Howto return the currentvalue from a datagrid (Silly question...)

[RedLion]

It’s a very silly question, but I can’t get it to work, and I can’t find a solution now I need it. Yes I can get it to work in VB.NET (using the items collector, but C# doesn’t have it…), but in C# it won’t work…

I have pasted a DataTable from a DataSet to a DataGrid.

When someone double clicks a row within a DataGrid I would like to return a value from the column path within the DataTable. So I do the following:

return ((DataTable)grdResult.DataSource).Rows[grdResult.CurrentRowIndex][1].ToString();

And then I got the following error:

error: object '(DataTable)grdResult.DataSource.Rows' doesn't have an indexer

What stupid mistake have I made?

Thanks!

try referencing the value in the cell:

return grdResult[grdResult.CurrentRowIndex, 0].ToString();

this will return the value in the first cell of the current row.

int iActiveCellRow=grdResult.ActiveRow.Index;
and iActiveCellRow maps to yourDataTable.Rows[ index]

Thanks for the responses, I will go and try it.

But still the question, isn't it possible to access a field in a DataTable by just referencing a DataTable?

return myDataTable.Rows[0]["path"].toString();

or something like that?

yes u can,i thought you wanted the cuurent row and cell values

Yes chmohan, you're right, but because it didn't work in the first try out, I tried a couple of things, and one was

return myDataTable.Rows[0]["path"].toString();

and that resulted in the error that "doesn't have an indexer" on the "Rows" object, so I was curious if it's possible or not? But the code example doesn't work here because the exception says that "Rows[0]" may not be done...

Any inside information I'm not aware of???
(That's the reason for mine second question)

try getting the rows.count and see
also you may try Rows[0][0].ToString() to see if u can get the first columsn value
