Answer 1

Use the filterMenuInit event of the grid. Then find the numeric textbox and set its min value to 0 using the min method. Here is a sample implementation:

  <div id="grid"></div>
  <script>
  $("#grid").kendoGrid({
    dataSource:{ 
      data: [ 
        { name: "Jane Doe", age: 30 },
        { name: "Jane Doe", age: 33 }      
      ],
      schema: {
        model: {
          fields: {
            age: { type: "number" }
          }
        }
      }
    },
    filterable: {
      extra: false
    },
    filterMenuInit: function(e) {
      var numeric = e.container.find("[data-role=numerictextbox]").data("kendoNumericTextBox");
      if (numeric) {
        numeric.min(0);
      }
    }
  });
  </script>
