GridView PreRender Event and Example--gridview + checkbox, click multiple columns (check delete)before there is an example, the same results can be used in two ways to practice[GridView] data binding expression? Or a RowDataBound event?I think this teaching method is very good, "the same topic, there are many solutions "(as the Bruce Lee picture below says, "proficiency" is important)Students respond more warmly, can also choose their own habits, thei

Sometimes the gridview and datapager are used together with the bound database to finally read the database data, and the 'homepage-Previous Page-Next page-last page 'is displayed, however, when you click the buttons 'homepage-Previous Page-Next page-last page', you always need to click twice. In fact, the solution is very simple. You only need to bind the database once in the prerender event of the gridview. Because the page first executes page_load

Init, load, and prerender event execution sequence: Init, load, and prerender event execution sequence:1) Init event of the control 2) Init event on the page where the control is located 3) Load events on the page where the control is located 4) Load events of controls 5) prerender event on the page where the control is located 6) control

If I first write a front-end template and then convert it into the syntax of the Ejs template, I need to decide which angular syntax needs t

datagrid| Page | solve | The problem DataGrid If you use pagination, the last page may not be "full page" so that the layout of the DataGrid may be problematic, the remaining rows are too wide, and the entire DataGrid becomes ugly. The solution can probably be considered from three places: 1. Fill in the new data line in the DataSource. 2, fill in the DataGrid with the new blank control row. 3. Fill in the new HTML control line with JavaScript in webpage. I used the second method, in the respo

Issues in the previous section:Co-process: switch on IO operation.But when do you cut it back? How do I know I'm done with IO?first, the event-driven model introductionTypically, when we write a program that server processes a model, there are several models: (1) Each time a request is received, a new process is created to process the request;(2) Each time a request is received, a new thread is cre

, nonblocking I/O, and I/O multiplexing models are synchronous I/O models, because in the process of waiting for the data, the processes in these three models do not do anything else, even if the non-blocking polling can be considered as a synchronization. The book also argues that the signal-driven I/O model is synchronous I/O, which says that POSIX defines the synchronous IO operation as "causing the request process to block until I/O operation is c

Background: Pio DMA interrupt polling The speed of early I/O devices is not too high compared with that of CPU. The CPU periodically polls the IO Device once to see if there are any processing requirements. If yes, it will be processed and then return to continue working. So far, the floppy disk still keeps this round robin method.With the rapid increase in CPU performance, this inefficient way of working wastes a lot of CPU time. As a result, interru

For example, in some device interrupt status registers, the registers are autom

I. I/O portA port is the address of a register in an interface circuit that can be accessed directly by the CPU. Almost every peripheral is made from a register on a read-write device. The CPU sends commands to the registers in the interface circuit through these addresses, namely ports, to read the status and transmit the data. Peripheral registers, also known as "I/O ports", typically include: control registers, status registers, and data registers, and the registers of a peripheral are usuall
