            dt = WCFService.Host_Getstillneedsquantity(Session["hunqid"].ToString());
             //First grid
            foreach (DataListItem item12 in dMainCategory.Items)
            {
                DataList repHotDeals = (DataList)item12.FindControl("repHotDeals");

                //DataList repHotDeals = sender as DataList;
                foreach (DataListItem item in repHotDeals.Items)
                {
                    ModelId = Convert.ToInt32(((HiddenField)item.FindControl("hfddlmodelid")).Value);
                    int prevQty = 0;
                    int prevStillneedsQty = 0; //nag written..
                   
                    DataRow[] dr = dt.Select("id=" + ModelId);
                    prevQty = Convert.ToInt32(dr[0]["Quantity"].ToString());
                    prevStillneedsQty = Convert.ToInt32(dr[0]["stillneedsQuantity"].ToString()); 

                    TextBox quantityrequired = ((TextBox)item.FindControl("txtquantity"));
                    ViewState["txtquant"] = quantityrequired.Text;

                    Label SellingPrice = (Label)item.FindControl("lblsellingprice");
                    Label lblamount = (Label)item.FindControl("lblamount");

                    if (quantityrequired.Text != "" && int.Parse(quantityrequired.Text) >= prevQty)
                    {                  
                        int PurchasedQty = prevQty - prevStillneedsQty;                                             
                        int diffQnty = Convert.ToInt32(quantityrequired.Text) - prevQty;
                        int NewStillNeedsQnty = diffQnty + prevStillneedsQty;
                        WCFService.UpdateQuantity1(ModelId, Session["hunqid"].ToString(), Convert.ToInt32(quantityrequired.Text), NewStillNeedsQnty);

                    }
                    else
                    {
                        lblordsum.Visible = true;
                        lblordsum.Text = "Quantity Should Not Less than Purchased Quantity or Zero";
                        lblordsum.ForeColor = System.Drawing.Color.Red;
                    }
                    
                }

            lblordsum.ForeColor = System.Drawing.Color.Green;
        }
        catch (Exception ex)
        {
            WCFService.User_LogError("HostCollections", "lbtnAddtoCart_Click", (ex.InnerException != null) ? ex.InnerException.ToString() : ex.Message.ToString(), 4, 4);
        }
    }

推荐答案

要循环内部网格，可以使用以下代码（单击时）在按钮上）





gvMainGrid是父网格

gvInnerGrid是子网格



使用以下代码，您可以遍历任何控件。

For looping through the inner grid, you can use the below code (when clicking on a button)


gvMainGrid is the parent grid
gvInnerGrid is the child grid

Using the below code you can loop through any controls.

protected void btnUpdate_Click(object sender, EventArgs e)
       {
           for (int i = 0; i < gvMainGrid.Rows.Count; i++)
           {
               for (int j = 0; j < ((GridView)gv.Rows[i].FindControl("gvInnerGrid")).Rows.Count; j++)
               {
                   ((TextBox)((GridView)gvMainGrid.Rows[i].FindControl("gvInnerGrid")).Rows[j].FindControl("txtSNo")).Text = "100";

               }
           }
       }

希望这对你有帮助。
