嗨
我有一个gridview，并且其中有一个包含很多控件的模板.除lblQty我尝试过的所有内容外，所有标签均显示正确的值，但它仅显示0，在某些情况下不是正确的值.这是Gridview的示例代码

推荐答案

从您提供的内容来看，这是我现在能给您的最好的答案.

1)您需要在收集数据的地方调试代码，并确保数据中的字段值开头正确.
2)确保您的值< code> propProdQ​​ty</code>的拼写正确.正确地用正确的大小写拼写，并且在前面也没有错.

From what you have provided, this is about the best I can give you right now.

1) You need to debug your code behind where you collect the data and ensure that the field value in the data is correct to start with.
2) Ensure that the spelling of your value <code>propProdQty</code> is spelled correctly with correct casing and that nothing is wrong on that front either.
