I have a Radmenu that I use to switch between different views on my spreadsheet control.

My click event will call a method to flip the active sheet on my spreadsheet control and then set the focus to that control.

The odd thing is that if I physically click the menu item, the focus will move to my spreadsheet control and then immediately go back to the menu item. But if I use the keyboard and press "space" on the menu item, the focus will remain on the spreadsheet control (as expected).

I tested this with a sample app that has a radmenu with 2 items, and two buttons. Each menu item will set the focus to a button. Each button has a Enter and Leave event that updates the text of the button. The behaviour I'm noticing is replicated in this project.

    
                public partial class Form1 : Form  
        
                {  
        
                    public Form1()  
        
                    {  
        
                        InitializeComponent();  
        
                    }  
        
                    private void button1_Enter(object sender, EventArgs e)  
        
                    {  
        
                        button1.Text = "got focus";  
        
                    }  
        
                    private void button1_Leave(object sender, EventArgs e)  
        
                    {  
        
                        button1.Text = "lost focus";  
        
                    }  
        
                    private void radMenuItem1_Click(object sender, EventArgs e)  
        
                    {  
        
                        button1.Focus();  
        
                    }  
        
                    private void radMenuItem2_Click(object sender, EventArgs e)  
        
                    {  
        
                        button2.Focus();  
        
                    }  
        
                    private void button2_Enter(object sender, EventArgs e)  
        
                    {  
        
                        button2.Text = "got focus";  
        
                    }  
        
                    private void button2_Leave(object sender, EventArgs e)  
        
                    {  
        
                        button2.Text = "lost focus";  
        
                    }

Hierarchical grid summarize totals of child tables

Hi, I just don't know where to start, so I turn to you.

I need to bind a grid to hierarchical data. Which goes to three nested levels deep. On every level I need to summarize the totals of the childtables. It more like a tree view of the dataset including totals for rows.

So on the highest level I would see the totals of all childtables.

My guess would be that I add a custom row at the end of each childtable in the view which would hold the totals of the childtables.

I should also be possible to export this grid to Excell. would that be a problem, concerning the custom added total rows?

Hope you can point me in the right direction.

Thanks

ComboBoxColumn Filter display?

I am using a ComboBoxColumn in my grid, and also allowing filtering on that column. My ComboBoxColumn uses the DisplayMember and ValueMember settings to show the correct text in the cells, which all works very well.

However, when the user sets a filter on the column, such as "Equal to", they are able to select a value from a dropdownlist, which is great, but after selecting a value, the filter display reverts to the numeric value of their choice, instead of using the DisplayName property to display the corresponding text. Is there a way to display the DisplayName value in the filter cell?

Thanks,

Rachel

Problem with Text Format

Hi,

I need to use this mask '##0.#'
So if I launch my application it will display '___._'. That's correct.

The problem is when I change the Value.

By default : (on debug)
  this.RadMaskedEditBox_Test.Mask "##0.#" string
  this.RadMaskedEditBox_Test.Value "" object {string}
  this.RadMaskedEditBox_Test.Text "___._" string

Value to set :
  Singleton.Instance.MarketGrowthRate 1.4 decimal

    
            this.RadMaskedEditBox_Test.Value = Singleton.Instance.MarketGrowthRate.ToString(this.RadMaskedEditBox_Test.Mask);

After this code :
this.RadMaskedEditBox_Test.Value "14" object {string}
this.RadMaskedEditBox_Test.Text "14_._" string
It doesn't set 1.4 in the value and "__1.4" in the text.

And I can't use something like n1 because I must have a maxlength. (999.9)

Thanks for your help

QuickAccessToolbar question

Hi.
Can you tell me how can I change the title of menu entries that shows up when a user clicks on a QuickAccessToolbar drop-down arrow, on the right of the toolbar?
I would like to translate them from English to some other language(s).

So that, depending on the language settings, it won't show "Show Below the Ribbon" and "Minimize the Ribbon".

I'm using VS2005 Pro and Q2 2008 SP1.

*** EDIT: I just figured it out.
Here:

RadRibbonBar1.LocalizationSettings.MaximizeRibbonItemText = "Some Text Here..."

Thanks.

[Solved] Theme to all controls (besides ControlDefault)

Hi!

Some where long the line, I've read that the Q3 release of winforms would have a common theme to all controls, besides the ControlDefault one.

My question is how, if so, has this been implemented? All the themes available have properties to work on every control?
