I want to bind the combo box to a remote rest service which takes a partial name as query string parameter. Following is the code I have.
So I was hoping when uses types in 3 chars it would emit a call to the service as <serviceUrl>/HpCodes?partialName=tes
but it doesn't seem to be doing that instead it sends the following request
GET <serviceUrl>/HpCodes?partialName=&filter%5Blogic%5D=and&filter%5Bfilters%5D%5B0%5D%5Bfield%5D=Description&filter%5Bfilters%5D%5B0%5D%5Boperator%5D=contains&filter%5Bfilters%5D%5B0%5D%5Bvalue%5D=tes HTTP/1.1
This looks like a oData query annd in my wcf service the partialName is empty string.
Another thing I noticed was that even though I set the minLength to 3 if I click the drop down button with out entering anything the the input area it still calls the service.
$("#combobox").kendoComboBox({ dataTextField: "Description", dataValueField: "Code", filter: "contains", minLength: 3, autoBind: false, dataSource: { type: "json", serverFiltering: true, transport: { read: { url: serviceUrl + "HpCodes", contentType: "application/json; charset=utf-8", dataType: "json", data: { partialName: function () { return $("#combobox").val(); } } } } } });So I was hoping when uses types in 3 chars it would emit a call to the service as <serviceUrl>/HpCodes?partialName=tes

Hello Satish,
Currently we do not prevent binding on the combobox if the input's length is less than the minLength. We will log your request and if other users wants the same functionality we will shedule it for investigation.

You need to modify the transport of the dataSource if you need to send some additional values like this:
transport: { read: { url: serviceUrl + "HpCodes", contentType: "application/json; charset=utf-8", dataType: "json", data: function () { return { partialName: $("#combobox").val() } } } }Currently we do not prevent binding on the combobox if the input's length is less than the minLength.
