在资源字典头多项目组合框？ [英] Multiple item combo box with headers in resource dictionary?
本文介绍了在资源字典头多项目组合框？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我按照
I have followed the accepted answer of this question to define a multi-column combobox with headers.
这不是为我工作，所以我做了一些改动它，现在它的作品。下面是创建与头一个多列组合框的XAML。
It was not working for me, so I made some changes to it and now it works. Here is the xaml to create a multi-column comboBox with headers.
<Page.DataContext>
<vm:ItemsViewModel />
</Page.DataContext>
<Page.Resources>
<CollectionViewSource x:Key="UnitsCollection" Source="{Binding Units}" />
</Page.Resources>
<ComboBox Grid.Row="0" Grid.Column="4" Grid.ColumnSpan="2" Grid.IsSharedSizeScope="True"
x:Name="cbUnits" ItemsSource="{DynamicResource Items}" IsEditable="True" TextSearch.TextPath="Symbol"
SelectedValue="{Binding SelectedUnit}" SelectedValuePath="UnitID">
<ComboBox.Resources>
<CompositeCollection x:Key="Items">
<ComboBoxItem IsEnabled="False">
<Grid TextElement.FontWeight="Bold">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="A" />
<ColumnDefinition Width="50" />
<ColumnDefinition SharedSizeGroup="B" />
</Grid.ColumnDefinitions>
<Grid.Children>
<TextBlock Grid.Column="0" Text="Name" />
<TextBlock Grid.Column="2" Text="Symbol" />
</Grid.Children>
</Grid>
</ComboBoxItem>
<Separator />
<CollectionContainer Collection="{Binding Source={StaticResource UnitsCollection}}" />
</CompositeCollection>
<DataTemplate DataType="{x:Type models:Unit}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="A" />
<ColumnDefinition Width="50" />
<ColumnDefinition SharedSizeGroup="B" />
</Grid.ColumnDefinitions>
<Grid.Children>
<TextBlock Grid.Column="0" Text="{Binding Name}" />
<TextBlock Grid.Column="2" Text="{Binding Symbol}" />
</Grid.Children>
</Grid>
</DataTemplate>
</ComboBox.Resources>
</ComboBox>
</Page>
现在，我想定义的<部分; ComboBox.Resources> ; 在资源字典，这样我就不用一次又一次地写。我也希望两个功能添加到资源字典：
Now, I would like to define the section between <ComboBox.Resources> in a resource dictionary, so that I would not have to write it again and again. I also want to add two more functionalities to the resource dictionary:
-
绑定列名和列值以某种方式东西（我不知道），因此，任何两列的组合框可以使用这个资源字典。
Bind the Column-names and the Column-values somehow to something(I don't know), so that any two column combobox can use this resource dictionary.
如果可能，我想补充一些逻辑资源字典使得相同资源字典可以用于与任意数量的列任何组合框
If possible I would like to add some logic in resource dictionary so that the same resource dictionary can be used for any combobox with any number of columns.
我认为有人能指引我正确的方向，如果有人做了在过去的这件事情，然后我可能会得到一些帮助，了解，这是在问这个问题的另一种内涵。
I think somebody could guide me to the right direction and if someone has done this thing in past then I may get some help for that, which is another intension of asking this question.
如果我上述quesitons不是只使用XAML解决，那么我也很愿意接受的解决方案。
If my above quesitons are not solved using only xaml, then also I would happily accept the solution.
推荐答案
尝试，这可能是这将帮助你。我刚才编辑的组合框style.Please separatly运行这段代码。
Try this may be this will help you.I have just edited combobox style.Please run this code separatly.

您可以写在资源此组合框的DataTemplate also..so可以使用下拉框datatempalate多个再寄一次。没有写在资源
You can write this combobox datatemplate in resources also..so you can use combobox datatempalate multiple time.I haven't written in resource.
<Grid>
<ComboBox x:Name="Combobox" Margin="50,0,0,0" IsEditable="True" HorizontalAlignment="Left" IsTextSearchEnabled="True" TextSearch.TextPath="symbol" ItemsSource="{Binding cmb }" Style="{StaticResource 2_Column_Cmb}" Height="30" ItemContainerStyle="{StaticResource Column_CmbItem}" Width="200" Tag="Item1">

<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding name}" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Column="0" FontSize="15" TextTrimming="CharacterEllipsis" Foreground="Black" />
<TextBlock Text="{Binding symbol}" Grid.Column="1" VerticalAlignment="Center" HorizontalAlignment="Center" FontSize="20" Foreground="Black"/>
</Grid>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
<ComboBox x:Name="Combobox1" Margin="0,0,50,0" HorizontalAlignment="Right" IsEditable="True" IsTextSearchEnabled="True" TextSearch.TextPath="symbol" ItemsSource="{Binding cmb }" Style="{StaticResource 3_Column_Cmb}" Height="30" ItemContainerStyle="{StaticResource Column_CmbItem}" Width="200" Tag="Item1">
<ComboBox.ItemTemplate>
<DataTemplate>
<Grid Background="Transparent" SnapsToDevicePixels="True">
<Grid.ColumnDefinitions>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding index}" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Column="0" FontSize="15" TextTrimming="CharacterEllipsis" Foreground="Black" />
<TextBlock Text="{Binding name}" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Column="1" FontSize="15" TextTrimming="CharacterEllipsis" Foreground="Black" />
<TextBlock Text="{Binding symbol}" Grid.Column="2" VerticalAlignment="Center" HorizontalAlignment="Center" FontSize="20" Foreground="Black"/>
</Grid>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
</Grid>
C＃代码
InitializeComponent();
List<ComboboxData> cmb = new List<ComboboxData>();
cmb.Add(new ComboboxData("1.","Tidle", "~"));
cmb.Add(new ComboboxData("2.", "Exclamation", "!"));
cmb.Add(new ComboboxData("3.", "Ampersat", "@"));
cmb.Add(new ComboboxData("4.","Ampersand", "&"));
cmb.Add(new ComboboxData("5.","Dollar", "$"));
Combobox.ItemsSource = cmb;
Combobox1.ItemsSource = cmb;
public class ComboboxData
{
public string index { get; set; }
public string name { get; set; }
public string symbol { get; set; }
public ComboboxData(string index,string name,string symbol)
{
this.index = index;
this.name = name;
this.symbol = symbol;
}
}
同样可以为4列，5列编辑模板。另
similarly you can edit template for 4 column, 5 column also.
