The HTML code of the GrdiView is:
-----------------------------------------------------------------------------------
<asp:GridView ID="GridView_NewStaff" runat="server" AutoGenerateColumns="False"
CellPadding="4" Font-Size="Small" ForeColor="#333333" AllowPaging="True"
AllowSorting="True" onpageindexchanging="GridView_NewStaff_PageIndexChanging"
PageSize="20">
<pagersettings firstpagetext="First" lastpagetext="Last">
Mode="NextPreviousFirstLast" NextPageText="Next" PageButtonCount="4"
PreviousPageText="Previous" />
<columns>......
-----------------------------------------------------------------------------------
The C# code is:
-----------------------------------------------------------------------------------
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bindGridView();
}
}
protected void Button_ReadFile_Click(object sender, EventArgs e)
{
bindGridView();
}
public void bindGridView()
{
if (FileUpload_StaffInfo.HasFile)
{
string InfoFile_Name = Server.MapPath(InfoFileDirectory) + FileUpload_StaffInfo.FileName;
FileUpload_StaffInfo.SaveAs(InfoFile_Name);
dataTable_Excel = new DataTable();
if (InfoFile_Name.EndsWith(".xlsx"))
{
StaffExcelXML StaffNewXML = new StaffExcelXML();
StaffNewXML.ExcelInput(InfoFile_Name, ref dataTable_Excel)
}
else if (InfoFile_Name.EndsWith(".xls"))
{
StaffXLS StaffNewXLS = new StaffXLS();
StaffNewXLS.ExcelInput(InfoFile_Name, ref dataTable_Excel);
}
GridView_NewStaff.DataSource = dataTable_Excel;
GridView_NewStaff.DataBind();
}
}
-----------------------------------------------------------------------------------
Everytime after clicking the Next, or the Previous, or the First, or the Last, it always shows the first page's data. Could anyone help me with this?
