Caching User Control And Clearing That Cache Programmatically?
Jul 13, 2010I'm trying to cache user controls and on some pages i want to cache single objects. There are multiple ways of implementing caching, and my head is breaking over it.
The way I see the caching options now:
You have the PartialCaching option which is set to cache the control for 30 minutes, and after that it clears itself... You have the varyByParam to identity the page by its querystring paramaters... or other vary options
But i just cant find an appropriate way to add caching to a control, and be able to clear the caching programmatically when i update one of the objects used in the control from the backend.
You can do HttpContext.Current.Cache.Insert(), which accepts a key on which you can destroy the caching item later by using remove... This can save objects in cache but can you use options like varyByParam?
My questions are burnt down to two:
Is there a way to clear the caching on specific user controls from the code? If yes, can this be done according to the varyby options? How would the object caching respond to logged in users or anonymous users using Insert()?
EDIT: I'm caching multiple things.... And I'm really flabbergasted in which choice to make referring to caching. Can the Cache.Insert be varied by Parameters?
The main problem is peopling editing things from the backend, which needs to trigger an event that reinstantiates or clears all caching items referring that object.
AJAX :: Control Toolkit Clearing Request.QueryString?
Dec 16, 2010I have a web form, and it appears that when I add the AJAX control toolkit on my webform, my Request.QueryString is clearing out. Here is what happens:
1) User clicks next on form 3, and I load up form 4 (form 3 passes query string to form 4)
2) User clicks next on form 4, and form 4 checks the query string that was passed by 3, and it's emtpy
This only happened when I added AJAX functionality.

Web Forms :: Set The Current Value Of A FileUpload Control?
May 21, 2010I have a 2 FileUpload controls.
Once the user selects a file in the first control, I want to set the default value for the 2nd control to be the value from the first control.
For example, if it were textbox controls I would just use TextBox1.text = TextBox2.text.
How do I do this for FileUpload controls? I tried a few different properties, such as FileUpload1.FileName = FileUpload2.FileName but I get an error saying that they are Read Only.
Web Forms :: Hide FileUpload Control?
May 7, 2010I would like to simply have an image button on my page that would show an image that says something like "Upload File".When the user clicks the button I would like for it to automate popping up the "select file dialog" exactly like the "browse" button does on the FileUpload control now. Then if the user selects a file and click "OK" I want to do a post back where I can then initiate the upload. If the user clicks cancel from the dialog I would do nothing.So all I am trying to do her is make it so that the user does not see the text box for the file name and replace the plain old browse button with an image and do a postback if they click ok from the dialog.

Sep 28, 2010I have a site that uploads multiple PDF files from a CD from one specific computer and that computer is the server that will store the PDF files. I want to do this without having doezens of fileupload controls as the number of PDF files vary from CD to CD.
My problem is that I want the whole process automated. The site will read the names of the PDF files on the CD to the SQL server, which will match, parse, and delete unneeded information with the actual names in a comma delimited textfile. I have that all completed, but i'm only getting the filenames of the PDF and no the contents of the PDF's themselves (They all show 0KB). I am certain that the problem is that i'm pulling from Directory.GetFiles and it's only saving the filenames instead of the files themselves. Is there any way to set the upload path for the filecontrol?

Web Forms :: FileUpload Control Loses Value On Postback?
Sep 11, 2010I'm having a little problem with my file uploading. Does anybody know how to maintain the value in the FileUpload control between server posts?
I have a form which, among other things, uploads a file. I am using an ileUpload control (created dynamically) to let a user browse their PC for a file and then using the SaveAs method to upload the file to the server.When I'm selecting a file and Click on Next button for processing then selected file is lost.
Same is happening with me with HtmlTextArea (dynamically generated) , the problem was that I was not again re-initializing the controls after postback. What I did is re-initialized it in Init method of placeholder (as I have created/placed all dynamic controls in placeholder ).
But this thing is not working for fileupload control. I found solution in one of the forum is that "use hiddenField Control to transfer the selected file from the client to server"but this mechanism will only help to retain the name of file
in a hidden variable and the FileUpload1.PostedFile.SaveAs(filename) will not work bcz of absense of object (fileupload1).
here is code:

I have done almost the same in different test project , it works . I dont know whats wrong?

Web Forms :: How To Get The File Path Using The FileUpload Control
Sep 15, 2010The requirement is that the whole original file path be saved to the database; for example: L:folder1folder2xyz.doc. However; the FileName property of the FileUpload control will only give "xyz.doc". We are interested in obtaining the full path only and really not interested in using the control to do any upload.
Is there any way to get the full path? We would like our user to be able to browse to the target file instead typing into a textbox because the folder name could be very long and several levels deep in our organization.
