I had a DetailsView control for editing records in a Access 2003 database. I transfered the database to MS SQL 2008 and using the same code does not work - after clicking edit nothing happens (no error) and the record is not updated.
[Code]....
For ASP.NET, I'm using a DetailsView for insert and edit of a record. For edit mode I don't want to display the primary key field because it should not be changed. For insert mode, I want to display the primary key field because it doesn't exist and the user can specify it via a DropDownList that insures they will pick an unique value. A TemplateField is used in the DetailsView markup for the primary key field (hence the DropDownList for insert mode).
My problem is that I cannot get the primary key field to not display for edit mode and to display for insert mode. In the markup I have:
<asp:TemplateField HeaderText="name" InsertVisible="True" Visible="True">
<InsertItemTemplate>
<asp:DropDownList ID="ddl2NonMembers" runat="server"
Width="155px"
Sourceless="sqlNonMembers"
DataTextField="name"
DataValueField="id_adm"
SelectedValue='<%# Bind("member_grp") %>'>
</asp:DropDownList>
</InsertItemTemplate>
</asp:TemplateField>
With the TemplateField Visible="True", the HeaderText="name" always displays which I don't want for edit mode. With the TemplateField Visible="False", the field never displays which I don't want for insert mode.How can I achieve the display behavior I want for insert verses edit mode. I'm fine with changing some property programmatically rather than relying an a pure markup approach,

View 4 RepliesI am trying to "reset" the DetailsView in View1 to ReadOnly mode if the user changes the index in RadioButtonList. Currently, it is working correctly for the first pass and second pass, but fails at the third pass.

How would I go about changing gridview colours and detailsview colours depending on who logs onto my website? Is there a way of doing it in the code behind (basic example follows) :-
If User = "Peter" Then
Gridview/Detailsview Headerstyle =
Gridview/Detailsview Controlstyle =
End If
The gridview and detailsview are connected to SqlDataSource controls and are databound to a SQL server database.
I have a problem that in DetailsView Edit Mode, if I go to edit fields, and set a fields visible property to false, when I update the record through the built in update options it sends a null value. If I change the field back to visible, it passes the data just fine.
Consequently, I tried just setting the field to Read Only = True, and got the same result even though the current values do show up in the edit mode, just read only.Is there anyway to hide the field but still allow it to pass the data it currently has "BACK" into the record.
I have a detailsview control linked to a SQL DB. I have created a template field with various controls within. When I click on edit and change the values and press update. The detailsview control changes back to read only and displays the original values. I have attached the code for the control and datasource below.

View 2 Repliesi have a webform to take user inputs. i am able to insert the data into database on clicking add button and also able to view the

Now when i click edit button, i want the selected record from the detailsview to be populated in the first webform where i can update the record. also deleting record using delete button.i am using c# code,datatable and oracle stored procedure here.
I have created two dropdown lists. The 2nd DDL depends for values on the 1st DDL. I have written code on the SelectedIndexChanged event of 1st DDL to change values of 2nd DDL. also i have used detailsview. In the template field i have used 2 DDL mentioned above. they are having SelectedValue='<%# Bind("") %>' property. Everything works fine but when i tried to edit record in detailsview & select value from 1st DDL then it gives me following error.

I have a table that has previous data in it.
I have written a new site around this data
On occation a user will attempt to edit a record in a detailsview and they get this error:

This happens to be a list of states.
Is there way to allow the edit so the user can select a valid state from the list?

Now when i click edit link i want to grab the selected row id and pass it as querystring or something like that to another page.
