从JavaScript控制中获取价值

Question

Just wondering if you guys can help me with something.

I have created an input control via java script and am trying to get the value from that control using Page.FindControl in asp but it is not finding the control on the page.

Is it possible to find it this way and I am doing something wrong with ID's for example or should it be done by setting a key in the ViewState, or some other method?

If possible can you give a explanation as to why I cannot find the new control via asp.net Page.FindControl if it isnt as simple as incorrect ID's which im sure it isnt.

Thanks for any help.

Two possible resolutions for this:

Use an asp:TextBox instead, in which case you won't even need to use FindControl (in most cases)

<!-- .aspx page -->
<asp:TextBox id="TestControl" runat="server" />

and then

// codebehind
string something = TestControl.Text;

or

Use the text input, and find it on the Form (so old fashioned, but works)

<input id="TestControl" />

and

string something = Page.Request.Form["TestControl"];
