problem with combobox default display text

I want to create a combobox with its displaymember populated from a
datatable. But once I get it run, the default display member in the
combobox is always the first row of the displaymember list. even if I
abitrarily set the combobox text to empty string, the value retrieved
from the combobox text is still the first row value from the list. How
can I set, when I display this combobox, the default display text to be
empty, instead of the first row of the list? Thanks a lot.

I am using a class that inherits from the DataGridTextBoxColumn. It adds a combo box into the column where it displays a selection of choices. The problem I have is that when this comboBox loses focus I lose the selected text. And this next line isn't setting the text in the cell. // code within the custom DataGridComboBoxColumn class this.TextBox.Text = this.ComboBox.SelectedItem.ToString();

Using .Net CF, i have created a 2 dimension ArrayList, and "binded" this list to a ComboBox control using the "DataSource" property. I have set the DisplaySource and ValueMember properties as well. The control populates well, both the display values, and selected values. However, when i try to "set" the SelectedValue or SelectedIndex properties, nothing happens.... The default blank value in the ComboBox is always selected. My code is: ...

Hello, For my new Windows application, all I want is to create an initial form to demo to the user to show them how it looks like with some data on it. So I figure the fastest way is to create some comboBox-es to show some data on them manually entered in the code without connecting to the database yet. It should be simple but somehow I can't make it work. First, I drag a comboBox from the ToolBox to the form. Then,

Hi Everyone, I am at my wit's end here. I have a combobox (combyQueryTitle) that I need to use in order to select a query for my database project. Therefore, I am using the comboQueryTitle_SelectedIndexChanged handler to, when a new selection is made, update the query and refresh the display. The only problem is that the program seems to inexplicably start with the ..selectedindex property at -1! This makes no sense to me. ...
