C# - How To Update / Delete And Cancel A Row In Gridview

Mar 11, 2011

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.

VS 2010 LinqDataSource Insert / Update / Delete

Dec 14, 2010

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'.

C# - Unit Test Insert/update/delete?

Mar 18, 2010

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?
