Hi,

I have the below requirement

There are two checkbox fields that are mutually exclusive and the user must select exactly one choice. In other words, clicking a non-selected checkbox field will deselect whatever other check box field was previously selected.

Any help greatly appriciated!

Thanks,

Srikanth Reddy

hi you need to write js,add a function on both the fileds.

register this one on field1 event and vice versa on field2
```
Xrm.Page.getAttribuet("filed2").setValue(false)

Xrm.Page.getAttribuet("filed1").setValue(true);
```

Hello Srikanth,

To implement it you can use OnChange event handler with following syntax:

For first field:

crmForm.all.<Second field here>.DataValue = !crmForm.all.<First field here>.DataValue;

For second field:

crmForm.all.<First field here>.DataValue = !crmForm.all.<Second field here>.DataValue;

the this is that this script would be triggered only when checkbox will loose focus.

Thanks for your response! I have tried in other way by attaching OnClick event to the checkbox field in OnLoad event of the form. It is working fine for me.
    crmForm.all.us_firstfield.onclick = function()
    {

        if (crmForm.all.us_secondfeld.DataValue==true)

        {

            crmForm.all.us_secondfeld.DataValue=false;

        }

    }

        }

    }





Unfortunately your code is not full. Following code will work without issues:
```
crmForm.all.us_firstfield.onclick = function()
{
	crmForm.all.us_secondfeld.DataValue = !crmForm.all.us_firstfield.DataValue;
}
```
