This issue happends every now and then, however, this time I noticed that itonly happens when I left the SIS page untouched for a while. After thisexception has occurred, no matter what I click, it always respond with the sameerror. I can only close the page and open a new one.

Just a guts feelingthat this issue might be related to the session timeout interval?

Belowis the deail error message:

Urgent: Menu Item height

Hi All,

I'm trying to use some 24px x 24px images for the menu item icons and have realised that the menus expect the icons to be 16px x 16px.

What CSS do I need to change to get this work?

I'm finding that 16px icons are just too small for my purposes. Luckily I will be able to get away with 24px and not 32px icons.

Any help?

Regards,

Jon

Use Grid/Editing with external form if postback

Hi,

I use Grid control to popup my web form containing a dropdown list. When the dropdown list posts back, the value selected in the dropdown is lost. I found out that such postback actually takes the whole page posting back.

I look around and see the new feature "Grid/Editing with external form". If I add a dropdown in the EXTERNAL FORM with postback, can this form keeps my selected value after postback?

If you have any other better solution, let me know. Thanks.

Frank.

Deleting files from tree

Hello.

I have a couple issues.
Please note: The explorer mode is FileTree.

1. I can't delete folders from the tree with the client method deleteItem(path, type) (http://www.telerik.com/help/aspnet-ajax/radfileexplorer-client-side.html). In my FileBrowserContentProvider method DeleteDirectory receives a wrong path (for example: if I make a call with path "28", I receive "8" in the method; if with path "29", I receive "9"). I temporarily use client method deleteSelectedItems() but

    
            oExplorer = $find(oExplorerID);oExplorer.deleteItem(oExplorer.get_selectedItem().get_path(), oExplorer.get_selectedItem().get_type());

don't work.

2. I can't delete files from the file tree. I call deleteSelectedItems() for the file but another method (DeleteDirectory) is called from FileBrowserContentProvider with the parent path of the folder instead of the method DeleteFile. I can't delete files from the file tree without my FileBrowserContentProvider either.

    
            oExplorer = $find(oExplorerID);

            oExplorer.deleteSelectedItems();

Thanks.

Programatic Grid creation with RadToolTip on column

We are creating a Grid dynamically based upon an ad-hoc definition of selected columns and data sources by the end-user. We have a number of columns which we need to offer the user "ToolTip" information which is database driven and specific to the value in the row.

I've been looking at building a new class which implements ITemplate and adds the field value (using a label) and attaches a RadToolTip to the label in the cell, but it seems like I have to implement the formatting/aggregates/etc on my own.

Another thought I had would be to use an BoundColumn, but override the DataBinding event (or to add an additional event to the firing of DataBind) and attach the tooltip there, but it seems like I can't. We have source code access and I can see how it's done behind the scenes, but I'm just not sure where to do it and still use the released controls.

Right now our columns inherit from the base GridColumns (GridBoundColumn, GridHyperlinkColumn) and get their values on the fly from from our settings system. Here's an example:

    
                    public class BoundGridColumn : Telerik.Web.UI.GridBoundColumn  
        
                {  
        
                    public BoundGridColumn()  
        
                    {  
        
                    }  
        
                    public BoundGridColumn(string column)  
        
                    {  
        
                            this.DataField = column;  
        
                            this.UniqueName = column;  
        
                            this.SortExpression = column;  
        
                            this.HeaderText = Utility.GetSetting(column + ".Header");  
        
                            if (Utility.GetSetting(column + ".Width").Length > 0)  
        
                            {  
        
                                int _width = Convert.ToInt32(Utility.GetSetting(column + ".Width"));  
        
                                this.HeaderStyle.Width = Unit.Pixel(_width);  
        
                                this.FooterStyle.Width = Unit.Pixel(_width);  
        
                                this.ItemStyle.Width = Unit.Pixel(_width);  
        
                            }  
        
                            else  
        
                            {  
        
                                this.HeaderStyle.Width = Unit.Pixel(100);  
        
                                this.FooterStyle.Width = Unit.Pixel(100);  
        
                                this.ItemStyle.Width = Unit.Pixel(100);  
        
                            }  
        
                            if (Utility.GetSetting(column + ".Item.Align").Length > 0)  
        
                                this.ItemStyle.HorizontalAlign = (HorizontalAlign)Enum.Parse(typeof(HorizontalAlign) , (Utility.GetSetting(column + ".Item.Align")));  
        
                            if (Utility.GetSetting(column + ".Footer.Align").Length > 0)  
        
                                this.FooterStyle.HorizontalAlign = (HorizontalAlign)Enum.Parse(typeof(HorizontalAlign) , (Utility.GetSetting(column + ".Footer.Align")));  
        
                            if (Utility.GetSetting(column + ".Header.Align").Length > 0)  
        
                                this.HeaderStyle.HorizontalAlign = (HorizontalAlign)Enum.Parse(typeof(HorizontalAlign) , (Utility.GetSetting(column + ".Header.Align")));  
        
                            // = Unit.Pixel(_width);  
        
                            if (Utility.GetSetting(column + ".Visible").Length > 0)  
        
                                this.Visible = Convert.ToBoolean(Utility.GetSetting(column + ".Visible"));  
        
                            this.DataFormatString = Utility.GetSetting(column + ".Format");  
        
                            this.DataType = System.Type.GetType(Utility.GetSetting(column + ".DataType"));  
        
                            if (Utility.GetSetting(column + ".Aggregate").Length > 0)  
        
                                this.Aggregate = (GridAggregateFunction)Enum.Parse(typeof(GridAggregateFunction) , Utility.GetSetting(column + ".Aggregate"));  
        
                            if (Utility.GetSetting(column + ".AllowFiltering").Length > 0)  
        
                                this.AllowFiltering = Convert.ToBoolean(Utility.GetSetting(column + ".AllowFiltering"));  
        
                            this.Groupable = true;  
        
                            this.ItemStyle.Wrap = false;  
        
                        }

So where/how can I attach a value specific tooltip to this column

Radio button onselectedIdexChanged -> table.visible=true

Hello
I have a RadioButtonList and a table named "TableDateCalendrierCroisement" in a form. When I select the value "2" (which is "oui") on my RadioButtonList, I want the table be visible, when I select the value "1" (which is "non") then I want my table.visible=false. I do it in code behind but I would like to do it with ajax. Is it possible?
Thanks you!

this._folderCache JS error

I keep getting the following error:

this._folderCache is undefined

It appears to be coming from the _changeCurrentFolder function: this line in the RadFileExplorer javascript:

    
            if(this._folderCache[e]!=null&&!f){this._onCallbackResponse(this._folderCache[e],j);}

Now, this perplexes me because it appears that the FileExplorer works correctly in all other regards except when I initiate some action that refreshes the left hand tree view pane. (Which by the way, loads correctly as I interact with opening folders...)

Deleting a file, folder, or even clicking the refresh icon causes the above error.

So my question is - How could this variable not be defined (it appears to be defined in the initialization of the object, javascript side)? Is there some way for me to debug this on my end that isn't apparent to me? I am using a custom content provider for this and so far I am happy with everything else other than this!

Thanks
