Is there a way to know when a user is dragging a RadTitleBar around?

I tried to have a ShapedForm with a RadTitleBar, and catch the events in the MouseDown and MouseUp events for the titlebar with the following :

    
            private void radTitleBar1_MouseDown(object sender, MouseEventArgs e)  
        
            {  
        
                if (e.Button == MouseButtons.Left)  
        
                {  
        
                    txtTest.Text = "Down";  
        
                }  
        
            }  
        
            private void radTitleBar1_MouseUp(object sender, MouseEventArgs e)  
        
            {  
        
                if (e.Button == MouseButtons.Left)  
        
                {  
        
                    txtTest.Text = "Up";  
        
                }  
        
            }

The problem is that I don't always get the MouseUp event. I get the event about once every 20 times I tried it. Is there a problem with the mouseup event, or is there another way I can get the info about the start/stop of dragging a form around?

Tooltip on row

Hi guys,

is it possible to show a tooltip for each row in a RadGridview?
I found some solution for a MS DatagridView, but that one uses HittestInfo which is not supported by the Radgridview...

Thanks,

Ben

Dysfunctional IDE Control

Hi all,

In accordance with RadChart documentation, I am attempting to connect to an XML datasource, and cannot.

My process:

See Documentation --> Contents tab --> Getting Started --> Quick Start: Create A Data bound Chart, and scroll down the right window pane to "Configuring the Data Source". An image displays the user's mouse selecting <New Data Source...>, but that option does not exist in my configuration. Also, in the following documentation image (Data Source Configuration Wizard ), I only have options for database, web service and object, but not XML file.

Please recommend a fix.

Also, i am seeking a demo for a multi-line winForm line chart, and cannot find one. Can you kindly recommend one?

Thank you.

Jeff

Assigning DateTime array to datasource

Hi,

I am having a small problem with the RadComboBox. I am assigning a DateTime array as datasource to a combobox, and when I get a SelectedIndexChanged event I'd like to get the selected object out again (pretty much so I can use the RadComboBox as a drop-in replacement for standard .net combobox). However, I am unable to get the object, as the SelectedValue is null, and since I use an array I can't set the ValueMember. Is there a way to accomplish this?

The workaround I am using at the moment is this:

    
                    private void drdDate_SelectedIndexChanged(object sender, EventArgs e)  
        
                    {  
        
                        if (drdDate.SelectedIndex >= 0)  
        
                        {  
        
                            DateTime tstTime;  
        
                            if (DateTime.TryParse(((RadComboBoxItem)drdDate.SelectedItem).Text, out tstTime))  
        
                            {  
        
                                // do the processing here   
        
                            }  
        
                        }  
        
                    }

But I am really hoping I don't have to do text parsing for all the different comboboxes in the application.

Theme Not Being Applied to GridView

I cannot get a custom theme to apply to a gridview. I can get it to work on buttons, panels, tabstrips, trees. I follow the same steps but the visual styles are not reflected when my application runs.

I create a brand new grid.
I set both scrollbars to visible.
I create a new theme and change the fills so the are obviously red. The preview reflects this.
I save the theme to a file.
I use my thememanager to load the theme.
I open the smart tag on the new gridview and choose my new theme.
I run the application and none of the changes are visible.

I go back to the smart tag, check the theme and it is set properly. If i debug the form_load event, the style of my control is not empty. I go to the smart tag and Edit UI Elements and the colors of my scroll bars are visible. It almost feels like something is coming in at the last moment and resetting the theme although there is no code to do so.

Like i said, i have been able to get other radelements to use custom themes without problem but the grid doesn't seem to be functioning the same way.

Apply Theme to RadButtonElement

I posted earlier about issues with the CommandButton and your suggestion of "hiding" the existing button and creating a new one has worked well and cleared up a number of issues. Now, i would like to apply a theme to the button i have inserted, but am unable to do so to a RadButtonElement and i can't add a RadButton (which can have a theme applied) to the cell. How can i set the theme for this button or other buttons in the grid? If i cant, how can i set the appearance for the different states of the button (isPressed,isMouseOver, etc) like i can using the visual design tools? Can those be set through code? Thanks for your help!
