This article shows how to bind a *RadGridTemplateColumn *that contains a *RadColorPicker *to a SqlDataSource. The code for inserting a new record to the DataBase and updating an existing record are shown in the attached projects.
The MSSQL server does not have a type that corresponds to the System.Drawing.Color type in .NET. The RadColorPicker control works with that .NET type, however.
In the attached sample a column of type nvarcharis used to store the value of the color (an example value is: #66CC99) in the SQL server. The FromHtmland ToHtml static methods of the System.Drawing.ColorTranslator class are used in order to parse a string to an object of type System.Drawing.Color and vice-versa. The zip files bellow contain the full source code of the implementation in VB.NET and C# including the database file used in the sample.
