How can you enable automatic paging in DataGrid?

 Answer:

To use the built-in paging of DataGrid, set the AllowPaging property to true and the PageSize property to the number of items to be displayed per page.

We can also specify the style of the paging controls. Paging controls are LinkButton controls which we can choose either in "Next and Previous" format or Page Numbers format, and these allow users to jump to a specific page. You can specify how many numbers are displayed; if there are more pages, an ellipsis ( … ) is displayed next to the numbers.

We must also create an event-handling method that responds when users click on a paging control.

In order to enable paging in Datagrid you need to (very short version):

* Set the "AllowPaging" property to true.
* In PageIndexChanged event handler set the current PageIndex clicked.
Below is an example in C#:

//Declaring DataGrid
protected System.Web.UI.WebControls.DataGrid DataGrid1;
//Binding DataGrid with a Data Source (DataSet in our Case)
DataGrid1.DataSource = dataSet1;
DataGrid1.DataBind();
this.DataGrid1.PageIndexChanged += new System.Web.UI.WebControls.DataGridPageChangedEventHandler(this.GridPageIndexChanged);
//Implement the EventHandler
private void GridPageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
{
DataGrid1.CurrentPageIndex = e.NewPageIndex;
//Bind the DataGrid again with the Data Source
DataGrid1.DataSource = dataSet1;
DataGrid1.DataBind();
}
