Hello,

I am using a RadAutoCompleteBox with multiselecting. 

I would like a user to be able to open the dropdown by clicking on the AutoCompleteBox and to be able to select all needed items in one go.

In general it should have the same behaviour like the StaysOpenOnEdit property of the RadComboBox.

Thanks in advance

Regards,

Kai

Hello,

I want to use multiselection in a RadCombobox. Is there a way to get the same layout for the Elements as in the AutoCompleteBox?

Best Regards,

Hi Team,

I have the following queries.

1. How to show the gridlines in the GanttView. (see the attached screenshot)

2. How to hide the border line between 2 columns. (see the attached screenshot)

3. How to reduce the MajorTickLine width. I have tried the below.
Here we are showing Days, week, month wise details.

Working Criteria:

Days - 45 to 79 

Week - 80 to 120 

 If the range of days increased more than 79, it will automatically display the week.

Not working while adjusting the range (customized range) for days and week. 

Please help us to sort it out.

Hi Team,

We need to display the multiple different property values in a same column definition. Bind each property in seperate textblock and also have to show the tooltip with respective details. Please refer the attached screenshot, which we are looking for it.

Please help us to sort.

Thanks,

Sabari.

Hello! I am learning an RadDocking example from Telerik Wpf Demo. When I try to unpin (hide) a RadPane I see an System.NullReferenceException. What's the problem?

Here's the code.

I think to create a contact form created from five different HTML webpages:

Four HTML webpages would prompt the user for various kinds of data and the fifth webpage would include a submit button and a success message in case a submit process went well form JavaScript’s side at least — not involving possible problems in the backend (PHP) routing.

My problem is that I don’t know almost anything about Ajax:
Ajax CRUD operation codes always seemed to me very long and complicated; perhaps since EcmaScript 2021 Ajax CRUD operations could be much simpler.

I seek some guidance about how to generally do this, how to save data prompted from the user in each of the four HTML documents) and so forth.

I'm using RadGridView quite a lot. One of the major functionality is column sorting.

This is radGridView definition. RadGridStyle contains set properties as follows:

    <Style x:Key="RadGridStyle" 
           TargetType="{x:Type telerik:RadGridView}">
        <Setter Property="ItemsSource" 
                Value="{Binding Elements}" />
        <Setter Property="AutoGenerateColumns" 
                Value="False" />
        <Setter Property="EnableRowVirtualization" 
                Value="True" />
        <Setter Property="EnableColumnVirtualization" 
                Value="True" />
        <Setter Property="FrozenColumnCount" 
                Value="5" />
        <Setter Property="ClipboardCopyMode"
                Value="All"/>
        <Setter Property="SelectedItem" 
                Value="{Binding SelectedElement}"/>
        <Setter Property="SelectionUnit" 
                Value="FullRow"/>
        <Setter Property="SelectionMode" 
                Value="Extended"/>
        <Setter Property="MinColumnWidth" 
                Value="75"/>

                </telerik:GridViewDataColumn>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

RadGridView can use column sorting only for columns no 1-5. Other columns have no ability to sort. There are no sort indicators on column header for each column. When I'm trying to add DataType or SortMemberPath for each column, inidicator appears, but clicking on indicator has no effect. Filter popup contains just only 0 or [null] value

This is definition of model, that I'm binding to radGridView. The collection ItemsSource is of type <IEquipment>.

public class Equipment : IEquipment
    {
        public int Index { get; set; }

        public string Name { get; set; }

        public string Code { get; set; }

        public string Description { get; set; }

        public string Group { get; set; }

        public IData Data { get; }
    }

public class Busbar : IData, 
    {
        public Voltage NominalVoltage { get; set; }
        public Voltage SwitchgearRatedVoltage { get; set; }
        public string SwitchgearType { get; set; }
        public Current RatedCurrent { get; set; }
    }

I'm afraid that there are some problems with nested objects binding, because whem I'm trying to bind flatten definition of these two types (Equipment and Busbar), there are no problems.

Thank you for your help!

I'm using a RadNavigationView in my application that has an existing theme applied - I want to keep this theme rather than use the Telerik themes.  I've been able to manually style most of the control to match the existing theme, with the exception of the mouse over and selected item color. No matter what I try, it is always the default orange color.

Is there any guidance about that shows an example of how to take a standard RadNavigationView, and adjust the highlight colors of the RadNavigationViewItem?

Thanks in advance!
