GridView編輯點擊2次後觸發事件

我有一個具有編輯/更新功能的GridView。但是，當我點擊一次時，它不會觸發。我必須再次點擊才能觸發。休息部分工作正常。GridView編輯點擊2次後觸發事件

有人可以告訴我發生了什麼事嗎？這裏是我的GV標記：

<asp:GridView ID="gvShowRegistration" runat="server" 
    Height="204px" Width="678px" 
    OnRowEditing = "gvShowRegistration_RowEditing" 
    OnRowUpdating = "gvShowRegistration_RowUpdating" 
    OnRowCancelingEdit = "gvShowRegistration_RowCancelingEdit" CssClass="menu"> 
    <Columns> 
    <asp:CommandField HeaderText="Edit" ShowEditButton="True" ShowHeader="True" ShowSelectButton="True" /> 
    </Columns> 
</asp:GridView> 


public partial class Testing : System.Web.UI.Page 
{ 
    protected void Page_Load(object sender, EventArgs e) 
    { 
      string getEntity = Request.QueryString["EntityID"]; 
      int getIntEntity = Int16.Parse(getEntity); 

      TestLinq2SqlVs1DataContext dt = new TestLinq2SqlVs1DataContext(); 
      var tr = from r in dt.Users 
        join s in dt.Entities on r.Entity_ID equals s.ID 
        where s.ID == getIntEntity 
        select new 
        { 


        }; 

      gvShowRegistration.DataSource = tr; 
      gvShowRegistration.DataBind(); 


    } 



    protected void gvShowRegistration_RowUpdating(object sender, GridViewUpdateEventArgs e) 
    { 
     //Update code goes here!!! 

    } 


    protected void gvShowRegistration_RowEditing(object sender, GridViewEditEventArgs e) 
    { 
     gvShowRegistration.EditIndex = e.NewEditIndex; 

    } 


    protected void gvShowRegistration_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e) 
    { 
     gvShowRegistration.EditIndex = -1; 

    } 


}

當你綁定網格，可能你的網格在回發上被反彈 – kd7 2011-03-23 20:23:58

那麼我該怎麼做？ – 2011-03-23 20:27:14

您的網格在哪個頁面事件中綁定其數據？ – kd7 2011-03-23 20:30:12

我不希望你選擇我的答案，但你應該換你的datacontext的一個using塊：

protected void Page_Load(object sender, EventArgs e) 
{ 
     string getEntity = Request.QueryString["EntityID"]; 
     int getIntEntity = Int16.Parse(getEntity); 
     using (TestLinq2SqlVs1DataContext dt = new TestLinq2SqlVs1DataContext()) 
     { 
      var tr = from r in dt.Users 
        join s in dt.Entities on r.Entity_ID equals s.ID 
        where s.ID == getIntEntity 
        select new 
        { 


        }; 

      gvShowRegistration.DataSource = tr; 
      gvShowRegistration.DataBind(); 
     } 
}

它會自動包裝你的LINQ在一個try/catch塊中並在處理之後處理它。

在另一種方法

private void BindData(int id) 
{ 
      TestLinq2SqlVs1DataContext dt = new TestLinq2SqlVs1DataContext(); 
      var tr = from r in dt.Users 
        join s in dt.Entities on r.Entity_ID equals s.ID 
        where s.ID == id      select new 
        { 


        }; 

      gvShowRegistration.DataSource = tr; 
      gvShowRegistration.DataBind(); 
}

將這個的頁面加載做到這一點：

protected void Page_Load(object sender, EventArgs e) 
{ 
    if (!Page.IsPostback()) 
    { 
     BindData(Request.QueryString["EntityId"]); 
    } 
}

這是隻有一半的修復，是什麼原因導致ENTITYID改變？它會改變回傳嗎？如果是這樣，你將不得不爲此做出調整。

把你已經寫在Page_Load事件中的函數一樣

private void Binddata() 
{ 


     string getEntity = Request.QueryString["EntityID"]; 
     int getIntEntity = Int16.Parse(getEntity); 

     TestLinq2SqlVs1DataContext dt = new TestLinq2SqlVs1DataContext(); 
     var tr = from r in dt.Users 
       join s in dt.Entities on r.Entity_ID equals s.ID 
       where s.ID == getIntEntity 
       select new 
       { 


       }; 

     gvShowRegistration.DataSource = tr; 
     gvShowRegistration.DataBind();

代碼}

而調用這個函數上row_editing和row_cancellingedit這樣的活動

protected void gvShowRegistration_RowEditing(object sender, GridViewEditEventArgs e) 
    { 
     gvShowRegistration.EditIndex = e.NewEditIndex; 
     Binddata(); 
    } 

protected void gvShowRegistration_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e) 
    { 
     gvShowRegistration.EditIndex = -1; 
     Binddata(); 
    }
