Hi,

I'd like to replicate a graph which looks like the one you can see in the attached screenshot with min and max ranges written to the left side of each respective bar. Please note the number of bars and their values are determined at runtime. I know how to create the bar and lineseries programmatically, but not how to create such layout by code.

Hello,

I'm sure this is me, but I'm stuck none the less.

I have two LOB WPF apps that have been running fine for several years. I updated them this week to the newest release version (2016.2.613.40). Now all of the RadDatePicker controls throw a NullRefferenceException in PresentationFramework.dll whenever the calendar pulldown button of the RadDatePicker is clicked.

Stack Trace is below. When I start a new app and use the RadDatePicker of course everything works fine. So I assumed that it must be a dll version mismatch but the Controls.dll and the Controls.Input.dll do match the release version.

Seeing the last stack step involved initializing touch for the control, I've unsuccessfully tried disabling the touch manager as the error still occurs.:

TouchManager.SetIsTouchHitTestVisible(TestRadDatePicker, false);
TouchManager.IsTouchEnabled = false;

Do you have a suggestion on how to troubleshoot this? Thanks in advance!

Scott

Hello,

How to Right-To-Left RadGridView?

HI Telerik,

I am using ScatterLineSeries and I want to show tooltip on the points on Mouse hover. In order to show tooltip I used Point Template while styling the chart. Since I do not want to see the ellipse, I set the color to transparent.  But I have a huge number of points in the series and the UI freezes for long time while rendering the Lines. Then I realized that PointTemplate is causing the freeze. I removed it and the chart is rendering very fast. But the tooltip is not shown anymore. Please help me how to show tooltip without using Point Template.

Thanks,

Shilpa

Is there a way to preserve the expanded groups *using isolated storage* ?....I managed to get the sorting saving, but not the user expanded groups, so that when the app is run again the groups that were expanded previously remain expanded as the user left them (which is a business requirement of our app).

Thanks,

Barry

I have two problems and a question concerning RadRichTextBox:

Problem 1: I have imported (with RtfFormatProvider ) an RTF document (Word RTF ) to RadRichTextBox. This document contains a header with merge fields. Also some other merge fields in the “body” of the document. I have also attached a merge collection with some dummy data to the document. When the document is opened in RadRichTextBox then the merge fields in the head are already mailMerge’ed. The merge fields that are not in the head is not mailMerge’ed . What to do, to avoid that mailmerg are not be performed in the header of the document when open in RadRichTextBox?

Problem 2: Same RTF document (Word RTF) as above. In the head, there is a TAB between the merge fields, but the distance between the merge fields are shorter when the document is imported into RadRichTextBox than when it is open in Word. The rest of the document, look like the same. What should I do to change TAB space in the header?

One question: When it have completed a Mailmerge (test mailmarge). Can I undo (with code) the Mailmerge? I just want to be able to test Mailmerge, that it was correct and then recover the document as it was before the Mailmerge, and also if I have added some text after the Mailmerge or something else like change text till bold. The recovered file should also contain the changes after the mailmarge.

Hi,

       I am implementing an app using RadBook. I am using data templates to bind the data. When the data is more than the page height, i want to avoid the page scroll and port that overflown data in to the next page.

Attaching images to show how i want the data to be spilt in to two pages. Right now, entire data is shown up in a single page with a scrolling.

Is there a method available with Radbook to attain this? If not, what are the alternate solutions i can try to achieve this effect.

Thanks in advance

I want to know, how to faster load RadGridView.

RadGridView code is below.

                        <telerik:RadGridView x:Name="Part_TagListGridView_AI" DataContext="{Binding}" ItemsSource="{Binding TagAICollections}" AutoGenerateColumns="False" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" ShowColumnFooters="True" ShowGroupPanel="False" ShowGroupFooters="False" ScrollMode="RealTime" AllowDrop="True" IsFilteringAllowed="False" GroupRenderMode="Flat" RowStyle="{StaticResource RadGridRowCommonStyle}" MouseDoubleClick="Part_TagListGridView_MouseDoubleClick" RowIndicatorVisibility="Collapsed" CanUserReorderColumns="False">
                            <telerik:RadGridView.Columns>
                                <telerik:GridViewDataColumn  Header="태그ID-AI" DataMemberBinding="{Binding TAG_ID}" IsReadOnly="True" />
                                <telerik:GridViewDataColumn  Header="장치 ID" DataMemberBinding="{Binding DEVICE_ID}" IsReadOnly="True"/>
                                <telerik:GridViewDataColumn  Header="장치 명칭" DataMemberBinding="{Binding DEVICE_NAME}" IsReadOnly="True"/>
                                <telerik:GridViewDataColumn  Header="그룹 ID" DataMemberBinding="{Binding GROUP_ID}" />
                                <telerik:GridViewDataColumn  Header="포인트 인덱스" DataMemberBinding="{Binding POINT_IDX}" />
                                <telerik:GridViewDataColumn  Header="태그 종류(Code)" DataMemberBinding="{Binding TAG_TYPE_CODE, Converter={StaticResource TagTpCodeConvert}}" CellEditTemplate="{StaticResource TagTpComboBox}" IsReadOnly="True"/>

                               ............... column count is 36. .......................

                            </telerik:RadGridView.Columns>
                        </telerik:RadGridView>

And data error check in code behind.

Maximum row count is 1000.

Please, answer to me.

Thank you.

I have a column which shows the state of my object in colors. It also shows a short name as text. The grouping and sorting works on the state, which is an enum.

I would want the text search (as in RadGridView.ShowSearchPanel) to search for the short name.

Is there a setting on the column that lets me do this?

(I really do not want to change the DataMemberBinding which binds to the state, because the looks and function of the cell is in styles and templates, which are reused all over my applications).

Thanks,

Inger Marie

Dear support,

I need a textlabel above the grid that displays the number of filtered columns.

My columnfilters are all implemented the way that is described in der following article http://docs.telerik.com/devtools/wpf/controls/radgridview/filtering/custom-filtering-controls.

Is there a property which contains the number of active filter that I can bind to my textlabel? Or how can I implement it to achieve this aim.

Thanks in advance

Marcus
