So you are doing this directly from a Windows Forms or WPF application? Okay, there are a couple of things you need to know.

The first thing to be aware of is the fact that ASP.NET mangles names so the control you are looking for will have a different name. It does this so that you can have the same client id in two controls, their ids won't clash in the rendered page.

The second thing is that you need to wait until the page has loaded before you try to read from the field. The web browser control does have events that you can hook into to get this.

Solution 1

write following syntax to get value from TextBox within Detailview...Here I assume that Name of Detail View is MyDetailView & Name of Text Box is MyTextBox

var name=$get('<%= MyDetailsView.FindControl("MyTextBox").ClientID %>').value
