 <   header   style     font-size   =  9pt    horizo​​ntalalign   = 中心    /  >  
 <   item   style     horizo​​ntalalign   =  左    /  < span class =code-keyword>>  
 <   / ItemTemplate  >  
 <   / asp：TemplateField  >  
 <   / asp： GridView  >  
 <   / ContentTemplate  >  
 <   / ajaxToolkit：Accordion  >  
 
 <   / asp：Content  >  

我尝试了什么：



gridview1没有在aspx.cs页面中显示

解决方案

因为gridview是手风琴里面你不能直接访问gridview。



您需要做的是访问手风琴控件和手风琴控件的控件集合中，您可以使用find从集合中获取gridview方法

                                            <headerstyle font-size="9pt" horizontalalign="Center" />
                                            <itemstyle horizontalalign="Left" />
                                        </ItemTemplate>
                                    </asp:TemplateField>
            </asp:GridView>
        </ContentTemplate>
    </ajaxToolkit:Accordion>

</asp:Content>

What I have tried:

gridview1 not showing in aspx.cs page

解决方案

Because gridview is inside accordion you cannot access the gridview directly.

What you have to do is access the accordion control and in the controls collections of accordion control you can get the gridview from the collection by using find method
