Unbound mode is suitable for displaying relatively small amounts of data that you manage programmatically.I have done this kind of stuffs with vb6, has not done it with C#. the better idea is create a new function in datagridform, then shift(cut & paste) the code which you use to fill datagridview in a new function(means refactor the code to function). Now when you close the add form call that function. I want to know how to insert/update/delete in a Multiple tables in a single datagridview. thanks thendral HI Rahim, My Name is Raman ,as per the above comments , I understand you are very good at I am new to win app, but good SQL server, Can you tell me , I Can Solve the below querdy. Im writing code like this connection String = “Data Source=;database=Northwind; User ID=sa; Password=sa”; but Sql server2005 error shows like : SQL Server doesn’t allow remote connections. but i want to learn that how we doing this through DLL. I have single button “SAVE” which save the data in the database. how can i set , update or insert or delete operation on one “SAVE” button. You could do it in SQL Server directly: you could try the following: - Open the CSV file with a Stream Reader - Read it line by line with Stream Reader.

Read Line() - Split the line into an Array of strings depending on the delimiter (with String.

In case you are adding row by row, then clear the rows of datagridview first in the function How we can access the entry’s in another system using LAN while running software in both systems. i want to add, delete, update in my C# forms through DLL… I have 5 tables and one datagridview , which display the information from 5 different tables, now user is allowed add/update/delete opration in the grid with new information.

How to write the connection string to that in windows application(C#). adding , deleting , updating textboxes is very simple if we write codes on buttons. user can add or update or delete the datagridview row.

Virtual mode gives you a higher degree of control by allowing you to wait until a cell is actually being displayed to provide the value it will contain.

The following C# source code illustrate how to connect a Data Grid View to a database and new/update or delete the database values from Data Grid View.

Add a Data Grid View control and two Buttons on a Form. This will be something like…(please check out code syntax) Integer i = Data Grid View1. Dynamic SQL generation for the Update Command is not supported against a Select Command that does not return any key column information………. my first form is datagridview …side buttons is.,edit, delete,and close…now i want add some details then click add button then open another form….insert the data from add form…add form close after inserted data…..i want automatic refresh the form1…… When you click add button , close the datagrid form, open up the add data form.
