Registering A Composite Control?
Dec 13, 2010
I am learning custom controls and just finished my first one. The problem is that I am struggling to register it in my web config and have the compiler recognize it. Right now this results in a YSOD about the reference to the control.
note: exact error - Error Unknown server tag 'cc:LblTextBox'.
Web Config
//..
//..
<pages>
<controls>
<add tagPrefix="cc" namespace="Controls.Server"/>
</controls>
</pages>
</system.web>
The control code-behind
namespace Controls.Server
{
public class LblTextBox : CompositeControl
{
//...
}
}

in my implementation, I have an interface as: ICachingManager. I've got now one implementation. I also created a manager class as:
public class CachingManager
{
#region Members
private ICachingManager service;
[Code]....
In case I had one implementation, then I can easily register the CachingManager class with Unity, automatically Unity resolves and injects the ICachingManager.
In case I had more than one implementation using named types, then how can I can make use of Unity? Do I need to make use of an Abstract Factory to decide on which named type to initialize?
Is it a good idea to make use of such a composite class or use directly implementations of the interface with Abstract Factory?

I have a ASP.Net project that is setup in such a way that it can be dropped into any site and "just work." All the paths are relative to the current file, not relative to the "~". The paths are determined by ThePath = this.TemplateSourceDirectory;
This is working for everything expect registering a custom control that is created and added to one of the pages. I can add the control just fine with the Page.LoadControl but I cant cast it as the correct type to access anything.
How can I add a reference to the class from within the code itself?

I have a page without codebehind where a control being registered via the following declaration:
<%@ Register TagPrefix="IBS" TagName="Schedule" Src="Schedule.ascx" %>
Then there is the following code:
[Code]....
And the page is working without any problems. I am trying to move the code to codebehind and as soon as I do it I get an error "Type 'Schedule_ascx' is not defined". What could be the problem?

I am trying to included a rating control in a composite control that renders many different type of controls. I render the controls by overriding the rendercontents so that I can control the layout of the controls. When I try to add the rating control to the output i get a Page cannot be null error. Can someone provide me with the proper way to render a rating control from a composite control and be able to control the layout of the child controls.

i create a composite control as can be seen in code below, and add this control to webform, assign FormView1 to the HeaderControlName property, Run the page, the system will generate parse error message :
Cannot create an object of type 'System.Web.UI.WebControls.FormView' from its string representation 'FormView1' for the 'HeaderControlName' property. However, if i don't assign FormView1 in design screen and manually (through coding) assign FormView1 to the custom control on init, it works as expected.
custom control
public class CmdTest : CompositeControl
{
public virtual FormView HeaderControlName
{
get
{
object oObject = ViewState["HeaderControlName"];
return (oObject == null) ? null : (FormView)oObject;
}
set
{
ViewState["HeaderControlName"] = value;
}
}
protected override void CreateChildControls(
{
Controls.Clear();
Button xx = new Button();
Controls.Add(xx);
}
}
webpage.aspx (assign FormView1 in design time, it will generate error)
<Utils:CmdTest ID="CmdTest1" runat="server" HeaderControlName="FormView1" />
webpage.aspx (didn't assign FormView1 in ASPX, but assign it on Init Code, it works)
<Utils:CmdTest ID="CmdTest1" runat="server" oninit="CmdTest1_Init" />
Webpage.aspx.cs
protected void BsCmdTest1_Init(object sender, EventArgs e)
{
CmdTest1.HeaderControlName = FormView1;
}

I have a custom control that renders different controls based on a property value. This all works correctly until i try and add a rating control to the control. When i render both controls in the CreateChildControls the control is rendered properly.
However when i try to add layout by overriding the RenderContents method and rendering controls there, an error is generated
Extender controls may not be registered after PreRender.The code shows both methods of creating the controls.

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 want to enhance a composite control's client side, my approach is to recreate all method on JavaScript, so here I have some troubles :
1) Can I call onclick event on client side otherwise on server side ?
2) the statement table.onclick=SelectRow(event) fires a bug !

Can anybody tell me how can i access ScriptManager in my Composite Control?
I do have reference of system.web in my project but when i type System.Web.UI.
i am not able to get reference of ScriptManager afeter UI.
The reason for doing this is that i have a composite control which is registering some client script on OnPreRender event.
this control works fine when placed on web page without update panel but gives error "object expected" when placed in an update panel
i am registering client script as follows

I have a composite control that has a couple of private fields that reference values in the cache and these private fields are called during the constructor method. Since a string key is used to identify the value in the cache, I must have a way of storing that string key in such a way that it is available at the time the control is instantiated, and I have to be able to reference it on postbacks without it changing.
In addition, this key is generated the first time the control is loaded, but it should not be changed again after that first time.
How can I accomplish this?
I have already tried saving it to viewstate, but that doesn't work because viewstate is not yet available at the time the control is instantiated.
I have tried using a private field and then checking against Page.IsPostback in the constructor and if it isn't postback, I assign a value to the private field, but on subsequent postbacks it looses it's value, and I can't reassign it in the Page.IsPostBack again because it is an autogenerated GUID.

In our current ASP.Net Webforms application we have several composite/template server controls that only exist for a common look and feel. For example, we have a panel control that has a title, a place for buttons related to the contents of the panel, and of course the contents. How is this best accomplished in MVC? RenderPartial doesn't get done what I need here. Should I still be using the same controls, but just on a view page? These controls don't really do anything on postback, they are only there for a common look and feel.
More Info:
We have a control in Webforms that implements ICompositeControl. We have a few properties on this control like Panel (type Panel), Buttons (again type Panel which would hold buttons) and a property Title of type string. Visually it looks like

I am trying to make a simple composite control - just a label and textbox - but the postback isn't being picked up by the control.I haven't implemented IPostBackDataHandler as according to this its not necessary - the TextBox control should tie in automagically. A composite control that includes a TextBox need not worry about postbacks, as the embedded control will work it out with ASP.NET automatically.
class TestControl : WebControl
{
Label _label;

I want to develop composite control where some of the work would be executed on client side. For that I am implementing IScriptControl.
ScriptReference points to a script file with client object.
Let's say I want it to have Listview(html select) control that onselect will run javascript function based on the selected value.
I can't just create the control dynamically is client js, because the control has UI on design mode so I must create the select control on server side (I create it in override void Render)
My problem how and where to assign the onselect event for the selection.
Update: Maybe I should add select's id as property to ScriptControlDescriptor, then in client control retrieve this id and attach the needed handler to the event?

I have got a composite control and i would like to dictate which attribute/property is assigned to the control first from the markup?example in the aspx file:
<MM:MyControl ID="" runat="server" ViewType="normal" BaseType="RealBase"></MM:MyControl>
when the control gets created from the mark-up above, ViewType will be assigned first, Which is what I do not want, I would like RealBase to be assigned first under all circumstances. This control is to be users by other developers so I cannot just switch the order.

I am designing an ASP.NET v3.5 custom control based on CompositeControl.
However, I do NOT want to create my child controls via code, but rather as
embedded HTML tag elements within the CompositeControl in the ASPX page, such as:
[code]....
At run time, MyControl.Controls contains the two labels as expected.
At design time, MyControl.Controls is empty.
I need this information at design time for various reasons.
What am I doing wrong?

I am building a composite server control that currently only has a TextBox and a DropDownList. Here is the code in all its foetal glory:
[Code]....
The control appears to work correctly across postbacks, that is until declarative values are set, e.g.:
<squee:Address runat="server" ID="a" Street="123 Fake St" State="VIC" />
After this, the text box continues to work correctly, but the _state member does not pick up the posted back values and instead just sticks to the declared value. I've checked the raw posted values in the Request object, and the new value for the list's UniqueID is there, but _state doesn't pick it up.

The question is in the title but to make it clearer when you use a normal server control like
<asp:textbox />
<CC1:CtrlArticleList SortBy="Title" ID="compositeControlArticleList" runat="server" />
the properties of textbox allow you to select from a dropdown list (eg visibility=...true or false). How do I replicate this in composite control?
Added code since question asked:
