代码如下：
问题：除了这几个固定列能取到页眉的文本值 后面动态绑定的页眉值都为空 可是显示的时候确实显示了页眉 ，请高手赐教！
if (e.Row.RowType == DataControlRowType.Header)
{
for (int iColums = 0; iColums < dt.Rows.Count; iColums++)
{//循环在列表中要隐藏显示的列
strColums = dt.Rows[iColums][0].ToString();
for (int iCells = 0; iCells < e.Row.Cells.Count; iCells++)
{//循环当前绑定列表,从中找到与当前要隐藏的列名同名的表头列,将该cells置为false以达到隐藏显示列的目的
if (e.Row.Cells[iCells].Text == strColums)
{//这个地只有前面几个固定列能取到页眉的文本值 其余都为空 e.Row.Cells[iCells].Visible = false;
lInt.Add(iCells);
break;//找到后跳出内层循环继续循环要隐藏的下一列
}
}
}
}
