Open several winforms on dock

Hi there,

I'm pretty new with Telerik and have a question. I have a RadDock1 on a form. On that form there is also a button. Every time the users clicks this button I want to create a new tab on RadDock1 filled (maximized) with a (win)Form (named "frmProject").
I've created a sub "AddPage":

    
                Private Sub RadButtonElement1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadButtonElement1.Click  
        
                    AddPage(frmProject, "Project")  
        
                End Sub 
        
                Private Sub AddPage(ByVal f As Form, ByVal strPage As String)  
        
                    RadDock1.DockControl(f, DockPosition.Fill, DockType.Document)  
        
                End Sub

The first time the user clicks the button a new tab is added with the form filled on it. But the second time the user clicks the button only a tab is added. I can't see the form.

Can you please tell me what I am doing wrong?

Kind regards,
Ronald

RadListBoxItem Height

We have a RadListBox populated with about 10 items.

The initial display is fine, but when we scroll down to see further items the height of each item is altered.
In the attached file the first image shows the correctly diplayed RadListBox. The second image shows the result of scrolling down only one item.

Worse: the scroll bar has not compensated for the altered height of each item so that it is impossible to scroll further down to the end of the list.

We have tried the following, but nothing works:
i. forced the items to not TextWrap,
ii. populate items with no image

Is it possible to prevent this behaviour?

Thanks in advance.

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

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
