问题 I am trying to give a new ItemsSource to a DataGridComboBoxColumn in a specific row in my program when the selection of an other DataGridComboBoxColumn in the same row is changed. The problem is that I am only able to change the ItemsSource of all rows at the same time. Is it possible to give a specific ItemsSource for a DataGridComboBoxColumn to only one row in a Datagrid ? This is the declaration of my DataGrid and my DataGridComboBoxColumn <DataGrid Name="DATAGRIDSEARCH"

问题 I am trying to use an enum in a Datagrid. Let me show you two ways that it can work. First, I create a ComboBox inside the DataGrid, the DataContext.MyOptions returns a list of Strings for all values of enum. <DataGridTemplateColumn Header="Enum1"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <ComboBox ItemsSource="{Binding DataContext.MyOptions, RelativeSource={RelativeSource AncestorType=Window}}" SelectedItem="{Binding Enum1, UpdateSourceTrigger=PropertyChanged, Converter=

问题 my first question, so please be gentle. I have tried for several days to figure it out. The closest I got was to programmatically access the content of the cell in the code behind. Is there a way to do it in the xaml? For instance, this doesn't work <Style x:Key="ComboBox" TargetType="DataGridCell"> <Setter Property="FontSize" Value="14"/> <Setter Property="FontWeight" Value="SemiBold"/> <Setter Property="HorizontalAlignment" Value="Center"/> <Setter Property="HorizontalContentAlignment"

These object are displayed in a DataGrid & a `SelectedObject I have a property PossibleParentObjects that returns a List of Objects based on the SelectedObject. I would like to have this property populate a ComboBox residing in a column of the DataGrid How can I do this? Here is what I have so far...

问题 I use ComboboxColumn in DataGrid which works fine. However there is a style issue: When cursor is not on the column, the ComboboxColumn looks like a textboxColumn . Once I click it, a tiny arrow on the right corner displays so it looks like a combobox. I want it to display like a combobox even when it is not clicked or focused. I feel it is ElementStyle , but not sure what to change to exactly. Does someone know how to do this? xmlns:dg="http://schemas.microsoft.com/wpf/2008/toolkit" <dg

问题 My DataGridComboBoxColumn does not show any data. It's empty.

问题 I have a DataGrid ComboBox Column that is bound to an Observable Collection of ComboBoxOption objects, these objects just contain 2 values, one that is the value displayed to the user and the other the required value. I am setting the bindings etc. during the AutoGenerating Columns event and this is all working fine. The problem I am having is trying to make the combo box display the required value only. This cannot be done in the XAML (Unless I can set up a column template in the XAML and

问题 I have a DataGridView with 4 columns, one of them being a drop-down (ComboBox) column. The values in this column must be distinct so once a given drop-down values is selected in a row, I'd like it to not be available in any of the drop-downs in other rows. If a given value is unselected it should show up in the drop-downs again. I found a few articles with similar examples (1,2,3); however, all of them seem to involve subscribing to an event and manually populating the ComboBox. Is there a

问题 Why is the ComboBox in that column only visible via double-click in the empty cell when the DataGrid is set to IsReadOnly = FALSE ??? <DataGridComboBoxColumn Width="*" IsReadOnly="False" Header="test" /> using a DataTemplateColumn works as always... whats wrong with that DataGridComboBoxColumn? works: <DataGridTemplateColumn Header="Schoolclass"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <ComboBox Background="Blue" /> </DataTemplate> </DataGridTemplateColumn.CellTemplate> <
