Rowupdating event in gridview in asp net

Simple Insert, Select, Edit, Update and Delete in Asp. – The above block of codes in Row Updating event, finds the control in the Grid View, takes those values in pass it to the Customers Cls class Update method.

the good old problem of getting the data from the row that is being currently edited within a Grid View. Accessing the "Controls": This method gets you access to the control in the Grid View, which might be useful based on what you are doing.

A couple of days ago I mentioned a project that I’ve been working on that is a bit out of the ordinary as far as Grid Views go.

One of the issues I’ve had is that the edit template doesn’t map to the view template very well. You see, the data that gets stored back to the database during the edit could go to two of four different tables.

The problem is, I’d very much like to do so, if ASP. But I can’t set a Data Source property or anything on the Sql Data Source!!! I probably have to read the cells on the Grid View of the selected row, find the controls, get the values from those and insert those into my Data Set.

On Row Deleting - can call registered event handlers" I couldnt figure out how to continue this thread, but the issues in it are related so i'm including it as a reference.

For example a Sql Data Source, which is automatically added to your Web Form if you drag-n-drop your way around Visual Studio 2005.

But for this demo, I’ll show you the simple version, that also doesn’t work 🙂Let’s bind the data to our Grid View and have it autogenerate our columns, as well as an edit button.

When we edit a row in our Grid View and press the “Update” button, at some time it’s received in the Row Updating method.

Note A common mistake that a lot of people do is that they perform a databind each and every-time the Page_Load method is called.

This will lead to problems like "Grid View does not show updated values", "Grid View looses values changed by user". In your Page_load, this is typically only inside a block where you check to make sure that Page_Load is not being called during a post-back call.

Enable Callbacks property is set to "true" Post Data is applied automatically before required events. I guess it is because the Html Edit Form Created code initializes the editform controls with the old values from the gridview. If your scenario is different, please feel free to modify my sample to illustrate your approach. Please refer to the Dev Website Terms of Use for more information.
