Save datagrid back to dataset.

pdamson80 asked
Last Modified: 2010-08-05
Hi, I have a windows form with a combo box and a datagrid. When I load the form, the datasets are generated and for each item in the combo box, there is a seperate dataset for each item in the combo box. The top value in the combo box is selected programatically and the coresponding dataset is displayed in the datagrid. Each time the user selects a different value in the combo box, the correct dataset is displayed in the datagrid. This all works fine.

I allow the user to edit one of the columns in the datagrid.  If the user selects a different value in the combo box, I want to save the new values into the original dataset so when the original value in the combo box is selected the changes are not lost.

Can anyone help me with this?

Thank you

I have tried that, I put it in the combo box's click event, it doesn't update it.

Are you reloading the datasets from the database in the Combo box's selected index changed event?

One more issue to be kept in mind is, the changes made to a row in the datagrid is committed to the underlying datasource only when the cursor moves to the next "ROW"...


I am only getting the data from the database once. I am not adding rows to the datagrid, I am changing data in a column

If you do the following , your problem will be solved.

1) in Constructor of your Forms After All DataSet Filled for the first time , write the following code for ALL table in ALL DataSet.

Now suppose you have UpdateTables function to reflect the DataGrid Changes to DataSource :

 Call AcceptChanges Method just like in Constructor :



Note that you should Call Update Method on your DataAdapters Before calling AcceptChanges Method.

can you post some code?
