programmatically set the SelectedItems for a ListBox

[tommcd24]

Hello all,

I need a way to read a previously saved list of customers and
programatically "Select" these items in an existing listbox. Something
to the effect of ListBox.Selecte dItems = myCollection. Of course
SelectedItems is readonly.

I'm reading in from an XML file and I have that portion of the issue
resolved. Where I run into problems is how to get them all selected.

Any suggestions?

Thanks Armin,

SetSelected wants an index and I'm difficulty translating the values
from my xml file which correspond to the ValueMember property of the
listbox items. I've looked into ListBox.FindStr ing() and
ListBox.IndexOf () but both return -1. I'm guessing they must be
searching the DisplayMember property.

Any thoughts on how to translate from the ValueMember values to Index?

Does anyone have suggestions or sample code to do this? I need to be
able to Select listbox items based on the item value.

Thanks in advance,

I don't know if you're looking for a routine below or not to set the combox
to the display is display value based based on its item value or not, but it
might help you, possibly.


Sub SelectCBOBbyIte m(ctrl as Combobox, someval as whatevertype)

dim i as Integer
For i = 0 To ComboBox1.Items .Count - 1

ComboBox1.Selec tedIndex = i

If ComboBox1.Selec tedValue = someval Then exit sub

Next

end sub

Oops, you would be using the ctrl

call SelectCBOBbyIte m(Combox1, value)

Sub SelectCBOBbyIte m(ctrl as Combobox, someval as whatevertype)

dim i as Integer
For i = 0 To ctrl.Items.Coun t - 1

ctrl.SelectedIn dex = i

If ctrl.SelectedVa lue = someval Then exit sub

Next

end sub

Re: programmaticall y set the SelectedItems for a ListBox

I was overcomplicatin g this issue. I was assuming that
ListBox.Selecte dValue could only hold 1 value. On a lark I tried
repeated calls using that property and achieved the result I needed of
selecting multiple items based on the ValueMember. I'm including my
code below for others who may have similar situations.

Using xReader As XmlReader = XmlReader.Creat e(strFilePath & "\"
& strFileName)
xReader.ReadSta rtElement("Cust omers")
While xReader.Read()
If (xReader.IsStar tElement()) Then
If (xReader.IsEmpt yElement()) Then
Me.lstCustomers .SelectedValue = xReader(0)
End If
End If
End While
End Using
