Hi,

Regarding SfComboBox, How do I know selectionchange happened because user interaction, not from programmatic binding updates?

TIA

Hi Diego,

 

Thanks for sharing the details. To assist us in investigating this further, could you please clarify the purpose of identifying whether the selection change in SfComboBox is triggered by user interaction or by a programmatic update? This will help us provide an appropriate solution

 

Best regards,

Hi,

Scenario:

Product 1 - Color: Blue, Size 1
Product 2 - Color: Blue, Size 2
Product 3 - Color: Blue, Size 3
Product 4 - Color: Red, Size 2
Product 5 - Color: Red, Size 3
Product 6 - Color: Red, Size 4

Combo1 - Blue/Red
Combo 2 - 1/2/3 or 2/3/4, depending on current visible product

When I change selectionvalue, it must show the correct product image.

Regards,

Diego

Hi,

I've modified your example.

6 products, 2 colors, 3 sizes. Changing colors, sizes combo must changed items source. And set a valid size.

Both combos must be set from buttons as well.

Hi Diego,

 

Thank you for providing the modified sample. We were unable to clearly determine your exact requirement from the current implementation. Could you please clarify the specific behavior or outcome you are expecting? For your reference, we have attached a demo video demonstrating the observed behavior.

 

Best regards,
