Getting Radspell error 500 when using MSWordProvider.

I'm getting a 500 server error when I am using the MSWordProvider (the other providers work ok). I have word installed correctly on the server so I don't think that is the issue. Here is the full text of the error:

/Telerik.RadSpellCheckHandler.ashx undefined

Obeject Reference not set to an instance of an object.

Exception information:
    Exception type: NullReferenceException
    Exception message: Object reference not set to an instance of an object.

Programmatic/Dynamic control of ReadOnly for GridTemplateColumn

Is it possible to change the ReadOnly property of a GridTemplateColumn by dynamic programmatic control?

If so, what is the recommended way to do this? I looked for a code snippet but have not found it yet...

I want to develop a *.ascx control built using Telerik RadGrid such that there are various GridTemplateColumns for which I can dynamically change the ReadOnly status. Then I can put the *.ascx control with ReadOnly=true on certain *.aspx web pages and ReadOnly=False on other *.aspx web pages.

Thanks

Some issues with RadEditor

Hi,

I use the RadEditor in a number of ways in our (rather complex) web application, and I have come across several issues along the way.

I use "radEditor.Modules.Clear()" to remove the empty panel beneath the editor box. This works fine, except when the editor is created dynamically, then the empty panel is visible regardless. Is there another way to hide it? And why does it show up at all, since it's empty anyway?
I use the RealFontSize tool to set font size, and it sort of works, BUT, when I later open the editor and select the text with, say, font size 14px, the font size DropDownBox will show 4 and not 14px. Presumably the DropDownBox converts to standard HTML font size when reading the selection formatting. To make it even more confusing the HTML code shows 14pt, not pixels (px)! Very confusing for the people using the editor. Any ideas on how to solve this and make it work consistently?

Related to this, i would prefer for the tool to always show points (pt) for font size, not pixels (px). Is this possible? Not a great issue, but it would be nice.

I hope my explanations are clear enough to understand.
Regards,
TJ

Alternate rows AND selected column

In the grid I can specify alternate row CSS to add visual separation between rows
I can also add a CSS to the sorted column to add visual cue which column is currently sorted

So lets say I have alternating rows with white/gray/white/gray background
I also have CSS for sorted column that turns background of the sorted column to blue. All cells in sorted column now have blue background. Compare to nicely white/gray/white/gray schema of the unsorted column it looks ugly.

Question: How can I can specify alternate row CSS for the sorted column? So in the sample above I would get white/gray/white/gray for unsorted columns and dark blue/ligh blue/dark blue/light blue for sorted ones?

Thank you

Radwindow unable to retain the various properties set in .aspx page

Hi,
Currently I working in a scenario where RAD WINDOW is present in Parent.aspx and we have child.aspx in IFRAME of Parent.aspx....
I have provided a link in child.aspx which opens the radwindow of parent.aspx.

Problem: Now open the radwindow in parent clicking on link in child. It opens fine. Close the window. Again click the link. Now rad window is distorted. It's unable to retain the attributes like Height, Width, Behaviour etc... set in .aspx .

i.e second time when you open rad window it's a problem.

Code is as follows:
Parent.aspx

    <rad:RadScriptManager ID="RadScriptManager1" runat="server" OutputCompression="AutoDetect" >
    </rad:RadScriptManager>
        <rad:RadWindowManager Skin="Vista" DestroyOnClose="true" id="Singleton" runat="server">
            <windows>
                <rad:RadWindow Runat="server" Modal="true" Height="450" Width="850" Visible="true" VisibleStatusbar="false" Title="SumTotal" EnableEmbeddedSkins="false" Skin="Vista" VisibleTitlebar ="true" Behaviors="Close" Behavior="Close" ID="DialogWindow"></rad:RadWindow>
            </windows>
        </rad:RadWindowManager>

child.aspx

<div id="Div1" runat="server">
   <script type="text/javascript">
        function openWindow()
        {
             var oWindow = null;
             var strURL = "LMS_User_ExceptionDetail.aspx?EmpID=5195&EmpName=Emily%20Arroyo&ViewDataMode=0";
             oWindow = window.parent.radopen(strURL, "DialogWindow");
        }
    </script>
</div>

<a href='javascript:openWindow();'>test</a>

Disabling Auto-Open on Hover

Greetings,

Anybody know if there is a way to disable the auto-open that happens during drag & drop when the user hovers over the destination node?

I am only allowing nodes to be dropped within the same parent node (reordering) and auto-open gives the impression that they should be able to drop it under a new parent...

Thanks in advance for any suggestions!

[Solved] Unable to catch node expansion after creating its first child and expanding in client side code

Hi again,

it appears that the ClientNodeExpanding event is not fired when a node that has no children gets a child, and is then expanded with node.expand(). It also doesn't fire with node.set_expanded(true). Here is a sample code:

    
                    var retvals = retval.split("|"); /* retval is a string such as :
        
            "10879|Produktgrupp «Ny produktgrupp»|PRODUKTGRUPP|/Icons/TreeView/ImageCreate.aspx?nodetype=PRODUKTGRUPP&alias=False&icontype=normal|/Icons/TreeView/ImageCreate.aspx?nodetype=PRODUKTGRUPP&alias=False&icontype=expanded|Ny produktgrupp" */   
        
                    var node_id = retvals[0]; 
        
                    var tooltip = retvals[1]; 
        
                    var category = retvals[2]; 
        
                    var imageurl = retvals[3]; 
        
                    var expimageurl = retvals[4]; 
        
                    var nodename = retvals[5]; 
        
                    var node = new Telerik.Web.UI.RadTreeNode();  
        
                    node.set_text(nodename.replace(/</g,"&lt;").replace(/>/g, "&gt;")); 
        
                    node.set_target("content"); 
        
                    node.set_value(node_id);     
        
                    var navurl = "content.aspx?id_catalogue=1&data_id_node="+node_id+"&id_category="+category+"&tree_id_node="+node_id; 
        
                    node.set_navigateUrl(navurl);    
        
                    node.set_imageUrl(imageurl); 
        
                    node.set_expandedImageUrl(expimageurl); 
        
                    node.set_contextMenuID(category); 
        
                    node.set_category(category);         
        
            // g_parent_node is a global variable with the parent node
        
                    g_parent_node.get_nodes().insert(0, node); 
        
                    node.get_textElement().title = tooltip; 
        
                    if (!g_parent_node.get_expanded()) {             
        
                        g_parent_node.expand(); 

            /* If g_parent_node had no childnodes before I added one in the code above, 

            this expansion can not be caught!! Nither ClientNodeExpanding nor ClientNodeExpanded is fired. But g_parent_node is actually expanded! */
        
                    }

If I do g_parent_node.set_expandMode(Telerik.Web.UI.TreeNodeExpandMode.ServerSideCallBack) before expanding, the ClientNodePopulated event is fired, but that is not what I want.

Regards,
Fredrik

[Solved] Setting previous values with Custom Edit Forms using rad combo/text boxes

I have am using a custom edit form to update & insert information in my radgrid which contains 3 radcomboboxes & 1 radtextbox. Update works great, edit works but it doesn't set the default values of the drop downs to the current values. I am NOT using auto insert/update/delete. I can set the text value by doing:

    
            Text='<%# Eval( "Description" ) %>'

But if I try this with the comboboxes and the "SelectedValue=" I get a "Selection out of range Parameter:value" error. I am binding my controls from db information in a hooked up RadGrid1_ItemDataBound method. I'm thinking I have to set the SelectedValue somewhere in this method, after something like:

    
            GridItem gridItem = e.Item as GridItem; 
        
            if (!gridItem.OwnerTableView.IsItemInserted)

then where do I go from here? I've spent too long looking through examples and searching this forum, so I apologize if this is easy or should have been easy to find out how.
Thanks.
