Scenario: 

1 Filter being used to filter 2 different Grids in 2 different TabStrip tabs

The issue can be reproduced in the following demo - Grid - Declarative Binding

Steps:

• In the RadGrid bound to WCF Web Service initially apply "NoFilter" to one column.
• Apply any random filter to another column of the Grid and monitor the DevTools Consol for the error

See http://somup.com/cYjZIU6NG9

Currently when trying to use datatype of a Nullable Decimal with a RadFilter, when applying the expression an invalid cast exception is thrown due to Nullable Decimals not being support and the fallback DataType of Double being used when using a RadFilterNumericFieldEditor.

I would like RadFilterNumericFieldEditor to support DataType of Nullable Decimal.

It would be extremely useful if a RadFilterDropDownEditor could expose a DataSource property and a DataBind method to facilitate typical database binding operations. Only allowing the use of a SqlDataSource goes against the concept of separation of duties and forces SQL to be maintained in two places rather than in one Data Layer.

Change the RadFilter search algorithm from DFS to search the “closest" control algorithm

DateTime format in RadGrid.MasterTableView.FilterExpression is currently not able to change.

Hi,

It seems there is no built in feature in RadFilter Control to populate the filters in Combobox, and seems like its using Context Menu now. The problem is, we are populating large number of filters (>50) and navigating through the context menu to look for particular filter is painful.

We are requesting a feature to have the filters populated in something like Typeahead Combobox. (Please see attached screenshot)
