Kendo grid filter customizations

[Aiswarya]

How can we customize kendo grid filter options "Is empty","Is not empty" etc like the code which is mentioned below.

.Filterable(filter => filter.Mode(GridFilterMode.Menu).Extra(false)
                                                 .Operators(oper => oper.ForString(str => str.Clear()
                                                                                  .IsEqualTo("Is equal to")
                                                                                  .Contains("Contains")
                                                                                  .StartsWith("Starts with")
                                                                                 )))

Hi Aiswarya,

You can try the following code:

.Filterable(filter => filter.Mode(GridFilterMode.Menu).Extra(false)
    .Operators(oper => oper.ForString(str => str.Clear()
        .IsEqualTo("Is equal to")
        .Contains("Contains")
        .StartsWith("Starts with")
        .IsEmpty("Is empty")
        .IsNotEmpty("Is not empty")
      )
    )
 )

We are adding two new lines after StartWith for the IsEmpty, IsNotEmpty filtering.

I tried the same with 2017.1.223 kendo script release but lead to an error.Do we have to upgrade the kendo.mvc dll?

Hello Aiswarya,

You should update not only the scripts but also kendo.mvc.dll for the 2017.1.223 release. The IsEmpty, IsNotEmpty options are added in this release.

While you are in a trial period you can evaluate the MVC Wrappers for Kendo UI. After this period, you need to buy Kendo UI Complete license in order to be compliant with the license agreements.
