[Solved] Question about navigating nodes of radtree.GetAllNodes()...

I have a tree that is 7-8 levels deep. I decided that node levels 0,1,2,3 need to have thier expand/collapse ability disabled and I did it like this:

    
            foreach (RadTreeNode node in radtree.GetAllNodes())  
        
            {  
        
                int intTest = node.Level;  
        
                node.Expanded = true;  
        
                if(intTest <= 3)  
        
                {  
        
                    node.Enabled = false;  
        
                    node.ForeColor = System.Drawing.Color.Black;  
        
                }  
        
            }

What I want to know, what property on RadTreeNode lets me change the cursor style? I was thinking it was RadTreeNode.Attributes["cursor"] = "pointer"; but this doesnt seem to work.

radgrid and loading panel

Hello

I have a grouped radgrid. When the one of the groups in the grid is expanded or collapsed the grid makes an ajax postback to the server to populate the expanded group. The postback uses a rad loading panel. The problem I am having is that the rad loading panel covers the entire grid when the user expands a group which makes the grid effectively disappear. Is there anyway to have the loading panel appear just on the space where the details table will appear or failing that to at least keep the column headers of teh grid visible

i'm using q3 2008

thanks

Paste issue for Firefox 3.0

Clicking on the "paste" toolbar button in Firefox, a dialog appears which says "Please use CTRL+V to Paste". But when one uses the shortcut CTRL+V, the same dialog appears again! This instruction is useless and hence, nobody can paste content into the editor field. The only way is to use the "paste as plain text". But clearly, this is not the same.

In ToolsFile.xml, the button is defined by <tool name="Paste" shortcut="CTRL+V" />.

Surprisingly enough, this issue occurs only on some machines, but all have the same configuration.

FireFox and HeaderStyle issue

Currently, FireFox doesn't support using "em" units in the "width" attribute of COL elements. This presents a problem because the HeaderStyle.Width property renders in FireFox like so:

    
            <colgroup> 
        
              <col width="25em"/>  
        
              <col width="5em"/>  
        
              <col width="5em"/>  
        
            </colgroup>

However, em units ARE supported in FireFox if the widths are set using the "style" attribute:

    
            <colgroup> 
        
              <col style="width:25em"/>  
        
              <col style="width:5em"/>  
        
              <col style="width:5em"/>  
        
            </colgroup>

Interestingly, width attributes are rendered in IE without the "em":

    
            <colgroup>    
        
              <col width="25"/>     
        
              <col width="5"/>     
        
              <col width="5"/>     
        
            </colgroup>

Create thumbnail in Image Manager

Is anyone familiar with the "create thumbnail" functionality of the Image Manager?

I open the Image Manager
Choose an image URL
Upload an image
Select the uploaded image and click on the "Create thumbnail" icon in the Image Manager

In most of the cases I get a proposed with and height of 35 Pixel although "Constrain proportions" is ticked and the image has a 4 : 3 image proportion.

I then close the Image Manager and reopen it, select the uploaded image and click the "Create thumbnail" icon... and magic: the original width and height of the uploaded image is shown (and the state of "Constrain proportions" was kept).

I then change the width to something smaller than the uploaded image and the height is adjusted correctly. Clicking the "Create" button generates my thumbnail. But if I select now the newly generated thumbnail, the image dimensions displayed are 35 x 35 pixel :( Clicking the "Insert" button adds the new generated image to my html content and ...the dimension are suddenly correct.

I then reopened the Image Manager to generate a thumbnail which was a little bit wider than the one generated in the first round. So I selected the uploaded image (original dimensions correctly displayed, but if I clicked the original image a second time the dimensions always change to 35 x 35 px), ticked "Overwrite if file with such name exists?", changed the width to something larger than for the first generated thumbnail, clicked "Create", selected the new thumbnail and inserted it to my html content... and what I got inserted was the small thumbnail of the first round :(

Only after checking in the publishing page and edit it afterwards again (close the editor) I was able to select the larger thumbnail.

I presume the Image Manager to have two problems:

Image dimensions displayed in the "create thumbnail" area are not always displayed correctly. Reproduceable is the problem when choosing an image, change to create thumbnail and click the image again on the left hand side -> dimensions always change to 35 x 35 Pixel and the only way to see the correct dimensions is to close and reopen the Image Manager
Once a thumbnail is generated it looks like it get's cached ? until the Rad editor is closed. When overwriting the thumbnail the new thumbnail can only be inserted after closing and reopening the Rad editor.

Are these issues already known?
