Custom Server Controls :: Attributes For The First <li> Element Is Not Rendered
Aug 2, 2010
I'm working on a custom serverside control and faced to a weird issue.
The control's client-side markup should look like:
[Code]....
But my control renders following markup:
[Code]....
As you can see, attributes for the first <li> element is not rendered.
Here's the Render method:
[Code]....
items collection is filled correctly. Debugging the code showed that AddAttribute is called for first Li element, but the output is rendered incorrectly.

public class CustCtl : WebControl
{
protected override System.Web.UI.HtmlTextWriterTag TagKey
{
get
{
return HtmlTextWriterTag.Div;
}
}
}
With this bare bones control, it would render the root element as a Div tag. But how can I add attributes to that root HTML element that this control will render .

I have created a custom control and I intended to assign some attributes which is not necessary to implament.
I also assign default value for them but I am getting System.NullReferenceException error.
Here is my CC's attibute code;
public class ApplicationModule2010 : CompositeControl
{
[DefaultValue(true)]
public bool AppFormOnLine { get { return (bool)ViewState["AppFormOnLine"]; } set { ViewState["AppFormOnLine"] = value; } }
...
also ı have written the below code for another attribute but its default value doesn't work as well;
[DefaultValue("Application is Offline ! Define an offline Text insted of this text !<br/><br/>TugberkUgurlu.Com")]
public string OfflineText { get { return (string)ViewState["OfflineText"]; } set { ViewState["OfflineText"] = value; } }
What am I missing here ?

You're making a website with ASP.NET 4.0/C#, although xml alone is suitable for this example. The site will have a site map and a default page with a menu control, as follows:Web.sitemap
<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode url="~/default.aspx" title="Home" description="">
<siteMapNode url="~/1.aspx" title="Link 1" description="" />
<siteMapNode url="~/2.aspx" title="Link 2" description="" />
<siteMapNode url="~/3.aspx" title="Link 3" description="" />

I have a custom control that renders a button. I'm trying to attach a server click event but it isn't firing. My code is:
protected override void CreateChildControls()
{
btnRangeGo = new Button();
btnRangeGo.CssClass = "divSearchGo";
btnRangeGo.Text = Resources.CORE_Resource.S0C29; // Go
btnRangeGo.Click += new EventHandler(btnRangeGo_Click);
// Tried with no luck:
// this.Controls.Add(btnRangeGo); // Needed so OnClick gets registered
// Page.Controls.Add(btnRangeGo); // Needed so OnClick gets registered
}
private void btnRangeGo_Click(object sender, EventArgs e)
{
int i = 1;
}
OnRender:
btnRangeGo.RenderControl(writer);

I have a MyLinkButton : LinkButton.
In any event I override I don't have any attributes in my "base.Attributes or this.Attributes" collection. How's that possible? The rendered output clearly shows an id and an href attribute.
I'm trying to get rid of the href part and put in my own. Unfortunately Attributes.Remove("href") won't work.. because there's no such attribute. Or any attribute for that matter.

I have a simple user control which is nothing but a simple input field with runat="server":
<input id="mySimpleTextBox" type="text" runat="server"/>
My observation so far in the output rendered by a datalist (when I use this user control inside it) is that the value for the name attribute is the same.I want to use this control inside a datalist/repeater such that I'd want a unique value for the input element's name attribute when the datalist/repeater renders. How is this done?
EDIT: My bad obversation. Actually the names are unique. However, when I try to post the page to another web page which outputs the key & value of all the items in Request.Form I don't see the input elements...

I have a web form with usual elements (first name, last name, etc). The Postback URL is a different website altogether as the form is intented to post lead information to another website.
The site that accepts the lead is expecting First Name to come over as "FName", and Last Name to come over as "LName". Is there any way I can set the ID of a textbox to "txtFName", but submit it over the wire as "FName"? I tried changing the name attribute, but at runtime it sets the name = id.

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.

Is there a way to add custom attributes to @Page directive and also get design time support like intellisense for the same?
I have used Adding Custom Property to Page Directive in ASP.Net 2.0 as a pointer.
I would like to have a attribute which will give dev an option to select value from list. Something similar to EnableSessionState attribute. I do understand I need to define an enum for the values. But I cannot understand how to make it available during the design time.

I am trying to build a custom composite control, which allows me to add custom content to each child control. It's a similar concept to what you have with a GridView and TemplateColumn. The markup used to place the control on the page would end up being something like this:
[Code]....
I have the code below, which allows me to put that markup on the page without throwing any errors, and it renders all the correct HTML, except it doesn't render the contents of the ColumnTemplate. I have replaced the Render() code with a comment because it's quite long winded and doesn't add anything important here:
[Code]....
I have tried to follow examples on MSDN and other forums but I can't make this work. I think I'm missing the code to render the contents of the template, but I don't know how to hook that up.

I want to add a custom attribute to an asp.net RadioButton called Key which I'm using client-side for an ajax request.
What I'm finding is that my aspx markup which is the following:
<asp:RadioButton ID="rdoPost" GroupName=PreferredContactMethod" value="Post" onclick="DoStuff(this)" runat="server" />
gets rendered in the page as<span Key="ContactMethod">
<input id="rdoPost" type="radio" name="PreferredContactMethod"" value="Post" onclick="DoStuff(this);" />
</span>
whereas I'd expected (and hoped) to get the following
<input id="rdoPost" type="radio" Key="ContactMethod" name="PreferredContactMethod"" value="Post" onclick="DoStuff(this);" />
I've tried the same thing with an asp TextBox control and it works exactly as I'd expect simply adding the Key="myKey" attribute to the <input type="text"/> element.Is there a way around this with the standard RadioButton control, or will I have to inherit from the standard one to achieve the markup I'm wanting? Currently I'm using these attributes in JavaScript in the following way:
var key = rdoPost.Key;

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.*")>
