在ASP.NET MVC中单击列时，Kendo网格在空网格上调用read方法

Question

我有一个网格，在点击搜索按钮后加载数据。但是我遇到的问题是，当用户点击任何一列时，它往往会调用数据源读取功能。  是否有任何方法在单击列时停止调用read方法，并且仅在单击搜索按钮时调用read函数？

剃刀：

<div class="col-sm-6">
    <div class="form-group">
        @Html.LabelFor(model => model.EmployeeName, new { @class = "col-sm-4 control-label" })
        <div class="col-sm-8">
            @Html.TextBoxFor(model => model.EmployeeName, new { @class = "form-control"})           
        </div>
    </div>
</div>
<div class="clearfix"></div>
<div class="col-sm-6">
    <div class="form-group">
        <div class="col-sm-8 col-sm-offset-4">
            <input id="btnSearch" type="submit" value="Search" class="btn" />
        </div>
    </div>
</div>


@(Html.Kendo().Grid<Portal.EmployeeViewModel>()
    .Name("GridEmployeeInvitation")
    .Columns(columns =>
    {
        columns.Bound(e => e.EmployeeNumber).Width("160px");
        columns.Bound(e => e.EmployeeName).Width("180px");              
    })
    .Excel(excel => excel

                            .IsNotEqualTo("Is not equal to"))))

                .Read(read => read.Action("GetEmployees", "Admin").Data("GetSearchParameters"))
