Cannot Edit Cell on Databound Grid

Hi,

I'm still new to Telerik and having a hard time editing cell in the grid when selected the row.

below is my Linq .

var voters = (

from voter in db.VotersLists

.OrderBy(c => c.Barangay)

from data in db.VotersDatas

.Where(b => b.RecId == voter.ID)

.DefaultIfEmpty()

from leader in db.VotersLists

.Where(d => d.ID == data.LeaderID)

.DefaultIfEmpty()

select new

{

ID = voter.ID,

VotersID = voter.VotersID,

Precinct = voter.Precinct,

Name = voter.Name,

Birthday = voter.Birthday.GetValueOrDefault().ToShortDateString(),

Sex = voter.Sex,

Barangay = voter.Barangay,

Address = voter.Address,

PoliticalParty = data.PoliticalParty,

IsRD = data.IsRD,

LeaderName = leader.Name,

LeaderPosition = data.LeaderPosition

,DataID = data.ID.ToString() == null ? "" : data.ID.ToString()

});

dg2.DataSource = voters;

I tried using the code below and it won't work.

dg2.Rows[dg2.CurrentRow.Index].Cells[10].Value = "Test";

or

if (this.dg2.CurrentRow is GridViewRowInfo)

{

GridViewRowInfo editRow = dg2.CurrentRow;

editRow.Cells["LeaderName"].Value = "TEST";

}

Control Scaling on Forms

Hello,

I can't seem to get various controls (button, label, dropdown, etc.) to scale correctly when the form font size is changed. Actually the size of the control appears to be scaled correctly but the font size of the control remains the same.

For example, create a new application and drop a radbutton on the form. In the form constructor add a change to the form font size:

Public Sub New()

' This call is required by the designer.

InitializeComponent()

' Add any initialization after the InitializeComponent() call.
Dim sysFont As Font = SystemFonts.MessageBoxFont
Me.Font = New Font(sysFont.Name, 14, sysFont.Style)
End Sub

At run-time the size of the button increases (good) but the font size remains at the default 8.25. This is not how the MS controls behave when added to the same form. The MS button size and font size change accordingly.

The form AutoScaleMode is set to Font.

Am I missing something?

Selectionchanged event firing

I am new to Telerik and is trying to run the selection changed event for my gridview when select different rows. I have the code for the function, but I do not have the code to call this event. I know the event code for the button is generated in the designer.cs when I double click on the button in the form, but how do I generate an event for selection changed and other events which I cannot see? Do I have to add it in to the Designer manually?

private void gvUser_SelectionChanged(object sender, Telerik.WinControls.UI.SelectionChangedEventArgs e)
{
}

What's the best way to select/replace specified docfragment content inserted programmatically ?

Hi Telerik Forum,
I'd like to put a bookmark (or another marker) on severals fragment doc (inserted programmatically into the radrichtexteditor) in order to easily select them / delete them / replace the whole text/table inside them. I tried to use textrange object in order to do it but without success.
I don't know what's the best approach to do theses actions above.

Some precision about my app :
* my paragraphs text comes from database in html format, so i use htmlprovider to insert them into my final document
* user can modify paragraph with different buttons in order to change the defaults paragraphs generated before

Thx for your help :)

Here's my sample code :

Shared Sub GenerateDocument(rte As RadRichTextEditor)

Dim document = New RadDocument()

rte.Document = document

Dim htmlProvider = New HtmlFormatProvider()

Dim parHtml1 =

"<span>Start of Paragrah1</span><br/><table style='border:1px solid black'><tr><td>Desc.</td><td>Value</td></tr><tr><td>Variable1</td><td>10.23</td></tr></table>Some text after the table<br/><span>End of Paragrah1</span><br/>"

Dim parHtml2 =

"<span>Start of Paragrah2</span><br/>Some text before creating table<table style='border:1px solid black'><tr><td>Desc.</td><td>Value</td></tr><tr><td>Variable2</td><td>50.18</td></tr></table><br/><span>End of Paragrah2</span><br/>"

'Converting html to raddoc

Dim docPar1 = htmlProvider.Import(parHtml1)

Dim docPar2 = htmlProvider.Import(parHtml2)

'Creating fragments

Dim fragmentPar1 = New DocumentFragment(docPar1)

Dim fragmentPar2 = New DocumentFragment(docPar2)

Dim documentEditor As New RadDocumentEditor(document)

'Inserting paragraph 1

rte.Document.CaretPosition.MoveToLastPositionInDocument()

documentEditor.InsertBookmark("bookmarkPar1")

documentEditor.InsertFragment(fragmentPar1)

'Inserting paragraph 2

rte.Document.CaretPosition.MoveToLastPositionInDocument()

documentEditor.InsertBookmark("bookmarkPar2")

documentEditor.InsertFragment(fragmentPar2)

'Trying of selecting / delete / replace all content in specified bookmark (that doesn't work)

SelectAndUpdateContentBookmark("bookmarkPar1", rte, String.Empty) 'only select

SelectAndUpdateContentBookmark("bookmarkPar2", rte, "New content") 'select and replace with new text

End Sub

Shared Sub SelectAndUpdateContentBookmark(ByVal bookmarkName As String, rte As RadRichTextEditor, newContent As String)

rte.Focus()

Dim bookmarks() As BookmarkRangeStart = rte.Document.GetAllBookmarks().ToArray()

Dim posstart As New DocumentPosition(rte.Document)

Dim posend As New DocumentPosition(rte.Document)

Dim item = bookmarks.Where(Function(x) x.Name = bookmarkName).FirstOrDefault

If item IsNot Nothing Then

rte.Document.GoToBookmark(item)

posstart.MoveToInline(TryCast(item.FirstLayoutBox, InlineLayoutBox), 0)

posend.MoveToInline(TryCast(item.End.FirstLayoutBox, InlineLayoutBox), 0)

posstart.MoveToNextInline()

rte.Document.Selection.SetSelectionStart(posstart)

rte.Document.Selection.AddSelectionEnd(posend)

'Replacing with new content

If Not String.IsNullOrEmpty(newContent) Then

rte.Delete(False)

rte.Insert(newContent)

End If

End Sub

Gradient in legend

I have a series where I am using the "LabelFormatting" event to color scatter points individually, and I would like to paint the legend item as a gradient to reflect that is not a single color but I cannot tell how to accomplish it. I am also using something I saw in the forums for adding checkboxes to the legend via handling the VisualItemCreating and replacing with my own derived LegendItemElement. After creating the child elements I am looking at the legend item marker and I see a lot of properties for gradients but no way to activate them.

I've also tried setting the BackColor and BackColor2 of the series, as well as NumberOfColors = 2 with no effect.
