Yep, I did the search. I have initialized canvas to each panel. But my problem is when i draw color to each canvas i lose the borders of the panel. It draws on everything. How can i keep the borders

Initializing the canvas to the panel does not draw on it, you can get the color of any pixel without changing the bitmap.

ah got it now ty very much . ,I was drawing color on the panel. that was hiding the borders !

I have one more question. If i execute panel2.color = colors.white
it also clears the borders altough they are set at designer. Why doesnt it just change the color of the panel but also clears the borders ?

I guess that the designer is doing a series of operations like draw a color rectangle in the border's color, then a smaller rectangle in the selected panel color etc.
When you draw it creates a new bitmap.

To change the color with border you must use this code:

Dim cdw As ColorDrawable
cdw.Initialize2(Color, Radius, BorderWidth, ColorBorder)
Panel.Background = cdw
