Hi,

I am trying to get the correct row from my grid for the Event RadGridView1.DragDrop.

In http://www.telerik.com/community/forums/thread/b311D-baegte.aspx#410155 you advised to use the GetElementAtPoint method, which is exactly what I need. Has this been removed in Q1_2008 ? Whats the correct way to get a Row by mousecoordinates?

My code looks like this

    
                Private Sub RadGridView1_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles RadGridView1.DragDrop 
        
                    If e.Data.GetDataPresent(GetType(Resource)) Then 
        
                        Dim draggedResource As Resource = CType(e.Data.GetData(GetType(Resource)), Resource) 
        
                        ' GetElementAtPoint does not exist 
        
                        ' Dim target As RadElement = RadGridView1.GetElementAtPoint(New System.Drawing.Point(e.X, e.Y)) 
        
                    End If 
        
                End Sub

RadCombobox KeyBoard

Hi everyone, I'm curently writing a 100% keyboard application (of course you can use the mouse too but it's faster when you use the keyoard only) . My prolem is when I have more than 1 result to a query I need too show the result and let the user choice which one he want to use... But I use the SelectedItemChange Event to set something else. So when the user use the keyDown to move in the combobox that call the SelectedItemChange Event but I don't want this. With the VS Combobox I setted a boolean to true when the user pressed the keydown , but in the RadCombobox the keydown event comes before the SelectedItemChange Event so my way is impossible. If you can just show me an other way I would be happy.

Thanks and sorry for all english mistakes

Textbox ignores SHIFT+TAB

SORRY - I found this is addressed in another Thread.

Hi,

while TAB (next control in tab order) works on RadTextBox -
SHIFT-TAB (prev control in tab order) does not work.

Replaceing RadTextBox with Forms.Textbox makes SHIFT-TAB work.
So I guess it is a problem with RadTextBox.

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

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.
