    RadPageView – next generation WinForms navigation control

    As the new Q2 2010 release is approaching, we wanted to share some more information about our brand new control RadPageView, meant to supersede existing RadTabStrip and RadPanelBar. “Why yet another tab-strip?” someone would ask. Several are the major reasons that made us create this new control, namely: Extensibility, scalability and ease of use. With the new semantic that lies behind RadPageView, it is very easy to create custom views over a collection of pages. Well thought light element tree, which reduces both memory footprint and User Interaction response time and allows for easy and intuitive styling. Myriad of new features in...

    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...
