gridview跨行跨列

  

int row = 0;
int index = 1;
string currentExam_Uid = "";
string oldExam_Uid = "";
protected void gvList_RowDataBound(object sender, GridViewRowEventArgs e)
{
int rowindex = e.Row.RowIndex;
if (e.Row.RowType== DataControlRowType.DataRow)
{
if (rowindex==0)
{
currentExam_Uid = ((HiddenField)e.Row.FindControl("hidExamUid")).Value;
return;
}
currentExam_Uid = ((HiddenField)e.Row.FindControl("hidExamUid")).Value;
oldExam_Uid = ((HiddenField)gvList.Rows[rowindex - 1].FindControl("hidExamUid")).Value;
if (currentExam_Uid == oldExam_Uid)
{
((Literal)gvList.Rows[row].Cells[0].FindControl("lblNum")).Text = index.ToString(); //序号
if (gvList.Rows[row].Cells[0].RowSpan == 0) gvList.Rows[row].Cells[0].RowSpan++;
if (gvList.Rows[row].Cells[1].RowSpan == 0) gvList.Rows[row].Cells[1].RowSpan++;
gvList.Rows[row].Cells[0].RowSpan++;
gvList.Rows[row].Cells[1].RowSpan++;
e.Row.Cells[0].Visible = false;
e.Row.Cells[1].Visible = false;
}
else
{
index++;
row = rowindex;
if (((Literal)e.Row.Cells[0].FindControl("lblNum")).Text == "")
{
((Literal)e.Row.Cells[0].FindControl("lblNum")).Text = index.ToString();
}
}
}

 

 

以前写过。还可以优化。不论是写在OnRowDataBound中还是OnDataBound里都能做分组合并。存下。
