gridview paging without using sqldatasource control(asp.net with vb code)

For paging a Gridview manually we have to handle the Gridview’s PageIndexChanged Event. In the event we need to change the PageIndex of Gridview to the page that user has clicked and again bind the Gridview.
firstly select gridview property and select pageing=true.

and code behind
protected void gvPaging_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvPaging.PageIndex = e.NewPageIndex;
gvPaging.DataBind();
}

This is all you need to do to make manual paging in the Gridview.

For manually sorting in Gridview we need to handle the Sorting event of Gridview. Here is the code to do it.

protected void gvSorting_Sorting(object sender, GridViewSortEventArgs e)
{
DataTable dtSortTable = gvSorting.DataSource as DataTable;
if (dtSortTable != null)
{
DataView dvSortedView = new DataView(dtSortTable);
dvSortedView.Sort = e.SortExpression + " " + getSortDirectionString(e.SortDirection);
gvSorting.DataSource = dvSortedView;
gvSorting.DataBind();
}
}
private string getSortDirectionString(SortDirection sortDireciton)
{
string newSortDirection = String.Empty;
if(sortDirection== SortDirection.Ascending)
{
newSortDirection = "ASC";
}
else
{
newSortDirection = "DESC";
}
return newSortDirection
}
