Hi

I'm with the trial version of Telerik for Winforms and I'd like to design the following layout:

I want to have a simple combobox at the left of the screen with some predefined options. At the right of the screen, I'll have a group of controls composed by a label, a textbox and a button. I want to have multiple groups but only one will be available to the user when he choose an option from the combobox.

I'm trying to use the LayoutControl, but I have a problem: I'm not able to have 2 or more controls under the same container (my idea is to make visible/not visible the containers to show the correct one). I tried to put a panel on the layout and, later, to create the controls inside it... but the controls are assigned automatically to a new layout item instead the panel I created.

How can I do this?

Thank's in advance

Set RadSpinEditor Selection Color

Is there a way to set the selection color for the RadSpinEditor like you can with a RadTextBoxControl? Or can I change the TextBox element into a TextBoxControl element and set it that way?

Thanks.

After I load the radPivotGrid with appropriate DataSources' binding, I need to find when the user has made a selection(i.e. once he releases the left mouse button) on the data displayed under it. I tried to use the MouseCapture event but was unable to access the selected info. in any way.

Kindly help.

INotifyPropertyChanged thread safe binding

Dear support,

i my application in use two classes who implements INotifyPropertyChanged to reflect the changes on them automaticly in gridview.

These is working quit nice, when using the gui thread.

my application is listening to multiple comports and starts adding new entry's from another thread to this classes.

INotifyPropertyChanged of courses raises an update for the gridview, so that the grid raises an exception because of the wrong thread

where must in place the invoke to make this call thread safe. in the form itself or on the gridview.

Thank you

visible by PageViewItemType.GroupHeaderItem

Hi,

I have RadPageView with a lot of items, which are organized by categories.

I'd like that when I click on a category title (PageViewItemType.GroupHeaderItem?) I display the pages which are related to this GroupHeaderItem.

Eg.

Organisation (GroupHeaderItem)

- Page1

- Page 2

Administration (GroupHeaderItem)

- Admin 1

- Admin 2

I don't see how to accomplish that with RadPageView.

I chose RadPageView over RadTreeView because the management of the forms that are shown are managed perfectly with RadPageView.

Thank you for your help.

RadGridView GridViewTemplate

Hey guys,

My issue is to show some field value (readonly) from parent object in child view template, so that the first comes parent's field value and below it goes detail rows as usual.

In my example I had to add unnecessary public List<string> Details { get; } = new List<string>(); property to make second tab.

Is it possible to add some control to GridViewTemplate without using multiple child views?

Prepared example:

public sealed class Student

{

public int Id { get; set; }

public string FirstName { get; set; }

public string LastName { get; set; }

public string AdditionalInfo { get; set; }

public List<Award> Awards { get; } = new List<Award>();

public List<string> Details { get; } = new List<string>();

public static List<Student> GenerateList()

{

var students = new List<Student>();

for (int studentIndex = 1; studentIndex <= 5; studentIndex++)

{

var student = new Student()

{

Id = studentIndex,

FirstName = $"FirstName {studentIndex}",

LastName = $"LastName {studentIndex}",

AdditionalInfo = $"blah blah blah.... {studentIndex}"

};

for (int awardIndex = 1; awardIndex <= 5; awardIndex++)

{

var award = new Award()

{

FundName = $"FundName {awardIndex}",

Amount = studentIndex * 100 + awardIndex,

};

student.Awards.Add(award);

}

student.Details.Add($"unused text {studentIndex}");

students.Add(student);

}

return students;

}

public sealed class Award

{

public string FundName { get; set; }

public double Amount { get; set; }

}

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

radGridView1.ReadOnly = true;

radGridView1.Columns.Add(new GridViewTextBoxColumn("FirstName"));

radGridView1.Columns.Add(new GridViewTextBoxColumn("LastName"));

GridViewTemplate childTemplate2 = CreateChildTemplate2();

GridViewRelation relation2 = new GridViewRelation(this.radGridView1.MasterTemplate, childTemplate2);

relation2.ChildColumnNames.Add("Details");

this.radGridView1.Relations.Add(relation2);

GridViewTemplate childTemplate1 = CreateChildTemplate1();

GridViewRelation relation = new GridViewRelation(this.radGridView1.MasterTemplate, childTemplate1);

relation.ChildColumnNames.Add("Awards");

this.radGridView1.Relations.Add(relation);

this.radGridView1.DataSource = Student.GenerateList();

radGridView1.AutoGenerateColumns = false;

radGridView1.CellFormatting += RadGridView1_CellFormatting;

this.radGridView1.TableElement.PageViewMode = PageViewMode.ExplorerBar;

var aa = this.radGridView1.TableElement.PageViewProvider;

}

private void RadGridView1_CellFormatting(object sender, CellFormattingEventArgs e)

{

GridViewDataColumn column = e.CellElement.ColumnInfo as GridViewDataColumn;

if (column != null && column.OwnerTemplate.Caption == "aa")

{

e.CellElement.TableElement.Visibility = Telerik.WinControls.ElementVisibility.Hidden;

RadPageViewContentAreaElement content = e.CellElement.TableElement.Parent as RadPageViewContentAreaElement;

RadLabelElement radLabelElement = new RadLabelElement();

if (content.FindDescendant<RadLabelElement>() == null)

{

content.Children.Add(radLabelElement);

var row = (GridViewHierarchyRowInfo)e.CellElement.RowInfo.Parent;                         

                           var student = (Student)row.DataBoundItem;

                           radLabelElement.Text = student.AdditionalInfo;

}

else

{

e.CellElement.TableElement.Visibility = Telerik.WinControls.ElementVisibility.Visible;

RadPageViewContentAreaElement content = e.CellElement.TableElement.Parent as RadPageViewContentAreaElement;

if (content != null)

{

RadLabelElement el = content.FindDescendant<RadLabelElement>();

if (el != null)

{

content.Children.Remove(el);

el.Dispose();

}

private GridViewTemplate CreateChildTemplate1()

{

GridViewTemplate childTemplate = new GridViewTemplate();

this.radGridView1.Templates.Add(childTemplate);

GridViewTextBoxColumn column = new GridViewTextBoxColumn("FundName");

childTemplate.Columns.Add(column);

column = new GridViewTextBoxColumn("Amount");

childTemplate.Columns.Add(column);

childTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

childTemplate.Caption = "11";

return childTemplate;

}

private GridViewTemplate CreateChildTemplate2()

{

GridViewTemplate childTemplate = new GridViewTemplate();

this.radGridView1.Templates.Add(childTemplate);

GridViewTextBoxColumn column = new GridViewTextBoxColumn();

childTemplate.Columns.Add(column);

childTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

childTemplate.Caption = "aa";

return childTemplate;

}

Thanks

Excel export number format

Hi,

If I apply a Number Format to aggregate values, e.g. #.00 €, this also applies to Print, but not to Export to xlsx (but applies to export to XML). Is is possible to apply number format to xlsx Export as well?

Thanks,

Alex
