I have a gridview contains this column

C#

<asp:BoundField DataField="Total" HeaderText="<%$Resources:Labels, Total%>" DataFormatString="{0:F3}"/>

and I have this variable in code behind

C#

public static class Features
 {
   public static int Decimals = 1;
 }

I want to replace number "3" with the variable Decimals in

C#

DataFormatString="{0:F3}"/>

DataFormatString="{0:F<%=Features.Decimals%>}"

C#

DataFormatString='<%="{0:F"+Features.Decimals+"}"%>'

nothing works

I haven't really tried passing a variable to a DataFormatString, and I'm not sure if that is going to work. You may want to handle the formatting at your code behind page instead. For example, you can do something like this at DataBound event of GridView:

C#

//Where ColumnIndex is the column position. Note that index starts at 0
((BoundField)GridView1.Columns[ColumnIndex]).DataFormatString = YourCustomFormatStringVariable;
