Hi, I'm having issues executing a RadAjaxManager OnAjaxRequest.  I am following the "Window / Edit dialog for Radgrid" Window option demo in order to rebind a RadListView when data is added within the Rad pop up Window.  The difference between my layout and the example is I am using a master page architecture.  So I have a master page then and aspx page within the content and a user control within that aspx page.  My Rad Window is within the user control.  Since I have my RadAjaxManager within the master page I am unable to execute a command within my user control to rebind my RadListView within that user control.  How would I do this?


----- I am trying to execute the refreshGrid function below called from my RadWindow to rebind a radlist view.  My problem is my radajaxmanager is within a master page and my radlistview is in a user control.

        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RadListView1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>

       function refreshGrid(arg)
       {
           if (!arg)
           {
               $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");
           }
        }

        protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
        {
            if (e.Argument == "Rebind")
            {
                RadListView1.Rebind();

        }

Hi,

I need to make the selection of the RadSplitButton when RadDropDownButtonElement is selected. For make this, I'm changing Style Parameter of the different buttons and when another button is Selected I have to restore Original Values.

For make this, I've made one event:

public void SelectedChanged(object sender,EventArgs e){


            RadSplitButtonElement SendingSplitButton = sender as RadSplitButtonElement;
            RadSplitButtonElement[] ButtonArray = { orbit, rotate, horizontalMove, verticalMove, zoom };

 for (int i = 0; i < 5; i++)
            {
                ButtonArray[i].ActionButton.ButtonFillElement.BackColor = System.Drawing.Color.transparent;  <- Setting the original Values
                ButtonArray[i].ActionButton.ButtonFillElement.BackColor2 = System.Drawing.Color.transparent;
                ButtonArray[i].ActionButton.ButtonFillElement.BackColor3 = System.Drawing.Color.transparent;
                ButtonArray[i].ActionButton.ButtonFillElement.BackColor4 = System.Drawing.Color.transparent;              

            }
           /*Setting Selected Values...*/
            SendingSplitButton.ActionButton.ButtonFillElement.BackColor = System.Drawing.Color.FromArgb(255,255,115,0);
            SendingSplitButton.ActionButton.ButtonFillElement.BackColor2 = System.Drawing.Color.FromArgb(255,255, 115, 0);
            SendingSplitButton.ActionButton.ButtonFillElement.BackColor3 = System.Drawing.Color.FromArgb(255,255, 115, 0);
            SendingSplitButton.ActionButton.ButtonFillElement.BackColor4 = System.Drawing.Color.FromArgb(255,255, 115, 0);
            SendingSplitButton.ActionButton.ButtonFillElement.GradientPercentage = 0.62f;
            SendingSplitButton.ActionButton.ButtonFillElement.GradientPercentage = 0.71f;
}

I have already tried changing the State of the Objects in this mode:

SendingSplitButton.OnMouseOver = true or with SendingSplitButton.OnMouseDown= true but it doesn't work. I don't understand very well if it is possible or not managing only a single state of the object through the code and how the Style Managing - by code - and Xml is merged.

Thank you very Much,

Hi, i want to disable postback or callback on RadTreeView when the user click a node, i also want with javascript function get the NavigateUrl and assign it to a iframe, all in client side without server side.

Hello,
I am using RAD GRID and one column is linkable to other page. So when I hit on the link of one of the populated records of Rad Grid then it goes to next page. The problem is when I go back using BACK button of browser then Grid's data lost. I can put the data in the session like datatable and populate it again but there are other 150 controls on the same page too from which I am populating grid and some are Grid Dropdowns.
So In short I need to maintain that Controls along with RadGrid when I click on back button of browser.
Rather than storing everything in Session or viewstate, Is there any other way to do it.
Please response ASAP.
Thanks,
Deepa

Hi,

I wish to implement the following:
Present a RadToolTip within a RadWindow that has a RadAjaxManager to present nofications to the user on several ocassions (e.g. input was not properly given). So I put it in RadAJAx setting along with an imageButton I wish to present it accordingly. Also size of the RadWindow is not automatically fitting when using RadAjaxManager (if I drop the use of RadAjaxManager, it works fine).

That's the code, for example:
1. RadWindow Code - rtt is the RadToolTip I wish to show on occassions:


and the code behind - whenever I wish to present the RTT I use:


2. the code that opens the RadWindow (from an aspx page) and get necessary arguments from the RadWindow:

3. codebehind example for use - CloseAndRebind is a javascript function within RadWindow (this function it works peorperly):


The results are:
1. When I delete RadAjaxManager use - everything works fine.
2. When I put it RadAjaxManager back in, the ToolTip is not presented
3. Also, when I use RadAjaxManager the size of the RadWindow is not automatically fitting the form, when the form changes its size
4. Without using RadAjaxManager, the RadWindow's size is modified automaticcaly to the contents of the form (as it should be)

I wish to use RadAjaxManager and get the following results:
1. The RadWindow's size is modified automatically to the contents of the form.
2. The RadToolTip must be showed.
3. The ToolTip must be given a CSS style (this one is not ralated to RagAjaxManager, but I'm not able to use a CSS in rtt within a RadWindow - in other forms, which are not RadWindow, it works.)

Most important - The RadWindow size must fit automatically to form size (The form's size is modified since the RadGrid changes its size almost every postback).

Thanks in advance.

Best regards,
Avi Akessoul

Hi,
 I have to add features of Track Changes as given in MS word.IS anyone have used such features in RADEditor.

Regards
Rashid

After looking around in some other threads and trying myself I am unable to rename or delete the top most node in the treeview. I have read that this is disabled but is there a way to enable this feature? I am currently using a custom DBContentProvidor so allowing the end user to rename the root nodes should be possible.

Hi. I'm using RadAjaxManager and it's client events OnRequestStart/End to do some client side stuff. Well recently a need came up to do something before each start and end events across all pages of the app. I thought it would be relatively simple by replacing OnRequestStart function via javascript's ".apply" method (you can see it in included code below). However, I ran into an issue where what I wanted to do only happens on second and all subsequent requests, BUT not on the first request. I even thought of using PageRequestManager's request begin/end events, but those happen after the AjaxManager events and I need to do things before those.  Below is timing of what happens, via firebug's console.log.

on ajax request start
begin request via PageRequestmanager
POST
end request via PageRequestmanager
on ajax request end

modified ajax start
on ajax request start
begin request via PageRequestmanager
POST
end request via PageRequestmanager
on ajax request end
modified ajax end

Again, second set is what I want to have happen, however Telerik must be doing something that's preventing me to replace RadAjaxManager OnRequestStart/End functions, like below, again it works just fine second time AjaxManager is triggered:
           var start = OnAjaxManagerRequestStart;
           OnAjaxManagerRequestStart = function() {
               console.log('modified ajax start');
               //doing something here
               start.apply(this, arguments);
           };

Code is below, any ideas?

I have a page that is similar to a portal with multiple widgets on the page. Each widget has a "container" with the title of the widget. All the widgets are implemented as user controls. Within the container is the actual content of the widget.

Since I have a large number of these on the page, the page takes a while to render. For better user experience, I would like to have the titles of the widgets loaded first and then individual widgets show up as and when they load.

Can I use any of the telerik controls for this behavior?

The above code demonstrates the issue I am having (for the WebService.asmx, use any code that sometimes returns no items).

When no items are returned, there is still an ugly, 2px line showing. This is because even if there are no items, the <ul> and other surrounding divs still render. If the <ul> tag has a border, as it does in many of the skins, then the ul's border still shows even when there are no items.

Unfortunately it is very difficult to fix this problem. CSS does not have the ability to hide the <ul> if it has no child <li> elements.

I have tried going down the javascript route, using OnClientItemsRequested or OnClientDropDownOpening, but have faced too many headaches.

Does anyone know of a good solution?
