Form not closing in Form.Close() function

Question

Dear All,

 

I need your help to solve below issue:-

 

I have an issue when I am trying to close a windows form by calling form.close() function.

 

The scenario is mentioned below:-

 

I am using a mdi form. From menu I opened a child form. Then from child form(child), I opened another form(non -child)outside the container. in non child form I am using a database insert function. After insert, I am closing the non child form and I need to re open the child form in order to reflect the data saved from non child form.

 

in non child form , I wrote like this:-

 

frmMain mainObj = new frmMain();

Close();

mainObj.OpenAssetViewForm();

 

And in Main form , i wrote like this to open child form within container.

public void OpenAssetViewForm()
{
try
{
foreach (Form frmObj in Application.OpenForms)
{
if (frmObj.Name == "frmAssetRegView")
{
frmObj.Close();
if (frmObj == null)// is not changing into null
{
frmObj.Show();
}
break;
}
}
}
catch (Exception ex)
{
}
}
