18 Nov 20181 minute to read

You can change the orientation of the header text by using the customAttributes property.

Ensure the following steps:

Step 1:

Create a CSS class with orientation style for the treegrid header cell.

.orientationcss .e-headercelldiv {
    transform: rotate(90deg);
}

Step 2:

Add the custom CSS class to a particular column by using the customAttributes property.

    { field: 'taskName', headerText: 'Task Name', textAlign: 'Center', customAttributes: {class: 'orientationcss'}, width: 80 }

Step 3:

Resize the header cell height by using the following code.

function setHeaderHeight(args) {
    let textWidth: number = document.querySelector(".orientationcss > div").scrollWidth;//Obtain the width of the headerText content.
    let headerCell: NodeList = document.querySelectorAll(".e-headercell");
    for(let i: number = 0; i < headerCell.length; i++) {
        (<HTMLElement>headerCell.item(i)).style.height = textWidth + 'px'; //Assign the obtained textWidth as the height of the headerCell.
    }
}
