Question

So I want a Button1 to be clicked when the submit button has been clicked.

Here is the relevant code:

<input id="Submit1" type="submit" value="Search" onclick="javascript:check_user()" /> 
<script type="text/javascript">
            function check_user() {
                document.getElementById('<%=Button1.ClientID%>').click();
            }  
</script>
<asp:Button id="Button1" runat="server" Visible="false" OnClick="Button1_Click"/>

And here is the error I get:

Microsoft JScript runtime error: Unable to get value of the property ‘click’: object is null or undefined

Does anyone have any ideas as to what the problem might be? I’ve been tearing my hair out trying to work it out.

Answer 1

Can’t you just do it with a single button?

<asp:Button id="Button1" runat="server" Text="Search" OnClick="Button1_Click"/>

Server-side code:

protected void Button1_Click(object sender, EventArgs e) {
    // processing code here
}
