[Solved] DataBinding and custom controls

Hello -

If I set the FieldName of a databound column, the corresponding values are displayed within the column. This is normally desirable. However, I happen to be using a custom element in that column, and the text drawn by the grid interferes with my element's visualization. If I do not set the FieldName of the column, the problem disappears. However, I then cannot sort or group the column. Is there a way for me to sort/group by a databound column without the grid displaying the value of the column in the cells?

Thanks,

- Mike

Chunk Border Color

Hello, Ive been testing some of your controls and I love them, they are awesome. But Iam having a problem with the RadRibbonBar control. I cant find how to change a chunks border color. It seems like this should be really easy but I cant find how to do it anywhere. Ive tried using the theme builder but it seems like the designer stops just short of having the chunks in it. The theme builder stops at ExpandableStackLayout with nothing below it in the tree and if I use Edit UI Elements thats where all of the chunks properties are located. Now if try to use Edit UI Elements to try to change the chunks properties it only changes the "add new group" border color in Visual Studio's designer not any of the existing chunks border colors. I have also tried changing the color through code but I cant find a border color property anywhere. I know this has to be possible because the different themes the control comes with have different color borders on their chunks. Can you please point me in the right direction with a bit of sample code. I'm probably going to feel really stupid when you show me.... probably right in front of my face. Thanks for the help and for a great product.

[Solved] BestFitColumns not working

I'm finding that if I call BestFitColumns, the column widths are set to one pixel. I'm guessing this is happening because I call it too early, before the columns have been filled with data. Can you suggest a good time to call this method? Also, is it possible to combine the best fit behavior and still make one of the columns be "stretchy" -- i.e. take up the remaining space? My goal is that all but one of the columns would size to their content, and that the remaining column would stretch to consume the remaining space.

Default Context Menu question

I'm wondering how I could catch the event when you click on the "delete row" in the default context menu.

What I want to do is when I click on that, it removes the row from one gridview and it has to be added to another gridview.

I was searching in the helpfiles but I didn't find anything that could help me.

thanks in advanced

Children element label NullReferenceException

An error occurs in the cellFormating event:

in the first databinding of gridview the error does not happen , but if I try a second databinding, for refresh the gridview,
the following error occurs:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object.
at Telerik.WinControls.Primitives.TextPrimitive.MeasureOverride(SizeF availableSize)

The code where the error occurs is the folowing:

    
             private void gvPremios_CellFormatting(object sender, CellFormattingEventArgs e)  
        
                                     {  
        
             if (e.CellElement.ColumnInfo is GridViewDataColumn && !(e.CellElement.RowElement is GridTableHeaderRowElement))  
        
                                         {  
        
                                                 GridViewDataColumn column = (GridViewDataColumn)e.CellElement.ColumnInfo;  
        
                                                 if (column.DataField == "MyColumn")  
        
                                                 {                         
        
                                                     if (e.CellElement.Children.Count > 0)  
        
                                                         return;  
        
                                                     RadLabelElement element = new RadLabelElement();  
        
                                                     element.Text = "<html>This is a test..."                                           
        
                                                    e.CellElement.Children.Add(element);  
        
                                                 }  
        
            }

The strange thing is in the "element.text" property, that if I not put the the tag "<html>"... the error does not happen, but, i need formating the field with a html code...
And the property "DisableHTMLRendering=false" is not working as it should, leaving the whole column unconfigured.
