We’ll start with binding data to the Grid View, then build up functionality from there.
First, we’ll implement a method to databind the Grid View, which will be called whenever databinding needs to be performed.

If you are not familiar of binding the Grid View the way then I would suggest looking at my previous example first before you proceed to this example. Parameter name: index Any idea what I need to do to fix this issue?
In this demo, I presumed that you already have a basic background on how to create a simple database table. Thanks that cmd do not work fine string id = Grid View1.
In Code Behind you have to do a bit of work though if you want to retrieve the proper context from a Data Item.
Here's some code that needs to retrieve a Pk of one of the bound items and then perform some work on the data (in this case the business object): This seems like a lot of code to have to write just to retrieve data context.
In my code I tend to write the databinding logic as part of the page logic which usually is just a couple of lines of code.
Anyway, the problem isn't that it can't be done 'manually' - but rather that there are a myriad of ways that you can hook up custom link/command processing and they are all similar but yet quite different.
The code first has to retrieve the Grid View Row, which is done by retrieving the Command Argument which in this case a row index of the rendered grid view items.

Contol)Text; it werk just Fine any comment and thx for the code Instead of adding a Customer ID to your table and later pulling the text to get the ID number, a more reliable way to do it is to add a Data Key Names field to the grid example in the page: You can then access this information at any time with the following in code: Grid View1. Row Index]["id"]); You can do this with any field, but I've found customers get confused when they see the ID field and kept asking me why it was there, this also eliminates any issues if you change the display order of your table later (maybe add an edit/update/cancel control) Hey...great article ;)But I got a problem... So here I go with my example:protected void Grid View1_Row Updating(object sender, Grid View Update Event Args e) and the debugger says: Exception Details: System.
The Grid View does know the events that should be used to implement them, so the exceptions shown above are thrown when you try to perform one of these operations, but you have implemented the appropriate event handler.
The example shown here is for a Grid View, but the same types of event handlers must be implemented in roughly the same way for other data controls including the Form View, Details View, and List View. This is the final Grid View markup, so you can see the event handlers we’re going to implement.
In addition to that I will also explain how to add multiple Command Arguments to Control in Grid View and retrieve the same.
