The exception is thrown and the document cannot be imported.

Currently, showing a dialog can take 10-20 seconds when started in DEBUG mode. 

And 3-5 seconds RELEASE mode. Improve the loading time.

A little way to speed up is to set ExpandToCurrentDirectory to False.

Add the ability to specify the start and end for the grouping. This functionality is available in MS Excel.

When for example we added a new business object which has a lower value, the lower value indicator is not updated and two indicators are shown.

The indicators and the markers are not updated when the data is changed at runtime.

Workaround:
Manually invalidate the arrange of the panel that holds the sparkline's markers. You can do that by finding the ScatterPanel control in the visual tree of the sparkline and then calling its InvalidateArrange() method. Call the InvalidateArrange() method at the moment when the data of the sparkline is updated. 

var panel = this.sparkline.FindChildByType<ScatterPanel>();
if (panel != null)
{
    panel.InvalidateArrange();
}

Instances of RadFixedDocument and PdfFormatProvider are kept in memory by a WPF internal collection (_sizeChangedChain).

Selecting a large number of items through the UI or programatically with the Select method when in Extended SelectionMode leads to a degraded performance. As a workaround the Multiple SelectionMode can be used instead.

Hi Team, 

Dennis Callahan from Telerik submitting this on behalf of Don - 

If your team could create a theme for UI for WPF that mimicked the look of a UWP application and responded to the Windows 10 Light and Dark setting that would be excellent. I have not found such a theme in any of the products I have looked at so if Telerik could do it I think it might be the first.

The selection inside the cells of the GridViewMultiColumnComboBoxColumn is not refreshed when its ItemsSource is updated during runtime. 

Adding Greater/LessThan filter operator results in an exception when using a DataProvider and a DataTable as its source

Clearing and updating the ColumnGroups collection results in degraded performance when there is a big amount of column groups.

Copying a Table and then pasting it as plain text results in each table cell added on a new line. Instead, the content of the cells on a single table row should be separated by tabs and newlines should differentiate the table rows.

When opening the system menu with a RadRibbonWindow in a setup with 2 monitors with different DPI, the menu is misplaced. 

Add a property to force only allowing uppercase values, without needing to specify a number of characters or have the underline in the control.

 

This is achievable in code, but it seems unnecessary to go to such lengths for each instance where it is needed.

 

private void bankCode_ValueChanging(object sender, Telerik.Windows.Controls.MaskedInput.RadMaskedInputValueChangingEventArgs e)
        {
            if (e.NewValue == null)
                return;

            string newValue = e.NewValue.ToString();
            if (newValue.Length > 0)
            {
                newValue = newValue.ToUpper();
            }
            this.txtBankCode.ValueChanging -= this.bankCode_ValueChanging;
            this.txtBankCode.Value = newValue;
            this.txtBankCode.ValueChanging += this.bankCode_ValueChanging;
        }

We can expose a way to select the text of the selected item when the MCCB is focused.

For example if Resource "Stol 2" does not have any Appointments it should not appear in the view

Good morning,

can You implement in one of the next releases the regex and case sensitive search? I provided you the Visual Studio 2019 search screenshot

The received exception is: "System.ArgumentNullException: 'Value cannot be null.
Parameter name: source'".

changing file system via rad file / save dialogs in opened in new app domain causes an application crash
"The calling thread cannot access this object because a different thread owns it."

When invalid rows that were loaded but not in viewport get valid, the invalid state (row validation indicator) is still visible.
