I have a scenario where we do very specialized validations. In these validations we may get a pass or a fail on an update of the row. On failed validation, we will have to revert the modified data in the row. I was looking through the api and found the following which I think may work for me. What I am not understanding is on how I should this be used. Is the following command targeting a single selected row or is it target multiple selected rows. I just want to verify this before I go run off changing code.
this.ugDataGrid.PerformAction(Infragistics.Win.UltraWinGrid.UltraGridAction.UndoRow)
Thanks in advance.
Hello,
You are on the right path. This action targets the active row if he doesn't have any cells in EditMode. Here is a link from our online documentation describing the UltraGridAction enumerator: http://help.infragistics.com/Help/NetAdvantage/WinForms/2009.1/CLR2.0/html/Infragistics2.Win.UltraWinGrid.v9.1~Infragistics.Win.UltraWinGrid.UltraGridAction.html
You can use this with the ultraGrid1.UpdateData(); which saves any changes made in the grid to the data source it is using.
Hope this helps.
Sincerely,

In the same topic, can I change the active row without changing the selectedrows collection. I have a dialog where the actual assign to grid takes place and at the end, if row(s) does not comply with the validaiton, I have to perform undo. This action can be for a single or many rows in the selection. Should I be doing a loop, setting the active row of the grid (hoping the selection does not break) and then perform an undo.
You can't undo changes on anything but the grid's ActiveRow. Once the user leaves that row, the changes are committed to the grid's DataSource.
If you want to undo all changes, you might be able to undo the changes on the datasource - depending on what kind of data source you are using. DataSet and DataTable have methods for this. I think it's CancelChanges.
