DNTMLxGrid checkbox values in a cell

Hi,
In a column, I am showing check boxes. I want the value of column to be other than true or false. I want to set these values from xml.

Regards,
Ashutosh Agarwal

Such functionality is not available, checkbox columns has hardcoded  0 and 1 as values for checked and unchecked states, the only way to change behavior - customization of js code.
If necessary I can provide additional info where customization need to be done ( there is no ready to use solution )

Yes please provide additional info where customization need to be done.

                                this.setValue("0") //need to be updated with necessary unchecked value
                            else
                                this.setValue("1")  //need to be updated with necessary checked value

                        if (val){
                            val=val.toString()._dhx_trim();
                            if ((val=="false")||(val=="0")) val="";
                            }
                        if(val){  //need to be updated with correct rule
                            val = "1";
                            this.cell.chstate = "1";//need to be updated with necessary checked value
                        }else{
                            val = "0";
                            this.cell.chstate = "0"//need to be updated with necessary unchecked value

You can replace mentioned places with another hardcoded value, or with some js vars which will be set separatly
