https://docs.telerik.com/devtools/winforms/controls/gridview/filtering/setting-filters-programmatically-(composite-descriptors)

When creating a composite filter descriptor with a value that contains an array of enums, it generates an expression with IN, and an exception is thrown when adding it to the FilterDescriptors on a RadGridView control.

 

Exception Message:

{"The expression contains undefined function call In()."}

 

The expression value is: ([RandomPropertyName] IN (1,3,9) OR [RandomPropertyName] = 10)

 

We have recently upgraded from 2015.2.728.40 (where this worked) to the Feb. 2019 version, then today upgraded to the May 2019 version. The issue remains.

 

The project includes the following Telerik references:

 

Telerik.WinControls

Telerik.WinControls.GridView

Telerik.WinControls.PdfViewer

Telerik.WinControls.RadDock

Telerik.WinControls.RadMarkupEditor

Telerik.WinControls.UI

Telerik.Windows.Documents.Core

Telerik.Windows.Documents.Fixed

Telerik.Windows.Zip

TelerikCommon

 

You can use the following code snippet and follow the steps from the provided gif file:

        public RadForm1()
        {
            InitializeComponent();

            DataTable dt = new DataTable();
            dt.Columns.Add("Id");
            for (int i = 0; i < 100; i++)
            {
                dt.Rows.Add(i);
            }

            this.radMultiColumnComboBox1.DisplayMember = "Id";
            this.radMultiColumnComboBox1.ValueMember = "Id";
            this.radMultiColumnComboBox1.DataSource = dt;
            this.radMultiColumnComboBox1.SelectedIndex = -1;

            this.radMultiColumnComboBox1.SelectedIndexChanged += radMultiColumnComboBox1_SelectedIndexChanged;
        }

        private void radMultiColumnComboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            RadMessageBox.Show("You just selected index " + this.radMultiColumnComboBox1.SelectedIndex);
        }

Workaround:

private void RadDropDownButton1_DropDownOpening(object sender, EventArgs e)
{
    var args = e as RadPopupOpeningEventArgs;
    var popupSize = radDropDownButton1.DropDownButtonElement.DropDownMenu.Size;
    var x = args.CustomLocation.X - (popupSize.Width - radDropDownButton1.Width);
    args.CustomLocation = new Point(x, args.CustomLocation.Y);
}

Use attached to reproduce.

- In the excel-like filter popup unselect 0.1, 0.2, and 0.3 and then click "Fork"

- When the layout is loaded the values are changed to 1, 2, and 3. 

Workaround:

Change the culture before saving/loading the layout. 

To reproduce:

- Open The popup

- Click on it, and then click on the form

- Repeat until the popup stays opened

Hello,

I have already used your ItemFormatting event in my code and implemented it the same way you have provided.

In my code, i have created 7-8 messages and fixed the first msg's timestamp to "6/6/2019 11:53:08 AM" and the remaining messages with timestamp of 2 minutes more than this time. Whenever the event is triggered i wrote a code which compares the timestamp of my message with this timestamp "6/6/2019 11:53:08 AM". Conditionally only the first message falls in this condition and i paint it red, which works well for first time (On load) and then when i scroll my chat, the event unnecessarily paints the remaining msgs too, which should not happen.

I am attaching my .cs file with designer please refer to it, and resolve this asap. Looking forward to your response.

Thanks.

Bind the grid to an enumeration, save/load the layout. 

The bug can be reproduced like this:

- Launch the "Demo Application - Telerik UI for WinForms R1 2019 SP1" provided with the control suite.

- Choose "Explore all controls", "List control", "Settings"

- In the "Settings panel", set "Selection Mode" to "MultiSimple"

- In the "Themes" panel, choose "Office2013Light"

- click on the second item, then the third, then the fourth to select --> OK

- click on the second item to unselect it --> Not OK, the list isn't refreshed accordingly

- click on the third item to unselect it --> Not OK, the second item is properly unselected but the third one is still selected

Steps to reproduce:

1) Add a RadForm with 3 buttons. Apply Fluent Theme to all.

2) In the click handler of the first two buttons, set enable to false for the button that was clicked. Third button, do nothing.

3) Run app. Click all 3 buttons.

 

Desired Result:

Focus indicator should be hidden for previous-focused but now-disabled controls.

 

Actual Result:

Blue Fluent focus-indicator border is still showing (my user's are confused and complaining), see attachment.

[May happen on other themes too, didn't check.]

 

Had to implement a work-around...

 

Work around: 

Set border element to off for every programmatically disabled control: this.radButton1.ButtonElement.BorderElement.Visibility = ElementVisibility.Hidden;

Please refer to the attached sample project and follow the steps illustrated in the gif file.

When developing a third party (PPM Hexagon Smart Sketch), focus on the grid and key-in. When using the winform basic control, there is no problem but when you create it with RadGridView, the application will be stopped by key-in.

The new series will be similar to the RadarColumnSeries which is already available. https://docs.telerik.com/devtools/aspnet-ajax/controls/htmlchart/chart-types/polar-chart

Use attached to reproduce. 

Type "Christoff" and scroll down.

Workaround:

public RadForm1()
{
    InitializeComponent();
    FilterToList.DropDownListElement.AutoCompleteSuggest.DropDownList.VisualItemFormatting += DropDownList_VisualItemFormatting;
}

private void DropDownList_VisualItemFormatting(object sender, Telerik.WinControls.UI.VisualItemFormattingEventArgs args)
{
    args.VisualItem.TextWrap = false;
}

 

ChildRowHeight can be set on the main table element of the control like this:

this.radGridView1.TableElement.ChildRowHeight = 750;

When the grid is in a hierarchy and a parent row is expanded, the inner child template will create a new table element and its ChildRowHeight is 205 which is the default value. It would be expected that the height of the inner table element is initially set as the height of the main table element of the control.

A possible workaround is to handle the ChildViewExpanded event of the grid this way:

private void RadGridView1_ChildViewExpanded(object sender, Telerik.WinControls.UI.ChildViewExpandedEventArgs e)
{
    GridTableElement tableElement = this.radGridView1.CurrentView as GridTableElement;
    if (tableElement != null && e.ParentRow.HierarchyLevel == 1)
    {
        tableElement.ChildRowHeight = 750;
        tableElement.InvalidateMeasure(true);
    }
}

 

 

Use attached to reproduce!

Run the app then drag the left side of the window to the right as far as possible, then rapidly drag the left side of the window back and forth. At some point, the application should crash with the exception (the project is available for download internally only)

- Add RadRibbonForm
- Set the radRibbonBar1 RightToLeft property to YES at design time
- Close the designer and open it again -> another ribbon is showing up

Workaround: done set the ribbon's RightToLeft property, just set the RightToLeft property of the form itself.

Use attached to reproduce.

Accelerator Key is working but not underlined (underline is enabled in windows 10 and visible in other applications).
