GridView error Summary

Today, I finally solved the problem that bothered me for a few days. In the gridview, I don't know why pager does not appear. Only one function can be checked. The rowdatabound problem was found at last.

I still did not find any reason. One statement was blocked by one statement, and this function contains one statement:

E. Row. Cell [0]. Visible = false;

This statement is directly written in the first line and is not processed separately through the type of datarow. The consequence is that, as the pager of the last row, it is located in cell [0] and directly hide. Omg!

It was just a small problem, and it took me a long time to check it. It is necessary to form a very rigorous programming style, or else this situation may occur at any time. I can only say that software is a meticulous task!
