I am using the Q1 2008 beta. I have the following issues while using the grid with hierarchical on. I have 2 dataviews on the gridViewTemplate2.DataSource = dvPrior; grdPersonal.MasterGridViewTemplate.DataSource = dvPersonal;

Issues:
1) If I rebind the grid w/ the parent expanded, the parent disappears and the child records only show. If I sort it comes back, but if I click the + sign it will sometime crash. See error

System.NullReferenceException: Object reference not set to an instance of an object. at Telerik.WinControls.UI.GridRowElement.UpdateInfo() at Telerik.WinControls.UI.GridTableElement.Update(GridUINotifyAction action, GridViewRowInfo[] rowInfos) at Telerik.WinControls.UI.RadGridView.set_CurrentView(IGridView value) at Telerik.WinControls.UI.BaseGridBehavior.SetCurrentView(MouseEventArgs e) at Telerik.WinControls.UI.BaseGridBehavior.OnMouseDownLeft(MouseEventArgs e) at Telerik.WinControls.UI.BaseGridBehavior.OnMouseDown(MouseEventArgs e) at Telerik.WinControls.UI.RadGridView.OnMouseDown(MouseEventArgs e) at System.Windows.Forms.Control.WmMouseDown(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at Telerik.WinControls.RadControl.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at

2) I can't seem to create a relationship between the parent and child with more then 1 column. If I add 2 members it errors and says that a relationship already exists. If I add 2 columns in the child and parent the application crashes when I iniialize the control.

3) Speed of the hierarchical is pretty slow to first load. I have a 400 record table for child dataview and 20 record table for parent dataview and it takes ~ 20 seconds to load with the relation on 1 column. In comparison; the parent w/o the hierarchical children loads in 1 sec or less.

4) It would be nice to NOT show the + sign if there are no children or have that option to turn that feature on or off. Can this be an option?

5) There doesn't seem to be a way to control the height of the expanded out rows. If there is only 1 child row the expanded panel seems to be large. Will there be a way to autosize to the end of the last row and/or set the default height?

6) I have a hierarchical grid w/ 2 parent records. If I expand out the last parent record in the grid and then click the + to collapse it doesn't collapse and the parent disappears. If I re-sort the 2 parent records so that the orignial expanded record is not the last and expand and collapse the function works perfectly. Seems to only happen when parent record is the last in the grid.

It would be nice to get weekly or biweekly beta updates so us users could work out some of the bugs before release.

Default Sort Arrow

Hi,

I'm trying to set a default sort on a telerik gridview (Q2 2007)

    
            BindingList<Temp> tempList = new BindingList<Temp>(); 
        
            int j = 0; 
        
            for (int i = 1000; i > 0; i--) 
        
            { 
        
                 Temp temp = new Temp(); 
        
                 temp.Temp1 = i + " descending"; 
        
                 temp.Temp2 = j + " ascending"; 
        
                 tempList.Add(temp); 
        
                 j ++; 
        
            } 
        
            radGridView1.MasterGridViewTemplate 
        
                .SortExpressions.Add("Temp1", RadSortOrder.Ascending); 
        
            bindingSource1.DataSource = tempList;

The sort appears to work, however, the arrow to indicate sorting is does not show. Is there something that I can do to add this, or is the functionality non-existent?

Thanks,

David

RadTitleBar Buttons Keep Hover Images Displayed

I am running Q1 2008 SP1 of the WinForm Controls. I have created a custom theme for the RadTitleBar. The theme also includes 6 custom images for the Min, Max, and Close buttons. Three imaged for the default and 3 for mouse over, he mouse over works great for all three buttons. The problem I am having is that if I click on the “Minimized” button the form will be minimize to the task bar, when I bring the form back up the “Minimized” button is showing the mouse over image. This also happens on the max button.

I did notice the same problem in the Telerik Style Builder. If any anyone can point me in the correct direction on how to fix this please let me know. Thanks in advance!

This is how I have my images set UI Editor:

Telerik.Wincontrols.UI.RadImageButtonElement

                Image: Selected File Image1
                ImageClicked: Selected File Image 1
                ImageHovered: Selected File Image 2

Hidden userdockforms repainted

Docking 2008 Q1 SP1

In some strange cases opening a new document seems to cause repeated repainting / resizing(?) of documents that are in the background. Are there known repainting/refresh bugs? To provide a test application is probably quite complicated. I've noticed this mainly with UserDockForms that contain nested Table Layout Panels and .net UserControls.

Refreshing the chart will not showing the X-axis lables

hi,

I have drawn the Gantt chart with date on X-axis, time on Y-axis.
I have added the range of the X-Axis using the following Statement

radChart1.PlotArea.XAxis.AddRange(GraphStartTime.ToOADate(), GraphStartTime.AddDays(7).ToOADate(), 1);

I have set the Y-AxisLabel text to "XYZ".

My requirement is to change the AxisLabel text to "ABC", when the user clicks on the button.

I add the following code:
private void btnChangeAxisLabel_Click(object sender, EventArgs e)
{
            radChart1.PlotArea.YAxis.AxisLabel.TextBlock.Text = "XYZ";
            radChart1.Refresh();
            radChart1.UpdateGraphics();
            radChart1.Update();
}

It is changing the AxisLabel text to "ABC".
But X-Axis ChartAxisItem's TextBlock.Text is not appearing(i.e The dates what i have added to X-axis is not appearing).

Please share the sample code.

Chart (obsolete as of Q1 2013)

Using Objects as Datasources

I've recently started using DevForce for middle-tier development on my winform applications and am having difficulty binding with the Telerik GridView. I saw in the example the grid binds to arraylists but what about Generic Collections? The grid binds to all properties and I don't see a way to control that. Am I missing something?

VisbileChanged Event fired at DesignTime?

Hello,

I am having problems with the docking manager (6.0.2.0) at Design time again.

One of the Panels I am using in the docking manager has a Handler for the VisibleChanged-Event (so it fills its components with data the first time its actually visible)

This caused the visual studio designer (!!) to freeze (CPU 100%).
When I comment out the VisibleChanged Handler of the Panel , everything works fine.

At runtime both alternatives work.

So do events actually get fired at design time ?

Which DockPanel-Event should I handle if I want to intialize components (for example fill a RadComboBox with data) at runtime when they are first visible to the user.

Greetings

Dock
