Scroll position indicator when using VirtualQueryableCollectionView

I have a requirement to handle a large number of records in a grid. So my radgrid is set to deferred scrolling and is lazy loading the records using VirtualQueryableCollectionView. That works really well.

My problem is in the scroll position indicator. I can't bind it to a property in the record because they are not loaded yet. Setting scroll mode to real time is not an option. What would be best solution here?

Occurrence appears when an exception exists for it.

Hello.

Sorry I didn't follow your indication to open a new ticket.

There it is.

Here is my problem:

1) I create a recurrent appointment (i.e.: every week day at some time).

2) I make an exception (i.e.: I move one occurrence on the week to one our later)

3) I persist the data

4) When I reload from DB, both the occurrence and the exception are shown.

I attached one pic (recurrence.png) showing this.

I managed to create a project where I show how I save and recover the appointment and the exception. The example shows exactly how I do it, except for the persistence layer) (see SchedulerTest.png, which is a zip file in fact)

To make clear my point, I took a screen shot of the sample project showing what I want to fix (scheduletest.png).

There is something I am missing, but can't figure out what.

Thanks.

RadHorizontalLinearGauge hide labels and move the lines to the bottom

Hi there,

I'm trying to hide the labels of the bar and I want to move the lines to the bottom.

I found out that I can hide labels by setting the LabelUseRangeColor to true. I don't think this is the correct way. Can anyone help me with this?

I also want to move the lines from the top top the bottom of the RadHorizontalLinearGauge.

Fixed Height for Slots

Hello,

I would like to have fixed heights for the slots even when I change the Minor/MajorTickLength.

Currently I get this (5minutes.jpg, 15minutes.jpg and 30minutes.jpg)

and the result I would like to have is: 5minutesRight.jpg, 15minutes.jpg, 30minutesRight.jpg

I tried setting the VerticalWeekMinor/MajorItemTemplate or the MinAppointmentHeight to fixed height but that didn't yield the result I was looking for.

Any help would be appreciated.

Best regards!

Floating image on header/footer?

Our enterprise has chosen Telerik as our tool to convert XLSX files to PDF. One limitation that has become an issue for our clients is that Telerik's API doesn't seem to support images in the XLSX header/footer. I've been trying to get around this limitation using the Telerik.Windows.Documents.Spreadsheet.Model.Shapes.FloatingImage class, but when I move the image past the top margin into the header region, the image gets cut off. Is it possible to work around this somehow? I was hoping to see a z-index parameter in the FloatingImage class, but nothing like that seems to exist.

Column text alignment issue.

I have two columns in the GridView. I want one column's text(including header) is on the left, the other column is on the right.

<telerik:GridViewDataColumn Header="Content" DataMemberBinding="{Binding Content}" TextAlignment="Left" HeaderTextAlignmemt="Left" />

<telerik:GridViewDataColumn Header="Date" DataMemberBinding="{Binding Date}" TextAlignment="Right" HeaderTextAlignmemt="Right" />

But it is not working, two columns are always aligned to the left. Then I used Visual Tree to check the properties. For the GridViewCell.

PART_CellBorder [Border]

Background_Over [Border]

Background_Selected[Border] etc

The default HorizontalAlignment is Stretch. I am not sure how to set the styles for the alignment.

Thanks.

[Solved] How to select a folder instead of individual files

I'm looking for a way of not just selecting files for upload but entire folder structures. I was hoping I could use the CreateOpenFileDialog delegate to return the RadOpenFolderDialog however this function expects a return type of Microsoft.Win32.OpenFileDialog which the Telerik controls do not inherit from.

Any suggestions?
