Combo value null - binding problem

405

Andrew Cronwright posted over 11 years ago

I'm using version 11.2 I have an UltraCombo bound to an underlying business object. I have allowed nulls on the combo. When a value combo is selected from the combo, it updates the underlying business object's property that it is bound to. When the value is cleared, the combo does not set the underlying business object property to nothing. This worked in previous versions of Infragistics. I've created and attached a test solution to highlight this problem.

Hi,

I tried running your sample and I played around with a little bit, but I don't see any problem here like what you describe. What, exactly, do I need to do with this sample to see the problem?

Hi Mike. I've attached a video with the problem. When the combo is set to a value from the dropdown, the value selected is written to the output window. However when the value is cleared the property set is never called and nothing is written to the output window (I'm expecting zero to be written to the output window)

The Infragistics version I'm using is 11.2.20112.2050

I have now discovered that this seems to be specific to Windows 8. On Windows 7 it works as is expected.

Hello,

I tried your sample with service release 2135 which is the latest for v11.2 and it worked fine for me in both Win7x64 and Win8x64. I can see that it does not work in 11.2.2050, so we have fixed this.

Could you please download this release(2135) and test your application against it. You could do so from https://es.infragistics.com/my-account/keys-and-downloads/, then please click on 11.2 version and then on the 'Service Releases' tab.

Let me know if you face any issues.

Hi Leo,

I tested the sample provided above and it appears that the underlying data is being updated correctly. Please provide a sample application that reproduces this issue and I will continue to investigate. If you would prefer not to upload your sample to the public forum, please let me know and I will open a private support case for you.

Hello. I'm having this issue with version 17.1.20171.1008. When the combo is bound to an object, if I clear the combo (removing all characters) the underlying value does not get updated and I cannot even move out of the combo control (the cursor stays in the control and I cannot click nor tab anywhere else). I'm using an UltraCombo (not UltraComboEditor)
