Questions on UI for ASP.NET AJAX Forum

55 views

Hello,

I'm attempting to click a link Button from within my asp.net application page which is part of a master page. Upon clicking the link, I want a radWindow to pop-up, modal. This all works. But when I attempt to close the radWindow, it will refresh the parent page, which causes me to lose any changes made to the screen before I popped up the dialog.

I've followed the demo at: http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=window

I just can't seem to get this working. I basically want to call the dialog, and upon exiting it, update a widget on the form that called the radWindow.
Question:
1. Should I pop up the radWindow from javascript or from code-behind?

Any help would be appriciecated

Ajax Manager doesn't work with button in RadWindow

I've configured an ajax manager so that a button inside a radwindow would update the radwindow in which it resides. Instead of working properly the button caused a full pledged postback. Any help would be much appreciated.

Possible to trap the cursor position w/ OnBlur event and get_caretPosition()?

I'm trying to get the last position of the cursor when the user clicks outside of the RadTextbox, but I'm not quite sure it's working how I was hoping. I added an OnBlur client event in the mark-up:

    
            <telerik:RadTextBox ID="rtxtTemplateContent" Runat="server" Height="100px" TextMode="MultiLine" Width="250px">  
        
                <ClientEvents OnBlur="setCursorPosition" /> 
        
            </telerik:RadTextBox>

Next I have my JavaScript:

    
            function setCursorPosition(sender) {  
        
                var cursorPosition = sender.get_caretPosition()  
        
                document.getElementById("hdnCursorPosition").value = cursorPosition;  
        
            }

My goal is to trap the last cursor position and save it in a hidden field on the page for use w/ drag'n'drop functionality from a RadListBox to the RadTextBox. It seems like it's working correctly except the numbers come out really random. For instance, I put 10 characters in the textbox and then put the cursor in the middle and clicked out of the textbox, but the number returned by get_caretPosition() was 80? Doesn't make sense to me... any ideas or suggestions? Is what I'm doing possible or has the cursor position been lost by the time the OnBlur event is fired?

Cannot call method 'selectDates' of null

I have a page that loads dates into a hidden field.

I'm using Javascript to parse and hilight the dates. Using an onClick function works perfectly, but I need this to load when the document is ready. Every time I try this I get "Cannot call method 'selectDates' of null" - which implies that the calendar is not yet loaded. I tried using the onLoad and onInit events - same error.

Here's the code:

<script type="text/javascript">

//-------------------------------------------------------------------------------

function renderDates() {

//---------------------------------------

var calendar = $find("<%= cal_Calendar.ClientID %>");

var hf_Dates = document.getElementById("<%= hf_SelectedDates.ClientID %>"); //hidden field

var DateStrings = hf_Dates.value.split('|');

//---------------------------------------

var Dates = new Array(DateStrings.length);

for (var i = 0; i < DateStrings.length; i++) {

var dt = convertToTriplet(DateStrings[i]); //see function below...

Dates[i] = dt;

}

//---------------------------------------

calendar.selectDates(Dates); //ERROR OCCURRS HERE!

}

//-------------------------------------------------------------------------------

function convertToTriplet(dateString) {

var dp = dateString.split('/');

var array = new Array(dp[2], dp[0], dp[1]);

return array;

}

//-------------------------------------------------------------------------------

</script>

If I call this using jQuery, I still get the error - what the hell is going on?

can get custom properties of ineheritated radcombobox in javascript

Hi,

Sorry, the title should say "Cannot" instead of "Can" :)

I am using a custom combobox which inheritates from the RadComboBox. I have added some public properties which are

[PersistenceMode(PersistenceMode.Attribute)]

I need to access these custom properties from a javascript function called from the OnClientBlur client side event. Unfortunately they are not acessible. I must be missing something very obvious but I am stuck as some code in this function must only be performed depending on the values of these properties. How can I achieve that?

Thank you for your help!
