【问题描述】:
在 AutoSuggestBox 中选择项目而不是它绑定到属性的属性值。
这是我的 xaml。
<AutoSuggestBox x:Name="txtSearchBox" ItemsSource="{Binding}"
PlaceholderText="Search in Distributor" Style="{StaticResource AutoSuggestBoxStyle1}"
Margin="10,25,10,0" DisplayMemberPath="{Binding entityName}" TextMemberPath="{Binding entityName}"
BorderBrush="#000000" BorderThickness="2" TextChanged="txtSearchBox_TextChanged"
SuggestionChosen="txtSearchBox_SuggestionChosen">
<AutoSuggestBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding entityName}"
Tag="{Binding entityId}"/>
</DataTemplate>
</AutoSuggestBox.ItemTemplate>
</AutoSuggestBox>
这是背后的代码
private void txtSearchBox_TextChanged(AutoSuggestBox sender, AutoSuggestBoxTextChangedEventArgs args)
{
if (args.Reason == AutoSuggestionBoxTextChangeReason.UserInput)
{
List<Master_User_Hierarchy_VM> lstUserHierarchy = new List<Master_User_Hierarchy_VM>();
txtSearchBox.ItemsSource = null;
foreach (Master_User_Hierarchy_VM obj in lstMaster_UserHierarchy_VM)
{
if (sender.Text != "")
{
if (obj.entityName.Contains(sender.Text))
{
lstUserHierarchy.Add(obj);
}
}
}
txtSearchBox.ItemsSource = lstUserHierarchy;
}
else if (args.Reason == AutoSuggestionBoxTextChangeReason.SuggestionChosen)
{
//txtSearchBox.Text = txtSearchBox.Items[0].ToString();
}
}
private void txtSearchBox_SuggestionChosen(AutoSuggestBox sender, AutoSuggestBoxSuggestionChosenEventArgs args)
{
txtSearchBox.Text = ((Master_User_Hierarchy_VM)args.SelectedItem).entityName;
}
这是我输入字符的时候
当我单击此列表中的项目时
我再次在建议框中获得了选定的项目。当我单击它时,我得到属性名称而不是值
