ComboBox onSelectedIndexChanged Event

[Ather Ali Shaikh]

Hello,

I am working on three comboboxes Country, State and City.
When Country is filling with database its onSelectedIndexChanged event fires
for each binding, why? I fill State combobox for the selectedvalue of
country.
for the matter above of onSelectedIndexchanged, first time in SelectedValue
of Country combobox is "System.Data.DataRowView". Nest time it shows balnk
value and through and exception of zero based index.

I am very worry about it.

Please as soon as possible.

Regards,
Ather Ali Shaikh

Hi,

Could you post your data-binding code?

Make sure you are setting your ValueMember and DisplayMember prior to setting
the DataSource.
