Use attached to reproduce. 

One should not be able to use the ribbon bar buttons when a protected document is opened or the rich text editor is read-only. 

If i have lots of group, the horizontal axis gets full with the square 4x4 groups, but the vertacal axis has lots of empty space.
I could break the squareness of the groups to make them longer in the vertical axis, but that seems a bit ugly.

However, I cannot seem to find a way to put a group under another group, therefore utilising both the X and Y dimensions well.

Can it be done?



i.e.

--Group 1--   --Group2--

Tile     Tile     Tile     Tile

Tile     Tile     Tile     Tile



--Group 3--

Tile      Tile

Tile      Tile

 

Before (How it is now):

  After (How I'm proposing it can be):

To reproduce:
- Filter a self-referencing grouped grid. 

Workaround:
private void _rgvFreeCodeValues_FilterChanged(object sender, GridViewCollectionChangedEventArgs e)
{
    foreach (var row in RgvFreeCodeValues.Rows)
        row.IsExpanded = false;
}

private void _rgvFreeCodeValues_FilterChanging(object sender, GridViewCollectionChangingEventArgs e)
{
    foreach (var row in RgvFreeCodeValues.Rows)
        row.IsExpanded = true;
}

To reproduce: please refer to the attached sample project and follow the steps from the attached gif file.

1. Run the project and type "hana" in the second filter cell. You will notice that after a few seconds the input is handled and the grid is filtered.

Workaround: use RadVirtualGrid instead. 
https://docs.telerik.com/devtools/winforms/virtualgrid/overview
https://docs.telerik.com/devtools/winforms/virtualgrid/filtering/filtering

Second workaround: https://docs.telerik.com/devtools/winforms/gridview/filtering/how-to/filter-on-enter

This was working this way in 2017 then we changer it so all rows are affected. 

Bot modes should be supported. 

Caret jumps several symbols to the right when arabic or persian is used and user deletes the dot symbol. As a result the wrong symbol is deleted.

When a PDF document contains images compressed with CCITTFaxDecode with applied BlackIs1 parameter, black color is visualized as white and white as black.

Other themes are also missing the IsSelected state, the fix should also handle them.

I need to tab though the form fields in RadPdfViewer instead of having to click in each one

To reproduce:

Open a large document and start scrolling fast. 

The pages a blank when scrolling and are rendered after scrolling stops.

To reproduce: 

-Open the FileExplorer example. 

- Resize the panel (see attached).

This will handle the scenario of having different image sets for different DPI.

Changing the DataSource or scrolling are slow.

Create a grid with more than 20 columns and add 5K rows for example. Maximize the form and try to scroll with mouse wheel. You will notice that the scrolling performance is worse compared to the normal state of the form with less visible visual elements.

Workaround: this.radGridView1.EnableFastScrolling = true; and use the scrollbar's thumb

Second workaround: use paging:  https://docs.telerik.com/devtools/winforms/gridview/paging/overview Thus, you will display as many rows as possible to display on the screen per page. Instead of scrolling, you will navigate through pages.

Hello,

We have developed an ASP.NET application and a WinForms application that both uses Telerik RadScheduler. The applications share the same data.

We have set EnableExactTimeRendering = true to prevent appointments to falsely be displayed as collisions.

Our problem is that appointments with short durations (0-4 minutes) are totally invisible in the WinForms Scheduler. In the ASP.NET scheduler all appointments are visible. An appointment with no duration (0 minutes) is shown as 30min appointment in ASP.NET while 1-minute appointments are shown as a thin line which is ok as we use tooltips for all appointments.

How can we make all appointments visible in WinForms and still use EnableExactTimeRendering? Of course, the rendering will not be exact for small durations but that is better than not showing the appointments at all. We would like to set a minimum size for appointments.

Best regards,
Daniel Gidlöf

Isnt the hilighted line (contains branch) very unoptimized.

https://rhale78.wordpress.com/2011/05/16/string-equality-and-performance-in-c/

Multiple ToLower string operation. Why not let the framework do the operation since you are always using ordinal?

optimized version: return item.Text.Contains(this.Filter, StringComparison.OrdinalIgnoreCase);

 

protected virtual bool DefaultFilter(RadListDataItem item)
    {
      switch (this.suggestMode)
      {
        case SuggestMode.StartWiths:
          return item.Text.StartsWith(this.Filter, this.StringComparison);
        case SuggestMode.Contains:
          if ((this.StringComparison & StringComparison.InvariantCultureIgnoreCase) == StringComparison.InvariantCultureIgnoreCase || (this.StringComparison & StringComparison.InvariantCultureIgnoreCase) == StringComparison.CurrentCultureIgnoreCase)
            return item.Text.ToLower().Contains(this.Filter.ToLower());
          return item.Text.Contains(this.Filter);
        default:
          return item.Text.StartsWith(this.Filter, this.StringComparison);
      }
    }

Workaround: use custom filtering instead of CompositeFilterDescriptor:

FilterDescriptor filter = new FilterDescriptor();
filter.PropertyName = this.radMultiColumnComboBox1.DisplayMember;
filter.Operator = FilterOperator.Contains;
this.radMultiColumnComboBox1.EditorControl.MasterTemplate.FilterDescriptors.Add(filter);
this.radMultiColumnComboBox1.EditorControl.EnableCustomFiltering = true;
this.radMultiColumnComboBox1.EditorControl.CustomFiltering += EditorControl_CustomFiltering;

 private void EditorControl_CustomFiltering(object sender, GridViewCustomFilteringEventArgs e)
 {
     string searchText = this.radMultiColumnComboBox1.MultiColumnComboBoxElement.EditorElement.Text;
     if (searchText != string.Empty)
     {
         Instrument instrument = e.Row.DataBoundItem as Instrument;

         e.Handled = true;
         e.Visible = instrument.Isin.Contains(searchText) || instrument.Description.Contains(searchText) || instrument.AlphaCode.Contains(searchText) ||
                     instrument.MicMarketplaceCode.Contains(searchText) || instrument.WorpMarketPlaceDescription.Contains(searchText) ||
                     instrument.InstrumentType.Contains(searchText) || instrument.DerivateIsin.Contains(searchText);
     }
 }

To reproduce:

-double click an option in the MultiColumnCombobox editor and close the editor in the selected index changed event.

To reproduce:

Add a RadBindingNavigator to a form and change its name.

Bind it to something.

Workaround:

Leave the default name.
