Adding Custom Attributes To .NET RadioButton Control
Sep 23, 2010
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;

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 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 ?

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:

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 am extending the TextBox class to include CustomValidator along with the TextBox. I have created properties like CSSClass for ErrorMessage, CustomErrormessage for ErrorMessage on failure. But I am not sure how to get server side validation method in the form of tag. Example:
<asp:CustomValidator runat="server" id="custPrimeCheck"
ControlToValidate="txtPrimeNumber"
OnServerValidate="PrimeNumberCheck"
ErrorMessage="Invalid Prime Number" />
PrimeNumberCheck is the method name which is passed as parameter, same way I want to pass method in my custom TextBox for CustomValidator to run on server side.

I want to add an attribute to the dataset declared below whose value is the value of one of the field in the row. So I want to add the id as shown below.
<root>
<Table id="GAS-405">
<apple>2009FA</apple>
<orange>3.00</orange>
<pear>BGPR</pear>
<banana>GAS-405</banana>
</Table>
</root>
This will me identify the node later in my application. Is this possible? Is this easier to do using XMLDocument?
Dim sdaFoo As SqlDataAdapter = New SqlDataAdapter("SELECT BLAH FROM BLAHBLAH", conn)
Dim dsFoo As DataSet = New DataSet()
dsFoo.DataSetName = "apple"
sdaFoo.Fill(dsFoo)
dsFoo.WriteXml("C:Inetpubwwwrootfoo.xml")

I have a usercontrol (ascx) that I want to dynamically add to a page.
Neither the control nor the page has a namespace (thanks crappy vendor).
When I use the following, it tells me it cant find the "type or namespace"
StayTunedControl = (UserControler_StayTuned)LoadControl("~/UserControler/StayTuned.ascx");
Page.Controls.Add(StayTunedControl);
StayTunedControl.StayTunedID = Convert.ToInt32(IncludesStayTunedMeta.Value);
After some tweaking to the namespaces, etc, I am now at a point where the 3rd line above generates the following error:
'System.Web.UI.UserControl' does not contain a definition for 'StayTunedID'
I was hoping that casting StayTunedControl as type (UserControler_StayTuned) would fix this.

I have a dropdown list where I need more than just a bound value and a display value. I am using this in the page load event to add a custom attribute:
[Code]....
I'm actually looping through a sqldatareader for a list of employees, but for simplicity just consider the single option added above. When I go to check the attribute EmpNum for the selected option, I am getting "null":
[Code]....
Now the really weird part...If I add an option in the HTML source identical to the one that gets added in the codebehind, the javascript function works for that row, but not the row added from codebehind. Here is the rendered HTML for the SELECT:
[Code]....
If I select the 1st record (added from HTML source at design time) the alert says "12345". If I select the 2nd record, the alert says "null". I CAN get the value ("999-99-9999") and the displayed text ("John Doe") for either record, just not the EmpNum attribute, even though the HTML is exactly the same. I am completely stumped on this one.

I just want to add and attribute called "pubID" to an image button with the value I give it and then call that value on the image button click event. This image button was created dynamically as well. At the moment this code is not working. When debugging it looks like Pubid is getting assigned a value but on the click event, the attribute isn't being retrieved correctly.

The built in Asp.Net Controls (label, Textbox, etc.) all have a CssClass property that can be set, what do I need to do to implement that for a Web User Control?
I know how to add a property and pass thru the get & set to the corresponding Asp.Net control (example if I have a label I know how to create a LabelCssClass property that provides a get & set, but the control itself how do I set a CssClass or ClassName property.

I have a problem with a GridView that I can't figure out. It's inside an UpdatePanel and has been working fine for a long time. Today I have added a few lines to the code behind to add javascript to each row so that the user can just click the row to view the record. This works fine too, except that it breaks the paging of the GridView and I don't understand why.
Here is my code (The controls lstStatus and txtSearch are elsewhere on the page):
[Code]....
And in the codebehind the lines which break paging are the following three, in the RowDataBound event:
[Code]....
I've tried messing with the viewstate of the UpdatePanel, changing its UpdateMode to 'Always' and it's ChildrenAsTriggers property to 'True' but none of this makes any difference, and besides, it's been working for months as it is until I introduced these three new lines into the code behind.
Can anybody see why add these attributes to the row breaks paging?

Is it possible to add attributes in a linq query along with the other object data?
Here's what I have

I am currently using the ActiveDirectoryMembershipProvider just for authentication on an internal business app built in asp.net. This works like a charm.
I am now looking to add some functionality to handle custom profile information for a user, ideally also stored in Active Directory.
For a simple example let's just say the custom attribute is FavoriteColor. Then the goal would be for my app to be able to read in this custom attribute for the authenticated user.
I have looked into ADAM a bit. That looks like it would be great for a Role Provider, but I haven't really found anything that indicates it would work well for a Profile Provider or if it would even let me store custom attributes like FavoriteColor. Maybe someone knows better?
I'm also pretty new to Active Directory so maybe there is even an option to store custom user attributes (like FavoriteColor) within it? In general I am just looking for ideas about the best way to implement this?

The control's client-side markup should look like:

As you can see, attributes for the first <li> element is not rendered.
Here's the Render method:

items collection is filled correctly. Debugging the code showed that AddAttribute is called for first Li element, but the output is rendered incorrectly.

I am working on a project where we want to keep a history of a particular object. On save I want a method on the object that will determine if it has changed so that I can call a method to save its current state to history. E.g. I populate a form from an object the user makes changes (or possibly not) and submits the from. I want to take my original object and a copy of that object that has been updated from the form and determine if it has changed at all. Additionally I may decide at some point that certain properties don't matter (e.g. if Name changes I won't track it).
I'm thinking the easiest/most flexible way to accomplish this would be if I could give the properties I care about a custom attribute [ChangeTracked] and then I could use reflection to get a list of all properties with that attribute and loop through them comparing A.property == B.property to determine if any have changed.
Would this work? Is there a significantly better/easier way to handle this, like some sort of built in method you can add to an object to determine if the values of any properties have changed? Whatever the solution some psudo code would be appreciated. Just as a point of clarification the solution needs to determine if the value I care about has actually changed not just if it has been assigned since it was created i.e. if I set Name="bob" and it was already "bob" before my assignment this does not count as a change.

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 developed a User Control in inline code model and convert this into dll and try to add it into Visual Studio ToolBox. It shows error "There is no component found in the object.". It is showing actually because i have not added ToolBoxData attribute just before the class declaration, because there is no class declaration in the inline code model. I don't know where i have to add ToolBoxData attribute.

I am creating a control that inherits from the RadioButton, so that I can set the GroupName property manually. Everything is working okay apart from the fact that when the page posts back, the RadioButton becomes unchecked if it has previously been checked. This is the first time I've tried inheriting from controls, so must be doing something really silly. I would welcome anyone helping me to improve my code so that the control's Checked value persists through postbacks. I am causing a postback using a button, not the actual RadioButton itself, if that makes any difference. Here is my code:
