data is not showing

[Dili1234]

I have to tables
1.[Mobilization]-Primary key is [Fen_Inovoice_No] it is the forgien key is of [invovoice details]
2.[invovoice details] the primary keys are [Fen_Inovoice_No],[Item]
when I tried to view the data , the all data are not loading to listview
why is that?

  Dim intResponse As Integer

        intResponse = MsgBox("Please insert the invoice no", MsgBoxStyle.OkOnly)

        If intResponse = vbOK Then

Try changing

[Fen_Inovoice_No]='" & TextBox1.Text & "'"

to

[Fen_Inovoice_No]=" & TextBox1.Text

Without seeing your DDL I suspect that Fen_Inovoice_No is being stored as a number, in which case you do not need the single quotes.

That's assuming of course that you've set the View property to Details

Reverend Jim what is DDL means?
tinstaafl what is the meaning of View property to Details

[Dili1234]

the Problem is only 1st data is being load to listview why is that?

[Reverend Jim]

DDL is the data definition language, or the command that you execute to create the table. An example of the DDL is

CREATE TABLE [dbo].[PDFStore](
    [FileName] [varchar](500) NOT NULL,
    [Contents] [varbinary](max) NULL,
 CONSTRAINT [PK_PDFStore] PRIMARY KEY CLUSTERED 
(
    [FileName] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

In order to display the data in a listview you have to set it to view details (columnar data)

ListView1.View = View.Details

Normally this would be done at design time. I'm assuming you have already done this. In order to display all of the records returned from the query you will need a loop. An example is

Dim dr As SqlDataReader = sqlcmd.ExecuteReader

Do While dr.Read()
    ListView1.Items.Add(New ListViewItem({rdr("Item"), rdr("Description"), rdr("Quantity"), rdr("Amount")}))
Loop
