Insert HTML text into existing RadDocument

Hi Telerik forum,
I began to use the RichTextEditor to create programmatically a radDocument (so i use the paragraph, span, section object to create it).
Once the document is shown, users can insert formatted paragraph to personalize the document. The html text paragraph are stored in database in html format.

The thing i need is to be able to insert formatted html paragraph into this raddocument already generated.
My problem is to evaluate all the html text (with differents tags inside it, span, table, tr etc). I use the HtmlFormatProvider that works perfectly but it produce a new raddocument. So i tried to convert the htmlformatprovider document into a DocumentFragment, but i have to use fragment.EnumerateChildrenOfType(Of object) and explicitly specify the object type (what i wouldn't do).
What's the best approach to insert html text into an existing raddocument ?

Thanks for your help, hoping that my question is clear.

Here's my sample code :

Dim document As New RadDocument

Dim section As New Section

Dim p9 As New Paragraph

Dim presta1 As New RadDocument

Dim msgHtml = New Html.HtmlFormatProvider

presta1 = msgHtml.Import(

"<SPAN><STRONG>Table content :</STRONG></SPAN><TABLE STYLE='border:1px solid black'><TR><TD>Marque</TD><TD>Type</TD><TD>N° série</TD><TD>Fluide</TD></TR><TR><TD>-</TD><TD>-</TD><TD>-</TD><TD>-</TD></TR><TR><TD>-</TD><TD>-</TD><TD>-</TD><TD>-</TD></TR></TABLE>"

)

Dim fragment = New DocumentFragment(presta1)

section.Blocks.Add(fragment.EnumerateChildrenOfType(Of Table).ToList.First) 'its working but only with Table tag

'Saut de ligne

section.Blocks.Add(New Paragraph)

document.Sections.Add(section)

return document

RadRibbonBar...RadSplitButtonElement: different behavior in different versions

The following sample code creates a RadRibbonBar\RibbonTab\RadRibbonBarGroup\RadSplitButtonElement UI structure.

Clicking on the radSplitButtonElement1 button causes the click handler (radSplitButtonElement1_Click) to be called twice.

Tested in R3 2017. This is not how it worked in Q1 2013, where the handler was called once.

Is this a bug or an intended change in behavior?

using System.Diagnostics;

using Telerik.WinControls.UI;

this.radSplitButtonElement1.DefaultItem = mni1;

mni1.Click += radSplitButtonElement1_Click;

RadMenuItem mni2 = new RadMenuItem("item2", 2);

Hello
I want to export data from multiple RadGridView to a single Excel file with multiple sheet. What I tried now it can export only 1 gridview to 1 file, if I try to export to same file, it was overwritten.

I did a search and found that it can't be done during last year. not sure what is the current status now.

http://www.telerik.com/community/forums/winforms/gridview/export-to-excel-with-gridview.aspx

Could anyone provide me an example please?

GanttView Time Range Day Does not display properly

I have a gantt view that I want to populate with data, but when i set it to the day range the the major timeline grid sizing seems to scale to the size of the container rather than to the secondary time line grid (see attached picture). The gantt view items are properly scaled to the major grid, but the secondary timeline markings are wrong. Is there a setting that i can use to make the major timeline grid marks stretch over all the available secondary timeline markings?

This is running on windows 10, telerik ui for winforms 2016 R3.

To replicate the issue create a new project with a gantview and use the following code in the load function.

RadGanttView1.GanttViewElement.GraphicalViewElement.TimelineRange = Telerik.WinControls.UI.TimeRange.Day
RadGanttView1.GanttViewElement.GraphicalViewElement.TimelineStart = Today
RadGanttView1.GanttViewElement.GraphicalViewElement.TimelineEnd = Today.AddHours(24)
Dim tasks As New DataTable("Tasks")
tasks.Columns.Add("Id", GetType(Integer))
tasks.Columns.Add("ParentId", GetType(Integer))
tasks.Columns.Add("Title", GetType(String))
tasks.Columns.Add("Start", GetType(DateTime))
tasks.Columns.Add("End", GetType(DateTime))
tasks.Columns.Add("Progress", GetType(Decimal))
Dim links As New DataTable("Links")
links.Columns.Add("StartId", GetType(Integer))
links.Columns.Add("EndId", GetType(Integer))
links.Columns.Add("LinkType", GetType(Integer))
Dim data As New DataSet()
data.Tables.Add(tasks)
data.Tables.Add(links)
tasks.Rows.Add(1, 0, "Summary task title", Today.AddHours(11), Today.AddHours(12), 30D)
tasks.Rows.Add(2, 1, "First child task title", Today.AddHours(11), Today.AddHours(11.5), 10)
tasks.Rows.Add(3, 1, "Second child task title", Today.AddHours(11.5), Today.AddHours(12), 20D)
tasks.Rows.Add(4, 1, "Milestone", Today.AddHours(12), Today.AddHours(12), 0D)
links.Rows.Add(2, 3, 1)
links.Rows.Add(3, 4, 1)
Me.RadGanttView1.GanttViewElement.TaskDataMember = "Tasks"
Me.RadGanttView1.GanttViewElement.ChildMember = "Id"
Me.RadGanttView1.GanttViewElement.ParentMember = "ParentId"
Me.RadGanttView1.GanttViewElement.TitleMember = "Title"
Me.RadGanttView1.GanttViewElement.StartMember = "Start"
Me.RadGanttView1.GanttViewElement.EndMember = "End"
Me.RadGanttView1.GanttViewElement.ProgressMember = "Progress"
Me.RadGanttView1.GanttViewElement.LinkDataMember = "Links"
Me.RadGanttView1.GanttViewElement.LinkStartMember = "StartId"
Me.RadGanttView1.GanttViewElement.LinkEndMember = "EndId"
Me.RadGanttView1.GanttViewElement.LinkTypeMember = "LinkType"
Me.RadGanttView1.GanttViewElement.DataSource = data

I want to know if a specific point is the sea or land.

Hello, I am a user using telerik winforms.
I am gratefully using radmap.
But I can not solve this problem, so I leave a post.

I am doing research to simulate drifting objects in the ocean.
But since a drifting object can not pass through the ground, I need a way to know if the specific coordinates are in the ground or in the sea.
It seems difficult to solve this method using 'Elevation'.

to sum it up,
Whether there is a way to know whether a specific point is the sea or the land.

Thank you.

FolderBrowserDialog in PropertyGrid

Hi,
In my application I use RadPropertyGrid and I create set of properties for it in my code using RadPropertyStore.

Before I started to use RadPropertyGrid all properties were displayed in group-boxes with different controls like text-box, drop-down and button. It was a mess.
One of the properties should contain path to some local directory. And in old implementation it was displayed by text box and browse button that was opening FolderBrowserDialog
.
As you might already imagine, my question is how can I insert FolderBrowserDialog to RadPropertyGrid?
What I have managed to do is below:

public partial class SettingsManager : UserControl

{

public SettingsManager()

{

InitializeComponent();

_propertyStore = CreateProperties();

radPropertyGrid1.SelectedObject = _propertyStore;

radPropertyGrid1.PropertySort = PropertySort.CategorizedAlphabetical;

}

private RadPropertyStore _propertyStore;

private PropertyStoreItem _defaultSaveDirectory;

private RadPropertyStore CreateProperties()

{

var result = new RadPropertyStore();

_defaultSaveDirectory = new PropertyStoreItem(typeof(string),

"DefaultSaveFolder",

Properties.Settings.Default.DefaultSaveFolderPath,

"Default directory for saving snapshot and configuration files.",

"Save Snapshot/Configuration",

false);

_defaultSaveDirectory.PropertyChanged += OnDefaultSaveDirectoryChanged;

result.Add(_defaultSaveDirectory);

return result;

}

void OnDefaultSaveDirectoryChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)

{

var folderDialog = new FolderBrowserDialog {

Description = Resources.DefaultLocationDialogHelp,

ShowNewFolderButton = true

};

if (DialogResult.OK == folderDialog.ShowDialog())

{

_defaultSaveDirectory.PropertyChanged -= OnDefaultSaveDirectoryChanged;

_defaultSaveDirectory.Value = folderDialog.SelectedPath;

_defaultSaveDirectory.PropertyChanged += OnDefaultSaveDirectoryChanged;

Properties.Settings.Default.DefaultSaveFolderPath = folderDialog.SelectedPath;

}

But I have two problems with this implementation:
1) FolderBrowserDialog opens on initialization
2) There is no such a thing like Click event for PropertyStoreItem, so user have to really change the property value in order to FolderBrowserDialog to appear

RadMaskedEditBox value minus mask

It's really not that complicated to manually remove "mask" characters from a string but I was curious if this control already has this ability built in?

Here's an example:

assume ctrl = RadMaskedEditBox

ctrl.Mask = "00000-9999"

ctrl.Text = "_____-____"

ctrl.MaskType = Standard

If the user gets to this input box and types in "12345" and I check ctrl.Value I get this: "12345-____" when what I really want is "12345"

If I'm missing something, please advise otherwise, i'll just grunt my way through it :)

Thanks everyone!!!

-Curtis
