Hi,

How can we customize a multiple selectable ComboBoxAdv work the same way as SfDataGrid column filter box? 

1. containing "Select All" checkbox,
2. Auto filter display content based on typing.

Thanks!

Hi Tommie,

Thank you for contacting Syncfusion support

“Query #1: containing "Select All" checkbox”

In our current implementation,we don’t have “Select All” option to select all the items

“Query #2: Auto filter display content based on typing”

In our ComboBoxAdv, there is no support for filtering content based on typing. So we suggest you to use our AutoComplete control to achieve your requirement. We have also prepared a sample

Please find the sample from the below link:

Sample link:AutoCompleteSample

In the sample we have binded items to the CustomSource of the AutoComplete

Please let us know if you need any other assistance

Regards,
M.Sugapriya

Hi,
The reason using ComboBoxAdv is that I want to keep the multiple selection option. Do autocomplete control have multiple choice? Do you have some sample to achieve this? Or do you have sample to add "select all" check box for ComboBoxAdv ?

Thank you,

Hi Tommie,

“Query: select all" check box for ComboBoxAdv?

In our current implementation, we don’t have Select All option in the control. But we have prepared a workaround which tries to meet your requirement. In this sample, we have binded IsSelected property of ComboBoxItemAdv to the ViewModel and using Select All and UnSelectAll Command we have performed selection and unselection of all the items.

Please find the sample from the below link:
Sample link:ComboBoxAdvSelectAllSample

Please let us know if you need any other assistance

Thank you so much, instead of separate buttons, I need to have "select all" check box on the top of drop down list, when user checked "all" choice, then all the check box items will be selected.
Could you kindly provide a solution to this?
