search items in Datagridview

Luc Pattyn

Your foreach loop enumerates all rows, so you will be adding a parameter (called "@id") for each of them; I don't think that is appropriate, and from your symptom description it seems the first one sticks. Suggestion: either try using the "current row" rather than all rows, or search all rows for the (first) one that actually holds some data in cell 0. :)

Don't know how it's supposed to work since you did nit tell us that. What do you expect to be in the Parameters collection? Try stepping through in the debugger and seeing if your expectations are met.

Describe exactly what you want to do after you've got the cells value in your 'id'-variable.

DaveAuld

Its not clear what you are trying to do, but the code you are using will only iterate each row, if you are trying to also iterate each cell then do the following;

        For Each row As DataGridViewRow In DataGridView.Rows
            For Each cell As DataGridViewCell In row.Cells
                'Do your necessary test etc against each cell here
            Next
        Next

You want similar behaviour on the second column? What's the name and datatype of the second column?

..and you want the same functionality in the second row cell? Something like this?

For Each row As Windows.Forms.DataGridViewRow In Me.DataGridView1.Rows()
Dim searchVal as String
searchVal = row.cell(1).value
cmd.Parameters.Add("@name", SqlDbType.NVarChar).Value = searchVal
next row

That would be flawed too, since you'd still be adding a lot of SqlParameter objects to the command. Can you post the entire method, including the parts where you create and execute the SqlCommand?

items search through storedprocedure the entire code here... Private Sub getItems() c.ConS() c.Cm.Open() For Each row As DataGridViewRow In Me.ItemsDataGridView.Rows Dim cod As Integer cod = row.Cells(0).Value Dim cmd As New SqlCommand("getItems", c.Cm) cmd.CommandType = CommandType.StoredProcedure cmd.Parameters.Add("@cod", int).Value = cod Dim da As New SqlDataAdapter da.SelectCommand = cmd da.Fill(dat) Me.bind.DataSource = dat Me.ItemsDataGridView.DataSource = bind Next row End Sub

If I understood correctly then you want to use this code to (also) filter on the "name" column? Can you post the source of the stored procedure "getItems"?

getitems()is the query which retrieves data i need to filter cod in id column . i dont know y u want see the code for stored procedure since its just a query ...... select id ,A,B,C from Items where Code =@cod :-D
