c# - Telerik Radgrid 的 CRUD 操作（插入、更新、删除）按 MVP 模式

Question

我在 ASP.Net 页面中有一个Telerik RadGrid，我想在 MVP 模式的演示者中处理 CRUD 事件处理程序。

// ASPX page
<telerik:RadGrid ID="RadGrid1" runat="server" 
         onupdatecommand="RadGrid1_UpdateCommand">               
</telerik:RadGrid>

// Asp.Net Code Behind
protected void RadGrid1_UpdateCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
     // do update
}

Answer 1

我的答案很简单，根据我的搜索，我们必须在演示者中处理网格的事件（InsertCommand、UpdateCommand、DeleteCommand），如下所示：

// view interface
public interface IGridView 
{
    Telerik.Web.UI.RadGrid myGrid { get; }
}

// presenter
protected readonly IGridView _view;

public GridPresenter(IGridView view)
{
    _view = view;

    _view.myGrid.UpdateCommand += new Telerik.Web.UI.GridCommandEventHandler(onUpdateCommand);
    _view.myGrid.InsertCommand += new Telerik.Web.UI.GridCommandEventHandler(onInsertCommand);
    _view.myGrid.EditCommand += new Telerik.Web.UI.GridCommandEventHandler(onEditCommand);
}

private void onUpdateCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
    // Code for updating 
}

private void onInsertCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
    // Code for inserting
}

private void onEditCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
    // Code for editcommand
}
