looking at the error, it is sure now that the exception is thrown from MDI can you place a debug breakpoint at following line in MDI form and look at the inner exception or stack track? RadMessageBox.Show(ex.Message + "
Dash Board: 051", "CollectPlus - Dashboard",

where is this code written? I suspect it is written somewhere on FrmBankAdvanceSearch backend only. If you are creating FrmBankAdvanceSearch again and again in it's form load event or somewhere you are using an endless/infinite loop, then this can happen. Debug the form load event for more, or post/attach form FrmBankAdvanceSearch code behind file.

Dear Nilesh, This error not occurring often, one time in a day. That is why I am unable to trace. Also one more information i giving you; this application running in about 10 computers, only one computer have this occurrence.

Dear Nilesh, Kindly go through my code below:- I created form object as property in MDI Window private FrmBankAdvanceSearch FrmAdvSrchObj { get; set; } then It is navigating to the form from main form private void MenuItemCurrentSrch_Click( object sender, EventArgs e) { try { if (FrmAdvSrchObj == null ) { FrmAdvSrchObj = new FrmBankAdvanceSearch(); FrmAdvSrchObj.FormClosing += frmAdvSrchObj_FormClosing; FrmAdvSrchObj.ShowDialog(); } } catch (Exception ex) { RadMessageBox.Show(ex.Message + "
Dash Board: 051" , "CollectPlus - Dashboard" , MessageBoxButtons.OK, RadMessageIcon.Error); } } In Form Constructor, I wrote like to this to set MessageBox theme public FrmBankAdvanceSearch() { InitializeComponent(); RadMessageBox.SetThemeName( "Windows7" ); } And In form load event, this is the code private void frmBankAdvanceSearch_Load( object sender, EventArgs e) { try { lblStaffID.Text = ClsGeneral.StrUserId; lblStaffName.Text = ClsGeneral.StrUserName; } catch (Exception ex) { RadMessageBox.Show(ex.Message + "
Active Search : 005" , "CollectPlus - Active Search" , MessageBoxButtons.OK, RadMessageIcon.Error); } }
