c# – 获取GridView列标题文本 – 始终返回空白

我有一个GridView,我想从列标题的文本.

for (int j = 0; j < grdToDisplay.HeaderRow.Cells.Count; j++)
{
    string s = grdToDisplay.HeaderRow.Cells[j].Text.ToString(); //Returns ""
    s = grdToDisplay.HeaderRow.Cells[j].Text; //Returns ""
    s = grdToDisplay.Rows[0].Cells[j].Text; //Returns text from first row of results not the header
   // s = grdToDisplay.Columns[j].HeaderText.ToString(); // does not work as column count is 0
}

GridView内容是在运行时根据用户查询生成的.标题可单击以进行排序.

如何循环GridView并列出列标题文本？

解决方法

你可以使用 GridViewColumn.HeaderText

for (int i = 0; i < grdToDisplay.Columns.Count; i++)
{
    string header = grdToDisplay.Columns[i].HeaderText;
}

编辑：

but this would give me no results as the columns count is 0

然后你有AutoGenerateColumns = true并且只计算声明性添加的列.因此,在对GridView进行数据绑定后使用此代码：

for (int i = 0; i < grdToDisplay.HeaderRow.Cells.Count; i++)
{
    string header = grdToDisplay.HeaderRow.Cells[i].Text;
}
