how would i do my Gridview delete command like a update command?
im using a datasource... and my delete command is like my update command... so i can change the status into "INACTIVE"...
DeleteCommand="UPDATE ACCOUNT_MAINTENANCE SET am_status = 'INACTIVE' WHERE (accmain_no = @accmain_no)"
UpdateCommand="UPDATE [ACCOUNT_MAINTENANCE] SET [account_type] = UPPER(@account_type), [min_deposit] = @min_deposit, [min_capital] = @min_capital WHERE [accmain_no] = @accmain_no"
when i press my delete command at gridview... the status changed into "INACTIVE" but when i refresh or press f5... it automatically update the status into "INACTIVE" also...

I have one GridView and one "Add" Button. If I click the "Add" button, one new row will be added to the GridView at the sametime I want to show "Update and Cancel" buttons in CommandField Column.
When I click the Update Button after the Insertion of the New Row, I want to Show the Delete Button in the Command Field Column. Once again When I click the Delete Button, the Corresponding row will have to be deleted.
So far I have done all the four things(update, cancel, edit and delete) at the same. But now I dont want Edit. The problem is when I include "ShowDeleteButton = True" in the command field, the "update and cancel" buttons are not displaying when I click the "Add" button.The "update cancel" buttons are displaying only when I include "ShowEditButton = true". But I dont want to Edit the Column.
Here I want only to do Update, Cancel and Delete. How to do? I dont want coding, I have written all the coding parts in Gridview_Rowupdating and RowDeleting Event.
I am trying to search how to select rows from a datatable. When selecting these rows I should be able to delete the row or edit (update) the row.
I am using the following code to load the data from MsSql 2008 to a dataGridView;
DataTable dtTypes = new DataTable(); SqlConnection con = new SqlConnection(Settings.Default.JLTrackConnectionString); SqlCommand cmd = new SqlCommand("SelectJobTrackForDate", con); [code]....
Is there any good article which tackles this because I am searching for the bad keywords I think.

My gridview works fine without the following code, but as soon as i add this, there is a probleme, when i click on delete or update button, i see no change, it's all the same.
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs)
asp.net Code: 'If e.Row.RowType = DataControlRowType.DataRow Then Dim A As Integer A = e.Row.Cells(13).Text.Length If A > 6 Then e.Row.Cells(13).Text = e.Row.Cells(13).Text.Substring(0, 6) End If End If End Sub
I am using a LinqDataSource fed by a stored procedure in my data context for the data source of my grid view in an update panel. The issue I have is that after I get the grid row into edit mode, I can't get it to commit an update. I figure my issue here stems from TableName and EntityTypeName, but am unsure what to do with them. This MSDN page has the following line in the 'Working with Stored Procedures' section: 'If you want to enable automatic update, insert, and delete operations for the data, the type that is returned from the method must match the type that is specified in the TableName property.'
The return type of my stored procedure is 'loadHaveToOfferByUserIDResult' but when I use that for the TableName, I get the following error: Could not find a property or field called 'loadHaveToOfferByUserIDResult' on the data context type 'LINQClassDataContext' of LinqDataSource 'haveToOfferLinqDataSource'.
I just want to be able to create a site that will allow users to insert/update/delete information from the site and the information will be recorded on the SQL DB.

Am running asp.net application with c#.Am using gridview to update and delete the columns.deleting is working fine.if am clicking the update button i got
System.NullReferenceException: Object reference not set to an instance of an object.
I have googled this a little and didn't really find the answer I needed. I am working on a webpage in C# with SQL Server and LINQ for a customer.I want the users to be able to send messages to each other. So what I do is that I unit test this with data that actually goes into the database.The problem is that I now depend on having at least 2 users who I know the ID of. Furthermore I have to clean up after my self. This leads to rather large unit tests that test alot in one test. Lets say I would like to update a user. That would mean that I would have to ceate the user, update it, and then delete it. This a lot of assertions in one unit test and if it fails with updating i have to manually delete it. If I would do it any other way, without saving the data to DB, I would not for sure be able to know that the data was present in the database after updating etc.What is the proper way to do this without having a test that tests a lot of functionality in one test?
for my dynamic user control, i am trying to do any event from that control (delete, update .... etc) but it disappeard when i make any event! this the code in the page to load it dynamically:
