Hello,

This is related to https://www.telerik.com/forums/samplingunit-of-none-does-not-disable-sampling, but I think a bit more specific of an issue.

I enable Data Sampling with a DateTime-based series by applying a ChartDataSourceStyle. Once I do this, sampling is always applied, even if my threshold allows all data points to be shown - it still goes through to sampling process.

I tried setting the ChartDataSourceStyle to null, expecting sampling to be disabled, but instead the previously-used sampling settings remained applied.  For instance, I may have my sampling set to a 5-minute interval, then when I zoom in to a small enough range to set the ChartDataSourceStyle to null, and my data remains sampled at 5-minute intervals.

When profiling my application, it appears that ChartSeriesDescriptor.OnChartDataSourceStyleChanged() ignores a change to a null style, and leaves the series descriptor bindings unchanged.  However, ChartSeriesDescriptor.BindItemsSource() does include a check for a null style, and if so binds directly to the ChartSeries rather than the ChartDataSource. Should the null check in ChartSeriesDescriptor.OnChartDataSourceStyleChanged() be removed?

Thanks,

Brandon

Hello,

how would I go about if I wanted the RadAutoCompleteBox to show all items if the SearchText is empty instead of no items at all?

I had my desired behaviour already implemented using the RadComboBox, which was perfectly fine, despite the fact that I'm dealing with mutliple thousands of items easily and the AutoCompleteBox seems to deal with those amounts of items better than the ComboBox.

What I want is a AutoComplete box that opens upon getting the focus (or upon pressing Ctrl + Space). If the SearchText is populated I want the dropdown to contain the filtered list. But if the SearchText is empty I want the dropdown to show all the entries. Currently it shows none.

To open the dropdown on focus and on ctrl+space is not the problem. Only the contents of the dropdown.

I found guides for silverlight (https://www.telerik.com/forums/display-all-items-on-focus) aswell asp.net (https://www.telerik.com/support/kb/aspnet-ajax/autocompletebox/details/show-all-records-when-focusing-the-input-element-of-autocompletebox) but was not able to adept those solutions fopr WPF.

Hello,

I had made a custom filter in unbound mode for some properties. Boolean properties and enum properties works well, but im trying to filter a proerrty of List<string>. I have made the ItemPropertyDefinition correctly and shows well in the data filter, and I cant select from multiple values, but when I select a value, it does not filter.

Is there any event where I can manipulate the filtering condition? To do something like:

Thank you and kind regards!

Hi,

we have a gridview and with this we have local filtering and sort, but in some columns we have implemented a custom filter.

The thing is when the user clicks on the "Clear Filter" we need to execute some other code, is there any way to differentiate that the user clicked on the "Clear Filter" button?

regards!

I don't know if it's related to my last post: https://www.telerik.com/forums/radopenfolderdialog-generate-a-lot-of-exception

But that dialog is not usable if it's slow like that.  (see video compare to standard windows explorer, https://send.firefox.com/download/9e9308b253d19daf/#Xz4Pj9NHmh7NnG95iTlRRw)

I have a GetForce RTX 2080, I have 4k monitors and I use Windows 1903.  And I use WPF UI 2019.3.1023.45

I want to see the dates in calender with disabled mode of past and future dates.

Good afternoon.
We have a diagram (Tree Layout). Our diagram consists of separate sub-diagrams with no connection between them. Why does the last item automatically go to the second row (in the attach file, it is highlighted in red)? Could you tell me how this can be avoided? We need all the sub-diagrams to be placed in one line.
