VS 2010 - Updating Master Page Control From User Control
Aug 19, 2010
I have a label on my master page (called mainMenu) that shows the number of items in a cart. The label wasn't getting updated when the cart was cleared until after an additional postback or redirect so I created a method on the master page called UpdateNumberOfItemsInCart to update the label text.
Using the MasterType directive on the Cart page allowing me to strongly type the master page, I can access the update method from the Cart page. There is a user control also named Cart that actually contains the 'clear cart' button so I setup an event on the user control also called UpdateNumberOfItemsInCart. I wire up the Cart control's event on the Cart page which then makes a call to Master.UpdateNumberOfItemsInCart();
So far so good except when I wrap the Cart control with an update panel the update to the cart count label doesn't happen.

I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page
and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?

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:

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.
<asp:Content ID="Content1" ContentPlaceHolderID="Content" runat="server">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<Triggers><asp:AsyncPostBackTrigger ControlID="btnRemove" /></Triggers>
<ContentTemplate>

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

Basically, I have a user control with a set of input controls such as textboxes and radio buttons. It also has a button along with these controls. What I want is that when the user clicks this particular button, the data entered in the input fields must get updated into a grid in the parent page.

Hosting page:
protected void Page_Load(object sender, EventArgs e)
{
LoadMyControl(Parameters); //Do it every page load to preserve it's state
}
protected void LoadMyControl(string parameters)
{
plchld.Controls.Clear();
Control userControl = LoadControl("TheUserControl.ascx");
userControl.ID = "userControl1";
plchld.Controls.Add(userControl);
}
Now inside this control, when a button is clicked I want to update ,let's say a Label on the hosting page.
What is the best way to do it? Custom event?

I want to share a common page load and page init events sequence between Master page and child page and User Control as described below:
Let us have the following components:-
1. TestMaster.master -> It is the master page
2. TestChild.aspx -> It is the Child page
3. TestUserContrl.ascx -> It is the UserControl present within the TestMaster.master page.

In my user control I got this inline CSS in which I have only css classes... like I am not setting any attribute or whatever on some ID..got only classes like :-
.sp
{
backgrond-image :url(blah blah);
}
and so on..
nothing of the sort
#id1
{
/* set some property here*/
}
Now my question:-
Do I need to worry about system generated IDs if the CSS in my user control got only classes ? like in my page source..the divs ID changes from their original ID to something like ctl00_ContentPlaceHolder2_ctl00_Banner_divBanner after adding usercontrol and master page ...
so changing IDs shouldn't make any difference..right ??

My master page code looks something like this:
namespace Recipes
{
public partial class MasterPage : System.Web.UI.MasterPage
{
...
public void UpdateUserLogin()
{
NicknameLbl.Text = ((Recipes.BasePage)Page).CurrentUser.Nickname;
}
...
}
}
I want to call the UpdateUserLogin() method from a user control, something like this:
((Recipes.MasterPage)this.Page.Master).UpdateUserLogin();
But for some reason the compiler doesn't know Recipes.MasterPage (are you missing an assembly blablabla).
Maybe the problem is that I added the Recipes namespace around MasterPage manually, it wasn't added by VS. By the way I'm using VS Web Developer Express 2008.

I have the following code which at the moment sits in a number of pages:
[Code]....
It sits in the page because I reference the usercontrol type 'emailSignUp' and pass data to an exposed variable 'DisplayType'. The control is located in the pages master page. Ideally what i'd like to do is put this in its own class or something, so I can just call it passing the configuration variable, but I'm unsure how this would work -

I have looked everywhere for how to do this and all I come up with is threads describing how to expose public properties. I have a USER CONTROL in my Master page. It is a search box with a text box and a dropdown for search type (last name, account number, etc) and a search button. When the user clicks the search button, I open a new page that displays the results. How do I pass the values from the USER CONTROL search fields to the new page? I would post code, but I have nothing to post yet since I don't know where to start. I have tried exposing the public property of the user control, but I don't know how to retrieve those values on the results page.

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;
}

We have created a Master page that inherits off the asp.net Master class.We have also got ui controls that inherit off the standard asp.net ui control class.Our Master page has a public member variable. We need to be able to access that member variable from the ui controls that we use.However we can't seem to get at it? Is it our architecture that is wrong? Or the idea itself - user control getting acces to Master page variables?
