);"+"function2()";

However, I am encountering a problem where I want to pass the EventArgs received by the Page_Load method to function2(). This is because in function2(), I need to call...

eventArgs.set_cancel(true).

If anyone has any suggestions or solutions, I would greatly appreciate the help. Thank you.

Answer №1

To prevent the post back, it is essential to follow Sachin's advice and include a return false statement in your JavaScript function. Remember to not only add return false within the function but also include it when assigning 'OnClientClick'.

Implementation in Code Behind:

btnExample.OnClientClick = "functionOne(1,2); return function2();";

JavaScript Function:

function function2()
{
    //Perform necessary actions
    return false;
}

Answer №2

From my interpretation of your inquiry, it seems that including "return false;" in function2() would be the appropriate solution. This action will prevent the server side click event of btnExample from being triggered.
