Automatic Input Using Web Services

Automatic Input Using Web Services

The Web Service is used to automatically complete input. Front-End Interface:

 

Code

<Asp: textbox id = "textbox1" runat = "server"> </ASP: textbox>

<Ajaxtoolkit: autocompleteextender id = "autocompleteextender3" runat = "server" enabled = "true"
Targetcontrolid = "textbox1"
Servicepath = "/lscomplete. asmx"
Servicemethod = "getcompletedepart"
Completioninterval = "500"
Completionsetcount = "10"
Minimumprefixlength = "1">
</Ajaxtoolkit: autocompleteextender>

 

Background code:

Create a Web Service:
