我无法从孩子gridview的文本框的值。 其showes错误，此（gridview id）在当前上下文中不存在。 其中在父Gridview中工作正常。当我尝试与父Gridview 那么它的工作很好，意味着代码是正确的。我做的方式。可能是worng 所以请检查。设计部分和.cs部分均已发布。我还提到我在哪里得到错误

protected void gvOrders_RowCommand(object sender, GridViewCommandEventArgs e) 
    { 



     if (e.CommandName == "Save") 
     { 
       int rowIndex = Convert.ToInt32(e.CommandArgument); 
       **GridViewRow row = gvOrders.Rows[rowIndex];** // Here i am getting error that gvOrders does not exit in the current context 

       //GridView GVCollapse = (GridView)sender; //find nested grid view 
       //GridViewRow row = (GridViewRow)GVCollapse.Parent.Parent; 

       //Fetch value of Name. 
       string Journal = (row.FindControl("txtJournalName") as TextBox).Text; 
       string Volume = (row.FindControl("txtVolume") as TextBox).Text; 
       string Issues = (row.FindControl("txtIssues") as TextBox).Text; 
       string DispatchDate = (row1.FindControl("txtDispatchDate") as TextBox).Text; 
       string Remarks = (row.FindControl("txtRemarks") as TextBox).Text; 



       ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('Name: " + Journal + "\\nCountry: " + Volume + "\\nDate: " + DispatchDate + "');", true); 



     } 
    }

巴顿更换ButtonField字段：

<asp:TemplateField HeaderText="Save"> 
    <ItemTemplate> 
     <asp:Button ID="btnSave" CommandName="Save" runat="server" Text="Save" /> 
    </ItemTemplate> 
</asp:TemplateField> 

在RowCommand事件试试吧：

if (e.CommandName == "Save") 
{ 
    GridViewRow row = (GridViewRow)(((Button)e.CommandSource).NamingContainer); 
    GridView gv = (GridView)row.FindControl("gvOrders"); 

    string Journal = (row.FindControl("txtJournalName") as TextBox).Text; 
    //... some other code 
}
