Hi

I am playing with the RadRangeSelector. I have associated it to an existing chart. The chart is dynamically filled using data from the database.

In the image here below, the top control is a RadRangeSelector, the bottom control is a RadChartView.

Notice that my bottom chart shows series as stacked. How can I get the RadRangeSelector also showing stacked series?

Also notice that the dates are not inlined between top and bottom. How can the RadRangeSelector be sorted by dates (as my chart is showing)?

Hi,

I'm using Telerik for Winforms 2023.3.1010 on .NET 7.

While trying to configure the position of my label position using PieTwoLabelColumnsStrategy, only the first label seems to be working with DistanceBetweenLabels property.

 PieTwoLabelColumnsStrategy strategy = new PieTwoLabelColumnsStrategy()
 {
     DistanceBetweenLabels = 50,
     DistanceToLabel = -100
 };

 SmartLabelsController smartLabelsController = new SmartLabelsController
 {
     Strategy = strategy
 };

 radChartView.Controllers.Add(smartLabelsController);
 radChartView.ShowSmartLabels = true;

Here is how I'm filling the chart:

   radChartView.AreaType = ChartAreaType.Pie;
   radChartView.Series.Clear();

   DonutSeries donut = new DonutSeries
   {
       ShowLabels = true,
       LabelMode = PieLabelModes.Horizontal,
       DrawLinesToLabels = true,
       SyncLinesToLabelsColor = true,
       NumberOfColors = categoryCount
   };

   foreach (var v in totals.OrderByDescending(s => s.Statut))
   {
       PieDataPoint point = new PieDataPoint(v.Nombre, v.Statut)
       {
           Label = $"{v.Percentage}% {v.Statut}"
       };

       donut.DataPoints.Add(point);
   }

   radChartView.Series.Add(donut);
   radChartView.Area.View.Palette = KnownPalette.Metro;
   radChartView.SelectionMode = ChartSelectionMode.SingleDataPoint;
   radChartView.BackColor = Color.WhiteSmoke;

With small percentages, it doesn't work (except of the right bottom label)

With higher percentages it seems to be working :

The behavior is quite inconsistent.

Thank you for your help.

Hello,

In my gridview, I have a  progressBarElement in a grid column as explained here:

https://docs.telerik.com/devtools/winforms/controls/gridview/cells/creating-custom-cells?_gl=1*d7lc04*_gcl_au*MTgwMTc5NzcyMS4xNjk5NTI4NjIw*_ga*OTQ3ODE2NTUuMTY5MTU3MzE4Nw..*_ga_9JSNBCSF54*MTY5OTUyODYyMC4xNS4xLjE2OTk1MzMwODcuMzUuMC4w&_ga=2.222397211.1249884809.1699528621-94781655.1691573187

When I export, I don't have the progress bar, only values

 private void RunExportToExcelML(string fileName, ref bool openExportFile)
        {
            ExportToExcelML excelExporter = new ExportToExcelML(this.radGridView1)
            {
                SheetName = "Essai",
                SummariesExportOption = SummariesOption.ExportAll,
                SheetMaxRows = ExcelMaxRows._65536,
                ExportVisualSettings =true,
                
                
                
            };

            try
            {
                excelExporter.RunExport(fileName);

                RadMessageBox.SetThemeName(this.radGridView1.ThemeName);
                DialogResult dr = RadMessageBox.Show("The data in the grid was exported successfully. Do you want to open the file?",
                    "Export to Excel", MessageBoxButtons.YesNo, RadMessageIcon.Question);
                if (dr == DialogResult.Yes)
                {
                    openExportFile = true;
                }
            }
            catch (IOException ex)
            {
                RadMessageBox.SetThemeName(this.radGridView1.ThemeName);
                RadMessageBox.Show(this, ex.Message, "I/O Error", MessageBoxButtons.OK, RadMessageIcon.Error);
            }
        }

I must be missing something obvious here. Given the class below:

    public class ContractForRefinance
    {
        public int ContrID { get; set; }
        public string ContrNumber { get; set; }
        public string LoanClass { get; set; }
        public DateTime LoanDate { get; set; }
        public decimal Balance { get; set; }
    }

I'm trying to set up a multi-column listbox with headers like this:

ListViewDetailColumn contrIDColumn = new ListViewDetailColumn("ContrID");
contrIDColumn.Width = 150;
contrIDColumn.HeaderText = "ContrID";
lstContractForRefinance.Columns.Add(contrIDColumn);

ListViewDetailColumn contrNumberColumn = new ListViewDetailColumn("ContrNumber");
contrNumberColumn.HeaderText = "ContrNumber";
contrNumberColumn.Width = 100;
lstContractForRefinance.Columns.Add(contrNumberColumn);

ListViewDetailColumn loanClassColumn = new ListViewDetailColumn("LoanClass");
loanClassColumn.HeaderText = "Description";
loanClassColumn.Width = 100;
lstContractForRefinance.Columns.Add(loanClassColumn);

ListViewDetailColumn loanDateColumn = new ListViewDetailColumn("LoanDate");
loanDateColumn.HeaderText = "LoanDate";
loanDateColumn.Width = 100;
lstContractForRefinance.Columns.Add(loanDateColumn);

ListViewDetailColumn balanceColumn = new ListViewDetailColumn("Balance");
balanceColumn.HeaderText = "Balance";
balanceColumn.Width = 100;
lstContractForRefinance.Columns.Add(balanceColumn);

lstContractForRefinance.ShowColumnHeaders = true;
lstContractForRefinance.ShowCheckBoxes = true;

foreach (var item in applicationManager.ContractForRefinanceList)
{
    lstContractForRefinance.Items.Add(item);
}

However, the control looks like this:

What am I missing?

Thanks

Probably more of a suggestion than a question.

I would like an FileExportMode that is between the 2 existing modes. It creates or overrides the named Sheet in the given XLSX

User could then:

• Export to a named sheet.
• Add another sheet that references the exorted data
• Run the Export again to refresh the data

I have grid with hierarchy gridviewtemplate.  Is there a way to paginate the child  like the master template?

thanks

I have a list view to apply the waiting bar.

The list view is bound to the bindingList<T> data structure.

I want to apply the waiting bar to prevent UI from stopping while applying the data I have been querying in DB to the list view.

I think if there is a lot of data, it takes a long time because the work takes longer in the CellFomattting part.

Hello Telerik Team,

I want to implement some custom renderings or a overlay for a radChart. I added a screenshot of my application with some annotations. My goal is to remove the dummy resource from the scheduler. The cells of the dummy resource are only used to show workload-percentages. But before I can remove it, I need to display the workload in the ChartView, more precisely in the RangeSelector.

I already implemented a custom CartesianRenderer and custom BarSeriesDrawPart to control the color of the bars depending on the calculated workload. But now I want a Label with the workload percentage centered on each bar. But i don't know how to calculate the the rectange of the area from 0% to 100% to figure out the correct positioning.

My solution so far:

internal class CustomBarSeriesDrawPart : BarSeriesDrawPart
{
    public Font DefaultFont { get; private set; }


    public CustomBarSeriesDrawPart(BarSeries series, IChartRenderer renderer, Font defaultFont) : base(series, renderer)
    {
        DefaultFont = defaultFont;
    }

    public override void DrawSeriesParts()
    {
        //LogHelper.Info("CustomBarSeriesDrawPart.DrawSeriesParts() START");
        if (!(Renderer is CustomCartesianRenderer renderer))
            throw new ApplicationException($"Renderer ist nicht vom Typ \"{nameof(CustomCartesianRenderer)}\"");

        var graphics = ((ChartRenderer)Renderer).Graphics;
        var radGraphics = new RadGdiGraphics(graphics);

        for (int i = 0; i < Element.DataPoints.Count; i++)
        {
            RadRect slot = Element.DataPoints[i].LayoutSlot;

            //how to get the rectangle for the full slot (from 0% to 100% height)? 
            RectangleF barBounds = new RectangleF((float)(OffsetX + slot.X), (float)(OffsetY + slot.Y), (float)slot.Width, (float)slot.Height);

            DataPointElement childElement = (DataPointElement)Element.Children[i];

            float realWidth = barBounds.Width * childElement.HeightAspectRatio;
            barBounds.Width = realWidth;

            barBounds.Height = Math.Max(barBounds.Height, 1f);
            double percentage = 0;
            Color color;

            if (Element.DataPoints[i] is CategoricalDataPoint point)
            {
                percentage = point.Value ?? 0;

                //color = Owner.Auslastungsfarbe(percentage);
                color = renderer.Owner.Auslastungsfarbe(percentage);
            }
            else
                color = Color.LightGray;

            radGraphics.FillRectangle(barBounds, color);

            //radGraphics.DrawEllipse();

            var parameters = new TextParams()
            {
                text = $"{(int)percentage}%",
                alignment = ContentAlignment.MiddleCenter,
                foreColor = Color.Black,
                paintingRectangle = barBounds,
                font = DefaultFont,
            };
            radGraphics.DrawString(parameters, barBounds.Size);
        }
        //base.DrawSeriesParts();
    }
}

Hope you can help my with it.

Hello, 

I'm trying to set up a custom filter for a ListView set in Icon Mode.

Following along with the example provided here: https://docs.telerik.com/devtools/winforms/controls/listview/features/filtering

I've created the following function (no actual filtering functionality has been added yet):

//Apply the filters to the RadListView
bool BrightLife::FilterDatabase(ListViewDataItem^ item)
{

	//Filter by Tree View

	//Filter by Search Bar

	//Filter by Color

	//Filter by Style

	return false;
}

Then, in the constructor of my form, I have the following:

this->LV_Assets->EnableFiltering = true;
this->LV_Assets->ListViewElement->DataView->Filter = FilterDatabase; //<- Problem here

The line which assigns the filter to the RadListView is returning an error in Visual Studio

function "Telerik::WinControls::Data::RadCollectionView<TDataItem>::Filter::set [with TDataItem=Telerik::WinControls::UI::ListViewDataItem ^]" cannot be called with the given argument

I'm not entirely sure what the problem is here and would appreciate any insight to help me get this working. Thanks!
