Selected item not checked in UltraCombo
posted

I'm creating an UltraCombo and populating it with a DataTable. The table has two columns, the first is a boolean named "Selected" and the second is a string named "Name". Here's the code:

                        DataTable dropdowntable = ColumnValuesProvider.getTable((string)columnMeta["CUSTOM_CONFIG"]);
                        udd.DataSource = dropdowntable;
                        udd.ValueMember = dropdowntable.Columns[1].ColumnName;
                        udd.CheckedListSettings.CheckStateMember = dropdowntable.Columns[0].ColumnName;
                        udd.CheckedListSettings.EditorValueSource = Infragistics.Win.EditorWithComboValueSource.CheckedItems;
                        udd.CheckedListSettings.ItemCheckArea = ItemCheckArea.Item;
                        gridCol.EditorComponent = udd;

 

(The gridCol variable here is a column in an UltraGrid.)

For testing, the values in the table are { false, "abc", false, "def", true, "ghi" }.

I have two questions. First and most importantly, when I select the drop-down, the checkbox for the third row is unselected. How do I initialize the checkbox so it is checked/unchecked based on the value for the column's value?

Second, and perhaps related, I want the value of the "gridCol" to initially show a comma-separated list based on the rows whose Selected column is true. How can I do this?

Thanks....
