Custom Server Controls :: Looking For Pointers/advice For Creating This Control?
Jan 18, 2011
Within an existing ASP.NET page I've created the following layout, which is a tabbed header and content area. When the tabs are clicked (using JQuery) I show the relevant content, and hide all the other content for that respective tab, like so...
I'd like to expand this functionality to make it into a User Control, so that I could re-use the code more easily. Once the control is created, I'd like to be able to use it like this:[Code]....
where I can start learning how to do this, or offer direct help on the code? I've read many tutorials for creating controls using existing controls (e.g. custom labels etc) but they are all too simple. With the above, do I need to create a ContentArea control first, then work onto the TabbedControl? How do I get ASP.NET to render out the contents of my ContentArea (including ASP.NET controls that are contained within it)?

I'm a little stuck here, with my first server control. I'll just post the whole thing, as I'm sure I've done plenty of mistakes. The main thing for me to find out is if there's a more elegang way to write this.
What I'm trying to accomplish here is to write a panel with custom HTML inside it. Inside the custom HTML, I need to put some server controls I can actually reach. My attempt at finding the span in the code failed, so there's obviously something wrong.

Obviously, I've only just begun, but I'd really value some feedback before I dig myself in too deep ;)

I am creating a custom control by inheriting a server control, say LinkButton. There are properties like "BorderColor" available in LinkButton. Let's say, I don't want this particular property to be available when I create an instance of the custom control.
I want to completely hide this particular property (I don't want to override it but disable it.)
My code is as follows:

I want to create a map control which will be a server side control.I want to have it as a tool in the toolbox. The above control will contain providers that will fetch maps from the following sources:
1) WMS
2) Oracle Spatial DB
3) Google
4) MS Virtual earth.
How to create the providers for the different map sources? Then I hav to create different screens which will take the parameters and send them to the map preoviders. The map providers will send the generated map to a map control (could be a active X control) or something else. The map control should also be capable of performing standard functions like pan,zoom etc. Pls give some idea as well as source code on how to start with it.

I want to create a completely new control instead of extending an existing one. I have found a few articles on the net, but it's not exactly what I'm looking for. I've created Custom User controls in Win Forms before and thought it would be somewhat the same in ASP.NET, but it does not seem so. Many articles talk about a Web Control Library template which doesn't seem to be available when creating a New Project, but is available when adding a New item to an existing ASP.NET forms project in VS2008.
I have extended control by using the ASP.NET Server Control template. But all you get with is a .cs file. How do design a brand new control with that?What I want is to create a control from scratch, with postback functionality, and that compiles to a DLL. Am I going about this all wrong? Should I rather be looking at the ASP.NET Server Control Project Template? If so, How do I create a brand new control with the ASP.NET Server Control?I'm working with VS2008 SP1, .net 3.5, and C#.

I've been asked to upgrade a few applications and I'm planning on merging all of them into one asp.net application. I'm fine with this decision and have spoken with fellow workers and they also think it's the best option to go with.
The application will be accessed from a small group of users which belong to a larger domain. I'm currently planning on using Windows authentication and only allow this small set of users to access the asp.net application. Also there must be some role management, so that only certain users can view certain functionality.
I really don't want to have many different windows groups; so I want to avoid having to assign different windows groups to different folders and control permissions in the web.config.
What I'd like to do is:
- Assign one windows group to the small group of users who will access the page.
- Create a custom membership provider and control the user who accesses the application. Depending on the user I will then assign his current set of roles.
- Add an application setting to the web.config, with the name of the current administrator, so if he logs in, he will be assigned all roles, and will be able to create and assign roles to other users.

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.

here's a situation and I would appreciate your response.
I have programmatically created the Wizard control:
Page_Load(obj s, evargs e)
{
Wizard ClaimDetailWizard = new Wizard();
foreach(int item in selectedItems)
{
//create new step
//added custom control to new step
//add step to wizard
}
//added wizard to a placeholder on a page
}
Based on List I get from Session i added new steps to my wizard To each step I had added a custom control
Each custom control in tern contains another custom Gridview Control in it.
So here's the problem when the page loads for example for two steps. All is good Wizard does what it's supposed to do.
But when I try to use sorting or paging in that custom Gridview. Somehow it displays the gridview I should see in the next step of the wizard.
Also what I'm noticing through debugging. Is that when I press next in the wizard I go back to the original page where I do all of the code specified above, and it recreates the wizzard. But it goes to the next step. Is this the way wizard supposed to work? Just doesn't seem very efficient.

created a Custom Textbox Control that is intended to be a "masked date" textbox, so that I can handle different ways a user might enter in a date and make it work no matter what.I did this by creating a custom control with 3 separate Textboxes one for month,one for day one for year,then do some handling for different things that could be entered and it would all work.
The problem I am having is,when I add this control to the page,if I do an alert to check the Text value of the custom control it just gives me "[ServerControl1]" even if I enter in a date.
I tried doing an AutoPostback after entering so that it would refesh the Viewstate to have the values of the textboxes but the control doesnt seem to actually postback, even though I have it enabled.accessing the Textbox value after someoen
has entered a date?first custom control I have created and have been using google.

I am trying to build a custom composite control, which allows me to add custom content to each child control. It's a similar concept to what you have with a GridView and TemplateColumn. The markup used to place the control on the page would end up being something like this:
[Code]....
I have the code below, which allows me to put that markup on the page without throwing any errors, and it renders all the correct HTML, except it doesn't render the contents of the ColumnTemplate. I have replaced the Render() code with a comment because it's quite long winded and doesn't add anything important here:
[Code]....
I have tried to follow examples on MSDN and other forums but I can't make this work. I think I'm missing the code to render the contents of the template, but I don't know how to hook that up.

I need to develop control (template or user) which must have subtags with some items.
For example :
<SomeControl runat="server" id="scTest">
<column1>TestColumn1</column1>
<column1>TestColumn1</column1>
<column1>TestColumn1</column1>
</SomeControl>
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 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 a control that displays a list of comments. The comments are created in a loop. The problem is that I want to put a LinkButton at the end of each comment and change the CommanArgument of each button to the ID of the current comment.
When I put the Linkbutton in the CreateChildControls method and then add the CommandArgument in the Render loop, the button works, but the argument is blank. When I put the code that's in the CreateChildControls method inside of the loop, I don't get an error, but nothing happens when the button is clicked.
Below is the relevent code ...

I am creating a custom server control, and I am wanting to include a JavaScript file in the dll file when the control is built. I have tried suggestions from the following websites:[URL] But after following the directions, If I use firebug to see what errors show up, the JavaScript functions that are being called all say "goNext is not defined" which leads me to believe the JavaScript file is not being added correctly.
Some information on what my control looks like
I have the JavaScript File in a folder called Script. The namespace of the project is CustomControl, and the Name of the project is MaskedDateTextbox.
In my AssemblyInfo I have the following:
