從gridview捕捉id到fillgridview

我在一個頁面上有兩個gridview ..我列出第一個比從commandargument（「id」）我列出的第二個..但我正在做這些gridviews我可以完成第一個gridview，因爲它沒有必要趕上id來列出它。它列出了它所有的。但第二個，我想列出該產品的類別。你可以幫我嗎？和單詞的翻譯;從gridview捕捉id到fillgridview

Doldur：填充/ Guncelle：更新/ SIL：刪除/ vazgec：取消

錯誤的地方是全問號。感謝您的幫助

 private void Doldur() 
    { 
     WebHelper.FillGridView(myGrid, Service.GetAllCategories()); 
    } 

    protected void Page_Load(object sender, EventArgs e) 
    { 
     if (IsPostBack) 
      return; 

     Doldur(); 
    } 


    protected void myGrid_RowCommand(object sender, GridViewCommandEventArgs e) 
    { 
     GridViewRow row = null; 

     if (e.CommandSource is ImageButton) 
     { 
      row = ((e.CommandSource as ImageButton).NamingContainer) as GridViewRow; 
     } 

     int id = 0; 

     int.TryParse(e.CommandArgument.ToString(), out id); 

     switch (e.CommandName) 
     { 
      case "sil": 
       Service.Sil(id); 
       break; 
      case "guncelle": 
       // textbox'ı yakalamak için 
       TextBox txtKategoriAd = myGrid.Rows[row.RowIndex].FindControl("txtKategoriAd") as TextBox; 
       var kategori = new Categories { CategoryID = id, CategoryName = txtKategoriAd.Text }; 
       Service.Update(kategori); 
       // Edit moddan çıkılmalı.. 
       myGrid.EditIndex = -1; 
       break; 
      case "vazgec": 
       myGrid.EditIndex = -1; 
       break; 
      case "link": 
       int categoryId = Convert.ToInt32(e.CommandArgument); 
       myGrid2.DataSource = Service.GetProductsByCategories(categoryId); 
       myGrid2.DataBind(); 
       break; 
     } 

     Doldur(); 
    } 
    protected void myGrid_RowEditing(object sender, GridViewEditEventArgs e) 
    { 
     myGrid.EditIndex = e.NewEditIndex; 
     Doldur(); 
    } 

    private void Doldur2() 
    { 
     WebHelper.FillGridView(myGrid2, Service.GetProductsByCategories(??????)); 
    } 

    protected void myGrid2_RowCommand(object sender, GridViewCommandEventArgs e) 
    { 
     GridViewRow row = null; 

     if (e.CommandSource is ImageButton) 
     { 
      row = ((e.CommandSource as ImageButton).NamingContainer) as GridViewRow; 
     } 

     int id = 0; 

     int.TryParse(e.CommandArgument.ToString(), out id); 

     switch (e.CommandName) 
     { 
      case "sil2": 
       Service.Sil2(id); 
       break; 
      case "guncelle2": 
       // textbox'ı yakalamak için 
       TextBox txtKategoriAd2 = myGrid2.Rows[row.RowIndex].FindControl("txtKategoriAd2") as TextBox; 
       var product = new Products { ProductID = id, ProductName = txtKategoriAd2.Text }; 
       Service.Update2(product); 
       // Edit moddan çıkılmalı.. 
       myGrid2.EditIndex = -1; 
       break; 
      case "vazgec2": 
       myGrid2.EditIndex = -1; 
       break; 
     } 

     Doldur2(); 
    } 
    protected void myGrid2_RowEditing(object sender, GridViewEditEventArgs e) 
    { 
     myGrid2.EditIndex = e.NewEditIndex; 
     Doldur2(); 
    } 
}

您應該保存第二個網格的類別ID。

case "link": 
       int categoryId = Convert.ToInt32(e.CommandArgument); 
       Session["CategoryID"] = categoryId; 
       myGrid2.DataSource = Service.GetProductsByCategories(categoryId); 
       myGrid2.DataBind(); 
       break;

和

private void Doldur2() 
    { 
     int catid = (int)Session["CategoryID"]; 
     WebHelper.FillGridView(myGrid2, Service.GetProductsByCategories(catid)); 
    }

多數民衆贊成。
