Find selected node in client script..

I am using the following javascript function

function

OnEndRequest(sender,args) {

alert();

var treeviewInstance = $find("<%= treeFramework.ClientID %>");

alert(treeviewInstance);

var selectedNode = treeviewInstance.getSelectedNode();

if (selectedNode != null)

{

selectedNode.ScrollIntoView();

}

}

It gives an errror that getSelectedNode();method is not supported..

I tried using get_SelectedNode() but no help.

Actually i want to scroll to selected node on ajax request..

Grid in AJAX Panel

I have a grid with templated columns inside an AJAX panel. This column has a computed value. This causes a run-time error stating that the controls can not be modified because there is a code block within the controls collection. If I take the grid out of the panel it works fine but I only want to update the grid though. How do I get around this or fix it? Here is my column and it is in a grid contained in a standard AJAX panel.

    
                                <telerik:GridTemplateColumn UniqueName="DateLocked" Groupable="false" DataField="DateLocked" SortExpression="DateLocked" HeaderText="Date Locked"> 
        
                                    <ItemTemplate> 
        
                                        <asp:Label Text='<%# (Convert.ToDateTime(DataBinder.Eval(Container.DataItem, "DateLocked")) > DateTime.MinValue.AddYears(1))? DataBinder.Eval(Container.DataItem, "DateLocked") : "N/A" %>' ID="DateLockedLabel" runat="server"></asp:Label> 
        
                                    </ItemTemplate> 
        
                                </telerik:GridTemplateColumn>

Associated with this error is the fact that the AJAX manager configuration screen does not list the controls on the page so that I can set the properties to let the update panel handle the AJAX calls for the grid.

[Solved] How can I Modify HeaderText but keep Ajax sorting?

When I followed the procedure below to dynamically modify the HeaderText in a column I found that the sorting feature for that column was lost.

http://www.telerik.com/community/forums/aspnet-ajax/grid/radgrid-headertext.aspx

Is there a fix for the problem.

Note: I've added more detail on this in the thread for the actual link above.

Hi!

Me again!

I want to filter in a Hierarchy grid by "Tm" column
<telerik:GridTemplateColumn DataField="Tm" UniqueName="Tm" HeaderText="Light">

I follow this demo: http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filtertemplate/defaultcs.aspx.

No Hierarchy, so good.
But when I filter with Hierarchy , server error: Object reference not set to an instance of an object .

I don't konw whether there is some different when filter in Hierarchy or not?

Later I will post a screenshot to describe the situation more clearly.

Thank you!

Best wishes
Airad

<

Image Manager return object.

Greetings:

We've developed a custom image chooser using the DialogOpener. Which we take the resulting args object and retrieve the src path and URL encode it and pass the ImageUrl to our thumbnail generator.

We build the script server side and register it to the page.

We had no issues in IE6, IE7 until the most recent updates.

function callBackFunction(sender, args){

var selectedItem = args.value.attributes[0].value;

..... custom code ....

}

the problem is, with the most recent updates, in IE7 or IE8 compatibility mode it returns null. this works great in IE 8, and FF 3.x

Would there be any chance there is another property that could be available that I am not aware of?

Thanks

2. is there a way to hide the expand/collaps column itself if none of the rows has sub-items
3. I would like to add a collaps All rows/Expand All rows button

Thanks in advance, Eyal.
