Hi, i'm trying to make application similar to ms.visio. I'm using RadDocking and make two RadPaneGroup in leftside and rightside. the leftside is for the list of drag&drop elements like shape,image or anything. the rightside is for the layout and i can save the layout.

the leftside is like an icon with text and when we drag it, it will show the original image/shape.

what is the best way to do that? is using RadDocking good enough? any specific controls or feature that can be used?

Thanks,

Mirza

Visual Studio 2013 Dark Theme and ContextMenu

I am using the Visual Studio 2013 Dark Theme (using Implicit styles) and for the most part everything looks great out of the box. One issue that I have run across is that the Context Menu that shows up for a TextBox (Cut, Copy, Paste) is not themed at all. Additionally, using the RadRibbonWindow, when clicking on the Icon, the Context Menu that shows up (Restore, Move, Size, Minimize, Maximize, Close) is not themed at all. I have to think that I am missing a setting somewhere for these to be themed but I cannot find it anywhere.

Can you help me out?

[Solved] Formula Cell Text Alignment Wrong After Value Update

Hi,

When the value in a cell containing a formula gets updated the text alignment is incorrect. See cell D2 in attachment after I put a 1 in cell B2. There is plenty of room for the value to be displayed correctly. The formula in D2 is =B2*C2.

I have tested this on the Telerik demos and can get the same thing to happen on there so it has nothing to do with my code.

This makes this control very unusable and I have customers complaining about this.

Thanks

Anthony

Set width of AutoGeneratedColumns

Hello everyone,

We created a Custom Control which has a GridView as a part of it. We use the AutoGeneratingColumns functionality and the DisplayAttribute to define the header text. That works perfect. We want to set the Columns to a fixed width, and it would be great to do this with an Attribute or some sort of other way.

Does anyone have a suggestion? We don't want to change the fact that the columns are auto generated.

Thanks for any help...

Use seconds on Duration on Recurrence Window

I need to add values to the dropdown list of Duration so that they are 10 seconds, 20 seconds, 45 seconds, etc. So I am able to add them okay to the list:

var durationPicker = sender as DurationPicker;
durationPicker.Items.Add("5 seconds");
durationPicker.Items.Add("10 seconds");
durationPicker.Items.Add("0.5 minutes");
durationPicker.Items.Add("2 minutes");
durationPicker.Items.Add("7 minutes");

However, picking any seconds doesn't update the End Time like if I picked 2 minutes. It seems to ignore anything that is seconds. Could you show me how to make seconds increments work on the Duration so it effects the End Date? We often schedule items every 60 seconds. Or 30.

RadRibbonTab not Disconnecting Items on Binding

I believe I have found a bug relating to how the RadRibbonTab handles things when its ItemsSource is set.

Please see the attached demo app.

Am I doing something wrong? If so, please advise.

Path=Value,

Mode=TwoWay,

UpdateSourceTrigger=PropertyChanged}"

ScaleMode="FitToWidth"

ScrollViewer.VerticalScrollBarVisibility="Auto" />
