Hi!

I'm trying to to a master-detail view inside a gridview from my own objects but can't get it working ...
trying a details into master object approach only the first item has children , so tryed a object list with parent items and another object list with children items and made a relation inside gridview object but then none of the items have children in the grid ...

Can you help me please?

I've found in this forum about hierachical items from objects not working on jan'07 but the answer from telerik is that it will be solved in q2 release and i'm trying the q3 release , it's possible it's not implemented yet?

thanks

Strange MaskedEditBox drag-and-drop behavior

I have a MaskedEditBox set up to allow drag-and-drop, and I've encountered what I must believe is a bug of some sort.

The control is set up with a mask for a standard North American phone number -- (###) ###-#### -- and during the DragEnter event I compare the drag data to a regex that confirms it has a phone number in it. In the DragDrop event, I have the following code:

    
                    private void txtConnectToPhone_DragDrop(object sender, DragEventArgs e) 
        
                    { 
        
                        Match dropPhone = phoneRegex.Match(e.Data.GetData(typeof(string)).ToString()); 
        
                        if (dropPhone.Success) 
        
                            txtConnectToPhone.Value = dropPhone.Value.RemoveNonNumeric();    
        
                    }

You can ignore the "RemoveNonNumeric()" method -- that's an extension method I have created for the string class.

It works fine unless I have a subset of the control's text selected or the cursor positioned somewhere in the middle of the text. For example, let's assume the control displays "(800) 555-1212" and I select the "555" portion of the string or position the cursor in front of the first 5. If I were to drag text containing "8135551212" into the control, it would display "(800) 813-5551" indicating that it's inserting the dragged text at the point of the selection.

The only way to get this behavior not to happen is to set the value to "" prior to setting it to the new number. I can't imagine why this behavior would be by design.

RightToLeft

I have to display a couple of charts in both left to right (LTR) and right to left (RTL) orientations, depending on the CurrentUICulture. It seems the chart doesn't support this.

My current solution is to use code to move around the elements on the chart based on the culture. Here's the code I'm using:

    
            private void LocalizeChart(RadChart chart) 
        
            { 
        
                bool isRtl = RightToLeft == RightToLeft.Yes; 
        
                chart.Legend.Appearance.Position.AlignedPosition = isRtl ? AlignedPositions.Right : AlignedPositions.Left; 
        
                chart.PlotArea.YAxis.Visible = isRtl ? ChartAxisVisibility.True : ChartAxisVisibility.False; 
        
                chart.PlotArea.YAxis2.Visible = isRtl ? ChartAxisVisibility.False : ChartAxisVisibility.True; 
        
                chart.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = CHART_X_AXIS_TEXT_ANGLE * (isRtl ? 1 : -1); 
        
            }

This solves some of the display issues, but I couldn't find any easy way to cause the charts to appear in the "top left" quadrant so the values on the x-axis "increase" from right to left. The alignments should automatically "reverse" direction in RTL mode.

Actually, I think there should be a property to specify whether a chart should stick to mathematical quadrants for the plot area, or to standard control alignment and direction. Not all charts show pure mathematical data.

Is there any way currently to get the chart to reverse the x-axis direction?

Thanks for any assistance!

Unable to load the "Telerik.WinControls.GridView" into Tool Box of VS .Net 2005

Hi,
We have purchased the Telirik Rad controls for winformsQ1 2008.
After installing that,we got all controls popped into the Tool Box automatically,
except "Rad Grid View".I have tried to get Rad Grid View control into ToolBox manually by "Choose Items" then adding the DLL,"Telerik.WinControls.GridView.dll" in the C:\ProgramFiles\Telerik\Rad controls for winforms Q1 2008\bin.
It is throwing an Exception/Error Message Box saying
"There was an Error loading types from Assembly "C:\ProgramFiles\Telerik\Rad controls for winforms Q1 2008\bin\Telerik.WinControls.GridView.dll" Could not load type 'System.ComponentModel.PropertyChangingEventArgs' from Assembly 'System,version=2.0.0.0,culture= neutral'"

Labeling Axes on radChart

Hi,

I'm having some trouble quickly figuring out how to place the ticks on a radchart.

I need to plot realtime data (temperature against time) on a line chart. The data required the series orientation to be flipped to the Y Axis. Since I've changed the series orientation I don't get the minor tick. I'm sampling 4 readings a second. The chart should contain data worth 17 minutes.

I would like to the ticks to be per minute (4 readings *16 seconds), but the ticks are showing up per reading.

I would like to give a user zoom in/out capability for the data. I need to label the ticks correctly.

If anyone could point me to some samples or more detailed documentation on labeling the X and Y axis I would really appreciate it.

[Solved] radgrid disabled setting problems

I created a radgrid that gets refreshed every 2 seconds with new data.

I noticed that if the user is resizing a column during the refresh it causes an error.

To stop this from happening, before the refresh takes place I set the grid.enabled = false. This solves that problem, but, everytime the data is refreshed, it seems the grid flashes a quick gray overlay color. I can still see the data but there is just a flash of gray.

How can I get rid of this grey color? I dont want any visual changes when the grid is not enabled?

If there is a better way around the problem of the grid resize on datasource update then please also let me know!!

Grid reverting to default theme.

I am using Q1 2008 and am creating my grids entirely in code due to the Visual Studio designer crash bug (which is really not that big of deal as it is probably better form anyway - no pun intended).

But I am running into a small problem. In my code I create a grid like this:

    
            _rgvRequests = new RadGridView();  
        
            _rgvRequests.Dock = DockStyle.Fill;  
        
            _rgvRequests.ThemeName = "Telerik"; 

            Other grid initialization code here...

This works fine on the first grid that is opened, but all forms (completely unrelated to the first) opened after the first, that have a grid on them, set that grid to the default theme (dark header, dark sand background).

I do use a some static helper methods on a utility class to create the grid rows but I do not believe this is causing a problem.

Has anyone else seen this?

Thanks,

Justin

Localised 'AddNewRowString' in Grid not showing correctly.

Hi,

The localised string is not shown, instead the english version "Click here to add a new row". After clicking on the new row it changes to the correct String "(Neue Zeile)".
This only happens with the AddNewRowString , all others are displayed in German from the beginning.

I wrote my own RadGridLocalizationProvider (for german) and use this code

Public Class RadGridLokalisierungDeutsch
    Inherits RadGridLocalizationProvider
    Public Overloads Overrides Function GetLocalizedString(ByVal id As String) As String
        Select Case id
            Case RadGridStringId.AddNewRowString
                Return "(Neue Zeile)"
           ... ' More cases
            Case Else
                Return MyBase.GetLocalizedString(id)
        End Select
    End Function
End Class

I am guessing this is a bug ? Can you please look into it ?

Thanks in general for the great support, you have always been very helpful.

Regards
