AllowdFileExtensions ignore when RadAsyncUpload moved in DOM

Hi,

I have a situation where I need to move a RadAsyncUpload control in the DOM. After I move it the AllowedFileExtensions seems to be reset to allow all extensions. I have not been able to work out how to set the AllowedFileExtensions via javascript.

Here is the problem isolated in a simple example. Initially only jpg and wmv files can be selected. But once I click the bt_MoveDiv button and move the control in the DOM, all file types can be selected.

<body>

<form id="form1" runat="server">

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

function buttonClick() {

var container = document.getElementById('container');

var ph = document.getElementById('holder');

ph.appendChild(container);

}

</script>

<div>

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<div id="container">

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" AllowedFileExtensions="jpg,wmv">

</telerik:RadAsyncUpload>

<telerik:RadProgressArea ID="RadProgressArea1" runat="server">

</telerik:RadProgressArea>

<asp:Button ID="bt_Submit" runat="server" Text="Submit" onclick="bt_Submit_Click" />

</div>

<div id="holder">

</div>

<asp:Button ID="bt_MoveDiv" runat="server" Text="Move div" OnClientClick="buttonClick();return false;" />

</div>

</form>

</body>

I had similar problems some time ago with RadEditor being moved in the DOM. This problem was fixed with the onParentNodeChanged() function. Is there something similar I can do for RadAsyncUpload?

Thanks
Andrew

Radbutton Requires two clicks to open RadWindow

Hi, I have a RadButton that is supposed to open a radwindow when the "OnClientClicked" is fired. However, the first time this gets fired, nothing happens. The second time I click on the button...the radwindow opens up. Am I missing some code? I am basing this on your demo: http://demos.telerik.com/aspnet-ajax/button/examples/slideshow/defaultcs.aspx.

Here is the code that I have:

<telerik:RadCodeBlock ID="rcb1" runat="server">

<script type="text/javascript">

function ShowInsertForm() {

var combo = $find("<%= RadComboBox1.ClientID %>");

var comboItem = combo.get_selectedItem();

if (!comboItem) {

window.radopen("AddComment.aspx", "UserListDialog");

}

else {

var string = comboItem.get_text();

window.radopen("AddComment.aspx?ID=" + comboItem.get_value(), "UserListDialog");

}

return false;

}

</script>

</telerik:RadCodeBlock>

<telerik:RadButton ID="AddComment" runat="server"

AutoPostBack="false" Text="Add Comment" CommandName="Right" OnClientClicked="ShowInsertForm">

</telerik:RadButton>

<telerik:RadButton runat="server" ID="btnUpdate" Skin="WebBlue" Text="Update Recipient"></telerik:RadButton>

</div>

</telerik:RadAjaxPanel>

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true" Skin="WebBlue">

<Windows>

<telerik:RadWindow ID="UserListDialog" runat="server" Title="Add Comment" Width="755px" Height="460px"

ReloadOnShow="true" ShowContentDuringLoad="false" Modal="true" />

</Windows>

</telerik:RadWindowManager>

I can use a plain old button, and it fires off without a second click, but I would really like to use the radbutton since that will keep my styling the same.

Thanks!

Multiselection dropdown, Default Text

Hi,

I'm displaying a Combobox with multiple item selection by means of a checkbox. Does not allow custom text. The problem is that the default text displays always the first item. Is there any way to display the default text as blank or a custom text (by not setting the 'Allow Custom Text' property to true?)

Thanks.
