Re: GWT GridPanel max no. of row can be populated

Thanks for the reply, com.gwtext.client.widgets.grid.GridPanel is in use. And can't replace that with another widget right now.

What is the maximum no. of rows com.gwtext.client.widgets.grid.GridPanel can support? I agree with the idea of displaying limitied no. of rows to have optimized features like sorting, filtering etc. But here I have huge amount of data in range of 50K-350K(rows). But com.gwtext.client.widgets.grid.GridPanel with more that 5000 rows giving Store Load Exception. Looking for possibility to display around 10K-20K in the GridPanel. Any specific property for that?

GWT only has a widget called "Grid" that is not limited in row size other than its decreasing performance the more rows/columns you add. An alternative is CellTable that supports pageable content and is meant to manage large data sets.

In general its a good idea to only show a limited number of elements and give the user sophisticated search/filter possibilities. No one really scrolls through 20000 rows of data unless he is maybe called "Data" from Star Trek :)
