Creating Server Control
Jan 24, 2013
I need to use radio buttons in a datarepeater. The problem is that radio buttons do not get the same ID in repeaters, so cannot be mutually exclusive. One way I read about getting around this is to create my own radio button and just render it differently.
I am trying to create a server control that inherits from the radio button. It needs to support postback and async post backs and have event handlers. The code I have works fine, in the sense each radio button is mutually exclusive but events are not being fired.server control:
Code:
<System.Security.Permissions.PermissionSetAttribute(System.Security.Permissions.SecurityAction.Demand, Name:="FullTrust")> Public Class NewRadioButton
Inherits System.Web.UI.WebControls.WebControl
Implements System.Web.UI.IPostBackEventHandler
[code]...

I am attempting to extract all of my reusable user/server controls from my web application and convert them into an external dll, but I'm running into tons of problems right from the start:Project type - Do I make an ASP.NET Web Application, or a Class Library?External references - How can I contain all external references within the dll itself, so that I can just copy + paste and Add Reference to just 1 DLL instead of 5 or 6?File types - Class Library projects are lacking certain options in the Add New Item window, such as asmx Web Services.

I'm creating a web server control that has an image button on it.The html for the control is done in the RenderControls of the code, the control devrives from WebControl, IScriptControl, INamingContainer.The button is coded as follow in the RenderControls:
System.Web.UI.WebControls.ImageButton img = new System.Web.UI.WebControls.ImageButton();
img.ImageUrl = "Url of the image";
img.Click += new ImageClickEventHandler(img_Click);
img.ID = this.ClientID + "_img";
img.CausesValidation = false;
imgLock.RenderControl(output);
The button apreas in the browser but when i click on it, the page postsback but the event handler for the button doesn't get fired, from what i can figure out, since the control goes throught RenderControls eachtime the page is posted back, the button gets redrawn and the event handling disapears.

I want to be able to do something like this
<test:TabControl id="" runat="server"....>
<ItemTemplate>
<tabItem label="tab1" />
<tabItem label="tab2" />
</ItemTemplate>
</test>
The idea being here is that the only acceptable items in "ItemTemplates" are the tabitem types. There are many asp.net controls that use this, for example the ScriptManager class only allows you to specify certain types of objects under its various collections. Maybe thats the key to this.. I want to add a collection as opposed to a template. The idea is that in code I will then iterate over each "tabItem" and create the tab as I want it to look (probably rendering div's etc). Ive had a look at most of MSDN link on how to create templated controls but it doesnt seem to do exactly what I want it to. Would be grateful for some assistance.

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.

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 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'm creating a web server control that has an image button on it in a table cell.The html for the server control is done in the RenderControls of the code, the server control devrives from WebControl, IScriptControl, INamingContainer and it is mostlly regular HTML with a few ASP.Net controls including the button.The button is coded as follow in the RenderControls:

The button apreas in any pages that uses the master page where the server control is used.When i click on it, the page postsback occures but the event handler for the button doesn't get fired, from what i can figure out, since the server control goes throught RenderControls each time the page is posted back, the button gets redrawn and the event handling disapears.

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:

We had a website deployed on IIS server remotely say www.liveserver.com.
We recently decided to make a copy of the website internal to the organisation so we brought a server and copied all the code from live server and configured it and say it is http//archives-testserver.com
Everything seems to work fine but while navigating and clicking on certain module links within http//archives-testserver.com......the domain name is getting rewritten to www.liveserver.com and user is made to navigate on the live site. I wonder where this
configuration is with in IIS...
I looked under properties under website identification and everything is referring it as http://arhives-testserver.com. also thr is a file called securityRedirect.inc and ifor handling errors and all the references have been changed and couldn't find anything in web.config. where else to look for probable reference to live site?

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 need to create a scheduling control in ASP.NET. Meeting slots are fixed to 30 minutes.
I am showing the slots in tabular format.
My main concern is to DateTime and slot timing like 4 to 4 4:30 to be read in code when user clicks particular cell in table, using HtmlTable control.
Table is created dynamically. Unfortunately the TableCell control don't have a click event.
In short, how can I detect the DateTime and timing from cell in the table by?

I recently downloaded Visual Web Developer Express 2010 and I am having difficulty with the report viewer control. I also downloaded the reportviewer 2010 redistibutable and added a reference to my site. When I drag and drop from the toolbox in design view the controls error is: Failed to create designer "Microsoft.Reporting.WebForms.ReportViewer, Microsoft.Reportviewer.WebForms, version=10.0.0.0 culture=neutral PublicKeyToken=b03f5f7f11d50a3a. It works when I view it in the browser and the report renders fine but I don't have access to it in design mode. Also, when I attempt to view a rdlc file it's the xml version instead of design mode.
I have a trial version of Visual Studio on another computer so I created a reportviewer website and opened this site with the Visual Web Developer Express 2010. The web.config relating to the reportviewer is below.Thanks in advance for your assistance. There isn't much on the web to fix this problem.
