DataSource Controls :: String Input Failing When Trying To Log On?
Feb 2, 2010
Having a bit of trouble with a logon page I created using text boxes for a User ID number and a password.
Basically, my original design was to have a textbox for a username and one for a password. Due to some complications, I changed the username to the User ID number input and as such, the input credentials went from being a string to an integer. I've changed this successfully, however when I now type in a string, rather than the integer it requires, the page fails.
how to edit this so if a user enters a string value instead of a numeric value, an error message can show up on a label instead of the whole project coming to a halt because of an error?
Here's the code I have for the page so far, which does the job (apart from this problem!)
using System;
using System.Data;
using System.Data.Sql;
using System.Data.SqlClient;
using System.Data.SqlTypes;
I have the textbox input the double number like 0.5 or 2.1 then click the submit insert to database, but show the error. Server Error in '/' Application. 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. Exception Details: System.FormatException: Input string was not in a correct format.
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]....
"System.FormatException was unhandled by user code - Input string was not in a correct format" This is driving me crazy! Can anyone see what the problem is?
I have a bound data field, a detailsview, one of the records I have formatted to currency in the item template. Yet when I go to delete a record, I get a error message "Input string was not in correct format". Take away the formatting and the page runs fine. I tried changing the datatype from int to money, it makes no difference.
I get the error 'Input string was not in correct format' currentID is an integer var. When I hover over the GridView_ABC.DataKeys[0].Value it is """, it should be an integer.
I am trying to pass a mysql reader string variable into a textbox so on the asp front end it will automatically show the resultset as soon as the page is loaded. The following is my code:
protected void Page_Load(object sender, EventArgs e) { if (!Page.isPostback)
I am using 1 textbox with a Ajax Calendar extender to allow my user's to select a date graphically (exp: 12/15/2009). I have another textbox for the hour and minutes in military time(exp: 15:30). I think i have the code to grab the data from the 2 textbox's and combine them to be inserted into the field (exp: 12/15/2009 15:30). Here is my insert code for the Field:
[Code]....
However unless I make all the fields Nullable the insert fails, on top of that none of the other field that I have selected on the Detailsview Insert or Edit are inserted into there fields. Half of my fields have to be non-null values. So how do I fix this?
I can supply additional vb code and the aspx code if needed.
This is the error I'm getting: Cannot insert the value NULL into column 'Operation_type', table '/GAOSDB.MDF.dbo.BC_Perf_Log'; column does not allow nulls. INSERT fails. The statement has been terminated.'
This is the first non-null column.
I need to get this figured out because I have 30 other web pages that will be utilizing the same approach.
//Read string contents using stream reader and convert html to parsed conent var parsedHtmlElements = HTMLWorker.ParseToList(new StringReader(contents), null); //Get each array values from parsed elements and add to the PDF document foreach (var htmlElement in parsedHtmlElements) pdfDoc.Add(htmlElement as IElement); //Close your PDF pdfDoc.Close(); Response.ContentType = "application/pdf"; //Set default file Name as current datetime Response.AddHeader("content-disposition",
[Code] ....
Error: Input string was not in a correct format. Contents in html file giving error ...
I'm getting "the input string was not in the specified format" on the last line of code below. The grid is based on a SqlDataSource that has a stored procedure pulling an integer for column 0.
I have tried using .NET's various encryption functions but all my encrypted strings are at least 24, 28 or 32 in length.
I have heard of CipherMode.CTS with Padding = None that produces the same length output as the input length but I can't seem to get the same result. I have toyed with the block-size, key-size and salt size.
I don't mind adding a digit to my input string to make it 16 in length.
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)
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 have a gridview which has a total column to total each row, and i am trying to add a label to total the column i have got this far:
But am receiving this error:
Input string was not in a correct format.

I'm concatenating a string in codebehind to use in a sql select statement.
in aspx
<asp:Label ID="LabelHidden" runat="server" Visible="False"></asp:Label> SelectCommand="SELECT * FROM [Data] WHERE [ActivityName] IN (@ActivityName) AND ([ID] = @ID)" <SelectParameters> <asp:ControlParameter ControlID="DropDownList_Employees" Name="ID" PropertyName="SelectedValue" Type="Int32" /> <asp:ControlParameter ControlID="LabelHidden" Name="ActivityName" Type="String" /> </SelectParameters> in codebehind foreach (ListItem li in ListBox_Activities.Items) { if (li.Selected) { queryBuilder += li + "', "; } queryBuilder = queryBuilder.Substring(0, queryBuilder.Length - 1); LabelHidden.Text = queryBuilder;
When i run the code it comes up blank. I did a query trace and it seems to be running as
exec sp_executesql N'SELECT * FROM [Data] WHERE [ActivityName] IN (@ActivityName) AND ([ID] = @ID)',N'@EmployeeID int,@ActivityName nvarchar(50)',@EmployeeID=4,@ActivityName=N'Production Technical Support'', Tools Development'','
with exta "'s
How can i format the queryBuilder string correctly in my code?
