I use the DataSource like below to fill a Combobox:

comboBox1.DataSource = dataSet1.Tables["Suppliers"];
comboBox1.DisplayMember = "ProductName";

When the user types any keyboard key i use the DROPDOWN property, like below, to show all combobox itens:

this.comboBox1.DroppedDown = true;

I use the content of the Combobox text to update my database.
I have a problem when the combobox lost focus, because the combobox text is cleaned. And its impossible to update the Database.
This only occurs when the user typing a new combobox item in a combobox text.

If i disable the Drop Down property my code works whell.

There is a way to make the DROP DOWN property works together the LOST FOCUS without clearing the new Combobox Text???

Thanks...

Dear Thomaz:
Could u explain more! I couldnt get u well.

Ok MELVIK;

The problem is the (DroppedDown) property.

When one combobox receives the focus I places the property (DroppedDown = true), but when this combobox loses the focus the text was typed in the ComboboxTextfield is cleaned.

It´s impossible to capture a new text typing because the droppedDown property cleaned the Combobox Text Field.

I thank its reply....
