Hi,

 We are using RadEditor Export PDF functionality.

  Export to PDF getting Javascript Error "Error while executing filter ConvertFontToSpanFilter - InvalidCharacterError: Failed to execute 'setAttribute' on      'Element': 'font-family:arial,' is not a valid attribute name.

We tried to Disable ConvertFontToSpanFilter Filter. Then PDF is not downloaded and getting below Error

System.ArgumentException: String cannot be of zero length. Parameter name: oldValue at System.String.ReplaceInternal(String oldValue, String newValue) at System.String.Replace(String oldValue, String newValue) at System.Text.RegularExpressions.RegexReplacement.Replace(MatchEvaluator evaluator, Regex regex, String input, Int32 count, Int32 startat) at System.Text.RegularExpressions.Regex.Replace(String input, MatchEvaluator evaluator) at Telerik.Web.UI.Editor.Export.ApocPdfGenerator.ValidateContentForExport(String content) at Telerik.Web.UI.Editor.Export.RadEditorExportTemplate.GenerateXmlStirng(String pageTitle, String content) at Telerik.Web.UI.Editor.Export.RadEditorExportTemplate.InitializeXmlContent() at Telerik.Web.UI.Editor.Export.RadEditorExportTemplate.Export() at

i have a problem in uploading files via RadAsyncUpload when i open the page that contains the telerik upload controls

the following error rises -->

in localhost working fine but in my website does not work ,

so i contacted to the host provider and asked to set full permission to App_Data an the Target folder and sub folders so they set the permission and still i get the above error ,

then i set UseApplicationPoolImpersonation to True and impersonate to true in web.config but still no hope same error,

what can i do to fix this error 

note: before the host provider update iis to 10 the upload was working.

I am using the Panelbar for navigation. The Panelbar expands when a category button is clicked. When a child item is selected in the Panelbar and navigate to page, the Panelbar collapses. The Panelbar should stay open until another item on the same level is selected. The user must reopen the menu item to select another item from the same level. In my case two levels collapse, back to original setting when web site opened. 

The menu looks like this:

Major Category 1 (Always expanded)

  Item 1

  item 2

  Item 3

Major Category 2

  Minor Category 1

    Item 1   Selecting any of these items will collapse everything back to Major Category 2

    Item 2

    Item 3

 Minor Category 2

    Item 1    Selecting any of these items will collapse everything back to Major Category 2

    Item 2

We have these settings:

ExpandMode="MultipleExpandedItems"  This is selected because we have the most used items expanded all the time and then less used items in major categories with sub categories then child items.

Prevent collapse does not let the panel ever collapse once it has been opened

What setting do we use so the panelbar will remain expanded until another item on the same level is expanded?

We are using ASP.NET with Ajax  version: 2011.2.712.40

Have data as follows:

Column:  PrimaryKey: (Int32) ResourceId - not null

Column: (Int32?) : ParentId - can be null.

So top level ParentId fields for ResourceId's will be null.

<SelfHierarchySettings KeyName="ResourceId" ParentKeyName="ParentId" />

Do I have to use a NeedDataSource? Why?

Spent hours trying to get a seemingly simple 5 minute exercise to get a self-referencing grid to work.  Paging is off.  Googled and Stack-Overflow for hours - nobody has had this problem?  Help Please ?

Thanks..

Hi.

I am new to kendo scheduler. Please help me with following issue:

DTSTART:20170614T133000Z // This is event start time

DTEND:20170614T140000Z // This is event end time

Recurrence rule: FREQ=YEARLY;INTERVAL=2;UNTIL=20260616T182959Z;BYMONTH=6;BYMONTHDAY=14

I am using following method in my SQL procedure to get all event occurence between 'rangestartdate' and 'rangeenddate'

SELECT * FROM dbo.ExpandRecurrence('DTSTART:20170614T133000Z ' + Char(10) + 'DTEND:20170614T140000Z ' + Char(10) + 'RRULE:FREQ=YEARLY;INTERVAL=2;UNTIL=20260616T182959Z;BYMONTH=6;BYMONTHDAY=14',  'rangestartdate'  ,'rangeenddate' )

I consider, the event start date to be the 'rangestartdate'.The problem is how to determine, the value for 'rangeenddate'??

Please reply, as i am stuck with this problem and finding no solution elsewhere.

Thanks

I have attached 2 files. An aspx page and a code behind vb page. I am trying to apply filter by implementing filter template. I have a radcombobox that filters the radgrid. 

Datasource for the radgrid is a dataset defined in aspx.vb. There are 2 tables in the dataset

Radcombobox datasource is a datatable from the above dataset defined in aspx.vb.

Trying to rebind the radgrid after the radcombobox selection both in code behind and on aspx via JS. 

1) using the following lines in cmbStateSelectedIndexChanged event does not rebind the grid.

2) using FilterExpression in radgrid prerender does not rebind the grid

3) using filtering in aspx page does not rebind grid.

In my first and second cases after I select a state and I do rg_dynamic.MasterTableView.Rebind(), the cmbState will not hold the selected value.

In my third case applying just that code to filter the grid on aspx side (that is commenting filter expression code in grid prerender and combobox selected index changed server side events) will hold the selected value. 

I have the datasource available for both grid and combox box on my server side. The grid will not rebind post filtered value. I came across an example on your forum pages http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/filter-templates/defaultcs.aspx
But it is not helping me.

Any help on this is appreciated.

Here is my aspx.vb
