You will have to use RowSpan.
您将不得不使用RowSpan.
Refer following code for it:
请参考以下代码：
protected void GridView1_DataBound1(object sender, EventArgs e)
{
for (int rowIndex = GridView1.Rows.Count - 2;
rowIndex >= 0; rowIndex--)
{
GridViewRow gvRow = GridView1.Rows[rowIndex];
GridViewRow gvPreviousRow = GridView1.Rows[rowIndex + 1];
for (int cellCount = 0; cellCount < gvRow.Cells.Count;
cellCount++)
{
if (gvRow.Cells[cellCount].Text ==
gvPreviousRow.Cells[cellCount].Text)
{
if (gvPreviousRow.Cells[cellCount].RowSpan < 2)
{
gvRow.Cells[cellCount].RowSpan = 2;
}
else
{
gvRow.Cells[cellCount].RowSpan =
gvPreviousRow.Cells[cellCount].RowSpan + 1;
}
gvPreviousRow.Cells[cellCount].Visible = false;
}
}
}

Simplest way to merge Row-cells of first column is as below. Please note that For Loop is always to be iterated in reverse.
合并第一列的行单元格的最简单方法如下。请注意，For 循环总是要反向迭代。
protected void GridView1_DataBound(object sender, EventArgs e)
{
int RowSpan = 2;
for (int i = GridView1.Rows.Count-2; i >=0 ;i-- )
{
GridViewRow currRow = GridView1.Rows[i];
GridViewRow prevRow = GridView1.Rows[i+1];
if (currRow.Cells[0].Text == prevRow.Cells[0].Text)
{
currRow.Cells[0].RowSpan = RowSpan;
prevRow.Cells[0].Visible = false;
RowSpan += 1;
}
else
RowSpan = 2;
}
}
If you want to merge row-cells of all columns similarly, you can use another "forloop" within outer forloop written above
如果你想合并所有列的行单元格，你可以在上面写的外部 forloop 中使用另一个“forloop”
