如何將值傳遞到c＃中的圖像按鈕單擊事件？

Question

嘗試將一些值傳遞給圖像按鈕單擊事件，如下所示：

<asp:ImageButton id="imagebutton1" runat="server" AlternateText="5 Star Luxury Villas in North Cyprus" ImageUrl="/download/1/luxury_villas.jpg" OnClick="ImageButton_Click('value1', 'value2')"/>

然后在代碼背后：

    protected void ImageButton_Click(object sender, ImageClickEventArgs e, string value1, string value2)
    {
       Response.Write(Value2);
    }

Answer 1

嘗試使用OnCommand而不是OnClick

然后，您可以在CommandName和CommandArgument屬性中指定值

<asp:ImageButton ID="blah" runat="server" OnCommand="blah_command" CommandName="val1" CommandArgument="val2,val3,val4" />

和

protected void blah_Command(object sender, CommandEventArgs e)
{
    string val1 = e.CommandName.ToString();

    string [] othervals = e.CommandArgument.ToString().Split(',');

}
