Hi,

I have a grid view bound to a RadObservableCollection that contains around a million items. when I select all items and delete them from the grid view (using telerik:RadGridViewCommands.Delete), the whole application freezes and stops responding. I tried all the tricks and tips for optimizing the grid view, but that didn't help.

How do I solve the issue?

Thanks

So as the title states, I'm trying to navigate between rows in a GridView when a cell* ( * : cell correspond to third row and quantity column in my case )  is editing by clicking up/down , so when i navigate up/down , the new selected row also have cell* editing   , here is my gridview

the attached image make clear what i am talking about .

                <trgv:GridViewDataColumn Header="Quantity"
										 MinWidth="75"
										 HeaderTextAlignment="Right"
										 ShowDistinctFilters="False">
                    <trgv:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Quantity}"
									   HorizontalAlignment="Right"/>

                    <trgv:GridViewDataColumn.CellEditTemplate>
                        <DataTemplate>
                            <infctrl:NumberTextBox Value="{Binding Quantity, ValidatesOnDataErrors=True, UpdateSourceTrigger=LostFocus}"
												   HorizontalAlignment="Stretch"

Hello,

I have a RadTreeView that has different item HierarchicalDataTemplates based on the data type.  One of the templates calls for multi-column items.  Whenever I am performing a drag/drop operation the tooltip target appears to be taking the existing template (maybe put into a horizontal stack panel) and showing the info.  (See attachment)  This is not the results I want as it's even showing hidden buttons (X) that should only appear on hover.  

So my question is how can I update the circled part of the tooltip to only show the label (with the styling such as bold removed as well)?

Thank you for your assistance.

I would like to display "Yes" or "No" for a Boolean in RadGridView instead of a checkbox. I would like to implement this changes in xaml. Columns are generating dynamically. This is how it's created now:

 <telerik:RadGridView x:Name="Data" Grid.Row="3" Margin="5" AutoGenerateColumns="False" CanUserSortColumns="True" IsFilteringAllowed="True"
                                 grid:RadGridViewColumnsBinding.ColumnsCollection="{Binding Path=Columns}"
                                 IsReadOnly="False" CanUserResizeColumns="True"/>

I am new in Silverlight coding. Will really appreciate if someone can help.

Hi,

  We are trying to automate RADGridView using CUIT and AutomationElement but we are unable to auto scroll to required row. I have searched in the net and I found this article(http://docs.telerik.com/teststudio/advanced-topics/coded-samples/silverlight/radgridview-automation/scrolling) related to GridView for Sliverlight applications. Is there similar type of the code or any fix for WPF RadGridView? Any help to solve this problem is greatly appreciated.

Hi,

I'm trying to get the current visible range of values in a Candlestick chart, in order to apply different levels of sampling threshold when zoom changes (in an attempt to get adaptative sampling to solve this issue: http://www.telerik.com/forums/adaptive-sampling-zoom-scrolling). Is there any way to get this value, or the limits of the visible area, or at least know when a point is visible or not when zooming in and out?

Thanks.

I declared all my property description in a LocalDataSourceProvider as below. On the first run it works well, but when I uncheck and re-check my custom property are removed (CustomName and AggregateFunction) and property are not put in the right bow (RowGroupDescription instead of ColumnGroupDescriptions) as shown in the attached file. Does it exist some property to set to not lose custom description ?

Hi,

I am being using RadPDFViewer control in one of our Silverlight screen for loading PDF reports. While testing we observed that for large pdf files of size approx. 15mb or above (Total pages 10k+), the find dialog fails to search the specified text search after 3-4 attempts. In our case for the Report of total pages 18000, the search option navigated fine for the first 3 searched locations and then failed to proceed further. I even tried to test the same behavior on your demo site

(http://demos.telerik.com/silverlight/#PdfViewer/FirstLook) with the same report and observed that there too the find dialog failed to perform search after 3 navigations.

Could you please take a look into the issue and suggest further. We have been using the RadControls for Silverlight Q3 2013 version.

Thanks,

Gaurav
