Forms Data Controls :: ObjectDataSourceView.BuildDataObject Throwing IndexOutOfRangeException?
Jan 27, 2010
I've got a FormView bound to an ObjectDataSource. The FormView/ODS selects and displays my data correctly but when I change the data and try to update,nothing (seemingly) happens.Stepping through the code and digging deeper into the stack trace and output window,I figured out that the following sequence of events happens:
- The ObjectDataSource drills down to System.Web.UI.WebControls.ObjectDataSourceView.BuildDataObject to create the object I specified in the "DataObjectTypeName" property
[code]...
- Here is where the IndexOutOfRangeException happens. Sometimes one or two of the data object's properties will be set, sometimes none. Either way, the exception is thrown and the sequence is stopped (the business object's update is never called).
- The exception is not thrown inside any of the properties' set methods.I'm assuming that the exception is happening when BuildDataObject is using Reflection to find my data object's properties (GetProperty() etc.. ). Since I can't see the source code of BuildDataObject and the debugger won't give me any more information, there is no way for me to see which property (if any) is causing this.I double checked the names and types of all 27 of the data object's properties.

I'm trying to do a master-detail by first search the database when a user click on the search button. Then display the result to a ListView control. After that, if the user click on the hyperlink, it displays the detail on the Formview control. Below are my code:

And here's the part that causes the error:

The error is on this line: string strID = ltvLusHmoob.DataKeyNames[e.Item.DataItemIndex].ToString();

A dataview is throwing an out of range exception when a page submit button is clicked. The strange part is if you change the data in the dataview by selecting a different person in the DDL the page works fine. Its only when the page loads and the default person in the DDL is when the DataView throws the exception.
The exception is thrown on the last line when I add DV.Rows(0).Cells(1).Text to the id_num parameter. I know there is a value in the dataview because it is displayed on the page. I can refresh the dataview with another person's information and the code works fine. This really has me confused. Here is a bit of the code behind.
Dim dashDataSource

dashDataSourceInsertParameters.Add("id_num", DV.Rows(0).Cells(1).Text)

I'm trying to get data from a CSV file and add it directly into a database using Linq.
I'm using the following code:

The code works if I remove all the but the first property e.g.

But then I get the old "System.IndexOutOfRangeException: Index was outside the bounds of the array." exception when adding more columns.

I have the following web service:
[ScriptService]
public class Handler : WebService {
[WebMethod]
public void method1() {
string json = "{ "success": true }";
System.Web.HttpContext.Current.Response.Write(json);
[code]...
The first method accepts a traditional html form post and response writes a JSON string to the page.The second method accepts a JSON value posted via AJAX and returns a serialized object.Both these methods work fine on their own but when put together in the same web service I get this error when calling method1:
System.IndexOutOfRangeException: Index was outside the bounds of the array.
When I remove the arguments from method2 they work.Can anyone suggest why this is happening?
Edit:The problem spans from the argument type of method2. If I change it to a string or simple data type it works fine.As Joel suggests it's probably because Dictionaries can't be serialized.This doesn't seem to affect my requests sent by ajax and only breaks direct form posts to this handler.Therefore my workaround is to put the form post handlers in a separate file by themselves.Not ideal but works for my application.

I am having a little trouble with an 'IndexOutOfRangeException'. I think it is because when the code tries to get the DateModified col from the database it sometimes contains NULLS (the users haven't always updated the page since they created it).
Here is my code;
s = ("select datemodified, maintainedby, email, hitcount from updates where id = @footid")
Dim x As New SqlCommand(s, c)
x.Parameters.Add("@footid", SqlDbType.Int)
x.Parameters("@footid").Value = footid
c.Open()
Dim r As SqlDataReader = x.ExecuteReader
While r.Read
If r.HasRows Then
datemodified = (r("DateModified"))
maintainedby = (r("maintainedby"))
= (r("email"))
hitcount = (r("hitcount"))
End If
End While
c.Close()
I thought (after a bit of msdn) that adding;
If r.HasRows Then
End If
after adding I am still getting the same old IndexOutOfRangeException
(ps, I have tried datemodified as string / datetime)

What is the point of throwing an exception? It it anyways going to be caught in the Global.asax Application_Error method.
Lets say in the following code we throw an exception.
try {
using (var dc = GetDataContext())
{
// We are doing some data inserts here.
}
catch ( Exception ex)
{
throw ex;
}
My Question: Even if we do not use try catch and throw here, any exception which will be raised here will be caught inside Application_Error method in Global.asax. Then what is the point of try, catch and throw in this case?

I have an asp.net application with separate classes for business logic and database interaction and then of course the UI. I am building a form to add a widget to a widget list table in the database. My UI collects the information and submits it to the business class. I'm going to write the business class to first double check that the widget has a name (I know I should do this in UI with validation, and I will, but this is just in case validation is forgotten) and if it does, go ahead and send the information to the database class. The database class will then attempt to write the info to the correct table using a try catch finally block. Any errors caught here are logged and then rethrown so I can inform the user. So, knowing that my database class may rethrow an error, my business class code will also be written in a try catch finally block.
So at this point I have a number of possible outcomes that I want to inform the user via the UI:
1) Everything was fine and the widget was added.
2) Something happened with the database write and the user should try again later.
3) The user forgot to name the widget.
My question is: should I write my UI in a try catch block and then throw a custom Exception with an Exception.Message in the business layer if anything goes wrong, or just have my business logic return a string that is the message? I'll want to know if the process was successful or not, because I'll want to format the actual message differently, so I'd have to use if...elseif to determine if the message was bad or not.
It seems like throwing a custom Exception in the business layer may be a good way to tell the UI something bad happened. If the UI doesn't catch anything then of course the operation was successful. Then again throwing an exception for missing data seems a bit hefty.

We have an array of about 12 servers serving a website. Over the past few hours, one single server has started throwing exceptions for WebResource.axd and ScriptResource.axd requests.
Exception
System.Web.HttpException - This is an invalid script resource request.
Stack Trace
at System.Web.Handlers.ScriptResourceHandler.ProcessRequest(HttpContext context)
at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
Broken server URL
/WebResource.axd?d=S6kjkBsrIKni9uO5HCkv0c8eYObzibWXn9R6A7Yr_Fy7CW4dRFZm1HfcnUTEZ8xBYZDM-5zeTVk1tTgC1hp7d5YYw3o1&t=634308186300177825
All other servers URL
/WebResource.axd?d=yj6PW1hbOvqhMkOh2gYGlw2&t=634207187366247462
I have checked the web.config, machine.config for every server and they're all identical. The only difference been able to find so far is that prior to the problem commencing, the servers were patched, after which, the problematic server looks to be using different version of the System.Web.dll to the others?

i have just noticed something strange in some asp.net markup.
I have a standard form with a couple of textboxes and a submit button.
When clicked the code behind will attempt to perform some logic and then return.
If the input values are not valid it used to throw an exception.
The moment i wrapped the controls in an AJAX update panel and try to submit bad data, no exception is thrown and the panel returns like nothing was wrong.
Does anyone know how to return this to the previous behavior whilst keeping the update panel?

I have an ASP.NET page with code-behind in VB.NET. On the ASPX page I have a Repeater with an asp:ImageButton inside the repeater and I want to catch the clicks on the button. As far as I read I have to use FindControl and then handle the copy of the original control:
Codebehind:
Dim imagebutton1 As ImageButton = repeater.FindControl("btnImage1")
AddHandler imagebutton1.Command, AddressOf ReportTransfer
...
...
Protected Sub ReportTransfer(ByVal sender As ImageButton, ByVal args As CommandEventArgs)
...
End Sub
ASPX page:
<td>
<asp:ImageButton runat="server" ID="btnImage1" ImageUrl="~/images/icons/icon_small.png"
CommandArgument="3" />
</td>
</tr>
</ItemTemplate>
It throws "Object reference not set to an instance of an object" on the AddHandler line and I have no idea why it is doing it (I'm a bit new with VB.NET)
