如何选择Windows Phone 8.1下拉所选项目

Question

In XAML

<ComboBox x:Name="CmbVendor" Style="{StaticResource ComboBoxStyle}" SelectedValue="{Binding vendor_name}"  >
    <ComboBox.ItemTemplate>
        <DataTemplate>
            <ComboBoxItem x:Name="text"  Content="{Binding vendor_name}"/>
        </DataTemplate>
   </ComboBox.ItemTemplate>
   <!--
   <ComboBoxItem Content="15 minutes" Tag="15"  />
   <ComboBoxItem Content="30 minutes" Tag="30"  />
   <ComboBoxItem Content="1 hour" Tag="60"  />
   <ComboBoxItem Content="1 day" Tag="1440"  />
   -->   
</ComboBox>

when I use static combo-box item I am getting data using the method

string Title = ((ComboBoxItem)CmbVendor.SelectedItem).Content.ToString();

but when I change to dynamic I am not getting selected item.

What is the solution?

Note In c# I called getdropdownvalue() in constructor

private async void getdropdownvalue()
{
    ........
    CmbVendor.ItemsSource = items;    
}

Answer 1

If the code you've added to populate the Combobox is something along the lines of:

List<VendorNames> vender_name = new List<VendorNames>();
vender_names .Add(new VendorNames() { Name = "NAMEHERE" });

Then to access the selected item:

 string Title = (CmbVendor.SelectedItem as VendorNames).Name.ToString()

This is just pseudo code hopefully to get you going along the lines.

I have the Modelclass like below.

public class Row
{
  public string vendor_id { get; set; }
  public string vendor_name { get; set; }
}

Then in your function

var value = CmbVendor.SelectedItem as Row;

and then

Dictionary<string, string> pairs = new Dictionary<string, string>();
pairs.Add("vendorID", value.vendor_id);
