I'm looking for ways to reduce the size of my page . I have a page that just renders a gridview - no images - and it is over 400k!
Looking at the html that is generated I see the names of the controls in the gridview are very very long. For example: ctl00_ContentPlaceHolder1_releaseGV_ctl149_lblBuy
My gridview is about 200 rows by 13 columns = ~ 2600 spans with very long names rendered. The above example is 49 characters X 2600 controls = 127,400 characters just in control ID's!
The actual data on my page ins't anywhere near a tenth of that!
I am already storing viewstate on the server.
YES, I will put a pager on this page to bring down the number of rows. Also, I've seen sever other posts related to page size with some excellent content. I will follow up on them - however I have not seen this specific question answered.
Here is a sample of my page. As you can see there is not much data and a lot of html!
I am uploading images in c# windows application. I am uploading the images folder wise. In one folder there are 200 to 3000 images. My one images size is about 3.10 MB to 6.2 MB. Its dimensions are 3008 x 1960, 1960 , 4000 x 2600. 6000 x 4000 . while uploading i am reducing the size of image to 400 x 266 or 266 x 400 depending on the height and width of image. but still my image size is about 227 KB. Now i want to reduce the image resolution to decrease the image size.
i want to reduse the size of barcode image in this code . i tried to reduce but its cutting the number ... how can i reduce the size of this barcode image

I have stored images in folder each images is more than 700kb so datalist binding process became slow.so it is possible that while loading record and corresponding images from folders Can I reduce the image size or compress images so that record fetching become faster.In database i m stroing image path and image is stored in directory.
In my web application, I have used AJAX Toolkit and my .net version is 3.5. When I run the application and save the page, so many ScriptResource.axd and WebResource.axd generate which makes the file size 200 to 300 KB more big. After doing the same procedures mentioned in the above link, it was working fine as all ScriptResource.axd and WebResource.axd file is removed.
But when I go from one page to another page using on click, then Object Expected Error comes and when I debug it,I found one ScriptResource.axd file containing query string like .axd?d=-bA.like this and Request. GetResponse cannot find the file and it gives 404 errror (File Not Found).
I have uploaded a .jpg image and resized as Small and Large thumbnail. The small image is (135 X 173) but after resizing the small thumbnail image file size is of 40.8 KB. And mostly all images (around 64) thumbnails having file size more than 40 KB. Due to which thumbnails taking lot of time to get display.
Is there a way through which we can reduce the image file size upto 8 to 12 kb, but without effecting image quaity??
Below is the source code that i am using for resizing an image:
If FileUpload1.HasFile Then Dim stream As Stream = FileUpload1.PostedFile.InputStream Dim x As String = IO.Path.GetExtension(FileUpload1.FileName).ToLower If x = ".jpg" Or x = ".jpeg" Then Dim image As New Bitmap(stream)
This is the IF -Else ladder which I have created to focus first visible control on my form.According to the requirement any control can be hidden on the form.So i had to find first visible control and focus it.
if (ddlTranscriptionMethod.Visible) { ddlTranscriptionMethod.Focus();
