This example is part of a larger example available in the DataGridViewComboBoxColumn class overview topic.

In this example, the DisplayMember is set to the same value as ValueMember because no mapping is necessary. DisplayMember is set to the property name responsible for containing the user-viewable text. The following code example demonstrates how to use a DataGridViewComboBoxColumn to aid in data entry of the title column. The value of the CellTemplate property is null. Member this.DisplayMember : string with get, set Public Property DisplayMember As String Property Value StringĪ String that specifies the name of a property or column in the data source specified in the DataSource property. Member this.DisplayMember : string with get, set Then use x:Bind to bind the ComboBox.Gets or sets a string that specifies the property or column from which to retrieve strings for display in the combo boxes. Your view model should have a property SelectedBlockName. You typically bind this ComboBox.SelectedValue to the same view model (data context) that exposes the source collection, in your case the BlockDetails collection. Both properties serve the same purpose of exposing the currently selected item. You use ComboBox.SelectedValue instead of ComboBox.SelectedItem, if you are not interested of the actual data item, but a specific value of this item. You have ComboBox.DisplayMemberPath to select the property of this data type, which should be displayed by the ComboBox in the drop down.įinally you have ComboBox.SelectedValuePath to select a property of this data type to be the ComboBox.SelectedValue. You have an object or data type that is an item of the ComboBox. I think you either confused the SelectedValue property or missed to post some details. In my model the class is declared as follows, public class VmServiceMethodBlockDefinition : BindableBaseThreadSafe But the problem is it doesn't select/display the item. When I expand the combobox I can see the items inside it. I have a combobox which is bound to a property called 'BlockDetails' in the viewmodel.
