Next event is the Grid View Row Editing event to give ASP. You need to set the Edit Index property of the Grid View with the New Edit Index property of the Grid View Edit Event Args class.If user clicks the Cancel button while Grid View is in editing mode, you need to Cancel the Editing process and also need to reset the Edit Index property to -1 in the Row Canceling Edit event of the Grid View control as shown below: The last step is to handle the Row Updating event to actually update the back end database.These properties will automatically render Edit, Update and Cancel buttons inside Grid View column.I am using Template Field’s Item Template and Edit Item Template for providing read only and editing interface of the same column in the Grid View.I have the following code below in my Grid View1_Row Updating event. Maybe after midnight today, or sometime this weekend. When I go to configure the datasource for my Object Data Source, on my first screen where I designate the business object, my dropdownlist is blank. Turns out getting the DAL, BLL, and the Object Data Souce in place, did the trick. Tracing the code, using both methods above, the value of the textbox is not being passed back; it doesn't appear in the newvalues either. That probably needs to be linked into the Object Data Source along my Get Products, as well as the Add Products, and Delete Product methods. Problem is, I don't have the time at the moment yet. And back to my original question, how to I get the new value? I have a gridview, go into edit mode, enter a value in a textbox, then click update.
In the above tutorial I tried to give you one of the easiest solutions and I hope you can go explore Grid View control editing further after learning the basics from this tutorial.
This collection only requires the row index no and it will give us the primary key.
Last line of the following code is calling a local method for updating the database and passing all the parameters to this method.
In this tutorial we are searching for our Text Box controls txt Product Name and txt Unit Price.
To get the Primary Key reference we can use the Data Keys collection of the Grid View.To do this we first need to obtain the reference of the current row by using its index no as shown in the first line below.
