Custom Control Properties Not Initializing Properly
Dec 14, 2010
The First - LblTextBox:
A label and textbox that have a LabelText field that can be set to change the label text
The Second - LoginCtl:
A login control that has two instances of LblTextBox for user name, password and a submit button
I want to control the tag rendering of these controls for formatting so I am not overriding CreateChildControls() to get the job done.
My issue is that the controls are rendered but none of the OnInit() code in either controls takes hold (blank labels, css styles not applied, etc..).

I have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.
Is there a way for the user to set that variable in the properties window after they drag the control onto a form.
I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.
Right now, I have to create the control dynamically. I read the query string and then created the object.

I have made a composite control that has 1 Label Control ,1 TextBox ,1 button and 1 Panel Control. Below is my code:
namespace ServerControl1
{
[
AspNetHostingPermission(SecurityAction.Demand,[code]....
The above code compiles without any error. Also I can drag and drop this control from the Toolbox of my Project on my web form. However I am unable the change the value of my fromLabel control.It allows me to change the value in the properties window.But when I run the form it always shows me its default value which is "From". I want it to be flexible so that any one can change the value in the properties window.

I have developed a ASP.Net Server custom control in C# for 3.5. named "myCheckBoxList" inherited from CheckBoxList web control. Working is very simple. It just works as a two option buttons. I have taken a CheckBoxList which will show two fixed checkboxes always. When I check one checkbox then another will uncheck as vise versa. This control works perfectly only when I have placed only one instance of that control on web page. If I place more than one instance of control then it doesnt works.
I need solution from expert minds from developers as stackoverflow users.

How can I add custom properties into control objects in ExtJs.
For example :
[code]....
This control comes from server dynamically and I want to write my custom property as well like below :

I tried it but it said undefined. Normally since JavaScript is loose, I can easily modify objects but in this case it wouldn't work the way I expected.

As a starting point for creating custom controls, I would like to make a control that simply displays a number. If we imagine the .ascx file contains nothing except for a literal control, and the code behind sets that value to 1.
I then want to be able to do myControl.increment();
This will run some javascript that increases the value of the literal control.
I could inject a javascript into the page, such as pseudocode:
page_load
{
scriptything.register("function increment(x) { $('#myLiteral').increment(); });
}
or something, but that wouldn't be myControl.increment, that would just be increment(). More than one control on the page would screw it up.

I've been working on this project for a few days now, and have been unable to resolve the issue of getting intellisense support for my custom-defined inner properties for a user control (ascx, mind you). I have seen the solution to this (using server controls, .cs mind you) many times. Spelled out in this article very well. Everything works for me while using ascx controls except intellisense. Here's the outline of my code:
[PersistChildren(true)]
[ParseChildren(typeof(BreadCrumbItem))]
[ControlBuilder(typeof(BreadCrumbItem))]
public partial class styledcontrols_buttons_BreadCrumb : System.Web.UI.UserControl
{
...
[PersistenceMode(PersistenceMode.InnerDefaultProperty)]
public List<BreadCrumbItem> BreadCrumbItems
{
get { return _breadCrumbItems; }
set { _breadCrumbItems = value; }
}
...
protected override void AddParsedSubObject(object obj)
{
base.AddParsedSubObject(obj);
if (obj is BreadCrumbItem)
BreadCrumbItems.Add(obj as BreadCrumbItem);
}
...
public class BreadCrumbItem : ControlBuilder
{
public string Text { get; set; }
public string NavigateURL { get; set; }
public override Type GetChildControlType(string tagName, System.Collections.IDictionary attribs)
{
if (String.Compare(tagName, "BreadCrumbItem", true) == 0)
{
return typeof(BreadCrumbItem);
}
return null;
}
}
}
Here's my mark up (which works fine, just no intellisense on the child object declarations):
<%@ Register src="../styledcontrols/buttons/BreadCrumb.ascx" tagname="BreadCrumb" tagprefix="uc1" %>
...
<uc1:BreadCrumb ID="BreadCrumb1" runat="server" BreadCrumbTitleText="Current Page">
<BreadCrumbItem Text="Home Page" NavigateURL="~/test/breadcrumbtest.aspx?iwentsomewhere=1" />
<BreadCrumbItem Text="Secondary Page" NavigateURL="~/test/breadcrumbtest.aspx?iwentsomewhere=1" />
</uc1:BreadCrumb>
I think the issue lies with how the intellisense engine traverses supporting classes. All the working examples I see of this are not ascx, but Web Server Controls (cs, in a compiled assembly).

I have a C#/ASP.NET .aspx page that declares two controls that each represents the content of one tab. I want a query string argument (e.g., ?tab=1) to determine which of the two controls is activated. My problem is, they both go through the initialization events and populate their child controls, wasting CPU resources and slowing the response time. Is it possible to deactivate them somehow so they don't go through any initialization?
My .aspx page looks like this:
<% if (TabId == 0)
{ %>
<my:usercontroltabone id="ctrl1" runat="server" />
<% }
else if (TabId == 1)
{ %>
<my:usercontroltabtwo id="ctrl2" runat="server" />
<% } %>
I assumed the that <%'s would have meant the control wouldn't actually be declared and so wouldn't initialize, but that isn't so...

I am writing a custom composite WebControl and want to expose styles of child controls it encapsulates to the ASP.NET designer. The code I currently have is similar to the skeleton below (which for simplicity only has one child control).
With the code below, I can see property "ChildPanelStyle" in the designer, but when I try to modify one of the properties (e.g. CssClass) in the designer, it immediately resets itself to its default value. It looks like the designer serialization isn't happening.
What am I doing wrong?
UPDATE
I've updated the sample with an additional style property that is managed directly by the custom control, rather than simply being the property of a child control.
The HeaderStyle property is persisted properly by the designer, but the ChildPanelStyle property isn't.
Of course I could manage all my styles like HeaderStyle, and apply them during rendering, but I'm hoping there's a simpler solution whereby child controls can take care of themselves, and I don't need any custom rendering.

I would like to ask you what is the best practice for developing composite user web control with multiple controls inside from the stand point of dealing with properieties. In my situation I would like to use header menu bar with logos, buttons, java baset visible/hidden menus itc as web control. I was successfull in implementing new control in my project.
But my question goes to issue of properties for ALL OF controls. I know how to hard code all required properties like: text, visible, enable for all controls. It's a lot of work. ( This is the very edge of my asp.net comprehension ) Is there a more elegant way provide an access to controls's properties without hard coding seperatelly?

I can load a generic user control just fine in my WCF service doing the following:
UserControl userControl= (UserControl) new Page().LoadControl("~/UserControls/MyControl.ascx");
However i can't seem to find any way to do this
MyControl myControl=(MyControl)userControl;
The reason i need to do this is because my user control has a custom property, person, I need to do the following:
myControl.Person=new Person();
essentially i need to simulate:
<%@ Reference Control="~/UserControls/MyControl.ascx" %>
which normally goes inside asp.net page or master-pages.any way of doing this in an Ajax Enabled WCF Service?

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?

If the answer to this question exists somewhere, I'm no good at searching for it. This is sort of a simple question, the response being two parts: (1) is it possible? (2) if so, how?
I've created a web user control for my site's footer. In my web.config I have it registered like this:
[Code]....
Then, within the pages on my site, I simply insert it like this:
[Code]....
But obviously, that didn't work. I get this error: The type or namespace name 'FooterControl' could not be found (are you missing a using directive or an assembly reference?)
So I'm really not sure what to do at this point. I can put all of my code in the ASPX file and make my life easier, but I would kind of prefer not to.

I have a custom server control inheriting from CompositeControl. It consists of two RadioButtonlist controls that are rendered side by side in an html table. The number of ListItems in each RadioButtonList is not known until runtime. Depending on how many items each list contains, the RepeatColumns property of each list is set differently. To do this in the handler for the ItemDataBound event I need to get the count of ListItems in each RadioButtonList. How do I expose the Items.Count property of each internal RadioButtonList as a top-level property? I tried using a getter to return the count but this generates a compile-time error to the effect that the count cannot be assigned to--even though I have not created a setter.
Similarly, in the handler for the Submit event, I need to get the ClientID of each internal RadioButtonList to pass to a method that checks for data changes. How do I expose the ClientID of each component RadioButtonList as a top-level property?
I can of course index the Controls collection of the composite control to access the child control and read its properties--but that defeats the whole point of making a complex, independent custom server control.

I have this custom error redirect in my web.config file but it doesn't seem to be working since i added the redirectMode="ResponseRewrite"
It works fine for 500 errors but not for 404 (it just doesn't redirect when i have a 404)
Here's the code from web.config
<customErrors mode="On" redirectMode="ResponseRewrite">
<error statusCode="404" redirect="/servererror/default.aspx" />
<error statusCode="500" redirect="/servererror/default.aspx" />
</customErrors>
[Code]....
I need to keep the redirectMode="ResponseRewrite" so that the servererror/default.aspx sends me an e-mail when there's an error

I am creating a custom server control (derived from WebControl).
In RenderContents(HtmlTextWriter), I must use HtmlTextWriter.Indent to manipulate indentations.
Unfortunately, this property always starts with zero so it breaks the indentation from the host/parent control.
My question is, how to know the last indent value of the parent tag that contains my custom server control?

I've managed to render TreeView using custom made Hierarchical Datasource based on Linq queries on self referencing table. Rendered output looks well but... Every Node in NodeCollection has the same index = 0. Therefore when I click on any collapse button - the whole tree Collapses. In generated html every node has the same id = MainContent_TreeView1n0 I suppose n0 should increment to n1 n2 n3 and so on.
