Hi,

I downloaded the Q2 version of WPF Controls and installed the same. When trying to view the samples for window the application crashes. I am attaching the  stacktrace. Do let me know how can this be viewed without throwing any error.

I create empty project, add line
<telerik:DateTimePicker />

and when user try to change antyhing exception is thrown: Nullable object must have a value.

Hi

I would very much appreciate some help on the following problem:

I have a project in which I have a RadChart. Upon starting my application the RadChart is populated with 3 data series (Car, Property and Travel) in a stacked bar format. User can then click on any of the 12 resulting ChartItems, in which case the chart is repopulated by a new DataSeries, this time in a line format. (Basically it is based on Telerik's Drill Down demo - the first chart displays sales per month, the second chart breaks it further into days.)

To return from the second view back to the first view, user clicks the Reload button, which runs the same method (ConfigureMonthlyRevenue()) that was run upon starting the application.

There were no problems with this code until I upgraded to Q2 yesterday. Now all runs smoothly until I hit the Reload button and the application hangs. When I pause it, I get the "Cannot evaluate expression because the code of the current method is optimized" error when hovering over the bit of code where I'm adding the series to the chart. Please see the code snippet below:

//This is the bit that's run upon starting the app (without problems) and then when the Reload button is hit (which is when it hangs on the bold line)

private void ConfigureMonthlyRevenue()

{

 

this.past12Months.DefaultView.ChartArea.DataSeries.Clear();

this.past12Months.DefaultView.ChartTitle.Content = "Past 12 Months Revenue";

DataSeries seriesCar = new DataSeries();

seriesCar.Definition = new StackedBarSeriesDefinition();
seriesCar.LegendLabel = "Car";

seriesCar.Definition.ShowItemToolTips = true;

DataSeries seriesProperty = new DataSeries();

seriesProperty.Definition = new StackedBarSeriesDefinition();
seriesProperty.LegendLabel = "Property";

seriesProperty.Definition.ShowItemToolTips = true;

DataSeries seriesTravel = new DataSeries();

seriesTravel.Definition = new StackedBarSeriesDefinition();
seriesTravel.LegendLabel = "Travel";

seriesTravel.Definition.ShowItemToolTips = true;

this.FillWithRevenueData(seriesCar, seriesProperty, seriesTravel);

chartArea.DataSeries.Add(seriesCar);

chartArea.DataSeries.Add(seriesProperty);

chartArea.DataSeries.Add(seriesTravel);

chartArea.AxisX.StripLinesVisibility = Visibility.Collapsed;

chartArea.AxisY.Title = "(thousand dollars)";

chartArea.AxisX.TickPoints.Clear();
chartArea.AxisY.Step = 100d;

chartArea.AxisY.DefaultFormat = "C0";

string[] months = new string[] { "Jul", "Aug", "Sep", "Oct", "Nov", "Dec", "Jan", "Feb", "Mar", "Apr", "May", "Jun" };

for (int i = 0; i < months.Length; i++)

{

 chartArea.AxisX.TickPoints.Add(new TickPoint());

chartArea.AxisX.TickPoints[i].Label = months[i];

}

}

//When chartItem clicked

private void chartArea_ChartItemClick(object sender, ChartItemClickEventArgs e)

{

this.past12Months.DefaultView.ChartArea.ChartItemClick -= this.chartArea_ChartItemClick;

string axisItemLabel = past12Months.DefaultView.ChartArea.AxisX.TickPoints[e.ItemIndex].Label;

string product = e.DataSeries.LegendLabel.ToString();

past12Months.DefaultView.ChartTitle.Content = string.Format("Daily Revenue {0} ({1})", product, axisItemLabel);

 

DataSeries series = new DataSeries();

series.Definition = new LineSeriesDefinition();

series.LegendLabel = "Daily Revenue";

FillWithDailyDummyData(series);

past12Months.DefaultView.ChartArea.DataSeries.Clear();

past12Months.DefaultView.ChartArea.DataSeries.Add(series);

string[] days = new string[] { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30" };

for (int i = 0; i < days.Length; i++)

{

past12Months.DefaultView.ChartArea.AxisX.TickPoints[i].Label = days[i];

}

this.past12Months.DefaultView.ChartArea.ChartItemClick += this.chartArea_ChartItemClick;

}

Any help with this would be much appreciated.

Thank you

I'm trying to get the RadGridView for WPF to work in our software, and I was wondering if it is possible to show the Item count of a group in the group header without using predefined GroupDescriptions and preferably a XAML-only solution.

So far, all the examples on AggregateFunctions I have found, either have predefined GroupDescriptions in XAML or set the AggregateFunction programmatically using a hardcoded GroupDescription.

Edit:

I managed to fake the desired functionality by using the GroupDescriptions.CollectionChanged event:

 

private void GroupDescriptions_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e)

{

if (recordings.GroupDescriptions.Count > 0)

{

foreach (RadGroupDescription rgd in recordings.GroupDescriptions)

{

CountFunction cf = new CountFunction(rgd.PropertyName, rgd.PropertyName, "");

rgd.AggregateFunctions.Add(cf);

}

}

}

Strangely, the e.Action is never Add when dragging a column to the GroupPanel, so I had to do it this way.

 

 

Upgraded to 2009.2.701.35 and now it does not use the value in the HeaderText field.

This displays "Data.FirstName" as the column header instead of "First Name"


This displays "Default" as the column header instead of "Default Value"

Hi, i have a problem with a GridView, Is possible add events to gridView's childs? or how do I access to Childs?, I need the event Mouse_DoubleClick for the child

Hi,

I have a Button named photo and label named Signature on the form. and one submit button. When user clicks photo button or click on the label, some operation take place. When user clicks submit, operations related to Photo button and signatures label submits to the database. But if the user doesn't click photo Button or label, no DB is updated.

I want to know is there any way , I can force user to click the button or label . These are WPF controls.

Thanks,

Veena

I'm trying to change the date format of the RadDatePicker to display only "dd/MM".  I followed the example here but it doesn't seem to work - I've put the code in the Loaded event if that's any help.

Also, if there's any way to declare this in XAML it'd be a much neater solution.

Hi.

I do not know WPF (yet) and I haven't tried the controls, but from the demos it seems that the customization options for the controls is largely about color, linestyle and gradients.

I am looking for a WPF set which gives options to customize all visuals. Some customers may want click-handling on the chart legends, some want visuals like engineering units on top of the graph, some like it under, some would like it as tooltip. Some would like the various curves to be possible to enable/disable. Some would like to highlight a set of curves. Some would like other metadata to be drawn onto the graph backdrop. Some present a jpg from mspaint and state that they want it "exactly like that".

How customizeable are the WPF radcontrols from Telerik? Are their visuals fully expressed in XAML that I can edit so that I for example easily can remove/add a stackpanel with dimmed curve legends within the graph? 

That kind of stuff.

The screen real estate is very important, so it is important that, if I choose to not use the axis, title, legends, border etc, that they collapses and do not take up space. ie, That it can be stripped down to operate pretty much "fullscreen" within another wpf control container.
