Six of those paramaters basically comes from the Text Box values that were entered in the page. Invalid Cast Exception: Unable to cast object of type 'System.
The last parameter is a boolean value which tells the method whether to execute an Insert (false) or Update (true). In-order to perform Edit and Update in Grid View we need to use three events ( Grid View_Row Editing, Grid View_Row Canceling Edit , Grid View_Row Updating).
May be you may think why am I using link buttons as we are provided with some command field buttons by Grid View.
Please review the stack trace for more information about the error and where it originated in the code.
I am trying to change the value in textbox but after submitting the changed value is not coming. Description: An unhandled exception occurred during the execution of the current web request.
Nor does it represent the opinion of my dog, because I don’t have one. I have a project that I coppied the above code into. Data Keys[Row Index]["Customer ID"]in the Update event it would be something like:int Customer ID = Convert. Format Exception: Input string was not in a correct format.
This demo is a continuation of my previous example “Binding Grid View with Data”. When I do an update, and get to the Grid View1_Row Updating, there is no value passed to "ID", and then when I go to the next row for "Company" I get the following error: Specified argument was out of the range of valid values. Text; bit when ichange it to string id =((Text Box) Grid View1. Line 136: Source Error: Line 134: string Um = ((Text Box)Grid View1.
You can see the C# code below will give the row number whatever you are editing by New Edit Index property.
So Grid View will put the appropriate row into the Edit Mode by assigning row number to its Edit Index property.

When I do an update, and get to the Grid View1_Row Updating, there is no value passed to "ID", and then when I go to the next row for "Company" I get the following error: Specified argument was out of the range of valid values. 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.Suppose if we are trying to hide primary key of our table, there is actually no need to hide. In the above Snippet you are seeing a label in Item Template that means whenever we are showing Grid View to the user Label will be visible to the user.In this example, this time I used my own database called Sample DB which has Customers Table and basically contains the following field columns: As you have noticed in STEP 2, we have added six Text Box and a Button in the web form in order for us to type the information there and Insert them to the database.
