    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...

    Flexible data conversion with RadGridView for WinForms vNEXT

    One of the new features that will come with the next version of RadGridView is the new data conversion layer. In our daily work we have often got into troubles in visualizing and formatting concrete types as other types. Sometimes the data source is not compatible with the bind target. Hence, you need to create a facade that converts the data to desired type. Let’s say that you bind the grid to a source that is incompatible with the columns that you want to show, for example a GridViewCheckBoxColumn for char field instead of GridViewTextBoxColumn. How can you accomplish that? The new version of RadGridView will...

    RadGridView for WinForms vNEXT is coming

    The new version of RadGridView is coming in May (as beta) and I am eager to show you some of the new features. There are many methods to indicate errors in RadGridView. However, until now it didn’t support the most natural and easy way for this - the IDataErrorInfo interface. Things have changed, so let me show you how to use this interface.   As MSDN says,“IDataErrorInfo provides the functionality to offer custom error information that a user interface can bind to.” Actually, you don't need to know anything about this interface. You can just set the ErrorText property of the desired row or cell: this.radGridView1.Rows[5].ErrorText = "There...

    Upgrade Existing WinForms Applications to Use the Latest RadControls

    Upgrading projects to new versions can be a pain, especially when you have to update several assemblies from a single version, as is the case with RadControls for WinForms. Q1 2010 simplifies this process a lot, by giving a couple of ways (one new and one updated) to upgrade existing applications to the latest and greatest version of RadControls for WinForms: By using the new Visual Studio Extensions (VSX), available in VS2005, VS2008 and VS2010 RC; By using the updated Project Upgrade Utility. Here are the steps: Upgrading a classic Windows Forms application to the latest RadControls for WinForms by using the Visual Studio Extensions Install...

    WinForms RadGridView vNext will feature new hierarchy modes and performance improvements!

    During the past year, we received many suggestions for new features and bug fixes for RadGridView for WinForms. After analyzing them we realized that we should do a major refactoring of both the data layer and the UI of our grid control. Then we set an ambitious goal -- to refactor the control and implement the most wanted features. This is obviously a massive task and the new grid control will not be part of Q1, but it is coming up afterwards as beta, and will be officially available for Q2 2010. This will give us enough time to test all...
