    Bringing User Experience to the next level in RadGridView for WinForms

    In the upcoming Q3 2010, we bring the extensibility of RadGridView to the next level.

The new feature gives developers the opportunity to extend the default behavior of all descends of the GridViewRowInfo class.

    Explained: RadGridView for WinForms virtualization and its implications. The case with CellElement and RowElement

    As the Logical vs. Visual Grid Structure help article states, RadGridView for WinForms uses virtualization for its cells/rows and as of Q2 2010 there is column virtualization as well. What is virtualization? To put it simply, when you bind RadGridView to a DataTable with 1000 rows, you get 1000 data row objects created in RadGridView (of type GridViewDataRowInfo). However, not all data row objects can be visible at the same time in the RadGridView estate in your application. This is why only the visual rows that can be shown in the estate get created (these visual rows are of type GridDataRowElement), or about...

    New goodies in RadGridView for WinForms: Drag and drop with RadGridViewDragDropService

    One of the new goodies that came with RadGridView Q2 2010 is the brand new drag and drop API, which offers a very flexible way to create custom drag and drop scenarios with ease. Each instance of RadGridView is associated with RadGridViewDragDropService that handles user drag and drop operations. It gives you out-of-the-box reordering of columns and movement of items between the group panel and the columns header. The service is also responsible for rows reordering in unbound mode when grouping and sorting features are not applied. In many cases, developers need to implement complex custom scenarios that are not covered by our products by default....

    Styling Cells in RadGridView for WinForms

    In RadGridView you have to handle the CellFormatting event when you want to customize the look and feel of grid cells. This is so because RadGridView uses UI virtualization. It creates elements only for cells that are currently visible - when scrolling they are reused. Of course, it will be much easier if we could access the cell directly and set its visual properties without an event. In our next release (Q2 2010) this will be possible. By using the Style property you can set the desired background color or change the font size. Here is a sample: this.radGridView1.Rows[5].Cells["Name"].Style.BackColor = Color.Red; this.radGridView1.Rows[5].Cells["Name"].Style.Font = new Font(SystemFonts.DialogFont, FontStyle.Italic);   All...
