Web Forms :: Updating A Master Page Label Per Page On Site?
Dec 13, 2010
I have a label within my master page that is part of our footer. In the footer, we are wanting to display page specific information. So as you make your way around the site, the footer will contain content about that page along with other data that is universa on the entire site.I had a somewhat similar question some time back that i posted here..
http://forums.asp.net/t/1615850.aspx it was for a shopping cart of sorts..
cartct.Text = ShoppingCart.Instance.Items.Count().ToString() + " Items In Cart";
If Label is in master page, you have to use FindControl to get the Label and udpate its text
((Label)Master.FindControl("cartct")).Text=String.Format("{0} Items In Cart",ShoppingCart.Instance.Items.Count() );
once you select another page, you dont have it anymore,If you want to share data across different pages, consider using Session to save Items count.
The HTML label control is on master page. And I want to access its value on other aspx.cs page. As there are many other control on the master page so i use the recursive function to access the value but NullReferenceException occurs... The code on aspx.cs page is as:
My computer system froze on me, the mouse froze, cntrl-alt-del, did nothing, so I reset it. Did a disk check, and now everything seems fine except for my master Page html code which I was in the middle of editing when it happened. The VB code-behind file is still ok, the designer file still shows ok with all of the controls in it, but I can't get into desgn or source view. It just opens and gives a whole page of hesixecimal code such as as:
i have a usercontrol which fires a mehtod in the masterpage, the method does fire but the placeholder i want to unhide does not until i refresh the page, how can i get around this?
if (this.Page.Master is Whoops) { Whoops barMasterPage = (Whoops)this.Page.Master; barMasterPage.bindBasketSummary(); } public void bindBasketSummary() { plhLoggedIn.Visible = true; }
I have an "Edit" page that uses a FormView bound to an EntityDataSource. The page is called with the ID field of the record to edit in the query string: "EditEmployee.aspx?ID=10". The EDS the FormView is bound to is using: AutoGenerateWhereClause=true and a QueryStringParameter. Below the FormView I have a ListView that contains some child records of the FormView. The ListView is bound to a seperate EDS and also uses the (same) QueryStringParameter.
The problem I am having is when this ListView attempts to Insert or Edt a column I receive an error because I don't have the ID field (EmployeeID) of the parent bound anywhere in the ListView (and obviously, it is setup as a ForeignKey so it fails, like it should). Any advice on the best way to get this ID (EmployeeID) column bound in the ListView? There are many things I can do in code behind, but I would like to solve this in the markup if possible. I can move the ListView so that it is inside of the FormView if necessary.
I have an ASPX page with two columns. The left column has a GridView control that contains a list of article titles as LinkButton controls. When a LinkButton control is clicked, the content of the article is displayed in the right column. Each of the columns is wrapped in an UpdatePanel. So far everything is working .
Each article title has further descriptive text that is defined in the code-behind as labels within a Div object. Each Div is added to a PlaceHolder object on the master page. References to the Div objects are added as attributes to the LinkButton so that JavaScript is executed when the user rolls over the title and the Div object with the descriptive text is displayed.
The rollovers are working fine and displaying the correct text for the first GridView page. However, when I click a button in the GridView's paging row to advance to the next page of the GridView list, the rollovers are not updated. The text is what was defined for the first GridView page of titles. How should I get the PlaceHolder objects to update when the UpdatePanels are updated?
I'm starting with ASP.NET MVC (1.0). I have a problem to resolve. I have developed a web applicaton (an application of articles like e-commerce) with a head (logo and menu). I have defined the head (logo and menu) in the Master page (site.master). Now, I must display the number of articles in the head in a field (like the number of articles in the virtual basket in the e-commerce). I can read the number of articles in the data base (in the controller), but i can't integrate it in the master page.
I run through some code in my debugger that is definitely changing the value of a label on a master page. But it's not changed on the page:
// set the label on the masterpage olbl.Text = Session["TestScriptCount"].ToString() + " Test Scripts"; Label olbl = (Label)Page.Master.FindControl("TestScriptCount"].ToString() + " Test Scripts";
I have a simple SiteMapPath in my master page like below. <asp:SiteMapPath ID="SiteMapPath1" runat="server" SkinID="SiteMap" Visible="true" /><br /> Also I use Web.sitemap and include all static sitemap pages. In my Web.config, I have this: <siteMap enabled="true"/> Currently, many pages uses this static site map for many projects and I'm not supposed to update the master page, but I need to have dynamic site map so that I can add query strings for each navigating pages.
I am allowing my users to upload their own logos. So on the page where they upload their logo I want to replace the existing logo with the newly uploaded logo. I tried the following but none of them worked:
1) Did a Response.Redirect back to the same page and it didn't work.
2) Tried the below code after the image upload is complete and even this didn't work:
I'm creating a web site and I have this question, I installed a label with the name Userlbl in the master page, and the idea that I have, is when somebody opens the website, the label shows the computer's user, in my case Welcome: "Charly_csh"
I tried with this code, that I used before in access and it works, when I load the page on the localhost, but when I load on the server, it shows NETWORK SERVICE
I have master page that has a Telerik radmenu control.
[Code]....
On the content page, I populate this control with menu items.
[Code]....
This part works. The menu items are populated with the correct navigate URLs. The content page allows users to change parameters that are inside an update panel.
[Code]....
After the values are updated, the LoadShareMenu function is called again. I have verified through the debugger that the function is being passed the updated values and that the returned RadMenu is populated with the correct NavigateURLs. However, the RadMenu control on the webpage remains unchanged. The original NavigateURLs remain.What final step do I need to do to cause the RadMenu to update?Here's the code for the FindControlByID function:
I have a VS 2010 and have created some aspx content pages associated with a master page. I want to call a javascript function right when the page loads but am not able to find an onload client side event for these pages which are using asp:content as there only controls. I know that I can put content in them and I have but how do I call the client side onload event from the main content control?
I want to ask can I use the master page to make a full border to the site for example: [URL] and then put the content inside that, or I just only can use master pages to do headers and footers?
In my child page i have an imageButton, which is surrounded by the UpdatePanel. When the user clicks on the image button a record is removed from my database.
In my master page i have literal control which displays the records for the current user (something like Records: 10)
The RecordsCount control is updated on the page Load event of the MasterPage
Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load RecordsCount.Text = GetRecordsCount() End Sub
How can i update the RecordsCount control? I mean i use postbacks for removing records from the database. And currently the RecordsCount control will be updated if the user hits the Refresh button of the Internet browser. How could i apply the Jquery Highlight on the RecordsCount control when the user clicks on the btnRemove button on the child-page?
UPDATE: Well the first question is solved by using javascript
I am using ASP: menu in my site.master page ' but when I clicked on any button or drop down from other page the menu is disappeared. Why my menu is disappearing from the site.master page ?
I have a site with about 4 pages or so. I was asked to implement a very simple security (check if user in database, if not kick out) using active directory and validating against a table of users. I was simply thinking of createing a master page and making all pages inherit that master page. I would then authenticate the users from the master page.
I m facing problem updating a method which shows the count on master page. That method is bind to treeview control.Whenever a data is saved count is incremented to one. but method gets refreshed only when there is a postback. I want it to be updated after every few seconds or whenver there is data saved. there is pretty gud solution with custom ajax that is with json. But that is not possible with exiting solution.i have to redesign the complete treeview structure in html. And with timer control of ajax whole page gets refreshed.
I have a web app that contains 1 master page and a bunch of content pages. One of the content pages is "SysLogin.aspx", which is called from a menu option from the Master Page. When the page is called, the user logs in. However, there is a "Login" button. In the code behind of the Login_Click() event, the the user successfully logs in, they are supposed to be redirected to a "Default.aspx" page and the Main Menu is enabled. Problem is, the app hangs on the redirect statement and it goes to the Catch portion of the Try Catch construct. For some reason, when I examine the exception, it only says "Unable to evaluate expression". Below is my code. My question, other than what I've stated is...should your application be controlled using code in the Master Page or in child pages. My code from the "SysLogin.aspx" is below. It hangs on the highlighted line of code.
Private Sub btnLogin_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnLogin.Click Try If txtLoginID.Text.Length > 0 Then If txtPassword.Text.Length > 0 Then If dbIO.ValidateUser(txtLoginID.Text, txtPassword.Text) Then Session("LoggedIn") = txtLoginID.Text Session("loggedInOk") = "Y" Response.Redirect("~/Admin/Default.aspx") End If End If End If Catch ex As Exception Master.errMsg = dbIO.DisplayError("btnLogin_Click()", "SysLogin", ex.Message) End Try End Sub
I created a Site.Master page for my website. On the site.Master page I created a header that holds a dropdown list of companies. I was hoping that this dropdown list would be available to all pages, however the first page I made was a page with a grid view. I wanted to use the header dropdown list as one of the parameters to fill the gridview. That option does show up. I have all of the control on that actual page available to bind to, but not the Site.Master page.
