如何获取动态Gridview文本框模板列值总和

问题描述

你好朋友，

我创建了一个动态网格视图，其中包含3个名为1)项目名称，2)数量，3)价格的文本框.现在我想获取标签中所有价格文本框的总计.

这是在gridview中动态添加新行的代码:-

Hello Friends,

i have create an dynamic grid view with 3 text box named 1) item name, 2)qty , 3)price. now i want to get Total of all the price text box in label.

here is code for dynamic add new row in gridview :-

private void AddNewRowToGrid()
    {
        try
        {
            int rowIndex = 0;

            if (ViewState["CurrentTable"] != null)
            {
                DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"];
                DataRow drCurrentRow = null;
                if (dtCurrentTable.Rows.Count > 0)
                {
                    for (int i = 1; i <= dtCurrentTable.Rows.Count; i++)
                    {
                        //extract the TextBox values
                        TextBox box1 = (TextBox)GrdProduct.Rows[rowIndex].Cells[1].FindControl("txtitemname");
                        TextBox box2 = (TextBox)GrdProduct.Rows[rowIndex].Cells[2].FindControl("txtqty");
                        TextBox box3 = (TextBox)GrdProduct.Rows[rowIndex].Cells[3].FindControl("txtprice");

                        drCurrentRow = dtCurrentTable.NewRow();

                        drCurrentRow["RowNumber"] = i + 1;
                        drCurrentRow["Column1"] = box1.Text;
                        drCurrentRow["Column2"] = box2.Text;
                        drCurrentRow["Column3"] = box3.Text;

                        rowIndex++;
                    }
                    dtCurrentTable.Rows.Add(drCurrentRow);
                    ViewState["CurrentTable"] = dtCurrentTable;

                    GrdProduct.DataSource = dtCurrentTable;
                    GrdProduct.DataBind();
                }
            }
            else
            {
                Response.Write("ViewState is null");
            }

            //Set Previous Data on Postbacks
            SetPreviousData();
        }
        catch (Exception ex)
        {
            lblerror.Visible = true;
            lblerror.InnerText = ex.Message.ToString();
        }
    }

现在，当textbox_changed事件触发时，我希望所有价格合计在一个标签中.

感谢所有人... !!!!

now i want Total of all the Price in one Label when textbox_changed event fire.

Thanx to all...!!!!

推荐答案

function calculateamount() {
      var txtTotal = 0;
        var passed = false;
        total = 0.00;
        var id = 0;
        totalDTH = 0.00;
        totalMCF = 0;
        // Get the gridview
        var grid = document.getElementById("<%= GridView1.ClientID%>");

        // Get all the input controls (can be any DOM element you would like)
        var inputs = grid.getElementsByTagName("input");

        // Loop through all the DOM elements we grabbed
        for (var i = 0; i < inputs.length; i++) {
            // In this case we are looping through all the Dek Volume and then the Mcf volume boxes in the grid and not an individual one and totalling them
            if (inputs[i].name.indexOf("lbl_amt") > 1) {
                if (inputs[i].value != "") {
                    totalDTH = totalDTH + MathRound(parseFloat(inputs[i].value));
                }
            }
        }
        document.getElementById("<%= txtamttotal.ClientID %>").value = MathRound(totalDTH);

    }

if(inputs [i] .name.indexOf("lbl_amt")> 1)//您应在此处使用gridview中价格的文本框.

在keyup或onblur上调用calculateamount()函数


如果对您有帮助，请投票

if (inputs[i].name.indexOf("lbl_amt") > 1) // You should use here textbox of price which is in gridview.

call calculateamount() function on keyup or onblur
