Hi Riccardo,
Thanks for using Syncfusion products.
We have provided different style settings for CurrentCell apart from Selection. So, the selected cell is rendered differently than other selected cells. To have same back color for the cells in the selected row, CurrentCellStyleInfo.BackColor can be changed to SelectionStyleInfo.BackColor property. Please refer to the below code example,
Code Snippet:
// Initializes the Selection BackColor as CurrentCell's BackColor.
this.sfDataGrid.Style.CurrentCellStyle.BackColor = this.sfDataGrid.Style.SelectionStyle.BackColor;
