  Hi akhterr,

  Nice to see you again.

  You are missing dt.Columns.Add("Codeitem"); in your Page_Load event.

  Please refer to below:

  protected void Page_Load(object sender, EventArgs e)
          {
              if (!this.IsPostBack)
              {
                  dt.Columns.Add("Descriptionitem");
                  dt.Columns.Add("Codeitem");
                  dt.Columns.Add("QTY");
                  ViewState["dt"] = dt;
                  itemload();
              }
          }

  Best Regard,

  Yang Shen

  giving error on that (Input string was not in a correct format.)

  codeitem = int.Parse(row["Codeitem"].ToString());

  Note : i did not mentioned codeitem column in gridview?

  Hi,

  You fixed the previous error ?

  Look at the value for row["Codeitem"].ToString(). It means that this value can't be parsed to an int. If the db side column is already an int you could cast directly the column  or use https://docs.microsoft.com/en-us/dotnet/api/system.data.datarowextensions?view=netframework-4.8 to write direcly:

  codeitem=row.Field<int>("Codeitem");

  More likely this is a (n)varchar column which is supposed to contain integers (but apparently not always)  ?

  Not directly related but if starting with web forms you may want to have a look at https://docs.microsoft.com/en-us/aspnet/web-forms/overview/presenting-and-managing-data/model-binding/retrieving-data which is late to the party (new in 4.5) but can be interesting compared with older approach...

  Hi akhterr,

  akhterr

  protected void GVadd_Click(object sender, EventArgs e)
  {
      dt = ViewState["dt"] as DataTable;
      dr = dt.NewRow();
    //  dr["Codeitem"] = DropDownList1.SelectedValue;
      dr["Descriptionitem"] = DropDownList1.SelectedItem.Text.Trim();
  
      dr["QTY"] = txtqty.Text;
      dt.Rows.Add(dr);
      GridView1.DataSource = dt;
      GridView1.DataBind();
      clear();
  }

  // dr["Codeitem"] = DropDownList1.SelectedValue;

  It seems you comment on this code? 

  dt.Columns.Add("CodeItem"); will add your datable a new CodeItem column but with null value which you can't convert to int.

  Please cancel the comment and try again.

  Best Regard,
