what have you tried so far?

How do you interpret 'read-only' in the context of 'combo-box'?

CHill60 3-Jun-15 7:02am

Good point - you can still select the items :)

I think this is pure case of RTFM...

Solution 1

You need to include an item "Test input" and set IsSelected="True" e.g.

XML

<ComboBox IsEditable="False" >
    <ComboBoxItem IsSelected="True">
        Test Input
    </ComboBoxItem>
</ComboBox>

I don't need to include the content into the list item

Well that is how you display text in a combo-box in WPF. If you only want to display some text use a TextBlock instead. Both KEP and I are interested in what you mean by a 'read-only' combobox

I have a Combo box, and its IsEditable="Falase". also it contain some list items.
I need to set a default value in combo box and it should display as the default of the UI load, and not include the default value in combo box list item.

You may need to "insert" some text, but this sounds a little weird to be honest. You might be better off trying explain (in detail) what you are trying to achieve from your "users" perspective. Are you trying to do something like "Choose a Value" being displayed, then then "choose a value" is not a valid selection?

Member 11603144 16-Jun-15 2:14am

for eg: i have a combobox with dropdown contains 3 values"small","large","medium".
When i load the UI the comboxbox should contain a text "Select size"

Ok - that changes things a little bit. Post the XAML for the combo-box and I'll have another look

Member 11603144 17-Jun-15 0:18am

<combobox x:name="cmbOffsetType" height="22" width="110" x:uid="cmbOffsetType" selectedvaluepath="ID" selectedvalue="{Binding P5XVMList[0].OffsetType, ValidatesOnDataErrors=True, UpdateSourceTrigger=PropertyChanged}" itemssource="{Binding OffsetType}" displaymemberpath="Value" verticalalignment="Top" horizontalalignment="Left" grid.column="5" grid.row="1">

Edit - from CHill60 - the code IS here just not displaying - I used Edit Comment to grab it

I haven't got time to sort out all of the syntax errors in the xaml you posted so I've added some links to alternative solutions to my post above.
