从GridView的从code得到评估和演示背后的价值

问题描述

我有一个GridView，从具有几个模板列的数据库负载。我如何检索code后面的评估和演示价值？换句话说，我所需要的模板字段名称该列。

我想获得注册，并将其存储在一个变量。

 ＆LT; ASP：的TemplateField的HeaderText =REGSORTEX pression =注册＆GT;
     ＆LT;＆EditItemTemplate的GT;
            ＆LT; ASP：复选框ID =cbRegEdit=服务器选中='＆LT;％＃（INT）的eval（注册）== 1％GT;' /＆GT;
     ＆LT; / EditItemTemplate中＆GT;
     ＆LT;＆ItemTemplate中GT;
                ＆LT; ASP：复选框ID =cbReg=服务器启用=false的选中='＆LT;％＃（INT）的eval（注册）== 1％GT;'＆GT;
                 ＆LT; / ASP：复选框＆GT;
      ＆LT; / ItemTemplate中＆GT;
      ＆LT; ItemStyle Horizo​​ntalAlign =中心/＆GT;
＆LT; / ASP：的TemplateField＆GT;
 

解决方案

您必须勾 OnRowDataBound 键，这样做：

 保护无效GridView1_RowDataBound（对象发件人，GridViewRowEventArgs E）
{  如果（e.Row.RowType == DataControlRowType.DataRow）
  {
    VAR注册=（（YourType）e.Row.DataItem）.Registrations;
    //做一点事
  }
}
 

您的GridView将不得不为：

 ＆LT; ASP：GridView的OnRowDataBound =GridView1_RowDataBound...
 

I have a gridview that loads from a database that has several TemplateFields. How do I retrieve the Eval value from code behind? In other words I need the template field name for that column.

I want to get "Registrations" and store it in a variable.

<asp:TemplateField HeaderText="REG" SortExpression="Registrations">
     <EditItemTemplate>
            <asp:CheckBox ID="cbRegEdit" runat="server" Checked='<%# (int)Eval("Registrations") == 1 %>' />
     </EditItemTemplate>
     <ItemTemplate>
                <asp:CheckBox ID="cbReg" runat="server" Enabled="false" Checked='<%# (int)Eval("Registrations") == 1 %>'>
                 </asp:CheckBox>
      </ItemTemplate>
      <ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>

解决方案

You have to hook to OnRowDataBound and do something like:

protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)
{

  if(e.Row.RowType == DataControlRowType.DataRow)
  {
    var registrations = ((YourType)e.Row.DataItem).Registrations;
    //do something 
  }
}

Your GridView would then have to be:

<asp:GridView OnRowDataBound="GridView1_RowDataBound" ...
