Forms Data Controls :: Sum The Rows In A Gridview - Error / Input String Was Not In A Correct Format?
Jun 8, 2010
I am trying to sum the rows in a gridview. It works find except when I do an update. Then I get the following error:Input string was not in a correct format. The error occurs when it its the Total1 +=gr1.cells(5).text or the Total2 area. Here is my code to sum the rows:
I have a gridview to update soem records, it works on my development laptop but when i use it on the webserver i get the following error:
Exception Details: System.FormatException: Input string was not in a correct format.
Source Error: [Code]....
Stack Trace: [Code]....
I have another page with a gridview that does exactly the same but from another table, and that works both on the development laptop and the webserver.the code is:
i am creating a total column which multiplies the price by quantity in my gridview but am stuck on converting the input strings.
The price is stored as a decimal in my database and the quantity is a nvarchar.
i am receiving this error:
Input string was not in a correct format.
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

I have gridview control that has data binded by using EF. Whenever I try to sort my gridview I get this error: "Input string was not in a correct format." This error points to the following line of code: "int index = Convert.ToInt32(e.CommandArgument);"

I'm not sure what do I have to fix if I want to sort the columns.
If I bind the data manually what is the code for codebehind to allow sorting for particular columns.
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???
I got a "Input string was not in the correct format" exception but can't see the problem. The exception had no information to show what was causing the error. It's thrown before the BLL or DAL are called so it must be in the mark up. The parameters are in the right order.[Code]....
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:

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?
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?
I got this error: Input string was not in a correct format.

I revise 'Pro_Comp_ID' in sql and .net it all of datatype 'int' where is the error?

I get the Erorr: Input String was NOT a correct format.
The first three controlparameters are STRINGS and they work fine.
However the last two populate the controlparameter from text boxes that can only accept numbers and decimal point.
First the text boxes for {3} and {4} string parameters in the SQL filterexpression: [Code]....
And then the SQLDatasource control parameters[Code]....
The last two control parameters are the ones is question as they feed {3} and {4} parameters in the filter expression, NOTICE how I set the type="double".The data input is expected to be like 152.25 or 3.6 or 4 etc,So why am I getting this error: [Code]....
DataRow dr = GetCurrentEvents(int.Parse(Request.QueryString["ScheduleID"]));
ScheduleID is an int in my stored procedure. SoI inserted the (int.Parse) But now I get that error. How can I convert an int into the QueryString.?If I take out the (int.Parse) The method I have calling the above. Its something like:
private DataRow GetCurrentEvents(int ScheduleID)
{
some stuff
}
If I change it to (string ScheduleID). I get a different error bc I'm trying to convert an nvarchar to an int...
when I adding for first time it's added successfully but for the second time it raises this error:
Input string was not in a correct format. protected void btn_save_add_Click(object sender, EventArgs e) Line 147: { Line 148: pro.Pro_ID = Convert.ToInt32(txt_prodID_add.Text); Line 149: pro.Pro_Name = txt_prod_name_add.Text; Line 150: pro.CategoryProd_ID = Convert.ToInt32(ddl_ctegOf_Product_add.SelectedValue);
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.
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 am getting "input string not in correct format" error and I have tried a few variations and still no dice. zSessvar1 is equal to 159 and when I substitute the actual nbr, it will work.
Dim cmd1 As OleDbCommand = New OleDbCommand("Select nbrofcomments from table1 where PID = " + zsessvar1, myConn)
I am getting the below error when tryingn to do an Insert. Any words of wisdom would be great:

Is it legal to define a default value for a parameter the way I am in the code below? It keeps throwing an "Input string was not in a correct format." error for me. Is there a different way I should be doing this?
I create a project on my local host (xp) that work o.k.
I up load the project to the test server (win Server 2008), work o.k.
But when I up load the project to the production server (win Server 2008). It gets that exception(Line 303):
Input string was not in a correct format.
