Row Updating Dim f File Attachment As File Upload = CType(Me. To save the file you need to use the File Upload control’s Save As method. Get All Bytes to get its image bytes and assign it to the Sql Data Source (Update Command).
The following is an example of a Sql Data Source control where an Image parameter is added, and where the Select- and Update Command are specified (The Image parameter represents the filename that will be passed to the Update Commnad): " ID="Sql Data Source1" runat="server" Select Command="SELECT [Customer ID], [Name], [Image] FROM [Customers]" Update Command="UPDATE [Customers] SET [Name] = @Name, [Image] = @Image WHERE [Customer ID] = @original_Customer ID" The File Upload control, will not automatically save the uploaded file. I think you should put an File Uploder into the Grid View, and say that you should get the specific file through its text, and use File.
Find Control("File Upload File Attachment"), File Upload) If f File Attachment. To create a parameter that will be used by your Update Command, you can add the parameter to the data-source’s Update Parameters collection. Default Value = old End If End Sub Hope this helps...
To pass the filename that is uploaded by the File Upload control to your data-source control’s Update Command, you need to create a parameter for the filename.
Find Control("txt Number"), Text Box) Dim expiry As Text Box = Direct Cast(row.

Thanks to all you for answer, but the examples posted aren't my case.What happens with this is that the source is being created every time the user submits the page.This means that when the user does an update, the data from that update is lost. The fact that it is inside Edit Item Template means you are editing so the most likely place is at Row Updating which is the final destination before the grid commits the changes to the database. To get the instance of the control you can hook up to the Grid View’s Row Updating event. Before you can use the Save As method you need to get the instance of the File Upload control for the row you are editing.
Is it possible to place a File Upload control inside the Edit Item Template of a Grid View control? Find Control() method like I can in the Grid View_Row Data Bound event. Row Updating was meant for business validation allowing you to abort updates simply by issuing == In VB code - Private Sub Grid View1_Row Updating(By Val sender As Object, By Val e As System. The following code will get the instance of the File Upload control and save the uploaded file: protected void Grid View1_Row Updating(object sender, Grid View Update Event Args e) From the Row Updating event’s Grid View Update Event Args, you can get the index of Grid View’s row that is going to be updated.
