How to change the text of Total-Summary-Row?

Hi!

I use grouping with summaryrows in each group and set ShowParentGroupSummaries in the MasterTemplate = true.
Also I set MasterTemplate.ShowTotals = true.

In the first column, the Total-Summary-Row is titled with the last-item-text of the last group ;-(.

How can I change this text to "Total" (for examle)?

Kind regards

Michael

Maximized ShapedForm not larger than screen size.

This would be a really cool feature - by convention, I would expect a maximized ShapedForm to fit inside the screen.

You can hack it, but I can't see any purpose for a form to be larger than the screen.

Maximized ShapedForm larger than Screen

Hi,

This may seem a pretty dumb question to ask, but how do you restrict a maximized ShapedForm so that it only occupies the screen space?

Eg, when it's maximised, it's about 10pixels too large on every size, and the close button is clipped. I added 10px of padding, but it looks stupid when the form is in a normal state. Ideally, I am looking for a form which behaves like a normal form, but has rounded edges.

I'm running on Vista 64-bit w/ multiple monitors - maybe this is platform specific? The sample applications also experience this issue.

All suggestions are welcome...

Regards,

Matt

Radiobutton in Detail page

I implemented the example in the GridView >> Hierarchy >> Tabbed Views (CustomDetailViewCellElement)

One of the tabs is a grid and I need a mutually exclusive radio button to indicate which record is the primary.

I try this thread but it only works if there are no hierarchy: http://www.telerik.com/community/forums/winforms/gridview/radiobutton-in-radgridview.aspx#1601100

I thought changing this part of the code to this would work but it doesn't either:

Private Sub radioButtonElement1_MouseDown(sender As Object, e As System.Windows.Forms.MouseEventArgs)

Me.Value = 1

If Me.ViewTemplate Is GetType(Telerik.WinControls.UI.MasterGridViewTemplate) Then

For Each row As GridViewRowInfo In Me.ViewTemplate.Rows

If row IsNot Me.RowInfo Then

row.Cells(Me.ColumnInfo.Name).Value = 0

End If

Next

Else

For Each row As GridViewRowInfo In Me.ViewInfo.Rows

If row IsNot Me.RowInfo Then

row.Cells(Me.ColumnInfo.Name).Value = False

End If

Next

End If

End Sub

Any ideas????

Change column background color

Hello
I'm using the code below to change the background color for a column in my grid.

With this I expected, after populating my grid with data (it is databoud to a datatable), that column "MyColumnName" will show all his cells backgroud in yellow color.

What I get is that I see the cells with the default background color (I'm using Office 2010 Black theme for the entire application), and I only see this column in yellow if I move the mouse over one row (when it highlights) in the column "MyColumnName" in this row alone. All the rest keep the default color.

Is there something I'm missing or doing wrong? I'm using Q2 2012.

Thank you in advance.

Private Sub MyGrid_CellFormatting(sender As Object, e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles MyGrid.CellFormatting

If e.CellElement.ColumnInfo.Name = "MyColumnName" Then

e.CellElement.BackColor = Color.Yellow

Else

e.CellElement.ResetValue(VisualElement.BackColorProperty, ValueResetFlags.Local)

End If

End Sub

RadDateTimePicker behaviour...

Hi there,

Just a comment really, when using a rad datetime picker, it might be useful to be able to catch some event based on the date that a user has selected.

The problem is that with the select/unselect behaviour of the calendar in the datepicker, there is an inbetween event "valuechanged" fired, with the date at that point being "1 January 1980", or datemin, so you can't really attach anything directly to that event without fudging it...

Now I understand the select/unselect of a calendar is why this behaviour exists, but realistically, when using a datepicker control, WHY would anyone want that inbetween date? Surely we're only ever interested in the date that the user has selected? This feels to me like seeing unecessarily the mechanics of the control?

Would it not be possible to segregate the events into a "real" ValueChanged event which would only fire once the

transaction (if you like) of changing to mindate and then to the actual date clicked on had completed and then relegate the current ValueChanged to something more accurate like "CalendarSelectionChanged"?

I think that a datepicker control should allow me to capture what the user has actually selected without having to filter out spurious events.

Incidentally, how DOES one filter out that spurious event when the date selected happens to be the minimum date? Does your control fire valuechanged twice, both times with the same (mindate) value in the Value property?

Kind regards,

Mike

GridViewDateTimeColumn - how to edit time AND date

Hello, I'm trying to make date and time both editable in a GridViewDateTimeColumn. I declare a column with this code:

column = new GridViewDateTimeColumn(def.Name);

string dataFormatString = (def.CustomString == null ? "yyyy-MM-dd hh:mm:ss" : def.CustomString);

((GridViewDateTimeColumn)column).EditorType = GridViewDateTimeEditorType.TimePicker;

((GridViewDateTimeColumn)column).FormatString = dataFormatString;

((GridViewDateTimeColumn)column).CustomFormat = dataFormatString;

I tried DateTimePicker and TimePicker alike.

In DateTimePicker the time is always 12:00. If I want to edit the field with keyboard only (no additional window) I only see the date in the editbox, the time vanishes on edit mode. In TimePicker I can edit date in edit mode.

My questions are:
1) How to make time editable in DateTimePicker?
2) Is there a WinForms control that allows editing date and time in additional window mode?

Thank you in advance for your answers.
Best wishes,
Mariusz
