Hi, Guys

I got another problem on how to get selected value from listbox... I have a list box which displays subject names from a table. I want to get the id from the table for the subject name...

Here's my code in the get subject listing button

Code:

    DASubject.Fill(DsEduMgnt.SUBJECT)
    With lstbox
            .DataSource = DsEduMgnt.SUBJECT
            .DataTextField = "Subj_NM"
            .DataValueField = "Subj_ID"
            .DataBind()
        End With

I had try to use --> [ lstbox.Items(index).value ] to get the Subj_ID but what i get is Subj_NM .....


Do you know how to get it???

lstbox.selectedvalue, if i remember correctly

But when i use lstbox.selectvalue it return nothing....After, i see my coding one more time i realize that i forget to tell u that i have 2 listboxes which can moving item from one to another.

Here's my code in the get subject listing button (first listbox)

DASubject.Fill(DsEduMgnt.SUBJECT)
With lstbox1
.DataSource = DsEduMgnt.SUBJECT
.DataTextField = "Subj_NM"
.DataValueField = "Subj_ID"
.DataBind()
End With

After i moving the items in 1st listbox to 2nd listbox. I need to get the Subj_ID for second listbox...

here my code in the add to database button (2nd listbox)

For i = 0 To lstbox2.Items.Count - 1

Debug.Write(lstbox2.Items(i).Value)

Next

but the result return for me is the subj_NM and not the subj_ID....

in thr for loop you posted replace the .items(i) with

.SelectedItems(i).Value

hi, koncept

Did u mean like this?
If like this wil cause an error occur which is Listbox cannot be indexed because it has no default property.

For i = 0 To lstbox2.Items.Count - 1

Debug.Write(lstbox2.SelectedItem(i).Value)

Next

If u mean below the for loop will cause an error occur also which is SelectedItems not a member of listbox

For i = 0 To lstbox2.Items.Count - 1

Debug.Write(lstbox2.SelectedItems(i).Value)

Next

then im not sure...I have never used that control because i have never needed it and i never wanted users to beable to choose more than one item.

Egypt Development Blog | Get value of checked item in CheckedListBox

after bind CheckedListBox with data you can get value of checked items

Code:

For i As Integer = 0 To CheckedListBox1.CheckedItems.Count - 1
                    Dim XDRV As DataRowView = CType(CheckedListBox1.CheckedItems(i), DataRowView)
                    Dim XDR As DataRow = XDRV.Row
                    Dim XDisplayMember As String = XDR(CheckedListBox1.DisplayMember).ToString()
                    Dim XValueMember As String = XDR(CheckedListBox1.ValueMember).ToString()
                    MsgBox("DisplayMember : " & XDisplayMember & "   - ValueMember : " & XValueMember )
Next

now you can use the value or Display of checked items in CheckedListBox from the 2 variable XDisplayMember And XValueMember in the loop
