If I zoom in to the chart I end up with multiple X-Axis ticks with duplicate values.
I have stepped through the LinearAxisModel code using Reflector and found that in the GenerateTicks method it has a ZoomWidth of ~50.0 and a MajorStep of 20.0.
Which over a range of min = 0, Max = 140 ends up with it generating far too many ticks for the data range.
Is there a way to control the number of ticks that are generated so that only one tick per distinct data value are displayed?
Thanks

Hi Telerik,
I am using ScaterLIneSeriers because our axes (x&Y) are linear axies. We add multiple ScatterLineSeries dynamically using code. We see following list of issues.
1. There is no option to sort the axis data automatically.
2. We thought if we sort them and add it it will work fine. But it does not cover all the cases because our series are sparsed. When there is sparsed data and some data does not overlap and the sequence are not done automatically the graph looks very ugly.
3. So, We tried the workaround of creating dummy series with all the points and add that as first series and set their visibility to false and it did not help that much because the rendering of series is not same as the ordering of adding the series.
4. The ScaterLine series does no render same as excel when the data is not sorted and the data has both positive and negative values.
We need to know how to solve this issues. Is there any patches available.
Thanks
Mohan.

Hi,
I am facing issue while working with Localization, my scenario is as follows:
=> I am having Rad DataGrid and we are binding the columns dynamically, while binding I am handling the localization in code behind from the resx file.
The scenario in which I am facing issue is for certain columns I need to change color of some rows depending on certain condition. To achieve this I hardcode the column name and it was working fine by using a converter. But as I can't hardcode the column name I need to use localization and get the results which I am not able to achieve. here is the sample code how we I approached it when I hardcoded
If u observe I hardcode the "abc" value while binding.I want to pull this hardcode colum name from from resx file and get the value of the column.

Hello,
Started from how-to-bind-custom-observablecollection-to-radribbonsplitbutton, now I want to add a sub menu item.
I could still use a RadMenuItem-based object for the sub menu item? I will also know what the parent menu item should be.
However, I don't know which elements, properties, etc, to add the sub menu item to?
Thank you...

Michael Powell

Hello,
I've got a custom ObservableCollection I want to bind to using RadRibbonSplitButton.
Is there a simple example how to bind a collection to a RadRibbonSplitButton (or RadSplitButton?) DropDown data context?
Thanks!

Is there a control like a split button (button+menu) for use with the
RadRibbonView? I am using the RadRibbonButtons of course, but one of
them I would like to use as a split button and drop down a menu. Thank

I have a RadGridView bound to ObservableCollection. This collection is constantly updated and on first binding the grid represent the data correctly. But then I click on one of the headers to sort the data in the grid. After that behaviors on adding a new row become as following:
- the grid adds the row to the end of the list only, it doesn't sort data dynamically according sorting column;
- sometimes (often) the grid creates duplicate rows while underlying collection contains correct data;
I couldn't find in documentation any info that I should programmatically sort underlying collection each time after adding row or rebind it every time so the grid shows it correctly. What should I do to fix it or it\s a norm for Telerik Grid?

Hi.
We have an implementation of Drag&Drop of items from outlook to a treeview using the telerik DragDropManager.
xaml code:
code-behind:
We then have a function : OnPreparedItemDrop(object sender, DragEventArgs args)
...Where I want to launch a new dialog and add some metadata to the files dragged in.
When using a dialog.ShowDialog() the calling thread here freezes. This causes the source application(outlook) to be completely unresponsible until my dialog has been closed and the function returns. It also leaves the mouse cursor in "drag-drop" mode when hovering stuff outside my application.
I am fond of this style of opening and handlign dialog outputs:
The alternative I see at the moment is to add logic to the view cancel/close events to do cleanup, or mess with the dispatcher and threading. What is the proper approach here?

Hello,
I'm implementing a RadCartesianChart with dynamic ChartDataSource and data sampling.
Everything's fine but I'd like to sample via a sum function and not via the default average one.
So I created a new SumBarSeries which inherits from BarSeries as shown below :
public class SumBarSeries : BarSeries
{
protected override ChartAggregateFunction GetValueAggregateFunction()
{
return new ChartSumFunction();
}
}
There's a min, max, average, keepextremes, first and last function but no sum function.
Is there a simple way to add such a function?
Furthermore is it possible to change dynamically the sampling function just like the old RadCharts without changing the BarSeries class (ie. SumBarSeries)?
Thanks,
Michel LACOMBE
