Uploading files asp net c#
Next, we need to create a new Webform. This is where the fun begins. In order to solve this, the extra button is provided. Your mark-up for the two controls should look like:. View All. Michael Griffiths Updated date Jun 20, In order to work with the Picture and BrochurePath properties, we need to first add them to the CategoriesDataTable and then update the CategoriesTableAdapter class to return these columns.
Start by adding these two columns to the CategoriesDataTable. Right-click on the CategoriesDataTable s header, select Add from the context menu and then choose the Column option. Rename this column to Picture. Byte[] this is not an option in the drop-down list; you need to type it in. Byte[] Click to view full-size image. We could have both of these column values returned in the main TableAdapter query, but this would bring back the binary data every time the GetCategories method was invoked.
Instead, let s update the main TableAdapter query to bring back BrochurePath and create an additional data retrieval method that returns a particular category s Picture column. To update the main TableAdapter query, right-click on the CategoriesTableAdapter s header and choose the Configure option from the context menu. This brings up the Table Adapter Configuration Wizard, which we ve seen in a number of past tutorials.
Update the query to bring back the BrochurePath and click Finish. However, it also updated the column list in the GetCategoriesAndNumberOfProducts method, removing the subquery that returns the number of products for each category! Next, create a new TableAdapter method that returns a particular category s Picture column value. The first step of this wizard asks us if we want to query data using an ad-hoc SQL statement, a new stored procedure, or an existing one. The last step is to choose the name for the new method.
Click Finish to complete the wizard. After completing the Table Adapter Query Configuration Wizard you may see a dialog box informing you that the new command text returns data with schema different from the schema of the main query. In short, the wizard is noting that the TableAdapter s main query GetCategories returns a different schema than the one we just created.
But this is what we want, so you can disregard this message. You will have to manually update the column list to return the Picture column, similar to what we did with the GetCategoriesAndNumberOfProducts method earlier in this step.
Add the following method to the CategoriesBLL class:. When collecting binary data, oftentimes this data is supplied by an end user. To capture this information, the user needs to be able to upload a file from their computer to the web server. The uploaded data then needs to be integrated with the data model, which may mean saving the file to the web server s file system and adding a path to the file in the database, or writing the binary contents directly into the database. In this step we'll look at how to allow a user to upload files from their computer to the server.
In the next tutorial we'll turn our attention to integrating the uploaded file with data model. Clicking the Browse button brings up a dialog box from which the user can select a file. When the form is posted back, the selected file s contents are sent along with the postback. On the server-side, information about the uploaded file is accessible through the FileUpload control s properties. To demonstrate uploading files, open the FileUpload.
NET Page Click to view full-size image. Figure 13 shows this page when viewed through a browser. Note that clicking the Browse button brings up a file selection dialog box, allowing the user to pick a file from their computer.

On postback, the uploaded file can be saved to the file system or its binary data can be worked with directly through a Stream. Start by adding the Brochures folder to the site as a subfolder of the root directory.
Next, create an event handler for the UploadButton s Click event and add the following code:. The FileUpload control provides a variety of properties for working with the uploaded data. In this article I will explain with an example, how to upload file in ASP. HTML Markup. Net FileUpload control, a Button and a Label control.
