I'm having some trouble setting up binding sources to these types of files, not sure if I'm selecting the correct driver in the wizard. Tried the generic ODBC and .NET drivers but it doesn't work, the dataset is created and adds a table but there's no data retrieved. The design object being used to display the table is a datagridview. Can't find documentation on dealing with files, only databases.

I have a form that has three comboboxes in it, cbxStudy, cbxMethod, & cbxAnalyte. When I call the form I load a data table and use that table to fill the comboboxes. I want to assign a value to cbxStudy, then fill cbxMethod by filtering the data table using the value in cbxStudy, then fill cbxAnalyte by filtering the data table using the values in cbxStudy and cbxMethod.
This code keeps failing when the forms New constructor is called, but once the form is loaded the code works great. I indicated below where the code is failing. It's failing because Me.cbxStudy.SelectedValue is = {System.Data.DataRowView} when the constructor is called even though I set the SelectedValue myself.

View 7 RepliesIs it better to add just one datasource to your project that holds all your database tables and queries that you use as typed datasets. Or, create a datasource for each individual form or situation where your using the database tables as typed datasets. It seems simplier to have just one datasource but is there a down side. We're talking about @25 database tables/queries.

I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.
