Bug In RadDateTimePicker _onCellClickHandler event

I am using ASP.NET AJAX Q1 2010 and I am having some issues with firefox.

Scenario:
I adopted the sample at http://www.telerik.com/community/code-library/aspnet-ajax/calendar/how-to-use-raddatepicker-with-multimonthview-calendar.aspx and used it with RadTimePicker so the idea is that for selecting date, user can use multiple month calendar and then select time. However, on firefox, if first the user selects date and then selects time, the control renders invalid date (red border with invalid image).

Diagnosis:
So I traced through the code and the problem is in the click handler for the time view..

This is telerik code:

,_onCellClickHandler:function(k){var c=Telerik.Web.UI.Calendar.Utils.FindTarget(k,this.get_id());
if(c!=null){var g=c.cellIndex;
if(navigator.userAgent.match(/Safari/)){var h=c.parentNode;
var a;
for(a=0;
a<h.cells.length;
a++){if(h.cells[a]==c){g=a;
}}}var m=this._findTime(c.parentNode.rowIndex,g);
if(m!=null){this._onCellMouseOutHandler(k);
var j=this.getTime();
if(j!=null){m.setDate(j.getDate());
m.setMonth(j.getMonth());
m.setYear(j.getYear());
}var n=new Telerik.Web.UI.TimeViewSelectingEventArgs(m,j);
var d=this.raise_clientTimeSelecting(n);
if(!d){this.setTime(m.getHours(),m.getMinutes(),m.getSeconds(),m);
......................

The problem is in the bolded line. The getYear api is depreciated and instead getFullYear should be used. as if the date is Jan 5, 2011, on firefox, getYear returns 111 and when you do m.setYear(111), m's date is something wierd.
Now why does this error no manifest in all demos and normal situation is because, in setTime method we have:

,setTime:function(c,a,e,g){var f=$find(this.get__OwnerDatePickerID());

var d;

if(Object.getType(f).getName()=="Telerik.Web.UI.RadDateTimePicker"&&!f.get_calendar()){d=g;

}else{d=f.get_selectedDate();

}if(!d){d=new Date();

}d.setHours(c);

d.setMinutes(a);

d.setSeconds(e);

in normal scenario, the if condition would be false and hence d=f.get_selectedDate(); is executed. However, since I am using http://www.telerik.com/community/code-library/aspnet-ajax/calendar/how-to-use-raddatepicker-with-multimonthview-calendar.aspx, d = g is evaluated. And future down in the code, _setHiddenValue is called which actually verifies that the selected date is between min and max and this is where it fails.

Launch a radtooltip, radalert, or a plain alert in a usercontrol?

I seem to be having an issue, I am trying to launch a tooltip, radalert, or a plain alert in a usercontrol. When the user clicks a button I do some computation and then at the end of the method I try to launch a popup if it was successful. But I've been having some issues since the usercontrol reloads itself every time the button is clicked, and I needed it to reload it self.

I've tried showing the RadTootip/Alert server side but it didn't work then I tried setting the text of a literal to javascript at the end of the method but that didn't work.

Any ideas on how to show a popup at the end of a button click method?

IE7 memory leaks with Menu and Toolbar

I have a web form that uses RadMenu and RadToolBar on a form that displays a form view of records from a table (the form fields do not use Telerik controls). As the page is refreshed to show different records, each page loads slower and slower when using IE7. If I take off the Telerik controls, there's no problem. With IE8, also no memory problem (although it's still a lot slower than my own home-grown controls). Each time the page loads, IE7 gobbles up 15-20MB of memory, until I have to kill the browser. Any plans to fix this?

Insert Binary Image - RadGrid

I am trying to insert a file (PDF/JPG/XLS) into an image field in my SQL database. Thus far whatever I do, the file is inserted as a NULL value. The GridViewDataHyperLinkColumn is part of a nested detail table. All other fields update just fine.

<asp:SqlDataSource ID="sqlGetDocs" runat="server" OnInserting="SqlGetDocs_Updating"

ConnectionString="<%$ ConnectionStrings:DBConnectionString %>"

SelectCommand="spAspGetEnrollDocs" SelectCommandType="StoredProcedure"

InsertCommand="spASPinsertClientDocDatabase"

InsertCommandType="StoredProcedure">

<SelectParameters>

<asp:SessionParameter Name="SSN" SessionField="SSN" Type="String" />

</SelectParameters>

<InsertParameters>

<asp:ControlParameter ControlID="DropDownList1" Name="Client"

PropertyName="SelectedValue" Type="String" />

<asp:Parameter Name="SSN" Type="String" />

<asp:Parameter Name="DocDesc" Type="String" />

<asp:Parameter Name="FileType" Type="String" />

<asp:Parameter Name="ImageFile" dbType="Binary" />

<asp:Parameter Name="Updated" Type="DateTime" />

<asp:Parameter Name="Comments" Type="String" />

<asp:ControlParameter ControlID="lblUserName" Name="UserID" PropertyName="Text"

Type="String" />

</InsertParameters>

</asp:SqlDataSource>

If I add the following code - I receive an error where I declare "imageBytes":

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Protected Function UpdateImageField(ByVal gridEditableItem As GridEditableItem) As Byte()

Dim bytes As Byte() = (DirectCast(gridEditableItem.EditManager.GetColumnEditor("ImageFile"), GridBinaryImageColumnEditor)).UploadedFileContent

If bytes Is Nothing OrElse bytes.Length = 0 Then

bytes = New Byte() {}

End If

Return bytes

End Function

Protected Sub SqlGetDocs_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs)

Dim imageBytes As Byte() = UpdateImageField(TryCast(RadGrid.EditItems(0), GridEditableItem))

e.Command.Parameters("@ImageFile").Value = imageBytes

End

Sub



Could someone tell me what I'm doing wrong?

"Not Found" in Document Manager (5.6.2)

Problem:
When I, as a site collection admin, click on the DocumentManager icon, the pop up screen will show NOT FOUND for all the libraries. See attached screen shot.

Configuration:
I don't have the DocumentsPath tag at all in the config.xml

Attempts:
When I put the DocumentPath tag with root document, it will show up on the pop up screen with just that library.
   <property name="DocumentsPaths">
   <item>/Documents</item>
   <item>whatever</item>
   </property>
and "whatever" will show as NOT FOUND.

Other findings:
Another developer, who I believe has farm admin rights, can see all the libraries instead of NOT FOUND.
This also works on a few different site collections with a site collection admin but not for others.
We have this working a few months ago and not sure why it stopped working all of the sudden.
We have to leave it dynamic to go through all libraries

Is it a known bug and got addressed in the newer version?

Getting new values from Edit Mode

DISCLAIMER: I am brand new to the Telerik ASP.NET AJAX toolkit. So my apologies if these are truly "newbie" questions.

Environment: ASP.NET 3.5, Windows 7, IE 8, ASP.NET, Telerik ASP.NET AJAX Q3 2009 SP3

I have a RadGrid with a number of columns.
I have successfully bound the RadGrid to a DataTable in the C# code behind. When the grid is displayed, the correct values are shown.

Note: I am using stored procedures to populate my source DataTable. In order to update the database properly, I have to manually execute multiple stored procedures. So, it's my understanding that I can't use "Automatic" mode for this RadGrid. (Am I correct on this?)

When I click the Edit link on one of the grid's row, the row is changed to allow me to enter new values. (FYI, I've used both in-place and EditForm editing.)

The problem is that once I click the Update link, the new values I typed in are not saved. (My plan is to get the new values typed in, and then manually update the database via the various stored procs.)

I added an UpdateCommand event handler, but when I look at e.Item, it gives me the the old value, not the new value.

Please advise...

Thanks,

Mitch

protected void RadGridNextSteps_UpdateCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)

{

GridDataItem editItem = e.Item as GridDataItem; // found the row

TableCell cell = editItem["sDisplayText"]; // found the cell

TextBox txt = cell.Controls[0] as TextBox; // found the control

string itemValue = txt.Text; // found the control’s value

// Problem: itemValue is old value, not new value.

}

Export webpage to PDF and Word

Hi.

Is it possible to export the content of a webpage to PDF or Word or does the content have to be within a RadGrid, Telerik Report of RadEditor?

At a push I could get the content appearing in a RadEditor and use that components built in export functions but it's not ideal. And I can only Export to PDF or RTF. And the RTF format does not render html tables or images which means that's a non-starter.

Thanks
Chris
