RadInputManager Mandatory Field Validation Issue

Hi,

I have a form which contains textbox and radio button controls in which some textboxes are mandatory. I have a radio button and textbox where the textbox will be enabled when I click on the radio button. The textbox should be a mandatory field only when the textbox is enabled. When the textbox is disabled/read only, it should not be considered as a mandatory field.

But, in my scenario it is considering the disabled/readonly textbox also as mandatory field. How can change this behaviour??

Thanks,
Mahesh

Empty RadTreeNodeDragDropEventArgs on NodeDrop

Hello,

I got a problem with Drag&Drop of a TreeNode. In a simple web project this false behaviour doesn't appear. But in my bigger project I have the following problem:

I got on an aspx site a simple TreeView control...

    
                <form runat="server" id="telerik" > 
        
                    <telerik:RadScriptManager runat="server" ID="RadScriptManager1" /> 
        
                    <div> 
        
                        <telerik:RadTreeView ID="myTreeView" runat="server" EnableDragAndDrop="True" 
        
                            EnableDragAndDropBetweenNodes="true" OnNodeDrop="myTreeView_NodeDrop">  
        
                        </telerik:RadTreeView> 
        
                    </div>                  
        
                    <asp:LinkButton ID="newpagelink" Text="" OnClick="AddTab_Click" class="normal" runat="server" /> 
        
                </form>

My code behind looks like this...

    
            ...      
        
            Protected Sub myTreeView_NodeDrop(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTreeNodeDragDropEventArgs)  
        
                    Dim sourceNode As RadTreeNode = e.SourceDragNode  
        
                    Dim destNode As RadTreeNode = e.DestDragNode  
        
                    Dim dropPosition As RadTreeViewDropPosition = e.DropPosition  
        
                    If destNode IsNot Nothing Then 
        
                        If sourceNode.TreeView.SelectedNodes.Count <= 1 Then 
        
                            PerformDragAndDrop(dropPosition, sourceNode, destNode)  
        
                        ElseIf sourceNode.TreeView.SelectedNodes.Count > 1 Then 
        
                            For Each node As RadTreeNode In sourceNode.TreeView.SelectedNodes  
        
                                PerformDragAndDrop(dropPosition, node, destNode)  
        
                            Next 
        
                        End If 
        
                        destNode.Expanded = True 
        
                        sourceNode.TreeView.ClearSelectedNodes()  
        
                    End If 
        
                End Sub 
        
            ...

If i'm debugging into this event everytime the RadTreeNodeDragDropEventArgs are empty, that means, the e.SourceDragNode and the e.DestDragNode are nothing!

Does anybody has a solution for me or an idee how this can be?!

Thanks for help!!!

Best regards from Germany,
Steven***

Installing on Build Server

How do I handle licensing of RADControls-Ajax on our build server? Since licensing is per-seat, does the build server need a license?

tabs as ASP.Net pages

I would like to use the tabstrip so that each tab points to a page. I don't want the control to navigate to the page, I want the page I reference to be the content of the tab. Is this possible?

I tried using the MultiPage example, but if you specify different URL's for each tab, the control just redirects you to the referenced page.

ImageManager does not work with a custom skin

Hi,

I am using the custom skin for the RadEditor:

<

telerik:RadEditor ID="radEditor" runat="server"

Skin="WWRDefault" EnableEmbeddedSkins="false"

ToolbarMode="Default" Height="600px" Width="97%"

Visible="false" CausesValidation="False"

ToolsFile="~/DefaultRadEditorToolsFile.xml"

MaxDocumentSize="2400000" MaxImageSize="20480"

ImagesFilters="*.png,*.gif,*.jpg,*.jpeg"

DocumentsFilters="*.pdf,*.xls" />

When I select ImageManager I have the following exception:
Telerik.Web.UI.RadTreeView with ID='tree' was unable to find embedded skin with name 'WWRDefault'. Please, make sure that you spelled the skin name correctly, or if you want to use a custom skin, set EnableEmbeddedSkins=false.

Could you please let me know what I am missing?

Thank you,
Tatiana

[Solved] Google service spellchecking - when may it be implemented?

I have read the following two threads: radspell-dictionaries.aspx and thesaurus.aspx.

Can you advise me if Telerik is still planning on implementing the Google service spellchecking as well as the ability to attach directly and use the OpenOffice dictionaries, if so when is this likely to be implemented and can you provide a a general time frame (in 6 - 8 months time or in 12-18 months time)?

I am thinking of creating numerous spell checker dictionaries for my project, but I am thinking it may be prudent to wait until these features are implemented by Telerik.

Add a Node in edit mode by Default

Implemented following example at this url http://www.telerik.com/help/aspnet-ajax/general-add-node-in-edit-mode-by-default.html
cannot get to work after triying various combinations. I dont get any errors however the 3rd alert is not fired see code below. Works if i dont have an ajax panel.

Can node.startEdit() be done server side would easier.

protected void ContextMenuItemClick(object sender, RadTreeViewContextMenuEventArgs e)
{
RadTreeNode node = new RadTreeNode("NEW FOLDER", "1");
ClickedNode.Nodes.Add(node);

    node.Selected = true;
    node.ExpandParentNodes();
    string script = "HighlightNode(\"" + node.Value + "\")";
    RadAjaxManager1.ResponseScripts.Add(script);
}

<telerik:RadScriptManager ID="RadScriptManager" runat="server" />
    <telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">
       <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"/>

        <telerik:RadScriptBlock ID="rsb" runat="server">

        <script type="text/javascript">
          function HighlightNode(value)
          {
              alert(value);
              var tree = document.getElementById("<%= tvLibraryTree.ClientID %>");
              // tired $find no luck unless no ajax panel
              alert(tree);
              alert(tree.findNodeByValue(value));
              var node = tree.findNodeByValue(value);
              if (node != null) node.startEdit();
          }

RadGrid autogenerate - enablelinqexpressions and filter

I am tyring to create a report with autogenerated Radgrid and adding a Calculatedcolumn for row total. If the columns are declared in design mode and I use EnableLinqExpressions false, filter for DateTime and the calculated column works but for autogenerated columns - I get following error for DateTime filter and Calculated Column filter.

For DateTime filter:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

For GridCalculated Column the error is:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Expression of type 'System.Nullable`1[System.Int32]' cannot be used for parameter of type 'System.Object' of method 'System.String ToString(System.Object)'

Can you please suggest what can I do to fix that error. I have looked at the filtering demo examples and that also uses enablelinqexpressions = false.

Thanks.

Windows Activate TopMost

Hi:

If a have 2 windows, not maximized, I can switch between each other without any problem. I can convert each one in the topmost window.

But if I maximize one of them, after switch one time between the one maximized and the normal size window, the maximized remains as the topmost, even if I activate the normal size window. When I activate the normal size window, the titlebar of the one maximized becomes transparent, but the normal size window never converts into the topmost, I cannot see it on the fron.

Can you share a sample on how I can switch and activate between 2 windows: one maximized and one not-maximized?

Thanks in advance.
