Dropdown selection not activated with mouse button up

Hello, I am experiencing a basic problem with Telerik controls concerning when the mouse down is performed on one part of the control, and the mouse up occurs on another part of the control. The item is not selected in that case.

For example, in the case of the RadCombobox, if I click the mouse button over the drop down arrow, the combobox opens. Without releasing the mouse button, I move the cursor over an item in the drop down, and then release the button.

Expected behavior: the item would be selected and placed into the edit box portion of the combobox.

Actual behavior: the item is not selected; the drop down remains open, and I must push and release the mouse button on the desired item to select it.

This happens no matter how I set the ClickMode property.

Another example is in RadMenuStrip. If I have a simple menu:

File
Exit

and I click over File, it drops down the menu to show the Exit item. Without releasing the button, I highlight Exit and release the button.

Expected Behavior: The Exit menu item's click event is fired.
Actual Behavior: It is not fired. I have to click Exit and release mouse button again to select it.

I don't understand why this is the default behavior when normal Windows apps have been doing it my way for decades? FWIW, the DevExpress menus work exactly the same way as yours, so I'm thinking there is a fundamental change of thinking with control developers! ;)

Thanks,
David

When closing Property Builder it locks up VS2008

When I close the property builder Visual Studio is prety much locked up. When I try to kill the process it then tells me that there is still a modal dialog open. If there is it is not visable. This seems to be intermitant. One other thing. I have had on ocasion where when adding columns to a databound grid it will throw an error that the data memeber value that was entered does not exist then the window disapears.

[Solved] RadTabStrip prohibits Form.AcceptButton?

Hello,

I'm using a RadTabStrip in a form where I want to contain settings. When the user has clicked around in the different tabs and made his settings I want him to be able to press 'Enter' and make the settings dialogue dissappear. My problem is that even though the AcceptButton-property is set to my OK button, it seems that nothing happens if my RadTabStripItem is focused. This means that if I click a new tab, pressing enter does nothing (pressing esc for cancel still works fine). Is there any good work around for this?

grouping question

Hi there,
I want to programmatically add grouping to my datagrid like so:

    
            radGridView1.MasterGridViewTemplate.GroupByExpressions.Add("[PeriodeID] Group By [PeriodeID]");

When I run this the datagrid isn't grouped by the column, only sorted by the column.
When I drag and drop the column the datagrid does get a proper grouping header.
What am i missing?

Tanx!

[Solved] Cursor Change on RadLabelElement within RadGridView GridViewCommandColumn

Hi Guys,

I am having a problem changing the Cursor icon to a hand while hovering or entering over a RadLabelElement within the RadGridView GridViewCommandColumn cell. I am using the most current version of the controls.

The following is how my controls are placed:

I have a RadGridView control, with a GridViewCommandColumn that contains a RadMenuElement and 4 RadLabelElements.

My problem arises when I try to use the MouseEnter() event handler on the RadLabelElement to change the Cursor type from the default (arrow) to a Hand. It will not make the change.

The following is an outline of the source code that contains the problems described above:

    
              private void gvManageDocs_CellFormatting(object sender, CellFormattingEventArgs e)    
        
                        {  
        
                                if (e.CellElement is GridCommandCellElement)  
        
                                {  
        
                                        GridViewRowInfo gvrRow = e.CellElement.RowInfo;  
        
                                        e.CellElement.Children.Clear();  
        
                                        RadMenuElement buttonElement = new RadMenuElement();  
        
                                        RadLabelElement lblLabel = new RadLabelElement();  
        
                                        lblLabel.Text = "View";  
        
                                        lblLabel.Click += new EventHandler(lblView_Click);  
        
                                        lblLabel.MouseLeave += new EventHandler(lblLabel_MouseLeave);                                  
        
                                        lblLabel.MouseEnter += new EventHandler(lblLabel_MouseEnter);  
        
                                        lblLabel.ForeColor = Color.Blue;  
        
                                        buttonElement.Items.Add(lblLabel);  
        
                                        lblLabel = null;  
        
                                        lblLabel = new RadLabelElement();  
        
                                        lblLabel.Text = "Modify";  
        
                                        lblLabel.Click += new EventHandler(lblModify_Click);  
        
                                        lblLabel.MouseLeave += new EventHandler(lblLabel_MouseLeave);  
        
                                        lblLabel.MouseEnter += new EventHandler(lblLabel_MouseEnter);  
        
                                        lblLabel.ForeColor = Color.Blue;  
        
                                        buttonElement.Items.Add(lblLabel);  
        
                                        lblLabel = null;  
        
                                        }          
        
                                        e.CellElement.Children.Add(buttonElement);  
        
                                }  
        
            void lblLabel_MouseEnter(object sender, EventArgs e)  
        
                    {  
        
                           Cursor = Cursors.Hand;  
        
                           ((RadLabelElement)sender).ForeColor  = Color.Red;  
        
                   }  
        
            void lblLabel_MouseLeave(object sender, EventArgs e)  
        
                    {  
        
                        Cursor = Cursors.Arrow;  
        
                        ((RadLabelElement)sender).ForeColor = Color.Blue;              
        
                    }

Please let me know what I can do to solve this issue.

Many thanks,

[Solved] AllowEdit linked to obsolete LabelEdit

Hi,

Whenever I change the AllowEdit property your obsolete LabelEdit property gets added to my Designer and I receive a warning on compile. I then have to go and manually remove it again. This is probably because when I change AllowEdit the LabelEdit changes with it in the controls designer properties.

Though not critical it is annoying..

Regards,
Brad
