[Solved] Hide RadPanelGroupBarElements

Hi,

Is there a way to hide some of the GroupBarElements in a PanelBar and have the remaining GroupBarElements reposition themselves accordingly?

For example, I can get the first 3 GroupBarElements to hide using the Visibility property, however the 4th GroupBarElement will appear where it would be if the 3 first buttons were still visible. I'd like the 4th GroupBarElement to appear on top when the previous 3 are hidden.

Odd borders and sizing problems

Hello,

Neat control in the demos, but when I come to use it I have some problems. The carousel is inside a splitter panel that is 50% tall and 25% wide of the form.

1) I am loading images at runtime from the sample pictures folder (C:\Users\Public\Pictures\Sample Pictures), these are much larger than the control. I had expected there to be a means to say autosize the image but the autosize property on the carousel item does not appear to do anything.

2) The images are not centered (see attached) nor can I figure out where the borders are coming from.

3) I cannot move the navigation buttons, I want them as they are but half way up (I'm surprised this is not a provided setting).

4) The MSDN documentation is awful, look at the description of the easing types for example: ms-help://MS.VSCC.v90/MS.VSIPCC.v90/telerik.winforms.2010.2/telerik.winforms/Telerik.WinControls~Telerik.WinControls.RadEasingType.html

On re-sizing the splits it seems that image is probably the right size but the borders are messing things up.

All I am after is a slide show. maybe this is not the appropriate control?

Here is my code:

Dim objl_TELERIK_CAROUSEL As New Telerik.WinControls.UI.RadCarousel

ctll_PANEL_3.Controls.Add(objl_TELERIK_CAROUSEL)

objl_TELERIK_CAROUSEL.Dock = DockStyle.Fill

objl_TELERIK_CAROUSEL.Name = ctll_PANEL_3.Name & "_TELERIK_CAROUSEL"

objl_TELERIK_CAROUSEL.AnimationsToApply = Telerik.WinControls.UI.Animations.None

objl_TELERIK_CAROUSEL.AnimationDelay = 0

'objl_TELERIK_CAROUSEL.AnimationFrames = 0

objl_TELERIK_CAROUSEL.EasingType = Telerik.WinControls.RadEasingType.Default

objl_TELERIK_CAROUSEL.ItemReflectionPercentage = 0

objl_TELERIK_CAROUSEL.AutoScroll = False

objl_TELERIK_CAROUSEL.ButtonNext.Location = New System.Drawing.Point(objl_TELERIK_CAROUSEL.ButtonNext.Bounds.X, CInt(objl_TELERIK_CAROUSEL.Height / 2))

For Each strl_FILE As String In My.Computer.FileSystem.GetFiles("C:\Users\Public\Pictures\Sample Pictures")

  If strl_FILE.EndsWith(".jpg") Then

    Dim carouselItem As Telerik.WinControls.UI.RadButtonElement = New Telerik.WinControls.UI.RadButtonElement

    carouselItem.Image = New Bitmap(New Bitmap(strl_FILE), objl_TELERIK_CAROUSEL.Size.Width, objl_TELERIK_CAROUSEL.Size.Height)

    carouselItem.Alignment = ContentAlignment.TopLeft

    carouselItem.DisplayStyle = Telerik.WinControls.DisplayStyle.Image

    carouselItem.FitToSizeMode = Telerik.WinControls.RadFitToSizeMode.FitToParentBounds

    carouselItem.ImageAlignment = ContentAlignment.TopLeft

    carouselItem.AutoSize = True

    carouselItem.AutoSizeMode = Telerik.WinControls.RadAutoSizeMode.Auto

    objl_TELERIK_CAROUSEL.Items.Add(carouselItem)

  End If

Next

RadCalendar SpecialDays Remove

I tried to remove my SpecialDays by using functon 'RadCalendar1.SpecialDays.Remove(mday)
but it seems doesn't working

Private Sub RadButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadButton1.Click

Dim mdate As New Date

mdate = RadCalendar1.SelectedDate

Dim mDay As New Telerik.WinControls.UI.RadCalendarDay(mdate)

RadCalendar1.SpecialDays.Add(mDay)

End Sub

Private Sub RadButton2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadButton2.Click

Dim mDay2 As New Telerik.WinControls.UI.RadCalendarDay()

mDay2.Date= RadCalendar1.SelectedDate

           mCalendarDay.Date.ToString("dd/MM/yyyy")

RadCalendar1.SpecialDays.Remove(mDay2)

End Sub

I wonder if its datetime format cause the problem?...cos it seems if i select a date e.g. '07/08/2010' (I am using en-GB format) it automatically covert it to US Datetime format when you try to remove it (Like '07/08/2010' will become '08/07/2010') , the system wouldn't throw any error, but this special day still in 'Radcalendar1.specialdays 's' List. can anybody please give me example code how to remove certain specialdays by code?
btw, the version i got is "2009.1.9.414"
thanks in advance! its urgent.

How to release memory when RadDock is created on PageViewPage?

Hello Team Telerik,

This is very likely a simple question to answer:

My test winforms application (Telerik Winforms components Q2 2010) has one RadPageView component on Form1. Each Button1 click will create a new PageViewPage and put a RadDock on it (see code below). Running this app from within VS2008 will show in Windows Taskmanager (Windows 7 32 bit) after the application-start approx. 40MB memory working set. Clicking 20 times on Button1 will increase the memory to approx 80MB. Closing all pages by clicking on the X button of the PageView TabStrip will not reduce the amount of used memory (instead creating another set of 20 pages by clicking Button1 will result in further increased memory allocation).

namespace WindowsFormsApplication4

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void button1_Click(object sender, EventArgs e)

{

RadPageViewPage page = new RadPageViewPage();

page.Text = "Page";

RadDock dock1 = new Telerik.WinControls.UI.Docking.RadDock();

dock1.Dock = System.Windows.Forms.DockStyle.Fill;

page.Controls.Add(dock1);

this.radPageView1.Pages.Add(page);

this.radPageView1.SelectedPage = page;

}

Trying to remove dock1 from the page and disposing it when the page is removed did not help:

private void radPageView1_PageRemoving(object sender, RadPageViewCancelEventArgs e)

{

RadDock dock1;

RadPageViewPage page = this.radPageView1.SelectedPage;

if (page != null)

{

Control[] pagecontrols = page.Controls.Find("radDock1", false);

int numerofpagecontrols = pagecontrols.Length;

if (numerofpagecontrols == 1)

{

dock1 = (RadDock)pagecontrols[0];

page.Controls.Remove(dock1);

dock1.Dispose();

}

Thank you very much for any feedback.
Regards,
Ralf

Setting RadDropDownList to NoSelection in code

Hello everybody.

I have a problem with rad drop downlist.
My drop down list is unbound and populated during runtime, every item having text and value.
A valid value to be displayed should be 'no selection' => SelectedValue = null
The selected item should change after the selected node in a tree view is changed

When I first select item which have null as value for the drop down list, everything's ok.
But after an entry from the DrowDownList was selected and the try to change the SelectedValue to null, I have the problem, that even though the SelectedValue seems to be null, the text of the last selected item is still displayed.

I tried setting the value to NULL by using:

SelectedValue = null;
SelectedIndex = -1;
SelectedItem = null;

All produced the same result: The SelectedValue is null when I check, but there is still text displayed.
So, my question is: how can I reset the DropDownList to a state where no item is selected by code.

Thanks for any help

Cell Editing Events

Hi,
I have a gridview with rows added at runtime. i have some 5 radcheckbox columns. I wish to detect changes made to checkbox columns. i.e checked state.
I am trying to use the cell_beginedit and cell_endedit events.
I am using 2010 Q1

Problems:
Begin event fires perfectly on first checkbox checked state change. After the event finishes the end event must fire. It only fires whence i change checked box state in another row. else on the same row same checked box cell it wont fire. If i change state of a checkbox cell continuosuly , the beginedit event only fires the first time, next time it doesn't fires because the editor hasn't ended.

I tried to close the editor myself in the begin edit event but nothing happens.

void gvLiveCnns_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)

{

// Do some work, cancel event if work not performed as expected

this.gvLiveCnns.EndEdit();

this.gvLiveCnns.ActiveEditor.EndEdit();

this.gvLiveCnns.CloseEditor();

}

Any solution to this problem. Please provide a solution using this event only as i wish to cancel out editing event if worked not performed as expected.

Thank you.
