    <p>I am trying to import a .csv file into my database. I am able to import an excel worksheet into my database, however due to different file format as .csv as from .xls, I need to make an import function specially for .csv.</p> <p>Below is my code:</p> <pre><code>protected void Button1_Click(object sender, EventArgs e) { if (FileUpload1.HasFile) { // Get the name of the Excel spreadsheet to upload. string strFileName = Server.HtmlEncode(FileUpload1.FileName); // Get the extension of the Excel spreadsheet. string strExtension = Path.GetExtension(strFileName); // Validate the file extension. if (strExtension != ".xls" &amp;&amp; strExtension != ".xlsx" &amp;&amp; strExtension != ".csv" &amp;&amp; strExtension != ".csv") { Response.Write("&lt;script&gt;alert('Failed to import DEM Conflicting Role Datasheet. Cause: Invalid Excel file.');&lt;/script&gt;"); return; } // Generate the file name to save. string strUploadFileName = @"C:\Documents and Settings\rhlim\My Documents\Visual Studio 2005\WebSites\SoD\UploadFiles\" + DateTime.Now.ToString("yyyyMMddHHmmss") + strExtension; // Save the Excel spreadsheet on server. FileUpload1.SaveAs(strUploadFileName); // Create Connection to Excel Workbook string connStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + strUploadFileName + ";Extended Properties=Text;"; using (OleDbConnection ExcelConnection = new OleDbConnection(connStr)){ OleDbCommand ExcelCommand = new OleDbCommand("SELECT [columns] FROM +userrolelist", ExcelConnection); OleDbDataAdapter ExcelAdapter = new OleDbDataAdapter(ExcelCommand); ExcelConnection.Open(); using (DbDataReader dr = ExcelCommand.ExecuteReader()) { // SQL Server Connection String string sqlConnectionString = "Data Source=&lt;IP&gt;;Initial Catalog=&lt;DB&gt;;User ID=&lt;userid&gt;;Password=&lt;password&gt;"; // Bulk Copy to SQL Server using (SqlBulkCopy bulkCopy = new SqlBulkCopy(sqlConnectionString)) { bulkCopy.DestinationTableName = "DEMUserRoles"; bulkCopy.WriteToServer(dr); Response.Write("&lt;script&gt;alert('DEM User Data imported');&lt;/script&gt;"); } } } } else Response.Write("&lt;script&gt;alert('Failed to import DEM User Roles Data. Cause: No file found.');&lt;/script&gt;"); </code></pre> <p>}</p> <p>The file has been successfully saved, but the error says that the path for the file is not valid, even though the file has been successfully saved as .csv, therefore I am not able to continue with the process of importing the data into my database.</p> <p>Below are the screenshots of my error: <img src="https://i.stack.imgur.com/gwGnJ.png" alt="enter image description here"> <img src="https://i.stack.imgur.com/Lxlfl.png" alt="enter image description here"></p> <p>In conclusion I am having the error that the file path which the csv file is saved is not valid, although the csv file is successfully saved. Need some help from experienced. Thank You</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
