User Input for the Gain Block Using the dashboard elements

I would like to use the dashboard block (like the knob) to change the value in my gain block. How can this be done? Can I directly change the value within the gain block to match the value that is generated from the user input of the knob?

2. Double-click on knob block, block parameters dailog will open
3. Select the block whose parameter you want to control using knob, for eg. Gain block in your case
