Hi,

I am making a Prometheus Portal, and when I add a dock to the page, and then call up the page again, tehre is the dock that I placed, which can close and collapse and what not, but there is also a duplicate of that dock underneath it, where the dock commands do not work, and I cannot drag or close it. Why is this happening?

also, Whenever I try to perform an action in my embedded Crystal Report Viewer, I get an Invalid JSON Primitive "." Error.

Can anyone please help me?

Clientside drag & drop and Serverside synchronization

Hi,
I have a Tree using clientside drag and drop and load on demand with webservice.
How can I update the Tree-Structure on the Serverside with calling a webmethod at the end of the client-event onNodeDropping?

Example:

    
            function onNodeDropping(sender, eventArgs) 
        
                    { 
        
                        var destinationNode = eventArgs.get_destNode();                                         
        
                        if(destinationNode)   
        
                        {    
        
                            var sourceNodes = eventArgs.get_sourceNodes();  
        
                            var firstTreeView = sourceNodes[0].get_treeView(); 
        
                            var secondTreeView = destinationNode.get_treeView(); 
        
                            var firstTreeViewID= sourceNodes[0].get_treeView().get_id();   
        
                            var secondTreeViewID = destinationNode.get_treeView().get_id();   
        
                            firstTreeView.trackChanges();   
        
                            secondTreeView.trackChanges();   
        
                               var type = "over"; 
        
                            for (var i = 0; i < sourceNodes.length; i++)   
        
                            {   
        
                                var sourceNode = sourceNodes[i];   
        
                                //sourceNode.get_parent().get_nodes().remove(sourceNode);                        
        
                                if(eventArgs.get_dropPosition() == "over")  
        
                                { 
        
                                    destinationNode.get_nodes().add(sourceNode);                                                         
        
                                } 
        
                                if(eventArgs.get_dropPosition() == "above")  
        
                                { 
        
                                    insertBefore(destinationNode, sourceNode);   
        
                                    type = "above"; 
        
                                } 
        
                                if(eventArgs.get_dropPosition() == "below")   
        
                                { 
        
                                    insertAfter(destinationNode, sourceNode);   
        
                                    type = "below"; 
        
                                } 
        
                            }   
        
                            destinationNode.set_expanded(true);   
        
                            firstTreeView.commitChanges();   
        
                            secondTreeView.commitChanges();  
        
                            // Save State Serverside 
        
                            WebInterface._webServices.MainAjaxServices.InsertNodes(eventArgs, "type", null, null);   
        
                        }  
        
                    }

and Serverside:

    
            [WebMethod( EnableSession = true )] 
        
                    [ScriptMethod] 
        
                    public void InsertNodes( RadTreeNodeDragDropEventArgs NodeEvent, string type ) 
        
                    { 
        
                        // Update the Tree-XMl Serverside 
        
                    }

Is it possible to get the clientside Eventargs to Serverside?

Thank you very much
Christian

Invalid webresource with Custom Skin

I have created a custom skin for my Editor. It works as expected except for one item. When a page loads with the editor on it I get an error thrown (through Elmah) :

System.Web.HttpException: This is an invalid webresource request

Here is the editor code:

<

telerik:RadEditor ID="RadTextBoxMessageP" OnClientLoad="OnClientLoad" Runat=server Skin="DWDS" EnableEmbeddedSkins="false" ToolsFile="/ToolsFileLimited.xml" />

I also have the following declared:

<

link href="/Skins/DWDS/Editor.DWDS.css" rel="stylesheet" type="text/css" />

<

script type="text/javascript">

function

OnClientLoad(editor, args)

{

var style = editor.get_ContentArea().style;

style.backgroundImage =

"none";

}

</

script>

Any ideas of why I am getting this error? I have done skins for several other controls and haven't had a probelm with them.

Thanks

[Solved] RadNumericTextBox Overflow Assigning Double.MinValue to Value Property

Working with the RadNumericTextBox, I am trying to assign the absolute floor for a double using Double.MinValue to the TextBox Value property (myRadNumericTextBox.Value = Double.MinValue). It throws a "InvalidCastException" for Text property cannot be set. Value was either too large or too small for a Double. I have no problem assigning Int32.MinValue. This occurs with MaxValue for both, also. Any ideas?

Thanks.

cannot enable context menus on node once disabled

I cannot enable context menus on node once disabled. I would like to be able to enable them.

I will open a ticket and send you a picture
running verision 2007.3.1328.20

Here is your implementation

public bool EnableContextMenu
{
    get
    {
        return (this.ViewState["EnableContextMenu"] == null);
    }
    set
    {
        this.ViewState["EnableContextMenu"] = value;
    }

CustomValidator on GridCheckBox

Control 'ValidatePhoneIsPrimary' referenced by the ControlToValidate property of '' cannot be validated.

This is the error I get on my custom validator. If I change the validator to a different control to validate - like a textboxcontrol - then it works fine. But it won't work for my checkbox.

<telerik:GridCheckBoxColumn HeaderText="Primary" DataType="System.Boolean" DataField="IsPrimary" CurrentFilterFunction="NoFilter" FilterListOptions="VaryByDataType" ForceExtractValue="None" UniqueName="PhoneIsPrimary">
<HeaderStyle Width="10px" />
</telerik:GridCheckBoxColumn>

protected void RadGrid1_ItemCreated1(object sender, GridItemEventArgs e)

{

if (e.Item.OwnerTableView.Name == "Phone")
    { if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            GridEditableItem item2a = e.Item as GridEditableItem;

GridCheckBoxColumnEditor editor2a = (GridCheckBoxColumnEditor)item2a.EditManager.GetColumnEditor("PhoneIsPrimary");

TableCell cell2a = (TableCell)editor2a.CheckBoxControl.Parent;

CustomValidator validator2a = new CustomValidator();

editor2a.CheckBoxControl.ID =

"ValidatePhoneIsPrimary";

validator2a.ControlToValidate = editor2a.CheckBoxControl.ID;

validator2a.ErrorMessage =

"Inactive or Closed Phone can not be Primary Phone";

validator2a.ServerValidate +=

new ServerValidateEventHandler(CustomValidator1_ServerValidate);

cell2a.Controls.Add(validator2a);

}}}

protected void CustomValidator1_ServerValidate(object source, System.Web.UI.WebControls.ServerValidateEventArgs args)

{

if (args.Value == "0"){args.IsValid = true;}}

If I can get this working I will also need to look at and compare args.value to my combobox dropdown selected value - I am not sure how to retrieve that value here in my validation routine.

Slow Window Resize

Hi,

Has anyone noticed a problem with the splitter when resizing the browser window? If you have a large amount of content in a pane, then you maximise the window, it can take a minute or more for the browser window to redraw properly. You have to have a huge amount of content i.e. a 1500 row table in one pane, 1500 graphics in another pane. Yes we do need this as we are writing a Gantt Chart and a project plan for some of our customers can easily have double this amount of tasks.

If I remove the splitter and implement my own DIV's, it takes it 2 seconds to redraw.

I really like the display and functionality behind the splitter but I cannot use it unless someone can tell me how to correct this problem! It must be something to do with the splitter code?

Regards,

Mark

Accessing Treeview from iframe

Hello everybody!
I know my question is not that telerik related, but probably you guys already needed something like this:
I have a mainpage with a radtreeview and an iframe. By clicking on a treenode, I load a new aspx page into the iframe. Now I want to access the radtreeview from the iframe, in order to update the tree.

Does anybody know any possibilities to access controls from "parent"frames ?

thx in advance & kind regards
