asp button - problem calling server function

[Bill Crawley]

Hi All,

In my asp page I have:

<asp:Button ID="Button1" runat="server" Text="Button"  OnClientClick="checkFileExtension(MainContent_FileUpload1)" OnClick="Button1_Click" />

when I click the button my onClientClick gets called correctly this is a javascript function. My Button1_click event never gets called. on my aspx.cs page it is declared:

public void Button1_Click(object sender, EventArgs e)

I temporarily removed the onCLientClick event to see if that was interfering with this event, but it still never got called.

Make sure that function checkFileExtension is returning true or false depend upon ur validation? also it will be helpful if you can post the html mark up code

I will laugh my ### off if this works.
Go to developer view, drag a button and then double click on it so it automatically creates the event for click.
Then try your code.

hello,

checkFileExtension

as riteshjain1982 check your javascript function, if it return false then your server side event will not be called

[Bill Crawley]

in my Javascript function I already had return true and return false down their respective paths.

I tried Sapator's suggestion and it did indeed cause my server side event to trigger, however, this triggers regardless of the value returned by my clientside function i.e. return true or false serverside still triggers.

Gotta love Microsoft!

when the client function returns false, I do not want the server fuhnction to trigger, but now it does regardless
