I have a User object with a Load method that takes in a UserId parameter and loads that users data to the objects member variables.
Now what I'd like to do is load this data to a DetailsView control using an ObjectDataSource, but I'm stumped as to how.
First of all, I'm not sure I've got the code set up properly to pass the parameter (UserID) to the SelectMethod (cUser.Load). Secondly, I don't know how I can load this data to the DetailsView since I'm not actually returning the results from the Load method, I'm simply loading the object with the data...here's my code..
<asp:GridView runat="server" ID="gvUsers" DataKeyNames="UserID" BackColor="#eeeeee" Width="85%"
HorizontalAlign="Center"

is there a way to do what I'm trying to achieve? if so, can you please give examples with the explanation?
Very much appreciated. Thanks

I'm building a GridView based on what is passed on the previous page querystring.
Is there a way to display a message saying 'no records found' if the GridView isn't populated? i.e. the query produces no records to populate the GridView.
code:
<div class="centergrid">
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1" CssClass="bookgridview">
<Columns>
<asp:TemplateField HeaderText="Choose">

<asp:HyperLink ID="lnkSelect" runat='server' NavigateUrl='<%# String.Format("~/bookingform.aspx?ID={0}", Eval("ScheduleId")) %>'>Book</asp:HyperLink>
</ItemTemplate>

<asp:BoundField DataField="TName" HeaderText="Name" SortExpression="TName" />
<asp:BoundField DataField="SDate" HeaderText="Date" SortExpression="SDate" DataFormatString="{0:d}" />

Is there a way to display a message saying 'no records found' if the
GridView isn't populated?
Yes, with the EmptyDataTemplate.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1" CssClass="bookgridview">
<emptydatarowstyle backcolor="LightBlue"
forecolor="Red"/>
<emptydatatemplate>

imageurl="~/images/Image.jpg"
alternatetext="No Image"
runat="server"/>
No records found.
</emptydatatemplate>
<Columns>
<asp:TemplateField HeaderText="Choose">
<ItemTemplate>
<asp:HyperLink ID="lnkSelect" runat='server' NavigateUrl='<%# String.Format("~/bookingform.aspx?ID={0}", Eval("ScheduleId")) %>'>Book</asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="TName" HeaderText="Name" SortExpression="TName" />
<asp:BoundField DataField="SDate" HeaderText="Date" SortExpression="SDate" DataFormatString="{0:d}" />
<asp:BoundField DataField="STime" HeaderText="Time" SortExpression="STime" />
<asp:BoundField DataField="TPriceadult" HeaderText="Price (Adult)"
SortExpression="TPriceadult" DataFormatString="{0:C}" />
<asp:BoundField DataField="TPricesenior" HeaderText="Price (Student/Senior)"
SortExpression="TPricesenior" DataFormatString="{0:C}" />
<asp:BoundField DataField="TPricechild" HeaderText="Price (Child)"

SortExpression="TDuration" />
<asp:BoundField DataField="ScheduleId" HeaderText="ScheduleId"
SortExpression="ScheduleId" Visible="False" />
</Columns>
</asp:GridView>
Alternatively, you can use the built-in UI for the empty data row by setting the EmptyDataText property instead of this property.
I was assigned to convert some .Net projects in old version to to .net 4.0 version. I used ODAC driver replacing ODBC driver. Everything went fine until I found a problem with a gridview were I get illegal character Oracle exception when I try to delete a row. The gridview is inside an update panel. The exception I receive is Microsoft Jscript run time error:Sys.WebForms.PageRequestManagerServerErrorException: ORA-00911:invalid character. The following is the code for the grid view and the sqldatasource. The linkbutton triggers the delete using the deleteparameters of the sqldatasource.

I found an easy alternative using row-deleting event of the grid-view. I Just removed the delete parameters in the sqldatasource of asp page and then I set conflict-detection to overwrite-changes.
Sqldatasource1.DeleteCommand = "DELETE FROM code_owner WHERE code_owner_ID = :original_code_owner_ID"
Sqldatasource1.DeleteParameters.Add("original_code_owner_ID", GridView1.DataKeys(e.RowIndex).Values("code_owner_ID").ToString)
Sqldatasource1.Delete()
GridView1.DataBind()

Browser fire the confirmation question, but after hittting YES, nothing happens.
It works fine in my computer, nothing happens in the hosting server.
Thanks in advance.
Use asp:Button instead of asp:LinkButton
I'm trying to connect my gridview to a LinqDataSource to select, update, insert and delete records. I am able to get into edit mode and cancel out of edit mode but when I click update nothing happens.
I've found a few things online that say to check the "Enable Editing" box in the gridview smart tag but when I go into the smart tag the only check boxes that appear are: Enable Paging, Enable Sorting and Enable selection. The others don't appear. Dose anyone see a problem with what I am doing below?

Did you try it without using anonymous types? In code, you can't update anon. types in the database...
Looks like this was caused by me having the Select value set on my LinqDataSoruce. See updated LDS below:

I have a Detailsview object that is loaded with user data when a User is clicked from a gridview. The problem is, I am using a sqldatasource and I'd rather use my pre-exisiting user class which has all the built in functionality for this. I haven't been able to get this done correctly. I can't get the detailsview populated with user data without the sqldatasource, and when I try inserting or updating with my objects, it runs through the insert/update code, then fails afterwards because I don't have a InsertCommand, etc for my SQLDataSource....bottom line...can somebody help me get this working without needing the SQLDataSource?

Not sure the CodeBehind is necessary, I just want to use that to call my data object code for updating, insert etc
Why not use a ObjectDataSource. This control works much like an SqlDataSource but instead of specifying an SQL query or Stored Procedure you specify the methods of your custom business object to perform your data access.
<asp:ObjectDataSource ID="ObjectDataSource" Drunat="server" DeleteMethod="Delete" InsertMethod="Insert" SelectMethod="Select" UpdateMethod="Update" TypeName="YourType">
Here's an example illustrating how to use an ObjectDataSource with a DetailsView.
