Question

I have a repeater, which contains a text box (html) in the ItemTemplate.

I cannot create an asp textbox, as the text box in question needs to be accessed through jQuery for user manipulation of the text box.

Once the user is done, an asp button is pressed in the respective repeater row, and I would like to get the value which the user has entered into the text box, through the code behind (c#).

Could anyone tell me if this is at all possible? If so, could some code be suggested?

Otherwise, any non-AJAX alternatives?

There is no issue with referencing asp.net components in jQuery. A couple of things to know about this:

1. The item will an have id that includes the ID value that you originally gave the control. Using the current encoding scheme (which I cannot imaging Microsoft changing significantly), <asp:TextBox ID="txtBox" runat="server" /> becomes <input id="...._txtBox" name="...$txtBox" /> in the HTML. A jQuery selector like: $(input[id$=txtBox]) will find it.
2. Because the asp controls eventually resolve to good-old HTML form elements, you treat them exactly like an HTML element you created directly. In this case, you enable/disable it using the pseudo-class disabled.
3. I learned much of this by viewing the generated source for my web pages and seeing what was happening. I like FireFox with the Web Developer’s Toolbar and its View Generated Source command.
