Hello,

While exporting data from Pivot Grid into Excel, always we are getting OOM (Out Of Memory) exception. Even the Pivot Grid contains of 20000 records.

And if we export 4000-5000 records, the excel export is very very slow.

If we increase the number of records then we are getting OOM exception.

The data binding and other things are working fine as we expected with this Pivot Grid. Only thing we are facing the issue is Pivot Grid Excel export.


Actually we have implemented the code based on the below link provided by Telerik. In the Telerik SDK browser also the Pivot Grid is not exporting well. There also we are getting OOM exception if the Pivot Grid contains more than 20000 records.

Please help me resolve the Pivot Grid - Excel export OOM and performance issues.


Thanks,

Hi,
I try to preform UI Automated tests using Microsoft UI Automation Tests Library.
I would like to find shapes that I placed on the Map using this library.
The deepest I can get is RadMap Control.
Is it possible to go deeper and find shapes in the map?

I have a every simple RadTreeview with 2 level deep children and a wrap panel to mimic explorer list view style.
The root level is showing fine, but beyond root level is NOT showing the children nodes.  It is, however, only showing the place holder (radtreeview.png).

It works fine if I use System.Windows.Controls.TreeView(TreeView.png), but I need to use RadTreeview.

Any help would be much appreciated.

           <telerik:RadTreeView x:Name="trvMenu" 
                             ScrollViewer.VerticalScrollBarVisibility="Disabled">

            <telerik:RadTreeView.ItemsPanel>
                <ItemsPanelTemplate >
                    <telerik:RadWrapPanel Orientation="Vertical" />
                </ItemsPanelTemplate>
            </telerik:RadTreeView.ItemsPanel>
           
            <telerik:RadTreeView.ItemTemplate>
                <HierarchicalDataTemplate DataType="{x:Type MenuItem}" ItemsSource="{Binding Items}" >
                    <TextBlock Text="{Binding Title}" />

I'm using the Telerik DragAndDrop in some of our applications and in general this works awesome. But at this point I'm testing my application with some touch devices. In the application is a Scrollviewer wich has PanningMode turned on, he DragAndDrop-controls are in this scrollviewer. 
At first it was like dragging these controls wasn't working. But later I noticed there was a visual shown on drop but it is just blocked when dragging the control around. I adjusted my scrollviewer to only scroll when there are two fingers used. But this didn't change the fact that the visual of the dragging is still blocked.

Also I have tried some tricks with the OnPreviewTouchDown- and OnPreviewTouchUp events of the scrollviewer. Till now I haven't found a good solution.

Is there anyone around here that tried the same or that has an option to try?

Thanks,

I am using the following code to get an array of values from Excel;

I then try to bind the array to a GridView using;

However I get the error; "Array was not a one-dimensional array".

I have tried converting the array to an observable collection;

but this displays the error; ​"The best overloaded method match for 'System.Collections.ObjectModel.ObservableCollection<object>.ObservableCollection(System.Collections.Generic.IEnumerable<object>)' has some invalid arguments".

How can I bind the Excel data returned to the grid?

I am using dateTimePicker I want to disabled the dates later than from today's date and I want to show a kind of label showing today's date all the time inside the datetimepicker control  so that when user is navigating to other dates/months/years,today's date would be visible all the time.

Is direct insertion possible??

Background: My previous experience with reading online documentation are iOS docs Android docs Sqlite docs CPAN jquery angular etc etc. So that is my point of reference here.

Often when i try and search the telerik documentation i come across pages that looks like this.
http://www.telerik.com/help/silverlight/f_telerik_windows_controls_diagrams_raddiagramshapebase_glidingstyleproperty.html

So this is a property , i already knew that. But what does it do ? how am i supposed to find out what this property is used for ?
to me this type of documentation does not tell me anything i could not find out via clicking in the Object browser.

Am i using the documentation the wrong way or is it just documentation for documentations sake ?

Hi all,
1. Please go to: http://demos.telerik.com/silverlight/#RichTextBox/MailMerge
2. In the UI you will see Insert Merge Field
3. Click it and select RecipientPhoto

This add {MERGEFIELD RecipientPhoto}
How to add {INCLUDEPICTURE {MERGEFIELD RecipientPhoto}} ?

Insert Field programmatically ( http://www.telerik.com/help/wpf/radrichtextbox-features-mail-merge.html ) is not answer on the question and it insert the field in the first line of the document. So I need user to select position of the picture as he can do it with normal text field.
