Can I modify the properties of a content page control from an event fired from the master page?create a delegate and event on master page wire up the master page in the content page create the event handler (function) on the content page modify for example:
contents of the Text property of a textbox render a control visible (or hidden) etc...
I have a very simple user control in my web site project which has public property declarations as following

This is the line where Error shows when i run the project uctTest.StartDate = DateTime.Now;

Using VS 2010 RC, VB, I have a label on a masterpage that is hidden. I want to make it visible from a content page when needed, and have the text change on the label as well from the master page.
I am using the following to access the label, but the text and other properties don't change for some reason.
Dim lblErrorMessage As Label lblErrorMessage = CType(Master.FindControl("lblErrorMessage1"), Label)
lblErrorMessage.Style.Add("display", "inline")
lblErrorMessage.Text = "LoginID ALREADY EXISTS!!! Please choose a different ID"

<form runat="server">

I know I'm probably doing this wrong, but is this possible? I want to change a parameter of that control. It says 'inaccessible due to protection level'.
On my master page , I have "Search textbox" and "Search Button".
On My content page , I have a "User Control" which has a "GridView".It shows some data about Vendors.
Also, on this User Control's Page Load, i have code written to display all vendors in GridView.
Now, when user enters Vendor Number in "Search textbox" , and hits "Search Button" , i want to handle this event inside my User Control.
How to do this ?
I need to access a control inside a repeater and change its properties. To enable it or not. I got an erorr message Object reference not set to an instance of an object. Here is my code inside a method. protected void
rptCAP_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
LinkButton lnDel = (LinkButton)rptCap.FindControl("lnkDelete");
lnkDel.Enabled = false; //<<<<< this is where the error occur
}
The name of the repeater control is id="rptCAP"
If the answer to this question exists somewhere, I'm no good at searching for it. This is sort of a simple question, the response being two parts: (1) is it possible? (2) if so, how?
I've created a web user control for my site's footer. In my web.config I have it registered like this:
[Code]....
Then, within the pages on my site, I simply insert it like this:
[Code]....
But obviously, that didn't work. I get this error: The type or namespace name 'FooterControl' could not be found (are you missing a using directive or an assembly reference?)
So I'm really not sure what to do at this point. I can put all of my code in the ASPX file and make my life easier, but I would kind of prefer not to.
Here's the scenario: A class based on System.Web.UI.Page has been created. A number of content pages derive from this class. All of these content pages use the same master page. The content pages define controls which need to access things on the master page (in code-behind). This is fine - no problem. In particular, each content page has its own data grid. The grid on each page has the same name, so that common code can reference it. In fact, some event handling for the grids on each content page is identical, so would like to factor that code to the base class. Interestingly, I can actually define the event handler entirely in the base class, with no stub in the content class at all, because the wire-up of event handlers uses the event-handler name defined in the grid, and that name happens to be found in the inherited base class. All good and dandy... very cool in fact. The problem comes when the code in the base class needs to access any of the common elements from the content page's master. Remember, the master is the same, and I know the type of the master. I would like to do something like this in the base-class code:
((myMasterType)this.Master).PropertyofMaster=xxx;
The problem is, that myMasterType - the type of the master page the content pages are using - is not available at compile time, at least not from a class definition for a base page. I've found articles that claim that the class name of the master is available - and it is, but not from a separate class. I CAN see it and compile with the master's class name from, for example, the code behind of the various content pages. But the actually class simply isn't available, it seems, from a pure class (the base page class). Judging from other times this question has been asked, here are common misunderstandings offered as solutions: 1. Use a page directive to declare the master type. This is not even vaguely a part of the problem, as the issue is not code in the content page, but in a separate base class which content pages inherit from. That base class is a pure class -- no .ASPX file at all. 2. Pass a reference to the master object from the content page to the base class. This can be done, but is pointless, because I can already get it, using "this.Master" from the base class! But because the type of the master is not available at compile time from the base class, it can't be passed from the content page either - unless it is passed with type MasterPage, thus losing all the properties/methods publically defined in the specific master page class. 3. Move the base page class out of the App_Code folder because the app_code folder is compiled before the other classes, and thus before the master page class. Doesn't work -- put the master page class file right in the same folder with these content pages and their master page, and the master page class is still not available at compile time from within the class. Re-summarized: Base page inherited by content pages. Content pages all use a common master page. Want to access the public properties of that master page from the base page, at runtime. Barrier is that I can find no way from within the base class to cast the master page object to the actual master page subclass being used.
I have a web page (Orders.aspx) that gets some orders and show them in a Gridview .The orders list I get from DB is depend on a field named Status. The page has a master page that contains a Tab user control. The user control has several tabs and every tab has a different Status. Therefor, when the user clicks on every tab, I want to pass a value as status to my content page (Orders.aspx) and then select the orders from DB based on status.
View 1 RepliesI 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?

View 2 RepliesI am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.
