Question

net/C# application, I have a user control containing a button.

I am loading the control in a PlaceHolder on the main page at runtime.

<asp:PlaceHolder ID="PlaceHolder1" runat="server">

</asp:PlaceHolder>

Code Behind:

MyControl CC = (MyControl)LoadControl("Controls/MyControl.ascx");
PlaceHolder1.Controls.Add(CC);

on the main page I have a text box and a link button. I want to do the following:

When the user clicks on the button in the user control, the textbox value is set to ‘5’ and the link button click event is fired using javascript.

I tried the following but it did not work:

IN THE MAIN PAGE:

<asp:TextBox ID="PageBox" runat="server"></asp:TextBox>
<asp:LinkButton ID="LinkButtonPage" runat="server" onclick="LinkButtonPage_Click" Text="Submit"></asp:LinkButton>

IN THE USER CONTROL:

<script type="text/javascript">
    function SetPage(a) {
        var txtFld = document.getElementById("PageBox");
        txtFld.value = a;
        document.getElementById('LinkButtonPage').click();
        return false;
    }
</script>

<input type="button" id="Button1" onclick="SetPage('5');" value="Submit"/>

But when i click on the button nothig happens.

Thank you for any help

Answer 1

I fixed the problem by adding the function directly in the onclick event of the button

<input type="button" id="Button1" onclick="document.getElementById('PageBox').value='5';document.getElementById('LinkButtonPage').click();return false;" value="Submit"/>
