I have set of items in ComboBox and non of them selected. I would like to show a string on combo \"Pl

Answer 1

I was hoping to find a solution to this as well. I see that this is an older post, but hoping my approach might simplify this problem for someone else.

I was using a combobox with a drop down style of DropDownList, but this should work with other styles. In my case I wanted the text to read "Select Source" and I wanted the other options to be "File" and "Folder"

comboBox1.Items.AddRange(new string[] {"Select Source", "File", "Folder" });
comboBox1.Text = "Select Source";

You can select the 0 index instead if you like. I then removed the "Select Source" item when the index is changed as it no longer matters if that text is visible.

comboBox1.SelectedIndexChanged += new EventHandler(comboBox1_IndexChanged);

private void comboBox1_IndexChanged(object sender, EventArgs e)
    {
        comboBox1.Items.Remove("Select Source");
        if (comboBox1.SelectedIndex != -1)
        {
            if (comboBox1.SelectedIndex == 0) // File
            {
                // Do things
            }
            else if (comboBox1.SelectedIndex == 1) // Folder
            {
                // Do things
            }
        }
    }

Thanks
