Bind property of view model to IsHidden via converter

[Thomas Schmid]

Hello,

the data object in the ObservableCollection of my view model is

class Data
{
public bool IsEnabled{ get; private set;}
public float Value{get; set; }
...
}

In my view I have inside the SfDataGrid (I had to use the "(" instaed of "<" since "<" row were deleted)
(syncfusion:SfDataGrid
  ItemsSource="{Binding Source={StaticResource cvsData}}"
  ...
  >
  (syncfusion:SfDataGridColumns> 
    ...
    (syncfusion:GridNumericColumn
      HeaderText="Value"
      DisplayBinding="{Binding Value}"
      IsHidden="{Binding IsEnabled, Source={StaticResource cvsData}, Converter=BoolConverterNOT}"
      ...
      />

The converter negates the IsEnabled flag. The value "Value" is shown, but the IsEnabled-flag is not respected. Is there an error in binding?

Hi Thomas, 

Please find the response for your queries, 

Query 1 : In my view I have inside the SfDataGrid (I had to use the "(" instaed of "<" since "<" row were deleted)

We didn’t know how to used the “(“ in your application kindly revert to us with modified sample based on your application that will be helpful to provide appropriate solution at the earliest.

Query 2: The converter negates the IsEnabled flag. The value "Value" is shown, but the IsEnabled-flag is not respected. Is there an error in binding?

We had prepared the sample based on your given code snippet but IsHidden is set properly  based on ViewModel property value. For your reference we had attached the sample in below mentioned location.  Sample location: http://www.syncfusion.com/downloads/support/directtrac/general/ze/SfDataGridDemo-1596816084  Please refer the below UG link for more details about IsHidden property.  https://help.syncfusion.com/wpf/sfdatagrid/column-types#hide-column  Please refer the below KB links for more details about your requirement.  https://www.syncfusion.com/kb/2476/how-to-bind-the-gridcolumn-ishidden-property-to-property-in-viewmodel  If your requirement  is different from above kindly revert to us with more details about your requirement like modified sample, video or screenshot illustration that will be helpful to provide appropriate solution at the earliest.

1) When I used the "<" char at the beginning of a xml string, the complete row was deleted after saving (therefor I edited the request about 5 times and at least I used the "(" char).

2) I found the error, just a stupid one:

  IsHidden="{Binding IsEnabled, Source={StaticResource cvsData}, Converter={StaticResource BoolConverterNOT}}"
