How to view data from a table with multiple rows
Posted on 2012-12-25
I am using the code below to view countries in a table. How do I modify the code to use a next button to see all the countries in the table? The code below only displays the first record.
For Each xnDonor As Xml.XmlNode In xdDonor.SelectNodes("/Root
DonorID2 = xnDonor.SelectSingleNode("
Name = xnDonor.SelectSingleNode("
dtDonor.Rows.Add({DonorID2
Next
C1CountryOrigin.Text = dtDonor.Rows(0).Item("Coun
Thanks,
Victor

I assume C1CountryOrigin is a label or textbox, so to list all the records you will need to convert the values to a string.
on the other hand, if you want to display them in a combobox, simply set its datasource to the datatable, e.g ComboBox1.DataSource = dtDonor (you may want to set the DisplayMember and the value Member if you choose this route).
In the same way, if you want to display the rows in a datagrid (or even datagridview), simply set its datasource to the datatable, e.g DataGridView1.DataSource = dtDonor (in this case the columns will be autogenerated from the datatable)

Hi,
C1CountryOrigin is a textbox, I need to see the data in the next row when I click on a Next button. What code do I use to see data in each fow?

declare a class wide integer variable as
Dim MyRowIndex As Integer = 0
MyRowIndex = if(MyRowIndex < dtDonor.Rows.Count - 1, MyRowIndex + 1, MyRowIndex)
C1CountryOrigin.Text = dtDonor.Rows(MyRowIndex).Item("Country")
MyRowIndex = if(MyRowIndex = 0 , 0, MyRowIndex - 1)
C1CountryOrigin.Text = dtDonor.Rows(MyRowIndex).Item("Country")
