Hi If you bind the dropdown onfly in the gridview event and set the selected value to the dropdown then value should be exists. This is clear that selectedvalue not exists in the drop down list. But you may bind correctly into the drop down list. If you use the update panel then you need to update it after bind with the dropdown control.
