Format GroupByExpessions Sum Total

Hello Again

Using

.MasterGridViewTemplate.GroupByExpressions.Add("Application,sum(Score) As [Sub Total Score = ] Group By Application")

which works fine but on multiple applicaion rows is really messy, is there a way to format the heading to create an easy to read column, so instead of something that looks like this;

app1firstappname;Sub Total Score = 2
app2secondappname;Sub Total Score = 3
app2thirdappname;Sub Total Score = 3

it would more look like this

app1firstappname;                                        Sub Total Score = 2
app2secondappname;                                   Sub Total Score = 3
app2thirdappname;                                       Sub Total Score = 3

Cheers

theme/style builder constantly crashing

I am having real grief with the Telerik theme/style builder app for winforms. It's pretty much constantly crashing.

For example, I have my apps RADMenuStrip selected, clicked the Tasks arrow and selected 'Open Theme Builder',
splash screen comes up and I get a pretty long error popping up that starts with:
'System.ArgumentException: No such property registered: HotTracking, Telerik.WinControls.UI.GridRowElement at....' (and it carries on for around 30 more lines - see this link for a screenshot ).
When I click okay, the splash screen stays there, but the app has totally hung. I then have to kill the 'splashform' app using Task Manager, which in turn also closes Visual Studio.

VERY annoying and it's happening atleast 50% of the time I try and changes styles. Currently the form doesn't even use any styles beyond the default look and feel - this is the first style I'm trying to create in this app.

The 'No such property registered: HotTracking' varies by the way - I've had 'isClicked' and others instead of HotTracking.
I'm running Q3 2008, but prior to this had Q1 2007 installed.

Thanks,
Richard.

[Solved] RibbonBar with RadTextBoxElement - multiline problem

Hi everyone!

I need to add a multiline TextBox to the RibbonBar. I used that code in the desingercode (short version ;) )

    
            private InitializeComponent() 
        
            { 
        
            //(...) 
        
            this.radTextBoxElement = new RadTextBoxElement(); 
        
            //(...) 
        
            // radRibbonBarGroupMessageText 
        
            //  
        
            this.radRibbonBarGroupMessageText.Items.AddRange(new Telerik.WinControls.RadItem[] {this.radTextBoxElement}); 
        
            this.radRibbonBarGroupMessageText.Name = "radRibbonBarGroupMessageText"; 
        
            this.radRibbonBarGroupMessageText.Orientation = System.Windows.Forms.Orientation.Horizontal; 
        
            this.radRibbonBarGroupMessageText.Text = "Treść"; 
        
            // 
        
            //(...) 
        
            // 
        
            } 
        
            RadTextBoxElement radTextBoxElement;

then, using the designer I heve set the properties of this TextBoxElement.TextBoxItem : multiline to true, and the null text to proper info and AcceptReturn = true;

When I run my application, I see the null text, but I can start a new line with enter key and even when I put a lot of text (reach right edge) text doesn,t break to new line... Can someone help me fix that? I will be greatfull.

Texbox with different disabled style

Hi,

while some of your controls have a "UseDefaultDisabledPaint" property I can't find this on RadTextBox.

My need:
I hav a data entry application.
Left I have a list of items - and on the right the details of it.
The user can edit the details by pressing a button which enables the controls (textboxes and so on).

For better visibility it would be great to have a special style on disalbed Textboxes.

By the way - the only reason to use RadTextBox instead of Forms.Textbox is the idea to use styles for better visiblity.
Because I see no other reason -- it's more oposite! With Forms.Textbox SHIFT-TAB works!!

So is there a way to change the disabled style?
Even having BLACK as ForeColor would be enough!

Regards

Manfred

Refresh radGridView

Hi All,

I have a radGridView that is populated via a TableAdapter:

    
            buUserTableAdapter buUserTA = new buUserTableAdapter();  
        
            protected BindingSource buUserBindingSource = new BindingSource();  
        
            buUserBindingSource.DataSource = buUserTA.GetData();  
        
            this.radGvAdminUsers.DataSource = buUserBindingSource;

The radGridView is read only, however, I have a "detail" section below the radGridView where users can edit the contents of the records. The database is updated upon clicking a "save" button via a stored procedure of the TableAdapter:

    
            private void radBtnAdminSaveUser_Click(object sender, EventArgs e)  
        
            {  
        
                int userId = Convert.ToInt32(lblAdminUserDBID.Text);  
        
                string userLogin = this.radTxtAdminLoginId.Text.ToUpper();  
        
                string lastName = this.radTxtAdminLastName.Text;  
        
                string firstName = this.radTxtAdminFirstName.Text;  
        
                string userPhone = this.radMTxtAdminPhone.Value.ToString().Trim();  
        
                int userRole = Convert.ToInt32(this.radComboAdminRole.SelectedValue);  
        
                string userRoleDesc = radComboAdminRole.Text;  
        
                bool userActive = Convert.ToBoolean(this.radCbAdminUserIsActive.Checked);  
        
                if (userId != 0)  
        
                {  
        
                    buUserTA.UpdateSP(userId, userLogin, lastName, firstName, userPhone, userRole, userActive, System.Configuration.ConfigurationManager.AppSettings["UserNetworkId"].ToString());  
        
                }  
        
                else 
        
                {  
        
                    //Need to do an insert for a new user and update for the new id  
        
                    userId = Convert.ToInt32(buUserTA.InsertSP(userLogin, lastName, firstName, userPhone, userRole, System.Configuration.ConfigurationManager.AppSettings["UserNetworkId"].ToString()));  
        
                }  
        
            }

When this is clicked, the database is properly updated, however, the radGridView does not refresh to reflect the changes.

From what I've read, it seems like the radGridView is supposed to automatically updated. What am I missing or doing wrong? Any help with this is greatly appreciated.

Do not allow user to select item

Hello,

I would like to not allow the user to select an item in my radListBox. I have set the selection mode to none, but this still places a border around the edge of the item. How can I ensure that items do not show as selected in any visible way?

Thanks

Richard
