Create a new data control in vb.net, late binding

Is there, or can I create a new control that acts much like the vb6 COM data control that allows me to drop the control on a form and set late binding to a table or query in a MS Access database? Thanks, Mike

Hi Mike, My WinForms is a bit rusty, but I'm pretty sure binding to a DataGridView with a DataSet etc will automatically generate columns for you at runtime based on the data you give it. Hope that helps,

Hi James, I'm upgrading a large vb6 vertical market program to vb.net. In that program I used the data control (ADO) and set all connection parameters in code, then assigned text boxes datasource as the ADO data control. A very simple process. I don't want to use the data sources provided by the IDE, I would rather have a data control that I can instantiate at run time instead of creating all these connections (which seems to really slow the system down) in development. Any ideas? Mike

Hi Mike, I might be missing something here, but there shouldn't be anything to stop you from creating these datasources at runtime rather than design-time if that's what you want to do? You can set the DataSource of the control to whatever you like in your initialization code....

James, I'm using OLEDB connection and adapters that create a dataset and I'm populating fields as advertised. Is there a way you can show me in code (without using Wizards) how to create the data connections in the IDE. If I continue doing what I'm doing there will be hundreds of Data Sets in the IDE which will slowwwwww.... this sucker down quite a bit. Any thoughts, Mike
