Community Server Library - Deleting A User?

Oct 9, 2009

I have been asked to fix a Community Server forum where thousands of users were created via a script. All of their profile pages are SEOspam for prescription drugs, etc. The forum was not using email verification or admin approval for newly registered users. I turned on the latter for now, but captcha would be nice.

My problem is that it is very cumbersome to mass delete these accounts. I set up a .net grid (Telerik Radgrid actually) so that I could mass select users and click delete. However the following code does not seem to be working (mind the VB nubbery):

Protected Sub rgUsers_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles rgUsers.NeedDataSource
rgUsers.DataSource = Users.GetUsers().Users()
End Sub

[code]....

The UserDeleteStatus result returns 'Success', however the user is not actually deleted. Am i using the correct delete function?

Deleting Bound Item From DataGridView?

Oct 18, 2010

I have a List of an object, set to DataSource of a BindingSource, set to DataSource of a DataGridView. Then I added a DataGridViewButtonColumn which I want a click to remove that record from the collection. So I simply call collection. RemoveAt (e.rowIndex) from the DataGridView CellClick event. However this produces an IndexOutOfRange Exception; "1 does not have a value"..

So is happening here? I have maybe a vague idea, but would like to understand exactly which events are failing etc.. and what do i need to do to perform this action properly?

EDIT: This seems not to happen if I use a BindingList.. But when using a List, I get this problem..

DataGridView - Deleting Successfully Inserted Rows?

Jul 30, 2010

How would I delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If I dont delete the successful rows then I will have multiple inserts of the same dataRow and we dont want that! And if I don't move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic I am trying to perform at the bottom of my code, right after I insert into the database.

Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click
'Function declarations
'Object declarations
Dim localOutputServer As SQLServer = Nothing
'Variable declarations (Form)

Deleting From A Cascaded DataGridView Populated Via Linq To SQL?

Nov 18, 2009

I am having problems deleting any rows from a cascaded DGV. I get a run time error complaining that I am breaking a constraint almost as if LINQ is try to delete from the parent table. I have 2 DGVs on a form one displaying Species and the other all SubSpecies for the currently selected species and that works fine.

However when I try to delete a SubSpecies I get the following exception:- An attempt was made to remove a relationship between a Species and a SubSpecies. However, one of the relationship's foreign keys (SubSpecies.SpeciesID) cannot be set to null. At first I thought the error was raised by SQL server due to the Cascading Delete limitations on L2S but the error message for that is very different the DataContext.Log doesn't show any attempt to change the data.

The code used to bind the DGV's is as follows:-

Protected Sub BindControls()
Try
DC = New DataClassesWhatToPlantDataContext
