@clarifier Well, it's calling the code behind method every time. However you should pay attention to the implementation of the method. In my approach, you can leave the commandfield as is, then you can hide it as needed via code behind.

If it is expensive, this could easily sum up to a large cost. In this example, I am hiding it if the field "Scenario" of the grid shows the text "Actual" for the relevant row of the Row Data Bound event.

The idea is to only allow a command to be performed on specific people. I'd prefer a declarative solution to a procedural one. For me converting the commandfield to a templatefield control is not an option, as the commandfield comes with built-in functionality that I would otherwise have to create myself, for example the fact that it changes to "Update Cancel" when Edit is clicked, and that when Edit is clicked, all the cells in the row which are labels become textboxes, etc.

In this article I will show you that how you can validate the controls which are inside the Grid View control.

For this I will make the editable Grid View and use the Required Field Validator for the Text Boxes.

Open() Dim cmd As New Sql Command("Select * from stores", con) Dim da As New Sql Data Adapter(cmd) Dim ds As New Data Set() da.

Page Private con As New Sql Connection("Data Source=.; Initial Catalog=pubs; User ID=sa; Password=*****") Protected Sub Page_Load(By Val sender As Object, By Val e As System. Load If Not Is Post Back Then load Stores() End If End Sub Protected Sub load Stores() con.

The Grid View control is a tabular databound control but sometimes it is used like a spreadsheet control. NET 2.0 and is an improved version of the Data Grid control. We can use this to display data from a database and edit, sort and select the data.
