I'm trying to get my content page to be able to access an ASP:Literal on a master page.
I have my content page as:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="viewProduct.aspx.cs" Inherits="AlphaPackSite.viewProduct" Title="Hi there!" %>
<%@ MasterType TypeName="Main" %>
Then my master page called Main.master has:
<asp:Literal runat="server" ID="lblBasket" />[code].....
Unable to find control inside the usercontrol in vb.net
code of master page
[Code]....
code of master page 2
[Code]....
In the web user control i have insert some link buttons like home, contact etc...
in the default page i want to change the linkbutton css class inside the user control....
i am always get nothing value....
I have MasterPage.master and 3 page that use this masterpage
1-home.aspx
2-product.aspx
3-information.aspx
in masterpage I defive 3 DIV
<div id="Home" runat="server"></div> <div id="Product" runat="server">
</div> <div id="Information" runat="server"></div>
I want in Home.aspx it change <div id="Home"> Background's image so I wrote below code in home.aspx behind code:
Home.Style["background-image"]=Page.ResolveUrl("~/Images/Extra/H.jpg"); but this error happen: the name Home doesn't exist in the current context
I think it happen because I define div in masterpage not in home.aspx so if I want do it what should I do?
I have hyperlink in page
<asp:HyperLink ID="HyperLink1" runat="server" class="lblMenuMessage" NavigateUrl="~/Admin/صندوق-پیام.aspx">صندوق پیام</asp:HyperLink>
and css
.lblMenuMessage
{
float:right;
text-align:right;
width:150px;
margin:0 12px 0 0;
color:white;
text-decoration:none;
}
and I want change it's color in behind code so I wrote:
(this.Master.FindControl("HyperLink1") as HtmlGenericControl).Style["color"] = "black";
but below error happen:
Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I'm using the following code to iterate through a list of validators on the page. For each validator, I want to set the background color for the control its responsible for validating. The problem I'm having is that FindControl method is always returning null. From searching the web, it appears the problem is that the page has a master page. Whether this is the issue or not, it's obvious that the FindControl method cannot find the ControlToValidate control.
Method used to iterate all validators on a page:
protected void ShowControlsToValidate(Page page)
{
if (page == null)
return;

I have seen numerous posts with this problem, however none of the solutions have worked for me. I am using asp.net 4.0 forms authentication. I have the following set in my config file.
<authentication mode="Forms">
<forms loginUrl="~/Account/Login.aspx" />
</authentication>
<authorization>
<deny users="?"/>
</authorization>
The login.aspx page uses a master page and styles in a stylesheet located in a folder off the root directory called 'Styles'. I have also add the following to my config file.
<location path="~/Styles">
<system.web>
<authorization>
<allow users = "*"/>
</authorization>
</system.web>
</location>
When the page displays, the login page displays with the master page content, however all of the styles are missing. When I embed styles into the master page the styles show properly, so I know the problem is that the styles are not being accessed from the file. how I can authorize access to the stylesheet?
I have a marqueein master page without any updatepanel .Am updating the content of marquee from content page but it does not reflect. e.g:
((HtmlGenericControl)Master.FindControl("maq1")).InnerText =" fdf fgf gf";
I'm looking for a way to dynamically load a master page in order to get a collection of ContentPlaceHolders within. I would prefer not to have to load a page object to assign the master page to before I can access it's controls, but if that's the only way I'll be happy to use it. This is the way I was hoping it would work:
Page page = new Page();
page.MasterPageFile = "~/home.master";
foreach (Control control in page.Master.Controls)
{
if (control.GetType() == typeof(ContentPlaceHolder))
{
// add placeholder id to collection
}
}
But page.Master throws a null reference exception. It only seems to load at some point when an actual page has been created in the page lifecycle. I even thought of dynamically changing the current page's MasterPageFile on Page_Init(), reading all ContentPlaceHolders then assigning the original MasterPageFile back, but that would be horrible!
Is there a way to load a master page into memory independent of an actual page so that I can access properties of it? My final resort will probably involve parsing the master page contents for ContentPlaceHolders instead, which isn't as elegant but might be a bit faster.
I have two web sites, one is a copy of the other.A page that exists in each website references a master page like this:MasterPageFile="~/Dealermaster.Master"This works fine in one site, but not the other. The master page exists in the root dir of both sites. The pages are in a dir called /Pages. If I copy the master page into the /Pages dir and remove the "~/" it works fine. I am debuging both sites in Cassini.

how to find master page div on content page using jqery and how to make display none and block them..
View 9 Repliesi am using master pages. i want to use findcontrol. but i am not getting expected result. my scenario:
Master Page--> ContentPlaceHolder-->Html Table-->Panel-->placeholder--> here i am dynamically generating textbox controls.
i am using following syntax:
TextBox txtAmt = (TextBox)this.Master.FindControl("EmpJobInfo_Content").FindControl("GBTable").FindControl("PanGB").FindControl("PlaceHolder1").FindControl("tbl").FindControl("txtinstallment");
I tried this much:-
protected void Page_PreInit(object sender, EventArgs e)
{
class1 obj = new class1();
DataTable dt = new DataTable();
dt = obj.get_text();
ContentPlaceHolder ContentPlaceHolder1 = ContentPlaceHolder)this.Master.FindControl("ContentPlaceHolder1");
ContentPlaceHolder1. ????
}
So all I want to do is simply find a user control I load based on a drop down selection. I have the user control added but now I'm trying to find the control so I can access a couple properties off of it and I can't find the control for the life of me. I'm actually doing all of this in the master page and there is no code in the default.aspx page itself.
MasterPage.aspx
[Code]....
MasterPage.cs
protected void goToSelectedPage(object sender, System.EventArgs e)
{
temp1 ct = this.Page.Master.LoadControl("temp1.ascx") as temp1;
ct.ID = "TestMe";
this.UpdatePanel1.ContentTemplateContainer.Controls.Add(ct);
}
//This is where I CANNOT SEEM TO FIND THE CONTROL ////////////////////////////////////////
protected void lnkSave_Click(object sender, System.EventArgs e)
{
UpdatePanel teest = this.FindControl("UpdatePanel1") as UpdatePanel;
Control test2 = teest.ContentTemplateContainer.FindControl("ctl09") as Control;
temp1 test3 = test2.FindControl("TestMe") as temp1;
string maybe = test3.Col1TopTitle;
}
Here I don't understand what it's telling me. for "par" I get "ctl09" and I have no idea how I am supposed to find this control. temp1.ascx.cs
protected void Page_Load(object sender, EventArgs e)
{
string ppp = this.ID;
string par = this.Parent.ID;
}

I am using asp.net 3.5 with C# to build web application. I am using master pages. I had a label in masterpage. I want to set some text in that label from content page. I have written following code for that
Label lbl = (Label)Master.FindControl("lblUserName");
lbl.Text = "Guest";

I am a rookie .net programmer and I am facing this problem when designing the master page. I designed the header in paint and when I am placing it under the header div I am not able to see it on the browser page even though it shows the header in the design of the master page.
