[Solved] FIX: Javascript error on mouse over a tab next to a separator (Q3 2009)

Problem
When you hover a tab which is a sibling of a separator tab (IsSeparator=True) you get a javascript error:

"className" is null or not an object

Who is affected
Everyone who uses Q3 2009 version (2009.3.1103) and have IsSeparator = True set for any of the tabs.

Workaround
Place the following javascript code right after the script manager's declaration:

    
            <script type="text/javascript"> 
        
            Telerik.Web.UI.RadTab.prototype._highlight = function () 
        
            { 
        
                if (this.get_hoveredCssClass()) 
        
                    Sys.UI.DomElement.addCssClass(this.get_linkElement(), this.get_hoveredCssClass()); 
        
                var prev = this.get_previousTab(); 
        
                var next = this.get_nextTab(); 
        
                if (prev) { 
        
                    var prevLink = prev.get_linkElement(); 
        
                    if (prevLink) 
        
                        Sys.UI.DomElement.addCssClass(prevLink, "rtsHoverBefore"); 
        
                } 
        
                if (next) { 
        
                    var nextLink = next.get_linkElement(); 
        
                    if (nextLink) 
        
                        Sys.UI.DomElement.addCssClass(nextLink, "rtsHoverAfter"); 
        
                } 
        
                if (!this.get_enabled()) return; 
        
                if (!this.get_hoveredImageUrl()) return; 
        
                if (!this.get_imageElement()) return; 
        
                if (this.get_imageElement().src != this.get_hoveredImageUrl()) 
        
                    this.get_imageElement().src = this.get_hoveredImageUrl(); 
        
            }; 
        
            Telerik.Web.UI.RadTab.prototype._unhighlight = function () 
        
            { 
        
                if (this.get_hoveredCssClass()) 
        
                    Sys.UI.DomElement.removeCssClass(this.get_linkElement(), this.get_hoveredCssClass()); 
        
                var prev = this.get_previousTab(); 
        
                var next = this.get_nextTab(); 
        
                if (prev) { 
        
                    var prevLink = prev.get_linkElement(); 
        
                    if (prevLink) 
        
                        Sys.UI.DomElement.removeCssClass(prevLink, "rtsHoverBefore"); 
        
                } 
        
                if (next) { 
        
                    var nextLink = next.get_linkElement(); 
        
                    if (nextLink) 
        
                        Sys.UI.DomElement.removeCssClass(nextLink, "rtsHoverAfter"); 
        
                } 
        
                this._updateImage(); 
        
            }; 
        
            </script>

[Solved] secong level of RadWindow bigger than First Level

Hi,

I have a scenario like this. I open a small modal RadWindow of the size(300,400) from the ContextMenu of the Radgrid. I want to open a second RadWindow (size maximum possible as per the window size and resolution) when I click on the link in the first RadWindow. As I understand, when I open the second radWindow from first one, the second window is always within the first window, is it possible to open the second RadWindow with maximum screen size possible?

I am using following Javascript code to get the screen width and height and want to open the second RadWindow with this size.

w = window.screen.availWidth;

h = window.screen.availHeight;

Thanks.

Dynamic RadDock-structure only keeps track of non-dynamic RadDockZone

I have a .aspx page where I have a RadDockLayout and a RadDockZone registered as this:

    
            <telerik:RadDockLayout ID="rdlDockLayout" runat="server" OnLoadDockLayout="rdlDockLayout_LoadDockLayout" 
        
                OnSaveDockLayout="rdlDockLayout_SaveDockLayout"> 
        
                <telerik:RadDockZone ID="rdzMain" UniqueName="rdzMain" runat="server" MinHeight="600px" 
        
                    Width="550px" BorderStyle="None"> 
        
                </telerik:RadDockZone> 
        
                <div style="display: none"> 
        
                    <%--Hidden UpdatePanel, which is used to receive the new dock controls.--%> 
        
                    <%--We will move them with script to the desired initial dock zone.--%> 
        
                    <asp:UpdatePanel runat="server" ID="udpPanel" OnLoad="udpPanel_Load"> 
        
                        <Triggers> 
        
                            <asp:AsyncPostBackTrigger ControlID="cmdNewDockWithZone" EventName="Click" /> 
        
                            <asp:AsyncPostBackTrigger ControlID="cmdNewDock" EventName="Click" /> 
        
                        </Triggers> 
        
                    </asp:UpdatePanel> 
        
                </div> 
        
            </telerik:RadDockLayout>

I'm adding new Docks to the page via the UpdatePanel and placing the using script as illustrated in this example. Some docks are created with a DockZone and some are placed in these dynamically created DockZones.

Now I want to be able to react to the placed docks from code behind during the AJAX call backs but it seems that the DockZones are "lost" after they have been created. I.e. only the non-dynamic DockZone (rdzMain) is registered in rdlDockLayout.RegisteredZones and when calling rdlDockLayout.GetRegisteredDocksState() all Docks that are docked in dynamically created DockZones have an empty string for DockZoneID. This makes it hard to figure out which Dock belongs to which DockZone, which is important to my application.

DockZones have the same string (unique per DockZone though) set as both ID and UniqueName.

Is something wrong or is this the expected behavior when creating DockZones dynamically?

[Solved] Key Value In LinqDataSource Selecting Event.

In FormTemplate I place combobox that select value from LinqDataSource, I want to find Selected Row’s Key value inside Linq’s selecting event at server side that will fire when user click on Add/Edit row in grid.

My code is.

<asp:LinqDataSource ID="linq_Students" runat="server"

ContextTypeName="dbLibrary.StudentDataContext"

TableName="tbl_Students" OnSelecting="linq_Student_Selecting">

</asp:LinqDataSource>

<telerik:RadGrid ID="gv_Student" runat="server"...

<MasterTableView...

...

</Columns>

<EditFormSettings...

<telerik:RadComboBox ID="list_Students" runat="server" SelectedValue='<%# Bind("StudentID") %>' DataSourceID="linq_Students"

DataTextField="StudentName" DataValueField="StudentId">

</telerik:RadComboBox>

...

protected void linq_Student_Selecting (object sender, LinqDataSourceSelectEventArgs e)

{

Here I want to find Key Value.

}

With ASP Grid we can obtain the same behaviour using following technique.

<asp:LinqDataSource ID="linq_Students" runat="server"

ContextTypeName="dbLibrary.StudentDataContext"

TableName="tbl_Students" OnSelecting="linq_Student_Selecting">

<asp:ControlParameter ControlID="ASPGridName" DefaultValue="0"

Name="StudentID" PropertyName="SelectedValue"

Type="Int32"/>

</SelectParameters>

</asp:LinqDataSource>

protected void linq_ContactPersons_Selecting(object sender, LinqDataSourceSelectEventArgs e)

{

Console.WriteLine(e.SelectParameters.ElementAt(0).Value);

}

RadWindow as the main control container

I think its really nice that the RadWindow can be used as a div-like control container. This works nice when there is just one or two windows on the webpage. However, I need to create about 4 "dashboards" on my webpage. With the RadWindow I need to end the content templates to place controls onto the window. With 4 windows on the page tings do nto lineup correctly. I also have to expand the template editor on all 4 windows to see what the whole page looks like.

Are there any guidlines to using the RadWindow in my scenarion or should I be using a different apporach??

Thanks in advance!

Strange behavior with RadWindowManager

Hi,

I am using RadWindowManager to open radwindows and I'm opening the window from clientside (i.e from javascript). On test, I have noticed that the rad window loads in its first call status and not get refreshing on its consecutive calls with new values when i pass the same querstring. The window should reload (actually the page load event of radwindow itself not called in the consecutive calls) so that i can show the values updated in the previous load.

To achieve this I used ReloadOnShow="true", its working but the page is get loaded 2 times, which takes double time to load the radwindow. So I tried to use ReloadOnShow="false" and PreserveClientState="false". Now the expected behavior is working. But if I refresh the page the page load is not get loaded again (ie, radwindow get loaded in its previous state). What I need to load the page with current state without loading it double time. I don’t like to use some random numbers in querystring as a parameter. Is there any better solution than this?

Please help me

Retain values for InsertMode on popup form

I am having an issue retaining the values in a popup form if the save of the underlying object is not successful. Specifically, I am using a custom ObjectDataSource and handling its Inserting event. I then attempt to create a new object, bind it's value to those found on the popup's controls, and save the object in a try/catch block.

If the save throws an exception, I set a class level variable (_errorOccurred) to true. Then, I handle the Grid's ItemUpdated event as shown below:

    
            protected void RadGrid1_ItemUpdated(object source, Telerik.Web.UI.GridUpdatedEventArgs e)  
        
            {  
        
               e.KeepInEditMode = _errorOccurred;  
        
            }

What this does is keeps the popup open, which works great. However, all of the values are lost, and the user has to re-enter all of the values.

How do I retain the values in the popup in this case?

Thanks!
