Postback will disappear , Every postback need to create again.

a. Generate GridView

public GridView GenerateGridView(int m_instanceCount)

{

    GridView newGridView = new GridView();

    newGridView.ID = GvBroadcastTitle.ID + m_instanceCount;

    newGridView.CssClass = "tabsummary";

    newGridView.GridLines = GridLines.None;

    newGridView.AlternatingRowStyle.CssClass = "alt";

    newGridView.AutoGenerateColumns = false;

    newGridView.AllowPaging = false;

    newGridView.CellSpacing = 1;

    newGridView.PageIndexChanging += new GridViewPageEventHandler(GvTitle_PageIndexChanging);

    newGridView.RowCommand += new GridViewCommandEventHandler(GvTitle _RowCommand);

    //Title ItemTemplate

    templateField titleField = new TemplateField();

    titleField.HeaderText = "Title";

    titleField.ItemTemplate = new AddTitleTemplateToGridView();

    newGridView.Columns.Add(titleField);

    // Bound Field

    foreach (DataControlField dc in GvTitle.Columns)

    {

      if (dc.GetType() == typeof(BoundField))

      {

        BoundField col = new BoundField();

        col.DataField = ((BoundField)dc).DataField;

        col.HeaderText = dc.HeaderText;

        newGridView.Columns.Add(col);

       }

     }

       return newGridView;

}

public class AddTitleTemplateToGridView : ITemplate

{

     LinkButton ht = new LinkButton();

     public AddTitleTemplateToGridView(){ }

     public virtual void OnInit(object sender, EventArgs e){ }

           

           

     void ITemplate.InstantiateIn(System.Web.UI.Control container)

     {

        ht = new LinkButton();

        ht.CommandName = "viewTitle";

        ht.Init += new EventHandler(OnInit);

        ht.DataBinding += new EventHandler(ht_DataBinding);

        container.Controls.Add(ht);

     }

     void ht_DataBinding(object sender, EventArgs e)

     {

        LinkButton lnk = sender as LinkButton;

        GridViewRow container = lnk.NamingContainer as GridViewRow;

        object dataValue = DataBinder.Eval(container.DataItem, "Title");

        if (dataValue != null)

        {

            lnk.Text = dataValue.ToString();

            lnk.CommandArgument = dataValue.ToString();

         }

b. Generate GridView

public GridView CopyGridView(GridView gridview, int m_instanceCount)

{

     Type t = gridview.GetType();

     GridView newGridView = (GridView)t.InvokeMember("", BindingFlags.CreateInstance, null, null, null);

     foreach (PropertyInfo prop in t.GetProperties())

     {

        if (prop.CanWrite)

        {

           if (prop.Name == "ID")

                 newGridView.ID = gridview.ID + m_instanceCount;

           else

                 prop.SetValue(newGridView, prop.GetValue(gridview, null), null);

        }

     }

     foreach (DataControlField item in gridview.Columns)

     {

          newGridView.Columns.Add(item);

     }

   

    newGridView.AlternatingRowStyle.CssClass = "alt";

    newGridView.RowCommand += new GridViewCommandEventHandler(GvTitle_RowCommand);               

     return newGridView;

}
