RowEditing命令沒有觸發

我有一個gridview，可以在footertemplate中添加工作正常的行。我想將RowEditing和RowDeleting添加到網格中。我添加了RowEditing方法，但是當我點擊'編輯'按鈕時，添加行顯示在頁腳中，就像它是「添加行」命令一樣當我創建一個網格原型時，當你點擊按鈕時，行會改變，這樣所有的字段都是可編輯的，當字段是ItemTemplate字段時，我該怎麼做？RowEditing命令沒有觸發

這是我的標記：

這是我的代碼背後：

protected void MappingGridView_RowEditing(object sender, GridViewEditEventArgs e) 
    { 
     MappingGridView.EditIndex = e.NewEditIndex; 
     populateEnrollMappingGrid(); 
    }

當我單擊編輯按鈕時，不會調用RowEditing方法，並且頁腳行顯示插入操作。

如何獲得編輯按鈕以使點擊可編輯的行？

更新的信息的Page_Load 這是Page_Load方法：

protected void Page_Load(object sender, EventArgs e) 
    {   
     try 
     { 
      if (!IsPostBack) 
      { 
       //Get the Environment Setting to determine the database to access 
       txtBoxEnvironment.Text = CurrentEnvironment; 
       DAL.setCurrentEnvironment(CurrentEnvironment); 

       //Get All Section information from database 
       CSectionInfo.getData(); 

       //Get All Mapping informatio from database 
       CEnrollMappingInfo.getData(); 

       //Populate the Mapping grid 
       MappingGridView.DataSource = CEnrollMappingInfo.getInitialData(); 

       //Populate the Drop Down Section List 
       populateDropDownSectionList(CEnrollMappingInfo.SelectedSectionID); 

       //Grid must be bound after the Dropdown List is set so the value in the footer can be determined 
       MappingGridView.DataBind(); 

       //Populate the Section grid 
       SectionGridView.DataSource = CSectionInfo.getDataUsingSectionID(CEnrollMappingInfo.SelectedSectionID); 

       //Get Course information from database 
       populateCourseGrid(); 

       //Populate the Drop Down Course List 
       populateDropDownCourseList(CSectionInfo.SelectedCourseID); 

       //Grid must be bound after the Dropdown List is set so the value in the footer can be determined 
       SectionGridView.DataBind(); 
      } 
     } 
     catch (Exception ex) 
     { 
      logger.ErrorException(ex.Message, ex); 
      Response.Redirect("~/Error.aspx"); 
     } 
    }

感謝。

我解決了問題...

在我的標記，我設置的編輯按鈕CausesValidation = true和ValidationGroup-MappingGrid這是插入驗證在頁腳中的內容。爲了更正，我將CausesValidation設置爲false並刪除了ValidationGroup。

我在更新按鈕字段中設置這些值。

現在工作！

謝謝。

只是猜測，你是在每回發數據綁定GridView。

你有Page_Load類似於：

protected void Page_Load(object sender, EventArgs e) 
{   
    populateEnrollMappingGrid(); // a method where you assign the DataSource and call grid.DataBind() 
}

使用IsPostBack屬性：

protected void Page_Load(object sender, EventArgs e) 
{  
    if(!IsPostBack)  
     populateEnrollMappingGrid(); 
}

我添加了Page_Load方法。我有3個網格。但映射網格填充（！IsPostBack） –

我不明白何時方法MappingGridView_RowEditing不被調用，當我點擊'編輯'按鈕。我已經按照這個函數的教程。我有一個使用CommandField進行編輯的原型，並且工作正常。 TemplateField是否應該更改回CommandField？ –

RowEditing命令沒有觸發
