People date multiple people without really telling what’s going on and then all of a sudden things become official — “he’s my boyfriend now.” It is not acceptable for women to ask men out (believe me, it never works out even if he said yes on that first date). I want to be able to pay my way, not feel pressured, and hell, if I like that man, I ask him out.

Next, we'll see how to create an editable Grid View from an Object Data Source.

As you may have guessed, when creating an editable Grid View whose data comes from an Object Data Source, the underlying data access layer class must provide an appropriate Update method.

The problem is, that when I press update with a breakpoint on Sql Data Source. This prevents the grid from updating for some reason. Hi there, When you call Data Bind in Page_Load, you tell your controls to data bind. NET 2.0 Instant Results and Beginning Dreamweaver MX / MX 2004My advice would be to steer clear of the sqldatasource and use a 3-tiered approach to retrieving, displaying and collecting data.

I don't know why yet, or how to bind the page..if I remove Data Bind from Page_Load, updating is successful. This means fresh data is retrieved from the database as soon as the page loads. Is Post Back) This way, Data Bind is only called when the page initially loads and leaves your edits alone on postback. Get the data from your database using a sqldatareader and store it in a custom collection by defining your own custom object.

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 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.

When the end user clicks on an Edit button that row becomes editable, causing the Edit button to change to Update and Cancel buttons and the other columns to become Text Boxes.

The end user can then update one or more column values and click Update to save their changes. Our first demo will look at how to create an editable Grid View whose data comes from a Sql Data Source.

For demonstration I have created a database (named Database.mdf) in which we have a table named tbl_Employee.

Contol[0])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.

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.

The Grid View allows editing on a row-by-row basis.

An editable Grid View contains an additional column with an Edit button in each row.
