我会给你 3 个建议：
I will give you 3 suggestions:
问题是缺少resourceId，其次我在 xmlDataSource 变量上禁用了缓存，因为它始终显示相同的结果，但查询不同
现在问题是分页 - 在 MyWebParts:MyCustomWebPart 中您看到 PageSize，我将其设置为 1 但我看到 5 个项目我的清单 - 有什么问题吗？我的 XMLDataSource 是否有问题？
此外 - 是否可以将上面写入的内容（MyWebParts：MyCustomWebPart）转换为 .webpart 文件，以便可以在其他 pageLayouts 上重用..？
The problem was missing resourceId and secondly i disabled cache-ing on xmlDataSource variable because it showed always the same results but queries were different
Now problem is paging - in MyWebParts:MyCustomWebPart you see PageSize, I set it to 1 but I see 5 items on my list - whats wrong? Is my XMLDataSource wrong somehow?
Moreover - is it possible to convert what is written above (MyWebParts:MyCustomWebPart) to .webpart file so that it could be reusable on othere pageLayouts .. ?
我注意到您在初始 MyWebParts:MyCustomWebPart 中将 PageSize 设置为 10，并且在 SharePoint:SPDataSource 中您有一个条目
尝试将 SPDataSource 值设置为 1。

I have noticed that you have the PageSize set to 10 in the initial MyWebParts:MyCustomWebPart and in the SharePoint:SPDataSource you have an entry
<asp:Parameter DefaultValue="10" Name="MaximumRows"/>Try setting the SPDataSource value to 1.
