When is VisualElement set for GridViewRowInfo

I'm currently using the grid.Rows.Add() method to add a new row when a particular event fires inside my application.

This works fine.

However, I am now trying to set the ForeColor of the row after I add it, but the VisualElement property is null, in the following code sample:

    
            int rowIdx = traysGrid.Rows.Add( 
        
                                    tray.TrayID, tray.Barcode, 
        
                                    dataContext.Locations.Where(loc => loc.LocationID == trayHistory.LocationID).First().Name 
        
                                    , 
        
                                    trayHistory.ArrivalDate, 
        
                                    AuthenticationController.GetLoggedInUserName(), 
        
                                    tray.Notes 
        
                                    ); 
        
            GridViewDataRowInfo row = traysGrid.Rows[rowIdx]; 
        
            traysGrid.GridElement.BeginUpdate(); 
        
            row.VisualElement.BackColor = Color.Green; 
        
            traysGrid.GridElement.EndUpdate();

I have used this method successfully when inside a foreach loop, but using it doesn't seem to work as above.

Any advice or ideas?

Thanks

RadAutoCompleteTextBox - Multi Column

Hello,

Is it possible to have the AutoCompleteText box display mult-columns, eg
USD | US Dollars
GBP | British Pounds
EUR | Euro's

Also is it possible to have the auto complete work on both columns so I can start to type GBP or Briti... and it will work as per single items?

Thanks

Terry

CarouselContentItem contentItem = (CarouselContentItem)button.Parent;

zoomedItem = contentItem;

button.ButtonFillElement.Visibility = ElementVisibility.Collapsed;

currScaleFactor = Math.Min(

((float)size.Width) / button.Size.Width / 2f,

((float)size.Height) / button.Size.Height / 2f);

5,

20

);

scaleChange.AnimationFinished += new AnimationFinishedEventHandler(scaleChange_AnimationFinished);

SizeF offset = new SizeF(

(size.Width - contentItem.Size.Width * currScaleFactor) / 2f - contentItem.Location.X,

(size.Height - contentItem.Size.Height * 0.50f * currScaleFactor) / 2f - contentItem.Location.Y);

RadDropDown Text Validation

Hi,

I have a RadDropdownlist which should allow the user to type in only numeric values in it. Validations in Key_Down and Key_Press event does fire but it is not working. I have similar validations for normal textboxes and it is working.

Is there are any ways to restrict the user to type only numeric values in RadDropDown?

private bool nonNumberEntered = false;

protected void radDDLAccountNo_KeyDown(Object sender, KeyEventArgs e)

{

ValidateNumericField(e);

}

private void radDDLAccountNo_KeyPress(Object sender, KeyPressEventArgs e)

{

KeyPressEvent(e);

}

private void ValidateNumericField(KeyEventArgs e)

{

nonNumberEntered = false;

if (e.KeyCode < Keys.D0 || e.KeyCode > Keys.D9)

{

if (e.KeyCode < Keys.NumPad0 || e.KeyCode > Keys.NumPad9)

{

if (e.KeyCode != Keys.Back)

nonNumberEntered = true;

}

if (Control.ModifierKeys == Keys.Shift)

nonNumberEntered = true;

}

private void KeyPressEvent(KeyPressEventArgs e)

{

if (nonNumberEntered == true)

{

e.Handled = true;

}

Thank you in advance for the help.
