如何通过回发保持我的运行时控件值? [英] how to keep my run-time controls value through post-back?

问题描述

我在运行时只有一个表头的表，当在这些控件中输入数据并单击保存单击事件代码(如
)时，会生成并向我的表添加控件行(dropdownlist-textbox-labels)

i have table with only table heads in run-time generate and add rows of controls (dropdownlist-textbox-labels) to my table when enter data in these controls and click save click event code like

for (int iRow = 1; iRow < Table1.Rows.Count; iRow++)
      {
          for (int iCol = 1; iCol <= 8; iCol++)
          {
              if (Table1.Rows[iRow].Cells[iCol].Controls.Count > 0)
              {
                  DropDownList odocType = (DropDownList)grid_Doc.Rows[iRow].Cells[iCol].Controls[0];
                  oImage.DocType =MainClass.GetInteger( odocType.SelectedValue);

              }
          }
      }

我发现Table1.Row = 1(th)，当我搜索这些问题时，我发现页面生命周期擦除了我在循环遍历表时在欠时创建的控件，但我没有找到所有行，并且控件中没有任何一个可以帮助我

i found Table1.Row =1 (th) when searched about these problem i found that page life cycle erase my controls created at runt-time when loop through my table i didn''t found all row and controls can any one help me plz

推荐答案

尝试使用Session，如ASP.NET会话状态概述 MSDN主题.

Try to use the Session, as described in the ASP.NET Session State Overview MSDN topic.

您需要使用以下一种状态管理技术来实现它:
MSDN:ASP.NET状态管理概述 [ ASP.NET中的状态管理-1 [ ASP.Net状态管理技术-2 [

You need to use one of the state management techniques to implement it:
