Child usercontrol contained parent user control does'nt redisplay

[lotus]

HI All..
I'm realtively new to C#.

I have MainForm which includes Parent usercontol, and this parent
usercontrol also contains child usercontrol.

MainForm --> Parent usercontrol --> child usercontrol

Parent usercontol has one button to change the child usercontorl's
variable.
Child usercontrol has one textbox that display child usercontrol's
variable.

When I press button of parent usercontrol, I change the variabe of
child user control, and I want to display the variable to textbox.
But textbox does not change its value.

What kind of action do I need?
Any suggestion would be greatly appreciated.

Hi lotus,
in your set_val method you are assigning the new value to a variable, but
you are not updating the value of the Text property of the textbox which
controls what is displayed in the textbox, you just need to add one more line:

public partial class ChildUC : UserControl
{
double val1=0;

public ChildUC()
{
InitializeCompo nent();
this.textBox1.T ext = val1.ToString() ;
}
public void set_val(double i)
{
val1 = i;
this.textBox1.T ext = val1.ToString() ;
}
}
Hope that helps
