Is there a simple way to have a checkbox in a GridView bound to a column in the database table that is a CHAR(1) column with a value of "Y" or "N"? I have the GridView bound to an SqlDataSource control, but if I need to bind the GridView to a DataSet created in the code-behind, I could do that, too. The data is coming from a Stored Procedure, so I could also modify the proc to return a boolean instead of the Y/N, but I also need to do an "add" and "update" through the GridView, and so that would also mean modifying those procs to translate the boolean value from the GridView into the Y/N needed by the database table.

Any of these would be simple enough to accomplish, but I'm just wondering about how to go about binding a checkbox to a CHAR(1) column.

You can use helper function to accomplish this:

C# example:

<asp:CheckBox ID="CheckBox1" Checked='<%# ((string)Eval("FieldInDatabase") == "s") %>' runat="server" />
