Datagrid fontsize

How do i set the fontsize of the title and datacells in a radzen datagrid ?

The DataGrid doesn’t expose a parameter for font size directly, so you set it with CSS. Give the grid a CSS class and scope your rules to it so you don’t affect other grids on the page:

...

/* Column titles (header) */
.my-grid .rz-column-title-content {
font-size: 16px;
}

/* Data cells */
.my-grid .rz-cell-data {
font-size: 14px;
}
