Selecting Wrong Index on Ajaxified RadGrid

I've got a RadGrid inside of a Rad AjaxPanel. When I click to edit a row, the radgrid databinds (AJAX) and then enters edit mode.

So if I load the page, and then another user creates a new record, and then I click edit on the first record (in my grid), the grid databinds, switches to edit mode and index 0 is selected (which is the newly created record...not the original record I clicked on).

Any thoughts on this?

FileExplorer path issue

Hello,

I'm having some problems with my directory path on RadFileExplorer. I'm trying to use the path "\\ftp\ftp\" but it won't load any files or directories, it only loads empty.

Here's some code to analyze:

    
            <telerik:RadFileExplorer ID="FileExplorer1" runat="server" Width="700" Height="500" />

    
            if (!IsPostBack) 
        
            { 
        
                FileExplorer1.Configuration.ContentProviderTypeName = typeof(CustomColumnsContentProvider).AssemblyQualifiedName; 
        
                FileExplorer1.InitialPath = Page.ResolveUrl(@"\\ftp\ftp\" ); 
        
                FileExplorer1.Configuration.DeletePaths = new string[] { @"\\ftp\ftp\" }; 
        
                FileExplorer1.Configuration.UploadPaths = new string[] { @"\\ftp\ftp\" }; 
        
                FileExplorer1.Configuration.ViewPaths = new string[] { @"\\ftp\ftp\" }; 
        
            } 
        
            AddDateColumns();

    
            public class CustomColumnsContentProvider : FileSystemContentProvider 
        
            { 
        
                public CustomColumnsContentProvider(HttpContext context, string[] searchPatterns, string[] viewPaths, string[] uploadPaths, string[] deletePaths, string selectedUrl, string selectedItemTag) 
        
                    : base(context, searchPatterns, viewPaths, uploadPaths, deletePaths, selectedUrl, selectedItemTag) 
        
                { 
        
                    // Declaring a constructor is required when creating a custom content provider class 
        
                } 
        
                public override DirectoryItem ResolveDirectory(string path) 
        
                { 
        
                    // Update all file items with the additional information (date, owner) 
        
                    DirectoryItem oldItem = base.ResolveDirectory(path); 
        
                    foreach (FileItem fileItem in oldItem.Files) 
        
                    { 
        
                        // Get the information from the physical file 
        
                        FileInfo fInfo = new FileInfo(Context.Server.MapPath(VirtualPathUtility.AppendTrailingSlash(oldItem.Path) + fileItem.Name)); 
        
                        // Add the information to the attributes collection of the item. It will be automatically picked up by the FileExplorer 
        
                        // If the name attribute matches the unique name of a grid column 
        
                        fileItem.Attributes.Add("Date", fInfo.CreationTime.ToString()); 
        
                    } 
        
                    return oldItem; 
        
                } 
        
                public override DirectoryItem ResolveRootDirectoryAsTree(string path) 
        
                { 
        
                    // Update all directory items with the additional information (date, owner) 
        
                    DirectoryItem oldItem = base.ResolveRootDirectoryAsTree(path); 
        
                    foreach (DirectoryItem dirItem in oldItem.Directories) 
        
                    { 
        
                        // Get the information from the physical directory 
        
                        DirectoryInfo dInfo = new DirectoryInfo(Context.Server.MapPath(VirtualPathUtility.AppendTrailingSlash(dirItem.Path))); 
        
                        // Add the information to the attributes collection of the item. It will be automatically picked up by the FileExplorer 
        
                        // If the name attribute matches the unique name of a grid column 
        
                        dirItem.Attributes.Add("Date", dInfo.LastWriteTime.ToString()); 
        
                    } 
        
                    return oldItem; 
        
                } 
        
            }

How come the "\\ftp\ftp\" path doesn't work?
And if I don't comment off the code:

    
            FileExplorer1.Configuration.ContentProviderTypeName = typeof(CustomColumnsContentProvider).AssemblyQualifiedName;

I get an error at:

    
            DirectoryItem oldItem = base.ResolveDirectory(path);

Saying that oldItem is null.

I don't believe there's anything wrong with the path string, because when I try the follow code:

    
            DirectoryInfo di = new DirectoryInfo("\\ftp\ftp\"); 
        
             FileInfo[] rgFiles = di.GetFiles("*.*"); 
        
             foreach(FileInfo fi in rgFiles) 
        
             { 
        
              Response.Write("<br><a href=" + fi.Name + ">" + fi.Name + "</a>");        
        
             }

I get the correct files listed on that path.

I even tried Impersonating an account before using the paths, but it still doesn't work.

I hope there's sufficient information, please help.

Thanks in advance

RadGrid.MasterTableView.ExportToPdf() crashes Adobe Reader

Hi,

When calling RadGrid.MasterTableView.ExportToPdf() the Adobe Reader browser addon for IE 8 crashes after a few seconds. It starts to display the data, then says it "stopped working". I have looked at a few threads talking about Ajaxified grids and this but can't get around the issue.

Any advice would be appreciated.

Thanks,

Putting RadEditor in ReadOnly mode via Client-Side Script?

I need to put the RadEditor into 'read-only' mode using client-side script, where both the Toolbars and the Content area are disabled, but are still viewable.

I've tried the following code in Javascript, but the Radeditor's content area is still editable.

document.body.editor.enableEditing =

false;
    document.body.editor.set_editable(false);
    document.body.editor.EnableContentArea = false;
    document.body.editor.get_ContentArea().contentEditable = 'false';

Suggestions?

radcombobox TextChanged event not firing when number of checked items is the same

I have a combobox and i have set up a Textchanged event for it. The event fires fine when i select a different number of items every time, ex: select 1 (A) checkbox, then select 2 (A & B) checkboxes, then select 1 (A) checkbox again, etc. When i keep selecting 2 items (different items every time) the event does not get fired, ex: select 2 checkboxes (A & B), select 2 checkboxes (B&C).

I was previously using the selectedindexchanged event but i was having the same problem.

These are the properties set up for the combobox:

ID="ComboBox" runat="server" CheckBoxes="True" EnableCheckAllItemsCheckBox="True"

DataTextField="DEPARTMENT" DataValueField="DEPARTMENT" Width="300px" MaxHeight="600px"

AutoPostBack="True"

Protected Sub ComboBox_TextChanged(ByVal sender As Object, ByVal e As EventArgs) Handles ComboBox.TextChanged

'do something

End Sub

Any suggestions on how to address this?
