It appears that only the first visible day on my timeline view is being constrained to my 6am to 6pm. The other days always show midnight to midnight. Bug?

Hi,

In my WPF MVVM application I have a view with RadTabControl with 4 different TabItems.
I use the tabs to display 4 different categories of items

Visibility Property of each TabItem is bound to a property in my ViewModel.

Now if let say Tab1 and Tab4 are visible and Tab2 and Tab3 hidden I got gaps like this:

[ Tab 1 ] __________________ [ Tab 4] .

How to make  all tab headers to move to the left like this:

[ Tab 1 ] [ Tab 4] __________________  .


(see pseudo-code below)

Dear all,
Recently I use radgridview and gridViewComboBoxColumn to achieve the goal that users could be insert or update database by dropping down the combobox. How can I get the selected-value to operate the database? My codes are listed as below. May you give me some hints? Thank you.

XAML Code:

<telerik:RadGridView x:Name="gv1"

                             Grid.Row="1"

                             Margin="5"

                             AlternationCount="2"

                             AutoGenerateColumns="False"

                             FontSize="{Binding Source={x:Static local:MySettings.Default},

                                                Path=FontSize,

                                                Mode=OneWay}"

                             IsFilteringAllowed="False"

                             SelectionUnit="FullRow"

                             ShowGroupPanel="False"

                             VirtualizingStackPanel.IsVirtualizing="True"

                             VirtualizingStackPanel.VirtualizationMode="Recycling">

            <telerik:RadGridView.Columns>

                <telerik:GridViewDataColumn DataMemberBinding="{Binding opc_id}"

                                            Header="opc_id"

                                            IsReadOnly="False" />

                <telerik:GridViewDataColumn DataMemberBinding="{Binding ip_address}"

                                            Header="ip_address"

                                            IsReadOnly="False" />

                <telerik:GridViewDataColumn DataMemberBinding="{Binding hmi_user}"

                                            Header="hmi_user"

                                            IsReadOnly="False" />

                <telerik:GridViewDataColumn DataMemberBinding="{Binding description}"

                                            Header="description"

                                            IsReadOnly="False" />

 

                <telerik:GridViewComboBoxColumn DataMemberBinding="{Binding entry_area}"

                                                DisplayMemberPath="description"

                                                Header="entry_area"

                                                IsReadOnly="False"

                                                SelectedValueMemberPath="Id"

                                                UniqueName="entry_area" />

 

            </telerik:RadGridView.Columns>

        </telerik:RadGridView>"

 

 

VB.NET CODE:

 

Private Sub gv1_RowEditEnded(sender As Object, e As Telerik.Windows.Controls.GridViewRowEditEndedEventArgs) Handles gv1.RowEditEnded

        If e.EditAction = GridViewEditAction.Cancel Then

            Exit Sub

        End If

 

        If e.EditOperationType = GridViewEditOperationType.Insert Then

            'Add the new entry to the data base.

 

            Dim opc As New OPC_Profile With {.opc_id = TryCast(e.Row.Cells(0).Content, TextBlock).Text, _

                                 .ip_address = TryCast(e.Row.Cells(1).Content, TextBlock).Text, _

                                 .hmi_user = TryCast(e.Row.Cells(2).Content, TextBlock).Text, _

                                 .description = TryCast(e.Row.Cells(3).Content, TextBlock).Text, _

                                 .entry_area = TryCast(e.Row.Cells(4).Content, LookupElement).ComboBox.Text}

        End If

Hi,

I would like to bind the visibility property of an annotaiton to a property of my DataContext binded to a checkbox.
It seems that setting the Visibility property of an annotation has no effects.
Is it a bug ? Do i need to remove it from annotation's collection and reinsert it ?

Regards.

I've created a DropDownButton which has a sequence of checkboxes and a ok/cancel button pair in the dropdowncontent. The dropdowncontent is not supposed to close unless I click one of the buttons, hit escape, return or click outside the dropdowncontent.

However, the dropdowncontent closes whenever I click the background on the dropdowncontent - which I do occationally because checkboxes are small and hard to hit when in a hurry.

How do I prevent the DropDownContent from disappearing when I click it's background (that is, the grid which holds the entire thing)?

Thanks!

Hello.

I have some custom control (inherits from Control class) and I need to style it as RadWindow (It's need for Mdi window in canvas control). How can I style the control? And how can I save changing theme function on it? Maybe I can use telerik brushes?

Thanks.

I am using version 2012.1.326.35.

I have a RadGridView with a DataTable dt as ItemsSource. The RadGridView appears to render the initial column specification correctly and also recognize the row changes. However, when I update the columns, then I notice that addition and removal of columns are not recognized in the RadGridView.

This is how I refresh my DataTable:

================================================
public void updateData(SomeCustomDataSource data)
dt.Clear();
int num_cols = model.Columns.Length;
for (int i = 0; i < num_cols; i++)
{
SomeCustomColumn c = data.Columns[i];
if (!dt.Columns.Contains(.Name)) // Adding columns not previously existing
{
DataColumn col = CreateDataColumn(c);
dt.Columns.Add(col);
}
}
dt.AcceptChanges();
RefreshGrid(); // Plain old OnPropertyChanged("DataSource");
================================================
I'd like to note that this is just some dummy code. In the actual code I wanted to use, I called dt.Columns.Clear() and re-added every single column on data update. And what happens in that case is that none of the columns changed but when I click on the "click to add new row" row insertion thing, I get a "[Column] does not belong to Table [Table]" ArgumentException, which implies the internal data is not actually refreshed in the RadGridView even though the rows are updated correctly.

Again, if you want my license key in order to provide support, I'd be happy to provide it.

Hello,

we are using Telerik WPF Controls Version Q2 2011 0920.

We have a scenario where we want to programmatically move TileViewItems from one TileView to another. This is done by removing the item from the RadTileView.Items Collection and adding it to the other in code behind.
The issue is that the header is disappearing if we do that (plain text defined in XAML with HEADER Property) and is doesn't come back if we move the TileViewItem back to the original TileView.

Update: Header-Property is correct after the move but the UI isn't showing anything.

Thanks,

Thomas
