Using CRUD operations with Spread for ASP.NET provides useful database functionality along with an intuitive interface. You can use ADO.NET code and a SQL Server with Spread for ASP.NET with just a little bit of coding to connect everything.

Modify Data at Run Time

How you modify report data (connection strings and SQL queries) depends on the report type you use. Let's take a look at each report type.

DevChannel Update: Spread.Sheets v10 Preview with Client-side Excel IO Available

Our DevChannel delivers pre-release previews of next version builds and hot fixes. The first entry is a preview build of v10 which is due to release in November. This build has an early version of the new client-side ExcelIO feature. You can now implement Excel import and export functionality on the client and you no longer need to implement the .NET server component. This makes Spread.Sheets applications much easier to distribute and removes dependencies on IIS. Keep in mind that this is a very early preview and many Excel features are not yet supported. We have a special DevChannel forum in which you can discuss any problems you may be having.

Setting Report Permissions

Allow Users to Control Grid Settings with FlexGrid and Angular 2

FlexGrid allows you to access many different options and properties of the control to customize and configure behaviors to meet project needs. But in some cases, you may want to empower your end user with control of certain features of the Grid without cluttering up your user interface with controls. In this blog, we'll dive into how to add a glyph to the FlexGrid, allowing the users to configure their own interface and keep the page looking clean. By exposing properties or behaviors to the end user and using a data binding framework such as Angular 2, you can easily make a menu so end users can customize on the fly.

Sticky Headers: A Case Study in Customer-Driven Development

The FlexGrid, first developed 20 years ago, has evolved with our customer base, moving into new platforms, devices, and frameworks as the market demands.

SpreadJS Camera Shapes

Camera Shapes in Spread for WinForms allow the developer to take snapshots of content in a range of cells for use in other areas of the sheet, or different sheets entirely. This can help with organizing and presenting data in one cohesive view without having to worry about constraints on that view. In particular, camera shapes help make creating dashboards and complex reports simple and easy. In this blog post, I will show you how to create a custom CameraShape class for use in SpreadJS.
