问题描述
我有以下数据集,其“ PART”数据表列绑定为PropertyGroupDescription。我还想绑定“ DESCRIPTION”列,但不要将其绑定到PropertyGroupDescription,因为这会影响分组。
我现在得到的是:
ID | NAME
PART: 1
1 | AAA
2 | BBB
PART: 2
3 | CCC
PART: 3
4 | DDD
5 | EEE
我想要得到什么:
ID | NAME
PART: 1,DESCRIPTION: ATLANTA
1 | AAA
2 | BBB
PART: 2,DESCRIPTION: NEW YORK
3 | CCC
PART: 3,DESCRIPTION: BOSTON
4 | DDD
5 | EEE
由于具有相同部件号的所有行共享相同的描述。
当前代码:
CS:
public DataTable DataGridParts;
readonly CollectionViewSource mycollection;
public void FillDataGridParts()
{
sqlCommand cmd = new sqlCommand
{
CommandType = CommandType.Text,CommandText = "SELECT * FROM [PARTS] WHERE [STA_SID] = @StaSid AND [OWNER] LIKE @Search COLLATE latin1_general_CI_AI ORDER BY LEN ([PART]),[PART] ASC,[DESCRIPTION] DESC,[SHARE] DESC",Connection = sqlConnection.con
};
cmd.Parameters.AddWithValue("@StaSid",GlobalStrings.building_sta_sid);
cmd.Parameters.AddWithValue("@Search",'%' + textBox_search_part.Text + '%');
Mouse.OverrideCursor = Cursors.Wait;
sqlDataAdapter da = new sqlDataAdapter(cmd);
DataGridParts.Clear();
da.Fill(DataGridParts);
datagrid_parts.ItemsSource = DataGridParts.defaultview;
mycollection.GroupDescriptions.Clear();
mycollection.GroupDescriptions.Add(new PropertyGroupDescription("PART"));
datagrid_parts.ItemsSource = mycollection.View;
Mouse.OverrideCursor = null;;
}
XAML:
<DataGrid.GroupStyle>
<GroupStyle>
<GroupStyle.ContainerStyle>
<Style targettype="{x:Type GroupItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate targettype="{x:Type GroupItem}">
<StackPanel>
<TextBlock Height="20" Padding="0,3,0" FontWeight="SemiBold" Background="#e4e4e4">
<TextBlock.Text>
<MultiBinding StringFormat="{}PART: {0},DESCRIPTION: {1}">
<Binding Path="Name" />
<Binding Path="???" /> //NO IDEA HOW TO BIND HERE
</MultiBinding>
</TextBlock.Text>
</TextBlock>
<ItemsPresenter/>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</GroupStyle.ContainerStyle>
</GroupStyle>
</DataGrid.GroupStyle>
解决方法
<Binding Path="Items[0].DESCRIPTION" />
应该在假定具有相同部件的所有行共享相同的描述并且DataTable
中有一个名为“ DESCRIPTION”的列的情况下工作。
