About controls:

For beginners, it is generally necessary to first know the general role of the various controls, for beginners, quickly grasp some of the most common functions to meet the control is very important, when familiar with the grasp, it is necessary to consider from different solutions to choose the best solution to achieve.

If in the learning process, to use a specific function and will not be used, be good at the following four aspects to solve.

1. Through the system comes with the API help manual to see, because this is written in English, it is difficult to read, English good can see more
2. Look at the control event with the system's own global search function, and then go to the examples that others have used before, which is easy to read and more suitable for beginners to learn. For the use of code can be used on their own, if you feel that writing is not too good, you can also follow their own rules to rewrite.
3. Can find some of the former colleagues summed up this knowledge, through their own research, summed up, to transform it into their own things,
4. Ask, is to have experienced colleague asked, asked after to be good at summing up, so that can be converted into their own things.
5. Online search, this is not very useful for lims systems, but because the system is based on the. NET platform, some controls and Microsoft IDE (Visual Studio) are relatively close, you can go online to find something relevant to facilitate their understanding of learning.

The above four is not just for the control of learning, for learning some other knowledge is also more appropriate.

Today, there is a problem with the Onupdatingcell event in the DataGrid, which is the event that is triggered when the value of a row in the DataGrid changes, but if the line you set is changed in an indirect way (for example, by using UD to pop a window), Will not trigger this Onupdatingcell event, this time it is necessary to re-write the UD popup function, get the value before and after the change, when the values change, write code to implement the function to add

When implementing certain functions, it is necessary to first figure out the specific steps to implement the function, and take a few steps to understand what the conditions are for each step and have a clear idea.

At the time of implementation, if there is ready-made code, it can be called directly, if there is no ready-made code, there are similar good code, you can put "he" to make appropriate changes. , but also familiar with the good code
