Save/Load FilterDescriptors?

[Naresh]

Does anyone have a working example of saving the FilterDescriptors collection (say to XML) and then reloading it?

We have a requirement to allow the users to save their filter expressions and then re-use them later.

Any help would be appreciated.

Thanks,
Brian

Hi Brian,

Currently we do not have such an example, but this forum post can help you.

Each FilterDescriptor has only 5 properties:

string Member
FilterOperator Operator
object Value
Type MemberType
bool IsCaseSensitive

So, you can traverse the filter descriptors tree recursively and store these values in XML. For the CompositeFilterDescriptors that you encounter you should store the LogicalOperator property.

Then do the opposite by reading the XML and reconstructing the tree.

I hope this helps.
