C# - Create ChildControls With Custom Control?
Sep 23, 2010
I have a custom control that creates a textbox on CreateChildControls.I'm trying to set the value of this textbox (trough a property of the control) on the load event of the page that uses the custom control. Unfortunately at this point CreateChildControls haven't been executed yet and the textbox is null.
I called EnsureChildControls on the consumer page before using the custom control properties but no luck, still null.This happens when is not postback.

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 have currently on multiple pages a modal popup that displays the information below, we are getting to the point where we need to call this popup from multiple locations, currently i have duplicate setups on each page that i want to use it on, but its becoming a mess to manage when a change is needed.. so im looking to see if what i have within the modal popup can be turned into a control that i can call anywhere thru out the site and have just 1 setup to maintain going forward..If its possible to create a control that can then be placed within the modal popup and server the same purpose that would be great any links here is what i have within the modal popup that i have on atleast 3 pages currently..

I have created a custom web control. In that control on CreateChildControls method i dynamically create a Table add rows to it which contains a ImageButton and i am trying to attach an event to this ImageButton but the event never fires?
I tried on Init method too it does not work . The code goes like this on CreateChildControls
I create a Panel . The i create a table with data and an imagebutton on it I add this table to the created panel I add this Panel to the Controls.Add method.
I have also observed that if i add a control directly to the Controls.Add() method and attach an event it works fine .
Meaning ,
1. Create a button attach an event handler
2. Add to the Controls.Add() method
On doing the above it works fine . Only the child controls events do not get fired is there anything that i am missing ??

I want to created a Custom Server Control (Inherited from GridView).
On the page, the GridView is DataBound to a DataSet, so I do not know at design time what columns will be present in my GridView.
Now, what I want to do is, to add a textbox in every Cell for the GridView Header row, and those textboxes will control column filtering.

I want a create a custom/user control that has children.
For Example, I want my control to have the following markup:
<div runat="server" id="div">
<label runat="server" id="label"></label>
<div class="field">
<!-- INSERT CHILDREN HERE -->
</div>
</div>
and when I want to use it on a page I simply:
<ctr:MyUserControl runat="server" ID="myControl">
<span>This is a child</span>
<div runat="server" id="myChild">And another <b>child</b>
</ctr:MyUserControl>
The child controls inside my user control will be inserted into my user control somewhere. What is the best way to accomplish this?
The functionality is similar to a asp:PlaceHolder but I want to add a couple more options as well as additional markup and the such. Also the child controls still need to be able to be accessed by the page. (in the example above the page should have the myChild Control on it)
EDIT ------
It can be a template control as long as it allows me to reference the children on the page.

I am trying to figure out how to use/create a custom control in ASP.NET MVC 2.
I created a custom control earlier and compiled it (ccontrol.dll), the control renders a div, textbox and a button + some javascript in order to post a comment on the website. It could be a static aspx page that i wanted to allow my visitors to add a comment to. I would then drag my control from the toolbar to the aspx page and run it, it would then render all the code needed on the webpage including fetching the data from a datasource and displaying that inside the div. The user could also just type in a comment and press the button to save it to the datasource.
Is this possible to convert to MVC 2? Any good tutorial that covers custom controls and MVC 2? (Ideally would be if the control could be made into a .dll file that i then could reuse on future webpages)
How do i write a custom control the mvc way? Any good tutorials on the topic?

I am searching already the web for some hours to get this working. I created a custom control (ConfigTree), which has a treeview as part of it. I put the custom control into an update panel. So far so good. When I click on different buttons (in ucc:ConfigTree) or the treeview in the custom control an async postback is done. When clicking on a node in the treeview an event for the parent element (ConfigTree) is generated, which populates again an event (NodeSelected) for the parent element (shown below). Different parent elements can handle the event differently. In one element (this one) I need to transform the async postback in a real postback with full page refresh. For better understanding see the following code:
[Code]....
the parent element (here shown) should process the OnNodeSelected and transform it into an full postback and not just an async postback, but only this event, all the other events in the ucc:ConfigTree should processed async. How can I do that? Is there a method to call in the code behind?
