I was expecting that calling AddNodeByPath would automatically create the necessary parent nodes similar to how Directory.Create() works.

treeView.AddNodeByPath("General\\Billing\\February\\Report.txt")

treeView.AddNodeByPath("General\\Billing\\March\\Report.txt")

treeView.AddNodeByPath("General\\Billing\\April\\Report.txt")

However, it just seems to add them all to the closest node it could find (if there are no nodes, then a bunch of "Report.txt" will be in the root node).

I have come up with the following to solve this issue, but I'm wondering if there's an easier way?

private RadTreeNodeCollection AddNode(string path)

{

if (path == String.Empty)

return treeView.Nodes;

string node = Path.GetFileName(path);

RadTreeNodeCollection parent = AddNode(Path.GetDirectoryName(path));

if (parent.Contains(node))

return parent[node].Nodes;

else

return parent.Add(node).Nodes;

}

Is this a bug, or is it documented somewhere that AddNodeByPath() doesn't create the necessary parent nodes?

User interaction with the gridView

Hi,

I am using the hierarchical Gridview as some sort of navigation tree.
Typically, the Grid is positioned on the left pane, the right pane contains detail data an more.

When the user selects a row, from any level in the grid, extra data is loaded and displayed on the right pane.
Mostly, the detail pane contains a lot more data, than is displayed in the navigation grid. Depending on the network speed, this can take a bit of time.

My problem is that the grid, used as a data navigation aid, still accepts user interaction while detail data is being retrieved from the database.

Now I have to options:
1. fetch detail data in a separate thread, and abort when the user selects another row.
2. keep the grid (navigation aid) from processing user interaction while detail data is loading.

My question is,
can user interaction with the grid be placed on the same thread, so that it has to wait for the detail data being loaded?

Thanks.

Detect day on drag/drop from RadGridView

Greetings.

I'm experimenting with the latest demo version and running into an issue. Mind you, this seems like an edge case based on what I've read from others, but hopefully you can guide me.

I have an unbound RadGridView. It's unbound because I need to support drag/drop resorting within itself, simple inline editing and drag/drop to a RadCalendar. All of this is functioning well (I made extensive use of various how-tos on drag/drop from RadGridViews).

However, when I drag a row from the RadGridView to the RadCalendar, I'm unable to detect what day I've dragged the row onto. This would be trivial if I were using the drag/drop events of the Calendar itself, but I'm not. I'm using the Drag/Drop services I've declared as part of my extended RadGridView (similar to the documentation here: http://blogs.telerik.com/winformsteam/posts/13-05-15/extending-radgridview-to-enable-row-drag-and-drop-functionality )

My drop event looks like this...

private void dragDropService_PreviewDragDrop(object sender, RadDropEventArgs e)

{

Console.WriteLine(e.HitTarget);

var el = e.HitTarget as RadCalendarElement;

if (el != null)

{

GridDataRowElement draggedRow = ((SnapshotDragItem)e.DragInstance).Item as GridDataRowElement;

if (draggedRow != null)

{

int TaskID = (int)draggedRow.Data.Cells["TaskID"].Value;

// determine the date we dragged to, and update the task.

return;

}

How can I figure out which day I dropped the row onto? I don't seem to be able to get anything out of RadCalendarElement, nor can I find a relevant CalendarCellElement. Help! :)

Thanks,
Elsa

Deactivate Shortcuts

Hey,

For my current application security of viewed PDF files is the major aspect.

I added the following settings with PdfSharp

            securitySettings.PermitAccessibilityExtractContent = false;
            securitySettings.PermitAnnotations = false;
            securitySettings.PermitAssembleDocument = false;
            securitySettings.PermitExtractContent = false;
            securitySettings.PermitFormsFill = false;
            securitySettings.PermitFullQualityPrint = false;
            securitySettings.PermitModifyDocument = false;
            securitySettings.PermitPrint = false;

It seems that the Telerik Component does not recognize these settings.

So is it possible to deactivate the strg+a (select all) / strg+c (copy) shortcuts

Buttons for Printing and Select Text are already deactivated.

Thanks

Matthias

Copy drops TABLE/TR tags when first/last column are hidden

I am trying to copy and paste rows from my RadGridView to Excel. It works as expected when the first and last columns are visible, but if the first column is hidden the opening TABLE/TR tags in the HTML format on the clipboard are lost, and if the last column is hidden the matching closing tags are lost.

Repro: (VS2012, RadGridView Q1 2014)
Add a datasource with three columns. Right click on row header -> Copy, Paste into Excel.
Expected: The data spans three columns.
Actual: The data spans three columns. Yay!
Clipboard contents:

Version:1.0

StartHTML:00000097

EndHTML:00000239

StartFragment:00000133

EndFragment:00000203

<HTML>

<BODY>

<TABLE><TR><TD>3</TD><TD>Tools</TD><TD>Electronics</TD></TR></TABLE>

</BODY>

</HTML>

Hide the first column. Right click on row header -> Copy, Paste into Excel.
Expected: The data spans two columns.
Actual: All data is in a single cell.
Clipboard contents: No <TABLE><TR>.

Version:1.0

StartHTML:00000097

EndHTML:00000216

StartFragment:00000133

EndFragment:00000180

<HTML>

<BODY>

<TD>Books</TD><TD>Chocolate</TD></TR></TABLE>

Microsoft Office Add-in's

Hello all....

I have a quick question. I'm developing an add-in for MS Project. The add-in will essentially be a pop up Windows form but it must contain a line graph which will be rendered from values in an array.

Can the Telerik Winforms controls be used on forms which are contained in an MS Office add-in?

Many thanks,

Sacha

Change PageCollections background color

When adding a RadWizard to a form and setting a theme to a dark theme, each page's background color gets set to 'White".

I can change this manually as long as you dont set a theme, if you set a theme at run time it makes the pages back ground color white again.
Is there a way to change default back ground color ? I feel these controls should be set to transparent or at lest the forms color and not "White" specially when using a theme.

I mean I can run a for loop and iterate through the page collections and set the background but I hope there is a better way.

Gridview SelfReference Hierarchy Filtering

Hi,I have implemented a mixed mode hierarchy in my grid similar to this example
http://blogs.telerik.com/blogs/posts/11-03-07/re_mixed_hierarchy_mode_in_radgridview_for_winforms.aspx
Is it possible to assign a defaultivew of my "Folders" datatable as the source for my grid so that i can display only selected folders based on certain conditions.
I want to filter the defaultview of the table programatically so that the grid gets automaticaly updated.
The filtering option cannot be shown to the user.
