SelectedRows are not cleared when using Begin and EndUpdate

I'm facing a problem while updating the DataTable. The SelectedRows list references the old objects when updating the DataTable using BeginUpdate and EndUpdate.

code snippet is as follows:

gridView.GridElement.BeginUpdate();

DataTable dt = gridView.DataSource as DataTable;

dt.Clear();

// Loops a list and add DataRows with dt.NewRow() function

gridView.GridElement.EndUpdate();

Upon execution of the above code, the SelectedRows should ideally be cleared. However, they are still having objects in the List.
I'm not facing this issue when BeginUpdate() and EndUpdate() function is not used.

I'm using Q1 2010 SP2.

I understand that this is a old version and it might have got resolved in latest versions, however, I'm not in a state to upgrade. Please suggest me some workaround for this.

Resizing and fixing a ToolWindow

I have four ToolWindows added dynmaically to a RadControl. These always render with equal sizes. I want to make one of these a smaller fixed size with the others bigger to make up the difference. I have tried setting the ToolWindow Height, the DockTabStrip Height, I've set the TabStrip.SizeInfo.SizeMode to Absolute, everything I try has no effect on the height.

I'm new to winforms and am struggling here. Any help would be most welcome.

Multiview calendar show 1 full year help needed

Hey all,

I have a multiview calendar that has 6 columns and 2 rows and I need to show January as the first month and December as the last month (for any selected year). I have set the rangemin to January 1st (selected year) and the rangemax to December 31st (selected year), however this does not cause January to be the first month, the first month is whatever the current month is (in this case March). So I tried setting the focusdate to January 1st (selected year) and that works, however it causes the calendar to look like January 1st is selected, which causes confusion because the user is looking at all of their scheduled working days for the year. I've tried to reset the focusdate to another date (that is a working day, thereby "hiding" the focusdate) within the selected year and that seems to work, however it seems like a workaround and I'm wondering if there is a better way to do what I'm doing.

I would think there is an easy way to set the first/last displayed month without having to set the focusdate. If anyone knows how to do this please let me know.

Also, how do I get rid of the border around today's date?

Thanks!

edit: Tried this, CalendarElement.Calendar.DefaultView.ViewStartDate = "1/1/" & GoalYear but that doesn't work either.

edit2: The above code allows me to click on the calendar header and then I can see that "View" and select it, however I need it auto selected of course

edit3: Ok, I'm seeing really weird behavior. I'm attaching 3 screenshots to show, but basically when the form loads the header says "January 2011-December 2011", however the calendar's start at March 2011 (screenshot 1). When I click on the header I get 2? view options, "January 2011-December 2011" and "December 2011-November 2012" (screenshot 2). If I select "January 2011-December 2011" (which is what I want it to load as) then the result is screenshot 3, which is correct.

Filter Resources by Visibility

Hi

I want to use the grouping function of radScheduler to only group visible resources.
But it does not work, it always shows all resources.
What am I doing wrong?

*** sample code loading Resources

Resource tempResource = null;

            recResourceGroup[] resourceGroups = plannerSettings.recResourceGroup;
            foreach (recResourceGroup resourceGroup in resourceGroups)
            {
                tempResource = new Resource("G-"+resourceGroup.No,resourceGroup.Name);
                tempResource.Visible = false;
                tempResource.Color = Color.Orange;
                plannerSchedule.Resources.Add(tempResource);

                recResource[] resources = resourceGroup.recResource;
                foreach (recResource resource in resources)
                {
                    string sKey = resource.IsRentalItem.ToString() == "1" ? "M" : "R";
                    sKey += resource.VirtualResource.ToString() == "1" ? "V-" : "-";
                    tempResource = new Resource(sKey+resource.No,resource.Name);
                    tempResource.Visible = false;
                    tempResource.Color = Color.Green;
                    plannerSchedule.Resources.Add(tempResource);
                }
            }

*** sample code loading Appointment-Resources

foreach (recResourceAssigned planningAssignedResource in planningAssignedResources)
{
    string sKey = null;
    switch (planningAssignedResource.Type.ToString())
    {
        case "0": //resource
            {
                sKey = "R-" + planningAssignedResource.No.ToString();
            }
            break;
        case "1": //resourceGroup
            {
                sKey = "G-" + planningAssignedResource.No.ToString();
            }
            break;
        case "2": //workPlace
            {
                sKey = "W-" + planningAssignedResource.No.ToString();
            }
            break;
        default:
            {
                //error not supported
            }
            break;
    };
    schedulerApp.ResourceIds.Add(plannerSchedule.Resources.GetById(sKey).Id);
}

*** Sample code switching visibility of Resources

foreach (Resource resource in radScheduler1.Resources)
{
      string tempKey = resource.Id.KeyValue.ToString();
      switch(groupby)
      {
          case "resource":
              resource.Visible = tempKey.Contains("R-") ? true : false;
              break;
          case "resourceGroup":
              resource.Visible = tempKey.Contains("G-") ? true : false;
              break;
          case "workplace":
              resource.Visible = tempKey.Contains("W-") ? true : false;
              break;
          case "order":
              resource.Visible = tempKey.Contains("J-") ? true : false;
              break;

              resource.Visible = false;
              break;
       }

Font of dropdown grid

Hello!

Is it possible to set the font of the dropdown grid other then default "Segoe UI" ?

The expected behavior is that the grid must use the same font as RadMultiColumnComboBox.

The code I tried to use is similar to this:

RadMultiColumnComboBox combo = new RadMultiColumnComboBox();

combo.Font =new System.Drawing.Font("Microsoft Sans Serif", 8.25F);

combo.EditorControl.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F);

But the dropdown grid still uses Segoe UI Font.

IDE minor UI bug

FYI...you might already know this, but there appears to be a slight alignment bug in the GridView property builder. I tried resizing the window but it did not fix it. No real issue but just a friendly heads up. See screenshot.

Random Designer Problem

Ok, I don't know if this is an issue with RadControls, or just Visual Studio in general, but basically, I can't select different pages on a pageview, or anything that has child controls within the designer. Also, the bottom gray area of the designer now shows ALL controls that are on the form, instead of just things like timers, background workers, etc. (see screenshot).

If anyone has run into this before, any ideas what's up?

Thanks!!
