C# 为什么我在尝试将方法附加到按钮单击时收到此错误消息？btnSalvaNota没有重载，单击匹配委托'；EventHandler'；

我对C#和.NET相当陌生，在尝试将按钮更改为SharePoint 2013 Web部件时遇到了一些困难

目前我有这样的想法：

internal class TabAnnotazioni
{
    internal static void CreaTabAnnotazioni(FormProtocolloWebPart.FormProtocolloWebPartUserControl fp, Panel tabPanel, SPListItem item, SPControlMode controlMode, Utente user, Ruolo ruoloUtente, DBConnection dbConfig)
    {
            .......................................................
            .......................................................
            .......................................................

            ImageButton printButton = new ImageButton();
            printButton.ToolTip = "Aggiungi nota";
            printButton.Click += fp.btnSalvaNota_Click;
            printButton.ID = "btnNote";
            printButton.ImageUrl = "/_layouts/15/images/ArxeiaProtocollo/Default/Ribbon/nota.png";
            Label text = new Label();
            text.Text = "Aggiungi nota";
            text.Width = 100;
    }
}

Button printButton = new Button();
printButton.Text = "Aggiungi nota";
printButton.Click += fp.btnSalvaNota_Click;
printButton.CssClass = "shiny-blue";
printButton.ID = "btnNote";

我试图用一个简单的按钮对象替换这个图像按钮。所以我做了这样的事情：

internal class TabAnnotazioni
{
    internal static void CreaTabAnnotazioni(FormProtocolloWebPart.FormProtocolloWebPartUserControl fp, Panel tabPanel, SPListItem item, SPControlMode controlMode, Utente user, Ruolo ruoloUtente, DBConnection dbConfig)
    {
            .......................................................
            .......................................................
            .......................................................

            ImageButton printButton = new ImageButton();
            printButton.ToolTip = "Aggiungi nota";
            printButton.Click += fp.btnSalvaNota_Click;
            printButton.ID = "btnNote";
            printButton.ImageUrl = "/_layouts/15/images/ArxeiaProtocollo/Default/Ribbon/nota.png";
            Label text = new Label();
            text.Text = "Aggiungi nota";
            text.Width = 100;
    }
}

Button printButton = new Button();
printButton.Text = "Aggiungi nota";
printButton.Click += fp.btnSalvaNota_Click;
printButton.CssClass = "shiny-blue";
printButton.ID = "btnNote";

问题出在这一行：

printButton.Click += fp.btnSalvaNota_Click;

Visual Studio突出显示以下错误消息：btnSalvaNota没有重载\u单击匹配委托“EventHandler”

在我的FormProtoCollowBPart.FormProtoCollowBPartUserControl类中，我有以下方法：

internal void btnSalvaNota_Click(object sender, ImageClickEventArgs e)
{
    ....................................................................
    ....................................................................
    ....................................................................
}
