data = "[{"SecurityGroupID":31,"SecurityGroupName":"Permission Testers","UserID":30,"Name":"Dawn Test'Neil"},{"SecurityGroupID":31,"SecurityGroupName":"Permission Testers","UserID":213,"Name":"Dawn 2 Bates"}]"

为了解决这个问题，我稍微改变了方法，使用了数据源传输。一切正常。解决方案如下所示

function DisplayCommentDialog(EntityOrganizationID) {
    var categories = $("#commentrecipients").kendoDropDownList({
        optionLabel: "Select Recipients...",
        dataTextField: "Name",
        dataValueField: "UserID",
        height: 310,
        Width: "900px",
        dataSource: {
            transport: {
                read: function (options) {
                    $.ajax({
                        url: "/Submission/SecurityGroupsUsersAccessRight",
                        dataType: "JSON", // "jsonp" is required for cross-domain requests; use "json" for same-domain requests
                        data: {
                            id: EntityOrganizationID
                        },
                        success: function (result) {
                            // notify the data source that the request succeeded
                            options.success(result);
                        },
                        error: function (result) {
                            // notify the data source that the request failed
                            options.error(result);
                        }
                    });
                }
            }
        }
    }).data("kendoDropDownList");
}

data = "[{"SecurityGroupID":31,"SecurityGroupName":"Permission Testers","UserID":30,"Name":"Dawn Test'Neil"},{"SecurityGroupID":31,"SecurityGroupName":"Permission Testers","UserID":213,"Name":"Dawn 2 Bates"}]"

function DisplayCommentDialog(EntityOrganizationID) {
    var categories = $("#commentrecipients").kendoDropDownList({
        optionLabel: "Select Recipients...",
        dataTextField: "Name",
        dataValueField: "UserID",
        height: 310,
        Width: "900px",
        dataSource: {
            transport: {
                read: function (options) {
                    $.ajax({
                        url: "/Submission/SecurityGroupsUsersAccessRight",
                        dataType: "JSON", // "jsonp" is required for cross-domain requests; use "json" for same-domain requests
                        data: {
                            id: EntityOrganizationID
                        },
                        success: function (result) {
                            // notify the data source that the request succeeded
                            options.success(result);
                        },
                        error: function (result) {
                            // notify the data source that the request failed
                            options.error(result);
                        }
                    });
                }
            }
        }
    }).data("kendoDropDownList");
}
