如何留住视图状态在GRIDVIEW创建的动态控件 [英] how to retain viewstate for the dynamic controls created in GRIDVIEW

问题描述

我在GridView控件创建动态文本框onRowCreated事件，但是当我尝试的FindControl我得到空

在这里是怎么了......董

 保护无效gvORg_RowCreated（对象发件人，GridViewRowEventArgs E）
{
   如果（（e.Row.RowState ==（DataControlRowState.Edit | DataControlRowState.Alternate））||（e.Row.RowState == DataControlRowState.Edit））
    {
      如果（e.Row.RowType == DataControlRowType.DataRow）
         {
              txBox txtReg =新的TextBox（）;
              txtReg.ID =_registration+ e.Row.RowIndex + rowId.ToString（）;
              txtReg.Text = reg.RegistrationToken;
              e.Row.Cells [7] .Controls.Add（txtReg）;
         }
    }
}
  保护无效gvOrg_RowUpdating（对象发件人，GridViewUpdateEventArgs E）
        {
            .....
            ....
             文本框_registration1 = gvOrg.Rows [e.RowIndex] .Cells [7] .FindControl（_登记+ e.RowIndex + ROWID）的文本框;
        }
