如何找到孩子視野之外的RowDataBound

我拖網格視圖主電網是gridpurchase和兒童電網gvItems如何找到孩子視野之外的RowDataBound

我嘗試導出網格來的Excel文件時隱藏在gvItems一些列。

我曾嘗試下面的代碼，但沒有奏效

導出代碼

protected void btnexcel_Click(object sender, EventArgs e) 
{ 
    gridpurchase.DataSource = po.GetPurchaseOrders(); 
    gridpurchase.DataBind(); 
    GridView gvItems = gridpurchase.FindControl("gvItems") as GridView; 
    gvItems.Columns[0].Visible = false; 
    gridpurchase.GridLines = GridLines.Both; 
    foreach (GridViewRow row in gridpurchase.Rows) 
    { 
     foreach (TableCell cell in row.Cells) 
     { 
      for (int i = cell.Controls.Count - 1; i >= 0; i--) 
      { 
       if (cell.Controls[i] is Image) 
       { 
        Image img = cell.Controls[i] as Image; 


        if (img.ImageUrl.Contains("plus.png") || img.ImageUrl.Contains("minus.png")) 
        { 
         cell.Controls.RemoveAt(i); 
        } 
       } 
      } 
     } 
    } 
    gridpurchase.Caption = "Purchase Orders Report"; 
    System.Web.HttpContext curContext = System.Web.HttpContext.Current; 
    System.IO.StringWriter strWriter = null; 
    System.Web.UI.HtmlTextWriter htmlWriter = null; 
    curContext.Response.Clear(); 
    curContext.Response.Buffer = true; 
    curContext.Response.AddHeader("content-disposition", "attachment; filename=" + System.Web.HttpUtility.UrlEncode("PurchaseOrdersReport", System.Text.Encoding.UTF8) + ".xls"); 
    curContext.Response.ContentType = "application/vnd.ms-excel"; 
    curContext.Response.Write("<meta http-equiv=Content-Type content=text/html;charset=UTF-8>"); 
    strWriter = new System.IO.StringWriter(); 
    htmlWriter = new System.Web.UI.HtmlTextWriter(strWriter); 
    gridpurchase.RenderControl(htmlWriter); 
    curContext.Response.Write(strWriter.ToString()); 
    curContext.Response.End(); 
}

請後剩餘的代碼中刪除第一列如何你正在創建Excel工作表。 –

在導出爲excel之前，您想要從gridview中刪除所有列嗎？ – naveen

根據您的標記，有一個gvItems GridView裏面的每行gridpurchase。您可以在主循環獲取每一個孩子的GridView：

foreach (GridViewRow row in gridpurchase.Rows) 
{ 
    GridView gvItems = row.FindControl("gvItems") as GridView; 
    gvItems.Columns[0].Visible = false; 

    foreach (TableCell cell in row.Cells) 
    { 
     ... 
    } 
}

更改foreach循環這樣

gridpurchase.HeaderRow.Cells[0].Visible = false; 
foreach (GridViewRow row in gridpurchase.Rows) 
{ 
    row.Cells[0].Visible = false; 
}

這將從asp:GridView
