DateTimePicker Focus

I have a windows form in my application which uses the datetime picker. I have noticed that there is no "Focus" property on the control. I cannot do the following:

fromDatePicker.Focus() and force my my user to interact with that control first, other Telerik controls on the form allow me to do this.

I am using the latest version of the WinForm controls and VS 2019

What am I missing?

Thanks

[Solved] Best Fit functionality

Hi,
I'm trying to use the best fit functionality for ListViews. Im using a list as the datasource like this:

radListView.DataSource = List<Myclass>

and in the BindingCompleted event i do the following:

            foreach (ListViewDetailColumn c in rlv.Columns)
            {
                c.AutoSizeMode = ListViewBestFitColumnMode.AllCells;
            }

The columns are not resized at all. Could you provide me with an example of how to use this feature ?

Completion window does not open on proper location

Hello,

I have problem with completion window location when vertical scroll of SyntaxEditor is not at start position. In that case position of completion window is at the top of control, in same case, somewhere else. I reproduced such behavior on minimal example which I am sharing with you right now.

using System.Windows.Forms;

using Telerik.WinForms.Controls.SyntaxEditor.UI.IntelliPrompt.Completion;

namespace WindowsFormsApp1

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

ICompletionInfoCollection completionInfoCollection = new CompletionInfoCollection

{

new CompletionInfo("AAA", "A description."),

new CompletionInfo("BBB", "B description."),

new CompletionInfo("CCC", "C description.")

};

var completionListWindow = this.radSyntaxEditor1.SyntaxEditorElement.IntelliPrompts.CompletionListWindow;

completionListWindow.Presenter.CompletionListItems = completionInfoCollection;

}

private void radSyntaxEditor1_DocumentContentChanged(object sender, Telerik.WinForms.SyntaxEditor.Core.Text.TextContentChangedEventArgs e)

{

Telerik.WinForms.Controls.SyntaxEditor.UI.CompletionListPopup completionListWindow = this.radSyntaxEditor1.SyntaxEditorElement.IntelliPrompts.CompletionListWindow;

completionListWindow.Show();

completionListWindow.Refresh();

}

As you can see in the images, in the first two cases everything is ok, but in the third image, when the vertical scroll is not at the start position (moved a little bit), the completion window has a completely wrong place.

Thank you for your answers.

Export Diagram Image

Is it possible to export the whole diagram as an image?

Image image = this.radDiagram1.ExportToImage(new Size(10000, 5000));

Clipboard.SetImage(image);

This only exports the visible area which gives me scrollbars which is not what I need. I want the entire diagram as an image.

Thanks

Changing border color of textbox and have it stay even when control is not in focus

Hello,

Already using back color of textbox for validation. I'm trying to set border color for a different flag on the same textbox, but this coloring goes back to default color when the control is not in focus using TextBoxElement.Border.ForeColor. Would like to have the backcolor stay all the time; which I could achieve with RootElement.BackColor, but this goes away when the control is in focus.

How can I achieve a static border color?

EnableHeaderCheckBox to check only enabled check boxes

My grid has a checkbox column "MyColumn" that has EnableHeaderCheckBox enabled. That column is disabled in the following manner using the CellFormatting event, code follows(did it this way due to need to show a tool tip). When I click on the header check box, every check box, including the disabled ones, are checked. I don't want those that are disabled to be checked. I've tried using the event HeaderCellToggleStateChanged to modify the toggle value of the checkbox, it's not taking effect. How can I do this?

private void MyGrid_CellFormatting(object sender, CellFormattingEventArgs e)
try
{

e.CellElement.RowElement.ToolTipText = @"";
e.CellElement.Enabled = true;

if (!(bool)e.Row.Cells["Condition1"].Value)
                {
                    e.CellElement.Enabled = false;
                    e.CellElement.RowElement.ToolTipText = @"Disabled condition 1 ";
                }

[Solved] Export to Vector

Is there a way to export diagram to a vector type image? I only see options to export to bitmap. Also, export only includes visible image, anything that was generated outside of initial view (such as negative positions) are not rendered.
