Re: Accessing data based on grid selected row

[Ilya Tumanov [MS]]

I've noticed VB developers tend to (over/miss) use message boxes a lot
without realizing they drive users completely insane.

You can not copy data from them and you have to push the button every time
it pops up - absolutely terrible.

In this case it's probably way better to add a "Description" tab with big
message box for description and bind it to the same data view so it would be
updated automatically.

Anyway, if you'd like to carry out your original message box idea, here's
how to access selected row:

dataView(dataGrid.CurrentRowIndex)("ColumNameOrIndex")

In this case the description will rarely be needed. The screen space taken
by the tabs won't be worth it.

Anyway, I had already tried what I think is the C# equivalent to what you
suggested:
dataRow = dataView.Table.Rows[dataGrid.CurrentRowIndex]

But my problem was that dataRow was assigned the row indexed by the DataSet,
once I applied a filter and sort to dataView, the results returned were
incorrect.

Anyway, I 'solved' the problem by adding a 0-width description column to the
grid.

Thanks,

Rob

No, that is not the equivalent. Your code would access rows in DataTable
disregarding DataView.

And you're correct; row index in DataTable can be different from row index
in DataView due to sorting and filtering.

Here's how to get correct DataRow:

dataRow = dataView[dataGrid.CurrentRowIndex].Row;
