UWP 使用Telerik Grid控件

还是老规矩，看一下最终效果。

数据是从SQLite中读取，然后绑定到DataGrid中显示的。

先看一下XAML

开头引用—————— xmlns:grid="using:Telerik.UI.Xaml.Controls.Grid"

<grid:RadDataGrid Grid.Row="1" x:Name="radDataGrid"
                          Background="Transparent"
                          BorderThickness="1" GridLinesThickness="1"
                          UserEditMode="Inline" UserSortMode="Multiple"
                          SelectionUnit="Row" CanUserChooseColumns="True"
                          AutoGenerateColumns="False"
                          IsRightTapEnabled="True" RightTapped="radDataGrid_RightTapped"
                          IsHoldingEnabled="True" Holding="radDataGrid_Holding"
                          CurrentItemChanged="radDataGrid_CurrentItemChanged"
                          CurrentItemChanging="radDataGrid_CurrentItemChanging">

            <grid:RadDataGrid.Columns>
                <grid:DataGridTextColumn x:Name="columnId" x:Uid="columnId" Header="Id" IsVisible="False" PropertyName="Id"/>
                <grid:DataGridTextColumn x:Name="columnGuid" x:Uid="columnGuid" Header="Guid" IsVisible="False" PropertyName="Guid"/>
                <grid:DataGridTextColumn x:Name="columnFaceSetId" x:Uid="columnFaceSetId" Header="FaceSetId" IsVisible="False" PropertyName="FaceSetId"/>
                <grid:DataGridTextColumn x:Name="columnPersonId" x:Uid="columnPersonId" Header="PersonId" PropertyName="PersonId"/>
                <grid:DataGridTextColumn x:Name="columnName" x:Uid="columnName" Header="Name" PropertyName="Name"/>

                <grid:DataGridTemplateColumn x:Name="columnHead" x:Uid="columnHead" Header="Head">
                    <grid:DataGridTemplateColumn.CellContentTemplate>
                        <DataTemplate>
                            <Ellipse Width="50" Height="50" Margin="2">
                                <Ellipse.Fill>
                                    <ImageBrush ImageSource="{Binding Head}"/>
                                </Ellipse.Fill>
                            </Ellipse>
                        </DataTemplate>
                    </grid:DataGridTemplateColumn.CellContentTemplate>
                </grid:DataGridTemplateColumn>
                <grid:DataGridTextColumn x:Name="columnSignInItemName" x:Uid="columnSignInItemName" Header="SignInItemName" PropertyName="SignInItemName"/>
                <grid:DataGridNumericalColumn x:Name="columnSignInItemTimes" x:Uid="columnSignInItemTimes" Header="SignInItemTimes" PropertyName="SignInItemTimes"/>
                <grid:DataGridNumericalColumn x:Name="columnSignInAttendanceRate" x:Uid="columnSignInAttendanceRate" Header="SignInAttendanceRate" PropertyName="SignInAttendanceRate" CellContentFormat="{}{0:P0}"/>
                <grid:DataGridDateColumn x:Name="columnSignInDateTime" x:Uid="columnSignInDateTime" Header="SignInDateTime" PropertyName="SignInDateTime"/>
                <grid:DataGridTextColumn x:Name="columnSignInState" x:Uid="columnSignInState" Header="SignInState" PropertyName="SignInState"/>
            </grid:RadDataGrid.Columns>

            <!--<grid:RadDataGrid.SortDescriptors>
                <core:PropertySortDescriptor PropertyName="PersonId" SortOrder="Ascending" />
                <core:PropertySortDescriptor PropertyName="SignInItemName" SortOrder="Ascending" />
                <core:PropertySortDescriptor PropertyName="SignInItemTimes" SortOrder="Ascending" />
            </grid:RadDataGrid.SortDescriptors>-->
            
        </grid:RadDataGrid>

其中，我在 <grid:RadDataGrid.Resources 中定义了右键菜单，你自己根据需要删减。

属性	说明
Background	背景色
UserEditMode	用户编辑模式，Inline是行内编辑模式，External是弹出一个浮窗编辑
UserSortMode	用户排序模式，Multiple可以允许设置多个字段排序
SelectionUnit	选择单位，Row表示选择整行，Cell则是选择一个单元格
CanUserChooseColumns	是否允许用户选择列
AutoGenerateColumns	自动生成列，我设置的false，因为我数据库有很多字段，不想都显示在上面，所以需要自己定义。如果是true，则把所有字段都显示的

然后 grid:DataGridTemplateColumn 自定义模板。

后台C#读取数据库绑定的代码。

public ObservableCollection<SignInSummaryData> SampleItems { get; private set; } = new ObservableCollection<SignInSummaryData>();

代码绑定以下，然后加了一个排序，因为之前指定了 UserSortMode 为Multiple

        private async Task LoadDataAsync()
        {
            SampleItems.Clear();

            List<UserSignInInfo> list = await SQLiteHelper.GetAllUserSignInInfoAsync();
            //this.DataContext = SampleItems = new ObservableCollection<UserSignInInfo>(list);

            foreach (var item in list)
            {
                UserItemSQLite uis = await SQLiteHelper.GetUserAsync("Remark", item.PersonId);
                if (uis == null)
                    continue;

                BitmapImage thumbBi = new BitmapImage();
                if (uis.Head0 != null)
                {
                    StorageFolder storageFolder = ApplicationData.Current.TemporaryFolder;
                    StorageFile thumbFile = await storageFolder.CreateFileAsync("signInHeadthumbFile.jpg", CreationCollisionOption.ReplaceExisting);
                    await FileIO.WriteBytesAsync(thumbFile, uis.Head0);
                    StorageItemThumbnail sit = await thumbFile.GetThumbnailAsync(ThumbnailMode.DocumentsView, 400);
                    IRandomAccessStream ras = sit.AsStream().AsRandomAccessStream();

                    await thumbBi.SetSourceAsync(ras);
                }

                SignInSummaryData sid = new SignInSummaryData
                {
                    Id = item.Id,
                    Guid = uis.Guid,
                    FaceSetId = uis.FaceSetId,
                    PersonId = item.PersonId,
                    Name = uis.Name,

                    SignInItemName = item.SignInItemName,
                    SignInItemTimes = item.SignInItemTimes,
                    SignInAttendanceRate = item.SignInAttendanceRate,
                    SignInDateTime = Convert.ToDateTime(item.SignInDateTime),
                    SignInState = item.SignInState,

                    Head = thumbBi,
                    Head0 = uis.Head0,
                    Head1 = uis.Head1,
                    Head2 = uis.Head2,
                    Head3 = uis.Head3,
                    Head4 = uis.Head4,
                    Head5 = uis.Head5,
                    Head6 = uis.Head6,
                    Head7 = uis.Head7,
                    Head8 = uis.Head8,
                    Head9 = uis.Head9,

                    Area1 = uis.Area1,
                    Area2 = uis.Area2,
                    Area3 = uis.Area3,
                    Area4 = uis.Area4,
                    Area5 = uis.Area5,
                    Area6 = uis.Area6,
                    Area7 = uis.Area7,
                    Area8 = uis.Area8,

                    Gender = uis.Gender,
                    Mobile = uis.Mobile,
                    Email = uis.Email,
                    RemarkReal = uis.RemarkReal,

                };

                SampleItems.Add(sid);

                radDataGrid.ItemsSource = SampleItems;// = new ObservableCollection<SignInSummaryData>(list);
            }

            radDataGrid.SortDescriptors.Add(new PropertySortDescriptor() { PropertyName = "PersonId", SortOrder = SortOrder.Ascending });
            radDataGrid.SortDescriptors.Add(new PropertySortDescriptor() { PropertyName = "SignInItemName", SortOrder = SortOrder.Ascending });
            radDataGrid.SortDescriptors.Add(new PropertySortDescriptor() { PropertyName = "SignInItemTimes", SortOrder = SortOrder.Ascending });
        }

这样就可以实现开头的效果了。
