Hi,

The solution didn't worked.  With the fixed you provided the data in combo box was not populating.

The issue i occurred is that when using the XamComboEditor by selecting the values in drop-down using the mouse the already selected value from drop-down is disabled when selecting other values from drop-down

But now the issue is that by selecting the value of the drop-down using the keyboard from drop down the already selected is not disabled despite the value is selected in previous combo box.

Elaborate description is attached in screenshot.

Hello Mayank,

In order to reproduce the behavior you have reported, is necessary to provide the code behind of the XAML you have sent and the implementation of the events used – for example the XamComboEditor ValueChanged handler, selection handlers if used and etc. It will be useful if you provide the code that disables the selected combo item.

Sincerely,

Code behind file: Xaml.cs code

private void OnValueChanged(object sender, RoutedPropertyChangedEventArgs<object> e)

{
ValueEditor editor = (ValueEditor)e.OriginalSource;
CellValuePresenter cvp = (CellValuePresenter)editor.Host;
cvp.Value = editor.Value;
RecordPresenter presenter = RecordPresenter.FromRecord(cvp.Record);
if (presenter != null)
{
if (underWritinInfoNameSSNViewSE != null)
{
if ((Convert.ToString(cvp.Value).Contains(ViewModelConstants.SINGLE_HYPHEN_WITHOUT_SPACE) &&
Convert.ToString(cvp.Value).Length >= 13)
||
(!Convert.ToString(cvp.Value).Contains(ViewModelConstants.SINGLE_HYPHEN_WITHOUT_SPACE) &&
Convert.ToString(cvp.Value).Length >= 12))
underWritinInfoNameSSNViewSE.UpdateSSNAndName(cvp.Record.DataItem, e.OldValue);
string tempNewValue = Utilities.RemoveHyphen(Convert.ToString(e.NewValue));
string tempOldValue = Utilities.RemoveHyphen(Convert.ToString(e.OldValue));
if ((!string.IsNullOrEmpty(Convert.ToString(tempNewValue))
&& tempNewValue.Length != 12) || (string.IsNullOrEmpty(Convert.ToString(tempNewValue))
&& tempNewValue.Length == 0))
{
underWritinInfoNameSSNViewSE.EnableSSNOnRemoving(tempNewValue, tempOldValue);
}
}
}
}

Hello Mayank,

Which version of the product do you use in your application?

Sincerely,

InfragisticsWPF4.v14.1

Version: 14.1.20141.1015

Hello Mayank,

In order to investigate the behavior further I would need to reproduce the issue. To do that, please provide a sample that demonstrates the described scenario.

Having this information would help me further investigate this matter for you.

Let me know if you have any questions or concerns.

The issue is still existing. The second number in drop down is disabled which is correct. But the issue occurs when we have entered the first number in first combobox and then we can enter the same number in second combobox as well. The number once entered should not be entered in the other dropdowns. 

Hello Mayank,

Is the issue with the keyboard selection reproducible on your side when running the ComboItemWorkaround sample application I have attached in my previous response? If that is so, could you please have a look at my environment details and steps to reproduce and let me know if there is any difference?

Environment details:

- Infragistics WPF 14.1.20141.1015

- Visual Studio 2015, Update 2;

- Windows 8.1;

Testing steps:

1. Click on the combo editor input area

2. Navigate through the items using the keyboard up and down arrows

Please note that in order to investigate the behavior further I would need to reproduce the issue. Feel free to share any details that are related to your environment and implementation and will be helpful in replicating the behavior.

Let me know if you have any questions or concerns.

Hi,

Can you please look into this as it is still not working for me.

Hello Mayank,

I have created a sample application based on the approaches from the forum threads that I have provided in my previous post and it seems to work on my side.

If you still experience the issue, would you please modify the sample with the functionality that you are using, so it reproduces the issue?

This way I would be able to further investigate this for you and provide you with more detailed information on this matter.

Sincerely,
