Custom control renders table but doesn't resize at design time.

P: n/a
Hi all,

I have a control, that basically is my own version of the datagrid,
except that is renderers purely readonly tabular information.

When the control is rendered to the designer, I can click on the
control as rendered and move it, however I cannot resize it. I can
change the height and Width properties in the PropertyGrid and they
change, but the control doesn't resize.

When using the mouse to change the size, the control doesn't actually
resize, but the Width and Height properties do change. I can save the
changes, close the webform and open it again and it will display as I
had resized it. Here's a summary of what happens when I use the size
grips (the white boxes at each compass point that allow resizing with
the mouse). None of the these will change the size, some move the
control, some don't even affect the control - but all change the width
and height properties.

N: Moves the control up and down.
NW: Move the control in all directions.
W: Moves the control left and right
SW: Moves the control left and right.
S: No movement
SE: No movement
E: No movement
NE: Move the control up and down.

You can see for yourselves, below is the code for a simple control that
does the same:

Any ideas, it seems that the control is not resizing and re-rendering.
In WindowsForms you would capture the OnResize event and call

objTable.Height = MyBase.Height
