Datagrid and money format problems (BUG?)

[Tamlin]

Hi all,

I'm getting a bug with the datagrid object.
I've created one from scratch, bound it to a dataview with 2 int32
columns and formatted the output as currency.

I've found that when you use the F2 key to enter edit mode and then
hit TAB or ESCAPE without actually editing the value, dotnet crashes
with a null reference error.

Any takers?

To replicate this problem, create a new form, add a datagrid and add a
tablestyle with two columns, mapping to col1 and col2.
Set the format of col1 to "c" and put this in the constuctor:

DataTable loTable = new DataTable();
loTable.Columns .Add("col1", typeof(Int32));
loTable.Columns .Add("col2", typeof(Int32));

this.dataGrid1. DataSource = loTable.Default View;
loTable.Rows.Ad d(loTable.NewRo w());
loTable.Rows[0]["col1"] = 1234;
loTable.Rows[0]["col2"] = 5678;

Run it, and hit F2 on the first cell, and then TAB.

I've also noticed that it won't crash if there's only one column.

Please help!
Thanks,
Tamlin Cowgill

Tamlin,

I could not reproduce your problem. I have installed the sp1 for Net 1.1

It must be something else, I've just installed SP 1 for .Net FWK 1.1
this morning and I'm still getting the same problems.

Can anybody else replicate this problem?

I'm using:
Microsoft Development Environment 2003, Version 7.1.3088
Microsoft .Net Framework 1.1 Version 1.1.4322 SP1
Microsoft Windows 2000 SP4
I also had VSIP installed but have since had it removed.
Here's the entire form code:
