How can we do Paging in gridview? [closed]

I need to do paging in grid view that actually binds from a list. Can any one please help me out? Actually as the data is extracted from a list , am getting "null" while data it is being populated to the next page. So i would like to know whether the users here faced such a criteria.

Method used to bind the grid is as below,

private void bindGrid()
 {
if (items != null)
{
foreach (var item in items)
{
name.Add(new organisationName(((System.Xml.XmlElement)((System.Xml.XmlNode[])(item))[7]).InnerText,
((System.Xml.XmlElement)((System.Xml.XmlNode[])(item))[3]).InnerText));
}
searchResultGrid.DataSource = name;
searchResultGrid.DataBind();

}

}

and in the PageIndexChanging event of gridview i used the below code

protected void searchResultGrid_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
bindGrid();
searchResultGrid.PageIndex = e.NewPageIndex;
searchResultGrid.DataBind();

}

aspx page

<asp:GridView ID="searchResultGrid" runat="server" PageSize="20" Width="60%" AllowPaging="true"
Visible="False" OnPageIndexChanging="searchResultGrid_PageIndexChanging" OnRowDataBound="searchResultGrid_RowDataBound"
OnSelectedIndexChanged="searchResultGrid_SelectedIndexChanged" OnRowCommand="searchResultGrid_RowCommand">
<Columns>

</Columns>
<EmptyDataTemplate>
No Data Found</EmptyDataTemplate>
</asp:GridView>

Thanks in advance

Paging is a inbuilt feature of GridView control and the solution to bring them are really strait forward.

Go through this article to get better idea on paging. http://msdn.microsoft.com/en-us/library/5aw1xfh3.aspx.

You can use one of two ways to page your Gridview.

1-use the built in paging in asp.net gridview control through (AllowPaging).

2-make your own paging way.
