Gridview onrowupdating event
For demonstration I have created a database (named Database.mdf) in which we have a table named tbl_Employee.
Here Mudassar Ahmed Khan has explained how to Export a Grid View with Images or Pictures to Word Excel or PDF Formats in ASP. In this article the Grid View is displaying images stored on disk and th Hi, This is Mudassar Khan.

@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.
In this article we create a Gridview from database and add some additional operations such a add, edit and delete data in the Grid View control.
In the previous article , we learned how to create a simple Grid View at runtime .
"The most important thing is that I have assigned null to each variable to avoid the effect on the parameter ed to the Stored Procedure because we are ing a different number of parameters but not the same number of parameters to the Stored Procedure to perform these tasks." In the sample code above I have used the two string queries for giving the Stored Procedure name and the constr for storing the connection from the web.config file and another thing is that I have used a hidden field by which I am ing the action values that are required to our Stored Procedure.
Now at page load I have called the method, so after that the grid will fill as in: Now click on the Edit button that calls the edit method as shown in the following grid: If you click on the "Cancel" button then the editcancel method will be called and edit mode will be cancelled.
To do that, instead of creating four Stored Procedures to perform these tasks I will create a single Stored Procedure to satisfy my requirements and I will access it in code behind depending on the action performed by the end user on a button click.
I have written this article specially focusing on newcomers and anyone new wants to insert, update and delete records in a Grid View using a Single Stored Procedure, so let us start with a basic introduction.
Open() ' Dim cmd As New Sql Command(s Update SQL, conn) ' cmd. Add With Value("@Brand ID", Direct Cast(Grid View1.
To String() End If End If End Sub Protected Sub Grid View1_Row Editing(sender As Object, e As Grid View Edit Event Args) Grid View1. New Edit Index Bind_Check Box List() End Sub Protected Sub Grid View1_Row Updating(sender As Object, e As Grid View Update Event Args) Dim s Constr As String = Configuration Manager. Connection String 'Using conn As New Sql Connection(s Constr) ' Dim s Update SQL As String = "UPDATE Product SET Brand [email protected] ID WHERE [email protected]" ' conn.
The comments in the Stored Procedure above clearly explain which block is used for which purpose, so I have briefly explained it again.
