RadRibbonGroup.LargeImage

[TRW]

Hi!

I need use a different image from data base, i will asign the image(PNG) in order of an specific process.

The images recovered from data base are created in a temporal folder in order to use them in the dynamic process when i need chage the image.

At this moment the asignation of an image is ok but i can not see the image in the button:

RadRibbonButton objArea = new RadRibbonButton();
objArea.LargeImage = new BitmapImage(new Uri(auxPath + (string)dt.Rows[i].ItemArray[1], UriKind.Relative));
objArea.Size = Telerik.Windows.Controls.RibbonView.ButtonSize.Large;

If i use a RadRibbonButton created manually in xaml, i can change the image and the result is ok.

//control created in xaml
btnExample.LargeImage = new BitmapImage(new Uri(auxPath + (string)dt.Rows[i].ItemArray[1]));

If you help me i will be greateful.

Hello,

I wasn't able to reproduce the described behavior. Can you please take a look at the attached project and let me know if I am missing something? Also, please make sure that the BitmapImage object gets a valid Uri that points to the specific image file.

Thanks Dinko!

I solved this item using a RadRibbonButton created manually with LargeImage alrady seted and copy some properties to the new dynamic buttons, that was the only way to add the image to the RadRibbonButton. I checked your example, i have a detail, I am using image from data base for that reason I don't have the images in the project.

This is the code I used to create the image:

01.private static BitmapImage GetImage(byte[] data, string imgName)
02.{
03.    MemoryStream ms = new MemoryStream(data);
04.    System.Drawing.Image img = System.Drawing.Image.FromStream(ms, true);
05.    ms.Close();
06.
07.    string auxPath = AppDomain.CurrentDomain.BaseDirectory + @"\temp\";
08.    if (!System.IO.Directory.Exists(auxPath))
09.        System.IO.Directory.CreateDirectory(auxPath);
10.
11.    img.Save(auxPath + imgName, ImageFormat.Png);
12.
13.    return new BitmapImage(new Uri(auxPath + imgName));
14.}

 

And the code for assign to the new RadRibbonButton the image

01.objArea.LargeImage = btnExc.LargeImage;
02.NLI_DataObject objImg = NLI_ViewModel.GetData(objZone.IdImage);
03.objArea.LargeImage = objImg.NewImage;
04.
05.public static NLI_DataObject GetData(int idImage)
06.{
07.    DataTable dt = SQLComm.App.FATT.NewLargeImage.GetImageFromDB(idImage);
08.
09.    NLI_DataObject obj = new NLI_DataObject();
10.    obj.NewImage = GetImage((byte[])dt.Rows[0].ItemArray[0], (string)dt.Rows[0].ItemArray[1]);
11.
12.    string[] extAux = dt.Rows[0].ItemArray[1].ToString().Split('.');
13.    obj.OnlyName = extAux[0];
14.    obj.OnlyExt = extAux[1];
15.    obj.ImageName = (string)dt.Rows[0].ItemArray[1];
16.
17.    return obj;
18.}
