Javascript and PostBack on one TextBox

[rockdale]

Hi, All

I have a textbox for user to input SSN, I havea javascript to format
what he input to SSN format, I also have a onChange postback function
to retrieve other info based on the SSN.


<asp:TextBox id="txtSSN" runat="server" AutoPostBack="true"
onKeyDown="javascript:myJavaFunction"></asp:TextBox>

in code behind
protected void SSN_OnTextChanged(object sender, System.EventArgs e)
{
//do database query
}

The OnTextChanged event triggered correct if I do not have the
OnKeyDown Javascript. But if I put the onKeyDown javascript. then the
OnTextChanged event won't get triggered.

Can I put both JavaScript and postback function on one control? If so,
what I did wrong or is there another work around?

Thanks a lot

Try

onKeyDown="return myJavaFunction()"

and make myJavaFunction return true.

I am sorry. In my first post, onKeydown should be onKeyDown="return
myJavaFunction()".

If I remove protected void SSN_OnTextChanged() post back function, My
jjavascript function works fine. but not both.

Again, thanks
