Delete not working all the time.

From time to time i am getting this error when attempting to delete a file. Exception Details: System.IO.IOException: The process cannot access the file 'D:\gallery\images\Untitled-1.jpg' because it is being used by another process. And the times i see it most is if i upload the image and then within seconds try to delete the image. Is there anything that can be done on my part to help prevent this? 

XML with PrimaryKey values to delete rows in database table at a time



I'm having a gridview in my aspx page with checkbox, User can select one or more than one record(s) at a time and clicks on delete button, Then i'm constructing an object of my DTO and adding all the checked row's Primary Key (DataKeyNames - GUID's in my case) to a serializable class and generating an XML and sending it as parameter to the Stored Procedure.

My Doubt is, can i bulk delete all the rows from database table those are present in my XML document??

If it works, I can do bulk update with XML only, i already did bulk insertion by generating an XML..

My Another Question is, Will it affect the performance? Each time when i construct an DTO object and adding it to the Generic List??

WHich one is better, I mean ObjectDataSource or SQLDataSource or my XML method??

Can anyone please help me out clarifying my doubts and also XML Delete Query..


My XML will be like this











Will bulk delete happen in the above case?

Adding Dynamic Rows in ASP.NET GridView Control with TextBoxes and with Delete functionality

In my previous examples, I have demonstrated on how to add dynamic rows in GridView control with TextBoxes and how to save the values into the database. Now, seems that most of the developers are asking if how to add a delete functionality with it. So in this example, I'm going to show on how to delete a certain row in the dynamic GridView with TextBoxes.

SqlCommand.ExecuteNonQuery() returns -1 when doing Insert / Update / Delete

Sometimes you end up with a return value of -1 when using the SqlClient.SqlCommand.ExecuteNonQuery method.

Why is that?

Well, the ExecuteNonQuery method is there for statements for changing data, ie. DELETE / UPDATE /INSERT, and the returned value are the number of rows affected by that statement.

When checking the documentation we can see that there are some conditions that return -1.

For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command.

When a trigger exists on a table being inserted or updated, the return value includes the number of rows affected by both the insert or update operation and the number of

rows affected by the trigger or triggers. For all other types of statements, the return value is -1. If a rollback occurs, the return value is also -1.

Delete not working on List.aspx - out of box



I'am trying to use Dynamic data web site on my project. I have Visual Studio 2010 enf Framework 4.0. I create the default project with the wizard. I add my own Entity Data Model.

When I try to use the "delete" autogenerated button on List.aspx, on the table ServerSetting (see image below), I receive a null exception.  I have no custom code involved in this operation and cannot seem to determine what is Null.

Any help would be appreciated!

Delete spaces created by combining 2 fields


Howdy, this is kind of a continuation of an answer I got from this thread:  http://forums.asp.net/t/1592766.aspx

My users will enter a city/station where an incident occured, and the date.  The trigger below does work, but it will occasionally put spaces between the citystation and the date.  I think this happens when the citystaion name is not very long, but not sure.

(ex: city____08242010)

How can I make sure that if the incidentid is going to have spaces, that sql deletes those spaces?  I need the id to be space free.

wss2.0 update/delete/hide lookup column that does not display any values


Hi All,

I have a document library that contains a Category column that is a lookup field. This is a default column that is a required field when uploading documents to the document library. The Category column is empty and I am unable to amend, hide, make it not required or delete it.

I have gone to Modify settings and columns -> clicked on the Category field to edit, but there is no option to amend the content or delete it. I am only able to amend the Column name and Description.

Since then, I have amended the column name to eg. Category1 and created a new Category field as a lookup and linked it to the correct list.

The problem I am facing now, is that I cannot hide, delete or make the Category1 (old Category) field NOT required. Either I would like to update the original field to display the correct values or alternately hide, delete or make the column not required.

Please help.

ReadOnly DateTime attribute stores correct date but only retrieves DateTime.MinValue on Delete


Hey everyone,

I have a dynamic data site that stores Event data using LINQ-to-SQL. When someone requests an event, it is first stored as a PendingEvent (which is a child of Event) with a column/attribute called receivedAt, which is [ReadOnly(true)] and which is assigned in InsertEvent as shown.

        partial void InsertEvent(Event instance)
            instance.requestedAt = DateTime.Now;




This works fine. The event displays with the correct receivedAt date, and it's correct in my database. It shows up just fine on my Display, Edit, and List pages. However, if I try to delete, the receivedAt in the instance (retrieved with my debugger) in my delete function is 01/01/0001 12:00am, also known as DateTime.MinValue. My other dates appear correct.

If I remove "ReadOnly(true)" from the received at, everything works fine. Why won't "ReadOnly" allow me to have a time?
Thanks in advance,



I forgot to mention why I care. I can't submit the instance to be deleted because DateTime.MinValue is outside SQL's available datetime, so I get a SQL error. The delete also takes place in a custom dele
