各位大侠！帮忙看下这个问题（GridView动态添加列，刷新(回发),模板列的控件丢失）
在CSDN看到这样一篇：http://bbs.csdn.net/topics/320247030
介绍在OnInit中动态添加列,模板列的控件不会丢失
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
}
但是我的需求是要根据页面控件的值动态创建GridView。可是在OnInit中无法获取页面控件的值
如：
一个gridview初始有固定的模板列用来勾选
<asp:GridView ID="gridView" runat="server" AutoGenerateColumns="False" ShowHeader="True"
Width="100%">
<Columns>
<asp:TemplateField>
<HeaderTemplate>
<input type='checkbox' id='chkAllSelect' name='chkAllSelect' onclick="CheckAll(this)"
runat="server" />
</HeaderTemplate>
<ItemTemplate>
<input type="checkbox" id="chkSelect" name="chkSelect" runat="server" value='<%# Eval("Did")%> ' />
</ItemTemplate>
<ItemStyle Width="20px" />
</asp:TemplateField>
</Columns>
</asp:GridView>
//创建列的方法
public void CreateGridView(GridView dataview, int year, int month)
{
int i;
int CurMonthDay = DateTime.DaysInMonth(year, month);
int count = dataview.Columns.Count;
for (i = 1; i < count; i++)
{
dataview.Columns.RemoveAt(1);//再次查询时删除所有日期列，重新加载日期列，重一开始是为了保存勾选列
}
for (i = 0; i < CurMonthDay; i++)
{
int day;
DateTime tm = new DateTime(year, month, i + 1);
ImageField newcoltp = new ImageField();
switch (tm.DayOfWeek)
{
case DayOfWeek.Sunday:
day = i + 1;
newcoltp.HeaderText = day.ToString() + "\n日";
break;
case DayOfWeek.Monday:
day = i + 1;
newcoltp.HeaderText = day.ToString() + "\n一";
break;
case DayOfWeek.Tuesday:
day = i + 1;
newcoltp.HeaderText = day.ToString() + "\n二";
break;
case DayOfWeek.Wednesday:
day = i + 1;
newcoltp.HeaderText = day.ToString() + "\n三";
break;
case DayOfWeek.Thursday:
day = i + 1;
newcoltp.HeaderText = day.ToString() + "\n四";
break;
case DayOfWeek.Friday:
day = i + 1;
newcoltp.HeaderText = day.ToString() + "\n五";
break;
case DayOfWeek.Saturday:
newcoltp.HeaderText = ((i + 1)).ToString() + "\n六";
break;
}
newcoltp.ItemStyle.Width = 20;
newcoltp.DataImageUrlField = string.Format("DDay{0}", i + 1);
dataview.Columns.Add(newcoltp);
}
}
