Help Needed...ComboBox

[kannanrs]

Hi..

How to add items to Combobox in Codebehind..

TIA

[ziomek64]

Bind items or items source I think in combobox to some collection in your code. Add items to this collection. Haven't used it but something like that perhaps. You have list of properties in docs https://mdc-maui.github.io/combo-box.

If you by any chance don't know what binding is learn that first and how mvvm works

Bind items or items source

Seems to be binding for ComboBox properties like Items and ItemsSource doesn't work at least at the actual preview version. I've tried to bind it with List<string>, ObservableCollection<string>. I've even tried to bind it with List<Material.Components.Maui.MenuItem>, used converters, etc. Nothing helped.

Tried to do it by editing the sample project from develop brunch. Same sad result, but sample project from master worked perfectly (but somehow it breaks Android build so still sad).

I am able to add items to combobox from code behind file. But You will Have to Make Observable Collection of Material.Components.Maui.MenuItem. And you will have to Add to the Items Property in combobox.

For eg there are 2 ways :
1 ) Way to add single Item through foreach loop:

foreach(var item in myCollection)
{
combobox1.Items.Add(new Material.Components.Maui.MenuItem { Text = item.PropertyName });
}

2. Way to add collection of Items by making Observable Collection.

Use Linq.

var cmbItemsCollection = new ObservableCollection<Material.Components.Maui.MenuItem>(mycollection.Select(p=> new Material.Components.Maui.MenuItem() { Text = p.PropertyName }).ToList());

//Now add the observable collection in the Combobox items :

combobox1.Items.AddRange<Material.Components.Maui.MenuItem>(cmbItemsCollection);

Adding items is done , but When there are many items, there is no scrollbar coming.
If anybody finds a way to do that, Please share.

Thank you,
