In the past I’ve had success by making separate text boxes above the data grid in order to achieve this. Perhaps you could try that?
Hi Poorna Sandeep,
you could try to add styling to the grid header.
This is my file before editing.
This is my file after editing. I just added a new line at the end nothing else but still, it is showing an error. Please let me know to change the contents of it?
Sorry i can’t add images in the comment, so keeping it as a new answer.
To solve your issue you need to look into your stylesheet (CSS).
You would have to create a custom class (ex .sticky-header) for the datagrid header with a ‘position : sticky; ‘ in css code.
I have a link for you that will show you what I mean: http://jsfiddle.net/TylerH/gv9ugaw9/
If you’re unfamiliar with CSS you might want to look here: https://www.w3schools.com/css/
Based on above screenshot (and below comment).
You need to compile your SCSS, you could use Calypso for this here: https://docs.mendix.com/howto8/front-end/calypso
