Scheduler with search parameter

Hello i have implemented scheduler in my application with custom event form it is working fine.

I gave the DataAction like this

Scheduler.DataAction = “Data.ashx”;
Scheduler.SaveAction = “Save.ashx”;

it is working fine at load time.

Now, i want to filter the data of scheduler using some filter(texbox, and dropdownlist) and bind the refreshed data with scheduler again.

So i am filtering data in my handler(Data.ashx) and calling bindscheduler(custom funtion- In which wrote all mandatory code of scheduler just for managing purpose) function again. But scheduler is showing only previous data not filtered one.

Can some one please how can i do this. I am attaching my handler file with it.
