Hi!

We are trying to validate controls in a form template. The javascript code shown below fires, but how do I reference the controls in the template in code behind? We want to make sure the text box and combo box has a value.

Thanks for your help!

<editformsettings editformtype="Template">

<FormTemplate>

<telerik:RadTextBox ID="inputBoxIdentifier" runat="server" CssClass="inputBox" Style="top: 0px; left: 0px" Skin="Windows7" SelectionOnFocus="SelectAll" EnableViewState="true">

<InvalidStyle CssClass="inputBoxInvalid" />

<telerik:RadComboBox ID="comboBoxIdentifier" runat="server" CssClass="radComboBox" OnDataBound="radComboBox_DataBound"

OnSelectedIndexChanged="radComboBox_SelectedIndexChanged" Filter="Contains" Skin="Windows7"

EnableLoadOnDemand="true" EnableViewState="true" />

<telerik:RadButton ID="radButtonInsertUpdate" runat="server" OnClientClicking="performInsertOrUpdate"

Text='<%# (Container is GridEditFormInsertItem) ? "Insert" : "Update" %>' CommandName='<%# (Container is GridEditFormInsertItem) ? "PerformInsert" : "Update" %>' CssClass="esbutton" />

<telerik:RadButton ID="radButtonCancelInsertUpdate" runat="server" OnClientClicking="cancelInsertOrUpdate"

Text="Cancel" CausesValidation="false" CommandName="Cancel" CssClass="esbutton" />

</FormTemplate>

</editformsettings>

function performInsertOrUpdate(sender, args) {

var error = 0;

var controlRef = $find("<%= radGridClientIdentifiers.ClientID %>").get_masterTableView();

// any items being inserted?

var insertedItem = controlRef.get_insertItem();

if (insertedItem != null) {

}

var editedItemsArray = controlRef.get_editItems();

if (editedItemsArray.length > 0) {

}

if (error == 1)

return false;

return true;

}

Upload on Ajax ModalPopupExtender in IE8 Compatibility Mode

I have an internal site that runs under IE8 with Intranet settings, and thus runs in Compatibilty mode. I do not have the access or permission to force the site into regular mode using headers or IIS - in other words, it must run in Compatibility mode.

On the site, I have an Upload control that resides on an asp:Panel, that is associated with the ajax control toolkit's ModalPopupExtender. The Upload control is set to use 3 input boxes.

When the user opens the modal, and I have enablefileinputskinning="false", the input boxes have an inline style assigned that sets the width as 15px (see attached image fileskinfalse.png). If I set the enablefileinputskinning="true", the input boxes are the correct size, but are transparent through the modal down to the page, and the user can't interact with the elements (see image fileskintrue.png).

Any thoughts or ideas on how to get the input boxes to show correctly?

RadWindow NavigateUrl autoSize different webserver

Hello

I believe the title says it all.
From the documentation I know that autoSize doesn't work with navigateUrl from other domains.
But i am adressing another webserver in the same domain, and autoSize still doesn't work.
However, with a page from the running application in the navigateUrl it works.

Any ideas?

Thanks

AJAX Scroll Issue with Div

I am using RadAjaxManager and RadAjaxManagerProxy for achieving AJAX in my page. I have asp:PlaceHolder which have all dynamic controls and i want to refresh those set of controls on AJAX call. I have put that in panel which i have placed in div to get the fix region with scroll bar.

<div id="dvQuestionSection" class="QuestionSection" onscroll="SetQuestionSectionScrollPos()">
    <asp:Panel ID="pnlPhFields" runat="server">
        <asp:PlaceHolder ID="phFields" runat="server"></asp:PlaceHolder>
    </asp:Panel>
</div>

After ajax call gets completed, scroll position of div gets changed. And what i have noticed is, this happens especially when I have RadEditor control in place holder and it set the scroll position so that RadEditor comes visible.

I want to be on same scroll position where I am invoking ajax call.
Any direction on this will be a great help.

Thanks

OnClientFileUploading args.set_cancel(true) behaviour question

Hi,

I have an issue where setting args.set_cancel(true) in the OnClientFileUploading event doesn't seem to cancel the upload.

I have a small working example of this.

The example checks that you are not uploading two files with the same name. Upon detecting that you are, it displays an alert and sets the cancel to true. I note however that when posting back, I still get a FileUploaded server event for each file, including the cancelled one(s).

How do I know that one of those is actually cancelled? What is the expected functionality of cancelling the upload through this method? All that seems to happen is the file indicator turns red but otherwise it seems it makes no difference to functionality.

Please help! :)
