AutoSizeRowsMode

Hi,
Qs1: How can I set auto size rows mode for the radGridView?

For the windows datagridview, When the cell data is wider than the column, having the auto size rows mode set to Displayed cells will resize the row to show all cell data. How can I have the same in a radgridview?

Qs2: Is there a way to set tool tip text for those cells that have data hidden due to less column width?

Hope you will have solutions for these..

Bottom Row Overwrites Grid Border

Hello,

I've discovered an issue in my gridviews where the last row paints over the grid's bottom border when the grid is full of information. Is there a way that I can make the grid border draw on top of the rows? If you guys have trouble reproducing this, let me know and I'll send a theme where this occurs. It actually occurs in all of my themes, so I imagine you guys wont have much trouble. I use a row-height of 18 if that helps.

Thanks!

Jeremy

Dynamically Resize GridHeaderRowElement?

In order to try to bend the will of the GridView to do something we're attempting, I'm trying to dynamically either completely hide or to change the height of a SPECIFIC group header row down to something 1 pixel in height if the group text is blank.

I've tried all of the following:

    
                        if (e.RowElement is GridGroupHeaderRowElement) 
        
                        { 
        
                            e.RowElement.Size = new Size(1, 1); 
        
                            e.RowElement.ShouldPaint = false; 
        
                            e.RowElement.Visibility = ElementVisibility.Hidden; 
        
                            e.RowElement.MinSize = new Size(e.RowElement.Size.Width, 0); 
        
                            e.RowElement.Size = new Size(e.RowElement.Size.Width, 1); 
        
                            e.RowElement.CoercedSize = new Size(e.RowElement.Size.Width, 1); 
        
                            e.RowElement.StretchVertically = false; 
        
                            this.ApplyThemeToElement(e.RowElement, "ControlDefault"); 
        
                        }

All this has done has completely hidden the group rows but still leaves blank space where they shuold be, however now I can't select them (which is nice).

Is there any way to change the size so the space left when hidden is minimized?

Thanks in advance.

[Solved] Row conditional formatting with enum value

Hello,

I am having problem setting up conditional formatting with enum value.

The grid is bound to the list of objects which have the enum called Priority { High, Normal, Low }. I am setting different colors based on the priority and the formatting is not working. The case sensitive has no effect.

Any ideas ?

Change Skin at Run Time

I get one thing sorted then hit another problem, I'm sure someone will now this.

I want to allow the user to choose the SKIN from a combo box and refresh the chart to display the new colour scheme.

I thought it would be an easy bit of code like:

RadChart1.Chart.Skin = "Black"

RadChart1.UpdateGraphics()

Thanks in advance Guru's,

Gary

[Solved] EditorRequiredEventArgs.Editor always null

Hi,

I have a grid (2009 Q2) with a number of GridViewComboBoxColumn attached to them, each of which is populated from an array data source. I wish to highlight one of the items in the combo when it is dropped down for some reason (i.e. changing the font to Bold). To do this I intercept the EditorRequired event to get access to the default editing control being supplied for the cell - my idea is that I can access the created control and manipulate its contents. Here is my method

static

void grid_EditorRequired(object sender, Telerik.WinControls.UI.EditorRequiredEventArgs e)

{

Telerik.WinControls.UI.

RadComboBoxEditor comboEditor = e.Editor as Telerik.WinControls.UI.RadComboBoxEditor;

if (comboEditor != null)

{

Telerik.WinControls.UI.

RadComboBox comboBoxControl = comboEditor.EditorElement.ElementTree.Control as Telerik.WinControls.UI.RadComboBox;

// Do some work with the combo box control here

}

}

However the e.Editor is always Null (the e.EditorType is typeof(RadComboBoxEditor) as expected).

I see from several postings that I would expect to have an instance of the RadComboBoxEditor in the e.Editor property, and that this event is the correct one to do what I'm trying to do.

In addition, other posts have been shown solutions which show that RadComboBoxEditor class has an Items collection, but in my edition of Rad this property does not exist, and I'm guessing my route through to the combo box items collection is through .EditorElement.ElementTree.Control.

Can you help untangle this for me ?
