i am using query base update in gridview but its not working and not showing any kind of and its not working plz help me string id = Grid View1.
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.
We’ll start with binding data to the Grid View, then build up functionality from there.

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.
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 problem come from UPDATE Statement [Error is New line constant I remove the plus sign and quotes after that it works properly] Thank u once again I m in a big problem in grdview i m trying to edit it throw command text ="edit" and insert vale on text box with save btnsave click..i m try if textbox insert vale are fill in gridview if btnsave click and if we wandt to edit it then on the same btnsave it save updated data use this for resolve updating errorsql Statement = "UPDATE Customers SET Company Name = @Company Name, Contact Name = @Contact Name, Contact Title = @Contact Title, Address = @Address, Country = @Country WHERE Customer ID = @Customer ID"; Thank you so much for this great tutorial! When i edit and click on update, it doesn't update anything. sql Statement = "UPDATE allmovies SET title = @title,company = @company,director = @director,editor = @editor WHERE id = @id"; hi vinz,my code for update command is public void update(string name, string email, int phone) and ROW UPDATING EVENT IS AS FOLLOWS string name = ((Text Box)Grid View1.
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.
The Grid View 'Grid View1' fired event Page Index Changing which wasn't handled.
