ArgumentOutOfRange on set ComboBox.SelectedIndex

G

Guest

Hi,

I'm getting an ArgumentOutOfRange being thrown from a ComboBox that has a
DataBinding on SelectedValue to a public property on a class. The DataSource
of the ComboBox is a DataTable that has had a row inserted into it (via
DataTable.Rows.Insert( row, index ) ). After a row has been inserted, I can
no longer bind. If I append a new row using the Add method instead of
inserting it, the table binds fine.

Is it not possible to bind with a DataTable that has had rows inserted?
Seems to me the index its returning is incorrect, considering I said insert
at 0, and its saying -2147483642...

Any enlightment is greatly appreciated. The error details and actual stack
trace are below, along with the sample code to reproduce the error. This is
on framework v1.1, btw.

Thanks,
Nathan Ernst

The error information I get is:
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.


If I run the application in the debugger and break on the exception, here is
the true stack trace (Note the exception actually occurs from

On a whim, I tried the code on .Net 2.0 Beta 1, and the Code works fine. I
don't get the ordering in the combobox I'd hoped for, but it does not throw
while data binding.
