Thanks for using Syncfusion product.
By default, GridControl does not have the support to freeze the columns form left. But, you could achieve your reported scenario by adjusting two grids location and size. We have implemented the FrozenColum and provided the RightFrozenColCount property. Please refer the following code example and the sample,
FrozenColumn frozenColumn = new FrozenColumn();
frozenColumn.RightFrozenColCount = 3;
public void SetFrozenColumn()
this.grid.GridBounds = new Rectangle(this.grid.GridBounds.X,
this.grid.GridBounds.Width - (RightFrozenColCount * this.grid.DefaultColWidth),
this.FrozenColumnGrid.Location = new Point(this.grid.GridBounds.Width,0);
this.FrozenColumnGrid.Size = new Size((RightFrozenColCount * this.grid.DefaultColWidth), this.grid.ClientSize.Height);
Please let us know if you have any concerns.
