Error serializing value ‘System.Object[]’ of type ‘System.Object[].’

[Gavin Pollock]

Hi Guys,

We're currently upgrading our implementation of the Classic RadComboBox to the Ajax version, however after trying to assign the combobox SelectedIndex and Text properties with the below code we get the above error message.

cmbCats.SelectedIndex = cmbCats.FindItemIndexByValue(

value.NewsCategoryID.ToString());

 

cmbCats.Text = cmbCats.SelectedItem.Text;

We're using a List as the datasource object and if the above code is omitted the error is avoided, but obviously the correct item isn't selected.

I hope this is enough information to help you diagnose the problem.

Thanks,
Gavin.

Hi Gavin Pollock ,

The text of the selected Item will be automatically filled in in the input of the ComboBox.

Could you try removing the second line and test again?

In any case more information about the ComboBox definition and any related code manipulating it will help a lot.

Thank you in advance.

Best wishes,
