I don't have an answer yet, but maybe some info on the problem I am facing will help you.In my case, I am using the table styles to only show some of the columns. One of the columns I don't show is a SQL Server identity column, so SQL Server handles the input here. The other one, however, is a required column that I want to populate manually. I haven't yet figured out how to populate it but that is what is giving me the message: a required column that isn't populated. Is it possible that this is the problem you are having?Mark | Post Points: 5 viju.net India Since 1/31/2005 Posts 30 Reputation 285 Reply vijay k (viju.net) replied on 2/21/2005 11:16 PM rated by 0 users Hi mark,Thanks for ur reply, was waiting in vbcityWell, as ur using tablestyles , do u mean to add one more column in your datatable at run time or so ? not sure whether i am correct,If i am correct, then i think u can do it , see if this worksDim myColumn As New DataGridTextBoxColumn()with myColumn.MappingName = "Column Name".HeaderText = "Column Name".Width = 75.Nulltext="".Enabled = true.Allignment = HorizontalAlignment.Leftend with//now add column to ur tablestyle.

I have the following problem. I have a table and 4 stored procedures defined for the select, update, delete and insert data to the table. The table has 3 fields and one of them is record identifier with the ID char(15) that is generated by the SP during the insert. This field is PK for the table. I have created form with datagrid on it, added DataAdapter, generated Dataset, bound datagrid. DataGrid shows only two columns that are significant for the user (the ID is hidden). Run the app. The data is displayed on the grid and I can view, update and delete records. The problem comes when I want to insert new record. I receive error message in the form of MessageBox with the title "Error when committing the row to the original data store." and information "Column 'ID' does not allow nulls. Do you want to correct the value?". The message box comes before the RowChanging event, so I don't even have the possibility to modify the row. Can anybody help me with this issue? -- Regards Robert Top Error when committing the row to the original data store. by Jave » Fri, 07 Jun 2002 22:31:15 My guess is that the error is generated when the DataRowVersion.Proposed is rolled into DataRowVersion.Current of your newly entered row. Your Stored procedure will create the PK for the database, but I suspect that your code is not even getting to that point. Try putting a break point at the start of your Save code and follow the values of the two DataRowVersions of your row to see where the error occures. If you were using Integer Primary key (as opposed to Char (15), you can design your database to autoincrement and supply a new value for you. If the dataset knows that the PK is an autoincrement field, it will be more forgiving. These days, most database gurus are advising the use of such surrogate PKs. Also remember that a Char(15) field must contain 15 characters or the database will pad the value with spaces. This can be troublesome later on.
