Hello,
I'm new to Rad controls and i'm having a problem accessing the parent radfrom of a child on (MDI not enabled). would appreciate the assistance.

in the parent form when i click a button it does this:

frmAddExtraItem fax = new frmAddExtraItem();

fax.Show(this);

and it shows the child form, but when i click a button in the child form the code is this:

((MainForm)this.ParentForm).dataGridView1.Rows.Add(insertitem.EDescription);


now datagridview1 is public, but this.ParentForm is always null, i tried all combinations possible for both code snippets, trying this.Parent, and even this.Parent.Parent multiple times, and also in the first code i tried fax.ParentForm = this, fax.Parent = this, and fax.Parent = this.Parent, and so on many combinations including fax.ShowDialog(), but nothing seems to work and i always get this.Parent or this.ParentForm as null, how can i access the dtatagridview1 in the parent in that case?

thank you

Hi Mohamed,

Your question has already been answered in the other thread you've opened. 

I am adding the answer here in order the community to benefit from it:

You can use the Owner property to get the corresponding grid:
private void radButton1_Click(object sender, EventArgs e)
{
    RadGridView grid = ((Form1)this.Owner).RadGridView1;
    grid.Rows.AddNew();
}

I hope this helps.
