将项目添加到ComboBox并选择相同的项目

Question

There is a Empty ComboBox to which I will be adding a Item and I want to select the same Item automatically. Currently I am using the code below and its working.

    twComboBox1.Items.Add(ComboBoxItem);
            if(twComboBox1.Items.Count > 0)
               twComboBox1.SelectedIndex = 0;

But I feel this method is quite naive. Is there a method to select the added item automatically. I tried searching for the same in google but couldn't find any satisfying answers.

Thanks in advance.

Answer 1

Another way of doing the same is

twComboBox1.Items.Add(ComboBoxItem);
twComboBox1.SelectedItem = ComboBoxItem;

OR if you are using ComboboxItem then you can use

twComboBox1.Items.Add(ComboBoxItem);
ComboBoxItem.IsSelected = true;

Answer 2

I don't really see the issue here, the best thing you can do is to remove the if statement containing the count as its not exactly necessary.

 twComboBox1.Items.Add(ComboBoxItem);
 twComboBox1.SelectedIndex = 0;

Its quick, its easy and it does what you want it to do.
