Hi,

I was wondering if there is a way to use tooltips on a line series instead of a trackball. For example if i clicked on a certain line series in a multiline series chart, the information for that point of the line series would be displayed to the user?

Thank you.

RadDateTimePicker - Setting Selected Value To Today?

I've got a few RadDateTimePickers which are all bound to various data sources. Some of them have a null value, some have values, which all display fine - however the issue I am having is that when you click the field to select a date, the default date that is selected is from when I added the control to the form.

This should be today's date, however the value of the field should remain null until the user has clicked a date. They do need to be able to select a date in the past/future though as well.

I'm using the latest version of Telerik UI for WinForms on a VB.net project.

Any help would be much appreciated.

Thanks, Shane

[Solved] Programmatically sort multiple columns

Hi, basically I want to simulate the Shift + click to sort multiple columns. For example, if the user click on Column A to do an ascending sort, I want to also sort Column B ascending.
I added the sort descriptors in the designer and it works on startup, but as soon I click on Column A or B, the original sort descriptors are lost.
Any suggestions?

Thanks,
Andy

Polar chartView SelectedPointChanged

How to make it to catch ChartViewSelectedChanged event? Seems to work for other chart types such as cartesian or pie..

public Form1()

{

InitializeComponent();

radChartView1.Controllers.Add(new ChartSelectionController());

radChartView1.SelectionMode = ChartSelectionMode.MultipleDataPoints;

radChartView1.SelectedPointChanged += new ChartViewSelectedChangedEventHandler(OnChartSelectedPointChanged);

}

private void OnChartSelectedPointChanged(object sender, ChartViewSelectedPointChangedEventArgs e)

{

PolarDataPoint pt = e.NewSelectedPoint as PolarDataPoint;

if (pt == null) return;

System.Diagnostics.Debug.WriteLine(" angle = " + pt.Angle + " value = " + pt.Value);

}

[Solved] Printing a PDF-File without print preview

Hello,

my goal is to print a PDF-File directly to a printer without showing the print preview.

This is what I tried:

rpd = new RadPrintDocument();

rpd.PrinterSettings.PrinterName = "printer";

rViewer = new RadPdfViewer();
rViewer.LoadDocument(sFileName);
rViewer.DocumentLoaded += rViewer_DocumentLoaded;

static void rViewer_DocumentLoaded(object sender, EventArgs e)

{
//rViewer.PrintPreview(rpd);
rViewer.Print(false, rpd);

}

When I send it directly to the printer ( rViewer.Print(false, rpd); ) it always prints it in portrait-format.

When I use rViewer.PrintPreview(rpd); and then press the Print-Button, it works.

Does anybody have an idea? Thank you!

Anchor not work during changing text size to 125%

I am using Win7 system and latest build of Telerik package (2011.3 11.1116 - Nov 16, 2011).

I've made two similiar forms - using ordinary WinForm components (see f-100.png attached) and Telerik form (see t-100.png). No one Telerik theme was used.

When I change text size to 125% - these forms look like that:

a) Ordinary WinForm's form looks fine as expected - see f-125.png.

b) But Telerik form has different behavior (see t-125.png):

GroupBox with anchored position comes out of border (groupbox with dock position has appropriate size).
Treeview with anchored position do not resized at all (treeview with dock position has appropriate size).
Buttons and textbox do not resized (to reflect change of text size) and their anchor position do not work.

I presume that other controls also have problems with anchoring position and resizing.

Note that Telerik form painted fine if we use 150% for changing text size (see t-150.png). Only 125% has that bug (actually, there are some interval from 120% to 135%, something like that).

Should I change something in code to prevent this (I mean, using dock position is not applicable all the time)?

[Solved] Column chooser tooltips

Hello Telerik Community,

Does anybody know a way to add a tooltip to the column chooser? I know it is not a matter of life or death, but, in one of my projects i condensed a little bit some column header names, and now, when they are on the column chooser nobody, including me, is able to deduce which is the column content :( .

Would be possible to get some reference to the column chooser and add a tooltip to each column?

Best Regards

Andrea

Unpinned column not shown

Hello,

I'm facing a pretty strange behavior when unpinning a column in a RadVirtualGrid:

1. Pin (left or right) 1st column
2. Scroll horizontally (to not display 2nd column)
3. Unpin 1st column
4. Scroll horizontally to display 1st column
=> 1st column is hidden, the only way to make it visible is to resize a column or the entire window

It seems to be a bug and I'm trying some workaround:
- Is there a way to force refresh the grid ? (RadVirtualGrid.TableElement.SynchronizeRows is not working in this case)
- Is there an event that can be captured on column pinned state change, in order to force a refresh at this time ?

Regards.
