Custom Server Controls :: Accessing Properties Of A User Control From The Inherited Code Page?
Mar 8, 2010
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.
I have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.
Is there a way for the user to set that variable in the properties window after they drag the control onto a form.
I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.
Right now, I have to create the control dynamically. I read the query string and then created the object.
I have a public property defined in code behind of a user control. I want to toggle visibility of controls in the markup based on the property's value.
I would like to ask you what is the best practice for developing composite user web control with multiple controls inside from the stand point of dealing with properieties. In my situation I would like to use header menu bar with logos, buttons, java baset visible/hidden menus itc as web control. I was successfull in implementing new control in my project.
But my question goes to issue of properties for ALL OF controls. I know how to hard code all required properties like: text, visible, enable for all controls. It's a lot of work. ( This is the very edge of my asp.net comprehension ) Is there a more elegant way provide an access to controls's properties without hard coding seperatelly?
I have a piece of code that is just HTML. It was previously created as a user control. Within the application i'm working with there are two seperate websites that are interlinked to make one website. There is a documents section where users do not need to login and a data section where users need to login. The design was implemented long before I was hired. My problem is I want to use the code from the documents website with the data website but I can't seem to register the control. I only one this piece of code in one place so when it is updated it doesn't have to be in multiple places. I tried setting "src=http://website/doc/doc.ascx" but this errors out saying
If a composite server control normally encapsulate styling information inside, it is an example of code encapsulation and modularization. However if css properties are included inside the composite control, it is not ideal for code/styling separation and css code re-use principles. Now which consideration should be the main consideration?
I have to use inline code for an aspx page and I need to use a custom server control that is defined in the same aspx page but the control does not get processed as a server control. it gets returned as is as static html tag.
The above code compiles without any error. Also I can drag and drop this control from the Toolbox of my Project on my web form. However I am unable the change the value of my fromLabel control.It allows me to change the value in the properties window.But when I run the form it always shows me its default value which is "From". I want it to be flexible so that any one can change the value in the properties window.
I'm building this small control. It should detect client resolution and set height and width values within two separated HtmlInputHidden controls. But tester property is not getting values froms this control.
[ToolboxData("<{0}:UIControlResolution runat=server></{0}:UIControlResolution>")] public class UIControlResolution : Control { HtmlInputHidden _txtwidth = new HtmlInputHidden(); HtmlInputHidden _txtheight = new HtmlInputHidden();
i have a <div> named 'mydiv' on a web page and have set it's runat property as <server> so it is visible within
my vb.net server side code.
i can see the mydiv within the server side code.
my question:
how do i adjust the height/style of the <div> withion the vb.net code so that whe the page is posted back the new height/style settings apply. how do i get to the style properties server side?
I have a custom server control inheriting from CompositeControl. It consists of two RadioButtonlist controls that are rendered side by side in an html table. The number of ListItems in each RadioButtonList is not known until runtime. Depending on how many items each list contains, the RepeatColumns property of each list is set differently. To do this in the handler for the ItemDataBound event I need to get the count of ListItems in each RadioButtonList. How do I expose the Items.Count property of each internal RadioButtonList as a top-level property? I tried using a getter to return the count but this generates a compile-time error to the effect that the count cannot be assigned to--even though I have not created a setter.
Similarly, in the handler for the Submit event, I need to get the ClientID of each internal RadioButtonList to pass to a method that checks for data changes. How do I expose the ClientID of each component RadioButtonList as a top-level property?
I can of course index the Controls collection of the composite control to access the child control and read its properties--but that defeats the whole point of making a complex, independent custom server control.
I have developed a User Control in inline code model and convert this into dll and try to add it into Visual Studio ToolBox. It shows error "There is no component found in the object.". It is showing actually because i have not added ToolBoxData attribute just before the class declaration, because there is no class declaration in the inline code model. I don't know where i have to add ToolBoxData attribute.
i have a user control page and only have , which i have <div> and a gridview inside <div>how can i add a scroll bar in user control page?the code like below in aspx:<@regrister url="user control page" tagname="xx" tagprefix="aa"><div><aa: id="xx"></div> <--to embed user control page.
I am trying to extend the TreeView and TreeNode class and use it in an .aspx page. My development environment is VS 2005. I put the following code inside of a single .cs file in my App_Code folder:
public class MyTreeview : TreeView { protected override void TreeNode CreateNode() { return new MyTreeNode(); } } public class MyTreeNode: TreeNode { public MyTreeNode():base(){} }
I want to now use my inherited Node and TreeView in my .aspx file. I have the following directive, which is throwing an error -> File is in the special directory App_Code which is not allowed. I tried putting everything into an .ascx file, but I think I am not specifying the class and inheritance directives correctly.
My intention is to give the user a flexible user control on a master page that does the following:
When navigating, a child page will pass the URL (with querystring) and PageTitle to the user control. The user control will take those two parameters and insert them as a "breadcrumb" object at first index of a List<breadcrumb> collection
This part works fine through the use of a Repeater with a LinkButton contained in an ItemTemplate. The user sees each of the pages he has been visiting in descending order, the provided benefit is a quick way to re-open records they have recently modified or created.
The part I'm having trouble handling is what happens when the user clicks the LinkButton, which is that the child page adds a new reference to the URL at the beginning of the List<> collection and I cannot seem to control the behavior of removing the LinkButton before it gets re-created. What I've tried doing is:
While that should work, my CreateBreadCrumb(string url, string title) function gets called by the child page before the UserControl detects the Repeater1_ItemCommand event, so in effect it appears that the wrong ItemIndex is being used for removal.
With following code, I can fetch all properties of user control. I need to get only those properties which were separately defined excluding the default ones.
I have created a user control and am ready to convert it into a custom control. I am trying to follow:
[URL] the steps mentioned in the link.
I am not seeing Build / Publish Web Site option.
I am using VS 2008. I only see Publish User Control but it doesn't give all the settings mentioned below. When I do publish user control, it just copies the ascx file to the desired location. how can I convert the user control to custom control.
This control may contain some other web server controls such as GridView.I need explanation of experienced developers, how to do that - take me to the right way
I'm new to all of this, so go easy on me. This should be an easy one. I have created a custom SmartContentBlock user control for a CMS.The control works, but only if I invoke the Fill() function in the Page_init event in the codebehind of the ASPX page. My goal is to modify the class file so that the Fill() in the codebehind is no longer neccesary. So, for reference, here's the gist of the current situtation.Controls.cs
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.
