I have stored my image in database as format, how do i retrieve the image to imagefield without using gridview or datalist? I just want to retrieve it to the imagefield only
You can use the httphandler to retrieve the binary image, and then bind it to one image contorl with src property. Check this link.

I Create an SendWorkOrder.rdl Report for SSRS. In the dataSet I have a field with Image dataType(Value in that database column eg- 0x89504E470D0A1A0A000000....).
Followed msdn article to create data bound image.
I Tried following expressions, But Image Not Showing
=First(Fields!Signature.Value, "CasingList")
=System.Convert.FromBase64String(Mid(System.Convert.ToBase64String(Fields!Signature.Value),105))
=Convert.FromBase64String(First(Fields!Signature.Value, "CasingList"))
You are trying to create an image in your report from the database?
I assume you have set up an image control as follows
Then set the field to be a reference to your 0x89504E470D0A1A0A000000... data
=Fields!Marker.Value
And the Mime type to the the corresponding image format
=Fields!Marker_Type.Value
(note this should be something like image/jpeg or image/png)
Without the image format nothing will render.
A set up such as the above should render correctly, as shown

I need a help to fill FileUpload Default file path using C# code
here is a file path Server.MapPath("~/DemoTrack/DemoWorkout.mp4");
which i want to fill in FileUpload by code of C# if the FileUpload value is null. in asp.net
please let me know how can I fill the FileUpload by code
I'm doing this
FileUploadDemoVideo.SaveAs(Server.MapPath("~/DemoTrack/DemoWorkout.mp4"));
FileUploadAudio.SaveAs(Server.MapPath("~/DemoTrack/DemoTrack.mp3"));
String DfileExtension =
System.IO.Path.GetExtension(FileUploadDemoVideo.FileName).ToLower();
String AudioExtension = System.IO.Path.GetExtension(FileUploadAudio.FileName).ToLower();
i want to FileUploadDemoVideo and FileUploadAudio by code this is a file path Server.MapPath("~/DemoTrack/DemoWorkout.mp4") which i want to fill in FileUpload with a code wright in c# i just want to fill a FileUpload control then i can get a fileName and Extension so can convert in a Default value in byte[] and store that byte in sql data base if use didnt select the any file using FileUpload the Default value audio and video byte will be saved in database. as per that file which i fixed for audio and video.
I want to add a fix audio and video fill url in both audio and video FileUpload control with the code.
According to my understanding, you want to save the default audio & video, if there is no input from the user. If this is the case, you can directly save the file onto database without involving your file-upload control. Filling the default file path on the file-upload control doesn't make any sense on client machine, since your default contents resides on server.

To export a gridview to a image,
1.First export gridview data to pdf.
2.Then convert it into image.
I don't want save image in database. My application going to work on different shops i want show their logos on report.rdlc. For that i want to know, can i show image on report.rdlc by using path of image only? I tried to create parameter for Report.rdlc in ReportData but there is not any image Datatype.
Yes, you can:
Set image Source to External
Set image Value to an URL or file path
Set EnableExternalImages=true in your report code
You can also refer to http://msdn.microsoft.com/en-us/library/ms251715(v=vs.80).aspx for some additional info, but those steps above must be enough.
If any user gives the information of his photo in binary objects how can i search it and how can i display the corresponding image that was stored in the sql database
I will suggest to create a CRC/Hash of the Image File and then just search for this number. If you found it then compare the full Binary Format to be 100% that is the same.
To display the image I suggest to create an .ashx handler, that you send the ID of the image encrypted, then inside the handler you read the Image from the database and send to an img anchor.
eg.
<img src="MyImageHandler.ashx?Id=7738akj12391723">
I found some existing examples for display the image from the Database
