Hyperlink Relative To Current URL Not Path Of User Control?

Aug 25, 2010

I have a page on my site, for purposes of this example lets say [URL]. On Default.aspx I have a user control called MyControl.ascx which lives in /Controls/MyControl.ascx. So the tree looks something like this

[code]...

Whenever I place a HyperLink control on MyControl.ascx and specify a NavigateUrl, this path is relative to the control, not the URL of the page. So for instance if in NavigateUrl I specified "AboutMe.aspx", the URL would be rendered as [URL] instead of [URL]. Is there any way I can make this relative to the page URL? I've tried the solution here: [URL] but it didn't work for me.

Edit

To clarify, I'd like this to be generic enough so that if I didn't know what the path was the solution would work. So I don't really want to harcode "~/Pages/Default.aspx" in the NavigateUrl

C# - Load User Control Given Its Type?

Mar 5, 2011

Is there a way to instantiate and use a usercontrol (.ascx) if given you have its Type (ie. typeof(MyUserControl))?With regular asp.net controls like a textbox or a dropdownlist you can just make a new instance and add it to a controls collection. This doesnt appear to work for User controls. While you can make a new instance and add it to a collection, and have all of its events fire, it will not actually render to the page. Typically you would call Page.LoadControl() with the path to the .ascxThis presents a problem if all you have is its type. How can you get the path to the .ascx to give to the LoadControl method. Ideally I would also like to not have to have a reference to the Page object

C# -pass A Generic Type With The User Control?

Aug 19, 2010

In Asp.net Web forms why must a user control be partial? I tried to remove the partial keyword and it says: Missing partial modifier on declaration of type 'test'; another partial declaration of this type exists
Where is the other declaration?I am trying to pass a generic type with the user control how can I do that? I can't unless I change the other declaration too. I couldn't find it so I removed the partial keyword.Note:
you do have 3 files if your making WebApplication but if your making website you only get 2 files?
UserControl.ascx
UserControl.ascx.cs
so in website where is the other declaration?the reason i want generic is because im making a Grid User Control so i want to pass the type the datasource is going to have.

Get Code - Behind File To Recognize Type Of A User Control?

Jan 18, 2011

I have a custom control in my mater page that represents a menu, let's call it CustomMenu. The control code files are located in a non special directory. I want to give each page that uses that master page the ability to access the control and, using a public property, tell the control whether or not it should render itself. I have a public property on the control to do that, and I know I can get the control by referencing Page.Master.FindControl('IdOfControlIwant');

The problem I'm having is that I can't seem to get the control Type recognized by the compiler, so when I do find the menu control, I can't actually work with it. The only way I can get the code behind to recognize the type is to register it in the ascx file, and then add at least one control to the page, which is undesirable.

Server Controls In User Control Are Null When User Control Serves As A Base User Control ?

Jun 4, 2010

I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.

If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?

Web Forms :: Put A Breadcrumb On The Site That Allows The User To Walk Back Up The Path They Used To Get Down

May 13, 2010

We have a site that allows a user to drill down through a list. The drill down works by the page calling itself with a different query string. From any level they can choose to go to a different page dealing with the subject matter for that level. All of that works great. However, we would like to put a breadcrumb on the site that allows the user to walk back up the path they used to get down.

Most of the breadcrumbs I have seen do not save the query string. Also, many use some kind of external data provider (database or XML) to build the site map. I am not sure how that would work with the recursive page calls. I don't mind looking at products or coding it myself. I have actualy built something, but it is quirky when people use the browser back button.

Custom Server Controls :: Unable To Use A Web User Control Inside Another Web User Control

Mar 10, 2011

I have a web user control that represents a simple message box. It is used to display simple messages like "Item has been deleted", or "The item was saved successfully".

On the other hand, I have another web user control that represents the item in the form of an editable form (I made this a user control because this is used in two different pages). I want to embed an instance of the message box user control inside the editable form. I am writing this right after the @Control directive:

[Code]....

Instead of using @Register directives, I register the user controls in web.config and so far this has worked just fine.

With the above markup, the project compiles, but whenever I try to navigate to a page that contains this construct, I get an HttpParseException exception. Furthermore, Visual Studio states that the tack w7rc9:MessageBox doesn't represent a known control.

What am I doing wrong?

C# - Web Control Added In .master Control Type Not Found In Child Page?

Jun 7, 2010

I have a Web Site project, and within it I have a user Web Control defined in an ascx file.The control is added to the Site.Master, and it shows up correctly on the page and everything is fine.I need to override some of the control's fields on one of the pages that derive from Site.Master.

// In OnLoad:
MyControlName control = (MyControlName) Page.Master.GetBaseMasterPage().FindControl("controlID"));

The issue is that MyControlName doesn't register as a valid Type on the child page. If I add a second instance of the control to the child page directly, the above works as needed, but if the control isn't placed directly on the page, and instead is only defined in the master page, the type is undefined. The control is not in a namespace, and is defined within the project, so I don't know why it is having such an issue location the appropriate type.If I put a breakpoint in the OnLoad, the type listed for the control is ASP.my_control_name_ascx, but using that does not work either. Why can't the child class reference the correct type? Can I fix this?
