VS 2005 Error Index Out Of Range / Exception Was Unhandled By User Code
Jul 11, 2012
You can for example enter the length and width of the web (VS.NET2005), when it runs out of range index error exception was unhandled by user code for chieudai
I'm trying to throw the exception back to Page_Load but the throw statement causes error: ArgumentNullException was unhandled by user code. How can that be fixed? Also, I can't see Label1.Text displayed on the page after the ArgumentNullException occurs because the page is not re-load. If there is no exception, it's fine to not reload the page. How can I see the Label1.Text displayed?
I'm building a web app that to build a report, but there are too many arguments to give each one a name, and I want to save them indexed by numbers so I can handle them with loops later on throughout the application.However, I'm getting an index out of range on the very first session item(0)...as I understand it, I don't have to instantiate a session myself and this should work right?
I'm working on having two forms that communicate together. In order to do this, I am passing public value from the source page. Here's how I did it:
In the source page I have:
Public ReadOnly Property CurrentCity() As String Get Return txtboxfake.Text End Get End Property Then under page_load of the page I have: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load txtteam.Text = PreviousPage.CurrentCity txtboxdate.Text = Calendar1.SelectedDate End Sub
For some reason I keep getting an error that says "NullReference exception unhandled by user code" that points to txtteam.text = PreviousPage.CurrentCity.
I did executed a db - contact form page successfully in the same project with the same connection string, but for this page its doing error and so I commented the binary file saving codes and all and put just simple 2 fields to see if the db is connecting and surprisingly getting sqlexception error and no data is written to the db. I am using sqlexpress 2005 and VS 2008. After this code I am listing the error I got.

I have used the DataKeyNames property of the GridView to assign the column name whose visible property is set to false to get the cells value when the column is kept invisible. But, sometimes there is an error on this line of code - string cellValue = GridView.DataKeys[e.NewEditIndex].Value.ToString(); Following Error is generated -

I have a static dictionary object which hold some Key and Value pairs in our site.We are getting Indexoutofrange exception some times and we couldn't figureout the problem why it is causing.This error is logged several times in the log file and site went down.Do you have any idea why this is happend?Please provide your advice ASAP as we are facing this issue in live server.
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.

Actually I inherited this project, my job is enhance and debug this project. Just now my manager send me a log file ask me to debug, have no choose, I must settle this problem. according to the log file, I only know this bug occur in my login function,but I test in my local solution it can work well, no problem, it only appearing in live server. so I suspense it was server error, my manager ask me prove him, so any can explain to me what the log file mean? Event code: 3005
AutoGenerateColumns: Flase/True ( i tried both) If i remove the gvOff.Columns[index].HeaderText portions, GridView works fine, but when i put the gvOff.Columns[0].HeaderText, i get the exceptional error.
, i couldn't solve it. If you need further info, inform me.
EDITED:
Hold on! I commented the HeaderText portion and tested int i = gvOffer.Columns.Count; I found count is 0 eventhough the columns print out with DataBind()... Why? NOTE: AutoColumn in this case is set to true. I guess i will have to edit the column names from DataTable.

I downloaded a sample Rolodex from here: [URL] the file to download is at the bottom of the page and it is called 'RolodexDatalist.zip (6.71 kb)' So I changed the HTML to it points to my SQL Server DB. I changed the ConnectionString to this:

I'm stumbling on a basic LinqDataSource insertion problem. For some reason, I cannot insert records. The run-time returns the following error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index The mark-up is as follows with the InsertParameters group. Adding or removing the group leads to the same error. (Note that updating works fine):

The events are void (just a convenient way to to troubleshoot). However, the run-time error occurs before the events are fired.

I recently had to remove a field from my datakey on all three gridview tables. On the top level table the field (ignum) remains as a non key field. On the two lower level tables it was removed completely. Now, the top level gridview opens correctly, but when I click on select this should bring up all the records in the second gridview associated with the selected row in the first gridview, but I get the following error:
[Code]....
I've looked at everything I can thing of and everything looks ok. The tables look good, I've removed all references to the removed field and I've restructured all the code to account for the changes. I'm missing something, but I don't know what. I've gone through debug step by step and the error occurs as I leave the GridView1_SelectedIndexChanged code. It goes down to the End Sub line with no errors, but when I step again it errors out. Here is that section of code.
