Hi felix,
Thank you for using Syncfusion products.
One way you can do this by handling the CurrentCellChanged event of the GridControl and set the new value of the currentcell into selected cells. Below are the codes:
foreach (GridRangeInfo range in this.gridControl1.Selections.Ranges)
{
int k = range.Top;
int l = range.Bottom;
int m = range.Left;
int n = range.Right;
GridCurrentCell cc=this.gridControl1.CurrentCell;
for (int i = k; i <=l; i++)
{
for (int j = m; j <=n; j++)
{
this.gridControl1.Model[i, j].Text = cc.Renderer.ControlText;
}
}
}
Please refer to the below sample for implementation and let me know if this helps
