Refresh sorting

Is there any way how to refresh sorting on RadGridView easy way (i.e. force grid to re-sort according actual sorting settings)? I'm now using following code, but it's kind of ugly.

    
            private void uxTourGrid_CellEndEdit(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)  
        
            {  
        
                if (e.ColumnIndex == 0 && uxTourGrid.Columns[0].SortOrder != RadSortOrder.None)  
        
                {  
        
                    RadSortOrder sort = uxTourGrid.Columns[0].SortOrder;  
        
                    uxTourGrid.Columns[0].SortOrder = RadSortOrder.None;  
        
                    uxTourGrid.Columns[0].SortOrder = sort;  
        
                }  
        
            }

I'm sorting according to first column.

Thanks for any help.

Regards,
Daniel

RadTimePicker in RadGridView

I have 4 DateTime Fields in my RadGridView. StartDate, StartTime, EndTime, EndDate. I need to be able to have a Time only picker when adding / editing in the grid. I can't seem to find a way to use the RadTimePicker. Is there a way to integrate this? Or use the GridViewDateTimeColumn in such a manner?

I'm Using WinForms Q1 2012 (2012.1.12.215) in a .NET 4.0 framework project.

Thanks. Matthew

Setting the font details for ALL controls

Hi,

Is there a way to set the font details (say, to Arial 9.35) for ALL controls in a single place or do I need to set them all individually?

If I can do it programmtically that'd be great as that will allow me to let the users choose their font.

Best way to set the location for RadGridView ColumnChooser dialog box

Hi,

What's the intended/best way of setting the location for RadGridView's ColumnChooser dialog box? I want to show it at the center of the calling application (ideally) or at least within the bounds of the calling application.

I tried using ColumnChooser.StartPosition = FormStartPosition.CenterParent but it didn't work. May be because its Parent or MdiParent is set to NULL (I found this while debugging).

Thus currently I am setting the DesktopLocation property of ColumnChooser to the DesktopLocation of ParentForm offset by (50, 50).

//Since workListRadGridView.ColumnChooser's Parent or MdiParent property is not set,

//setting its StartPosition to FormStartPosition.CenterParent doesn't work.

//As a workaround, get parent form's desktop location and offset it 50 pixels from

//both X and Y co-ordinates to keep the column chooser within the bounds of the application.

//Parent form desktop location.

//DesktopLocation property is idle choice because of the following remark in its documentation on MSDN:

//"If your application is running on a multimonitor system, the coordinates of the form are the coordinates for the combined desktop."

//http://msdn.microsoft.com/en-us/library/system.windows.forms.form.desktoplocation(v=vs.100).aspx

//Telerik's documentation for ColumnChooser also has the mention for DesktopLocation property.

//(though not in the context of "setting the location")

//http://www.telerik.com/help/winforms/gridview-columns-working-with-column-chooser.html

if (this.ParentForm != null

&& this.ParentForm.DesktopLocation != null)

{

Point columnChooserDesktopLocation = new Point(this.ParentForm.DesktopLocation.X, this.ParentForm.DesktopLocation.Y);

columnChooserDesktopLocation.Offset(50, 50);

radGridView.ColumnChooser.DesktopLocation = columnChooserDesktopLocation;

}

But I am bit apprehensive of ParentForm being NULL or this approach not working correctly for some reason. Thus needed to know if there exists a better way of specifying the location of the ColumnChooser.

Also, more importantly, I want the above code to work even if the user has more than one monitor/display unit.

Thanks,
~Abhay

Trying to use RadDock

Hi guys,

I'm having a little trouble trying to get the RadDock working.

Here is my scenario:
I have a windows form which contains a RadPageView. Inside one of those tabs I have multiple RadSplitContainers which are giving me left, center, right and bottom panels. The left, right and bottom ones are fixed with the center expanding with the form/window. In each of these I need to house UserControls or Forms.

But how?

I've dropped a RadDock into a panel and set it to fill the parent. I've then created both a UserControl and a Form which at run time (Form1_Load) either one gets inserted into the RadDock. Something like this (ucBBMain is my UserControl):

UserControl uc = new ucBBMain();
radDock1.DockControl(uc, DockPosition.Fill);

But I get an error:
"Invalid DockTabStrip for a DockPosition.Fill operation."

I also tried this but get the same error:
UserControl uc = new ucBBMain();
HostWindow host = new HostWindow(uc, DockType.Document);
radDock1.DockControl(host, DockPosition.Fill);

Very same happens with a Form.

So how can I put UserControls or Forms into a RadDock where their size is expanded to the RadDock they are inside?

Or in fact is a RadDock the correct control to use? Can I put a UserControl directly into the SplitContainer panels?

Titlebar Hidden by PageView

Hi,

I'm using a ShapedForm that has a PageView in it. When I set the PageView to Dock Fill, it covers the TitleBar completely.

How can I have the PageView just fill the form but not the TitleBar?

Thanks.

Properties are not saved

We are facing several problems when persisting properties changed at design time. Sometimes with no apparent reason the properties changes are not saved to disk nor showed at run time.
It happens with radtreeview, radmenu, radmaskededit.
Working with imagelist in radtreeview is a nightmare. Changing fonts in radmenu does not work anymore. ExcludePromptsandLiterals works in one machine but not in the other.
Theses problems are driving us insane, since it happens in different projects and different machines.
These machines are running windows 7 and visual studio 2010.
I just can´t believe simple things like these do not work properly. I would like to hear from you what could possibly be happening.
