Can anyone tell me what syntax to use in an asp.net datagrid column so that a numeric value will show as blank if it is zero ?

if(e.Item.ItemType != ListItemType.Header && e.Item.ItemType != ListItemType.Footer)
{

if( e.Item.Cells[0].Text=="0")
e.Item.Cells[0].Text=" ";

}

// in item databound - assuming 1 column is the one you wat to manipulate

Is there a way of doing this in the dataformatstring eg something like dataformatstring="{0:N0}" ?

Best solution is to get the number in string format from the sql.

Assume you have a column named "Price", then instead of

Select price from table1

do

Select
CASE CONVERT(VARCHAR(10), PRICE)
      WHEN '0' THEN ''
      ELSE CONVERT(VARCHAR(10), PRICE)
 END
AS Price
From Table1


Cheers,
S Sansanwal

Hi, there
Below code worked for me in VB.NET
Couple downers: 1) It didn't work in C#.NET
 2) You have to use TemplateColumn instead of BoundColumn

<asp:TemplateColumn>
  <ItemTemplate>
     <asp:Label ID="lblCol1"
        text='<%# iif ( DataBinder.Eval   (Container.DataItem, "COL1" ) <> 0,  
        DataBinder.Eval(Container.DataItem, "COL1", "{0:#,###.#0}"), "" ) %>'  
       Runat="server">
    </asp:Label>
  </ItemTemplate>                  
</asp:TemplateColumn>
