Kettic Grid View Control contains various properties for UI designer of the data grid to control the actions of end users of the grid.
For example, it is able to restrict user interaction and data modification including, rows editing and deleting, rows adding and positioning as well columns editing.
If you want to create a new row in code then you use the Binding Source like so: The user can then enter the field values via the UI and the row is committed to the underlying Data Table when they navigate away to another record. End Edit() End Using End Sub It shows me the new record but when i close the application , it doesn`t save.
If you use a Data Grid View then that's all you need, because it allows the user to add, edit and delete records. displaying one record at a time, then you need to add a bit more code to add or delete records. Read the last paragraph of my previous post and then ask yourself if that's what your code is doing. | MSDN Data Walkthroughs VBForums Database Development FAQ My Code Bank Submissions: VB | C# My Blog: Data Among Multiple Forms (3 parts) Beginner Tutorials: VB | C# | SQLPrivate Sub btn Save_Click(By Val sender As System.
What your click event does is: 1) Get data into gridview 2) Write data back to file immediately thereafter. That is where any change made to the datagridview gets comitted to the DB.
If you had your da be a global variable, (instead of local to that click), you might could just do the da.update(ds) in the click event.

Users of the Data Grid View control can implement the Value Changing and Value Changed events to create custom validation for their data gird in C# Windows Forms applications.
The C# code API for data editing, data inserting, as well as data deleting are included within the Grid View Control.
UI designer of the data grid can easily use the API to build the grid data editing behavior for columns and rows.
You need to learn t-sql (the "language" for interfacing with SQL). Look at this link: INSERTUPDATEand DELETEstatementsusing Especially the Modify Row() method. This bit of code will go out, get all the items from the database (the fill() method), and then immediately does an update (nothing gets changed).
What you need to do, is: 1) Get the data, and put it into gridview 2) Allow user to edit the gridview 3) Upon button click, write the data back out.
