Did you do anything like a simple google search before asking? You should have got thousands to results if you had....

See here: Why do I get a "Parameter is not valid." exception when I read an image from my database?[^] - it explains teh way to get the image, and explains how to store it, just in case you might have got that wrong! ;laugh:

Hello ,
You can convert the image from bytearray to its original form by this function

public Image GetDataToImage(byte[] pData)
       {
           try
           {
               ImageConverter imgConverter = new ImageConverter();
               return imgConverter.ConvertFrom(pData) as Image;
           }
           catch (Exception ex)
           {
               return null;
           }
       }

Now pass the byte[] array in the function , which is stored in Database and you will get Image .

Thanks

Member 11148509 9-Jul-15 4:42am

i could store value from databse in a variable ..now i need to convert that hex value to image....how can this be done????

Animesh Datta 9-Jul-15 4:54am

to set the value of RadBinaryImage used DataValue property .
RadBinaryImageobject.DataValue = (byte[])(imagedata);

Member 11148509 9-Jul-15 4:57am

imagedata????

Animesh Datta 9-Jul-15 5:00am

here imagedata means byte array data from database.
