I have an application where I have an Ajax tab control (which is created at design time-- no it's not a telerik tab control) and has 35+ seperate tabs currently which are populated with a couple text boxes and a couple dropdown lists for inputting of new data.  Once I added the Prometheus Editor (also at design time) I started encountering an error. 

The error is: "Stop running this script?  A script on this page is causing Internet Explorer to run slowly.  If it continues to run, your computer may become unresponsive."  After I click "No" it loads fine, albeit the whole thing runs rather slow for an Ajax app....

Obviously this issue occurs only once I added the Editor control, and yes, there are 35 of them loaded at once.  My problem is that there could be up to 50-75 alltogether (eventually) loaded at once.  If it can't even load 35 without an error message, I cringe to think about when more are added...   Any ideas on what could be the problem? 

Perhaps disable some features of the Editor or something?

Here's how I'm adding the Editor... 

Dim

tbEOSDet As RadEditor = New RadEditor
tbEOSDet.ID = "EOSDet" & i + 1
tabcontent.controls.Add(tbEOSDet)

Thanks in advance for any help.

Is there a way of catching the client side event of "maximized" i.e. running code after a window is maximised or resized for that matter?

Thanks

I need a javascript code that gives me the total of all amounts entered in previous columns.

can any on help?

I seem to recall a setting that would force all of the details tables to populate on page load, which would then cause expanding / collapsing to happen client-side.

Can anyone assist with information or a url that describes this behavior?

Thanks,
Matt

Hello,

I've noticed that when we paste from Word sometimes <p> tags get changed to the following:

<p style="margin: 0in 0in 0pt">

Why is this happening?

Thanks,

Hi,

I have a treeveiew control inside a radcombobox.
"OnClientNodeClicking" event of treeview I am setting the textproperty of the combobox using javascript.
I am trying to fire some event so that I can access the function in my the code behind.
I have tried "OntextChanged" & "SelectedIndexChanged" of combobox but none of them was raising the event.
If i use "OnItemsRequested" event then i am getting error "Sript control RadTreeView is not a registered script control. Script control must be registered using RegisteredScriptControl() before calling RegisteredScriptDescriptors(). Parameter name scriptControl.."

I need to load other dropdowns based on the selected tree node which is inside the dropdown.

any help will be grealy appreciated.

 <telerik:RadComboBox ID="RadComboBoxCategoryLevels"
                         Width="160px"
                         Height="150px"
                         AllowCustomText="false"
                         EmptyMessage="Any Category"
                         OnItemsRequested = "RadComboBoxCategoryLevels_ItemsRequested"

                        </ItemTemplate>
                        <Items >
                            <telerik:RadComboBoxItem Text="" />
                        </Items>                     
    </telerik:RadComboBox>   

function OnclientNodeClickingHandler(sender, e)
                        {
                        //debugger;
                            var node = e.get_node();                           
                                var combo = $find("<%= RadComboBoxCategoryLevels.ClientID %>");
                                combo.set_text(node.get_text());
                                combo.hideDropDown();        
                                combo.requestItems(node.get_text(),false);  
                                
                        }

I am trying to get the SelectedValue of a RadComboBox that is populated via a webservice. However, the SelectedValue is blank when I try to get the value when I postback. How can I get the selected value server side?

Thanks,
Ron

Hi, I am trying to create something similar to the "Load on Demand" tab strip example. http://demos.telerik.com/aspnet-ajax/tabstrip/examples/applicationscenarios/loadondemand/defaultcs.aspx

Hi 
    I have a div and onmouseover of that div i need to show the menu and when use onmouseouts from that div i need to hide that menu i tried doing this with contextmenu and successfully show/hide menu but the problem is when user onmouseouts to click the menu the menu gets hidden. I need to keep showing menu onmouseout but if user goes away i need to hide.

Here is a sample code of what i am trying to achieve.

 

<div class="items1 anchorclass" rel="submenu1" onmouseover="showMenu(event)" onmouseout="hidemenu(e)" >

 

 

<asp:ImageButton ID="imgDemographics" runat="server" ImageUrl="../App_Themes/MainTheme/Images/icon_dp_d.png" /><br />

 

Demographics

</div>

 

 

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

 

 

 

 

function showMenu(e)

 

{

 

var contextMenu = $find("<%= mnuDemographic.ClientID %>");

 

 

 

if ((!e.relatedTarget) || (!$telerik.isDescendantOrSelf(contextMenu.get_element(), e.relatedTarget)))

 

{

 

 

contextMenu.showAt(e.screenX - 40, e.screenY - 120);

}

 

 

 

// $telerik.cancelRawEvent(e);

 

 

 

}

 

function hidemenu(e)

 

{

 

var contextMenu = $find("<%= mnuDemographic.ClientID %>");

 

 

 

if ((!e.relatedTarget) || (!$telerik.isDescendantOrSelf(contextMenu.get_element(), e.relatedTarget)))

 

{

 

 

contextMenu.hide();

}

}

I just need to find a dropdown that resides in ItemTemplate of MasterTableView: Colums 3 of RadGrid. I just tried following:

DropDownList

temp = ((DropDownList)RadGridMkbzHzmt.MasterTableView.FindControl("ddlHzmt"));

It throws exception "Object reference not set to an instance of an object"

How can i get over this?

Thanks in advance...
