Hi there,

I've a Bitmap image which is drawn from the Back end values.
I've created a User control to get the bitmap image.But when I place the user control inside my Aspx page, all other controls get vanished.Only the Bitmap image get displayed.How can I manage this issue??? I want to pass the flags for drawing image to back end via Aspx page, So the controls should be there (Visible)....

Thanks in advance....

Solution 1

Put PlaceHolder control on your page, and put the image in that. Unless you need some sort of special profcessing, a UserControl isn't appropriate.

No my output is directly to the bitmap in the User control not to an asp image....

How you are showing the image on the Usercontrol......i mean using any image server control or any other method....

No I'm not using image server control... I just fetch it in a Bitmap object and displaying it....

Once, I wrote code to draw a captcha image, and this is how I got it on the page:

C#

int imgHeight = 60;
int imgWidth = 160;
Bitmap objBMP = new System.Drawing.Bitmap(imgWidth, imgHeight);
Graphics objGraphics = System.Drawing.Graphics.FromImage(objBMP);

// Set the content type and return the image
Response.ContentType = "image/GIF";
objBMP.Save(Response.OutputStream, ImageFormat.Gif);
objFont.Dispose();
objGraphics.Dispose();
objBMP.Dispose();

Thanks for ur reply..
Yes that I agree... For me too the image is displayed in the web page... But the issue is when the bitmap is Displayed on the web page all other controls get vanished. How I can set to display the image in a specified portion only,not in the whole page..

You have to find a way to inject it nto the response. The only way I know to do that is to put a html element (maybe a div), and then and image in the div with no source set. Finally, save the bitmap to a file and set the source of the image element to the file's url.
