JavaScript - How To Create Custom Controls Dynamically
Oct 18, 2010
I want to create custom control (let's name it DesignPanel) that will allow user to design his own webpage structure that would be stored in a sitemap file. This Design Panel will have child controls inside ( SiteElement). User will build page strcture by connect Site Elements, customize them ( like change name) and add new ones.
This last point is main issue for me. Should I add those Site Element controls dynamically like DesignPanel.Controls.Add(new SiteElement()) in UpdatePanel control or there is better approach ( adding them to DOM structure by javascript, something diffrent)?

I am trying to create a composite control - A textbox, gridview and a button. When I create the grid dynamically, I use my function GridViewDataBind() that will basically create the gridview at runtime and bind it with data. In this method, I add a blank column (first column for expand/collapse image), databound columns (using custom Itemtemplate), a placeholder, then a new html row/cell and a child gridview. I want to know how can I add these html rows/cols to my gridview. Here is the code:

Not sure if the approach is right and if I was able to explain my problem?

I'm new to .NET. I'm trying to create a button dynamically with event by original button. The original button's click event response creates a button. The new button has a click event attached with a test message.What I have to do is onclick change background color of dynamically created button and grab id value to delete when button delete is clicked. Unfortunately, when I click the dynamically attached button, nothing happens.

I need to create a table with just 1 column containing times (starting from 4hrs) which increase in increments of 10 seconds for each row. So it needs to look something like this:
04hrs 00mins 00secs - 04hrs 00mins 09secs
04hrs 00mins 10secs - 04hrs 00mins 19secs
04hrs 00mins 20secs - 04hrs 00mins 29secs
.....
06hrs 59mins 50secs - 06hrs 59mins 59secs
This will obviously take a long long time to hard code so I'm looking to create it dynamically. Based on what i'm currently trying to learn I'd like to be able to do this using jquery or asp.net (vb) but anything will do as long as it works!

I want to create a custom control where I define several specifically named DIV sections. The code-behind logic of the custom control will perform operations on these named DIV sections. The page where the custom control is hosted needs to be able to add named controls to the DIV sections and perform operations on these named controls added to the DIV sections.
Let me explain a little further. In the custom control, I want to have code behind logic that fires the following Page Event and uses a condition to make one or another specifically named DIV section visible or not:
< _
ToolboxData("<{0}:BaseDetails runat=""server""></{0}:BaseDetails>") _
> _
Public Class BaseDetails
[code]...
how can I create a custom control which is able to generate the named DIV sections "DetailsNameDiv1" and "DetailsNameDiv2" where my custom control can check a condition and make one or the other visible. Also, I need to be able to add controls to these named DIV sections when I host the custom control and the control that I add to the named DIV section needs to let me set values of these controls from the code behind logic of the page (or usercontrol) where the custom control is being hosted (in my example, I am adding TextBox controls that I want to set the Text property from a SQL Data Reader).

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:
<Assembly: AssemblyVersion("1.0.*")>

I am going to create some custom controls to use them in different projects. Therefore I found some helpful content on microsoft's support sites. These again dealt with overriding the html-render-method, but I am still wondering if this is the most elegant way, because in my opinion this just means outsourcing of some code from the view to the class file.Do I misunderstand the way of how custom controls should be used?

First, I would like to apologize, the search on the site wasn't working, so I don't know if I'm missing an existing post or not.
I have a web page that uses a master page file. I am using a third party control from Component One(TabStrip), the tabs are rendered as links on the final page. When a tab(link) is clicked, I need to load the appropriate web user control associated with that tab. Each web user control has its own post backs and methods. I know that I can load the controls on the "SelectionChanged" event of the TabStrip control, but then any postback created by the web user control that is loaded causes the page to refresh and the control was never loaded in viewstate. So, I tried to put my procedure of loading the web user control into the page_init method. This would work, if I could read which link was clicked on from within the page_init method. I tried using a javascript function to run "onclick" of the tabs and within it setting the value of a hidden control. I have verified that the javascript works and that the hidden control's value is getting set correctly. When I get into the page_init method, the value of the hidden control is not readable.
I'm tying to understand the page lifecycle to the fullest, but I don't see what I'm missing here. I know that I need to load the web user controls in the page_init method in order to persist the page as a whole, but how can I get which tab(link) was clicked to know which control should be loaded?

For test purposes I have created a simple button control that extends CompositeControl. I am able to place it on the page with a <asp:Content... and the Click event Bubbles without problem from the Control.
Now, here is the problem I am facing Due to design requirement I need to read the assembly and the classname from a table and dynamically create the control and add it to the <asp:Content. And when I do that the click event will not fire! Where am I going wrong.
Here is the code in the ButtonControl.cs
namespace Reports.Web.ServerControls {
[DefaultProperty("Text")]
[ToolboxData("<{0}:ButtonControl runat=server></{0}:ButtonControl>")]
public class ButtonControl : CompositeControl {
protected override void CreateChildControls() {
Button btn = new Button();

In ASP.Net I have a few custom controls I've made. I utilized jQuery where it helped also. Well, one problem I have now(with obvious, but "bad" workarounds) is that for each user control I need to execute some code from within pageLoad($(document).ready will not work with update panels). Well so now my problem. I need to have two custom controls attach to the pageLoad event. What would be the best way of doing this? I can't just do
old_pageLoad=pageLoad
pageLoad=function(){... old_pageLoad();}
because these custom controls can be used more than once on a page and the script needs to run for every single instance of the control, plus what if I had 3 different custom controls on the page? the only method I've come up with is something like this which seems super hackish:
old_pageLoad_<%= MyStaticClass.GetUniqueID() %>=pageLoad;
pageLoad=function(){... old_pageLoad_<%= MyStaticClass.GetUniqueID() %>();}
Are there any better ways of handling function conflicts like this? I have also seen this MSDN article but what it suggests doing seems worse to me than what I am currently doing.

I have a composite user control consisting of three standard table cells (a legend, an image with a tool tip, and a text field control). If I add these to a TableRow in my aspx page it works fine and produces legal HTML in my source. The below works fine ...
<tr><MyControl:dataField
ID="txtEmail"
DataType="Email"
runat="server"
/></tr>
However when I try to do the same programmatically (C#) the TableRow won't accept anything in its Controls collection that isn't a TableCell. I could make my control a nested table in its own right but I lose the alignment of my form items on the page with multiple controls, as each table aligns itself according to its contents. Is there anyway I can make the TableRow accept my control as collection of cells or do I need to do some casting or making my user control inherit some kind of TableCell attributes? I can also dynamically add my controls to a TableCell item which actually displays OK in IE but creates illegal HTML (<td><td></td><td> ... </td></td> - I assume this is illegal) in my resulting source. The code below DOES NOT work ...

I try several ways to create a few control in an .aspx page's code-behind. I have these problems:
1) name of each component
2) place of these components
3) access to these components in method event or totally in code behind
I want to create a few <asp:textbox> and put them in table rows. I'd like to then get value of these textboxes and do somthing with them.

i have been trying to create controls dynamically on my web page using the StringBuilder class..and i dont quite seem to get through...
i am trying to do this...
StringBuilder sbTest = new StringBuilder(string.Empty);
sbTest.Append("<input type="text" id="txt1" runat="server" />");
Response.Write(sbTest.ToString());
The page for sure displays a TextBox on the browser which is easily accessible through JavaScript...but what i want is the control to be available on the Server Side too...so that when the page is posted back to the server i can easliy obtain the value that has been entered by the user into the textbox.
