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.

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 + "\nDash Board: 051", "CollectPlus - Dashboard",

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 + "\nDash 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 + "\nActive Search : 005", "CollectPlus - Active Search", MessageBoxButtons.OK, RadMessageIcon.Error);
}
}

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.
