Hi,
We are trying to implement virtual scrolling using the UltraWebGrid.
The rows in the grid are non-hierarchical.
We used Browser="XML" in UltraWebGrid and LoadOnDemand="Xml" XmlLoadOnDemandType="Accumulative" RowsRange="50" under DisplayLayout.
We also added the InitializeDataSource event where we load the dataSource (Sql DataTable) to the grid.
gridMatrixDetails.DataSource = mySQLDataTable
gridMatrixDetails.DataBind();
The grid loads without any error & we see first 50 records. However, as we scroll down to get the next set of 50 records, we get a 'refresh' icon on the grid momentarily. However, the next set of 50 records are not loaded. We still see the 50 records that were loaded initially.
We do not get any javascript / .net errors either.
Please advise or provide sample code.
Regards,
Mithilesh
Hello,
Please note that the version you are using is retired several years ago and understandably would not work with modern browsers that were released after the last volume of the classic controls, which was Infragistics NetAdvantage v11.1 of ASP.NET.
The product lifecycle is stated in the following page:www.infragistics.com/help/product-lifecycle.The only possible solution in this case is to use a product that is supported under newer browsers, which you can identify in the supported environments page at:http://www.infragistics.com/support/supported-environments.So what you could do is to upgrade to the new ASP.NET Ajax tool-set. You can take a look at it at:http://www.infragistics.com/products/aspnet.
