<asp:Panel ID="Panel1" runat="server"> </asp:Panel>

         DataSet ds = new DataSet();
        ds = obj.GetMedicalGridWithAge(MphID, ProductCode);
        if(ds.Tables.Count > 0)
        {
            if (ds.Tables[1].Rows.Count > 0)
            {
                for (int i = 0; i < ds.Tables.Count; i++)
                {

                    GridView gv = new GridView();
                    gv.ID = "gv" + (i + 1);
                    
                    gv.DataSource = ds.Tables[i];
                    gv.DataBind();
                    Panel1.Controls.Add(gv);
                    Label newLine = new Label(); newLine.Text = "<br/>";
                    Panel1.Controls.Add(newLine);

                }
            }
            else
            {
                GridView gv = new GridView();
                gv.ID = "gv" ;

                gv.DataSource = null;
                gv.DataBind();
                Panel1.Controls.Add(gv);
            }

If I have not understood wrong from title that add multiple grid view dynamically means want to add grid view from code behind at run time.

As GridView is a class in ASP.NET C# and we can create object of it and set its properties just like other class object like follows:

GridView objGV = new GridView();
objGV .AutoGenerateColumns = false;

and can add columns of different type like BoundField and TemplateField from code Like follows:

BoundField field = new BoundField();
field.HeaderText = "Column Header";
field.DataField = Value;
objGV .Columns.Add(field);

and finally can add this grid view object on .aspx under any container control like panel.

PanelId.Controls.Add(objGV );

For adding multiple grid instance just iterate above code in loop like:

for(int i=0;i<yourConditionCount;i++)
{
    GridView objGV = new GridView();
     objGV.ID="GV"+i;   // ID of each grid view must be unique

    // your code logic to set properties and events for grid view

   PanelId.Controls.Add(objGV );
}

Hope I understood your requirement correctly and my explanation will be helpful for you.
