I'm trying to sort a GridView that has 6 columns that are databound by a DataSet. All of this data is being called through a stored procedure. I've looked through the different posts and tutorials out on the interweb and finally got what I thought would be the best one for my page. But with this one, I keep getting an error,
Exception Type: System.IndexOutOfRangeException
Message: Cannot find column LoanOfficer
I'm open to help on this method or even suggestions a different way to tackle sorting.
Here is my code:
ASPX
<asp:GridView ID="dgvBranchChange" runat="server" AutoGenerateColumns="False" AllowPaging="True"
CssClass="ReportDataGrid" HeaderStyle-CssClass="DataGridHeader" RowStyle-CssClass="AccentShade"
AlternatingRowStyle-CssClass="NoShade" SelectedRowStyle-CssClass="AccentLvl3"
PagerSettings-Mode="NumericFirstLast" PagerStyle-HorizontalAlign="center" PagerStyle-CssClass="paging"
Width="100%" PageSize="25" AllowSorting="True" ShowHeaderWhenEmpty="true" OnSorting="dgvBranchChange_Sorting">
<AlternatingRowStyle CssClass="NoShade"></AlternatingRowStyle>
<Columns>
<asp:TemplateField HeaderText="LoanOfficerID" Visible="false" SortExpression="LoanOfficerID">
<ItemTemplate>
<asp:Label ID="lblBULOID" runat="server" Text='<%# Eval("LO_ID")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="LoanOfficer" HeaderStyle-HorizontalAlign="Center" SortExpression="LoanOfficer">
<ItemTemplate>
<asp:Label ID="lblBULOName" runat="server" Text='<%# Eval("LO_Name")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Branch_NameID" Visible="false" SortExpression="Branch_NameID">
<ItemTemplate>
<asp:Label ID="lblBUBranchID" runat="server" Text='<%# Eval("Branch_ID")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Branch" HeaderStyle-HorizontalAlign="Center" SortExpression="Branch">
<ItemTemplate>
<asp:Label ID="lblBUBranchName" runat="server" Text='<%# Eval("Branch_Name")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Move_Begin_Date" HeaderStyle-HorizontalAlign="Center" SortExpression="Move_Begin_Date">
<ItemTemplate>
<asp:Label ID="lblBUBeginDate" runat="server" Text='<%# string.format("{0:MMM yyyy}",Eval("Begin_Date"))%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Move_End_Date" HeaderStyle-HorizontalAlign="Center" SortExpression="Move_End_Date">
<ItemTemplate>
<asp:Label ID="lblBUEndDate" runat="server" Text='<%# string.format("{0:MMM yyyy}",Eval("End_Date"))%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="User_who_Added_Change" HeaderStyle-HorizontalAlign="Center" SortExpression="User_who_Added_Change">
<ItemTemplate>
<asp:Label ID="lblBUUserId" runat="server" Text='<%# Eval("User_ID")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Change_Date" HeaderStyle-HorizontalAlign="Center" SortExpression="Change_Date">
<ItemTemplate>
<asp:Label ID="lblBUCreationDate" runat="server" Text='<%# string.format("{0:MM/dd/yyyy}",Eval("Create_Date"))%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:CommandField ButtonType="Link" HeaderText="Remove Change" ShowDeleteButton="true"
DeleteText="Remove" />
</Columns>
</asp:GridView>
Code Behind
Protected Sub dgvBranchChange_Sorting(sender As Object, e As GridViewSortEventArgs)
'Retrieve the current table
Dim dsBranchChange As DataSet
Dim asParams(0) As IDbDataParameter
Dim lDB As New RHubCoreFunctions.RHubDB
asParams(0) = lDB.dpCreateDataParameter("@AccountID", DbType.String, 8, AccountSelected.AccountID)
dsBranchChange = lDB.GetDataSet("ssp_Account_LO_Branch_Change", asParams)
Dim dt As DataView = dsBranchChange.Tables(0).AsDataView
If dt IsNot Nothing Then
'sort the data
If (dgvBranchChange.SortDirection() = SortDirection.Ascending) Then
dt.Sort = e.SortExpression & " ASC"
Else
dt.Sort = e.SortExpression & " DESC"
End If
dgvBranchChange.DataSource = dt
dgvBranchChange.DataBind()
End If
End Sub
EDIT: I found out that I was using the wrong SortExpression. I was using the same one as the header text as thats what was given in pretty much all the walkthroughs/tutorials. But it has to be the same name as the column name from the table that you're getting the data from, i.e the SQL table.
But now I can only sort the first column in Ascending, nothing more
