I want to have the entered text once again in textbox after postback.

thank you

For dynamically created controls, you need to create them and add them to the control tree in the Page_Init() event; Page_Load() is too late, and Page_PreRender() is way too late.

Once in the control tree, the runtime will restore the state of the control for you after a postback. You can access the contents of the control using myTextBox.Text -- you don't need to use Request.QueryString

For a control that only contains a TextBox, things would be much easier if you used a user control rather than an INamingContainer. That way, you could just use <asp:TextBox> in your .ascx markup.

A custom control? Any posted control like this loads its data in LoadPostData method. You can override this in your custom control class, and access the value from teh control via:

var text = postDataCollection[textboxID];

The textbox within your custom control has to have an ID.

If you are talking something else, let me know the specifics.

Thanks.

1. (TextBox)Control.FindControl("control id")
2. get dynamic control's value in postback , Request.Form("control client id")
