I want to show Components in a tabs , so first of all create few components. In this project we have three components, First View Component public class AllViewComponent : ViewComponent { private readonly UserManager<ApplicationUser> _userManager; public AllViewComponent(UserManager<ApplicationUser> userManager) { _userManager = userManager; } public async Task<IViewComponentResult> InvokeAsync() { List<StudentViewModel> allUsers = new List<StudentViewModel>(); var items = await _userManager.Users.ToListAsync(); foreach (var item in items) { allUsers.Add(new StudentViewModel {Id=item.Id, EnrollmentNo = item.EnrollmentNo, FatherName = item.FatherName, Name = item.Name, Age = item.Age, Birthdate = item.Birthdate, Address = item.Address, Gender = item.Gender, Email = item.Email }); }
Conditional formatting refers to the formatting of data based on a specified criteria or condition . For example, while creating a list of famous sportsmen, you might want the names of the sportsmen who play your favorite sport to appear in red. You can specify this condition in your XML document using XSL Transformations (XSLT).
The two XSLT elements that you can use to specify conditions for formatting XML
Documents are:
The two XSLT elements that you can use to specify conditions for formatting XML
Documents are:
- The if element
- The choose element
The if Element
The XSLT if element provides a simple if-then construct. The syntax of the if element
Is:
<xsl : if test = “condition”>
[ actions to be performed if the condition is true ]
</xsl : if >
In the preceding syntax, the test attribute specifies the criteria for performing the specified action, and condition specifies a Boolean expression that evaluates to true or false. For example, to display the names of products priced higher than $100, you can use the following code:
<xsl : if test =”PRICE[ . > ; 100]”>
<xsl : value-of select=”PRODUCTNAME” />
</xsl : if>
The choose Element
The choose element enables you to choose from two or more possible courses of action. It enables you to test multiple conditions.
The choose element must contain one or more when elements. It can contain only one optional otherwise element, which must appear after all the when elements. A choose element with only one when element behaves similar to the if element. With two or more choices, the choose element behaves like an if-then-else or switch-case construct.
The syntax of the choose element is:
<xsl : choose>
<xsl : when test=”condition”>
[action to be taken]
</xsl : when>
:
:
<xsl : otherwise>
[action to be taken]
</xsl : otherwise>
</xsl : choose>
Identifying Comparison and Boolean Operators
The choose and if elements can be used with comparison and Boolean operators to narrow down the conditions based on which the XML document is formatted. The following table lists the various comparison and Boolean operators.
