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:
System.ArgumentOutOfRangeException ddlState has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
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?

I have a DetailsView within an UpdatePanel. I programmatically put the DetailsView into edit mode, change the fields then call the UpdateItem method which causes the "must be in edit mode to update a record" exception. Am I missing something blindingly obvious?

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.

Scenario : I have two database tables with one to many relationship. eg:- City and Related news. So I have a gridview(Gridview1) which lists out all the cities and allows edit, delete of the gridview rows. Now since i wanted to display all news for the city, i have a nested gridview as a column in this Gridview1. This nested gridview displays all the news for the cities. And I have edit, delete buttons for this gridview too - So far, good - works fine.
Now what I would like to do is - To insert a new news item for a city. For this, I attached a detailsview to my nested grid(gridview2), and tried to insert. I need the primary key id of city table from the first grid (gridview1) to insert the news into the second database table and I could not access this value from the parent gridview. My gridview1 does not have datakeyname, it is programatically bound.
Also, When the gridview/detailsview is nested, it does not get listed in the event-handler list. So I cannot use say, detailsview1_iteminserting. I do not how to add this event handler
Has anybody done anything similar? When I started, it looked like a pretty straightforward thing - There must be some way to do this. But I just can't get it to work. How do you usually insert into the child table in a one-to-many relationship? Should i just be using two separate gridviews?

How to set my DetailsView to show a specific record for I which catch it's datakey from a text box ??
DetailsView is already bound to a datasource (in this case from an Access database file):
[Code]....
The "SqlDataSource1" uses a connection string "nwind" set in web.config.
I would like to do this in C# (code behind) and I store the "datakey" in a "s" string variable. After this I'm lost..

I want to update a record in a detailsview which contains a decimal value which I would like the field to formatted as currency while editing.
When I try to update the record I get an error about trying to pass a formatted value to an unformatted table column. The ApplyFormatInEditMode is set to true and you are cautioned by intellisense about unformatting befor updating the record. This is databound field.
Is this a simple as x = Val(detailsviewrow(1).tostring) ?
Here the code I am trying :

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.
Server Error in '/' Application. Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

I am trying to handle the detailsview programmatically but I don't know what I am doing wrong. My details view control isn't going into edit mode. My code for my gridview's select button properly loads the data into the detailsview but once the detailsview renders clicking on "Edit" doesn't switch the detailsview contol into edit mode.
This code draws the information from my database and loads the information into the dataview:

This code is in my dvTeamDetails_ItemCommand sub and the beep works:

This code handles my mode changing event:

Here is some of the HTML code:

I am currently binding my Detailsview and Gridview together by a "ID" field selectedvalue "1". Which works great except for the fact that I don't want the user to have to go down to the gridview and select the page and then the record to view it in the detailsview.
I have 1 sqldatasource for detailsview and another sqldatasoure for the gridview. Both have the exact same select statement.
I want the gridview and detailsview to automatically display the last record inserted not the first record in the table.

This would seem to be quite a trivial task, however I am having trouble retrieving the identity of the record inserted using the detailsview.insert() in the code behind. It would seem that detailsview.DataKey.Value would contain this value, but it is null after the insert is performed.

I have a GridView and DetailsView on the same page. If the GridView has data, I can Select a row and it brings up the DetailsView from which I can edit that record or click NEW to create a new record. Without a record to Edit, the New link and the DetailsView control is not visible. What is considered best practices for Inserting the 1st record using a same page Gridview / DetailsView combination?

after a DetailsView (DV) 'Insert' (triggered by a DropDownList (DDL)) the DV shows the first record (in the DDL)!Are there VS2008 means to keep / show the just entered data - again ready with the command row "Edit/Delete/New" enabling me to e.g. "Edit" the just entered data?This DDL/DV scenario works just fine but to show my just entered record I have to leave this page and start calling this .aspx page again in order to see the name in the DDL and, hence, in the DV.I.e. I'm looking for a kind of automatic 'postback' bringing my just entered data back

I have a SQL DB with just 2 fields, ID and TEXT.What i was trying to do, was placing a Detailsview in EDIT MODE, then selecting from the DB like SELEC TOP 1 Text FROM DB.Then i placed a Ajax HTML Editor in the template field.How can i, keep the HTML Editor on the page, and use it for INSERT and/OR EDITING ?e.g.: on the first time the user opens the site management page, it will be blank, so it will show the HTML with no text on it. but the bottom button will be UPDATE and CANCEL. So when he enters the TEXT he clicks on UPDATE.
