I'm having some trouble trying to export a datatable to Access. I've built an Access DB and Table identical to the datatable that I'm trying to export using ADOX.Now using and OLEDB connection I'm trying to populate that table. The following code works just fine in another app written in 2005 but not in 2008 for some reason.
Basically I'm bringing in the empty Access table into a dataset.Filling that table with the rows from the export datatable.Then running the dataadapter's update method to send the data to Access.The problem is the da_a.Update doesn't seem to work. No errors, the Access table just isn't being populated. I checked my before and after counts. I know that the datatable is being populated. It's just not landing in Access.

I have a datagridview bound to a datatable setting its datasource property to the datatable. I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)
now I would like save these visible columns on some event like form_closing so that the next time the user opens the form up it will remember the settings
I came across a problem with using a BindingSource as my DataGridViews.DataSource. Whenever I applied a filter to a column in the BindingSource and the user makes changes that don't match the column filter the DataGridViewRows would automatically disappear. A similar thing would happen when applying a Sort to a column. If the user made any changes the DridGirdViewRows would automatically sort causing rows to be moved around. This was not ideal for my application and there isn't anyway to stop this from happening with the BindingSource.
To correct this issue I have to use subsets of data. I use a DataView to apply the filter and sort to the main DataTable, which creates the subset DataTable.The problem is when I use the DataView.ToTable method I loose the Primary Key and RowError information. So I have to reapply this information everytime the user filters or sorts the DataGridView.Is there a better way to get a subset DataTable?[code]...
