Creating A Web Server Control That Has An Image Button On It?
Jun 7, 2010
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'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:
[Code]....
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 would like to know if the normal procedure for creating text files would work the same on a mobile website?
1. I would like a text file created on the server (not users pc) when user clicks a button on the web page. 2. How do I refresh an image every few seconds, only the image not the whole page.
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 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
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.
i'm developing a webusercontrol, that has very properties, properties are of custome types (not primitive), so i want user can edit properties in grid property. i want something like gridview here is a portion of my code:
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 am creating new custom command button control derived from asp.net command button. In my custom control I want to set two images (i.e. one from left and one from right). In center command text will come. I tried background image property using css. But I won't work out for me. The image is coming left but the actual command button style is lost and the second problem is I could not able to set image on right side.
I am knew to CSS I never usually do it. I am creating a menu and I change the image of the button when the button is hovered over it. But when I go on the submenu the image reverts back to the original image. The code I have used is below.
