问题 At the moment my DataGrid shows the RowDetails when i click a row. But I want to show the RowDetails only on Double-click. Any ideas for solving this problem? Thank you! 回答1: e.g. <DataGrid RowDetailsVisibilityMode="Collapsed"> <DataGrid.RowStyle> <Style TargetType="{x:Type DataGridRow}"> <EventSetter Event="MouseDoubleClick" Handler="RowDoubleClick"/> </Style> </DataGrid.RowStyle> </DataGrid> private void RowDoubleClick(object sender, RoutedEventArgs e) { var row = (DataGridRow)sender; row

问题 I have a problem with a ScrollViewer that I use to scroll a user control that contains a data grid. Without the scroll viewer the columns fill the data grid as I want but when adding a scroll viewer the columns shrink to ~15px. I was able to simplify my layout and can still reproduce this behaviour. When binding the datagrid width to another control the columns have their normal with, but that has unsuprisingly the same effect as a fixed width on the datagrid. I guess I'm not the first one

问题 I'm trying to bind column visibility to that of another element like this: <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Window.Resources> <BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter" /> </Window.Resources> <StackPanel> <CheckBox x:Name="chkColumnVisible" Content="Show column" /> <DataGrid x:Name="MyDataGrid

问题 This is the code I have: private void btnSearch_Click(object sender, RoutedEventArgs e) { using (SqlConnection sc = new SqlConnection(sConn)) { sc.Open(); string SearchFor = txtSearch.Text; using (SqlDataAdapter adapter = new SqlDataAdapter()) { DataTable dt = new DataTable(); grdData.ItemsSource = dt.DefaultView.RowFilter = string.Concat("SELECT * FROM Student WHERE Forename LIKE '%", SearchFor, "%'"); } When I run the code I get: "Syntax error: Missing operand after 'Student' operator." I'm

问题 Basically, I have a DataGrid inside a DataGrid: <DataGrid ScrollViewer.CanContentScroll="True" ScrollViewer.HorizontalScrollBarVisibility="Auto" AutomationProperties.AutomationId="sCGridSelectedBasketItems" HeadersVisibility="Row" Height="{Binding ElementName=itemsgrid,Path=ActualHeight}" Grid.Row="1" RowDetailsVisibilityMode="Visible" CanUserAddRows="false" VerticalAlignment="Top" AutoGenerateColumns="False" SelectedItem="{Binding SelectedBasketItem}" ItemsSource="{Binding

问题 I want to change the selected row color dynamically in code behind. I'm using Visual Studio 2008. Can anyone help to do this? 回答1: Dim selectedItem As New Style(GetType(DataGridCell)) Dim triggerIsSelected As New Trigger() With {.[Property] = DataGridCell.IsSelectedProperty, .Value = True} triggerIsSelected.Setters.Add(New Setter(DataGridCell.BackgroundProperty, System.Windows.Media.Color.Red)) selectedItem.Triggers.Add(triggerIsSelected) Datagrid1.CellStyle = selectedItem 来源： https:/

问题 I have implemented IEditableObject for my ViewModel and the below controls are bound to it. Now when the first time I fire up the Window containing these controls, the BeginEdit() method runs and backs up the variables. My problem is this: When I start editing the DataGrid again the BeginEdit() method runs and saves the changes to my already backed up variables! This ruins the purpose of the BeginEdit() and CancelEdit() . Now if I choose to cancel the Window, I won't have the original data.

问题 I have a DataGrid that is bound to ObservableCollection. What I am wondering is: without resorting to looking at an item and retrieving the object type, can I somehow use the actual DataGrid object and the ItemSource to find the type of objects? So if I have the following: DataGrid dg = DataGridObject as DataGrid; Console.WriteLine("binding5=" + dg.ItemsSource.GetType()); output = System.Collections.ObjectModel.ObservableCollection`1[UserManagement.UserViewModel] Can I extract UserManagement
