This is a variation on a question I asked earlier.
I have a SQLDataSource1 and a InsertParameter called AttachmentData of type "DBType=Binary".
I want to load the parameter from a Byte array called Buffer. Dim Buffer as Byte().
this works from inside an Inserting event:
e.command.parameters("@AttachmentData").value = Buffer
But I need to do it from a prior event so I'm trying this.
SQLDataSource1.InsertParameters("AttachmentData").defaultvalue = Buffer
It gives the error:
Value of type "1-dimensional array of Byte' cannot be converted to 'String'.
What can I do?

Hi DaveBF3
DaveBF3 SQLDataSource1.InsertParameters("AttachmentData").defaultvalue = Buffer
SqlDataSource1.InsertParameters("AttachmentData").DefaultValue need type of string, but the Buffer is a byte array. You could only enter string type value to the DefaultValue.
DefaultValue: https://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.parameter.defaultvalue(v=vs.110).aspx
