{
GridViewRow currentRow = gridView.Rows[rowIndex];
GridViewRow previousRow = gridView.Rows[rowIndex + 1];

for (int i = 0; i < currentRow.Cells.Count; i++)
{
if (currentRow.Cells[i].Text == previousRow.Cells[i].Text)
{
if (previousRow.Cells[i].RowSpan < 2)
currentRow.Cells[i].RowSpan = 2;
else
currentRow.Cells[i].RowSpan = previousRow.Cells[i].RowSpan + 1;
previousRow.Cells[i].Visible = false;

< Hope now you can merge all of your GridView Cells Or Columns in Row using ASP.NET C# within your project by writing a single line. Just call the clsUIUtility.GridView_Row_Merger method and send the GridView that you want to merge for all applicable Gridviews in your project.

There is a lot of scope to modify the generic method if GridView rows contain controls like DropDwonList, CheckBoxList, RadioButtonList etc. in a template column.
