I have the following ComboBox with some bad data (fixing the data is on the list to do, but the system will launch with bad data.)
AllContacts is pulled from
<TelerikComboBox Data="AllContacts" TextField="FullName" ValueField="Id" TValue="int?" TItem="TblCompanyContact" Width="100%" Value="ContactId" ValueChanged="@( (int? c) => ChangeDropDownContact(c) )" Filterable="true" FilterOperator="StringFilterOperator.Contains"> </TelerikComboBox>@code{
List<TblCompanyContact> AllContacts; int? ContactId; protected void ChangeDropDownContact(int? c) { if (c != 0 && c != null) { //more code will go here when c is not null ContactId = c; } else { ContactId = null; } }
