[Solved] Render button as links

Hi,

I would like to render the remove and add buttons as links rather than buttons, is this possible?

I don't think the add button is such a problem as i can just add javascript to an anchor to call the addFileInput method. The problem I am having is with creating a remove link, I will still render a remove link per file input, but how do you track or get the index to call the deleteFileInputAt method? Can you give me an example, I can't seem to figure out how your remove button works?

I currently have:

    
            function OnClientAddedHandler(upload, eventArgs) {  
        
                        if (upload.get_controlObjectsVisibility()) {  
        
                            var row = eventArgs.get_row();  
        
                            var removeRowLink = document.createElement("a");  
        
                            removeRowLink.href = WHAT DO I PUT HERE??  
        
                            removeRowLink.title = "remove file";  
        
                            removeRowLink.innerHTML = "remove";  
        
                            row.appendChild(removeRowLink);  
        
                        }  
        
                    }

Am I going in the right direction here?

Thanks,

Jeff

HOW TO EDIT RADGRID ??

Hi,
I can edit radgrid In Forms Editing Mode, then I can update all columns but I have problem with one column. "HİZMET KODU" column like "Products" have many items so user have to select on modal products form, instead of write product name manually. I can not open radwindow on RadGrid. On the screenshot , I only open javascript modal window, but ı cant set value from this modal form to the radgrid edit form textbox. Are there any example for this situation ?

Tooltip leaves blank DIVs

I'm using ClientIDs to position my tooltips. The place where the tooltips are in the code leaves big blank areas the size of the tips (they are pretty large) on the page.

The tips do display in the right place, but I'm assuming they render wherever you place in the code and then are manually moved to their client location by JavaScript after load, thus leaving a big hole where they originally started.

Reason for using clientIDs is that my anchors are on the master page, but the page controlling the tips is a content page.

Any suggestions on how to either eliminate the big blank areas or tag a tooltip created on a content page to a target item on the master page?

FYI: Tried storing the tips in a hidden DIV, but they no longer worked. (The big blank areas were gone, though...)

Thanks,

- Brad

Event Layout - Multiple Resource Grouping

Hello,

Can the Resource/Timeline view of the RadScheduler can be extended further please? We'd like to have a Resource view where adjacent resources, attending the same event, has the event graphically shown only once as one large extended event, instead of one per resource (which is what is shown currently). The layout we are picturing has days with resources on the vertical and time on the horizontal

I believe this was broached in previous threads:
1). Horizontal layouts and time tooltip
2). "Futures" Info: RadScheduler and RadChart

Thanks very much.

radTabStrip null is null or not an object

Hello,

I'm using a radTabStrip menu, not multipage and at times, very random, I receive a "null is null or not an object" error when I click on a tab. I could successfully click the tab prior or after receiving the error but at times the error appears.

Here is some code for the javascript.

<

script type="text/javascript" language="javascript">

function SelectMyTab(sender, args)

{

//var multiPageID = sender.get_multiPageID();

//sender.set_multiPageID(null);

args.get_tab().select();

//sender.set_multiPageID(multiPageID);

}

function UnSelectMyTab(e)

{

var tabStrip = $find('<%= MainNav.ClientID%>');

//Find the element which the mouse is over

var destElement = e.relatedTarget || e.toElement;

if ($telerik.isDescendant(tabStrip.get_element(), destElement))

return;

var initialTab = tabStrip.findTabByText("<%= MyTab %>");

initialTab.unselect();

initialTab.selectParents();

}

</

script>

As you can see I removed the multipage references. I'm wondering if that has something to do with it.

Basically, I don't want multipage. I want the tab to load a new .aspx page when clicked, which is what is happening. I have onstates set, mouseover and mouseout states.

I need to remove this error and resolve the null reference.

In debug mode, when the error occurs it breaks here:

if

($telerik.isDescendant(tabStrip.get_element(), destElement))

My RadTabStrip looks like this:

<telerik:RadTabStrip ID="MainNav" runat="server" SelectedIndex="0"
                                AutoPostBack="True" Skin="MainTheme" EnableEmbeddedSkins="false"
                                OnClientMouseOver="SelectMyTab" onmouseout="UnSelectMyTab(event)"
                                ClickSelectedTab="true" UnSelectChildren="true"
                                ontabcreated="MainNav_TabCreated">
                               <Tabs>
                                   <telerik:RadTab ID="TabHome" runat="server" Text="Home" NavigateUrl="~/Default.aspx" onmouseover="changeIt(0);" onclick="setMouseOut(0);">
                                       <Tabs>
                                           <telerik:RadTab ID="Tab1" runat="server" Text="Tab 1" onmouseover="this.style.cursor='hand';" onmouseout="this.style.cursor='default';" NavigateUrl="~/Tab1.aspx" />

                                           <telerik:RadTab ID="TabSeparator1" runat="server" IsSeparator="true" Text="|" />

                                           <telerik:RadTab ID="Tab2" runat="server" Text="Tab 2" onmouseover="this.style.cursor='hand';" onmouseout="this.style.cursor='default';" NavigateUrl="~/Tab2.aspx" />
                                       </Tabs>
                                   </telerik:RadTab>

                                   <telerik:RadTab ID="TabExtended" runat="server">
                                        <Tabs>
                                            <telerik:RadTab ID="TabExtendedPH" runat="server" />
                                        </Tabs>
                                   </telerik:RadTab>

</Tabs>
</telerik:RadTabStrip>

Any help is much appreciated, thanks in advance for your time and consideration.

Binding to LinQ datasource - resulting in some appointments not showing

Hi

Iam trying to bind a RadScheduler to a Linq datasource, i got everything working but all appointments after a specific date simply dont show up.

I tried debugging and the var q below here includes information about these appointment, however they show up in none of the RadSchedluer Views.

            protected void RadScheduler1_DataBinding(object sender, EventArgs e)  
        
                    {  
        
                        FlexyNet.Data.FlexyBookLocalDataContext db = new FlexyNet.Data.FlexyBookLocalDataContext(Connections.CurrentCenterConnectionString);  
        
                        var q = from v in db.vagtPlans  
        
                                orderby v.start  
        
                                where v.start < v.slut && v.personale_db.personale_custID == fUser.CustID && v.start >= RadScheduler1.VisibleRangeStart && v.slut <= RadScheduler1.VisibleRangeEnd  
        
                                select new { v.vagt_id, v.start, v.slut, kommentar = v.kommentar };  
        
                        this.Label1.Text = q.ToString();  
        
                        this.RadScheduler1.DataKeyField = "vagt_id";  
        
                        this.RadScheduler1.DataEndField = "slut";  
        
                        this.RadScheduler1.DataStartField = "start";  
        
                        this.RadScheduler1.DataSubjectField = "kommentar";  
        
                        this.RadScheduler1.DataSource= q;  
        
                        this.RadScheduler1.Rebind();  
        
                    }

Does the RadScheduler it self only select the appointments within the visible range or do i have to do it as above to optimize speed ?

problem using popup window

Hi,

I have just spent around 3 hours trying to sort out the problem. The problem is very simple, I have a page which has got some textboxes, its a form basically. There is also a grid on the page and a button. When the button is clicked it opens another radwindow and shows some options to the user, at the end when user clicks submit, it does some processing and closes itself and reload the parent page. The problem is if I reload the parent page I lose every thing which has been entered in the textboxes etc. I have tried every example of closing and rebinding the grid but I can only make the parent page refresh which is not what I want. I am working in DNN by the way.

Also there is another problem, I am using multiview and load ascx control in multiview according to some session variable. The problem I am facing is that multiview loads the ascx control twice on the first load which ends up duplicating the databind with treeview I have on the ascx control. Can you please help with this as well.

Please write the full code in your answer..

Thanks
Atiq

Alarm-Clock style input?

I'd like to have an "alarm clock" style input. I don't like the RadTimePicker all that much. Basically if the RadNumericInput ShowSpinControls=true allowed me to say 00..09, 10, 11..59 I would be completely happy.

Anyone know how to get the RadNumericInput to have leading 0s for < 10?

Alternatively, the asp:listbox is what I need (00:00, 00:30, ... 23:30) which looks like a spinner, but the Telerik list control doesn't do that either, as I recall.

Thanks,
Tim
