C# - How To Make XHTML Validation Happy When Using Custom System.Web.UI.Control

Aug 28, 2010

I am sure this question has been asked and answered; but I haven't managed to find it...

I am creating a very simple custom System.Web.UI.Control that has a few properties. I can define in my ASPX page the following tag and everything is happy:

<ns:MyControl runat="server" MyProperty="Value" />

However, if I want to have one or more "child" properties, like so:

<ns:MyControl runat="server" MyProperty="Value">
<Element AnotherProperty="AnotherValue1" />
<Element AnotherProperty="AnotherValue2" />

what I need to do to make the XHTML validate. I always have

Content is not allowed between the opening and closing tag of element 'XXX'

Element 'XXX' is not supported

The name contains uppercase characters, which is not allowed

The code actually runs as expected, but I haven't manged to find a good example on how to do this correctly so that everything validates. In terms of implementation of the Custom Control, I just have all properties stubbed out at the moment, and looks something like:

public class MyControl : Control[code]....

Ultimately, Element is intended to build up a collection of Elements. Any insight on how to do this properly and have the XHTML validate

Add A Custom / Namespaced XHTML Attribute To A Web Control Declaratively?

Aug 24, 2010

Normally, unknown attributes of a webcontrol are passed through to to the rendered element in the browser. So the following works.

<asp:label runat="server" Text="Label Text" helpId="101" />

However, if you use a namespaced attribute like the following

<asp:label runat="server" Text="Label Text" myNs:helpId="101" /></div>

The attribute is not rendered to the client, even when the custom namespace is declared in the html element like: <html xmlns= [URL] Does anyone know of a way to get this to render to the client, without having to use a custom control. A module or other globally "pluggable" solution would be acceptable.

How To Make A Website In XHTML And CSS / Finding Step By Step Tutorials

Jan 22, 2010

Well as the title says I am a total noob to web programming. I have experience in XHTML and CSS and that is it, and it is time to expand my knowledge and start making much better websites

I have a project to completely rewrite the site [URL] and want to do it in ASP.NET rather then PHP, and since I do not know either language I would rather learn this one instead.

My question is simple, where do I start? I learn well by reading books and doing examples and building example websites, that sort of stuff. Can anyone suggest any good book titles that will get me started in the right direction? A friend sent me the PDF version of the book: "Learning ASP.NET 3.5, 2nd Edition (Build web applications with ASP.NET 3.5, AJAX, Linq and MORE)." This is so far the only resource I have. The only thing about that book is that it promotes using the WYSIWYG style of web design and I
have always been tought to stay away from that.

C# - Add Child Nodes To Custom User Control Derived From System.Web.UI.Control?

Sep 4, 2010

I would like to know how to add some additional child nodes to a custom user control class derived from System.Web.UI.Control. For example currently I have a control that contains no child nodes and on the design surface looks like the following.

<cust:MyCustomControl id="ctlMyCustomControl" runat="server" attribute1="somevalue" attribute2="somevalue" ></MyCustomControl>

What I am looking for is to have the ability to add n number of child nodes to this control from the design surface and then access their values from the code. So adding to the control stated above.

<cust:MyCustomControl id="ctlMyCustomControl" runat="server" attribute1="somevalue" attribute2="somevalue" >

It is not clear to me how to access the child nodes.

C# - Custom Control Doesn't Fire Validation

Jun 4, 2010

I've written a custom ASP.net control that descends from LinkButton and overrides the Render() method. I'm using it to replace ImageButtons in the site I'm working on so we don't have to have an image for each button. This control works fine, does the required post-backs etc., however it doesn't fire the validators in its validation group. This is obviously an issue. The code for the control is (condensed) as follows:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public class CustomButton : LinkButton
public string SpanCssClass { get; set; }
protected override void Render(HtmlTextWriter writer)
if (!Visible)
writer.AddAttribute(HtmlTextWriterAttribute.Name, UniqueID);
writer.AddAttribute(HtmlTextWriterAttribute.Id, ClientID);
writer.AddAttribute(HtmlTextWriterAttribute.Class, CssClass);
string postback = string.IsNullOrEmpty(OnClientClick) ? "javascript:__doPostBack('" + UniqueID + "','');" : OnClientClick;
writer.AddAttribute(HtmlTextWriterAttribute.Href, postback);
writer.AddAttribute(HtmlTextWriterAttribute.Class, SpanCssClass);

Does anyone know why this would not be causing the validators to fire? I was under the impression that leaving all the other methods in LinkButton un-overridden would leave all the other functionality the same.

Finding Best Treeview Control That Renders Valid Xhtml And Works Without JavaScript

Oct 29, 2010

I'm looking for an ASP.NET control that renders a tree structure, very much like the ASP.NET TreeView control, but filling the following requirements:

Dont uses tables for rendering tree structure.
Markup Adhering to valid XHTML 1.0 Strict.
Works with AND without javascript.

Also, if the control is licensed under a MIT och GPL licens that would be great, but commercial controls is also of interest.

Do anyone know of any such control? If not, well, then I'll simply have to write the control myself. More fun in my own opinion, but likely more time consuming.

Web Forms :: Custom Validation Only Works For FileUpload Control

Oct 12, 2010

I have 2 custom validator controls on my page but for some strange reason the Custom Validator for FileUpload control works and the custom validator for TextBox control does not work. Here is the aspx code:

<asp:FileUpload ID="_fileCv" runat="server" Width="500px" /><br />
<asp:RequiredFieldValidator ID="_rfvFileCv" runat="server" ErrorMessage="Resume; " ControlToValidate="_fileCv" SetFocusOnError="True" ValidationGroup="APPLY">
<img src="images/mandatory.gif" alt="Required" /></asp:RequiredFieldValidator
<asp:CustomValidator ID="CustomValidator1" runat="server" ControlToValidate="_fileCv"
ErrorMessage="Max file size for documents is 4MB." OnServerValidate="CustomValidator1_ServerValidate" ValidationGroup="APPLY"></asp:CustomValidator>
<asp:TextBox ID="_txtHealthComments" runat="server" TextMode="MultiLine" Rows="5" Width="500" />
<asp:CustomValidator ID="CustomValidator2" runat="server" ControlToValidate="_txtHealthComments"
ErrorMessage="Kindly enter health Comments ." OnServerValidate="CustomValidator2_ValidateHealth" ValidationGroup="APPLY"></asp:CustomValidator>

Here is the code behind:
protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args) {
if (_fileCv.FileBytes.Length > 4194304) {
args.IsValid = false;
} else { args.IsValid = true; } }

C# - Add A Validation Support To DropDownList By Creating A Custom Control?

Feb 2, 2011

I'm trying to add a validation support to DropDownList by creating a custom control inheriting from DropDownList:

public class MyDropDown: DropDownList, INamingContainer
private const string ValidatorID = "Validator";
private RequiredFieldValidator _validator;


My class implements INamingContainer because I wanted to avoid naming conflicts. Unfortunately when I try using this control I get the following exception:

Unable to find control id 'MDD' referenced by the 'ControlToValidate' property of 'MDD_Validator'

This is happening beause for INamingContainer FindControl(NamingContainerId) returns null.

When I remove INamingContainer implementation and set validator ID in the following way:

_validator.ID = String.Format("{0}_{1}", ID, ValidatorID);

Everything is working fine, and id given to Validator is the same as it would be inside Naming container.

But is there a way to accomplish this WITH INamingContainer ?

Custom TextBox Control With Built-in Client-side Validation?

Jan 30, 2011

I have a textbox in my application which has multiple validation on it e.g. RequiredFieldValidator, RegexValidation and CustomValidation. My page has several similar textboxes. So I just copy-paste and change id and controltovalidate properties and it is working.

Since similar tbxs are going to be used on another page as well, I think it would be nice to create my own custom TextBox control with built-in validation.

Here are two approaches I have found and tried:

1: Implement from IValidator perform my custom validation in Validate Method. As shown here: Self-Validating TextBox But it does not show how to implement client-side validation.

2: Create custom control that derives from TextBox and add asp.net built-in validators I need. As shown here:Custom TextBox. I tried the code and it works server/client side.

I like the first approach but don't know how to implement client-side validation. I know I need a client-side js function. I can do that. I know how to include my js file using Page.ClientScript class but don't know how to integrate all together and make it work.

I can create a UserControl or the second approach above but for now I am specifically looking to learn and implement client-side validation from custom control.

Forms Data Controls :: Make A Databound Control With A Custom Scrollbar?

Mar 22, 2010

I'm working on a website to showcase some of my bird photography, using ASP.NET 2.0 and C# with a SQLServerExpress backend.What I have right now is a ListBox bound to my database that displays a list of common names of birds and when the user clicks on an item in the listbox the main image on the page is changed to the image for that bird. For style reasons I want the listbox to always be a fixed size and because I specify the size (using CSS) a vertical scrollbar appears. My problem is that I want to provide my own images of arrows that go above and below the box such that when the user hovers over an arrow the box scrolls slowly and when the user clicks an arow the box scrolls quickly. Finally, my main problem is that I want to get rid of the ugly default vertical scrollbar that comes with ListBox.

Can you guys help me figure out how to do this? I don't mind using a different control other than ListBox as long as it is available in ASP.NET 2.0 and as long as it can be bound to my db. I also don't mind using JavaScript (which I'm sure I'll end up doing for the hover effects). Right now I'm fooling around with subclassing the ListBox control but I've never subclassed a control before so I'm somewhat clueless.

Web Forms :: Validating Input In A Custom User Control Using Jquery Validation Plugin?

Jun 18, 2010

I have a custom user control with some input fields and a submit button. I need to validate the fields using the jquery validation plugin when the submit button is clicked. (The function of the submit button is to create another custom control which displays the data entered in the above mentioned control)

Bt as far as I knw, validation plugin works only with form validation ryt? And my custom control does not contain a form tag as I am using master pages. The custom control is present in one of the content pages and the master page already contains a form tag with a runat=server attribute. And I guess one page can contain only a single form tag with runat=server attrib ryt?

So how do I get it to work?
