how pagging in datalist

Hey Rawat !


try like this :




Next, Previous, First and Last button part:

protected void lnkNext_Click(object sender, EventArgs e)
{
index += 1;
Bind();
}
protected void lnkPrev_Click(object sender, EventArgs e)
{
index -= 1;
Bind();
}

protected void lnkFirst_Click(object sender, EventArgs e)
{
index = 0;
Bind();
}
protected void lnkLast_Click(object sender, EventArgs e)
{
index = Convert.ToInt32(ViewState["LastPage"]);
Bind();
}




PagedDataSource CS Part:


public int index {
get {
if (ViewState["index"] == null)
return 0;
else
return Convert.ToInt32(ViewState["index"].ToString());
}
set{
ViewState["index"] = value;
}
}

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
Bind();
}

private void Bind()
{
DataTable dt = FillData();

if (dt.Rows.Count > 0)
{
PagedDataSource _pageDataSource = new PagedDataSource();
_pageDataSource.DataSource = dt.DefaultView;
_pageDataSource.AllowPaging = true;
_pageDataSource.PageSize = 5;
_pageDataSource.CurrentPageIndex = index;
ViewState["LastPage"] = _pageDataSource .PageCount - 1;

dlistSimilarAds.DataSource = _pageDataSource;
dlistSimilarAds.DataBind();

lnkPrev.Visible = !_pageDataSource.IsFirstPage;
lnkNext.Visible = !_pageDataSource.IsLastPage;

lnkFirst.Visible = !_ pageDataSource.IsFirstPage;
lnkLast.Visible = !_ pageDataSource.IsLastPage;
}
}
public DataTable FillData()
{
DataSet ds = new DataSet();
//Fetch data and fill your datatable
return ds.Tables[0];
}


May be this work !
