I would like to read the Form value of a control (e.g TextBox), i.e ‘Request.Form["[Control_Name_Here]"]. The problem with using say TextBox.Text is because if you explicity set it yourself in the Page_Load, there is no way you can get back the ‘original value’ submitted in the form.

As you know, Asp.Net generates a unique ID/Name for the control. The Request.Form is based on the name attribute of a control. Each webcontrol has a ClientID property, however this does not match the name. The name seems to be almost like the ClientID, having $ instead of _. Is there a way to easily get the value from the form, without resorting to having to replace the _ to a $?

And this should also cater for other naming-conventions, because as from Asp.Net you can also choose to have a control’s id statically-generated, rather than dynamically.

    It sounds to me like you’re not looking for the .ClientID property, but the .UniqueID property of the Control.

    See: MSDN

    Edit: Also, is there a reason you’re always setting the .Text property within the page load? Instead of for example check the Page.IsPostBack property instead and only set the .Text if it’s false?
