Paging and Sorting a GridView without Refreshing a Page
We
generally use a GridView Control to Display Data and also Perform
Paging, Sorting, Editing, Deleting records. In each of these we have
postback on the page.
To avoid Postback during sorting and Paging, the following code can be used inside the GridView Control.
|
If
you have created a GridView and Bind the GridView using data source
control, you can avoid postback during sorting and paging by setting EnableSortingAndPagingCallbacks' property of the GridView to True.
N:B:
when you use the 'EnableSortingAndPagingCallbacks' property to true for
avoid Postback, you cannot use Template Fields in the GridView.
Ex:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" AllowSorting = "true"
DataSourceID="SqlDataSource1" EnableSortingAndPagingCallbacks = "true">
<Columns>
<asp:BoundField DataField="FIRST_NAME" HeaderText="First Name"
SortExpression="FIRST_NAME" />
<asp:BoundField DataField="LAST_NAME" HeaderText="Last Name"
SortExpression="LAST_NAME" />
<asp:BoundField DataField="ADDRESS" HeaderText="Address"
SortExpression="ADDRESS" />
</Columns>
</asp:GridView>

The grid can be sorted by one or multiple columns. It is possible to use up to five columns per header simultaneously and to use multiple headers you can visit in dapfor. com
