I have a GridView that I'm binding to a custom collection of custom objects. In this GridView, I need to bind a ComboBoxColumn to a set of values in a different collection.

For example,

I've created a VB.NET List(of String) that holds the names of states. My class that the grid is bound to has a State property. I want to bind the states column to that List(of String) collection so that the user sees the dropdown of all available options when editing the particular record.

My List(Of String) is defined in a Module, and thus accessible as a global variable in the app. The custom class comes from a different library, and doesn't know anything about the list of states.

I can't seem to get the ItemsSource of the ComboBoxColumn to bind to something defined in a Module. Is such a scenario allowed?

Default Style problem

Hi

I've followed this FAQ which explains that to set the Default Style, we can declaratively add the properties in XAML and set "DocumentInheritsDefaultStyle" to true.

I've done this, and open my document and type some text - it's in Times New Roman size 11. If I add a table, all text added is in Times New Roman 11.

My problem is with tables. If I check the built in styles TableNormal and TableGrid, they're actually set to Verdana 12. Strange, then, that my table contains Times New Roman 11 text.

If I copy and paste the table somewhere else in the doument... all text changes to Verdana 12!

If anyone could explain:
- why copy and paste causes this change. Surely if a table is a certain style or has certain overriden local values, they should remain?
- the difference between "TableNormal" and "TableGrid", and why we can't delete either via the UI. And why, if I open a document without a TableGrid style, it creates one.

Bug in custom slots?

Hi, not sure if I found a bug:

When in the range of the slot indicates a busy year earlier, in my case proved 1753 (First year sql server). Schedule performance drops significantly.

Slot slot = this.CreateWorkingSlot(new DateTime(1753, 1, 1, 9, 0, 0), new DateTime(1753, 1, 1, 13, 0, 0), RecurrenceDays.Monday | RecurrenceDays.Tuesday | RecurrenceDays.Wednesday | RecurrenceDays.Thursday | RecurrenceDays.Tuesday);

I'm afraid you do a loop in reverse.

Sorry for my english and thanks,

Metro-Theme: Text is white on white

Hi!

When I use the Metro-Theme and place a RadGridView inside a RadTabItem the text inside the Grid becomes white on a white background. What is going wrong here? We are using 2011-Q2-SP1 controls.On the screenshot you can see that there IS some data inside the grid but it can't be seen.

DragDropManager doesn't drop on all control

I am using new DragDropManager and all works fine less then for a little problem that with previous version (RadDragDropManager) was working correctly :

Like attached picture , i have one user control composed by one Grid with one Image and one TextBox ; the usercontrol is marked with :

<UserControl x:Class="LibreriaWpfCoster.EditorSingolaVariabileInt32"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:globalization="clr-namespace:System.Globalization;assembly=mscorlib"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

MinWidth="40"

MinHeight="20"

mc:Ignorable="d"

d:DesignWidth="40"

d:DesignHeight="71"

Loaded="UserControl_Loaded"

>

<Grid x:Name="LayoutRoot"

Background="LightGreen"

AllowDrop="True"

>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="20"/>

<ColumnDefinition Width="*"/>

</Grid.ColumnDefinitions>

<Image x:Name="imgObj"

Source="Images/Numero32Negativo.png"

Stretch="Uniform"

MouseLeftButtonDown="imgObj_MouseLeftButtonDown"

/>

<TextBox x:Name="varObj"

Grid.Column="1"

Panel.ZIndex="0"

Text="{Binding Path=PlcVar, Mode=TwoWay}"

PreviewKeyDown="varObj_PreviewKeyDown"

ContextMenu="{x:Null}"

/>

<TextBox x:Name="varSysObj"

Grid.Column="1"

Panel.ZIndex="0"

Text="{Binding Path=SysVarName, Mode=TwoWay}"

PreviewKeyDown="varObj_PreviewKeyDown"

ContextMenu="{x:Null}"

/>

</Grid>

</UserControl>

AllowDrop is placed on the Grid , but placing on the entire Usercontrol doesn't change the problem.

The drop is allowed only on the Image of the control and not on the whoole usercontrol loke with previous version ....
I have try too setting AllowDrop on only one RadNumericUpDown and in this case the drop is allowed ONLY if i am with cursor over the up/down buttons

I have added two images to explain the problem.
Can you help me , because for my company is important to solve this problem.

Senseless replacement of RadMaskedTextBox

Hi,

Since we’ve encountered your new RadMaskedInput controls and realized, that these are the replacement of your RadMaskedTextBox (they are, aren’t they?), we didn’t find any reason for this update. Even worse, we are about to use your old RadMaskedTextBox on.

We mostly use your input controls for non-restricted text or non-restricted numeric values. In those cases we expect an input behavior like a normal TextBox got. More precisely, inputs a user enters shouldn’t replace old characters just because the mask restricts the length of the characters. The input, a user does should be just inserted at the caret’s position, without replacing.

The other problem, we’ve ran into is the following: We’ve bound a string value to the Value property of a RadMaskedTextInput control. This control has a mask of 20 optional alphanumeric characters (Mask=”a20”). Now when moving the caret at a different position then the beginning, the entered text would be saved without leading whitespaces. That’s a behavior which no user would expect.

Using your old input control, we didn’t run into all this trouble. I don’t think that there are many developers, who are used to your old Input Control, like the new ones. I don’t understand why you’ve replaced good working controls with these weak components.

I would recommend you to provide just one suite of input controls, which really work and which offers a way to be less restrictive.

Best,

Martin

PlotMode vs zoom

Hi,

is it a known bug when DateTimeContinuousAxis PlotMode is set to OnTicksPadded, when the chart is zoomed, the XAxis drifted depending on the zoom value? It works fine when PlotMode is set to OnTicks, but there's no padding with the chart border (that;s why I need OnTicksPadded).

Please see the latest picture.(the first picture, wpf_radchartview_plotmode_zoom_1.png,
doesn't show the problem clearly).

Which control - GridView or TreeListView

Hi

I am new to the telerik wpf controls and because I am am unsure of their capabilities, I don't know which one to select. I've been considering the radgridview in "hierachical mode" but now I'm not sure whether this is the correct control to use or perhaps the TreeListView.

My use case is as follows:
I have some hierarchical data as follows

Subject A Name Address DoB etc
HospitalVisit1 VisitDate SeenBy etc etc
Treatment1 Location Drug etc etc
Treatment2 Location Drug etc etc
Treatment3 Location Drug etc etc
HospitalVisit2 VisitDate SeenBy etc etc
Treatment1 Location Drug etc etc
Treatment2 Location Drug etc etc

Subject B Name Address DoB etc
HospitalVisit1 VisitDate SeenBy etc etc
Treatment1 Location Drug etc etc
Treatment2 Location Drug etc etc

I need to display the above. Then I going to provide the UI to flatten this data into 1 row per subject. To do this, I think I need to add a boolean columns to permit the user to choose which of the child events they want to use in the flattening mechanism. eg for Subject A

X Subject A Name Address DoB etc
HospitalVisit1 VisitDate SeenBy etc etc
Treatment1 Location Drug etc etc
Treatment2 Location Drug etc etc
Treatment3 Location Drug etc etc
X HospitalVisit2 VisitDate SeenBy etc etc
X Treatment1 Location Drug etc etc
Treatment2 Location Drug etc etc

The rows marked X will then be used to create a flat structure eg

Subject A Name Address DoB HospitalVisit2 VisitDate SeenBy Treatment1 Location Drug etc etc

I'd be grateful if someone could suggest which control would best suit my purposes. I'd assumed the radgridview or the treelistview but perhaps there may be other ways of doing this which may be better

Many thx

Simon
