This code produces a blank image. Am I missing something?

var radChartView1 = new RadChartView();
radChartView1.AreaType = ChartAreaType.Pie;
PieSeries series = new PieSeries();
series.DataPoints.Add(new PieDataPoint(50, "Germany"));
series.DataPoints.Add(new PieDataPoint(70, "United States"));
series.DataPoints.Add(new PieDataPoint(40, "France"));
series.DataPoints.Add(new PieDataPoint(25, "United Kingdom") { Label = "My Label" });
series.ShowLabels = true;
series.DrawLinesToLabels = true;
series.SyncLinesToLabelsColor = true;
radChartView1.ShowSmartLabels = true;
radChartView1.Series.Add(series);
flowLayoutPanel1.Controls.Add(radChartView1);
radChartView1.ChartElement.UpdateLayout();
var name5 = Path.Combine(_outputBasePath, "data05.png");
ThemeResolutionService.AllowAnimations = false;
radChartView1.ExportToImage(name5, radChartView1.Size, ImageFormat.Png);

I am calling a panel from another form so I can re-use it without having duplicate code. This panel has a RadViewGrid, but because it is called outside of its parent form it doesn't seem to call the CellFormatting handle. I am trying to style the cells in code, but backcolor doesn't seem to do anything

'Create new form to display pnlPayment
 Dim FormPayment As Form = New Form
FormPayment.Size = New Size(1070, 652)
FormPayment.Name = "FormPayment"
FormPayment.StartPosition = FormStartPosition.CenterScreen
FormPayment.FormBorderStyle = FormBorderStyle.FixedDialog
FormPayment.ControlBox = False
FormPayment.Controls.Add(FrmCashRegister.pnlPayment)

'dynamically find this. can also be done with FrmCashRegister.pnlPayment.Visible = true but I wrote it like this to be sure and to make my life hard
Dim paymentpanel() As Control = FormPayment.Controls.Find("pnlPayment", False).

paymentpanel(0).Visible = True
FrmCashRegister.RadGridViewPayment.AutoSizeRows = True
FrmCashRegister.RadGridViewPayment.EnableAlternatingRowColor = True
For Each row As Telerik.WinControls.UI.GridViewRowInfo In FrmCashRegister.RadGridViewPayment.Rows
    For Each cell In row.Cells
        cell.Style.DrawFill = True
        cell.Style.ForeColor = Color.White 'works
        cell.Style.BackColor = Color.Blue 'doesn't work
    Next
Next

The cell.Style.ForeColor works, but cell.Style.BackColor does not.

Hello,

I have two problems with selfrefencing hierarchy in GridView. First, my test application is related to this thread, just for info and context, but I am asking question in new thread, as it was recommended to me, and I think this is separate problem not related to original design question.

https://www.telerik.com/forums/gridview---design-of-parameter-editor-with-subitems

I have created more realistic test application (TelerikTestReal in attached project) with new data structures for self referencing hierarchy binding. I can see desired output after program startup. When I add new main item programatically, GridView shows it properly. But, when I change test type of main item and subitems are changed, deleted child rows disappear, but newly added are not shown, as you can see on animation below. After some debugging, I see child rows are added to BindingList bound to DataSource of GridView, I also see ListChanged event of BindingList is properly fired, but GridView doesn't show new child rows. I can show them by calling ResetBindings() method of BindingList. What can be the problem?

The second problem is that I cannot close program after call to ResetBindings() method, I can click close button manytimes, but nothing happens.

Hi! 

My scheduler is in timeline view, and also grouped by resources. Is there a way to modify the day headers and add the name of the day itself there? (see picture attached)

Thanks!

Hello,

I have question about GridView handling of properties with Browsable(false) attribute. It's expected that when I add this attribute to some property, automatic generation of columns will ignore it. But why when I add this column manually, that column is empty. Is it a bug? I think that attribute means that should not be displayed in PropertyGrid, but it doesn't prevent to read / write property. It's not problem for me, that's just question, I ran into it during some other tests.

But, maybe it's not bug but expected behavior, but when I add this attribute to property used as ID for self referencing hierarchy, program freezes on startup, and I think this is a bug, isn't it?

Hello,

I am wondering if GridView really doesn't have selection mode similar to RowHeaderSelect in WinForms DataGridView, where I can select individual cells clicking on those cells or I can select row by clicking row header cell. I have read documentation and forum, and I am also wondering if somebody else really doesn't have the same question.

For example, I want to delete row only if row is selected, not if only few cells are selected in multiple rows, it's strange behavior for me. Or, second use case, I have more Copy operations depending on selection scope, if row is selected, whole data object is copied to clipboard, if individual cells are selected, just those data as text are copied, if only cells from specific columns are selected, one parameter sub-object is copied etc.

Now, I can get used to this new behavior, but users are used to DataGridView behavior, I think they will be little bit confused. Or, I know when I click to row header cell, all cells in that row are selected (also the hidden ones), so I can check if all cells in row are selected and then consider that row as selected, but it will be more processing.

I'm using Visualstudio2022 Dark theme on my program. When I load a fillable PDF to the PDF viewer, the back color of the form fields turns to black when I click on them. 

I tried changing the annotations color and the text color of the form fields, but nothing works.

How do I change the back color from black to white of the form fields on a fillable PDF? 

I need to create a grid that looks like this:

In the upper right there is an X that need to be a hyperlink which fires a C# event. I'm preparing the data for the grid like this:

foreach (var item in data)
{
    item.Name = $"<html><span style=\"font-size: 10\">{item.Name} {item.Acct}</span><p>{item.TicklerDesc}</html>";
    item.TicklerDate = $"<html><p></p><span style=\"font-size: 8\">{string.Concat(Enumerable.Repeat("&nbsp;", 22))}X<p></p>{item.TicklerDate}</span></html>";
}

As it stands now the X is useless. The questions is: How do I make it a hyperlink (or fake equivalent) so that I can fire a C# event?

Thanks

Hi,

I found how to put into radlabel a image here: https://www.telerik.com/forums/image-for-label and here is my code:

((TextPrimitive)this.lblTitle1.LabelElement.Children[2].Children[1]).Font = new Font("Roboto", 32, FontStyle.Bold);
ImagePrimitive imgPrimitive = new ImagePrimitive();
this.lblTitle1.RootElement.Children[0].Children.Add(imgPrimitive);
imgPrimitive.Image = WSResourceManager.UiImageProvider.InfoYellowIcon.Get(WSConfigurationManager.GetInstance.GetLargeIconSize());

Now I would like to align the image to the text that is centered (designer):

but as a result I get this (result):

How can I align this icon to the text?
