Very odd "If value >= x" Error

I made a page with a gridview that has rows show a different color if a
number in a column is greater than or equal to 45. I also did this
conditional formatting for the column next to it. Here's my code.

in the aspx file
=============== =============== =
<asp:GridView ID="gvData" runat="server" OnRowDataBound= "doColor">
=============== =============== =

in the aspx.vb file
=============== =============== =
Sub doColor(ByVal sender As Object, ByVal e As GridViewRowEven tArgs)
If e.Row.RowType = DataControlRowT ype.DataRow Then

If e.Row.Cells(10) .Text >= "60" Then
e.Row.BackColor = Drawing.Color.L ightYellow
e.Row.Cells(10) .ForeColor = Drawing.Color.R ed
e.Row.Cells(10) .Font.Bold = True
End If
If e.Row.Cells(9). Text >= "45" Then
e.Row.BackColor = Drawing.Color.L ightYellow
e.Row.Cells(9). ForeColor = Drawing.Color.R ed
e.Row.Cells(9). Font.Bold = True
End If

End If
End Sub
=============== =============== =

The Cells(10) statement works great. Only those results that are greater
than or equal to 60 are in bold red with yellow highlight.

On the Cells(9), however, its another story. For some reason, every
result that is 5 is also bold red highlighted. I tried changing the code
to this:

If e.Row.Cells(9). Text <= "4" Then

And the 5s are no longer in bold red. In fact, if I try any of these

If e.Row.Cells(9). Text >= "9" Then
If e.Row.Cells(9). Text >= "8" Then
If e.Row.Cells(9). Text >= "7" Then
If e.Row.Cells(9). Text >= "6" Then

Then if the text in the cell is 5 it is not in bold red. Once I put in
two digits, like so ..

If e.Row.Cells(9). Text >= "10"

Then the number 5 turns bold red. It should only be bold red if it is 10
or greater!

I also tried this, which works fine; the number 5 (or any other number)
is not in bold red, only the number 55 ...

If e.Row.Cells(9). Text >= "55"

I know i'm trying to do numerical conditions on text, which seem to work
anyway for cell 10. Just to test it, I tried to convert the value of the
text to an integer before the test, like so,

If CInt(e.Row.Cell s(9).Text) >= "10"

This only returned an error and I couldn't find any other way to convert
the text into an integer to do the condition check.

Any ideas on this strange error? Its very frustrating.

TIA,
Jim

Hi Jim,

You're not going to get the results that you desire by performing textual comparisons as if they are numeric.

You specified that you tried to convert the number but that it is failing, probably due to invalid or null data. To avoid the
conversion error first check if the Text property can be converted to an integer. If you're using the 2.0 framework you can use
Int32.TryParse, otherwise you can just catch the exception.

Hi Jim,

The first error (blue line) clearly states that you haven't specified all of the required arguments for the TryParse method.

Int32.TryParse on MSDN:
http://msdn2.microsoft.com/en-us/library/f02979c7.aspx

The second error, FormatException , occurs because the Text property of the cell is not returning a value that can be converted into
an integer. As I said in my previous post, you can catch the FormatException if you want, but I think TryParse is the better
choice.

Hi Jim,

Your first attempt shouldn't have even built (I suspect that it did because VB doesn't require explicitly marking "out" arguments
and that's a shame). You still don't have the arguments correct for the Int32.TryParse method. Look at the link I posted for more
info.

In your second attempt you are not catching FormatException , you are catching all Exceptions. I must advise against that.

I've already answered your last question with two possible solutions. Maybe you are miscounting the row index, which is zero-based.
i.e. The first column has an index of zero, the second column has an index of one, the third column has an index of two, etc. You
also have to account for hidden columns when determining the index to be used.

Int.TryParse returns a bool so you want something like (in C#):

int Globalization.N umberStyles.Any ;
int.TryParse(e. Row.Cells(10).T ext, Globalization.N umberStyles.Any );

if (Globalization. NumberStyles.An y 45)
{
}
etc...

Hi Kevin,

Your example wouldn't even compile.

System.Globaliz ation.NumberSty les is an enumeration, not a variable name. Also, the method returns a Boolean, as you mentioned, but
in your example your not event using it.

Int32.TryParse method on MSDN:
http://msdn2.microsoft.com/en-us/library/f02979c7.aspx

I recommend taking a look.

I'm typing the code into notepad - I was just trying to get across the
idea that you can't use the return from TryParse as that is a bool, but
instead need to set the "out" variable to get the actual result of
TryParse.
System.Globaliz ation.NumberSty les is an enumeration, not a variable
name.
I didn't bother checking the type of the variable he was using, assuming
it would be an int
Also, the method returns a Boolean, as you mentioned, but
in your example your not event using it.
And in this case I don't need to. if the method fails then the value
being set will still be 0 which is less than 45 the last time I looked!
I recommend taking a look.
Thanks for the advice but I now exactly how it works.
