datagridcomboboxcolumn

问题 I've looked at the answers to various questions, but haven't managed to map the content in the answers to the problem I'm attempting to solve. I've reduced it down to the following code (representative of the outcome I'm trying to achieve), and basically want to be able to render the Person.TitleId as its corresponding Title.TitleText when the row isn't being edited, and have the drop-down bound correctly so that it displays the TitleText s in the drop-down and writes the associated TitleId

问题 I have a Winforms application which has a DataGridView . The DataGridView is not bound to a datasource. I'm reading a text file and according to each line in the file, I'm placing the values of each row to the datagrid. I have a column in my grid that is a ComboBoxColumn .

Then in C#, I create a DataGridTextColumn and a DataGridComboBoxColumn and binded these to the properties of the objects inside the ObservableCollection. I can bind the DataGridComboBoxColumn to a simple Collection but what I want to do is bind it to a collection of collections of strings so that for each row the ComboBox inside the DataGrid has a

问题 In My DatagridView ,I Have Two Columns, ComboxboxColumn and TextboxColumn . I want to change the value of textbox when combobox selected index changes (in general combobox it has selected index change event but datagridviewComboBox does not have it) 回答1: Give these two simple methods a go (the '1' in the top method is the index of the combobox column) The line that you would make you modifications to would be the setter line cel.Value = , as you may change it to whatever you like. private
