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'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.
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 ?
I have implemented a custom ModelMetadataProvider so that I can decorate my view models with some custom attributes and everything was working fine until I made use of a Partial View. The following code in my view works fine: -
<%: Html.DisplayFor(x => x.Results) %>
Results is a List which renders a custom display template and is also decorated with a custom attribute. Using breakpoints, after the above line and prior to the code within the custom display template, the overridden CreateMetadata method in my custom ModelMetadataProvider is invoked. If I look at the attributes collection parameter I can see that it does contain my custom attribute thus everything working as expected. However, if I replace the above with the following line of code in my view then it breaks: -
<% Html.RenderPartial("ApplicationSearchResults", Model.Results, new ViewDataDictionary()); %>
All the Partial View contains is: -
<%: Html.DisplayFor(x => x) %>
Again using breakpoints, after the above line and prior to the code within the custom display template, the overridden CreateMetadata method in my custom ModelMetadataProvider is invoked. But this time if I look at the attributes collection parameter my custom attribute is not there.
I'm new to ASP.NET and MVC in particular. Now, I'm trying to understand if I can easily get values of custom attributes of submitted data. For example, When writing something like this inside a form (which works and posts and I can get the checkbox value) <%= Html.CheckBox("cb1", new { listen = "listen:6" }) %> Can I get the value of "listen" directly or do I need JS? (I know I can just use hidden fields, but I'm I'm asking anyway)
View 1 RepliesI 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;
For example:
<uc:AdmiralAckbar runat="server" id="myCustomControl">
<Warning SomeAttribute="It's A Trap">
My Data
</Warning>
</uc:AdmiralAckbar>
I'm not sure how to add SomeAttribute.
Code without the attribute is:

I am using DataAnnotations to supply information for Inserting/Editing data into a grid. Is there a way to control the Html attributes of the DisplayNames I use, so that, for instance, the DisplayNames can be a different color from the text in the textboxes?
View 1 RepliesI 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 user control that displays a list of records. Users have the ability to open an embedded user control with a FormView to either add a new record or to edit an existing one. The UserControl with the FormView has a button that closes and hides the user control.
If the user control with the FormView is opened to edit a record, the code works fine. But if the UserControl is opened directly into Insert mode, the code craps out

this.XXX.InnerHtml = "BBB";

}
I get an error when I refer to the id, "XXX" (underlined above) in code behind which reads: 'UserControls_test' does not contain a definition for 'XXX' and no extension method 'XXX' accepting a first argument of type 'UserControls_test' could be found (are you missing a using directive or an assembly reference?)
I have tried XXX.InnerHtml and I have tried this.XXX.InnerHtml and get same problem.
How do I successfully refer to ID'ed HTML elements in code behind?

View 2 RepliesI have a create view that I cannot set HTML attributes on. I have tried various ways but still cant set an attribute. Currently I'm trying this

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.

Isnt it possible to shorten this method? What i would like to know if its possible to just do something like

I have a tree view created using HTML and Jquery only.
I would like to know can i create a custom control using just HTML and jquery to make it re-usable.
I wish to use the same form for adding and editing records within a database using a partial view. I understand that this is fine as the standard Html.BeginForm automatically output the correct html depending on the action that is being used (Add / Edit). However, I need to out said form with some extra HTML attributes. There does not appear to be an overload that allows this to happen without also specifying the ACTION and CONTROLLER names. If I hardcode these then surely I cant use the same form for edit and add automatically? Or am I missing something?
View 1 RepliesI'm creating a custom server control which needs to take in a root-relative path for one of it's properties. I use the UrlProperty, but when I select a file in the markup, the selected path doesn't inlcude the the "~/". I'd like to mimic the behavior of a hyperlink. So let's say I have this:
<asp:HyperLink ID="HyperLink1" NavigateUrl
When I type in an equals sign after the NavigateUrl property, intellisense pops open a URL picker and I can pick from any page to produce this code:
<asp:HyperLink ID="HyperLink1" NavigateUrl="~/default.aspx"
this code has the "~/" in front. When I use my control, I have this:
<cc1:TestControl ID="TestControl1" Url="default.aspx"
the C# code has this property:
[UrlProperty]
public string Url { get; set; }
Does anyone know how I can make the "~/" be placed in front to make a root-relative path?
