WPF: C# How to get selected value of Listbox?

Question

I am trying to fetch the selected value of the listbox. When I actually try LstGroup1.SelectedItem I get the value { BoothID = \"4\", BoothName = \"HP\" }

Answer 1

since you are using anonymous type to populate the listbox, so you have left with no option then an object type to cast the SelectedItem to. other approach may include Reflection to extract the field/property values.

but if you are using C# 4 or above you may leverage dynamic

    if (LstGroup1.SelectedIndex >= 0 && LstGroup2.SelectedIndex >= 0)
    {
        //use dynamic as type to cast your anonymous object to
        dynamic Booth = LstGroup1.SelectedItem as dynamic;
        //Few things to do 

        //you may use the above variable as
        string BoothID = Booth.BoothID;
        string BoothName = Booth.BoothName:

    }

this may solve your current issue, but I would suggest to create a class for the same for many reasons.
