RadComboBox.PerformDataBinding exception handling

[Jeroen]

I've pasted a code snippet from within RadComboBox.PerformDataBinding. Is there any reason that the ID of the dropdown is not put in the exception? This seems like a very easy code change that would help many people tremendously in debugging binding issues when they have multiple dropdowns.

I believe an OOTB ASP .NET dropdown box will also show the ID on a binding exception.

 

RadComboBoxItem selectedItem = FindItemByValue(cachedSelectedValue);

    if (selectedItem == null)

{

    throw new ArgumentOutOfRangeException("value", "Selection out of range");

}

It doesn't look like this suggestion got any traction. I'll second this feature request and add two more.

In addition to the exception message showing the control ID, it should show the value (cachedSelectedValue). 

Also, it would good if the control raised an event that we could choose to handle when the selected value does not exist in the list items.

Hello Joel,

I have converted the feature request to a public item, in order to track its process and vote for it here. As for the other suggestion, related with the cachedSelectedValue and the raise of the event - you could comment the feature request, providing more details on the information which the exception should provide.
