I'm looking at using a Data Source with server filtering turned on, but without odata. Is there a simpler URL syntax for filtering in a find-as-you-type scenario? Right now my URL for a filter of "c" looks like:

?filter%5Blogic%5D=and&filter%5Bfilters%5D%5B0%5D%5Bvalue%5D=c&filter%5Bfilters%5D%5B0%5D%5Bfield%5D=&filter%5Bfilters%5D%5B0%5D%5Boperator%5D=startswith&filter%5Bfilters%5D%5B0%5D%5BignoreCase%5D=true

Ideally, I'd like something along the lines of:

?filter=c

Is there an easy way to do this for use with the multi-select widget?

Hi Brian,

Did you set the dataSource type to "odata"? In case you are not using odata please remove this setting from your configuration.

On a side note, to customize the parameters being send to the server you may use the parameterMap function of the dataSource.transport. In case you want to further customize the transport URL you may define it as a function. For more information please check the corresponding documentation:

I am configuring the dataType to "json" but it is certainly using odata as the filter format.

var dataSource = new kendo.data.DataSource({
                serverFiltering: true,
                transport: {
                    read: {
                        dataType: "json",
                        url: "myurl"
                    }
                }
            });

Hi,

this is the default filtering parameter construction for the datasource (not related to odata). You can change it in the parameterMap configuration, like Alexander pointed in his previous reply.

The parameterMap function worked great. I have the following code to pull our the filter value for a multi-select:

parameterMap: function(data, type) {
    if (type == "read" && data.filter) {
        return {
                   query: data.filter.filters[0].value
        }
    }
}
