写了一个合并GridView控件单元格的方法，比较好用。不用修改代码，拷贝后直接就可以使用。
/// <summary>
/// 合并单元格方法
/// </summary>
/// <param name="iColumns">第几列数据相同</param>
private void MergeGridCell(int iColumns)
{
//合并的行数
int row;
//GridView行数
int col;
//从第几行开始合并
int count;
row = 0;
count = 0;
for (col = 1; col < this.GridView1.Rows.Count; col++)
{
if (GridView1.Rows[col - 1].Cells[iColumns].Text == GridView1.Rows[col].Cells[iColumns].Text)
{
row = row + 1;
GridView1.Rows[col].Cells[iColumns].Visible = false;
if (col == GridView1.Rows.Count - 1)
{
row = row + 1;
GridView1.Rows[count].Cells[iColumns].RowSpan = row;
count = 0;
}
}
else
{
GridView1.Rows[count].Cells[iColumns].RowSpan = row + 1;
row = 0;
count = col;
}
}
}
如果需要合并的列是模板列，就使用下面的方法。
//ControlID:模板列控件的ID
private void MergeGridTemplateCell(int iColumns,string ControlID) {
int row ;
int col ;
int count;
row = 0;
count = 0;
for (col = 1; col < this.GridView1.Rows.Count; col++)
{
if (((Literal)GridView1.Rows[col - 1].Cells[iColumns].FindControl(ControlID)).Text == ((Literal)GridView1.Rows[col].Cells[iColumns].FindControl(ControlID)).Text)//"litDay"
{
row = row + 1;
GridView1.Rows[col].Cells[iColumns].Visible = false;
if (col == GridView1.Rows.Count - 1)
{
row = row + 1;
GridView1.Rows[count].Cells[iColumns].RowSpan = row;
count = 0;
}
}
else
{
GridView1.Rows[count].Cells[iColumns].RowSpan = row + 1;
row = 0;
count = col;
}
}
}
调用方法：
this.MergeGridCell(2);
this.MergeGridTemplateCell(3, "lblDay");
合并后的效果：
