Hi AtulKatare,
What do you want to Quick Watch? Do you mean something like this:
string[] str = { "12345", "23456", "34567" };
textBox1.AutoCompleteCustomSource.AddRange(str);
textBox1.AutoCompleteSource = AutoCompleteSource.CustomSource;
textBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
Best regards,
Ling Wang
