Sort using DictionaryOf(string, String)

[DavidBS]

Hi !

I set my SfCombo using a dictionary of strings as shown below:

comboGrupos.DataSource = New BindingSource(Grupos, Nothing)
comboGrupos.DisplayMember = "Key"

comboGrupos.ValueMember = "Value"

When I try to sort it using

comboGrupos.DropDownListView.View.SortDescriptors.Add(New Syncfusion.DataSource.SortDescriptor() With {.PropertyName = "Key", .Direction = Syncfusion.DataSource.ListSortDirection.Ascending})


I receive an error:

System.InvalidOperationException  HResult=0x80131509  Message=There is no coertion operation defined between types 'System.Collections.Generic.KeyValuePair`2[System.String,System.String]' and  'System.String'. Source=System.Core  

Is there any way to sort this combo using its "DisplayMember" value (field KEY)?

Thanks!

Hi David, 

 

Greetings from Syncfusion. 

 

We have checked your reported query “Sort using DictionaryOf(string, String)” and we would like to let you know that we can able to Sort while using Dictionary of strings in SFComboBox dropdown items by using SortedDictionary.We have prepared the sample to sort the SFComboBox dropdown items in ascending and descending orders.  

 

Code snippet 

 

'Acending order 

Dim My_dict1 As New SortedDictionary(Of String, String)() 

 

 

'Decending order 

Dim My_dict1 As New SortedDictionary(Of String, String)(New Form1.DescendingComparer(Of String)())
