Here is the sample. I am using xamcombofield. I need to update books field based on branch selection.

Initially books combo box field should be disabled. Based on branch selection books field should be enabled and populate the results based on branch selection.

Hello Yugandhar,

In order to achieve this the SelectionChanged event of the ComboBox needs to be handled. Then a custom item filter for the XamMultiColumnComboEditor needs to set based on what is selected inside the ComboBox, FilterMode can be set (either on the main column or on all columns) as well as the CustomItemFilter comparison condition.

To learn more about item filtering inside XamMultiColumnComboEditor please visit the link below, which describes the configuration of custom item filters in more details as well as providing sample code, which demonstrates how custom item filters can be configured.
