Cannot find Property to change CheckMark Color for a CheckBox

Dear Telerik team,
I am designing a style for CheckBox control and the problem i face is "I cannot find property to change CheckMark color and backColor of the box for check mark. The property i guess would have worked is "RadCheckBoxElement.ToggleState=Ok.Pressed. But this property produces arrows etc ( for whatever shape i choose from available options)

none of the property changes the dark brown color of check and the box.

Thanks

HTMLFormatProvider and font-style problem

Hi all,
I've a problem with HTMLFormatProvider and font-style.
I'm using a radRichTextBox with richRibbonBar (but the problem is also present with a button that execute radRichTextBox1.toggleItalic() ). For example, I have write the string "foofoofoo" in italic inside radRichTextBox and then, using HTMLFormatProvider, I've got the text associated to the document.

This is the ExportToHTML function

public string ExportToHTML(RadDocument document)
{
HtmlFormatProvider provider = new HtmlFormatProvider();
return provider.Export(document);
}

This is the string returned:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>Untitled</title><style type="text/css">
.p_4451D050 { margin: 0px 0px 12px 0px;text-align: left;text-indent: 0pt;padding: 0px 0px 0px 0px; }
.s_C54C634B { font-family: 'Calibri';font-style: System.Collections.Specialized.StringCollection;font-size: 16px;color: #000000; }
</style></head><body><p class="p_4451D050"><span class="s_C54C634B">foofoofoo</span></p></body></html>

There is a problem in font-style settings of css class, because it doesn't write "italic" but "System.Collections....".
So, when I send a html-email in this format I lost this font setting..

I've tried with XamlFormatProvider and italic (as fontweight) is correct.

Thanks a lot for your help

ErrorProvider Icon in RADGridViewCell

After searching the forums for some time (days, well 2 days) I finally have a solution on displaying an Error Icon in a cell of a RADGridView i.e. like in SQL Management Studio when a certain criteria is met.
Scenario 1: Validate all cells in a row simultaneously
Scenario 2: Validate an individual cell

So here goes:
Solution 1: Validate all cells in a row simultaneously

Private Sub rgvSrcExtractFiles_RowValidating(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.RowValidatingEventArgs) Handles rgvSrcExtractFiles.RowValidating

If TypeOf e.Row Is GridViewDataRowInfo Then

For Each cell As GridViewCellInfo In e.Row.Cells

Select Case cell.ColumnInfo.Name

Case "FileDirectory"

If Not FileAcc.DirectoryExists(cell.Value) Then

cell.ErrorText = "Directory not found!"

ElseIf FileAcc.CountFilePrefixWithExt(cell.Value, e.Row.Cells("FilePrefix").Value, e.Row.Cells("FileExtension").Value) = 0 Then

cell.ErrorText = "No valid files found in directory!"

Else

cell.ErrorText = String.Empty

End If

Case "FilePrefix"

If FileAcc.CountFilePrefix(e.Row.Cells("FileDirectory").Value, cell.Value) = 0 Then

cell.ErrorText = "Files not found!"

Else

cell.ErrorText = String.Empty

End If

Case "FileExtension"

If FileAcc.CountFileExt(e.Row.Cells("FileDirectory").Value, cell.Value) = 0 Then

cell.ErrorText = "Files not found!"

Else

cell.ErrorText = String.Empty

End If

End Select

Next

End If

End Sub

Solution 2: Validate an individual cell

Private Sub rgvSrcExtractFiles_CellValidating(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.CellValidatingEventArgs) Handles rgvSrcExtractFiles.CellValidating

Dim column As GridViewDataColumn = TryCast(e.Column, GridViewDataColumn)

If TypeOf e.Row Is GridViewDataRowInfo AndAlso column IsNot Nothing Then

Select Case column.Name

Case "FileDirectory"

If Not FileAcc.DirectoryExists(e.Value) Then

DirectCast(e.Row.Cells(e.ColumnIndex), GridViewCellInfo).ErrorText = "Directory not found!"

ElseIf FileAcc.CountFilePrefixWithExt(e.Value, e.Row.Cells("FilePrefix").Value, e.Row.Cells("FileExtension").Value) = 0 Then

DirectCast(e.Row.Cells(e.ColumnIndex), GridViewCellInfo).ErrorText = "Files not found!"

Else

DirectCast(e.Row.Cells(e.ColumnIndex), GridViewCellInfo).ErrorText = String.Empty

End If

Case "FilePrefix"

If FileAcc.CountFilePrefix(e.Row.Cells("FileDirectory").Value, e.Value) = 0 Then

DirectCast(e.Row.Cells(e.ColumnIndex), GridViewCellInfo).ErrorText = "Files not found!"

Else

DirectCast(e.Row.Cells(e.ColumnIndex), GridViewCellInfo).ErrorText = String.Empty

End If

Case "FileExtension"

If FileAcc.CountFileExt(e.Row.Cells("FileDirectory").Value, e.Value) = 0 Then

DirectCast(e.Row.Cells(e.ColumnIndex), GridViewCellInfo).ErrorText = "Files not found!"

Else

DirectCast(e.Row.Cells(e.ColumnIndex), GridViewCellInfo).ErrorText = String.Empty

End If

End Select

End If

End Sub

AND TADA : **** THE MAGIC *****

Private Sub rgvSrcExtractFiles_CellFormatting(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles rgvSrcExtractFiles.CellFormatting

Dim cell As GridDataCellElement = TryCast(e.CellElement, GridDataCellElement)

If cell IsNot Nothing Then

If cell.ContainsErrors Then

'Uncomment to draw a red border around cell as well

'cell.DrawBorder = True

'cell.BorderBoxStyle = BorderBoxStyle.SingleBorder

'cell.BorderWidth = 2

'cell.BorderColor = Color.Red

'cell.ImageAlignment = ContentAlignment.MiddleRight

Dim prov As New ErrorProvider

Dim conv As New ImageConverter

cell.Image = conv.ConvertFrom(prov.Icon)

cell.TextImageRelation = TextImageRelation.TextBeforeImage

cell.ImageAlignment = ContentAlignment.MiddleRight

cell.ImageLayout = ImageLayout.None

Else

'Resets the borders to the original value

'cell.ResetValue(LightVisualElement.DrawBorderProperty, ValueResetFlags.Local)

'cell.ResetValue(LightVisualElement.BorderBoxStyleProperty, ValueResetFlags.Local)

'cell.ResetValue(LightVisualElement.BorderWidthProperty, ValueResetFlags.Local)

'cell.ResetValue(LightVisualElement.BorderColorProperty, ValueResetFlags.Local)

cell.Image = Nothing

End If

End Sub

That's it folks. You can use EITHER Solution 1 or 2, but you have to include the magic irrespective of which one you choose.
Hope this saves you some hours.

No AutoSizeRows for child template?

There is a property for the main masterviewtemplate of a RadGridView to set the rows to auto size if you have a column's WordWrap turned on (i.e., this.radGridViewRequests.AutoSizeRows = true ). This works slick.
BUT, for a child template there is no such property to AutoSizeRows if you have a column's WordWrap turned on. So what is one supposed to do to get the child template rows to resize properly?

ChartSeries z-order question

Hi,
I have a chart with 4 series (created programatically). 3 series are spline type and 1 is point type. I need the point type series to be on top of the spline series but i cannot find a way to make the point series to draw on top of the splines. Look at the attached image to see the problem.

I tried using series.BringToTop() but it crashes the app, I also tried changing the order of creating the series and order of adding them to the chart.Series container but that doesn't change the z-order. Any suggestions on how to accomplish this?
Thanks.

Draw border around a group of cells

Hi,

I want to draw a border around a group of cells. There should not be any border in between the group, only around.
Like highlighting a group. How can I achieve this?

And when i draw a border around a cell, like shown in this post, the border to the right seem like its only one pixel wide, and the rest is 2 px.How can I avoid this.

Please take a look at the attached picture. I also painted an example of the border around a group that i want to make possible in code :)
