To bind a gridview you need to have 2 things<br />
<br />
(A) Datasource : the one which holds records, could be dataset, dropdownlist, arrays etc. Assigned to controls (e.g. Grid view) like Gridview1.Datasource= your datasource<br />
(B) DataBind : Binding database to controls which is Gridview1.DataBind<br />
<br />
Now you wish to change the datasource on postback. So if that changes on first time page load you would get your (old) datasource and after then page loads you would get your (new) datasource. Is that what you wished? If no, then please explain or post your code or any link which justified your example. I'm asking such long questions, as this is quite rare of changing datasource and that too on postbacks<br />
<br />
thanks<br />

Change datasource of gridview on postback

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.

Microsoft Development

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications
