Question

I have a combobox that I populate like this:

this.reqTypeInput.Items.Add(new RequestType("Label 1", "Value1"));
this.reqTypeInput.Items.Add(new RequestType("Label 2", "value2"));
this.reqTypeInput.Items.Add(new RequestType("Label 3", "value3"));

My RequestType class is:

class RequestType
{
    public string Text { get; set; }
    public string Value { get; set; }

    public RequestType(string text, string val)
    {
        Text = text;
        Value = val;
    }

    public override string ToString()
    {
        return Text;
    }
}

I have a value, “Value1” for example. How can I set the selectedItem of the combobox to the object {Label 1, Value1}?

I have tried:

this.reqTypeInput.SelectedIndex = this.reqTypeInput.Items.IndexOf("Value1");

If the request types do not change, you could store each RequestType object in a variable first, then set the SelectedItem property of the ComboBox to that variable.

For example:

RequestType type1 = New RequestType("Label 1", "Value 1");
RequestType type2 = New RequestType("Label 2", "Value 2");

reqTypeInput.Items.Add(type1);
reqTypeInput.Items.Add(type2);

Then, set it like this:

reqTypeInput.SelectedItem = type2;
