Web Forms :: How To Reference A Master Page Control From A Static Class
Feb 15, 2011my MasterPage I have a label that reflects the name of the module that the user is currently in. I change the label text accordingly using the following ..
private void ChangePageTitle(string PageTitle)
{
Label lblPageTitle = (Label)Master.FindControl("lblPageTitle");
lblPageTitle.Text = PageTitle;
}
Instead of placing this method in the code-behind of every page, I want to put it in a single class and call it accordingly. I thought of using a static class but do not know how to reference the MasterPage.Can I use a static class? or do I place the method in the code-behind of one page and call Object.Method from the other pages?

Web Forms :: Set Body Css Class In Master Page?
Jan 23, 2010I'm trying to write a way of setting the css class on the body tag in a master page from the content form page through a page directive variable. Everything seems like it should work here, however when I use my BodyCssClass variable, the page content isn't generated, just the master page content. Also, if instead of using the page directive variable, I just put <% BodyCssClass = "mybodyclass"; %> in default.aspx, that works.

Page With Base Class With Dynamic Master Page Not Firing Events
May 3, 2010I am feeling that I have terribly wrong somewhere. I was working on a small asp.net app. I have some dynamic themes in the heme folder and have implemented a page base class to load the master page on the fly. The master is having the ContentPlaceHolder like: <asp:ContentPlaceHolder ID="cphBody" runat="server" />
Now I am adding pages that are derived from my base class and added the form elements. I know, Visual Studio has problem showing the page in the design mode. I have a dropdown box and wish to add the event of onselectedindexchange. But it is not working. the page is like this:
<%@ Page Language="C#" AutoEventWireup="true" Inherits="trigon.web.Pages.MIS.JobStatus" Title="Job Status" AspCompat="true" CodeBehind="JobStatus.aspx.cs" %>
<asp:Content ID="Content1" ContentPlaceHolderID="cphBody" runat="Server">
<div id="divError" runat="server" />
<asp:DropDownList runat="server" id="jobType" onselectedindexchange="On_jobTypeSelection_Change"></asp:DropDownList>
</asp:Content>
I have also tried adding the event on the code behind like:
protected void Page_Load(object sender, EventArgs e)
{
jobType.SelectedIndexChanged += new System.EventHandler(this.On_jobTypeSelection_Change);
if (!IsPostBack)
{
JobStatus_DA da = new JobStatus_DA();
jobType.DataSource = da.getJobTypes();
jobType.DataBind();
}
}
protected void On_jobTypeSelection_Change(Object sender, EventArgs e)
{
//do something here
}
C# - Access Master Page / Child Page Controls From Class?
Jul 26, 2010I have a div on my master page and I want to use it for showing page errors. I have an error display class and it works fine. My problem is that in some instances, the error gets displayed even before the tag resulting in (non)-display of the message. This is mostly with code that has response.redirect.
I want to counter this by having the error shown on a div within my master page.
How can I access <div id="errorSegment" runat="server">?

Jun 2, 2010I have a MasterPage project which is a class library project (it includes themes, style sheets, menus etc) and all applications use them.
I am using the BasePage concept for dynamically adding title,meta tags and descriptions. This BasePage Class inherits system.UI.Page and the aspx pages in the project inherits the BasePage class.
Now i need to move this BasePage class from my application to the Master Page Project so that all the projects/applications can reuse the same code.
I tried add the basepage.cs in the App_code folder and tried calling it in the page directive like below
<%@

MasterPageFile="~/Master/Layout/MasterPage.master"
AutoEventWireup="true"

Title="Title"
Meta_Keywords="xxxx,yyyy,zzzz"
Meta_Description="This is a test" %>
But i am getting error
Could not load type '~/Master/App_Code/BasePage<Page>'.
This was working fine till the BasePage class was inside the application. But once i moved it out of the project and added it to the master page project i getting this error.
