[Solved] Removing a Dock programmatically

Hello,

I've built a "portal" interface, combining dynamic TabStrip and RadDockLayout/Zone/Dock controls, fed from a database.

When the user clicks on a different tab, I want to show a different set of docks. On the postback, though, the docks from the soon-to-be-previous tab are still in viewstate and get reattached to their Zones. I added a method to clear them:

    
                ''' <summary> 
        
                ''' Clear all docks from a given raddocklayout 
        
                ''' </summary> 
        
                ''' <param name="rdLayout">given raddocklayout</param> 
        
                ''' <remarks></remarks> 
        
                Public Sub ClearAllDocks(ByVal rdLayout As RadDockLayout) 
        
                    Dim rdZones As ReadOnlyCollection(Of RadDockZone) = rdLayout.RegisteredZones() 
        
                    For Each rdZone As RadDockZone In rdZones 
        
                        rdZone.Docks.Clear() 
        
                        'For Each rdDock As RadDock In rdZone.Docks() 
        
                        '    rdDock.Closed = True 
        
                        'Next 
        
                    Next 
        
                End Sub

The .Clear() method isn't working. It just plain doesn't clear the Zone. The Docks are still there, before and after the .Clear() call.

I changed to the (commented out) .Closed = True option, but that seems slow and klunky to me.

a) is there a reason that .Clear() wouldn't work? I do realize I'm using a readonly collection to access them, but RegisteredZones only returns readonly.

b) is there a better way of clearing all the Docks in a Layout?

Thanks!

[Solved] GridEditCommandColumn and EditText

Hi All. Is it possible to change the EditText on a GridEditCommandColumn to a different value for each row? For example, I'd like to enter edit mode by click on a persons name. I'm doing all this in the code behind (C#). I can set the 'text' property but then I loose the link button. Thanks.

How can I can disable the zebra effect of a grid by setting the ClientSettings -> EnableAlternatingItems property of the grid to false

Hi,

I am using Telerik RadControls for ASPNET AJAX Q3 2008 on my current project.

I would like to disable the zebra effect on the grid on one of the web forms.

According to http://www.telerik.com/help/aspnet-ajax/grdcreatingnewskins.html I can do so by setting the ClientSettings -> EnableAlternatingItems property of the grid to false.

However the property does not seem to exist, and it is not possible to do this

1. At design-time as follows:

<telerik:RadGrid ID="radGrid" runat="server">

<ClientSettings EnableAlternatingItems="false">

<Scrolling UseStaticHeaders="true" />

</ClientSettings>

</telerik:RadGrid>

2. Programmatically as follows:

this.radGrid.ClientSettings. EnableAlternatingItems = false;

Can you please tell me how to do this?

Thanks & regards,

Herman Gouw

Chart :: Display

Hi ,

I have a pie chart containing large amount of data, thus when the chart is rendered the labels overlap each other (see attached image). So, how can I show label of pie slice so it appears readable ? Is there any way to provide line connectors from pie slice to Labels…or may be something similar to this?

The project is being developed in asp.net 3.5 with C# as scripting language.

Your quick response will be appreciated.

RadFileExplorer - Delete & Upload Paths do not display

It was not clear to me, but apparently the "UploadPaths" and "DeletePaths" must be directories under the "ViewPaths" directory. I could not get the other two directories to display until I made the "ViewPaths" directory the parent of the other two.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

'/==> Directory structure (?)

'/==>~/App_Files/

'/==>~/App_Files/App_Views/

'/==>~/App_Files/App_Uploads/

'/==>~/App_Files/App_Deletes/

Dim sPath1 As String = "~/App_Files/" '/==>Parent directory (Views)

Dim sPath2 As String = "~/App_Files/App_Uploads/" '/==>Child of Parent (Uploads)

Dim sPath3 As String = "~/App_Files/App_Deletes/" '/==>Child of Parent (Deletes)

Dim saViewPaths As String() = New String() {sPath1}

Dim saUploadPaths As String() = New String() {sPath2} '/==>or {sPath2, sPath3}

Dim saDeletePaths As String() = New String() {sPath3} '/==>or {sPath2, sPath3}

rfe1.Configuration.ViewPaths = saViewPaths

rfe1.Configuration.UploadPaths = saUploadPaths

rfe1.Configuration.DeletePaths = saDeletePaths

rfe1.Configuration.SearchPatterns =

New String() {"*.*", "*.JPG"}

rfe1.Grid.Columns(1).HeaderStyle.CssClass =

"sizeColumn"

End Sub

Maybe, it will save someone else a little time.

Spell Check script errors due to <% ... %>

I am trying to add the Rad Spell check to a RadTextBox. I followed the instructions carefully and have succes IF I create a page with just the javascript SpellcheckDone function and the RadTextBox and the RadSpell. If, however, I add this code to an existing page, it will build with no errors; but when I try to bring up the page with the spell check javascript function on it, I get the following error:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Nevermind ... I finally figured out that the RadCodeBlock could go around the <script></script> code; and then it works without errors.

ComboBox DropDown - items overflowing; scrollbar missing (IE8)

Hello,

I have 2 comboboxes with the same skin, height, and other attributes.
ComboBox 1 : on page 1, inside a radwindow
ComboBox 2 : on page 2, on a normal page

ComboBox 1's items spill out of the drop down, and there is no scrollbar.
ComboBox 2 works fine.

At first I thought it might be something to do with the radwindow, but when I opened that page (page 1) in just a browser window, the problem's still there.

Page 1 and page 2 are quite different however... May I know what possible causes are for this issue so I can track it down?

Screenshot attached.

PS:
Came across this upgrading from Q3 2008 to Q3 2009... This is not a problem with Q3 2008 on IE8
This is not a problem on IE7 or Firefox.. Haven't confirmed on other browsers yet

Thanks!

Problem with RadGrid not updating

Hi,

I have a RadGrid that I am manually controlling data for using the NeedDataSource event. Everything has been working fine, until I added a RadComboBox outside of the grid which allows the user to select a value for filtering the grid. I'm calling Rebind() to re-query my data, and it's calling NeedDataSource correctly. I query my data, bring back new values based on the filter, and assign it to the DataSource property of the grid. However the grid display never updates so the user is left seeing the records from before the filtering.

Any ideas?

Thanks,
Neil.
