Problem clearing the text in a combobox

[Stephen Robertson]

using vb.net:

I have some comboboxes that are bound:

..DataSource = dstPerson.Tables("postype")
..DisplayMember = "type"
..ValueMember = "postype_id"
..DataBindings.Add("SelectedValue", dstPerson.Tables("person"),
"postype_id")

The combos DropDownStyles are set to dropdown so the user can blank
out a selection.

When a combo's text is cleared and a save button is clicked
(.AcceptChanges is called on the dataset), the text returns.
Although, if I load the data again, it is blank.

Any ideas on how to clear the text?

Hi Stephen,

Do you mean How to clear the text of current selected item using ComboBox?

If you mean, selecting a certain item, clear the text area of the ComboBox
then save, to update the display text of selected item to empty. You need
bind the Text property to
the "type" column.

If you just mean clear the selection of the ComboBox, you may try adding
comboBox1.SelectedBox = -1;
comboBox1.SelectedBox = -1;
after AcceptChanges();

Does this resolve your problem?
If you still have problem on this issue, please feel free to let me know.
Thanks!
