Once loaded, it is Hyperfast! Are there some perfomance tips that I should be aware of? Would Load-on-Demand be a better option?</p>http://www.intersoftsolutions.com/Community/Tags/ISLinqDataSource/Fri, 23 Oct 2009 06:12:21 GMTsomer@optima.com.trClientBindingFilterPagingISLinqDataSource<p>I have a webgrid with clientbinding and paging which is connected a ISLinqDataSource (Datasource is Entity Framework).</p><p>I would like to return filtered data, but i cant use "filter column" property because of the design and security issues (for example: user may unhide hidden column and clear filter, or i can't apply more than one filter for a single column like "code like 'a%' or code like 'b%' ").</p> <p>And i cant use ISLinqDataSource's where property as WebGrid overrides it.<br /></p> <p>So i dediced to use FilteredColumns.AdvancedFilterExpression property.</p> <p>It runs but has one important problem:</p> <p>AdvancedFilterExpression is applied not while querying database, but applied after retrieving data by WebGrid. So if you set paging with 25 rows, you may see less than 25 rows in a pages, even may be all pages with no rows. </p>
