Can't see the Resources of Appointments in RadScheduler

Hello,

I'm working on a project where I use the RadScheduler with the Timeline View.
I've already added the Appointments and the Resources, but it displays only the Appointments.

The whole thing is going to be a "holiday" planer. So on the left side there are all the employees and on the right side their holidays in the calendar.

Basically there is only one ResourceType, "employee". For the ResourceName i simply use their employee number.

I have the Problem that I see the Appointments in the View, but I don't see the Resources.

On the Debug-Screenshot you can see that there is a Resource with the right Name and Type in each Appointment, so I guess the method works, but I can't see it in the view.

(I really do miss a very simple example Tutorial on the topic of assigning Resources to Appointments)

What am I doing wrong?

Thank you for your help.

Best regards

Different Style for Parent and Child rows in TreeListView

Hi,

I am using a TreeListView to display financial data (element with costs per month) with sub-totals as the parent rows. The data structure is thus homogenous and a good fit for the TreeListView. The binding and data work perfectly, but now I would like to refine the styling to show a greater contrast between parent and child (e.g. make sub-total rows bold). Is there an simple way to do this?

RadEntityFrameworkCoreDataSource and RadGridView

Hello,

I'm trying to set up a RadGridView to display a RadEntityFrameworkCoreDataSource source using code-behind (currently a requirement) and cannot get the grid to populate with any data. I can access the data by using LINQ just fine, and can populate the grid using a ToList() version of that data, but I believe that it's just a copy of the data, and cannot be modified and saved to the original context.

Here's an example of what I'm trying to do:

var options = new DbContextOptionsBuilder<Test_Context>();
options.UseSqlServer(ConnectionString);
using var testContext= new Test_Context(options.Options);

RadEntityFrameworkCoreDataSource source = new()
{
    Name = "coreDataSource",
    DbContext = testContext,
    QueryName = "TblCustomer"
};

// This doesn't populate the grid
rgvCustomers.ItemsSource = source.DataView;
                
// This populates the grid
var customerList = textContext.TblCustomer.Where(customer => customer.Id != -1).ToList();
rgvCustomers.ItemsSource = customerList ;

How do I get the RadEntityFrameworkCoreDataSource to query the data so that it can populate the grid?

Also, how would I go about only querying the customers with an Id != -1 using said Data Source? Is that as simple as setting the filters, then querying?

I'm new to this, so apologies if I've missed a simple step.

Bind multiple searching values in autocomplete box

<telerik:RadAutoCompleteBox TextSearchMode="Contains" SelectedItem="{Binding Entity, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" DisplayMemberPath="Name" HorizontalAlignment="Stretch" SelectionMode="Single" Margin="125,100,0,10" VerticalAlignment="Top" Width="Auto" Grid.Column="0" Name="customerACB" SearchTextChanged="customerACB_SearchTextChanged" AutoCompleteMode="Suggest" >
<telerik:RadAutoCompleteBox.DropDownItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Label Content="{Binding Code}" Width="70" />
<Label Content="{Binding Name}" Width="310" />
</StackPanel>
</DataTemplate>
</telerik:RadAutoCompleteBox.DropDownItemTemplate>
</telerik:RadAutoCompleteBox>

Currently, i am able to search using "Name". If I change displaymemberpath to code it will show the result if the search string match with "code"
I need to search using both values "Name" and "code".

RadGridView - ToolTip for Dynamically Created Column

I have a RadGridView that populates dynamically based on columns present in an Excel spread-sheet. I'm able to create the columns but not having luck getting the ToolTip to display.

Thanks in advance - Jon

Here is my code snippet:

foreach (DataColumn column in dt.Columns)
{
Telerik.Windows.Controls.GridViewDataColumn gridviewDataColumn = new Telerik.Windows.Controls.GridViewDataColumn
{
Header = column.ColumnName,
Name = column.ColumnName,
DataMemberBinding = new System.Windows.Data.Binding(column.ColumnName),
// Tooltip = ???
};

dtg_PreviewMapGrid.Columns.Add(gridviewDataColumn);
}
dtg_PreviewMapGrid.ItemsSource = dt;
