｝

解决方案 »

  1.   


    DropDownList text 绑定 stuname
    value 绑定 stuid
      

  2.   

    那 GridView 想绑定什么
      

  3.   

    <asp:TemplateField HeaderText=""> 
                              <EditItemTemplate> 
                                  <asp:DropDownList ID="ddl" runat="server" TabIndex="-1" CssClass="not-null" Width="200px" AutoPostBack="True" OnSelectedIndexChanged="ddl_SelectedIndexChanged" > 
                                  </asp:DropDownList> 
                              </EditItemTemplate>                          
                              <ItemTemplate> 
                              </ItemTemplate> 
                              <ItemStyle Width="250px" CssClass="GVCellStyle" /> 
                              <HeaderStyle Width="250px" /> 
                          </asp:TemplateField> 
        protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e) 
        { 
            if (e.Row.RowState == DataControlRowState.Edit || e.Row.RowState == (DataControlRowState.Alternate | DataControlRowState.Edit)) 
            { 
                DropDownList ddl = (DropDownList)e.Row.FindControl("ddl"); 
                if (ddl != null) 
                { 
              //绑定数据 
                } 
            } 
        } 
      

  4.   

    百度 也专业点if (e.Row.RowState == DataControlRowState.Edit || e.Row.RowState == (DataControlRowState.Alternate | DataControlRowState.Edit)) 
      

  5.   

    <asp:TemplateField HeaderText=""> 
                              <EditItemTemplate> 
                                  <asp:DropDownList ID="ddl" runat="server" TabIndex="-1" CssClass="not-null" Width="200px" AutoPostBack="True" OnSelectedIndexChanged="ddl_SelectedIndexChanged" > 
                                  </asp:DropDownList> 
                              </EditItemTemplate>                          
                              <ItemTemplate> 
                              </ItemTemplate> 
                              <ItemStyle Width="250px" CssClass="GVCellStyle" /> 
                              <HeaderStyle Width="250px" /> 
                          </asp:TemplateField> 
        protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e) 
        { 
            if (e.Row.RowState == DataControlRowState.Edit || e.Row.RowState == (DataControlRowState.Alternate | DataControlRowState.Edit)) 
            { 
                DropDownList ddl = (DropDownList)e.Row.FindControl("ddl"); 
                if (ddl != null) 
                { 
              //绑定数据 
                } 
            } 
        }

    要闪人了，写个简单的DEMO
      

  7.   

    gv.DataSource=newstring[] {"","","" };
     这个是什么意思 为什么要3个""
      

  8.   

    gv.DataSource=newstring[] {"","","" }; 
    这个是什么意思 为什么要3个"" 随便绑定的， 为了查看效果
      

  9.   

    DataControlRowState.Edit没有环境就写的，就写这个？
