Cannot keep settings of RadGrid

[ysea]

My situation :
My Web Page has many Tab (dynamic tabs) and 1 RadGrid (grid).  When I changed position tab, grid auto generate dynamic columns.
(I must set property grid.MasterTableView.EnableViewState = false to create dynamic columns). But I can't keep settings of gird when changed to another page and move back

My code :
<code>
private int tabIndex = 0;       // variable to define tab is selected
protected void Page_Init(....)
{
          if(! string.IsNullOrEmpty(Request.QueryString["tabIndex"] )
          {
                    tabIndex = Convert.ToInt32(Request.QueryString["tabIndex"]);
          }
          else
                   tabIndex = 0;
         
          // This method create grid corresponding tab is selected
          CreateGrid(tabIndex);
}

protected void OnUnload(....)
{
       GridPersistSetting gridSetting = new GridPersistSetting (grid);
       Session["grid" + tabIndex] = gridSetting.SaveSettings();
}

protected voi Page_Load(....)
{
        if (!IsPostBack)
        {
                  ....................
                  if(Session["grid" + tablndex] !=null)
                  {
                              GridPersistSetting gridSetting = new GridPersistSetting (grid);
                              gridSetting.LoadSettings(Session["grid" + tabIndex].ToString());
                  }
        }
}

protected void Tab_Click(...)
{
         Response.Redirect("Demo.aspx?tabIndex = " + e.tabIndex)
}
</code>

I do same as your example (gridSetting.LoadSettings() in Page_Init() and and gridSetting.SaveSettings in Render()) but it not success so I must changed as above (on PageLoad and UnLoad)
Can you give me a solution ?
Thanks you.

Thanks for your reply
I've examined this topic but it cannot help me solve my problem.
My problem is grid.MasterTableView.EnableViewState = false so when method SaveSettings() cannot get settings value changes.

Hi Phi,

The NextPrevAndNumeric grid pager type requires the viewstate of the control to be enabled.  If you are using this pager type a possible solution for your case would be to store the grid viewstate in the Session (after it is enabled) as explained in this documentation topic.

I've seen "Saving the grid ViewState in Session" and I found value of ViewState is keep on PageStatePersiste but still EnableViewState = true
