The old node Text returns back after editing

The scenario :
My customer wants the tree node text to be edited after some button the page clicked. The scenario is as follows:
1 button clicked
2 selected node in tree became editable (displayed inside textbox)
3 after losing focus the changes are saved

My Code :
When i populate the tree nodes i set the

AllowEdit property to false - to prevent node became editable when clicked.
in the button_Click eventhandler i put call to

startNodeInEditMode function

as in the following code:

public void startNodeInEditMode(string nodeValue)

{

string js = "Sys.Application.add_load(editNode); function editNode(){ ";

js += "var tree = $find(\"" + RadTreeView1.ClientID + "\");";

js += "var node = tree.get_selectedNode();";

js += "if (node) node.startEdit();";

js += "Sys.Application.remove_load(editNode);};";

RadScriptManager.RegisterStartupScript(Page, Page.GetType(), "nodeEdit", js, true);

}

protected void RadTreeView1_NodeEdit(object sender, RadTreeNodeEditEventArgs e)

{

e.Node.Text = e.Text;

The Problem :
The changed text of the node returns back to old version of text (the changes suddenly disappear after few seconds and old text appear)
Althougt i see that changes are saved in db inside the RadTreeView1_NodeEdit function.

Please help

Button in RadGrid requires two clicks

Hi,

I'm creating a RadGrid totally programmatically in the code behind in a server control. This grid contains a GridButtonColumn that triggers a routine in the code behind. It works, but the first time the page is rendered, the button requires two clicks. It does postback on the first click, but the command handler is not called. On the second click, the command handler is called. Any ideas what I'm doing wrong. Thanks in advance for your help.

Upload file exists, automatically rename and save

Required functionality, on upload from the file explorer upload dialog if the document being uploaded already exists(and overwrite files is not selected), automatically rename the document with a new version number, and upload it. How do I cancel the validation that happens between the ItemCommand() and custom content provider method StoreFile()? Currently, ItemCommand() method fires, I am not able to change the upload.filename (read only) in this method. The validation then fires preventing the StoreFile() method, so I am not able to modify the filename in this method either. I would really like to remove this automated validation, and add my own.

Thanks!

OnGroupExpanding extract group information

I have a requirement for a project that I'm having some difficulty getting to work. I've looked at the following post, http://www.telerik.com/community/forums/aspnet-ajax/grid/client-side-expand-collapse-of-group.aspx, but it only takes me so far. For my page, I have a grid that is configured for client-side grouping. I have a requirement that the expanded groups are persisted on grid rebind. There is a control on the page that allows the user to select from a list of items that translate to the groups in the grid. So, the user selects 3 items in the list and there are 3 groups of those selected items in the grid, the user selects 5 items from the list and there are 5 groups in the grid, etc. In other words the number of groups is variable based on user selection.
I've set up a web service to handle the persisting of the group information via ajax callback from the page, and that all works fine. The problem I'm having is that there isn't any way to get the selected group information in the OnGroupExpanded or OnGroupCollapsed events. It appears that the sender is the grid itself and the event args are empty? I currently have the following code, based on the link above:

<telerik:RadGrid ...>

<ClientSettings EnableRowHoverStyle="false">

<ClientEvents OnGroupExpanded="groupExpanded" />

</ClientSettings>

...

</telerik:RadGrid>



function

groupExpanded(sender, e) {

var grid = $find(sender.get_id());

var expandedGroupItems = grid._expandedGroupItems;

var lastItemId = expandedGroupItems[expandedGroupItems.length - 1];

alert("Owner TableView: " + lastItemId.split('!')[0]);

alert("Table Row Index : " + lastItemId.split('!')[1]);

}

In the example, it shows getting the row index by parsing the item ID and then this ID can be used server-side to set the row expansion. However with variable groups, that ID is also variable (I've tested as such, the IDs change as groups are added or removed). Is there really no way to get at the group item that was expanded or collapsed directly? What I'd like, is to use our own internal unique id for the group, but it doesn't look like any group information is exposed at all in these events.

Also, I'd like to say that the documentation for OnGroupsExpanded and OnGroupsCollapsed is incorrect. It states that the sender is a GridDataItem, when in fact it is the grid itself. It is a bit confusing.

Any and all help would be greatly appreciated.

Thanks,

-Matt.

Delete row in table doesn't account for row span

Hi,

if you follow these steps in RadEditor:

1. Add a Table (e.g. 3x3 sized)
2. Set focus on the top right cell
3. Click on "Merge Cells Vertically" button
4. Set focus on the central cell (the second row)
5. Click on "Delete Row" button

The resulting table is a mess. This is because "delete row" doesn't check whether some of the cells on top of the affected row have a rowspan that needs to be decremented.

RadUploadProgressHandler registration error accross domains

Hi

I am successfully running a .Net2 application on a server which works pefectly with RadUploadProgressHandler. But When I try to access the same application accross domains the I receive an error when trying to Upload a file. The error is :
Did you register the RadUploadProgressHandler in web.config?
Please, see the help for more details: RadUpload 2.x - Using RadUpload - Configuration - RadUploadProgressHandler.

I don't understand why it works on the internal domain that the application is hosted on but throws error when the same application is accessed from another domain.

I have the following in my web config.

<

httpHandlers>

<

add verb="*" path="Telerik.RadUploadProgressHandler.aspx" type="Telerik.WebControls.RadUploadProgressHandler, RadUpload.Net2"/>

<

add verb="POST,GET" path="csharpwrapper/*.ashx" type="Ajax.PageHandlerFactory, Ajax"/>

how to log "oldvalue" and "newvalue" when grid inserted/deleted/updated

Hello.
I used RadGrid with declarative binding to SqlDataSource.
I need to store old and new values in log table when I make insert/delete/update operation.
I can handle RadGrid_UpdateCommand event like this:

protected void RadGrid1_UpdateCommand(object sender, GridCommandEventArgs e)

{

GridEditableItem editItem = (GridEditableItem)e.Item;

//extract the edited values in a Hashtable

Hashtable values = new Hashtable();

editItem.ExtractValues(values);

//get the saved old values before editing

Hashtable oldValues = (Hashtable)editItem.SavedOldValues;

//insert data to Database

//...

}

but this event fires before real operation in database and I don`t know if there is an error in current operation in DB or not.
Can anybody help?
