I need to know on the serverside, if a RadioButton has been disabled (by javascript) on the clientside.
The (serverside) Enabled property is not the same as the (clientside) disabled property. Using MyRadioButton.Attributes("disabled") doesn't do the trick either.
Anyway, if for example I have a textbox that I want to enable when the user check the desired checkbox/radiobutton, I like the textbox to be default enabled=false. What's the good approach between these two?
a.) client side

I'm making a website in ASP.NET 4.0 where I make use of the RequiredFieldValidator control to validate a wizardstep.It works perfectly with Javascript enabled, but when I turn it off (in my Firefox) it just goes to the next step.We don't do a Page.IsValid check, but we don't do much on the "next button clicked" event either.Certainly not something that is forcing it to go to the next step.
View 15 RepliesI am using ASP.NET 3.5.
When the user click on say btnSubmit I want to first execute some JavaScript code and then execute some C#/VB.NET code.
Is this possible? If so how would one do it?
Let's say I have a function that takes a string. That string contains the fully name of an enum type (e.g. "MyCompany.Area.AotherNamespace.MyEnum").
How could I create an array of strings (or List<string>) whose elements are the values of MyCompany.Area.AotherNamespace.MyEnum?
Is that even possible?I'm basically trying to serialize an enum type serverside and then output it in clientside JavaScript so I don't have to define an enum in two places--in my C# and my JavaScript.
I'm curious, anyone know the mechanism a checkbox control uses to remember that its checked or not checked after a postback?If I add them manually to a page via html as in <input type="checkbox"/> I have to use javascript and hiddenfields to keep things checked after a postback and I would have to have an onclick="dosomething()" inside the tags.Viewing the html source code for a page with a .NET checkbox control, there is nothing like that there.
I was writing a custom control and rendered my own checkboxes when I came across this problem. After the postback, the control would reload the checkboxes from viewstate and forget the user had clicked anything. As I couldn't use hiddenfields to track the changes (they got reset from viewstate too), I ended up using .NET checkboxes as childcontrols instead but this experience got me thinking.
I need to print a text from a panel of a page. When user click on print button, user should selecl available printer which is connnect to the system.
after selecting, available printer it should automatically go for print.
These activity should do in serverside only
i have a complete form in my database as row for example name of the field ,is mandatory, sortid, regularexpression, datatype, maxlength , default value etc. So the form is completely dynamic.now i want to perform the client side validation on the form . What will be the best practice for doing that? like i have to see that if the field is mandatory check it for null and if not then leave it on the client side . i am thinking about setting hidden field for it .
View 2 Repliessubject says it all...... when using the various validation controls like requiredFieldValidator, and EnableClientScript is true (the default), does that mean that the only validation is done client side? or does it mean that it is done client side in addition to server side?
I know if the only validation is done client side, like with javascript, it can easily be circumvented. I want to make sure my validation is done serverside, so do I need to set EnableClientScript to false?
I have a required validator that I check a textbox clientside, but then on post I check the database for values that have been used. I want to show the error in the RequiredFieldValidator when it post back. How do I do this?
View 1 RepliesI have to create a HtmlInputText control in code and while in code set it so that it will respond to text changes purely on the client side and not generate a server side event. In an aspx page this would be done like so:
<input id="txtBox" runat="server" onchange="clientsidefunction();">
But in creating this control I cannot determine anyway of setting the onchange client side event. I can setup a server side event by entering:
AddHandler txtBox.ServerChange, AddressOf.serversidefunction Is there anyway to set the clientside onchange event?
Why am I getting this error? I'm trying to do a calculation on my GridView2 and I'm using clientside javascript. I need to add the onkeyup attribute. How do I do this?

CType(GridView2.FindControl("TextBox13"), TextBox).Attributes.Add("onkeyup", "calculateSubTotal")
End Sub

I have a link button inside a repeater. How would I directly call the serverside (ItemCommand) method during postback. I want to skip the page_load. The wierd thing happening is, if I put (!Postback) it doesn't execute other methods on postback but it does if I don't set the !postback condition. I have repeater inside a updatepanel in UserControl.
View 1 Repliesi have a gridview with commandbutton column and a textbox template column. My requirement is changing the text and hitting the enter key should also perform the same function as the command button. So i enabled the autopostback of the textbox.But if i click the command button after changing the text in the text box fires both the TextChanged event as well as the item command event. Is there anyway to bypass the Textbox text change event if i postback using the grid command button?

I have a problem with the ASP FileUpload control. It occurs in Safari and on websites where anonymous authentication is disabled and windows authentication is enabled.
When I select a file in the upload-control and then press an ASP-button the serverside event for the button is not triggered and PostBack is false.
Steps to reproduce the error:
1. Create a page with a file upload and a button. Print a message in the page's load event so you can see that if postback is true or false
2. Open IIS-manager and Add a new application that points to the folder where the page is
3. Disable Anonymous Authentication, ASP.NET Impersonation and Forms Authentication for the application
7. Enable Windows Authentication for the application
8. Browse to the page with Safari
9. Select a file with the upload control
10. Press Ok. Postback is false
If you then enable anonymous authentication on the web application and restart the browser postback works as expected.
I am trying to create an HTML button that can use a C# server side delete function. since I don't know how many results I will have at the page, the control is created dynamically when the end user searches for current Messages:

I know the built-in ASP.Net validators come with a client-side framework, however I've been unable to find anything that lets me check a single validator for it's Valid state.
The validator in question is a RegularExpressionValidator, which I use to determine whether an e-mail address is valid or not.
Here's some brief code:

Can any one provide me an idea about any ajax control which has following capabilities:
User should able to type to get auto-suggestions Dropdown should only display the values starting with the keyed-in characters. Most importantly there should be only one postback to fetch all the data to client side on the first key-in and then should filter the list values based on rest of the keys.
