How can I trigger a masterpage function from a contentpage in asp.net?

Question

How can I trigger a masterpage function from a contentpage in asp.net?

I am trying to call a function on the masterpage from a content page in the codebehind.

Here is my attempt:

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alert__", string.Format("setStatusBarMessage('{0}',{1});", barMessage, type, ""), true);

The "setStatusBarMessage" function is declared in the masterpage, so this code isn't working.

setStatusBarMessage is a client-side function.

MasterPage:

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Content.master.cs" 

Inherits="F8.CRM.Pages.Content" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

    <title></title>
    <asp:ContentPlaceHolder ID="head" runat="server">
    </asp:ContentPlaceHolder>
</head>
<body>
    <form id="form1" runat="server">
    <asp:ScriptManager runat="server" />
    <div>
        <asp:ContentPlaceHolder ID="MainContent" runat="server">
        </asp:ContentPlaceHolder>
    </div>
    </form>
</body>
</html>
<script type="text/javascript">


    function hello() {
        alert('hi mennan');
    }

</script>

ContentPage :

<%@ Page Title="" Language="C#" MasterPageFile="~/Pages/Content.Master" AutoEventWireup="true"
    CodeBehind="Departman.aspx.cs" Inherits="F8.CRM.Departman" %>

<%@ Register Src="~/Controls/Objects/StudioSideBox/StudioSideBox.ascx" TagName="StudioSideBox"
    TagPrefix="uc1" %>
<%@ Register Src="~/Controls/Objects/Baslik/Baslik.ascx" TagName="Baslik" TagPrefix="uc2" %>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

     my html...

    <script type="text/javascript">

       my script codes...


    </script>

</asp:Content>

This masterpage and content page are contained within an iframe object.

Answer №1

Here is the code snippet you can try:

In the Master Page, I have a function like this:

<script>
    function hello() {
        alert('hi');
    }
</script>

Now, on the content page's page load event:

protected void Page_Load(object sender, EventArgs e)
{
    ScriptManager.RegisterStartupScript(this, this.GetType(), "ntmtch", "hello();", true);
}

It works perfectly fine without adding anything to the content page itself.

Update

Code in the Master page:

<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script>
    function hello() {
        alert('hi');
    }
</script>
<asp:ContentPlaceHolder id="head" runat="server">

</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
    <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">

    </asp:ContentPlaceHolder>
</div>
</form>

First Content Page's code:

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true"
CodeFile="Default.aspx.cs" Inherits="_Default" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
<iframe src="Default2.aspx"></iframe>
</asp:Content>

Code behind of the first Content Page:

 protected void Page_Load(object sender, EventArgs e)
{
    ScriptManager.RegisterStartupScript(this, this.GetType(), "ntmtch", "hello();", true);
}

Here's a suggestion for invoking a server side function from the master page:

    MasterPageName ms = Master as MasterPageName;
    ms.CallFunctionOnMasterPage();

If you need to call a client side function on the master page, you should be able to do so directly since both the master page and content page functions will be rendered on the same HTML page.

To access the functions of a Master Page, we can create an object of the Master Page Class and then call the desired function.

 MasterPageClassName myMasterPage = (MasterPageClassName)Page.Master;

 myMasterPage.Functionname();

This technique can be very useful for achieving specific functionality. Give it a try!

My usual approach is to:

<asp:Literal ID="ScriptLit" runat="server" />

Then in the backend code:

ScriptLit.Text = "<script>executeFunction();</script>"
