dataset/GridView calculation

[igotyourdotnet]

I have a dataset that is populating my gridview, but I have a data in the
dataset coming out like .011 and showing in the gridView as .011%. I need to
calculate that so it shows as 1.1% and not .011%. How can I do that and still
bind it to my gridView without having to make that calculation on the
database side?

that didn't work, I'm still getting:
..011 and not 1.1%

I have this
<ItemTemplateField>
<asp:Label runat=server text='<%#Convert.ToDouble(Eval("value")) * 100
%>'></asp:Label>
</ItemTemplateField>
and its showing in my gridView as .011 still.

Hi,

I tried that using Northwind Access database, and it seems the expression
should work. What's the data type of underlyiny field in the DataSet?

Also, actually you don't need to do that convert by hand, GridView has a
DataFormatString that can do that for you:

<asp:BoundField DataField="UnitPrice" DataFormatString="{0:P2}"
HtmlEncode="false" />

its a calculation coming from the stored procedure.
Also, I did the expression in a template field, so how will
asp:BoundField DataField="UnitPrice" DataFormatString="{0:P2}"
HtmlEncode="false" /- this work in a templateField?

I'm using this on other values in the grid but their not templateFields

Hi,

Sorry for late reply.

For TemplateField, when using Eval or Bind to get the bound data, it can
use another parameter to specify a format string:

<ItemTemplate>
<asp:Label runat="server" ID="lbl1" Text='<%# Eval("value", "{0:P2}")
%>'></asp:Label>
</ItemTemplate>

However, after I reviewed your question again, I suspect it might still not
work for your case. Since using your "Convert.ToDouble" code on my side
will work correctly, I think it might be related to the data type of the
field "value" in your DataSet.

I've done following test using a VARCHAR field:

1) If I use DataFormatString or Eval/Bind with format string "{0:P2}", it
will not work, it will still display "0.011".

2) If I use your original code 'Convert.ToDouble("value")) * 100', it
should display "1.1" instead.

Is it possible for you to create a small reproducible project to show this
issue? I will have to have such a project to find the root cause of this
issue. Thank you for your effort and understanding.

I got this to work actually. I created a variable in the code behind and
bound that to my grid.
