问题描述

我想在gridview中显示我通过使用datatable在文本框中输入的数据

我在源代码部分添加了以下内容

i want to display a data in gridview what i have enter in textboxes by using datatable

i have add the following in source part

<form id="form1" runat="server">
  <div>

      <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
      <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
      <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
      <asp:Button ID="Button1" runat="server" onclick="Button1_Click"

          style="height: 26px" Text="Button" />
      <br />
      <br />
      <br />
      <asp:GridView ID="GridView1" runat="server">
      </asp:GridView>
      <br />

  </div>
  </form>

在按钮中单击事件

我已经写了以下代码

in button click event

i have write the following code

{
        DataTable dt = new DataTable(); 
        DataRow dr; 
        dt.Columns.Add("Name");
        dt.Columns.Add("Address"); 
        dt.Columns.Add("Number"); 
        //First fill all the date present in the grid 
        for(int intCnt=0;intCnt<gridview1.rows.count;intcnt++)>
                { 
            if (GridView1.Rows[intCnt].RowType == DataControlRowType.DataRow)
            {
                dr = dt.NewRow();
                dr["Name"] =GridView1.Rows[intCnt].Cells[0].Value; 
                dr["Address"] = GridView1.Rows[intCnt].Cells[1].Value; 
                dr["Number"] = GridView1.Rows[intCnt].Cells[2].Value;
                dt.Rows.Add(dr);
            }
        }
        dr = dt.NewRow();
        dr["Name"] = TextBox1.Text;
        dr["Address"] = TextBox2.Text;
        dr["Number"] = TextBox3.Text;
        dt.Rows.Add(dr); 
       Gridview1.DataSource = dt;
        Gridview1.DataBind();
    }

当我运行asp.net应用程序时

将会发生以下编译错误

when i run the asp.net application

the following compile error will occur

Compiler Error Message: CS1061: 'System.Web.UI.WebControls.TableCell' does not contain a definition for 'Value' and no extension method 'Value' accepting a first argument of type 'System.Web.UI.WebControls.TableCell' could be found (are you missing a using directive or an assembly reference?)

推荐答案

尝试一下，

Try this,

protected void Button1_Click(object sender, EventArgs e)
    {
        DataTable dt = null;
        try
        {
            if (Session["dtItems"] != null)
            {
                dt = (DataTable)Session["dtItems"];
            }
            else
            {
                dt = new DataTable();
                dt.Columns.Add("Quantity");
                dt.Columns.Add("Rate_Unit");
                dt.Columns.Add("Amount");
            }
            DataRow dataRow;
            dataRow = dt.NewRow();
            dataRow["Quantity"] = TextBox1.Text;
            dataRow["Rate_Unit"] = TextBox2.Text;
            dataRow["Amount"] = TextBox3.Text;
            dt.Rows.Add(dataRow);
            dt.AcceptChanges();
            Session["dtItems"] = dt;
            GridView1.DataSource = dt.DefaultView;
            GridView1.DataBind();
        }
        catch (Exception ex)
        {
        }
    }
