[Solved] OnCommand not firing with CommandItemTemplate

I had a grid setup to display some data. When an insert occurred, I wanted to display a message so I subscribed to the OnCommand client event. This worked well and was fired when the insert command item was clicked.

I needed to customise the command item so set up a CommandItemTemplate as follows

    
                        <CommandItemTemplate> 
        
                            <table width="100%" style="margin: 5px">  
        
                                <td align="left">  
        
                                    <span class="GridTitle">Accounts</span> 
        
                                </td> 
        
                                <td align="right">  
        
                                    <asp:LinkButton runat="server" class="GridCommandButtonText" CommandName="InitInsert">  
        
                                        <img style="border:0px;vertical-align:middle;" alt="Insert" src='<%= ToAbsoluteURL("~/Images/Add_24.png") %>' />&nbsp;&nbsp;Add new account  
        
                                    </asp:LinkButton>&nbsp;&nbsp;&nbsp;&nbsp;  
        
                                    <asp:LinkButton runat="server" class="GridCommandButtonText" CommandName="RebindGrid">  
        
                                        <img style="border:0px;vertical-align:middle;" alt="Refresh" src='<%= ToAbsoluteURL("~/Images/Refresh_24.png") %>' />&nbsp;&nbsp;Refresh account list  
        
                                    </asp:LinkButton>&nbsp;&nbsp;&nbsp;  
        
                                </td> 
        
                            </table> 
        
                        </CommandItemTemplate>

This displayed as I wanted it to, however the insert and refresh buttons don't fire the client event, they only fire the server event. Is there a way that these can conform to the standard process and call the OnCommand event or is this a bug.

I am running the the latest version of RadControls.

Thanks

Problem in Hierarchical Grid Export to excel

Hi there,
I m using telerik 2008.02.0826.20 version. While exporting my RadGrid to Excel Cannot find a cell bound to column name 'InvoiceId'

    
            <MasterTableView Width="100%" Name="Master" HierarchyLoadMode="ServerBind" DataKeyNames="InvoiceId" 
        
            HorizontalAlign="NotSet" CommandItemDisplay="Top"> 
        
            <DetailTables> 
        
            <telerik:GridTableView Name="Detail" BackColor="White" AllowNaturalSort="true" runat="server" 
        
            DataKeyNames="invoiceidfkid" Width="100%"> 
        
            <ParentTableRelation> 
        
            <telerik:GridRelationFields MasterKeyField="InvoiceId" DetailKeyField="invoiceidfkid"> 
        
            </telerik:GridRelationFields>

rgInvoice.MasterTableView.HierarchyDefaultExpanded = true;

Scheduler without dates

Hi

What I've been tasked to do is develop a method of populating the scheduler for upto a year with repeating tasks in either 1,2,3 or 4 week cycles.

Is it posible to give users a generic schedule view in weeks ie week 1, Week 2, Week 3 Week 4 that they can load with schedule data but not tied to dates, and when they submit I can then fill the scheule with these repeating items?, the start date will be one I choose.

Multiple Item Selection "Shift" Key

I was experimenting with the listbox control and noticed that it does not support the shift key for multiple selection. I think this is going to be a feature the users of our website are going to ask for. They are used to selecting one item then clicking an item two or three items further down in the list while holding the shift key down and having all of the items between the first and last item selected.

Also, is there a way to prevent the text from being selected while clicking and dragging over the top of the list items? Highlighting the row is fine, but having the text within the highlighted row also be selectable makes using the control a little confusing.

[Solved] Javascript showPopup() only flashes visible

Hi,
I have a asp:button that calls the shopPopup() method of the datetimepicker as below.
Although this visibly works, the popup is only momentarily displayed before becoming hidden. This is so fast that it looks like a flicker. I presume this is something to do with the postback from the page when the button is pressed resetting the datetimepicker but I am unsure of how to fix it.
If anyone can help it would be very welcome.

    
            <script type="text/javascript">    
        
            function ShowPopup()    
        
            {  
        
                var datetimepicker = $find("<%= txtcalMeetingDate.ClientID %>");    
        
                datetimepicker.showPopup();  // Show Calendar popup       
        
            }    
        
            </script>

<asp:button runat = "server" name= "View Calendar" id = "CalendarPopup1" visible = "false" />

and in code-behind:

CalendarPopup1.Attributes.Add(

"onClick", "ShowPopup();");

how to set value in slider

Hi,

i am using RadSlider and RadTooltip on my page. I am able to show a slider and save values in database. but in edit mode, when i have the value in database which user selected, i am not able to show it through slider.

In other words, i want to show db value in slider and let the user decide whether the old value is correct or if user wants to change this value, he should be able to do this.

i get following javascript error..

"Radtooltip" is undefined.

I wanted to know which property would be best to show already selected value in slider and how we can use that?

Any help is appreciated.

Thanks in advance,

disable backspace on page navigation

Hi, everybody.

I just want to share a solution I found to one of my problem. I wanted to disable the backspace funtionality of returning to the previous page. This worked fine for me and I hope it helps anyone:

javascript code:

var

teclatextbox= false;

function

TeclaTextbox(presionada)

{

teclatextbox= presionada;

}

function

BodyKeyDown(e)

{

var key;

if (window.event)//IE

key= window.

event.keyCode;

else//Firefox

key= e.which;

if(!e) var e = window.event;//take event

if (key == 8 && !teclatextbox)//BACKSPACE and it is not inside a textbox

{//stop the default behavior

e.cancelBubble =

true;

e.returnValue =

false;

if (e.stopPropagation)

{

e.stopPropagation();

e.preventDefault();

}

return false;

}

return true;

}

textbox events to permit backspace only inside the textboxes:

<

asp:TextBox ID="txbComentarios" runat="server" onkeydown="javascript:TeclaTextbox(true);" onkeyup="javascript:TeclaTextbox(false);" onblur="javascript:TeclaTextbox(false);"></asp:TextBox>

Regards,
Daniel.
