Error while paging in Gridview: "Index was out of range."

Hi everyone, I have got an error "Index was out of range. Must be non-negative and less than the size of the collection." while paging in Gridview.

I tried to get value from a hidden Label while paging and this error happened. Please help me, thank you.

"GridView2" runat="server" ForeColor="#333333" AllowPaging="True"
AutoGenerateColumns="False" DataKeyNames="id" PageSize="1" CssClass="table table-striped table-bordered table-hover"
OnPageIndexChanging="GridView2_PageIndexChanging" OnRowCancelingEdit="GridView2_RowCancelingEdit"
OnRowDeleting="GridView2_RowDeleting" OnRowEditing="GridView2_RowEditing"
OnRowUpdating="GridView2_RowUpdating" OnRowDataBound="GridView2_RowDataBound">
"id" ItemStyle-CssClass="" HeaderStyle-CssClass="" FooterStyle-CssClass="" />
"" HeaderStyle-CssClass="" FooterStyle-CssClass="">
"lblFruitCategoryID" runat="server" Text='<%# Eval("fruitCategoryID") %>'>
"" HeaderStyle-CssClass="" FooterStyle-CssClass="">
"lblFruitSubCategoryID" runat="server" Text='<%# Eval("id") %>'>
"Center">
"imgFruitImage" runat="server" Width="100px" Height="100px" />
"imgEditFruitImage" runat="server" Width="100px" Height="100px" />
<%--"imgEditFruitImage" runat="server" Text="">--%>
"fileEdit" runat="server" CssClass="btn btn-blue-2" />
"Sub fruit category">
"lbSubFruitCategoryName" runat="server" CommandName="view" CommandArgument='<%# Bind("id") %>' Text='<%# Bind("subFruitCategoryName") %>'>
"txtEditSubFruitCategoryName" CssClass="form-control" runat="server" Text='<%# Bind("subFruitCategoryName") %>'>
"Fruit category">
"Label1" runat="server" Text='<%# Bind("categoryName") %>'>
"ddlEditCategoryName" CssClass="form-control" runat="server">
"60px">
"btn_Edit2" runat="server" Text="Edit" CommandName="Edit" CssClass="btn btn-blue-2" />
"btn_Update2" runat="server" Text="Update" CommandName="Update" CssClass="btn btn-blue-2" />
"btn_Cancel2" runat="server" Text="Cancel" CommandName="Cancel" CssClass="btn btn-default" />
"100px">
"LkB11" CssClass="btn btn-danger" runat="server" CommandName="Delete">class="fa fa-trash-o"> Delete
"#009b97" Font-Bold="True" ForeColor="White" Height="35" />

And code behind for Paging is:

protected void GridView2_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView2.PageIndex = e.NewPageIndex;
Admin_BO_Fruits obj_Admin_BO_Fruits = new Admin_BO_Fruits();
Label lbl = (Label)GridView2.Rows[e.NewPageIndex].FindControl("lblFruitCategoryID");
obj_Admin_BO_Fruits.Admin_BO_FruitCategoryID = Convert.ToInt32(lbl.Text);
GetAllSubFruitCategoryByFruitCategoryID(obj_Admin_BO_Fruits);
//GridView2.DataBind();
}
