Boolean checkbox column and 3 clicks to edit.

I have a grid view that is bound to a boolean data type. This produces a checkbox in every row. I want this checkbox to be editable and it works. However, the users do not like the fact that they must first, click on a row, then click on the checkbox cell to get it into edit mode and then click on it to change the value in the checkbox. Is there anyway to reduce this down to Select the row and then click the checkbox, in other words once I select a row, is there some code I can use to automatically place this column into edit mode?

Update TextBox.Text without firing an event

Hello!

Is it possible to change TextBox.Text value programmatically without firing "TextChanging" event?
I'm looking for something like

    
            textBox.BeginUpdate(); 
        
            textBox.Text = "Leave no tracks behind"; 
        
            textBox.EndUpdate();

Best regards, Yury Babaev.

Vertical scrollbar doesn’t appear in ToolWindow

Good morning.

Regarding this problem, I tried to use your new RadControls for WinForms Q1 2010. If you try with the same test project as above, you will notice that the vertical scrollbar doesn’t appear, as before. The only improvement is that now, when you click on a groupitem, the vertical scrollbar appears and doesn’t disappear anymore, but when you programmatically add groupitems to the radPanelBar, again no vertical scrollbar is displayed. Any suggestion? Thank you very much.

Confusing Themes behavior

I'm using RadControls for WinForms Q3 2009 SP1, and I'm running Windows XP.

I've dropped a RadTabStrip and a RadListBox onto a simple form. I've added sample items to the RadListBox and a few sample tabs to the RadTabStrip . Both controls are set to use the ControlDefault Theme.

When the form is displayed, I can select an item in the RadListBox and it is highlighted. If I drag the mouse over the other items, these too become highlighted. There is no way to distinguish the 'selected' item visually. If I pass the mouse back over the list items, the highlighting changes; even so, it would confuse me as a user. The RadListBox still seems to have multiple items selected.

The RadTabStrip exhibits similar behavior. I can select a Tab and it will be highlighted. If I select another Tab, the original Tab still appears highlighted, unless I drag the mouse over it.

I'm aware that I can modify this behavior using VisualStyleBuilder. But my gut feeling is that I'm missing something; I'm wondering if I'm the only one who thinks the default behavior is odd. Is this something that looks and acts differently in different contexts (e.g. the app running in Vista or something)?

Regards,
John

Missing properties of web treeview

Hi ! I hope this post will have its place here...

I realised a tree view in asp.net, and now I need to do the same for a winform... the matter is that there aren't the same properties.

For example I am using these methods in the asp version :

    
            private void Filter() 
        
                    { 
        
                        try 
        
                        { 
        
                            LoadAllNodes(); 
        
                            if (accountTextBox.Text.TrimEnd().Equals("*") || string.IsNullOrEmpty(accountTextBox.Text.TrimEnd())) 
        
                                return; 
        
                            //Get all nodes matching the filter 
        
                            List<RadTreeNode> matchingNodes = new List<RadTreeNode>(); 
        
                            IList<RadTreeNode> nodesToFilter = ((List<RadTreeNode>)radTreeView.GetAllNodes()).FindAll(delegate(RadTreeNode rdTNode) { return rdTNode.Tag.Equals("Account"); }); 
        
                            for (int i = 0; i < nodesToFilter.Count; i++) 
        
                            { 
        
                                if (nodesToFilter[i].Text.StartsWith(accountTextBox.Text.TrimEnd(), StringComparison.OrdinalIgnoreCase)) 
        
                                    matchingNodes.Add(nodesToFilter[i]); 
        
                            } 
        
                            IList<RadTreeNode> allNodes = radTreeView.GetAllNodes(); 
        
                            for (int i = 0; i < allNodes.Count; i++) 
        
                            { 
        
                                if (IsToFilter(allNodes[i], matchingNodes)) 
        
                                    allNodes[i].Remove(); 
        
                            } 
        
                        } 
        
                        catch (Exception ex) 
        
                        { 
        
                            throw ex; 
        
                        } 
        
                    }

    
            private bool IsToFilter(RadTreeNode radTreeNode, List<RadTreeNode> matchingNodes) 
        
                    { 
        
                        if (radTreeNode.Text.StartsWith(accountTextBox.Text.TrimEnd(), StringComparison.OrdinalIgnoreCase)) 
        
                            return false; 
        
                        foreach (RadTreeNode item in matchingNodes) 
        
                        { 
        
                            if (radTreeNode.IsAncestorOf(item)) 
        
                                return false; 
        
                        } 
        
                        return true; 
        
                    }

But for winform version there is no method "GetAllNodes()" for RadTreeView, and I have the same problem with "IsAncestorOf".

Could you help me and explain me which property/metho I can use without changing all my code ?

Thanks a lot !

Displaying selected appointment problem.

Me Again!!

I don't know if i'm doing something wrong, or if this is a bug.

I am trying to make my scheduler only show a given appointment.

I wanted to display the hour before and after the appointment. To do so I am using this code:

                    private void showAppointment(DateTime dt1)         
            {         
                        rsAppointments.ActiveView.StartDate = Convert.ToDateTime(dt1.ToShortDateString());         
                        ((SchedulerDayView)rsAppointments.ActiveView).RulerStartScale = dt1.Hour - 1;         
                        ((SchedulerDayView)rsAppointments.ActiveView).RulerEndScale = dt1.AddMinutes(Convert.ToDouble(appointDuration)).Hour + 1;         
            }         

It works fine the first time its called, however after its been called a few times, it starts showing more and more time and will show the 3-6 hours before the appointment.

Any suggestions?

Thanks!
