Forms Data Controls :: Deleting From GridView Without Call Datasource's Delete Command
Jan 21, 2010I'm using the asp.net membership on my website. On the User Administration page i've got a GridView to show the details of the users on the site. As a datasource rather than just using the Membership.GetAllUsers function i've got a SQLDataSource as i need to display user information from 3 different tables. I'm trying to add a delete button to the GridView. I'm setting the Membership's UserName as a DataKey and then using the RowDeleting event to call Membership.DeleteUser for the appropriate UserName. This works fine and the user is deleted however i then get an error showing up that "Deleting is not supported by data source 'SqlDataSource1' unless DeleteCommand is specified."
I don't want to use the SqlDataSource for deleting as i've already done it using the Membership. How can i stop it from trying to do this? Here is the cut-down that i have if you're interested. The selectcommand in the sqldatasource was auto-generated by it.

DataSource Controls :: Deleting Data From The Multiple SQL Tables With LINQ (C#)?
Apr 22, 2010I'm looking for ideas on deleting data from the multiple SQL tables with LINQ (C#).
My existing solution does the following:
1. DeleteAllOnSubmit( Subset of the data from the child table)
2. DeleteAllOnSubmit( Subset of the data from another child table)
3. DeleteAllOnSubmit( Data from the parent table)
4. CommitChanges()
All this resides within a single method, which makes it ugly and not re-usable.
I have considered the following alternatives, but I decided not to use them:
1. Cascade delete on the tables.
2. Do a join on all tables from which I will remove the data, but I'm not sure yet whether I could pass a join query to DeleteAllOnSubmit().
3. Write stored procedure(s) to delete data from each table. I don't have the time to implement this due to a large number of tables and the time constraints.
Forms Data Controls :: DetailView & DropDown?
Mar 19, 2010I 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?

Forms Data Controls :: Linking Detailview To Gridview?
Feb 18, 2010I'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?

View 5 RepliesForms Data Controls :: Checking For Updated Information In DetailView Control?
Jan 6, 2011I 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.

DataSource Controls :: Entity Framework Deleting Many To Many Relationship?
Jul 9, 2010I have 3 tables User, role and UserInRole THe entity frame work made entities for User and Role and I have successfully made a join with the user and role entities using user.add(role); but I can't seem to get it to remove the link (I want to retain the user and role just remove their association).
using (ProviderEntities context = new ProviderEntities())
{
User u = context.User
.Where(n => n.ApplicationName == application)
.Where(n => n.Username == username).First();
Roles r = context.Roles
.Where(n => n.ApplicationName == application)
.Where(n => n.RoleName == roleName)
.First();
r.User.Remove(u);
context.SaveChanges();
}
The oposite worked when I did r.User.Add(u); but it wont let me now remove it after it been created. Driving me mad as I can't see where I have gone wrong.

View 2 RepliesForms Data Controls :: Update Dropdownlist With Detailview Control - Set Update Parameters?
May 10, 2010I 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.

Forms Data Controls :: GridView Deleting?
Sep 21, 2010I am using VS2005 and SQL Server 2005. The problem I am having is when I call my SQLDataSource to delete rows the delete is firing twice. The trace and debugging show the code executing once. In fact right after the delete, the table only shows one delete, but right after the command function is exited the 2nd row is deleted. Also, I have tested the stored procedure to make sure it only deletes 1 one and then resequences the records.Show below are excerpts from my .aspx and code behind files.
