format decimal value in gridview

Question

I have a bound field in my Gridview which is getting its value from a database table.

I have got the data but don\'t know how to format it inside the gridview.

Answer 1

A couple of ways in how you can do that

Option 1

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "GetFilesFailed.aspx?id="+Eval("MachineID") %>' Text='<%# Bind("NumFailedFiles","{0:n0}") %>'></asp:HyperLink>

Option 2

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "GetFilesFailed.aspx?  id="+Eval("MachineID") %>' Text='<%# Bind("NumFailedFiles").ToString("N") %>'></asp:HyperLink>

Option 3
Create a method in the code behind page that returns the formatted number.

 protected string GetFormatedNumber(object number)   
 {  
   if ( number != null )  
       {  
          return number.ToString("N");  
       }  
       return "0";   
 }  

And call the method in your aspx page as below:

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "GetFilesFailed.aspx?  id="+Eval("MachineID") %>' Text='<%#GetFormatedNumber(Eval("NumFailedFiles")) %>'></asp:HyperLink>

Answer 2

I think you need to take a look at this MSDN article on How to Format Data in the DataGridView

Answer 3

if you want to format your data on gridview use "{0:n3}"

 <asp:Label ID="label" runat="server" Visible="true" Text='<%#DataBinder.Eval(Container.DataItem, "data","{0:n3}") %>'></asp:Label>

Answer 4

Use DataFormat property :

<asp:BoundField DataField="totaldata" HeaderText="Total Data"  
     ReadOnly="True" SortExpression="totaldata" DataFormatString="{0:n3}" />

EDIT : For the second part of your question use Eval method's second parameter to format your data :

<%# Eval("NumFailedFiles", "{0:n3}") %>

Then your template will be like that :

<asp:TemplateField HeaderText="Failed Files" 
    SortExpression="NumFailed">
    <ItemTemplate>
     <asp:Image ID="Image2" runat="server" 
         ImageUrl="~/NewFolder1/warning_16x16.gif" />
        <asp:HyperLink ID="HyperLink1" runat="server" 
                 NavigateUrl='<%# "GetFilesFailed.aspx?id="+Eval("MachineID") %>' 
                 Text='<%# Eval("NumFailedFiles", "{0:n3}") %>'></asp:HyperLink>
    </ItemTemplate>
</asp:TemplateField>
