Control is not found in FlowLayoutPanel

Question

I have many group Boxes in a flow layout panel all are generated programmaticaly. when I try to find any specific groupbox at run time nothing comes out. Here is my code, Please help.

    foreach (Control ctr in flowLayoutPanel1.Controls)
    {
        if (ctr.Name=="BSE")
        {
            MessageBox.Show("Control is found");                     
        }                
    }

Code, which creates controls:

var Allzone = (from a in db.Zones select a.name).ToList();
foreach (var z in Allzone)
{ 
    GroupBox g = new GroupBox(); 
    g.Text = z; 
    g.Name = z; 
    g.Tag = z; 
    g.Font = new Font("Verdana", 8,FontStyle.Bold); 
    g.ForeColor = Color.White; 
    g.Width = 49; 
    g.Height = 90; 
    flowLayoutPanel1.Controls.Add(g); 
}

Show the code that creates the controls and assigns them to `flowLayoutPanel1`. — DonBoitnott, Jun 12 '13 at 14:07

AllZone contain the name of all zone But this is not a problem Because All Control generated perfectly! the only problem i m facing is how to find a control in flow panel — Umar Abbas, Jun 12 '13 at 14:23
C# is case-sensitive, so if the name you assigned was `bse` and you test for `BSE` that will not equate. — DonBoitnott, Jun 12 '13 at 14:25
"i also try this nothing happens" if (ctr.Name.ToUpper() == "BSE".ToUpper()) — Umar Abbas, Jun 12 '13 at 14:30
I just setup a test that works. In place of `Allzone` I used a `String[]` (since I don't know what yours _really_ is). Otherwise, my code is identical to yours. I suspect there is more going on here, or `Allzones` is not simply a collection of `String` objects. — DonBoitnott, Jun 12 '13 at 14:38
I got it just add trim() in control name..Now the working Code is foreach (Control ctr in flowLayoutPanel1.Controls) { if (ctr.Name.Trim()=="BSE") { MessageBox.Show("Control is found"); } } this Trim() Ruined my all day.Thanks DonBotinott — Umar Abbas, Jun 12 '13 at 14:42
Do the Trim() and ToUpper() when you set the Name property: `g.Name = z.Trim().ToUpper();` Then your check should behave better without needing all the extra stuff... — Idle_Mind, Jun 12 '13 at 15:06

I got it just add trim() in control name.

Now the working Code is

 foreach (Control ctr in flowLayoutPanel1.Controls) 
{ 

if (ctr.Name.Trim()=="BSE") 

   {
     MessageBox.Show("Control is found");
   } 
}

this Trim() Ruined my all day. Thanks DonBotinott
