I've noticed in the Auto Complete Box if you type a selection (or paste) and then left mouse click off the control the Selected Item will not be populated.

If I type (or paste) a selection and hit the "tab" key it will select the item.

How can I select the item when the user left mouse clicks off the control?

I can easily duplicate this with the "Auto Complete Box | First Look" from the WPF Controls Example.

See the attached pics.

The first example I typed "Respect" into the autocomplete box for Best Music Hit.  I hit the Tab button and the data populated.

The second example I typed "Respect" into the autocomplete box for Best Music Hit.  I then left mouse clicked outside of that control and the data does not populate.

Please advise.

Hi,

on the Telerik website the following documentation can be found about Column Groups:

(figure 5 is not included here since it was not necessary)

I don't want the RadGridView to duplicate the column group once the FrozenColumnSplitter has been moved to the first column.
In my case I only have one column group, and I don't want it duplicated if the Frozen Column splitter is moved:

Do you know how I can change this?
Thanks!

Hi

I want to ask if there is any option to make QueryableEntityCoreCollectionView perform in backgroud with showing some loading icon on grid, cause it has slow performance for loading large DB table?

UI is not responding while loading. With pagging it is better, but we whould like to not use pagging. I was testing QueryableEntityCoreCollectionView on MVVM example: https://docs.telerik.com/devtools/wpf/controls/radentityframeworkcoredatasource/entityframeworkcore-mvvm-usage

Thanks

Can I link between Connection and Connection?

If it possible, tell me please,,,

hello.

I used the scroll synchronization function in two gridviews through the linked example.
https://www.telerik.com/forums/scrolling-two-grids-f949e02b84ab

Since this is an old version, the ShowSearchPanel property does not exist.

If I put a SearchPanel in "PART_VerticalScrollBar", two objects appear.

When SearchPanel=true, the first is the VerticalScrollBar of SearchPanel, and the second is the VerticalScrollBar of the GridView.

When SearchPanel=false, only VerticalScrollBar of GridView is displayed.

How can I identify the "PART_VerticalScrollBar" of the GridView when the user uses the SearchPanel as a variable? I guess you shouldn't use "LastOrDefault".

Thanks.

Hi,

I'm trying to toggle the visibility of my columns based on the input of the search panel. My goal is to achieve something similar to this.

So I have created a very simple behavior like this:

internal class SearchColumnsByNameBehavior : Behavior<RadGridView>
{
    protected override void OnAttached()
    {
        base.OnAttached();

        AssociatedObject.ShowSearchPanel = true;
        AssociatedObject.Searching += OnSearching;
    }

    protected override void OnDetaching()
    {
        AssociatedObject.Searching -= OnSearching;

        base.OnDetaching();
    }

    private void OnSearching(object sender, GridViewSearchingEventArgs args)
    {
        foreach (GridViewColumn column in AssociatedObject.Columns)
        {
            string columnHeader = column.Header?.ToString();

            if (!string.IsNullOrEmpty(columnHeader))
            {
                column.IsVisible = columnHeader.Contains(args.SearchText);
            }
        }
    }
}

Unfortunately, when typing text in the textbox of the search panel, I get the following exception:

'No coercion operator is defined between types 'System.String' and 'MyProject.SomeClass+MyEnum'

Where 'MyEnum' is  of type:

[Flags] enum MyEnum : ulong

Looks like there are things done under the hood of the search panel that I don't know about, or is it the '+' that is actually the real problem here?

What am I supposed to do? Thanks in advance!

Full stacktrace:

Hello, I have a RadRibbonGroup with content that I want to fill all available space in the group.

The content is intended to be more advanced, but in its most simple form it can be demonstrated with a textbox like this:

<telerik:RadRibbonGroup Header="My group" Width="200" Height="100">
    <TextBox av:Text="Some text"/>
</telerik:RadRibbonGroup>

The size of the RadRibbonGroup is set dynamically but in the example is locked to a static size. In this case I want the content of the group (the textbox) to stretch in all directions. Vertically this works works as expected and the textbox is stretched by default and can be set to top, bottom, etc. with the VerticalAlignment property. However, everything i do horizontally seems to be ignored.

The attached image demonstrates how the code above looks and what I want it to do. How do I make this work?
