Note that my DG dataProvider is a xml of type I have tried to use the numericsort function but it does not sort correctly, also it stops working completely after first click on the header of creationData column. Can you please suggest.. Thanks, Hey Peter,

If anything like this is possible , it will solve my problem Thanks Giri Is it possible to write a common component for sorting which can be used by multiple datagrids , also keeping in mind columns can be numeric , alphanumeric & String Data type.

One small problem that I have found. In a practical situation you could have rows in your datagrid that do not have a date filled in. Idealy you would want these dates to appear first or last when you sort by your date collumn. However I have found that this solution as is does not take that into consideration. When you trace this out and look at both dates you will notice that if there is no value in the specific row you are looking at the date will show up as NaN. This of course is expected obviously you can not convert a null value to a date. If you keep tracing it out you will notice that depending on which way you are trying to sort accending or decending one of the two dates dateA, and dateB will always have a value. if dateA = NaN you want to return -1 if dateB = NaN you want to return 1 otherwise let this function do its job. So if you add the following lines to this function this is a perfect solution if(dateA.time.toString() == "NaN"){ return -1 }// end if else if(dateB.time.toString() == "NaN"){ return 1 }// end if obviosuly you will have to put the original return statement in the else case as follows else{ return ObjectUtil.dateCompare(dateA, dateB); }// end else Hope this helps Thanks again for this solution This is a great solutio.
