Hi,

Is there a way to stop the automatic collapse of the sub item menu when a sub item is selected.  I would like to the have the sub menu still expanded after an item is selected.

Thanks

Hello,

Some of the types I use for the columns of my RadGridView are implementing IComparable so that clicking on these columns sorts them by value.
I also wanted to add column groups to that RadGridView but I noticed there is a severe performance drawback to this: on a sample of 4 rows and ~100 columns, clicking on a column to sort it takes way more time when I have column groups (~0.5s without, 2.5s-4s with).

With a slightly larger sample (6 rows and ~200 columns), it blows up to really unacceptable times (35s-55s)!

For the record, I create columns and column groups dynamically at runtime, the rows are virtualized, and some rows don't have a value for some columns (thus raising System.Windows.Data errors when we load these cells).

Am I doing something wrong?

Thanks in avance!

Hi, 

We have RadListBox control with custom ItemTemplate and ItemsPanelTemplate as VirtualizingWrapPanel. For example, in the case when the count of bound items is equal to 30k and a user wants to "Select all" with Ctrl+A, the program hangs for almost 5 seconds.

I made an investigation and found, that the issue related to a check statement "does this item present in collection"  inside SelectionChanger and it takes more than 92% of the execution time.

I am attaching the call tree after performance profiling:

Do you have any workaround for that or any good advice on how the issue might be solved?

Thank you in advance!

Hi everyone,

I have a problem when adding the items into selectedItems of a multi-selection combobox: it take too long (around 30 seconds) to add a list of 260 items.

Is there any possibility to improve that situation?

Many thanks for your help,

Hi,

We have inserted multiple signed photos into the cell.However, when we exported the image as excel, the shape and position of the image changed, which was inconsistent with that in the RadSpreadSheet.

I've already uploaded an app.

In RadSpreadSheet:

In Excel:

Hi,

i try to always enable the DropDown-Part (the ToggleButton to open the drop down content) of RadRibbonSplitbutton even if the CanExecute of the binded command returns false. How can i achieve this behavior?

i have tried to set IsEnabled of the RadToggleButton via TogglePartStyle of RadRibbonSplitButton but didnt work.

<Style x:Key="SplitButtonToggleStyle" TargetType="telerik:RadToggleButton">
    <Setter Property="IsEnabled" Value="True"/>
</Style>

<Style TargetType="telerik:RadRibbonSplitButton" BasedOn="{StaticResource {x:Type telerik:RadRibbonSplitButton}}">
    <Setter Property="TogglePartStyle" Value="{StaticResource SplitButtonToggleStyle}"/>
</Style>

Thanks for your help!

Best regards,

Hi,

I tried to use a RadMasketTextInput instead of a standard TextBox, mainly because of the SelectionOnFocus/Selectall property.
Always wotks well, but the width of control doesn't use all the space left in the parent as a TextBox, in the same position, does.
I tried with stackpanel, dockpanel and Grid, this is the attempt with dockpanel:

<DockPanel Grid.Row="0" Grid.Column="0" Margin="12,0,0,0" HorizontalAlignment="Stretch">
				<Label VerticalAlignment="Center" 
Content="{DynamicResource  ResourceKey={x:Static r:ResourcesKeys.NameLabel}}" />
	<t:RadMaskedTextInput 
	  HorizontalAlignment="Stretch"
	 SelectionOnFocus="SelectAll"
         Value="{Binding SorgenteName}"/>			
</DockPanel>

And with textbox:

<DockPanel Grid.Row="0" Grid.Column="0" Margin="12,0,0,0" HorizontalAlignment="Stretch">
				<Label VerticalAlignment="Center" 
				    Content="{DynamicResource  ResourceKey={x:Static r:ResourcesKeys.NameLabel}}" />
				<TextBox 
									  HorizontalAlignment="Stretch"
							Text="{Binding SorgenteName}"/>
			</DockPanel>

With textbox I have the desired layout.

Thank you in advance
