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";

i 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'm trying to find a TextBox in the code-behind page, it's inside a nested master page and also then inside another control container (it's inside ctrlCheckoutShippingAddress also) .
I've tried this:
[Code]....
[Code]....
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 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'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 want to include view content page in my master page: My MVC application Left Menu MainPage. The Left Menu and Main page are two contentHolders in the master page. How can I add the Left Menu (View content page) to my Master page?. The Left Menu page is going to be a permanent page. The Content in the main Page is going to change. Left Menu content needs to be the permanent content for all other pages.
I searched in the internet, but I didn't find any solution that solves my problem. Basically I need some permanent menu items in the left page. But, I should not write the code in my master page. I need to add that Menucontent as my contentPage to the master. I have tried that by adding a New content page called "LeftPage.aspx" in View/Home folder.I have referred this page to the master "Left content holder". As the ASP.Net MVC talk to the controller, the left menu is not getting displayed while page loading.If i specify the ControlAction for this left page and specify the URL as //Home/Left ;then the page is getting displayed with only the left page content.
How to access controls in master page using javascript? The master page consists of a search textbox, on key down event of the control I call a javascript function writtern inline of the master page. I get the value of entered in textbox in that javascript function. I have tried giving document.getElementById("<%=txtSearch.ClientID %>").value as well as document.getElementById("txtSearch").value. Both display error. I have to access the textbox control from within the master page itself!
View 1 RepliesI'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'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].....
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.
