refresh button in grid is not loading data for current dataitems ,if we use Kendo Grid + DropDownlist

[Swarna Priya]

Hi All,

I am using one grid and dropdown list. whenever the dropdown list changes then grid should get reloaded with new. it is working fine for me if i use below code in the drop down change event, but i have made the default refresh button of grid as true.

Hence when i click on refresh button in grid it is not loading with data for current dataitem selected in dropdown. it is only loading the which got loaded in grid for the first time.
please reply ASAP , as this is stopping my work.
change: function (e) {
                    $("#" + gridname).data("kendoGrid").dataSource.read(getAuditparamter("WorkDetails"));
                    }
 $('#' + gridname).kendoGrid({
                dataSource: {
                    transport: {
                        read: {
                            url: window.environment.siteRootUrl + "url",
                            data: getAuditparamter(gridName),
                            dataType: "json",
                            cache: false
                        }
                    },
                    pageSize: 25,
                    serverPaging: true,
                    sort: {
                        field: "EventDate",
                        dir: "desc"
                    }
                }

  function getAuditparamter(gridname) {
            
            if (gridname == "WorkDetails") {
                var ddlTaskName = $("#ddl" + gridName).data("kendoDropDownList").text();
                return { id : workId,taskName: ddlTaskName.trim()};
                
            }
        }

Hello Swarna,

Currently you are passing the parameter through the read method. The problem however is that the build-in refresh button calls the read method without parameters.

In order to resolve the issue I suggest to use the parameterMap of the DataSource to add the DropDownList value to the read request. The parameterMap will execute when you call the read request manually but also when the refresh button calls it.
