I have a RadGrid with filters. The FilterType is "HeaderContext".
I have restricted the filter options contained in the drop down list according to the field type.
For example, for a numeric field, I use options "GreaterThan", "LessThan" etc. For a string, I use options "Contains", "StartsWith" etc.
To achieve this, I use the following:
<Scrolling AllowScroll="false" />
<ClientEvents OnFilterMenuShowing="FilterMenuShowing" />
<FilterMenu EnableImageSprites="False" OnClientShowing="MenuShowing" />
However, these events are not invoked when the value RadGrid's FilterType is "HeaderContext".
This means that for each data type, the filter option drop down list contains all options, many of which are irrelavant.
Please can you offer some assistance that will enable me to restrict the filter options contained in the DropDownList where the FilterType of the RadGrid is "HeaderContext".
