Set selected index combobox c#
I am trying to set selected item of comboBox on click event of DataGrid, but I could not. I have googled and tried different ways but without success. For me SelectedIndex is working, but I could not find the index of items in ComboBox, so I could not select the item. Not working code: This property indicates the zero-based index of the currently selected item in the combo box list. Setting a new index raises the SelectedIndexChanged event. SelectedIndex, SelectedValue, and FormattingEnabled are related as follows: If FormattingEnabled is false, SelectedIndex will not be set to -1 when SelectedValue is blank. > I set the selected item of a combobox like this: > > myCombo.SelectedItem = 3; > > But after that the ComboBox displays only the first entry of the list. > When I add the line > > myCombo.DroppedDown = true; > > before, and then step trough the code, I can see the list of the combo > dropping down, then the index (in this case 3) gets selected. After Is it possible to set the selectedIndex of a combobox based on its value, without having to iterate through the datasource? I set the datasource like this: caseDBTableAdapters.usersTableAdapter If the object is found in the list, it is displayed in the edit portion of the ComboBox and the SelectedIndex property is set to the corresponding index.

The approach of setting the row[Column, Index].Value seems to result in the full type Name being displayed in the ComboBox instead of the DisplayMember (which I am explicitly setting). Additionally, since the value has been explicitly set that cell becomes read only in effect.
