How many types of Form does your project have ? And where are any secondary Forms ... Forms which are NOT of Type MainForm ... created ?

We also don't know why -_-

But I think, you're getting the ActiveForm, so as soon as the Focus runs out, the value is null.

i got the answer
frmMain form1 = new frmMain();
foreach (Form mFrm in Application.OpenForms)
{
if (mFrm.Name == "")
{
form1 = (frmMain)mFrm;
form = form1;
}
}
form = form1;
