[Solved] Conditional formating... if less than ...

Hello Dear Experts. :)
I would like to set the conditional formatting from the code for one column.
The row should change color when the value in column (type datetime) subtracted from the results of today's date is less than 1 month.
Is there any possibility to do this? Or do I have to subtract the date using sql, and select as an additional value?

Best Regards
Krzysztof

GridView DataBinding: Faster with LINQ or Dataset?

I have a project that needs expedited and I'm new to Telerik components so I need some advice please.

I was hoping to use LINQ to populate my grid and I'm using a binding source as an intermediary. The grid was not saving my data and it is not clear by the documentation on how to do this. However, it appears, via forum suggestions, that I'll need to create some type of saving mechanism in the RowValidated event to accomplish this if I use LINQ.

So, would it be faster for me to use a dataset and tie the grid into that instead? Are there any considerations when doing it this way? I'm hoping that I can create the dataset, tie the grid to it and I'll be done.

Thank You.

Win Integration for WinForms

I can add the components for all the WinForm controls to our OpenSpan visual designer and they work awesomely. Great solid work Telerik. This allows my customers to drag n drop all the Telerik windows controls into the OpenSpan Studio so they can drive automations and integrations to any enterprise legacy application (win32, web, java, lotus, mainframe etc.,) running on the desktop.

However, in the demo, I can see the Win Integration components but they don't appear to be in the win.controls dll like all the other visual components.

Is there a plan to have them as components. OpenSpan Studio is a visual designer and automation IDE and I didn't want our customers having to drop to code per se' if they don't have to.

Thanks.

SCSF view is taking time to load(Optimise loading of views in SCSF)

Hi,

I have developed a smart client desktop application using SCSF.

It has an MDI and MDI child forms opens over it(It is similar to windows menu based application using MDI) .

The problem is that the MDI child forms (i.e. the views) take a few seconds to open and load.

Is there any way of minimising the time it takes.

The forms are having simple telerik text boxes and telerik labels and telerik grids(which has two columns and is not populated during load)

I call a webservice at form load and have tried to comment the service call; Even then it takes the same time so I have ruled out the possibility of service delay.

Nothing else is done at the form load except the form is rendered

Is it because I am using telerik that the form is taking time to render the telerik controls or because of SCSF CAB.

But a simple windows forms in the same project gets loaded faster than the telerik one.

May be SCSF might be tuned up to load the views faster or there is some way to make the CAB work faster which I am unaware of.

Thanks in advance.

Global Themes

I am new to the Telerik WinForms controls (so be gentle if this is dumb question).

I have looked through the doc, watched videos and searched the forums, but I can not figure out how to set a theme that applies to an entire application or even all controls on a form. It seems like you have to set the theme on every control on every form. What am I missing?

RadRadioButton and TextWrap property

Does RadRadioButton support text wrapping?

See this picture : if I set or no TextWrap property - text is always in one line.

By the way, if I set proprety AutoSize to True, then False again - text is wrapped, but in designer, not during execution. And after closing/starting Visual Stiudio - text is again in one line.

PS: Same question about RadCheckBox control.

RadComboBox FormatString Not Working?

I'm trying to create a control with formatted entry and a drop-down suggestions list, specifically an am / pm time field with seconds with a list of suggested but not mandatory times. I'm trying to use a RadComboBox and setting its FormatString Property to do this. I couldn't find any docs on this Property so I tried using the Mask characters from the RadMaskedEditBox docs. I've tried "HH:mm:ss tt" and simply "##:##:## LL". In neither case did it restrict values to the specified format or move the cursor to next wildcard section when I tried to type or right-arrow past non-wildcard characters of the mask or press space in front of non-wildcard characters like RadMaskedEditBox does. I've tried setting FormattingEnabled to True and False. Any ideas? Thanks.

BTW, what are the DisplayMember and ValueMember Properties for?

How do I access a grid on a DocumentWindow?

My main form loads a RadDock and a toolWindow containing a PanelBar and RadList.

On clicking items in the RadList a new DocumentWindow is opened. This window is a class which inherits from DocumentWindow.

This loads the document window

    
            LogDocument documentLog = new LogDocument(); 
        
            documentLog.Text = documentTitle; 
        
            documentLog.CurrentFileId = selectedIndex; 
        
            documentLog.Load();  // Loads data into grid 
        
            AirFile.AddNewMostRecentFile(documentTitle, selectedIndex); 
        
            this.radDock.AddDocument(documentLog);

My inherited class (only some of it for brevity)

    
                class LogDocument : DocumentWindow 
        
                { 
        
                    public LogDocument() 
        
                    { 
        
                         AddGridToForm(); 
        
                    } 
        
                    public void Load() 
        
                    { 
        
                         LoadGridWithData();

                        Save(); 
        
                    }

In the constructor I add controls to the document including a RadGrid. When many documents are opened I have a UI similar to VisualStudio.

My Main form has a menu containing a delete button. When this button is clicked I want to delete the current grid row on the current active window.

My difficulty is that I cannot figure out how to reference the "delete item" code in the class LogWindow:

    
                    public void DeleteRow() 
        
                    { 
        
                        // Delete code here 
        
                        // then save changes to db 
        
                        Save(); 
        
                    }

Any help would be appreciated.
