Then you can use textbox,why you need combobox if you want to read only it?

The use of the term readonly is confusing. If your aim is to prevent the user editing the text then use the DropDownStyle DropDownList.

See ComboBoxStyle[^]

I think you are talking about this.

You will be able to select items from drop down list,but you can't edit it.

C#

cmbTemplate.DropDownStyle = ComboBoxStyle.DropDownList;

You have to set the enabled property of the combobox to false.

C#

ComboBox1.Enabled=false;

We want to make a read Only combobox.

No,combobox will be hide if you use ComboBox1.Visible=false

ComboBox, the name itself describes that it is the combination of both DropDown and TextBox. So I don't think there would be any way to make it non-editable at all.

Or you may go for enforce not to write anything into box on keypress, by handling the keypress event to do nothing or to avoid type it in combobox.
Ex :-

C#

private void cmbTest_KeyPress(object sender, KeyPressEventArgs e)
{
    e.Handled = true;
}

For a combo box, this is a strange requirement, if you think about it. No wonder, there is no such feature if System.Windows.Forms. Anyway, please see this CodeProject article:
ComboBox with read only behavior[^].

I need to be able to lock a combobox as part of a trial key expiring and features being disabled which include changing or selecting other items in the combobox which is forced to the first item (as long as there are at least one item in the combobox)...so it isn't that strange of a requirement for what I'm doing, considering the user could add many items to the combobox during the trial. I just swap mine with a label that is populated with the current combobox selected item text. The user doesn't need to interact with the text in using my app, they just need to see what is selected.
