Custom Ruler Leaves Block at bottom of Scheduler

When I set the ruler to a shorter time period I get a strange block at the bottom of the scheduler.

This would not be an issue, if just for the fact that you can right click in this section and add an appointment?

This should be hidden or removed or not have the context menu show

Any help would be appreaciated

[Solved] Drag Drop Reorder

I have a screen with a radgridview that is bound. I am looking for a way to allow the user to click a row drag to a new location in the grid and drop and then save the order back to the sql tables. I have a field in the table called PrintOrder that will contain the order that is displayed on the screen. I have read some of the post about how unbound it works and some of the work arounds for bound items. In the grid I allow the users to group, reorder columns, hide and show columns. Would it be better to load the grid unbound, or is there a way around the bound issue. I have seen the code with the PreviewDragDrop and set the e.Handled to true, but not sure how to drop the row in the location. I can get it to look like you can drag and drop but when droped nothing happens.

void TestingItemView_PreviewDragDrop(object sender, Telerik.WinControls.RadDropEventArgs e)

{

e.Handled = true;

}

after the handle how do I drop. I assume the besthing to do would be to loop throught the grid and update the table with the new order.

[Solved] Truly Transparent Shaped Form

I've already read this post: http://www.telerik.com/community/forums/winforms/forms-and-dialogs/transparent-background-for-rad-shapedform.aspx It is close, but not quite what I need.

How do we use a PNG file with tranparency to make a truly transparent form? Any time I try this, truly empty areas in the PNG work fine, but partially transparent areas (like shadows) are underlayed with the "transparent" color.

I've attached three images:
- Screenshot of the intended effect. (The welcome/splash screen from Visual Studio.)
- Screenshot of setting the shaped form control background and transparent color to blue with my transparent PNG as the background.
- The form background image I am using to test.

Any help you can offer is greatly appreciated.

Thanks,

- Brad

Basic C/R/U/D example with Entity Framework?

I'm trying to implement a basic CRUD form using the GridView. I am using EF to populate the grid. I need to set some default values and found this link which shows using the DefaultValuesNeeded event. When I attempt to use this I get a NullReferenceException.

I'm obviously missing something here, but I'm not sure what.

Are there any examples that show:

Binding to records retrieved from EF
Setting default values when adding new records
Where to hook in saving changes when a record is added/updated/deleted
Displaying validation errors

Here's my currently working code for viewing the records:

var context = new

FlockWatchEntities();

var forecast = context.ForecastMSTs.Where(i => i.Type ==

"F"

).OrderBy(i => i.chrDesc);

grdForecast.DataSource = forecast;

And this is what the code in the DefaultValuesNeeded event looks like:

private void grdForecast_DefaultValuesNeeded(object

sender, Telerik.WinControls.UI.GridViewRowEventArgs e)

{

       e.Row.Cells[

"dtmEntered"

].Value = DateTime.Now;

       e.Row.Cells[

"chrEnteredBy"

].Value = System.Security.Principal.WindowsIdentity.GetCurrent().Name;

}

[Solved] Richtextbox & Theme

Hello all,

I am trying to add a theme to a rich text box but only "reset" and "control default" are the presented options.
Actually what I'm trying to achieve is a border around the rich text box exactly the same as the text box,
which I thought the theme would allow in some cases.

I'm using Q3-2012 and have tried in both VS2010 and VS2012 - all with the same results.

Any solutions?

Thanks

Terry

Is it possible to make a column invisible in the conditional formatting dialog. We have some primary key fields which are hidden (IsVisible = False + IsVisibleInColumnChooser = False), but still i see the columns in the conditional formatting dialog.

Any ideas?

Control X Axis Position in Line Chart

Hello,

I am having difficulty figuring out how to set the x-position of line data points in a windows forms chart. I am trying to create a chart with multiple lines of data that do not all start from the beginning of the x-axis or have regularly spaced intervals between the data points. Pretty much I want to be able to set the x-y position of each data point like a scatter plot. I see a "scatter line chart" for asp.net which seems to do what I am looking for, but I can't seem to find anything similar for windows forms.
