Scrolling, Waiting, and Pagination

Methods for scrolling the page, waiting for elements or conditions, and handling paginated or infinite-scroll data sources.

Methods for scrolling the page, waiting for elements or conditions, and handling paginated or infinite-scroll data sources.

PageUp, PageDown, PageTop, and PageEnd scroll the document by page increments. ScrollWindowByVertical and ScrollWindowByHorizontal scroll by a specific pixel count. WaitFor pauses the workflow for a fixed time, until a selector is found, or until an element reaches a given state - see Waiting for Elements, State, and Time (WaitFor) for the full set of overloads and examples in every context. Until and While loop the current workflow until a condition is met or a selector is found. WithNextPageButton, WithPages, and WithInfiniteScroll configure automatic pagination when scraping multi-page data.

TIP

When using While or Until loops, set WhileLoopTimeout (milliseconds) and WhileLoopMaxIterations to prevent infinite loops in production workflows.

Examples

GPAL Fluent: High-level fluent C# API

//WithInfiniteScroll is a property (no parentheses). GPAL scrolls to the bottom of the page and waits for new content to load, repeating until no new elements appear or the match limit is reached.

// Wait for an element to appear GPAL.Browser .GoTo("https://example.com") .WaitFor("#results") .WithSelector(".result-row") .GetGrid(out var results); // Scrape all pages of a paginated table GPAL.Browser .GoTo("https://example.com/data") .WithSelector(".data-row") .WithAllThatMatch(500) .WithNextPageButton(".next-page") .WithPages(10) .SaveToCSV("all-data.csv"); // Handle infinite scroll GPAL.Browser .GoTo("https://example.com/feed") .WithSelector(".post") .WithAllThatMatch(1000) .WithInfiniteScroll .GetGrid(out var posts);
