[Solved] CheckBoxColumn Colored CheckMark Primitive?

Hi Telerik

I'm trying to color the checkmarks in two GridViewCheckBoxColumns in a grid in our app. I have tried the following code but have only succeeded in producing visual gibberish. The entire grid is destroyed - my fault :-)

Could you please provide some guidance.
Many thanks in advance
regards
Ian Carson

void rgvOperationsGrid_ViewCellFormatting(object sender, CellFormattingEventArgs e)

{

if (e.ColumnIndex == 2)

{

((RadCheckBoxElement)e.CellElement.Children[0]).CheckMarkPrimitive.CheckElement.ForeColor = Color.DarkGreen;

}

else if (e.ColumnIndex == 3)

{

((RadCheckBoxElement)e.CellElement.Children[0]).CheckMarkPrimitive.CheckElement.ForeColor = Color.DarkRed;

}

RadCalendar control date selection

Hey everyone,

I just started working with the Telerik RadCalendar control, and it looks promising to be able to accomplish what I want. I do, however, seem to be running into an issue.

Using the arrow keys and space bar to select/deselect dates works great, but when I use the mouse to do this, it is awkward. I found a post relating to the issue, (http://www.telerik.com/community/forums/winforms/calendar-and-datetimepicker/urgent-radcalendar-not-deselect-dates-correctly.aspx) The Telerik representative mentioned that the reason this felt awkward was because of the "Focus Date" feature.

I understand how this works, but would it be possible to somehow change the color of the "Focus Date" part of the calendar? I think this would help my end users tell the difference between the "Focus Date" and a recently deselected/selected cell.

Thanks

Timezone Issue in Month + Timeline view

Hi
I'm using Q2 2011 SP1 (v2011.2.11.0831) and have discovered differences in Appointment.Start + End DateTime values between Dayview Viewtypes and Monthview,Timelineview.

//all views are initialized with

if (utcPlusOneTimeZone == null)

{

//utcPlustOneTimeZoneInfo = new SystemTime.TimeZoneInformation();

//utcPlustOneTimeZoneInfo = TimeZoneInfo.Local;

//utcPlustOneTimeZoneInfo.bias = -60;

//utcPlustOneTimeZoneInfo.daylightBias = -60;

//utcPlusOneTimeZone = new SchedulerTimeZone(utcPlustOneTimeZoneInfo, "CH");

utcPlusOneTimeZone = new SchedulerTimeZone(TimeZone.CurrentTimeZone);

}

switch (vt)

{

case SchedulerViewType.Day:

if (_dayView == null)

{

_dayView = radScheduler1.GetDayView();

_dayView.DefaultTimeZone = utcPlusOneTimeZone;

}

break;

case SchedulerViewType.Month:

if (_monthView == null)

{

_monthView = radScheduler1.GetMonthView();

_monthView.DefaultTimeZone = utcPlusOneTimeZone;

}

break;

case SchedulerViewType.Timeline:

if (_timelineView == null)

{

_timelineView = radScheduler1.GetTimelineView();

_timelineView.DefaultTimeZone = utcPlusOneTimeZone;

}

break;

//save function calls webservice

DateTime start = app.Start.ToLocalTime();

DateTime end = app.End.ToLocalTime();

if (systemService.ChangePlanningElement(app.ElementGID.ToString(), start,end)) return true;

- Month + Timelineview : app.Start.Kind = Unspecified and ToLocalTime() adds 2hours (utc+1 + Summertime)
- other dayview type : app.Start.Kind = Local and and ToLocalTime() = 0

//Workaround before calling webservice

TimeSpan tsOffset = app.Start.ToLocalTime() - app.Start;

DateTime start = app.Start.ToLocalTime() - tsOffset; //subtracts 0 or Timezonedifference

Why ist MonthCellElement.Date of Type Unspecified with TimezoneOffset=2h and SchedulerCellElement.Date of type Local with TimezoneOffset=0h

Thanks for clearing, Daniel

RadGridviewExcelExporter errors on Citrix

Greetings all

I have a simple winform app that loads a RadGridView and optionally exports it to Excel. The app works fine in the Development environment and as a standalone exe. However, when the code is moved to Citrix, the invocation of the RadGridViewExporter.Export method triggers an Excel error: "an error occured and this feature is no longer functioning properly". Once this error dialog is clicked, the export happens successfully.

I understand from various searches that this is likely a config issue with the server and not a Telerik internal problem. My hope is that someone has hit this before and might suggest a work-around from the application side.

We are using VS2010, .Net 4.0, and Q2/2011 Radcontrols for Winforms.

Relevant code follows. Many thanks for any advice.

private void Export(String filepath)

{

//this.radButtonExport.Enabled = false;

exporter =

new RadGridViewExcelExporter();

BackgroundWorker worker = new BackgroundWorker();

worker.DoWork +=

new DoWorkEventHandler(DoWork);

worker.RunWorkerCompleted +=

new RunWorkerCompletedEventHandler(bg_RunWorkerCompleted);

worker.RunWorkerAsync(filepath);

exporter.Progress +=

new ProgressHandler(exportProgress);

radProgressBar1.Visible = true;

radProgressBar1.Text =

string.Format("Exporting to {0}", filepath);

radProgressBar1.Width = radGridView1.Width * 2/3;

}

private void DoWork(object sender, DoWorkEventArgs e)

{

exporter.Export(radGridView1, (

String)e.Argument, "script results");

}

PageView Page and Anchoring

Hello,

I have some strange effects when using Anchor Bottom / Anchor Right with Controls placed on a PageView Page. The Controls do not keep their positions correcty. Also, the Designer (VS2010) seems to garble up sometimes.
Anyone else having issues with this?

Regards
Erwin

[Solved] radGridView1_CustomSorting event not firing

Hey everyone,

Title Correction: radGridView1_CustomGrouping event not firing

I am trying to implement the following example I have found in the Telerik forums to get custom month sorting to work. (Link) I tried setting the CustomDataOperation on the column as the example indicates. When I did that, the Intellisense description stated that the CustomDataOperation property was deprcated and to use EnableCustomGrouping, EnableCustomSorting, etc on the GridView instead.

I have set all of these properties to true, yet the radGridView1_CustomSorting event does not fire.

Why? What else is needed?
