    viewFile and downloadFile running forever...

    Hi, I am using SmartClient 11.0p 17-03-29 with MSSQL 2012.
    I have successfully uploaded files to SQL server usning multiFileItem as instructed in the example.
    However when I click the view icon or download icon from the multFile control. It never responde and server hangs.
    When I looked at the RPC response in the console it say [Request in Progress].
    I have also tried jtds driver as someone said he solved with the driver but no luck for me.
    Please anybody help me on this.

    This is the table I created.
    CREATE TABLE [dbo].[c004_ssc_activity_files](
    [id] [int] IDENTITY(1,1) NOT NULL,
    [contents_filename] [nvarchar](255) NULL,
    [contents_filesize] [numeric](10, 0) NULL,
    [contents_date_created] [datetime] NULL,
    [activity_id] [int] NULL,
    [contents] [varbinary](max) NULL,
    CONSTRAINT [PK_c004_ssc_activity_files] PRIMARY KEY CLUSTERED
    (
    [id] ASC
    )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
    ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]


    And this is the datasource,
    <DataSource
    schema="dbo"
    serverType="sql"
    dbName="SmartOffice"
    ID="c004_ssc_activity_files"
    tableName="c004_ssc_activity_files"
    >
    <fields>
    <field name="id" type="sequence" hidden="true" primaryKey="true" implicitSequence="true"></field>
    <field name="activity_id" type="integer" foreignKey="c000_ssc_activities.id" hidden="true"></field>
    <field name="contents" type="binary"></field>

    </fields>

    </DataSource>

    The server log is like this,

    First check your client-side Developer Console and report what's there - you should always do this.

    Check with multiple browsers and report whether this a browser-specific problem, and disable extensions in any browsers where there's an issue (this also you should always do).

    You can also check that the file is present and intact via direct SQL access. Also check with the browser built-in developer tools to see whether any data was transferred, and whether HTTP headers such as Content-Type and Content-Length seem to be set correctly.

      I have found that the file "contents" is not saved in the database whereas other fields(contents_filename, etc) are stored correctly.
      Is there any common mistake which causes contents are not saved?

        We just explained all the things you should examine and post when you have an issue, so same thing, but now examine why your upload is failing.
