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" />
</ns:MyControl>
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:
[ParseChildren(true)]
[PersistChildren(false)]
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
How can i make a control required to put input depending on the radiobuttonlist selection? Let me try to clarify a bit more. I got 2 radiobuttons, if one gets selected, nothing else has to be done. But if the otherone gets selected, a textfield must have some input too.
View 2 RepliesI 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.
I use VB. When put text into textbox1. and then push "enter". It will trigger one event. How can I do it? What to write in the file *.aspx.vb?

View 3 RepliesI have TextBox1 (enabled = true) and TextBox2 (enabled = false) in my WebForm on loading. Both are validated by means of a RegularExpressionValidator.
How can I set TextBox2 enabled = true ONLY AFTER (!) the text inserted in TextBox1 has been validated and accepted as valid ?
Can this be done on client side exclusively or is some code behind absolutely necessary ?
how to validate
1.TextBox should not accept the DateFormat
2.Should not accept only numbers
3.it's accept combination of numbers and alaphabets.

I have a project due for my Visual Basic course. The project is creating a web application. I'm setting up the application where the user will enter information in a textbox. I want to be able to test the value entered in the textbox. There are three test conditions - less than a certain number, between a range of numbers, and greater than a certain number. I'm familiar with Visual Basic but not that with Visual Web Developer. I want to display a message to the user that tells them the value entered is low, normal, or high, and display additional information. The question I have is can I attach three validation controls to a single textbox? I know how to attach one validator control, and that works fine. I try to attach three controls but when I run the program all three error messages display, which is not what I want. I think I would need to code a custom validator but not sure how to do that.
