<asp:UpdatePanel ID="VotePanel" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false"> 
    <ContentTemplate> 
     <div class="row"> 
      <!-- left column --> 
      <div class="col-lg-12 col-sm-12 col-xs-12"> 
       <div class="text-center"> 
        <h1> 
         <asp:Label ID="LikeLabel" runat="server" Text="Label"></asp:Label> 
         <br /> 
         <asp:Label ID="DislikeLabel" runat="server" Text="Label"></asp:Label> 
         <br /> 
         <div class="btn-group"> 
          <asp:Button ID="LikeButton" runat="server" CssClass="btn btn-default" Text="Like" 
           OnClick="LikeButton_Click" /><asp:Button ID="UnlikeButton" CssClass="btn btn-default" 
            runat="server" Text="Dislike" OnClick="UnlikeButton_Click" /> 
         </div> 
       </div> 
      </div> 
     </div> 
    </ContentTemplate> 
    <Triggers> 
     <asp:AsyncPostBackTrigger ControlID="LikeButton" /> 
     <asp:AsyncPostBackTrigger ControlID="UnlikeButton" /> 
    </Triggers> 
</asp:UpdatePanel>

Wenn ich diese Seite und klicken Sie auf Schaltfläche ausführen, es es zwei Mal implementiert und dergleichen wird um 2 erhöht Bitte helfen Ich mit der Lösung, so dass das Gleiche nur um eins erhöht wird. Das wird ein großer Gefallen sein. Danke im Voraus! das sind meine gespeicherten Prozeduren:

ALTER procedure [dbo].[InsertUnlike&getLikeDislike] 
(
@id int 
) 
as 
begin 
update QuestionTable 
set Dislikes=Dislikes + 1 where QuestionId=@id; 
select Likes, Dislikes from QuestionTable where QuestionId=@id 
end 

ALTER procedure [dbo].[InsertLike&getLikeDislike] 
(
@id int 
) 
as 
begin 
update QuestionTable 
set Likes=Likes + 1 where QuestionId=@id; 
select Likes, Dislikes from QuestionTable where QuestionId=@id 
end 

ALTER procedure [dbo].[GetQuestionLikeDislike] 
(
@id int 
) 
as 
begin 
select Likes, Dislikes from QuestionTable where QuestionId=@id 
end

Verfahren aktualisiert

ALTER procedure [dbo].[InsertUnlike&getLikeDislike] 
(
@id int 
) 
as 
begin 
update QuestionTable 
set Dislikes=Dislikes + 1 where QuestionId=@id; 
select Likes, Dislikes from QuestionTable where QuestionId=@id 
end 

ALTER procedure [dbo].[InsertLike&getLikeDislike] 
(
@id int 
) 
as 
begin 
update QuestionTable 
set Likes=Likes + 1 where QuestionId=@id; 
select Likes, Dislikes from QuestionTable where QuestionId=@id 
end 

ALTER procedure [dbo].[GetQuestionLikeDislike] 
(
@id int 
) 
as 
begin 
select Likes, Dislikes from QuestionTable where QuestionId=@id 
end 

und entfernte die ChildAsTriggers-Eigenschaft aus dem Aktualisierungsfenster. Es funktionierte! :)

Ändern Sie Ihre Seite zu laden Methode als unten,

protected void Page_Load(object sender, EventArgs e) 
{ 
    if (!IsPostBack) 
    { 
     cl = new ConnectionClass(); 
     QuestonId = Request.QueryString["Id"]; 
     string[] var = { "@id" }; 
     SqlDbType[] type = { SqlDbType.Int }; 
     string[] value = { QuestonId }; 
     dt1 = cl.DatatableProcedure("GetQuestionLikeDislike", var, type, value); 
     LikeLabel.Text = dt1.Rows[0].ItemArray[0].ToString(); 
     DislikeLabel.Text = dt1.Rows[0].ItemArray[1].ToString(); 
     dt = cl.DatatableProcedure("GetAnswers", var, type, value);   
    }  
}
