Hi,
When we use custom filters with FilterMenuTemplate in combination with setting filters programmatically, the filter value remains visible after using the 'delete' button.
Simplified example:
- First we load a filter programmatically by the button, this works fine:
- When user uses the Delete button, the grid state loses the FilterDescriptor and we get all the data as expected (also the filter icon loses the green color, as expected because no filter is active)
- When user reopens the filter menu, the value which was loaded programmatically is still present, without being used as a filter:
Note: We have the same issue with a custom filter with a checkbox list and that code is based on the example of the filter menu template in the documentation.
Note 2: When we use the custom filters and the 'Delete' button without setting the filters programmatically, everything works fine.
It's like the 'Delete' button clears the FilterDescriptors in de Grid State (and we get the data we expect), but the FilterDescriptors in the FilterMenuTemplateContext aren't cleared.. But only when those are set programmatically.. (by setting the grid state).
I already tried to think of a workaround by hooking the OnStateChanged, but there the FilterDescriptors on the grid state are empty when the 'Delete' button is used. As expected, because we get the data we want.. But don't think I can access the FilterMenuTemplateContext there, to clear it as well..
the same problem
but we have button "Clear"
after click by "Clear" value "is true" still is visible, but filter apply correct
it is reproduce only for filter which is set in handler for OnStateInit
{
var state = new GridState<DeviceCategoryGrid>
{
FilterDescriptors = new FilterDescriptorCollection
{
new FilterDescriptor
{
Member = nameof(DeviceCategoryGrid.IsActive),
Value = true
}
}
};
args.GridState = state;
return Task.CompletedTask;
}
