Hi Can query string be accessed in HTMLHelper extension methods. We need to render differently depending on the querystring in the request.

The value of Request. QueryString(parameter) is an array of all of the values of parameter that occur in QUERY_STRING. You can determine the number of values of a parameter by calling Request. QueryString(parameter).
It binds the model object to HTML controls to display the value of model properties into those controls and also assigns the value of the controls to the model properties while submitting a web form. So always use the HtmlHelper class in razor view instead of writing HTML tags manually.
An HTML Helper is just a method that returns a string. The string can represent any type of content that you want. For example, you can use HTML Helpers to render standard HTML tags like HTML <input> and <img> tags.
Yes, through the current context, which is a property on HTML Helper.
public static string DoThis(this HtmlHelper helper) { string qs = helper.ViewContext.HttpContext.Request.QueryString.Get("val"); //do something on it } Sure:
public static MvcHtmlString Foo(this HtmlHelper htmlHelper) { var value = htmlHelper.ViewContext.HttpContext.Request["paramName"]; ... } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
