ComboBox.Text.Tostring() returned selected text and solved my problem

 String status = "The status of my combobox is " + comboBoxTest.Text

SelectedText property from MSDN

Gets or sets the text that is selected in the editable portion of a ComboBox.

while Text property from MSDN

Gets or sets the text associated with this control.

Combox1.SelectedItem retunrs you selected ListItem object not text value of selected item

its should be like :

ListItem li = Combox1.SelectedItem;

or 

Object selectedItem = comboBox1.SelectedItem;

    MessageBox.Show("Selected Item Text: " + selectedItem.ToString() );

From MSDN : http://msdn.microsoft.com/en-us/library/system.windows.forms.combobox.selecteditem.aspx

Combox1.SelectedText - Check Msdn for this : http://msdn.microsoft.com/en-us/library/system.windows.forms.combobox.selectedtext.aspx

FROM MSdn why its return empty string - if you retrieve the SelectedText value in a button Click event handler, the value will be an empty string. This is because the selection is automatically cleared when the input focus moves from the combo box to the button.

So altough, your question is not really gramatically clear, to get the calue of your selected item always use 

Combox1.SelectedValue

Why?

Because:

Combox1.SelectedItem

returns a string that represents the currently selected text in the combo box. If DropDownStyle is set to DropDownList, the return value is an empty string ("").

Use

Combox1.SelectedItem.Text // To get SelectedText
Combox1.SelectedItem.Value // To get SelectedValue

Instead of

Combox1.SelectedItem.ToString()
