Ext.Net点击GridPanel中一行，在FormPanel里后台加载详细数据

参考官方Demo：GridPanel -> Data With Details - Form Details

其主要过程

1.在GridPanel的SelectionModel段内编写DirectEvents,DirectEvents的子元素RowSelect的OnEvent属性，这里指定了后台调用的方法名称

<SelectionModel>
<ext:RowSelectionModel runat="server" SingleSelect="true">
<DirectEvents>
<RowSelect OnEvent="RowSelect" Buffer="100">
<EventMask ShowMask="true" Target="CustomTarget" CustomTarget="#{FormPanel1}" />
<ExtraParams>
<%-- or can use params[2].id as value --%>
<ext:Parameter Name="EmployeeID" Value="this.getSelected().id" Mode="Raw" />
</ExtraParams>
</RowSelect>
</DirectEvents>
</ext:RowSelectionModel>
</SelectionModel>

2.编写后台功能代码

protected void RowSelect(object sender, DirectEventArgs e)
{
string employeeID = e.ExtraParams["EmployeeID"];

Employee empl = Employee.GetEmployee(int.Parse(employeeID));

this.FormPanel1.SetValues(new {
empl.EmployeeID,
empl.FirstName,
empl.LastName,
empl.Title,
ReportsTo = empl.ReportsTo.HasValue ? (Employee.GetEmployee(empl.ReportsTo.Value).LastName) : "",
empl.HireDate,
empl.Extension,
empl.Address,
empl.City,
empl.PostalCode,
empl.HomePhone,
empl.TitleOfCourtesy,
empl.BirthDate,
empl.Region,
empl.Country,
empl.Notes
});
}
