Windows forms show and showdialog working differently displaying datagridview

[tshad]

I previously had a form that called another form that had a datagridview on it. I passed a DataTable to the child form and on the childform it bound it.

Parent calls child form and shows it.
TableInfoti = new TableInfo();
t1.Show();

Parent passes Datatable:
t1.ShowDataGrid(dt);

Child binds it to datagrid:
public void showDataGrid(DataTable dt, string type)
{
dgvTableColumns.DataSource = dt;
}

This works perfect.
But now I want to make this a modal form, so I change the t1.Show() to t1.ShowDialog() or t1.ShowDialog(this)

Now the grid is showing nothing on the Child form.

But if I change the code to do the ShowDialog after I call ShowGridView(), it works fine.

TableInfoti = new TableInfo();
t1.ShowDataGrid(dt);
t1.ShowDialog();

Why is the behavior different?

Thanks,

Tom

Are you converting this to ASP.NET?

If not, I think you meant to post it in this forum: forum796

I thought win forms was also part of asp.net.

We have both windows forms and Web forms.

And I am not using VB.net. I am using C#.

No, ASP.NET is a webform technology and is very different from winforms
