<asp:TemplateField HeaderText="Amount" ConvertEmptyStringToNull="False">
<ItemTemplate>
<%#GetQTY1(float.Parse(Eval("Sub_ContractAmt").ToString())).ToString("N2")%>
</ItemTemplate>
</asp:TemplateField>

if my data base field has any value then it shows no error. but if this fiels is null then it shows error
input string was not in correct format while binding the gridview.

so can you please tell me the method that if this field has null value then what should I do so that i dont get this error. this fields might be null.

Forms Data Controls :: Input String Was Not In Correct Format?

Mar 5, 2011

I'm stumped on this one... it seems really simple, but I can't get around it. I am pulling 2 values (discount percent, discount amount) from a formview label control. I want to use these numbers in a calculation, but I can't seem to get the format correct.

I hit the error on this statement:

DiscountAmt = Convert.ToDouble(fvDiscountResults.FindControl(
"DiscountSubtotal1"
).ToString)

Forms Data Controls :: Getting Error - Input String Was Not In Correct Format?

May 13, 2010

I have a Data field of type "Integer" below is my Edit Template for this Data field

<asp:TextBox
ID="OfficeSqFtTextBox"
runat="server"
Text='<%# Bind("OfficeSqFt", "{0:#,0}") %>'

Here is my problem When I try to edit this record, in the Edit mode, this Data field shows the number correctly with formatted e.g. 22,344 if I click on Save the record, it will give me the error "Input string was not in correct format". If I edit this number and remove the "," between numbers then it saves. What can I do to make this work? If I remove the "{0:#0}" then in the edit mode the number will show as 22344 without any comma separation. Note: On the same page I have other Data field of type "Money" and it works with the format applied ???? why does it works with the Money type and not Int???

Forms Data Controls :: Choose Selectedindex In Gridview / Input String Was Not In A Correct Format

Dec 27, 2010

I'm trying to populate a detailsview according to the selected row in a gridview. How do you choose what the selectedindex is? For example my sql statement is:

SELECT [Assignment_ID], [Staff_ID], [Client_ID], [Day], [Month], [Year], [Start_Time], [Job_Type], [Billable_Time], [Travel_Time], [KM_Travelled], [NC_Time], [SP_Time], [Billed], [Description] FROM [Assignment] WHERE ([Assignment_ID] = @Assignment_ID)

and @ assignment_ID is gridview.selectedindex

but when it runs I get the error:

Input string was not in a correct format.

Forms Data Controls :: Error Saying "Input String Was Not In A Correct Format"?

Apr 6, 2010

I'm retreiving information from a Progress database and databinding it to a repeater control. The line with repeater1.databind() gets an error saying "Input string was not in a correct format". The weird thing is that I only get it for one specific date, ie. when I choose rows based on a date in a specific column. That would suggest there is something wrong with the data in these rows, but I cant find anything. And you basically can not put anything "corrupted" in it, its a commercial system which I have not developed myself.

What are the possible reasons for this error? Why does it trigger on databinding and not when, for instance, I try to convert a value?

Forms Data Controls :: Error -"Input String Was Not In A Correct Format" After Upgrading To 4.0 (VS 2010)

Oct 22, 2010

I have a gridview that was displaying and handling postbacks correctly, that is, until I upgraded to .net 4.0 (vs 2010) from .net 3.5. Now I am getting the classic (and in this context meaningless) "Input string was not in a correct format" error upon postback. The postback is initiated by a command button and the row command event handles everything nicely.

The trace shows internal grid postback handling and nothing else:

[FormatException: Input string was not in a correct format.]
System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) +9594283
System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) +119
System.Convert.ToInt32(String value, IFormatProvider provider) +48
System.Web.UI.WebControls.GridView.HandleEvent(EventArgs e, Boolean causesValidation, String validationGroup) +1047....

From experience, I know this happens on late binding with wrong type casting on the ASPX side of things. However, nothing has changed. The code is the same, the only thing that changed is the upgrade to 4.0.

I have tried everything I (and a coleague) can think of to figure out what the issue is without luck. No error is raised on the code behind in any method. The only error raised is the Page_Error event and the error object contains the same crap you see in the yellow screen dump (above).

UPDATE: I narrowed the issue down to the RaisePostBackEvent method. I had to reflect the System.Web (for educational purposes of course :) assembly to figure out the code executing after my RowCommand logic(which is fine) breaks. This happens in the HandleEvent method. It checks for known command names (e.g. Select) and if it can't find a match, it defaults to the following:

[Code]....

Is this a bug or am I doing something wrong? The row object is NULL which is why it defaults to the cast. The cast assumes the argument to be an integer however and in my case I am passing a string as an argument?
