How can I size a RadPanelBarGroupElement with a splitter?

Greetings,

I have a RadDockPanel with a RadPanelBar on it, with multiple RadPanelBarGroupElements on the RadPanelBar. I'd like a horizontal splitter between each RadPanelBarGroupElement (as exists between/attached to multiple DockPanels for example, making each dock panel sizable)...So I can allow the user to size each RadPanelBarGroupElement...as well as collapse them which i'm currently allowing...

Thoughts?

Thanks,
GBute

[Solved] radThemeManager seems to store file path of development machine.

Hi
I created a custom theme file MyCustomBreeze1.xml . In one form i drag and drop radThemeManager and in "loadedthemes" property I added a Themesouce and selected a file from location C:\Trials\Components\MyCustomBreeze1.xml

When we compile and run the applicationl, things looks working and theme is applied to grid control.

But when i publish the project using click once and deploy it on "Test" machine, theme does not work. it looks like radThemeManager is looking for path C:\Trials\Components\MyCustomBreeze1.xml on "TEST" machine.

How to resolve it ? Is there a way i can load theme dynamically at runtime from XML file and apply it to a particular control ?

Is there a way to sort (numeric) strings like numbers?

Hello,

I have a TextColumn in my grid that contains numeric data.

I don't want to change it to a DecimalColumn...

When I sort, it's sorted only concerning the first digit, because it is text.

Is there a way to convert it to numeric data for sorting in my Sorting Expressions?

If not: How can I add an empty value to a DecimalColumn by using a value Array?

Best regards.

Page Up Down Listbox

I am trying to achieve a page up/down functionality for a Point of sale.

Lets say the case where i have a listbox
Achored on all sides, and autoscroll enabled = true

with two bottons Page up / Page down

If I press page down button I want the list box to scroll down by the amount of its height.
How do I do this ?

I tried using for page down

radListBox1.AutoScrollOffset = new Point(0, (-1*radListBox1.AutoScrollOffset.Y)+radListBox1.Height);

I use a positive value for y point because it gets converted into negative and therefore I set the Y offset to a positive by multiplying it by -1.

With very little success.

Thank you in advance

Multiple questions on GridView

We have been evaluating the GridView for several weeks now and now we have a couple of questions which hopefully somebody can answer

Extending the Context Menu

We have added some extensions to the context menu . However we need to change the Menu Label based on a event click. So far we have not been able to do that. Is that possible ?

Parent/Child Grids

We have a parent child relationship inside a Grid. The grid populates correctly the first time and then we change some of the data in the Child Grid. This causes the Grid to not show any data anymore. Any ideas ?

Saving Preferences

We would like the users to be able to save and store their preferences for the following

1. Column Positions
2. Grouping Preferences
3. Sort Preferences
4. Conditional Formatting Rules

Is this possible

Conditional Formatting based on values in other columns

We would like the user to be able to setup Conditional Formatting rules where the rule is based on another column For eg:- if Shipped Qty > Req Qty (where both these fields are columns of the Grid) then apply the formatting rule.

Is this possible

Icons

I'm playing around with the ribbon bar, trying to recreate the look of our app with your controls.

Anyway our current ribbon bar uses Icons (.ico) files

I tried adding the .ico to your ribbon bar (.ico wasn't a default extension for an image but I tried it anyway) It crashed the designer. Something about transparency and bitmaps. Anyway I couldn't figure out how to recover so I shut down visual studio and restarted. So I ended up losing my changes, is there anything I can do if this happens in the future?

Anyway I converted them to PNG's and they seem to work fine.

Just wondering in the future if .ico should be supported, or if I need to convert them?

Thanks

Vertical scrollbar doesn’t appear in ToolWindow

Good morning.

I have a problem with the vertical scrollbar in a toolwindow. I use your RadControls for WinForms Q3 2009 release. I did the following steps:

New project, WindowsForm Application (with Visual Basic 2008 Express Edition).
Insert a RadDock, “Dock new window to left”. This is ToolWindow1.
Insert a radPanelBar in the toolwindow, dock = fill, groupstyle = explorerBarStyle.
By clicking on a button, the radPanelBar is programmatically filled with RadPanelBarGroupElement:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

RadPanelBar1.Items.Clear()

For i As Integer = 0 To 10

Dim ri As New Telerik.WinControls.UI.RadPanelBarGroupElement

ri.Caption = "GroupItem" & i

RadPanelBar1.Items.Add(ri)

If the form is small enough, you can see that no vertical scrollbar appears. As soon as you click on a groupitem, the scrollbar appears. If you click the button again, again the scrollbar disappears. What can I do to solve this problem?

Thank you.

RadProgressBar on MDIParent not updating when called from MDIChild

Hi,

I'm trying to update/show the status of a task which loads values from a database into a ComboBox, but the StatusStrip on the MDIParent is not updating to reflect this.

The code extract with relation to this task is as follows. I have put the database loading to a ComboBox in it's own BackgroundWorker to assist, but still no luck.

Code as follows:

    
                Private Sub frmTradingApplication_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
        
                    'START: Set Theme for all Telerik Controls

                    'END: Set Theme for all Telerik Controls

Themes and Telerik CAB supporting RadDock???

Hello everybody,

we are using Telerik CAB Enabling Kit for RadControls for WinForms and RadControls Q1 2010 SP2 in our application. When I try to apply any of the provided themes, the TabStrip of the dockingmanager does not look very well - it is absolutely different from any other TabStrip (except when using the theme called "Telerik") + some(!!!) menu entries are shown with white fontcolor after appliing "Aqua" - Theme and then "Breeze".

I found this blog entry http://blogs.telerik.com/blogs/posts/09-06-26/meet_the_new_raddock_for_winforms_%E2%80%93_official_version_coming_with_q2_2009.aspx .

"Jordan" answered: "Yes, Miguel, we will rework the Telerik CAB Kit and the sample CAB application to work with the new RadDock component. Expect this to happen around Q2 SP1, which is 4-5 weeks away." on 30 Jun 2009, but as I could see, it did not happen yet!!!

So how can I use Telerik Themes with Telerik CAB??? OR
How long does it take, rework the Telerik CAB Kit and the sample CAB application to work with the new RadDock component???

Thanks for your help,
Thomas
