error "Index was outside the bounds of the array"

[sk123]

I have a datatgrid with datasource of type Dataset (connected by SetDataBinding(ds, table_name).

Sometimes when I click on a row (uaually after resize a column or scroll the grid), I get this error message: "Index was outside the bounds of the array",
and the debugger points of the declaration of the form that starts the project.

Why is it happens and how to avoid this?

Are you running in Debug mode or Release mode?

and by the way: I'm not deleteing any row from the dataset.

Because you speak about debugger, I think you are in debug mode. Anyway debugger is often very stupid. Not always it indicates the row where error is fired. You have to look at what in the italian version you could find clicking on 'Dettagli' (I suppose Details in english version) if the button is available, if so, you can assume the last rownumber you can read (the one at the top) is the real row number where error occurs. This is only my experience, but until now it has always revealed true!
Good job!

I know what you mean, because I saw this button in many error messages before, but in this case the error message does not contain this button.

Doesn't anyone knows this datagrid problem?

[sk123]

But I still don't understand why!

it's:

Dim hi As System.Windows.Forms.DataGrid.HitTestInfo
hi = datagrid1.HitTest(e.X, e.Y)
datagrid1.CurrentRowIndex = hi.Row

I get the error after resizing a grid column, and then click any grid cell.

In fact...this is why I wrote 'if the button is available'
I saw, also that in the most of case (or always...I'm not sure ), an error occurred in a modal form, put the debbugger at ...showdialog.. line of code, not within the form. Very stupid!
Again... when you are stepping through the code ( F8 ), event routine, like FormClosing or Button.PerformClick, are executed in one shot and you can't follow their code if you don't put a breakpoint in their code. I don't know if there is some setting to change this behaviour

Anyway, I'm afraid but I have never used a datagrid, so I can't analyze your code

Good job and let's hope someone more experienced could help you, dear friend.
