//显示合计
int inCount = gdvIn.Rows.Count - 1;
int outCount = gdvOut.Rows.Count - 1;
for (int i = 1; i < gdvIn.Columns.Count;i++ )
{
Label lblIn = (Label)gdvIn.Rows[inCount].FindControl("Label"+i.ToString());
Label lblOut = (Label)gdvOut.Rows[outCount].FindControl("Label" + i.ToString());
Label lblSum = (Label)Page.FindControl("sum"+i.ToString());
decimal sum = decimal.Parse(lblIn.Text) - decimal.Parse(lblOut.Text);
lblSum.Text = sum.ToString("F2");
if(sum<0)
{
lblSum.ForeColor = System.Drawing.Color.Red;
}问题是：1-11月都是收入小计和支出小计都是正确的，但12月不显示各自合计这是错误呢？思维定势了，求大侠们指点迷津。

gdvIn.Columns.Count=12的话，循环需要改为
for (int i = 1; i <= gdvIn.Columns.Count;i++ )

如果datatable里面数据是正确的，那就是绑定的问题，否则就是数据问题

对的 ，Columns.Count其实是12，12个月就12列嘛[/quote]
不会吧，如果是12 应该是11才对吧，还是我看花眼了[/quote]
Label i 从Label1,Label2......Label12 都执行了，我设置断点调试看到是到12的

为了方便点看，我去了对应绑定的字段切换到视图

for 循环的列数对不对？
for (int i = 1; i < gdvIn.Columns.Count;i++ ) 循环了几次 ?
