WebDropDown EnableCustomValues AutoPostBack
posted

Hi,

I have 3 WebDropDowns on my page in an update panel all with EnableCustomValues=false. After the user selects an item from the first dropdown a postback occurs and the next dropdown is populated with relevant data.  This works fine if the user selects an item using the dropdown button, the problem I am having though is that if the user starts to type in the dropdown a postback occurs before something has been selected.  I have tried different settings using the AutoPostBackFlags but don't seem to be able to stop this postback happening before a complete value has been selected.  Can you please advise on how I might achieve this?

Many Thanks
