SelectionOnFocus

Problem in 2009.3.1210.35

I have RadTextBox without specifying SelectionOnFocus but it seems it's behaving like as if SelectionOnFocus is set to CaretToEnd.
Setting SelectionOnFocus to None does not fix the issue.

Update: Problem is fixed in 2009.3.1503.35 .

[Solved] RadGrid - issue with PageSize

Hi guys,

I have a radgrid with shows the page size at the bottom, allowing users to change it to various values.
If my grid has let's say 7 items in it and the page size is 5 then everything works. If I then change the page size to 10, the grid will show all items but the pagesize dropdown dissapears completely. How can i make sure it is always displayed ?

RadDock <%= Problem

Hello,

This is an interesting problem i think. We are taking "The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)." error. We have a code block like this:

<table>

<tr>

<td>

<%="Example Here" %>

</td>

</tr>

</table>

<telerik:RadDockLayout runat="server" ID="rdlGallery" OnSaveDockLayout="rdlGallery_SaveDockLayout" OnLoadDockLayout="rdlGallery_LoadDockLayout">

<telerik:RadDockZone runat="server" ID="rdzGallery" Width="600" MinHeight="100" Orientation="Horizontal"></telerik:RadDockZone>

</telerik:RadDockLayout>

client side grouping/filtering

Hi,

I'm working on implementing a scheduler/clock in&out system.

I'm binding client side through web services to a scheduler grouped by Users (so I have multiple columns one for each employee and in those columns I'm displaying their clock in and outs).

I want to implement a filter so you can view 1,2,3,4 etc users at a time instead of all of them. I have a multi-select combobox above the scheduler which I grab the values from client side then do a client side rebind and capture the OnClientAppointmentsPopulating event then override the SchedulerInfo class to pass an extra parameter (the users which I want to view) and then store that in the session and access it in the controller.

This is all working fine and when I do the filter I can see that only the data for the particular users is returned and the appointments for the other users disappear from the calendar BUT the columns for each user (resource) are still there just empty with no appointments since I filtered those out. Is it possible to hide those empty columns as well so those users do not show? Is this possible client side? Not even sure I think I may be asking for too much...

I attached a picture to clarify what I'm looking for...each user has their own column...I want to be able to filter the data (got this part working) and only show 1-2 columns at a time (not working after I get filtered data all columns stay just appointments disappear)

How to add Sorting & Filtering to this Grid

I have just implemented CustomPaging to my RadGrid, but now I seem to have broken sorting and filtering, as well as the fact that I can't get it to display the records in REVERSE order straight from the db (99,98,97,etc... the Order By [errDate] Desc doesn't seem to be doing exactly what I'm looking for).

Here is my Grid

    
            <telerik:RadGrid ID="RadGrid1" PageSize="15" AllowFilteringByColumn="true" runat="server"

                        AllowAutomaticInserts="false" AllowSorting="true" AllowPaging="true" AllowCustomPaging="true" 
        
                        OnNeedDataSource="RadGrid1_NeedDataSource"> 
        
                        <MasterTableView TableLayout="Auto" DataKeyNames="ID">

Any advice on this would be greatly appreciated, thanks.

Programmatically created RadGrid - Paging not working

I am using the following code:

                                        o_Grid.ShowStatusBar = o_Table.Rows.Count > 10 
        
                                        o_Grid.Width = Unit.Percentage(100) 
        
                                        o_Grid.RegisterWithScriptManager = True 
        
                                        o_Grid.EnableEmbeddedScripts = True 
        
                                        AddHandler o_Grid.NeedDataSource, AddressOf _GridsNeedDataSource 
        
                                        AddHandler o_Grid.PageIndexChanged, AddressOf _GridsPageIndexChanged 
        
                                        AddHandler o_Grid.ColumnCreated, AddressOf _GridsColumnCreated 
        
                                        Debug.WriteLine(String.Format("Grid.UniqueID: {0}", o_Grid.UniqueID)) 
        
                                        o_SerialNumbers.Controls.Add(o_Grid) 
        
                                        o_Proxy.AjaxSettings.AddAjaxSetting(o_Grid, o_Grid)

to dynamically, programmatically add a number of different grids to a Web Content Form during the Page_Load

Fine and dandy.

The Initial .NeedDataSource is fired and the grids are populated correctly, paging enabled/disabled etc.
Here comes what I have not been able to get to work.

Once I click the page "2" button or the "next page" etc ... the AjaxRequest fires correctly but no NeedDataSource or PageIndexChanged ... I can't wrap my head around it.

Bout the second problem I've had in 5y of using Telerik and not being able to figure out a solution by reading the documentation, forums, kb etc.

Anybody have any idea ?

o_Proxy = RadAjaxManagerProxy
o_SerialNumbers = RadAjaxPanel

[Solved] Date guessing

Hello,
If I enter "30/22/09" into the first control in this demo, it gets updated to be "9/30/2022" rather than displaying an error indicating the date is invalid. If I enter "9", it gets changed to "8/9/2009". Is there a way to disable this and just show this as an invalid date?
Thanks

Window over java applet problem

I am having a problem overlaying the RadWindow on top of a mapping java applet in Firefox and Chrome (it works OK in IE). The behaviour showing is that the border of the frame is hidden behind the applet but the content of the window is showing correctly. I have tried playing with the z-index of various css classes such as ".RadWindow .rwTopResize" but without success.

Any help in getting around this would be much appreciated.

Thanks in advance, Carl

AjaxManager causes error when using System.Web.Caching.Cache property

Hi everyone

I'm fighting with this issue for quite a long time now, and so I thought this would be the right place to ask a question regarding this little issue.

Every time I try to cache data with the System.Web.Caching.Cache property, I get the 'Controls cannot be ajaxified after Page PreRender.'-error at the line where I call AddAjaxSettings on the RadAjaxManager. When I remove the caching lines, everything just works fine. I sincerely do not know why the usage of the Cache property causes the AjaxManager to throw an exception.

The following describes the faulty scenario:

I have a RadTreeView in the Master page. When a node of it is dropped, some data I want to cache is loaded into a RadGrid which is placed in the Default.aspx page. After this step the thing crashes (the first time - the data is not in the cache yet - it loads the data into the grid; the second time - data is in the cache now - it throws the abovementioned exception). The caching code is actually very simple:

                    BindingList<string> strings = Cache["LotsOfItems"] as BindingList<string>;         
            if (strings == null)         
            {         
                strings = MyClass.GetLotsOfStrings();         
                Cache.Insert("LotsOfItems", strings, null, DateTime.Now.AddMinutes(1), Cache.NoSlidingExpiration);         
            }         
                     
            myGrid.DataSource = strings;         
            myGrid.DataBind(); 
            
                    

I hope somebody can help me out with this one. I'll provide further information if needed.

Thanks very much.

Kind regards,

Mallory
