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();

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 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)

Basically, what I did is that: I have a table in SQL database and some of data fields allow null. I built Objectdatasource through dataset. When I built update page using dataset. It generate the following error before showing the update page correctly. It seems I have issue to retrieve the null value from the database through using objectdatasource through dataset. Any suggestions?An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code

Is there anyway in .NET to get an image offset position in the webform?Javascript can get this information from the "offsetX" and "offsetY" values but are there anyway to get the same info in .NET?Or can I use javascript to catch the info and send it to the backend? Like creating a hidden input field with the data and then read the data from the code behind?

I have found many articles claiming to show you how to set the scroll position of a ListBox, but what they really end up showing you is how to set the SelectedIndex of a ListBox.
Here is what I need: a databound ListBox that's usually going to have around 25 items in it. When the page loads, ALL of the items in the ListBox are selected, and the ListBox is scrolled all the way to the bottom.
I've got the "All items Selected" requirement already, but I can't figure out how to get the "Scroll to the bottom" done.

Above is my code. The error I'm get is, Unable to cast object of type 'System.DateTime' to type 'System.String'.
The column "To" and column "Subject" are strings and column "Receive" is DateTime. I can't made any changes in the database, so I need to write some code to handle casting a string to datetime or if statement as a work around.
