ASP.net的AJAX

The .Net framework training in these two days has given me a better understanding of Microsoft stuff. In the past, I just thought that MS things were just dragged here and there, and there were no other more surprising features. After introducing ASP AJAX ToolKit today, it was really surprising.

To give some simple examples, for example, if you want to add such an effect, after entering two numbers into a Textbox, you need to have an association function to list all databases or web services starting with these two numbers. Just one sentence is enough in ASP.NET.

ID="AutoCompleteExtender1"
TargetControlID="ZipCode"
ServicePath="ZipCodeService.asmx"
ServiceMethod="GetMatchingZipCodes"
MinimumPrefixLength="2"
CompletionListElementID="ctl 00_MainPlaceHolder_ZipCodeComp
letionList"
CompletionSetCount= "15"runat="server"/>

It's too simple. It would be much more troublesome to do it in j2ee. However, with the AJAX framework built on J2EE such as DWR, it is much easier to do it.

For another example, a ZipCode should prompt you to enter 5 numbers. First, filter to keep only numbers and -. Another sentence, the phone number should also be like this:

ID="FilterTextBoxExtender1"
TargetControlID="ZipCode"FilterType="Custom"
ValidChars="0123456789-"
runat="server"/> ;

ID="FilterTextBoxExtender2"
TargetControlID="Phone"FilterType="Custom"
ValidChars="0123456789()-."
runat="server"/>

Then prompt to enter 5 Numbers

ID="TextBoxWatermarkExtender1"
TargetControlID="ZipCode"WatermarkText="xxxxx"
runat="server"/>

ID="TextBoxWa termarkExtender2"
TargetControlID ="Phone"WatermarkText="xxx-xxx-xxxx"
runat="server"/>

The displayed effect is like this

The core concepts of .NET asynchronous programming, LINQ and EFCore are: 1. Asynchronous programming improves application responsiveness through async and await; 2. LINQ simplifies data query through unified syntax; 3. EFCore simplifies database operations through ORM.

How to use various symbols in C language How to use various symbols in C language Apr 03, 2025 pm 04:48 PM

The usage methods of symbols in C language cover arithmetic, assignment, conditions, logic, bit operators, etc. Arithmetic operators are used for basic mathematical operations, assignment operators are used for assignment and addition, subtraction, multiplication and division assignment, condition operators are used for different operations according to conditions, logical operators are used for logical operations, bit operators are used for bit-level operations, and special constants are used to represent null pointers, end-of-file markers, and non-numeric values.

How to use char array in C language How to use char array in C language Apr 03, 2025 pm 03:24 PM

The char array stores character sequences in C language and is declared as char array_name[size]. The access element is passed through the subscript operator, and the element ends with the null terminator '\0', which represents the end point of the string. The C language provides a variety of string manipulation functions, such as strlen(), strcpy(), strcat() and strcmp().

What is the role of char in C strings What is the role of char in C strings Apr 03, 2025 pm 03:15 PM

In C, the char type is used in strings: 1. Store a single character; 2. Use an array to represent a string and end with a null terminator; 3. Operate through a string operation function; 4. Read or output a string from the keyboard.

Avoid errors caused by default in C switch statements Avoid errors caused by default in C switch statements Apr 03, 2025 pm 03:45 PM

A strategy to avoid errors caused by default in C switch statements: use enums instead of constants, limiting the value of the case statement to a valid member of the enum. Use fallthrough in the last case statement to let the program continue to execute the following code. For switch statements without fallthrough, always add a default statement for error handling or provide default behavior.

How to handle special characters in C language How to handle special characters in C language Apr 03, 2025 pm 03:18 PM

In C language, special characters are processed through escape sequences, such as: \n represents line breaks. \t means tab character. Use escape sequences or character constants to represent special characters, such as char c = '\n'. Note that the backslash needs to be escaped twice. Different platforms and compilers may have different escape sequences, please consult the documentation.

How to convert char in C language How to convert char in C language Apr 03, 2025 pm 03:21 PM

In C language, char type conversion can be directly converted to another type by: casting: using casting characters. Automatic type conversion: When one type of data can accommodate another type of value, the compiler automatically converts it.

What is the function of C language sum? What is the function of C language sum? Apr 03, 2025 pm 02:21 PM

There is no built-in sum function in C language, so it needs to be written by yourself. Sum can be achieved by traversing the array and accumulating elements: Loop version: Sum is calculated using for loop and array length. Pointer version: Use pointers to point to array elements, and efficient summing is achieved through self-increment pointers. Dynamically allocate array version: Dynamically allocate arrays and manage memory yourself, ensuring that allocated memory is freed to prevent memory leaks.
