Question

每次点击更新链接按钮时，我都会连接gridSearchResults_RowUpdating事件。我想要做的是遍历事件rowindex中的行，并将行单元格中的文本框值添加到字符串集合中。我正在访问单元格中的文本框。如果这没有意义，我的代码应该有助于使事情更清楚。

        </Columns>
    </asp:GridView>

C＃

protected void gridSearchResults_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
        GridViewRow row = gridSearchResults.Rows[e.RowIndex];

        foreach (gridviewrow c in gridSearchResults.Rows[e.RowIndex])
        {

        }
}

所以有人知道循环遍历gridview行的单元格并抓取gridview行单元格中的文本框值的好方法。感谢

试试这个：

foreach (TableCell cell in gv.Rows(e.RowIndex).Cells) 
{
    TextBox txt1 = (TextBox)cell.FindControl("txtControlName");
    // or if you don't want to hard code the control name and assuming that there is only 1 control in the cell then use this:
    TextBox txt2 = (TextBox)cell.Controls(0);
}

gridview.row [e.rowindex]的foreach循环
