GridView and Invalid CurrentPageIndex Value Exception - .Net 3.5 Version
In my previous GridView entry titled as GridView and Invalid CurrentPageIndex Value Exception I made an example about how to corrigate paged GridView page index before grid is bound to data. Let's to id now .Net Framework 3.5 way.
public static class GridViewExtensions
{
public static void CorrigatePageIndex(this GridView gdv, Int32 rowCount)
{
Int32 newIndex = gdv.PageIndex;
if(gdv.PageSize> 0)
if((Int32)Math.Ceiling((decimal)rowCount / gdv.PageSize) < newIndex)
newIndex = (Int32)Math.Ceiling((decimal)rowCount / gdv.PageSize);
if(newIndex <0)
newIndex = 0;
gdv.PageIndex = newIndex;
}
}
Now we can corrigate page index usng the following code.
protected void Page_Load(object sender, EventArgs e)
{
if (this.IsPostBack)
return;
DataTable dt = GetRows();
gdvList.PageIndex = 15;
gdvList.DataSource = dt;
gdvList.CorrectCurrentPage(dt.Rows.Count);
gdvList.DataBind();
}
