Column Spanning in ASP.NET Core Grid Component
16 Feb 202416 minutes to read
The grid has option to span the adjacent cells. You need to define the colSpan attribute to span cells in the queryCellInfo event.
In the following demo, employee Davolio is doing testing from 9.00 A.M. to 10.00 A.M. so that the cells have been spanned.
<ejs-grid id="Grid" dataSource="@ViewBag.DataSource" queryCellInfo="QueryCellEvent" gridLines="Both" allowPaging="true">
<e-grid-columns>
<e-grid-column field="EmployeeID" headerText="Employee ID" isPrimaryKey="true" textAlign="Right" width="150"></e-grid-column>
