Questions on UI for ASP.NET AJAX Forum

Hi there,

We presently have a number of RadChart controls in a single page that we are looking to ToolTipify.
After some study, we learnt that this is possible if we were to add a RadToolTipMgr directly underneath the RadChart in question and set the manager's ToolTipZoneID value as the ClientID of the containing div.

However there are two things that we need clarification on, these are:

1) If we move the RadToolTipManager to the top of the page, it stops working as intended, is this true or are we doing something wrong?
2) Is there any way to have one RadToolTipManager that targets a number of ToolTipZoneIDs? we have approximately 8 RadChart's that we would like to ToolTipify, which based on our current knowledge for this control would require 8 RadToolTipManagers.

Hope you can help

Regards

A.

Over-riding relative paths

Hi

We have set our config file to strip out absolutepaths so that they are all changed to relative ones. This is correct and how we want it, however occassionally we do need to insert an absolute path into the RadEditor and I would like to know if there is a way to do this that prevents the overall config from converting it to a relative path?

Thanks

Using RadEditor to post messages with images/media /documents without uploading them to the server befor clicking the submit button

Hello,

I need to use the raeditor control in order to post a messages within forum. As you know some of the forum messages could contain images, documents, media or other components.
I know how to use the ImageManger, DocumentManger ... dialogs in order to upload that components. But the problem is that these components must be uploaded to the server even before clicking the submit button in order to insert them the content area.

How can I post the forum messages with the diffrent components I mentioned above without uploading to the server until I click the submit button?

Regards,
Bader

Populate RadNumeric Box in RadGrid via RadComboBox Selection

Hi

I have a RadComboBox (EnableLoadOnDemand is True) and 3 numeric boxes in Edit Template in a RadGrid.

What I am trying to do is when a user selects a option in the RadComboBox then it populates the Textboxes via its attributes.

I have the following javascript which I have used to do this previously but not in a Grid

                function rcb_Changed(sender, args) {
                    //copy port long/lat to input boxes
                    var item = args.get_item();
                    var Longitude = item.get_attributes().getAttribute("Longitude");
                    var Latitude = item.get_attributes().getAttribute("Latitude");

                     var rtxtLongDegree = $find("<%=rtxtLongDegree.ClientID %>");
                    rtxtLongDegree.set_value(Longitude_Deg);

                }
<telerik:RadComboBox ID="rcbPortList" runat="server" AllowCustomText="false" DropDownWidth="590px"
   EmptyMessage=" - Select a port - " EnableLoadOnDemand="True" Height="150px" HighlightTemplatedItems="true"
   MarkFirstMatch="True" Width="170px" OnClientSelectedIndexChanged="rcb_Changed"
   ShowMoreResultsBox="True" EnableVirtualScrolling="True">

I have tried chaging "<%=rtxtLongDegree.ClientID %>" to the name of the Textbox in the Grid Edit Template but I get an error saying it cannot find the control.

How do I do this is so when I change the ComboxBox in the Grid it populates the textboxes,,... Using Javascript.

Thanks in advance

Apparent limit on recurring event in scheduler

We have encountered a problem with recurring scheduling entries. I am not sure if this is caused by a default value or is a limitation that cannot be overcome.
When entering repeating scheduler entries without an end date, it appears that there is a hard stop after 3000 occurrences. After the 3000th entry the next run date is basically empty and no further entries are in the scheduler. Our clients have events that are recurring on an hourly basis, which would limit the availability of the recurring entry to only 125 days. Is there a default setting I am missing?

Ajax problem when using Ajaxmanager and RadAjaxpanel

Hi,

I am using a RadPanel bar with three panel items. I want to load the controls dynamically in each panel item depends on the panel item expanded. I have using the client side event "onclientitemexpand" to generate the postback. In the client side function first i have used the __doPostBack function to initiate the postback. When I am using __doPostBack the page will be refreshed so i move to the following ajaxrequest function "$find("<%=ajaxmanager1.ClientID%>").ajaxRequest("PanelItem");. But nothing will happened that is the page is not postbacked. I attach the code below.

C#

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using Telerik.Web.UI;

using System.Web.UI.WebControls;

public partial class RadPanelDemo : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

CustomContentTemplate1 template1= new CustomContentTemplate1();

CustomContentTemplate2 template2 = new CustomContentTemplate2();

if (IsPostBack)

{

lblpost.Text = "OnPostBack";

}

foreach (RadPanelItem item in RadPanelBar1.Items)

{

if (IsPostBack)

{

Response.Write("post");

item.ContentTemplate = new CustomContentTemplate2();

template2.InstantiateIn(item);

item.DataBind();

}

else

{

Response.Write("load");

item.ContentTemplate = new CustomContentTemplate1();

template1.InstantiateIn(item);

item.DataBind();

}

ajaxmanager1.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(ajaxmanager1_AjaxRequest);

}

void ajaxmanager1_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

Response.Write(e.Argument);

}

class CustomContentTemplate1 : ITemplate

{

public void InstantiateIn(Control container)

{

Label label1 = new Label();

label1.Font.Bold = true;

label1.DataBinding += new EventHandler(label1_DataBinding);

container.Controls.Add(label1);

}

private void label1_DataBinding(object sender, EventArgs e)

{

Label target = (Label)sender;

RadPanelItem item = (RadPanelItem)target.BindingContainer;

target.Text ="load";

//Alternative way:

//string itemText = (string)DataBinder.Eval(item, "Value"); target.Text = itemText;

}

class CustomContentTemplate2 : ITemplate

{

public void InstantiateIn(Control container)

{

Label label1 = new Label();

label1.Font.Bold = true;

label1.DataBinding += new EventHandler(label1_DataBinding);

container.Controls.Add(label1);

}

private void label1_DataBinding(object sender, EventArgs e)

{

Label target = (Label)sender;

RadPanelItem item = (RadPanelItem)target.BindingContainer;

target.Text = "post";

//Alternative way:

//string itemText = (string)DataBinder.Eval(item, "Value"); target.Text = itemText;

}

class CustomContentTemplate3 : ITemplate

{

public void InstantiateIn(Control container)

{

Label label1 = new Label();

label1.Font.Bold = true;

label1.DataBinding += new EventHandler(label1_DataBinding);

container.Controls.Add(label1);

}

private void label1_DataBinding(object sender, EventArgs e)

{

Label target = (Label)sender;

RadPanelItem item = (RadPanelItem)target.BindingContainer;

target.Text = item.Value;

//Alternative way:

//string itemText = (string)DataBinder.Eval(item, "Value"); target.Text = itemText;

}

ReadOnly RadNumericTextBox not firing OnFocus()

Hello,

When I set ReadOnly=true on a RadNumericTextBox via markup, the client event OnFocus() does not fire.

<telerik:RadNumericTextBox CssClass="FarmSerialNumber" ID="rntbAcreageFarmSerialNumber"

runat="server" Width="40px" Value='<%# DoubleFromDb(Eval("FarmSerialNumber"), true) %>'

ReadOnly='<%# DoubleFromDb(Eval("FarmSerialNumber"), true) != null %>' MinValue="1">

<NumberFormat DecimalDigits="0" GroupSeparator="" />

<IncrementSettings InterceptMouseWheel="false" />

<ReadOnlyStyle ForeColor="Gray"></ReadOnlyStyle>

<ClientEvents OnValueChanged="radNumericTextBox_ClientValueChanged" OnFocus="acreageControl_ClientFocus" />

</telerik:RadNumericTextBox>

The documentation does not mention that this doesn't fire when it is readonly.
http://www.telerik.com/help/aspnet-ajax/input-client-side-onfocus.html

To ensure that this is not a problem with the <input> element, I added this and it works fine.

<input type="text" onfocus="alert('Yup. Works')" readonly="readonly" />

Is this a bug or by design?

Thanks!
Thad
