Retrieve control value from parent form from a user control

Question

Hi,

 

I have a user control on a parent form. The parent form has a RadioButton. I need to be able to determine the checked state of the RadioButton from the user control.

 

I tried creating a public property on the parent form with the following code:

 

public bool IsDemarcateMode

{

get { return rdoDemarcate.Checked; }

}

 

However, it does not work because the property is not visible from the user control at run time, using the following line of code:

 

bool bChecked = this.Parent.IsDemarcateMode;

 

Any suggestions?

 

Thanks.

Dan

Answer 1

You need to cast the "this.Parent" to your parent form in order to get that property from your parent form.

Answer 2

That did it!  Thanks. The exact syntax was not immediately obvious, but here is what worked:

 

frmMain frm = (frmMain)this.Parent;

bool bChecked = frm.IsDemarcateMode;
