I searched a lot of threads but still couldn't get my problem fixed. I have to update the "regform" table with two fields: session_ and session2. These two fields are inside the detailview edititem template which bounded to dropdown list drpsession1, drpsession2 separately. I wanted to pass the update parameters to the update sql UPDATE dbo.regform SET session_=@session_, session2=@session2 where id=@id
the @session_ is bounded to a drpsession1 and @session2 is bounded to drpsession2. I used
ControlID="ctl00$ContentPlaceHolder1$DetailsView1$drpsession1" to access the dropdown list within the detailview, but still couldn't do the updates. What's wrong with my code? Do I have to use the code behind to specify the update parameters? and How to do it? TIA.

I know you've heard these questions, one million of times:1) I have a profile page with firstName, lastName, address1, address2, etc. and county as a 3 chars countryID, like USA for United States, GBR for Great Britain, etc. How do I connect the countries table (contains countryID and countryName columns) to display United States instead of USA? Of course I also need to update it selecting a country name (not ID) ?2) What will happen when I will need to give the page a more attractive look? Is this DetailView easily convertible in plain HTML form?

I'm trying to link a detailview to a gridview. Both are using the same datasource control and it's coming from an Access database. Both are showing data. The gridview is listing products fine and the detailview is listing details of some default product (maybe the first). How can I configure the two so that when I hit my select button on my gridview that it populates the details into detailview with the correct data for the selected product?

I have a gridview and detailview in an updatepanel. My detailview is setup to display the details of a record that is selected in the gridview. When I edit the values in the detailview and click update it does not update the gridview. If I check my database the values have been changed it just haven't been updated in my gridview. Below is my code for the two objects and their datasources.
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AutoGenerateColumns="False" DataSourceID="RCR_DSM" AllowSorting="True"
DataKeyNames="PartNumber" AutoGenerateSelectButton="True">
<Columns>

I am using a DetailsView control to allow for updating a user record. Is there a way to check if the values are actually updated/changed when the update link is clicked. I know there are users, who would click the update button rather than the "Canel" even if there are no changes to the record. So, how do I check if any value has been updated when the update link is clicked. The DetailsView uses a SqlDataSource to populate the DetailsView.

I have a formview that I open to the edit template, some textboxes are not available and some are populated by dropdown lists, and the update function works fine.
As soon as I add some logic to the code behind page for the update control, the UPDATE link on the formview stops updating my DB.

Here a samplescreenshot:

I know how to bind the columns to a grid and its no problem to create such a dropdown list with the content for me, too. But i dont know how to sort the complete datatabl after changing one value of one dropdown listbox.
So, how can i resort the values of a datatable column based on a given value and the datarow id?
