        // get date in gridview 
        inp.plandatefrom = datefrom;
        inp.plandateto = dateto;

      DataTable grid = new DataTable();
        DataTable dtf = new DataTable();

grid datatable get the last value

if you have x = 0 and save 1 in x
automatically 0 deleted

this happened in datatable
i want to save each value in one row in datatable

you have written same statement two times..

inf.plandat = DateTime.Parse(row[0].ToString());
grid = inf.gridshowfor();// this method take the date and get result

inf.plandat = DateTime.Parse(row[0].ToString());
grid = inf.gridshowfor();

and you have not assigned the date.inf.plandat to your function inf.gridshowfor()..

check the function inf.gridshowfor()...

Update Your Butshow_Click event as Mentioned Below :

C#

protected void Butshow_Click(object sender, EventArgs e)
      {
          DateTime datefrom = DateTime.Parse(Textfrom.Text);// textbox for date from
          DateTime dateto = DateTime.Parse(Textto.Text);// textbox for date to 
      
          // get date in gridview 
          inp.plandatefrom = datefrom;
          inp.plandateto = dateto;
          dt = inp.gridshow(); // this method used stored peocedure that take from and to date to get date between and worked well 
          GridView1.DataSource = dt;
          GridView1.DataBind();
      
          // here I want to get other value using the  date output from previous datatable "dt"
      
          DataTable grid = new DataTable();
          foreach (DataRow row in dt.Rows)
          {
              DataTable dtf = new DataTable();
      
              inf.plandat = DateTime.Parse(row[0].ToString());
              grid = inf.gridshowfor();// this method take the date and get result
              inf.plandat = DateTime.Parse(row[0].ToString());
      
              dtf = inf.gridshowfor();

              if (grid.Rows.Count == 0)
              {
                  grid = dtf;
              }
              else
              {
                  foreach (var rowToAdd in dtf.Rows)
                  {
                      grid.Rows.Add(rowToAdd);
                  }
              }
          }
      
          GridView2.DataSource = grid;
          GridView2.DataBind(); // here is the problem , the result get one value "last value saved in datatable " 
      }
