I have a custom visual item class derived from RadListVisualItem. My custom visual item is being created in the CreatingVisualListItem event, but the "Padding" property is ignored. I've tried Margin, as well, but no luck. My class is below. What am I missing?

public class CustomVisualItem : RadListVisualItem
{
DockLayoutPanel mainContainer;
StackLayoutElement leftColumn;
StackLayoutElement rightColumn;
LightVisualElement titleElement;
LightVisualElement photoElement;

private ImagePrimitive image;
public ImagePrimitive Image
{
get
{
return this.image;
}
}

protected override Type ThemeEffectiveType
{
get
{
return typeof(RadListVisualItem);
}
}

protected override void CreateChildElements()
{
base.CreateChildElements();

mainContainer = new DockLayoutPanel();
leftColumn = new StackLayoutElement();
rightColumn = new StackLayoutElement();
photoElement = new LightVisualElement();
titleElement = new LightVisualElement();

this.Children.Add(mainContainer);
mainContainer.LastChildFill = true;

leftColumn.Orientation = Orientation.Vertical;
leftColumn.Children.Add(photoElement);
photoElement.DrawBorder = true;
photoElement.Shape = new CircleShape();
photoElement.BackColor = Color.Transparent;
photoElement.BackColor2 = Color.Transparent;
photoElement.BackColor3 = Color.Transparent;
photoElement.BackColor4 = Color.Transparent;
photoElement.AutoSize = false;

rightColumn.Orientation = Orientation.Vertical;
rightColumn.Children.Add(titleElement);
titleElement.Padding = new Padding(50);
titleElement.AutoSize = false;
titleElement.DrawBorder = true;
titleElement.BorderBoxStyle = Telerik.WinControls.BorderBoxStyle.FourBorders;
titleElement.BorderLeftWidth = 0;
titleElement.BorderTopWidth = 1;
titleElement.BorderRightWidth = 0;
titleElement.BorderBottomWidth = 0;

mainContainer.Children.Add(leftColumn);
mainContainer.Children.Add(rightColumn);
DockLayoutPanel.SetDock(leftColumn, Telerik.WinControls.Layouts.Dock.Left);
DockLayoutPanel.SetDock(rightColumn, Telerik.WinControls.Layouts.Dock.Right);
leftColumn.NotifyParentOnMouseInput = true;
rightColumn.NotifyParentOnMouseInput = true;
titleElement.NotifyParentOnMouseInput = true;
photoElement.NotifyParentOnMouseInput = true;
}
}

Spreadsheet Control select a user's active cell/column

I am having trouble just trying to get a user's currently selected cell when using this control.

https://docs.telerik.com/devtools/winforms/controls/spreadsheet/features/ui-working-with-selection.html

from this page I can't even get this to work with my control (Selection seems to not be found so I Underlined and Bolded it)

Selection selection_2 = this.radSpreadsheet.SpreadsheetElement.ActiveWorksheetEditor.Selection;

selection_2.Select(new CellIndex(0, 0), false);

yes I have all the required References added to my project and form.

GridViewDecimalColumn String formatting problem for zeros (0)

Hi everyone!

I have a couple of columns containing numbers which some of them are zeros (0).I use the following code to format grid cells:

for(int i = 1; i < 6; i++)

{

GridViewDecimalColumn myCol = this.Grid.Columns[i] as GridViewDecimalColumn;

myCol.FormatString = "{0:###,###,###,###}";

}

As you can tell this code turns this value: 1234567 into this: 1,234,567

But my problem is that when this formatting is applied, since some of my cells contain the value "0", all of them will be blank and empty. It's like nothing exists in that cell but if I remove the formatting, all zeros are again where they should be.

I believe this problem is probably because of the type of "GridViewDecimalColumn" class.

What's your suggestion?

Separator in RadDropDownList

Hi. I want to add a separator (horizontal line) item to my radDropDownList. I've followed the approach at https://www.telerik.com/forums/adding-some-separator-in-the-list which works. However I have 2 items that have empty string as the text and I only want one of them to be shown as a horizontal line. I'm using a data bound list and I'd like to use either the item's value or it's tag to determine whether to show the item as a horizontal line or not. How do I get the item's value or it's tag from the VisualListItemFormatting event?

display tooltip on RadPanel

Hi there

I'm trying to show a tooltip on a RadPanel. Normally I'm using the ToolTipTextNeeded event for every Telerik control I used before. But this seem not to work here. I also tried the ToolTipText property on RadPanel.PanelElement. I also set AutoToolTip to true, without any success. What I tried:

1.private void panFiles_ToolTipTextNeeded(object sender, ToolTipTextNeededEventArgs e)

2.{

3. e.ToolTip.ToolTipTitle = "test1";

4.}

1.panFile1.ShowItemToolTips = true;

2.panFile1.PanelElement.AutoToolTip = true;

3.panFile1.PanelElement.ToolTipText = "test2";

1.panFile1.PanelElement.PanelFill.AutoToolTip = true;

2.panFile1.PanelElement.PanelFill.ToolTipText = "test";

However, the tooltip is still not showing up. I cannot find any information about it in the RadPanel documentation. Is this even possible for this control?

Best Regards,
Roman

Move Strip element to new row on resize

I am using the RadCommandBar, and for the strip elements I have the overflow visibility set to collapse, as I don't want the user to turn the command items off or hide them. When I resize, the Controls in the strip elements disappear and only a reduced-sized footprint of the right-most strip elements appear (see attached), with no ability to select the control contained within.

I think the best solution would be to automatically move these to a new row in the CommandBar as the size of the form is reduced, then move them back to the top row as form is expanded again. I assume I could do this in the form.resize event, checking the width of command bar, but i'm not sure all the nested properties I would need to manipulate to accomplish this.

Please let me know how to accomplish this, or if there is a setting I am missing that might achieve my described desired result. Basically, I'm looking for a solution that prevents the user from hiding the buttons or strip elements, but still provide access to the buttons when the form is resized.

Thanks

RadGridView Printing Support (Without using Telerik Reporting) to Include Custom Header and Footer

Hi,

May I know whether it is possible to customize the printouts Header and Footer in the Print Preview and actual report?

I'm trying to print directly from the RadGridView as I have nicely formatted the look and feel, and I need to print exactly what I've formatted to display on screen, with my Header and Footer, for example Header could be Company Name and Report Title, while the footer would be company address and contact numbers.

Please kindly advise me accordingly.

Thank you!

Cheers,
Jenson

How do I create a hierarchary on a column instead of a data row in a GridView

The data source for my main GridView object is a list of a custom object, which in turn contains child objects, and I want to be able to create a hierarchy grid that allows the user to drill into these child objects. I understand how to create the hierarchy if the entire row is a child record, but not how to accomplish this when a cell is the child record.

Example of my custom object is below.

public class Claim

{

public Claim();

//

// Summary:

// Provider billing for services

public Provider BillingProvider { get; set; }

//

// Summary:

// Claimant

public Claimant Claimant { get; set; }

//

// Summary:

// Claim number

public string ClaimNumber { get; set; }

//

// Summary:

// Member

public Member Member { get; set; }

//

// Summary:

// Policy

public Policy Policy { get; set; }

//

// Summary:

// Process date

public DateTime ProcessDate { get; set; }

//

// Summary:

// Date claim was received

public DateTime ReceiveDate { get; set; }

//

// Summary:

// Provider rendering services

public Provider RenderingProvider { get; set; }

//

// Summary:

// List of services provided

public List<Service> ServiceList { get; set; }

//

// Summary:

// Address where services were provided

public Address ServiceLocation { get; set; }

//

// Summary:

// Worksheet / bill number

public int Worksheet { get; set; }

}

//

// Summary:

// Member

public class Member : Person

{

public Member();

//

// Summary:

// Effective date

public DateTime EffectiveDate { get; set; }

//

// Summary:

// Member ID

public string MemberId { get; set; }

//

// Summary:

// Member's coverage policy

public Policy Policy { get; set; }

//

// Summary:

// Termination date

public DateTime TerminationDate { get; set; }

}

//

// Summary:

// Person

public class Person

{

public Person();

//

// Summary:

// Contact address

public Address Address { get; set; }

//

// Summary:

// Date of birth

public DateTime Dob { get; set; }

//

// Summary:

// First name

public string FirstName { get; set; }

//

// Summary:

// Gender

public string Gender { get; set; }

//

// Summary:

// Last name

public string LastName { get; set; }

//

// Summary:

// Middle name

public string MiddleName { get; set; }

//

// Summary:

// Social security number

public string Ssn { get; set; }

}

Looping through controls

The below code works in a Tererik report

                    Me.txt001.Value = drw("int001")
                    Me.txt002.Value = drw("int002")
                    Me.txt003.Value = drw("int003")

where drw is a DataRow

I have around 600 controls on a report and need to be able to loop through the various textboxes.

The following works in a Visual Studio Form but not in a Telerik report

                    For intCounter As Integer = 1 To 3
                        Me.Controls("txt00" & CStr(intCounter)).Text = drw("int00" & CStr(intCounter)).ToString
                    Next

It does not like Me.Controls("txt00" & CStr(intCounter)).Text

Any ideas, otherwise I would have to painstakingly refer to all controls by name.

Thanks.
