Hi,

I am using Calculator picker independently without binding its value with any property. I am trying to resets its value after user completes its calculation from the calculator and press save button in the window. I am resetting its value in code behind like "this.CalculatorPicker.Value = 0". On display of the calculator picker it resets the value but on Calculator itself the pervious value remains. I wanted to reset the value on both display and calculator.

Attached is the image after resetting calculator picker value.

I also tried following

this.CalculatorPicker.MemoryValue= 0

this.CalculatorPicker.CacheMode = null

But it didn't work out.

This problem happens when we tried to do some calculations like addition, subtraction, multiplication etc.

Kindly help me in this matter, I will be very thankful to you.

 

Thanks and Regards

On some machines showing a window with a RadPaneGroup that does not contain any Panes throws a ArgumentNullException.

On my dev workstation the window shows fine. The same windows crashes on my dev notebook.
No version differences: I can reproduce the crash by copying the bin directory to the notebook and starting the exe.

As a workaround I created a dummy pane in XAML and remove it in the _Loaded event.
EDIT: This workaround does not help. IsHidden for the dummyPane does not work too.

Hi

 

Just a question. Is possible to set margin directly to image of GridViewImageColumn? Something like:

 

If there isn't any property for do that, Should I modify datatemplate for apply it?

 

Thank you! Regards!

Hi,

The gridview really impress us. The way of showing data is very nice to us. 

But we have a problem about the speed .

When we show the list with many columns(more than 35 columns),every time it takes a lot time(more than 3~4 sec),  even only loading 100 records.

We have tried everything we can try , but the result is not OK yet.

Is the reason that we use the trial version?

If we buy the professional version , can we improve the speed ?

 

We appreciate your help very much.

When select a cell  an then click it  the cell  is in edit mode  

it is too flexible 

is there any way to block it  and  just enter the edit mode by doubleclick

thank you!

Hello,

On the RadSpreadsheet whenever I press the decimal key the default decimal separator apears selected. So whatever I press after that overwrites it unless I unselect it first. This doesn't happen if I press the respective keyboard key (next to the letters). This happens on all the spreadsheet demos and my application. This still happens if I change my default decimal separator.

 The PreviewKeyDownEvent is called when the pressed key is Key.Decimal, but the KeyDownEvent is not called.

My telerik version is 2015.2.728.40 

I am trying very hard to format a cell number, but it is not working as expected.

 

In my country we use the numbers like this: 1.000,00. The 'comma' to represent the decimal and the 'dot' to represent 'thousand' point.

What I want:  The number value to look like this: "0,824".

What I get: the number value looking like this: "823.723.228.995.058,00". (PS: I get this value from a database).

That's really weird.

 

I am setting the format like this: 

 

I have already tried a lot of formats, but none of them seems to work as I expect. I aways get the same result.

 

Is there any other CellValueFormat that I am missing here?

 

Thank you

I've followed the example at:

http://docs.telerik.com/devtools/wpf/controls/radgridview/troubleshooting/styling-custom-header.html

 

Well, it works for most cases, but it doesn't work if the column visibility is bound to a property, and it is invisible when the grid is loaded. It's hard for me to give a simple example that demonstrates exactly the scenario I have, but I've managed to find a different scenario, which reproduces the problem.

 

MyGridView.xaml

 

MainWindow.xaml

 

As you can see, the first tab looks fine, but if you switch to the second one, then the textblocks are all black.

If you try to "debug" it with snoop, and it fixes the binding problem.

 

My scenario is a little different: I have several RadPanes which only one of them is selected. On the other ones, few columns are invisible by using the IsVisible which is bound to a property.

When one of the RadPanes get selected, it loads (and so does the header cells). On the RowLoaded event, I get only the cells that are visible (if I'm correct).

Now if I change that property to true, the column becomes visible, but the textblock is black.

 

I think both problems are the same.

How do I solve it? I need to have both image and text in the header.

 

Thanks.

 

 

 

I have a SeriesProvider with multiple CandlestickSeries. Is it possible to cluster these together using combinemode, as you can with BarSeries? If not how would you suggest that we style the series so that multiple candlesticks can be displayed, side by side, within their relevant categories?

My program needs to display a TimeSpan with days expressed in hours. For example,take the following TimeSpan:

var someTimeSpan = TimeSpan.FromHours(50);

The RadTimeSpanPicker displays the value and allows it to be edited in this format:

2.2:00:00

However, I need it to display the value and allow it to be edited in this format:

50:00:00

I grant that the way this is done out of the box is the way most would want it, and that I am asking for something special.
