我需要在网格视图中显示数据,并为某些列合并行。请帮我准备以下定义格式的网格视图:
原始数据来自数据库,格式如下:
请帮助我找到动态有效地完成此任务的最佳方法。

您必须使用RowSpan
。
请参阅以下代码:
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;
}
}
}

合并第一列的行单元的最简单方法如下。请注意,For Loop总是反向迭代。
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;
}
}
如果你想类似地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”
