Hello,

I am working with a RadTreeView using a node template. It is databound against a datatable.

<TELERIK:RadTreeView ID="tvOrgChart" runat="server"

DataValueField="staffmemberid" DataTextField="title" DataFieldID="staffmemberid" DataFieldParentID="supervisor">

<NodeTemplate>

<strong><%# Eval("casualname") %>,</strong> <em><%# Eval("title") %></em> <small>[<%# Eval("staffclassname") %>]</small>

</NodeTemplate>

</TELERIK:RadTreeView>

My initial question was supposed to be how can I enable editing on this tree so that only the "title" attribute is edited. It turns out that by adding DataTextField="title", that this functionality is built in!! Pretty cool!

But I do have a problem. When the edit is complete, the node still displays the original text of the template, without any of the updates to the title field. There is a great Outlook-like example showing how to implement ClientNodeEditStart and ClientNodeEdited to restore a message counter after a rename.I attempted to use this pattern.

I want to get the original displayed text, save it, and, after the edit, replace the old title with the new title. Here is the problem... in the ClientNodeEditStart event, the .get_text() does not actually return the text that is displayed on the node! With DataTextField defined, it returns the value of the specified column. Without a text value defined, it returns "System.Data.DataRowView".

How can I get the HTML that is displayed by the node??

[Solved] "Generate Local Resource" also Rewrite Telerik Tags

In order to create a new Local Resource file (RESX), I navigate to the Designer, and use the Tools --> Generate Local Resource option.

The problem is that many of my telerik tags are getting rewritten during this process. Is there a way to stop this?

No standard ASP controls demonstrate this behavior - so I am wonder if this is something on the Telerik side?

We do not use the designer view - except for this purpose - and I understand that it may just be inserting default attributes and tags that we did not write - but this adds to our code, and sometimes messes things up.

Is there a way to disable this - or a workaround?

For example, this:

<telerik:RadTextBox runat="server" ID="tCurrentAgency" Width="200px" ReadOnly="True" SkinID="defaultText">

</telerik:RadTextBox>

becomes this:

<telerik:RadTextBox runat="server" ID="tCurrentAgency"

Width="200px" ReadOnly="True" SkinID="defaultText" LabelCssClass="" LabelWidth="64px" meta:resourcekey="tCurrentAgencyResource1" Resize="None">

<EmptyMessageStyle Resize="None" />

<ReadOnlyStyle Resize="None" />

<FocusedStyle Resize="None" />

<DisabledStyle Resize="None" />

<InvalidStyle Resize="None" />

<HoveredStyle Resize="None" />

<EnabledStyle Resize="None" />

</telerik:RadTextBox>

Uploader Error

I just updated my telerik controls, and a previously working uploader is now throwing an error. When I upload a file, it proceeds to try an upload but then throws the JS error below. I can't find a solution, any ideas?

InlineInsertTemplate options

Greetings,

I changed InlineInsertTemplate to contain 2 buttons(for now) and i would like, depending on which i have clicked, to hide certain fields from Advanced Insert Template.

So i have the code :

I have tried to get SenderID in RadScheduler1_FormCreated function, but had no luck with that.

Anyone knows the solution for this issue?

If its possible to create two advanced insert forms that would`ve helped as well ,and show one depending on the button i cliked, but the whole point is to get a button id in some of these events

Thanks forward!

set reportViewer height inside radwindow

I'm trying to set the height of a reportviewer inside a RadPageView of a radwindow to fit the height of the window but if I put something light height="100%" it doesnt work at all and if a change it to a a constant height it uses that height as a margin and produces the effect in the attached image, But if I move or shake the radwindow a little bit it arranges in the way it's supposed to be.
I've already tried stuff on this thread http://www.telerik.com/forums/how-to-set-reportviewer-auto-height-d26da08c4489 but it was useless. Any idea how to solve it?
