When I execute a stored procecure, I get the above error. itemImage field in the db is varchar and allow null values. I want to add value only if FileUpload1 has any file.

cmd.Parameters.Add("@itemImage", SqlDbType.VarChar, 50);

        if (FileUpload1.HasFile)
        {
            cmd.Parameters["@itemImage"].Value = txtItem.Text + System.IO.Path.GetExtension(FileUpload1.FileName);  <--------------- error here
        }

How can I solve the problem?

thanks

You are specifying a parameter without setting a value, if it's to be null if there is no file then you need to state this.  So try the following attached code
if (FileUpload1.HasFile)
{
    cmd.Parameters["@itemImage"].Value = txtItem.Text + System.IO.Path.GetExtension(FileUpload1.FileName);  <--------------- error here
}
else
{
    cmd.Parameters["@itemImage"].Value = null;
}

Have you put in your stored procedure that the itemImage parameter is nullable?

no.

if I try the follwoing with a textBox instead of FileUpload1, it works.

 if (FileUpload1.HasFile)
{
    cmd.Parameters["@itemImage"].Value = txtItem.Text;
else
{
    cmd.Parameters["@itemImage"].Value =txtItem.Text;
}

I think 'null' is acceptable.

You need to use DBNull.Value.

If you pass a .net null as the parameter value, the parameter won't be used at all, and throw the missing error.
Try doing this:

else
{
  cmd.Parameters["@itemImage"].Value = DBNull.Value;
}

That will put a "sql" null as the value.

Hello, you have to first confirm about what type of image data do you want to store the image or only its path. If you want to store the image it is compulsory to set the datatype at int and you must convert the image into binary format, after that you have to store the image into database.

or

If you want to store only path of an image. It is very easy to store set the datatype into nvarchar(max) and store the whole path of an image into it.
