Safari and Image resize handlers

Hello,

I am wondering if it is possible to implement image resize handlers in Safari. I came across this thread - http://www.telerik.com/community/forums/aspnet-ajax/editor/can-t-select-images-in-safari-or-chrome.aspx and it seems the answer is currently no. Please advise.

Thank you.

Opening RadWindow from the server

The RadWindow is a client-side object – its UI is created when it is first shown and this is the point when the CSS and scripts are loaded as well. This means that it should be used on the client via JavaScript, yet it turns out that it is a very common scenario that the developer wishes to initiate the RadWindow’s showing from the code-behind.

The VisibleOnPageLoad property should not be used for this purpose. It is a behavior property which will result in the RadWindow opening every time the page is post back.

Quite often the VisibleOnPageLoad property gets set to true while the intention is that the RadWindow should only show once. Doing so will result in the RadWindow reopening if a postback is initiated from another element from the page, which is rarely the desired behavior. Also, this approach will not work in case this happens in an AJAX request and the RadWindow is not included in the partial page update.

There are several ways to work around this:
1) Register a JavaScript function from the server-side and do not use the VisibleOnPageLoad property, for example:

<telerik:RadWindow runat="server" ID="RadWindow1" NavigateUrl="http://google.com/"></telerik:RadWindow>

<asp:Button ID="Button1" Text="open the RadWindow from the server" runat="server" OnClick="Button1_Click" />

C#

protected void Button1_Click(object sender, EventArgs e)

{

//business logic goes here

string script = "function f(){$find(\"" + RadWindow1.ClientID + "\").show(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);";

ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", script, true);

}

VB:

Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click

'business logic goes here

Dim script As String = "function f(){$find(""" + RadWindow1.ClientID + """).show(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);"

ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", script, True)

End Sub

2) Reset the VisibleOnPageLoad property to false with code when suitable, depending on the particular scenario

3) Set EnableViewState to false for the RadWindowManager that contains the desired RadWindows

Chrome/Safari context menus don't do anything

I'm using the most updated version of Q1 2009 and in Chrome 3 and Safari 4, when I click on an image, the resize handles don't appear and when I right click on an image, the context menu shows up, but when I click on any of the menu items, the menu disappears and nothing happens.

Selected checkboxes unselected when using a filter & search again

Hi,
I have a combobox bound to a webservice, if I enter "1-" then the following filtered results are shows "1-a" & "1-b".
"1-a" is ticked, then a search value of "2-" is entered.
"2-a" is ticked.
After closing the combobox "1-a" is no longer selected.

It appears that the combo box loses it checked items that are no longer displayed in the filtered results.
Is their any way around this?

         <telerik:RadComboBox ID="RadComboBox1" Runat="server" Width="98%"
                    CheckBoxes="True" Filter="Contains" EnableEmbeddedSkins="true" EnableLoadOnDemand="true" >
                    <WebServiceSettings Path="webservices/MainSearch.asmx" Method="Rooms" />
                </telerik:RadComboBox>

NumericTextBoxSetting - Real numbers?

How do I set a textbox that has been assigned to a NumericTextBoxSetting control to accept real numbers. ie: a number with any number of decimal places.

The DecimalDigits property allows the setting to be 0 up to 99. This is not what I need. What if my user enters a number with 600 decimal places?

Here is my code.

TextBox tbFloat = new TextBox();

string fID = ID + "Value" + i2;

tbFloat.ID = fID;

tbFloat.Attributes.Add("name", fID);

tbFloat.Text = Value;

c2.Controls.Add(tbFloat);

Telerik.Web.UI.NumericTextBoxSetting radF = new Telerik.Web.UI.NumericTextBoxSetting();

radF.EmptyMessage = "";

//radF.DecimalDigits = ? ;

radF.Type = Telerik.Web.UI.NumericType.Number;

radF.Validation.IsRequired = false;

TargetInput fi = new TargetInput();

fi.ControlID = fID;

radF.TargetControls.Add(fi);

RadInputManager1.InputSettings.Add(radF);

In the code above I have commented out the DecimalDigits line. Running this I get a textbox that accepts real numbers just fine, but always round them down to 2 decimal places! Huh?

I need one that accepts numbers of any number of decimal places.

I even tried this...

radF.DecimalDigits = -1 ;

But that of course does not work (would have been nice if it did) :)

Any clues on this one please?

Thanks

Brad
