Hi,

You can override the similar style class(Mentioned below) as per your requirement.

.datagrid-grouppanel:after {

    -servicestudio-content: 'ⓘ You will be able to drag and drop columns in this container.';

    -servicestudio-font-size: 15px;

    -servicestudio-position: relative;

    -servicestudio-padding: 20px;

    -servicestudio-top: 25px;

}

Otherway around is you can refer the WijmoGroupPanelJS javascript file and overwrite accordingly.

HI Preeti,

You can use below Javascripts in Data Grid OnInitialize Event -

var div = document.querySelectorAll('[wj-part="div-ph"]');

div.innerHtml ="Drag and Drop columns here to create Groups.";

I hide it: 

var div = document.getElementsByClassName('datagrid-grouppanel')[0];

div.style.visibility = 'hidden';

You can follow this solution.
