Asp.net is a beginner who has learned how to simulate the dialog box effect,
There is a textbox and a button on the home page. click the button to bring up a modal display page.
, Enter the text, click OK to return to the home page, and return the text value.
It's very simple.
Home page:
@? Page? Language = "C #"? %>
Script? Runat = "server">
???? Private? Void? Page_load (object? Sender ,? System. eventargs? E)
???? {
???????? If? (! Ispostback)
????????? Btnopen. Attributes. Add ("onclick ",? @ "Var? Strreturn ;? Strreturn = Window. showmodaldialog ('dialogform. aspx ', null, 'status: No; dialogwidth: 250px; dialogheight: 125px; dialoghide: true; help: No; scroll: no'); If? (Strreturn ?! =? Null )? Document. getelementbyid ('txtvalue'). value = strreturn ;");
????}
