Display a deleted DataRow in a (Infragistics.Ultra-) grid
Question
is it possible to display a DataRow from a DataTable which has the DataRowState.Deleted?
Scenario: The user can edit some kind of lookup-informations which are presented in the grid. Now he/she can delete, modify or insert multiple entries and finally store all his/her changes with one click to the database (assuming there is no primary-key-violation or some other problem).
Now i want to colorize the different rows according to their edit-status, but the deleted rows disappear immediatly.
Do you have any idea or another approach to solve this problem?
Solution
Edit: I realized that the Grid
you are using is not DataGridView
. For anyone who wants to do the same with DataGridView
, they can do the following:
Create a
DataView
:DataView myDataView = new DataView(myDataTable, String.Empty, // add a filter if you need one "SortByColumn", DataViewRowState.OriginalRows | DataViewRowState.Deleted); myDataGridView.DataSource = myDataView;
Handle
UserAddedRow
,UserDeletedRow
andCellValueChanged
Events:private void myDataGridView_UserAddedRow (object sender, DataGridViewRowEventArgs e) { e.Row.DefaultCellStyle.BackColor = ColorTranslator.FromHtml("#CCFF99"); } private void myDataGridView_UserDeletedRow (object sender, DataGridViewRowEventArgs e) { e.Row.DefaultCellStyle.BackColor = ColorTranslator.FromHtml("#FFCC99"); } private void myDataGridView_CellValueChanged (object sender, DataGridViewCellEventArgs e) { myDataGridView[e.ColumnIndex, e.RowIndex].DefaultCellStyle.BackColor = ColorTranslator.FromHtml("#FFFF99"); }
