Web Forms :: Finding A Way To Access To MasterPage Property From User Control?
Feb 2, 2010
I have a Master Page that has several User Controls on it. The MasterPage code behind does some work to calculate a value that needs to be used in all of the UserControls. From the UserControl code behind, how do I access the public property of the MasterPage that I have set?
I'm having trouble to access a Parent's property in User Control. I don't know how to access the parent. The Parent Page's name is Search.aspx. I saw the example below and tried it:
[Code]....
Than I could access the Parent's Property, but when I ran the website I got these errors:
1. The user control is not declared in the parent page 2. The user contol has a circular reference
I have a hidden field on my default.aspx page. Within default.aspx page I have a user control which has a label on it. I need the label to display the value on the hidden field. How can I go about this?
I'm about another 5 hours down the road into trying to use another ASP.NET control that should be amazingly simple yet for whatever reason I can't seem to get to work.
The StaticSelectedStyle property of a Menu control as described here: [URL]
I can't make it work. I've read forum posts that say it won't work unless I bind the menu controls to a sitemap. I've done that and it doesn't work.
I've gone so far as to copy the example code on [URL] and paste it verbatum into a new aspx page in brand new projects in both VS2005 and VS2010 beta and I STILL can't get it to work (after altering the NavigateUrl of one of the menu items to be the page that the code was sitting on...e.g.
[Code]....
If Microsoft's own example code won't even work I'm not sure I'm feeling very hopeful here. It seems entirely stupid to have to go create my own navigation menu when the Menu control does 98% of what I need it to do (except highlight when it's on the selected page).
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?
The website will have public and private (members) access.I'm using VB and MS access database. Registering, login, MasterPage (Master1), default.aspx and users (members.aspx) pages are already set up. What I wanted or what I'm thinking to do is to also base the members.aspx on the MasterPage.
When a user logged in, I wanted to add additional menu (reserved only to members) to the MasterPage and remove/hide unnecessary menu. Here is a scheme of what I want:
MasterPage + default.aspx: (visible to the public) Menu1 Menu11, Menu12, Menu13 Menu2 Menu21, Menu22, Menu23 MasterPage + members.aspx: (When user login) Menu1 Menu11, Menu12, Menu13 Menu3 Menu31, Menu32, Menu33
If the user logout, it will return to MasterPage + default.aspx. Nowing that if the user authentication successful, he will redirected to members.aspx,
1. how can I, when loading members.aspx, manage the MasterPage so that I can show and hide some of its menu? how to use members controls on the MasterPage?
2. in case I'm wrong with what I'm trying to to do, what is your advice?
3. FYI, I'm using VB. Any code in C# will also be OK. I will just have to convert it.
4. I might probably use placeHolder to show and hide these menu in the Page_load event of members.aspx (refer to what I don't want in 3).
i have a masterpage and an default.aspx page that derives from masterpage. On default.apsx, i list products. when i click add basket buton that product is added to shoppingbasket. i do this using jquery.

I am currently working on an application implementing custom localization features. I have created a number of web user controls for different activities on user designed pages. I wish make my webcontrols to check if the page using the control is a simple page or content page of a master page. In case of simple page we need to change page direction from ltl to rtl. In case of content page we need to change direction of master page.
In my application(ASP.NET 3.5) I have a User Control(ascx) that I have on a number of pages. Sometimes I need to reference certain label from the page ascx is on.
I have a little doubt about creating a login control in the master page within a contentplaceholder.
What i want is to create my own login control in the masterpage, using a loginview inside a contentplaceholder. The code is the following:
[Code]....
So far so good, but now i want to create the logic to do the actual login. In a regular aspx page i'll do it in the cmdlogin click event, but as i'm in the masterpage, i'm not sure if i can do that. I actually tried to do it in the code behind of the masterpage, but it didn't work. What can do?? do i ahve to use the asp.net login control?
I'm working on a project that uses a master page. When the page loads I'm calling a class (which I feed and ID into) to get back certain values for a location that the user has selected. Things like town name etc.
On the home page I have a user control which has some statistics for that location too.
Is there a way that I can get the user control to pull values from the class invoked by the Master Page (which has already been fed the ID, hit the db and pulled back the values), rather than creating a new instance of the class within the user control and having to supply the ID and hit the db all over again? This is now I'm calling the class in the masterpage. I have a method "CheckForStoredLocation" that goes off and gets all the data I need.
I have a MasterPage (MasterPage.master) with 2 child MasterPages (specialMaster.master and standardMaster.master). From the MasterPage.master I need to get at some of the controls in one of the children, specialMaster.master, say for example to hide certain content if a session variable is not null.
I want to use a couple of instances of the same control on a page. The user control is intended to display a list of records in a repeater. The aim is that the second control will show a list excluding the IDs in the first control The control has a number of public properties, including IDsInThisList, and IDstoExclude. The query will exclude the IDs in the second property.
What I would like to do is get the record IDs from the first instance of the control (IDsInThisList), and pass them to the second contro as the IDsToExclude.
I have a test page where I am setting the properties of the controls in code. As you might guess, it's not working! The first control displays the top 3 items, as desired, but the second display the records 1-7, rather than records 4-10 because it is not receiving the IDstoExclude from the first control When I response write the IDstoExclude from the first control in my testpage, the string is empty. (if I do it from within the control, it shows the IDs)
How can I get the controls to fire in order and pass values to each other?

I'm constructing a User Control that will have one Property called "ContractIdx". Here's how I've constructed this Property:
public int ContractIdx { get { return Convert.ToInt32(this.Attributes["ContractIdx"]); } set { this.Attributes["ContractIdx"] = value.ToString(); } }
I'm initially loading the User Control by passing a parameter to it and setting ContractIdx accordingly. That all works fine.
Upon Postback though I'm loading the User Control without any parameters and then setting its ID property to what it was before the Postback. My understanding was that if I did this then ViewState would properly restore everything. Yet apparently this is not the case with the "ContractIdx" attribute.
Where am I mistaken in my understanding? How should I change things to get this mechanism to work?
There is one user control say uControl.ascx. This has a public property Message. There are 2 aspx pages Default.aspx and Home.aspx which has the user control uControl.ascx. When a sumit button from Default.aspx is clicked some action takes place and the value for Message is set and then execution is redirected to Home.aspx. In Home.aspx the value for Message is lost.
Is there anyways that the value of Message is retained for both the aspx pages?
