    The common scenario for filter expression is that Column is compared to a value, ex. TransactionId=12345. But can you create an expression that would allow user to specify comparison of 2 fields instead, e.g. TransactionId=CurrentTransactionId?

    Hi Svyatoslav,

    I would suggest you to revise the help topic below that elaborates on this matter:

    Dear Maria,

     

    The link that you suggested does not address the situation I'm talking about. I'll try to explain in more detail...

     

    Let's say I have an entity represented by a table TestTable:

    -----------------------------------------------------------------------------------------

    |  TransactionId  |  AgreementId  |  CurrentTransactionId  |  Value  |

    -----------------------------------------------------------------------------------------

    |              15431  |            12        |                         15433   |        22 |

    |              15432  |            12        |                         15432   |        22 |

    |              15433  |            12        |                         15431   |        22 |

     

    I want to allow user to build a filter that would correspond to the WHERE clause of the following SQL expression :

     

    SELECT *

    FROM TestTable

    WHERE TestTable.TransactionId=TestTable.CurrentTransactionId

     

    Is this something that can be done with Telerik's Filter control?

    Hello,

    Unfortunately the required functionality can not be achieved with the RadFilter control.
    The suggested help topic demonstrates the filter expressions supported by Telerik syntax and you can apply the required SQL syntax per your need.
