Select * from Table -> works
Delete from Table -> throws error about no instance instantiated
I need to execute a stored procedure which is a simple delete (record) query. Programmaticaly, I want to pass in a parameter "ID1".
Assume I will pass in the ID1 parameter on a delete link click event froma GridView control. What would the code be to execute the existing stored procedure?
ID1 - the parameter and primary key of the source database for the record to be deleted
GridView1 - the GridView control
spDeleteRecord - the stored procedure needing the parameter ID1 and to be executed from C# code
Here's my start:
protected void GridView1_RowDeleting(object sender, EventArgs e)
TableCell cell = GridView1.Rows[e.RowIndex].Cells;
int ID1 = System.Convert.ToInt16(cell.Text);
??? - code here to call and execute parameter query
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.

So in this example, I'm going to show on how to delete a certain row in the dynamic GridView with TextBoxes.

Creating UI controls on the fly can be accomplished via run-time code generation. And there are lots of reasons to do so. Generating these controls once and then reusing them as needed is more efficient than generating the controls each time. Read on.

In a shared environment you typically don't have access to delete your database, and recreate it for fresh installs of your product.
I managed to find these scripts which should help you clean out your database.
Use at your own risk.

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!

Howdy, this is kind of a continuation of an answer I got from this thread:
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.
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.
