This problem existing for a long time. I have not fix it.
The page have a datagrid. the view type is scrollview, When search not exist in my database query. I click the doSearchPage2(). I found out the datagrid refresh(load) twice.If search the data exist,the datagrid load once,it's normal.

Code:

<div id="tb2" style="padding:0px;height:auto">
    <div>
        Type Name: <input id="btntypename" class="easyui-textbox pagetextbox" type="text">
        <a id="btnLoad2" href="#" class="easyui-linkbutton" iconcls="icon-search" onclick="doSearchPage2()">Query1</a>
    </div>
</div>

<div id="tb" style="padding:0px;height:auto">
    <div>
        Code: <input id="btnum" class="easyui-textbox pagetextbox" type="text">
        Name: <input id="btnname" class="easyui-textbox pagetextbox" type="text">
        <a id="btnLoad" href="#" class="easyui-linkbutton" iconcls="icon-search" onclick="doSearchPage()">Query2</a>
    </div>
</div>

<div id="main_layout" class="easyui-layout" style="width:100%;height:100%;">
    <div id="p" data-options="region:'west',split:true" title="List" style="width:25%;padding:0px">
        <div id="gridtype" inline="true"></div>
    </div>
    <div data-options="region:'center'" title="Detail">
        
    </div>
</div>

Code:

   $(function () {
        $('#gridtype').datagrid({
            title: '',
            url: '/Box/BaseDetail/TypeReload',
            method: 'get',
            dataType: "json",
            fit: true,
            toolbar: '#tb2',
            fitColumns: true,
            rownumbers: true,
            striped: true,
            view: scrollview,
            autoRowHeight: false,
            remoteSort: false,
            columns: [[
                { field: 'type_number', title: 'Type Code', width: '100px', sortable: true },
                { field: 'type_name', title: 'Type Name', width: '100px', sortable: true }
            ]],
            queryParams: {
                typenumber: '',
                typename: $('#btntypename').val()
            },
            singleSelect: true,
            onLoadSuccess: function (data2) {
                if (data2.rows.length > 0) {
                    $(this).datagrid("selectRow", 0);
                }
            },
            onClickRow: function (rowIndex, rowData) {
                doSearchPage();
            }
        });

   });

   function doSearchPage2() {
        $("#gridtype").datagrid('load', {
            typenumber: '',
            typename: $('#btntypename').val()
        });
    }

    function doSearchPage() {
       //omit code 
    }
