Updating dataset with gridview

open visual studio – In above screen we can see, there are five column in User Mst Table in sql.The first column is ID which is identification of user, so it must be unique.Well when I run my applications now I don't get any real error, but the data base is NOT being updated Please have a look at my code below and tell me what to do in order to be able to update my data base with a changed Data Set. Page { private Data Set my Data Set; private Data Table my Data Table; private EBBWS. Hi Wencui Qian Thank you for your willingness to help me I tried to put the line: my Sql Command Builder.The code behind in my cs file looks like this: public partial class Profile Info : System. EBBWeb Service my WS; string db First Name, db Last Name; string session User ID = "1"; protected void Page_Load(object sender, Event Args e) protected void save Button_Click(object sender, Event Args e) But it doesn't work I get this Error: "Data Table already belongs to this Data Set." I can understand the error, because after all what I am trying to do is to change data which already exists in the dataset. Get Update Command(); Into my DAL code, but I still get the same error: "Data Table already belongs to this Data Set." Obviously I am doing something wrong when I try to update the Data Set with the updated Data Table, my code looks like this: Hi, If your problem is with saving, why dont you loop through your datatable records and save each single row seperately. Accept Changes(); If you call this method before updating, all the row states will be updated.Data Layer – Finish above dataset wizard with bind select, insert, update and delete stored procedure with it. Page – When we click Edit button we have screen like below with Update and Cancel Button, and all the value of that row are in textbox so we can modify and click update button to update record in database.After binding all stored procedure we have connection string in web.config file. Web Controls; using Business Layer; public partial class _Default : System. I am trying to get this to work in a simple example.

In previous post we discussed how to create 3 – tier architecture application using c#.

I didn't do any validation for gridview fields in this code.

But this code work perfectly according to the functionality. create table Customer( s_no int IDENTITY(1,1) primary key, First_name varchar(20), Last_name varchar(20), Address varchar(20)) /* identity used to generate number automatically Syntax: IDENTITY( seed, increment) After that include one row data with sql server, if not when run the code without data in table it wont show anything in browser.

Also, can you tell me the best book to buy that fully explains the Data Grid View control? Interesting that not a lot of people are using the datagridview object yet. In my example (from an app I am currently working on) I add data to the new row to the datagridview. Data Grid View Cell Event Args) Handles dgr Mod Sub Detail. This was mentioned in another topic in this group, and in a book "Programming VB. I don't understand the whole thing, but I'm going to keep track of your thoughts to see if I understand them better later on.

The trick is to add the row to the underlying data Table which is the datasource of the datagridview: Private Sub dgr Mod Sub Detail_Cell End Edit(By Val sender As Object, By Val e As System.
