问题 I have tried this method.. without luck.. <Style TargetType="{x:Type DataGridRow}"> <Style.Triggers> <Trigger Property="ItemsControl.AlternationIndex" Value="0"> <Setter Property="Foreground" Value="Red" /> </Trigger> </Style.Triggers> </Style> Is there a way to get the row Index? I have even tried <DataTrigger Binding="{Binding AlternationIndex}" Value="0"> <Setter Property="Foreground" Value="Green"></Setter> </DataTrigger> 回答1: Unless already done, you have to set the AlternationCount

问题 I am seeing a lot of examples on how to style Selected rows in DataGrid such as this one: How can I set the color of a selected row in DataGrid Can i just disabled selected row styling? i don't want to have to override every single thing that selected row changes.

问题 So I have a WPF DataGrid , which is bound to an ObservableCollection . The collection has validation on its members, through IDataErrorInfo . If I edit a cell in a way so as to be invalid, and then tab away from it before hitting enter, then come back and make it valid, the cell will stop showing invalid, however, the "!" at the head of the row will still be there, and the ToolTip will reference the previous, invalid value. 回答1: Not using Mode=TwoWay for DataGridTextColumns solves one version

问题 I have looked for and tried various solutions but so far none of them solve my problem. I am using the built-in DataGrid from WPF in Visual Studio 2010/.NET4 to display data from an XML document stored as an XDocument. My code all runs fine, and I have verified that the XDocument is present and correct. The DataGrid does not display any data, however. The XML looks like this (simplified for clarity): <data> <track> <id>211</id> <name>Track Name</name> <duration>156</duration> <artist_id>13<

问题 I'm using a DataGrid in a VS2010 WPF C# project. I have bound the DataGrid to an ObservableCollection. When you click on a column heading it sorts the data at that point in time. Question - How would I arrange such that the sorting in the DataGrid is dynamic, so that when data changes (within the ObservableCollection) the sorting keeps working. Notes: Binding approach is via DataGrid private ObservableCollection<SummaryItem> _summaryData = new ObservableCollection<SummaryItem>();

问题 i have a datagrid that contains 3 DataGridTemplateColumns that hold radioButtons. now i want to control the "isEnabled" property of the radioButtons from a click event of a button in my code behind: <DataGrid AutoGenerateColumns="False" Height="300" x:Name="dgEmps" RowEditEnding="gridEmps_RowEditEnding" CellEditEnding="gridEmps_CellEditEnding" FlowDirection="RightToLeft" SelectionChanged="gridEmps_SelectionChanged"> <DataGrid.Columns> <DataGridTemplateColumn Header="Shift Manager">

问题 I see a few options available for row selection, but 'No Selection' is not one of them. I've tried handling the SelectionChanged event by setting SelectedItem to null, but the row still seems selected. If there is no easy support for preventing this, would it be easy to just style the selected row the same as an unselected one? That way it could be selected, but the user has no visual indicator. 回答1: You have to call DataGrid.UnselectAll asynchronously with BeginInvoke to get it to work. I

问题 Good morning I have a Wpf datagrid that is displaying an observable collection of a custom type I group the data using a collection view source in XAML on two seperate properties, and I have styled the groups to display as expanders. For clarity, as there is a lot of data I feel I have to use margins and spacing otherwise things look very cluttered. My problem is that with two levels of hierarchical expanders the column data is now substantially offset from the column headers meaning that
