Tab positioning control

I have an tabcontrol that hads 5 tabs, tab1, tab2, tab3, tab4, tab5.

each ultratab has its own ugrid, I am trying to write that basically puts the tab first or infront of the tabs where where grids have data or records, but if grids does not have rows or data, put the grid tab last within in the tabcontrol. the customers wants to keep the tab visible at all times.

example

tab1: grid1 has 5 records, tab2: grid2 has 0 records, tab3: grid3 has 0 records, tab4: grid4 has 3 records, tab5: grid5 has 2 records

You are basically shifting all of the tabs with grids with no rows to the end of the tabcontrol

Output:

tab1, tab4, tab5, tab2, tab3.

Try this:

int len = ultraTabControl2.Tabs.Count;

for(int i = len - 2; i >= 0; i--) // iterate backwards, no need to consider last tab
{
UltraTab tabItem = ultraTabControl2.Tabs[i];

foreach (var control in tabItem.TabPage.Controls)
{
if (control is Infragistics.Win.UltraWinGrid.UltraGrid)
{
if (((UltraGrid)control).Rows.Count == 0)
{
ultraTabControl2.Tabs.RemoveAt(i);
ultraTabControl2.Tabs.Add(tabItem); // move to back
}

break; // no need to go on with inner loop
}
}
}

I have the logic have way, im just have a brain freeze , you can replace the infragictics type with the standard type and use a regular winform app with standard controls, logic is the same both ways. Review below.

List tabList = new List();
            int index = 0;
            foreach (UltraTab tabItem in ultraTabControl2.Tabs)
            {
                foreach (var control in tabItem.TabPage.Controls)
                {
                    index++;

                    if (control.GetType() == typeof(Infragistics.Win.UltraWinGrid.UltraGrid))
                    {
                        if (((UltraGrid)control).Rows.Count == 0)
                        {
                            //INSERT GRID
                            ultraTabControl2.TabIndex = index;
                            ultraTabControl2.Controls.Add((UltraGrid)control);
                        }
                        //else
                        //{
                        //    //ADD GRID
                        //    ultraTabControl2.Controls.Add((UltraGrid)control);
                        //}
                    }
                }
            }

Lets start over, There exist a tabcontrol1 already, I just need to manage the 5 existing tabs that are on the tab control base upon if the grid view data on each tab.

so need to create anything new, i just want to basically manage the index of each tab.

So there exist one tabcontrol1 that has five tab, each tab has its on grid view. the tabs that contain grid views with no data move tabs to the back, else move tabs with grid view containing data to the front.

You could create a new tabpage with the same name and delete the old tabpage - copying the controls from page1 to last page that will now be page1

private void button2_Click(object sender, EventArgs e)
{
string title = "TabPage1";
TabPage myTabPage = new TabPage(title);
myTabPage.BackColor = Color.White;
tabControl1.TabPages.Add(myTabPage);

foreach (Control ctl in tabControl1.TabPages[0].Controls)
{
if (ctl is TextBox)
{
TextBox tbox = new TextBox();
tbox.Location = ctl.Location;
tbox.Size = ctl.Size;
myTabPage.Controls.Add(tbox);
}
else if (ctl is Label)
{
Label lbl = new Label();
lbl.Location = ctl.Location;
lbl.Text = ctl.Text;
myTabPage.Controls.Add(lbl);
}
else if (ctl is Button)
{
Button bttn = new Button();
bttn.Location = ctl.Location;
bttn.Text = ctl.Text;
myTabPage.Controls.Add(bttn);
}
}
tabControl1.TabPages.RemoveAt(0);
}

}
