Hello guys,

in my code combobox.findstringexact is returning -1 even when the combobox has that element. Please let me know whats the problem in my code. This silly problem is wasting my precious time. I know i am missing something here. Thanks

C#

comboBoxLanguage.DataSource = Enum.GetValues(typeof(ATXDataManager.Constants.Language));
comboBoxLanguage.SelectedIndex = comboBoxLanguage.FindStringExact(objAdminData.LANGUAGE.Value.ToString());

Your problem is probably the assumption that your text contains what you're looking for, if it did you wouldn't be getting -1 back, but we can't access your dropdown or your LANGUAGE.Value data. Look for differences in case, or for spaces, leading spaces, trailing spaces etc, just look closer at your data.

If you look at the definition of FindStrignExact[^] it returns -1 when the string is not found - so this is probably expected behavior.

In this case, the problem is likely to be that the combo box has not loaded yet: you are setting the DataSource immediate before trying to search for the string so the likelyhood is that the ComboBox has not loaded the data: it doesn't do it immediately, but defers the load until it is needed.

Why search the combobox collection at all, when you could just access the collection returned by the Enum.GetValues directly instead?

Thanks OriginalGriff for the response. The Combobox has the data loaded from the source. I checked by adding watch.
My situation is: the combobox data has to be linked to an enum. whenever i will get any value from my database, i need to show that exact value as the selected item in the combobox.
How to achieve this? :(

Well I may sound stupid. But the code is working now after restarting Visual Studio :)
:D
