Refresh/Update Controls inside usercontrol

I have a form that has TabControl with Dynamic TabPages in it. Each pages has usercontrol added using a loop. This is how I add the usercontrol in each pages.

for (var i = 0; i < tbl.Rows.Count; i++)
{
    uctrTab = new XtraTabPagesUserCtrl();
    xtab.TabPages[i].Text = "Table " + (i+1);
    uctrTab.LayoutClicked += new MouseEventHandler(Layout_Click);
    xtab.TabPages[i].Controls.Add(uctrTab);
    xtab.TabPages[i].PageVisible = !xtab.TabPages[i].PageVisible;
}

The usercontrol I made has a DataGridView in it so i want to refresh the content of it but I dont know how to do that without removing and readding the control back.

right now my solution is

 xtab.SelectedTabPage.Controls.Clear();
 uctrTab = new XtraTabPagesUserCtrl();
 uctrTab.LayoutClicked += new MouseEventHandler(Layout_Click);
 xtab.SelectedTabPage.Controls.Add(uctrTab);

is there any better way of refreshing the content without having to do that?

I'm going to write my answer here (I did it in the comments section because question was on hold).

My suggestion.. first implement a method in your user control like.. 

public void RefreshGrid()
{
    refresh datagridview data here
}

Second, itearate over selected tab page's controls and look for your usercontrol.. something like this.. 

foreach(Control ctrl in selectedTabPage.Controls)
{ 
    if(ctrl is XtraTabPagesUserCtrl)
    { 
        ((XtraTabPagesUserCtrl)ctrl).RefreshGrid(); 
    } 
}
