Ok let’s move on to Code behind what we have to do when user clicks Edit, Delete, Update and Cancel When we click on Edit the On Row Editing event will be fired.You can see the C# code below will give the row number whatever you are editing by New Edit Index property.

Everything should be sorted out when the “Update” link is pressed.

So Grid View will put the appropriate row into the Edit Mode by assigning row number to its Edit Index property. You can follow any responses to this entry through the RSS 2.0 feed.

Then again we have to call that Bind Grid Data () method to bind data for the textboxes. You can leave a response, or trackback from your own site.

So once after done with editing data, if we click update the following method will be triggered. Once we access the required fields in the code behind, we need to update the data in the database and show the updated data to the user. If the user clicks the Delete button On Row Deleting event will be fired. Going into that code we are trying to get the primary key of the employee table(Employee ID) by using Grid View Data Key Names and then This entry was posted on March 27, 2009 at am and is filed under ASP.

So am calling the method Bind Grid Data method which is overloaded .

If you have more than one primary key, you can separate the values with a comma.

In the template field I will Place a label or some controls, So that it’s very easy to access those controls in the code behind by using Find Control method. Item Template is the content to display for the items in the Template Field.

Run the project and place a breakpoint on the code above. The program will stop on the breakpoint and you will be able to see the selected row index being passed through.

You can then use the code below to retrieve the ID value: are a great way to use primary keys without having to display them to the user.

In case of the bound field’s we need to check what column it is and need to use index of that cloumn, which is little hard and even in future if we change the column order If you see the Last Template Field part in the above code, I am using the link buttons for edit, update, delete and cancel.

May be you may think why am I using link buttons as we are provided with some command field buttons by Grid View.

I suppose my eyes got big when I saw all the new properties and methods, and wanted to try them all out. Most articles I found were for hardcoded datasources (especially on MSDN, ugh) and didn’t really help me much, so this post will be referring to Grid Views with dynamically bound datasources.
