Hi Abhijit,
You can find the step to connect dashboards block in the link below fomr the documentation:
https://www.mathworks.com/help/releases/R2019b/simulink/slref/simulink.hmi.paramsourceinfo.html?browser=F1help
In there you will see that you need to work with a Simulink.HMI.ParamSourceInfo object. Here I copy the specific workflow:
Connect and Configure the Slider Block
Use a Simulink.HMI.ParamSourceInfo object and the set_param function to connect the Slider block to the Gain parameter of the Mu block. To connect a parameter, the Simulink.HMI.ParamSourceInfo needs to specify the block path for the block that corresponds to the parameter and the name of the parameter.
slider_param = Simulink.HMI.ParamSourceInfo;
slider_param.BlockPath = Simulink.BlockPath('vdp/Mu');
slider_param.ParamName = 'Gain';
set_param('vdp/Slider',"Binding",slider_param)
Configure the scale for the slider for a range of 1 to 10 with a tick mark spacing of 1.
slider_limits = [1 1 10];
set_param('vdp/Slider',"Limits",slider_limits)
To remove the connection, do:
set_param('vdp/Slider',"Binding",[])
Hope it can help you.

Hello,
Have you got a solution for R2018a release because the above command line leeds to the error :
MWDashboardBlock block (mask) does not have a parameter named 'Binding'
Thanks
