Question

I have 2 combobox here. cb1 and cb2.
I need to set like, when cb1.SelectedText = “aa”, the list of items in cb2 will be “1,2,3”
when cb1.SelectedText = “bb”, the list of items in cb2 will be “5,6,7”;
how can i do that?

Answer 1

You need to wire up the SelectedIndexChanged Event for cb1 –

cb1.SelectedIndexChanged += new EventHandler(cb1_SelectedIndexChanged);

Handle Event & populate cb2 based on the selected text in cb1 as follows –

void cb1_SelectedIndexChanged(object sender, EventArgs e)
    {
        // Get Selected Text of cb1
        string selectedText = cb1.SelectedText;

        // Populate cb2 based on the selectedText 
    }

Hope it helps…
