Hello Experts

I am trying to store some pattern in the database table using the data from the function which returns the dataset.

I wanted to loop through all the records from this dataset and assign the value to the stringcollection variable.

Please can someone advise how I can go about looping through the rows I get from this dataset, once I get the column values I can then assign them to the string collection.

Please see the code below, hope someone may understand what I am trying to do here?

Thanks
S

please see the code below
ds = RegistrationPersonalisedClassics.GetPatternIDAndPatternName(TemplateID)
 
 

Registration.Patterns.Add(FIRST_PATTERN_NAME_GOES_HERE + "\n" + txtPatternOne.Text)

Registration.Patterns.Add(second_PATTERN_NAME_GOES_HERE + "\n" + txtPatternTwo.Text)

Registration.Patterns.Add(third_PATTERN_NAME_GOES_HERE + "\n" + txtPatternThree.Text)

Registration.Patterns.Add(fourth_PATTERN_NAME_GOES_HERE + "\n" + txtPatternFour.Text)

Registration.Patterns.Add(fifth_PATTERN_NAME_GOES_HERE + "\n" + txtPatternFive.Text)

Registration.Patterns.Add(sixth_PATTERN_NAME_GOES_HERE + "\n" + txtPatternSix.Text)
 
 
 
 

Public Shared Function GetPatternIDAndPatternName(ByVal TemplatedID As Integer) As DataSet
 

        

        Dim dt As New Data.DataTable("Pattterns")

        Dim dr As Data.DataRow

        Dim dbConn As SqlConnection

        Dim SQL As String

        Dim dbComm As SqlCommand

        Dim dbRead As SqlDataReader
 
 

        Try

                        dbConn.Open()

            SQL = "SELECT * " & _

                  "FROM PC_Pattern " & _

                  "WHERE TemplateID=" & TemplatedID
 

            dbComm = New SqlCommand(SQL, dbConn)

            dbRead = dbComm.ExecuteReader()
 

            dt.Columns.Add(New DataColumn("PatternID", GetType(Integer)))

            dt.Columns.Add(New DataColumn("PatternName", GetType(String)))

           

            While dbRead.Read

                dr = dt.NewRow

                dr.Item("PatternID") = dbRead("PatternID")

                dr.Item("PatternName") = dbRead("PatternName")

                dt.Rows.Add(dr)

            End While
 

            ds.Tables.Add(dt)
 

            Return ds

        Catch ex As Exception

            Return Nothing

        End Try

    End Function

Here is an example of looping through the dataset.


For i as integer = 0 to dSet.Tables(0).Rows.Count - 1

    str &= "Name: " & dSet.Tables(0).Rows(i).Item(0) & ", Address: " & dSet.Tables(0).Rows(i).Item(1) & VBCRLF

Next
