Clear ComboBox selected text

I have a ComboBox control with the DropDownStyle properties set to DropDownList. Once there is an item selected, how can I clear the selection from the ComboBox without deleting any Items in it ?

I'd normally use something like that:

myComboBox.Text.Clear();

But I can't do that. Any idea how I could clear it ?

Try specifying the actual index of the item you want erase the text from and set its Text equal to "".

myComboBox[this.SelectedIndex].Text = "";

or

myComboBox.selectedIndex.Text = "";

I don't remember the exact syntax but it's something along those lines.

comboBox1.Text = " ";

This is the best and easiest way to set your comboBox back to default settings without erasing the contents of the comboBox.

Try this, if you populate your Combobox with objects:

Combobox.SelectedItem = null;

In c# if you make you comboBox configuration style DropDownList or DropDown then use both of them in this method to clear.

ComboBox1.SelectedIndex = -1;

The only way I could get it to work:

comboBox1.Text = "";

For some reason ionden's solution didn't work for me.
