Column Spanning

25 Feb 20228 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.

@Html.EJS().Grid("CellMerging").DataSource((IEnumerable<object>)ViewBag.Datasource).QueryCellInfo("QueryCellEvent").GridLines(Syncfusion.EJ2.Grids.GridLine.Both).Columns(col =>
{
    col.Field("EmployeeID").HeaderText("Employee ID").IsPrimaryKey(true).TextAlign(Syncfusion.EJ2.Grids.TextAlign.Right).Width("150").Add();
    col.Field("EmployeeName").HeaderText("Employee Name").Width("200").Add();
    col.Field("Time900").HeaderText("9.00 AM").Width("120").Add();
    col.Field("Time930").HeaderText("9.30 AM").Width("120").Add();
    col.Field("Time1000").HeaderText("10.00 AM").Width("120").Add();
    col.Field("Time1030").HeaderText("10.30 AM").Width("120").Add();
    col.Field("Time1100").HeaderText("11.00 AM").Width("120").Add();
    col.Field("Time1130").HeaderText("11.30 AM").Width("120").Add();
    col.Field("Time1200").HeaderText("12.00 PM").Width("120").Add();
    col.Field("Time1230").HeaderText("12.30 PM").Width("120").Add();
    col.Field("Time100").HeaderText("1.00 PM").Width("120").TextAlign(Syncfusion.EJ2.Grids.TextAlign.Center).Add();
    col.Field("Time200").HeaderText("2.00 PM").Width("120").Add();
    col.Field("Time230").HeaderText("2.30 PM").Width("120").Add();
    col.Field("Time300").HeaderText("3.00 PM").Width("120").Add();
    col.Field("Time330").HeaderText("3.30 PM").Width("120").Add();
    col.Field("Time400").HeaderText("4.00 PM").Width("120").Add();
    col.Field("Time430").HeaderText("4.30 PM").Width("120").Add();
    col.Field("Time500").HeaderText("5.00 PM").Width("120").Add();
}).Render()
