GridView selection mode similar to RowHeaderSelect in WinForms DataGridView

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.

HTML hyperlink in cell to fire C# event

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>{item.Name} {item.Acct}{item.TicklerDesc}</html>";
item.TicklerDate = $"<html>{string.Concat(Enumerable.Repeat(" ", 22))}X{item.TicklerDate}</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

Can't change back color of RadGirdView from other form

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.

I've tried getting the CellElement and assigning styling there but that doesn't work either.

RadRibbon split button image/text alignment

Hi there,

I have a RadRibbonBar which contains a RadSplitButton element and I'm using Windows11Compact Theme.

I have set splitBtn.ArrowPosition = Bottom and ImageAlignment and TextAligment = TopCenter.
I want the image and text to be centered on the button but they are both aligned right. I notice this only happens with the Windows11 themes, and only to the RadSplitButton. The DropdownButton image/text is correctly centered, however I need to use the split button as there is an event triggered when the button portion of the control is clicked.
I have tried searching for other alignment properties in the UI Elements and setting them all to TopCenter but that still does not solve the problem.

Is this the expected behaviour/appearance? And is there a way I can have the image and text centered on the control?

I have attached a screenshot of the issue I am experiencing.

Thank you,
Carmen
