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
<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。
下一篇说以下环形图的制作。
