I have a drop down list that populates with different actions the user can take with a button they click to perform the action.  My problem is that one of the actions fires a modal popup on the page, but only after the page does a postback because of the button and the drop down list.  I would like for there to be no postback, but only for the action that involves the modal popup.  Can anyone help?

Thanks.

Set the autopostback property of the control to false.

Also, if you want to call a custom function, you can use the control.attributes.add("onchange","return javascript:FunctionNAme();")

make sure you have a return false before the closing braces of the function, to ensure that postback does not happen. This is useful if you want to control the postback.

The autopostback value of my dropdownlist is already false, that is why I have a button the user can click when they are ready to perform the action.  The problem is that the button causes the postback and there is no autopostback property for a button.

 Thanks.

 Hope this helps.

Ok, I understand what it is I am supposed to do.  I'm coding in visual basic.  I created the function and it returns false.  Now for the Button1.Attributes.Add(etc...) statement.  Do I put that in the page_load sub and instead of "javascript: return ButtonClick();", I say "BLOCKED SCRIPT return ButtonClick()" ?  I'm new to this and I'm not sure where to put this statement.  Thanks for your help.

In my previous post where it says BLOCKED SCRIPT, it should say vb-script minus the -.

Yes the attributed.add statement will go in Page_load

When you say coding in visual basic, that I assume is the code behind, i.e. .vb files. If you are ok using javascript for client side, then the code I gave you will work.

For VBScript, if I find something I shall post it.

Hi Kelly,

Can you please explain the solution in detail you found out?

I am having ie 6 and facing a problem where in dropdowns in a page are not visible on popping out the modal popup panel. 

Thanks
