I have a gridview control, however, when I click the page number, I get an error "Page not found". What am I missing here?
My code is:
<asp:GridView ID="gvEmployeeResults" Width="900px" CellSpacing="1"
CellPadding="2"
AutoGenerateColumns="false" OnRowDataBound="gvEmployeeResults_OnRowDataBound"
runat="server" AllowPaging="true" >
<Columns>
<asp:TemplateField HeaderText="Last Name, First Name" ItemStyle-Wrap="true" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="left">
<ItemTemplate>
<asp:LinkButton id="lbtnEmployeeName" OnCommand="EditEmployee_Command" CommandArgument='<%#Eval("EmployeeNum")%>' CommandName="EmployeeName" Visible="true" runat="server" ToolTip="Click to edit Employee."><%# DataBinder.Eval(Container.DataItem, "empLastName") + ", " + DataBinder.Eval(Container.DataItem, "empFirstName")%></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="empAddrLine1" ControlStyle-Width="225px" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="left" HeaderText="Address" />
<asp:BoundField DataField="empCity" ControlStyle-Width="120px" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="left" HeaderText="City" />
<asp:BoundField DataField="empState" ControlStyle-Width="50px" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="left" HeaderText="State" />
<asp:BoundField DataField="empPostalCode" ControlStyle-Width="100px" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="left" HeaderText="Zip" />
<asp:BoundField DataField="empDOB" ControlStyle-Width="100px" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="left" HeaderText="Date Of Birth" />
</Columns>
</asp:GridView>
protected void BindGridview()
{
corpEmployee.Employee emp = new corpEmployee.Employee();
emp.empLastName = tboxLastName.Text.Trim();
emp.empFirstName = tboxFirstName.Text.Trim();
emp.empDOB = tboxDateOfBirth.Text.Trim();
gvEmployeeResults.DataSource = corpEmployeeMgr.GetEmployees(emp);
gvEmployeeResults.DataBind();
}
protected void gvEmployeeResults_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.Cells[0].Text.Contains("nbsp;"))
{
e.Row.Cells[0].Text = e.Row.Cells[0].Text.Replace("<", "<").Replace(">", ">").Replace("&", "&");
}
}
else
{
return;
}
}
protected void gvEmployeeResults_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvEmployeeResults.PageIndex = e.NewPageIndex;
gvEmployeeResults.DataBind();
}
you must use EnableViewstate= true and bind one time and use IsPostback. (PageIndex )
1. EnableViewState=true for your control
2. In the page load
If(! IspostBack )
{
Bind()....
}
And set PageIndex
