ajaxRequestWithTarget doing full postback

My problem is my call to ajaxRequestWithTarget is doing a repost when I expect an ajax update.

I have a master page containing RadAjaxManager, and a content page containing two user controls, uc1 and uc2.

uc1 has a ajax-enabled asp:Button and a text box inside an asp:Panel. Clicking on uc1.Button1 does the right thing, an ajax update without a full page refresh. My Page_Load:

                    protected void Page_Load(object sender, EventArgs e)         
            {         
              RadAjaxManager radAjaxManager = RadAjaxManager.GetCurrent(Page);         
              radAjaxManager.AjaxSettings.AddAjaxSetting(uc1.FindControl("Button1"),  uc1.FindControl("Panel1"), null);         
            }         

I have a list box in uc2. When an item in uc2.List1 is clicked, I want to simulate clicking uc1.Button1. My javascript code looks something like:

                    var ajaxManager = $find('<%= RadAjaxManager.GetCurrent(Page).ClientID %>');         
            var buttonID = '<%= GetUc1Control("Button1").UniqueID %>';         
            ajaxManager.ajaxRequestWithTarget(buttonID, '');         

The call to ajaxRequestWithTarget is correctly updating the content of uc1, but it is causing a refresh of the entire page. How do I fix this problem?

Javascript error on Mouseover a disabled radcombobox in a usercontrol, which act as an edit template of radgrid

Hi,

I am getting javacript errors while hovering over disabled radcomboboxes in a user control. I am using this usercontrol to display when I load radgrid edit template.
I am enabling and disabling combos based on values in edited row in pageload of usercontrol.ascx.cs and on moving the mouse over the disabled combos, I get error "Value must be a DOM element"

I did searched in telerik forums and located a post discussing similar issue and following solution was suggested there,

    
            <script type="text/javascript" language="Javascript">  
        
                    var oldDomEvent = Sys.UI.DomEvent;  
        
                    Sys.UI.DomEvent = function(rawEvent) {  
        
                        if (rawEvent.srcElement && typeof (rawEvent.srcElement.getClientRects) == "undefined") return;  
        
                        var evt = new oldDomEvent(rawEvent); for (var o in evt) this[o] = evt[o];  
        
                    }  
        
                    for (var o in oldDomEvent) Sys.UI.DomEvent[o] = oldDomEvent[o];     
        
                </script>

This solution do prevent error on mouse hover but throws other javascript errors ( error with browser event handlers or similar) when I perform update or close usercontrol or click on edit command of another row.
Therefore , I need a better and stable solution than the script above to fix my error when I hover over disabled radcomboboxes.

Thanks

Filtering ItemTemplate (not column)

Hi there, I have a RadGrid with an Item tempalte

<telerik:RadGrid.... >
<ItemTemplate>
.....
</ItemTemplate>
</telerik:RadGrid>

I'd like to filter the items in my item template, based on a value selected in a treeview. In this case the treeview contains, property types - bungalow, house etc, and the itemtemplate contains a table displaying the various information on a property.

Is this possible ?

In the selectednodechanged event i'm attempting to apply the filtering there.
MyGrid.MasterTableView.FilterExpression = ...

But it can't find the field i'm specifying. Do i have to use a column bound to this datafield in order to filter ?

RadEditor in Opera doesn't preserve new line>

Hello,

I have issue with RadEditor in Opera browser. When I press 'enter' button in Design mode and then switch to HTML and again back to Design, new line is lost. The same is when I do the above and press e.g. Save button (RadEditor inside FormView bound to some db field), new line is lost.

This can be easily reproduced here:

http://demos.telerik.com/aspnet-ajax/editor/examples/default/defaultcs.aspx

press enter with cursor placed after 'tons of features:'

switch to HTML and back to design

I tried it with Opera 10.53 and RadControls Q1 2010

I also tried to switch NewLineBr=true/false but no success.

Is there any workaround for this?

Thanks,

Robert

[RadCalendar] Automatic week selection instead of the day selection

Hello,

I use a RadCalendar. My problem is the following : when the user select a day, I want to deselect all the selected days and select all the week.
So, I use the following parameters :

UseColumnHeadersAsSelectors

="false" EnableViewSelector="false" UseRowHeadersAsSelectors="true"

For the unselection, it's not a problem, I use the methods unselectedDates and get_selectedDates (for the events OnDateClickand OnRowHeaderClick).

But I don't think a easy to select all the week :
I have 2 ideas to do that :
- Obtains the row (args.get_renderDay().DayRow) and call the method used for a row header click, but I don't see how to call it.
- create a new Date javascript object based on the triplet returned by args.get_renderDay().get_date() and, using the getDay method, manually compute the day for the monday, the tuesday... But I think this way is not the best to do that.
What's the good solution ?

Thank you in advance,

Christophe.

RadDatePicker highlighting multiple dates when activated in succession

I have noticed a problem with the date picker where it highlights extra dates sporadically between activation and date selection. It's almost like the calendar hover style gets stuck on sometimes.

You should be able to reproduce the problem even on the Telerik demo for this control at the following link:

http://demos.telerik.com/aspnet-ajax/calendar/examples/datepicker/custompopup/defaultcs.aspx

Just click the button and select a date multiple times. I'm not sure precisely what is triggering it because it doesn't happen all the time. I've attached an image with the problem.

Thanks,
Dave

RadWindow titlebar is not visible when displayed above <embed> tag

Hi,

I am having a page which displays user agreements(pdf format). I use 'embed' tag for this.
<embed id="embAgreement" runat="server" Width="625" Height="400"></embed>

I need to display an alert window above this based on some conditions. But my window tilebar and border is not visible when it is displayed above this embed tag object. The model behaviour is also not working properly.

I tried even specifying VisibleTitlebar="true" property and Overlay="true" explicitly. But it also didnt help me out.

I am using Telerik version Q2 2009. But in other places the rad window behaves as expected.

If anybody knows how to solve this issue please help me.

Thanks in advance
