I have seen many posts here regarding this, but none with a successful solution.I m using a asp.net fileupload control & not the html one.I have various controls on the page, & on a listbox control, listitem selection, page postbacks.So before it, if i had selected a file for upload & page poastbacks, the the file goes off.Now on postback, I have got the filename in a hidden field, but since the Fileupload control doesnt have any setter methods, not able to get how to set the hidden field value & how to set it...
I have a FileUpload control in an UpdatePanel and when user select a file, the full file path will will be stored in a hiddenfield, and during postback, i would like to assign the full file path in the hiddenfield back to the FileUpload control textbox, possible to achieve that?
I'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?
I'm using five FileUpload controls on a single web form. Besides allowing the user to upload a file I also am collecting user data. Problem I run into is during the server side validation if any of the user data is invalid on a post back when content it redisplayed the FileUpload controls loose the client url that was selected when browsing. How can I keep that path or set the pathing on the control so they do not have to keep rebrowsing for the files on data validation errors? Right now breaking up the two form sets user data and file upload into two pages is being frowned upon and requirments would like it to be on all one page.
I have a FileUpload control and a DropDownlist control in an UpdatePanel and when user select a file for the FileUpload control (no upload yet), in the meanwhile the user select an option from the DropDownList control which will cause a postback! Once the page postback, the path selected in the FileUpload control will gone. How can i remain the path in the FileUpload control? File uploading function was working. I hope can remain the path in the FileUpload control during postback.
I have tried the solution below but the "FileUpload1.HasFile" will return false to me.
If Session("FileUpload1") Is Nothing AndAlso Upload.HasFile Then Session("FileUpload1") = Upload lblPhotoUploadErr.Text = Upload.FileName ElseIf Session("FileUpload1") IsNot Nothing AndAlso (Not Upload.HasFile) Then
I am using .net 3.5 framework. I have a Tabcontainer inside that I have place asp.net fileupload control which is inside update panel. It's been known fact that fileupload control does not work under update panel unless we use Postback Triggers.
i hv postback event executing after i am trying to upload a file to server to ask for conformation by the user. after postback fileupload control gets cleared and i am not able to get its value after postback. controls viewstateEnabled property is true. How do i assign a file path to fileupload control after postback.
My <input id="FileUpload1" name="FileUpload1" type="file"> and country dropdown both are inside update panel , now on selectedindexchanged it do postback , which i am triggering in update panel to avoid page refresh .
Now the problem is when i select any image in fileupload and then select country , my selectedimage vanishes but its path stays in textbox .
This upload is working. But why the page is getting refreshed? this is not partial post back and instead it 's full post back. i have read the articles for the fileuplaod with issue inside the update panel. is there any way to achieve this asynchronous upload on button click?
I don't want to use the Ajaxtoolkit Asyncupload because that will upload (Ref : [URL] ....] the moment when we seelct the file itself which i don't want to do that. i need to do on the button click event.
i have searched on google and got an article [URL] keep selected file in fileupload control even after page postback. But it's not working at all. So is there any way through which we can keep selected files in fileupload even after page postback.?
I have an IEnumerable< T> which is declared on the page like this:IEnumerable< Person> person;When the page postsback, the person list is null. How can I retain the values of person list without declaring it as static? Sr. devs in my company say that you should not declare the list as static.
When the finish button is clicked on the third step I would like to Create the user and send the form. I have the logic for this written but the only problem I have is the when the next button is pressed on a wizard, a PostBack occurs and my password field:
We currently have a page with several user controls (8 of them) and when a control that is contained in an updatepanel initiates a postback the focus is not retained. In some cases, it looks like the focus is sent to the top of the page, and in other cases the focus looks like it is sent to the control with the TabIndex=1.
I have tried 3 different solutions and they all end up with the same result.
The first two were from article: [URL]
Solution 1: At the end of the server event executed in postback, add:
The article says both of those solutions worked, but for us, neither of them did.[Code].... ASPX.CS
In all 3 scenarios the control we want to have the focus gets the focus for a split second and then the focus is cleared (set to the top of page, or TabIndex=1).
This is a problem I'm facing in a webapp I'm currently working on. So instead of cluttering the question with unrelated code, I recreated the problem in an isolated, simplified webapp that only demonstrates this issue.
I have a web user control with just this as its content:
When you click btnSwitch, it simply switches to the second view with the user control. Notice how I have the ShowAlertScript already initialized to true. The potential output is that since I'm "showing the alert script" within the user control, the AlertMe() function will execute when you click the input-button element, because it's written out according to the inline if statement.
If you run this code I gave you so far as is, it will not work. The browser will say it can't see the AlertMe() function; it's undefined as far as it knows. But if you take out the UpdatePanel (or disable the ScriptManager's partial rendering), it will work just fine on a full postback when you click btnSwitch.
In turn, you might also be concerned that if I have more than one instance of the control, I end up with copies of the same script. Not really; there will only be ONE input mode of this control in a page at any given time, it's just that I have those two modes in two separate views and I let the user switch between them.
I have the example working but I added a Select Command to the Detail grid for the purpose of selecting a detail record which will redirect to another page. The problem is that when the Select command is clicked the expanded detail grid collapses as if I had clicked the minus. The page and codebehind are:
The graphic designer of a project I'm building a web site for chose jquery.tools [URL] for a tabs tool in the site. Unfortunately it seems that the tool doesn't behave properly on a postback in IE7 or IE8 (it does behave properly in FireFox, Chrome and Safari). Does anyone have experience using the jquery.tools with asp.net? and know how to retain the tab index on a postback? I've tried a lot of things and can't get it to work. The code i'm using now is as follows:
$("ul.tabsScenario").tabs("div.panes > div"); var tabIndex = $('#ctl00_ContentPlaceHolder1_EnInDeToekomst1_HiddenFieldTabIndex').val(); $("ul.tabsScenario").tabs('select', tabIndex);
where the tab index is stored in a hidden field (HiddenFieldTabIndex). The above code works fine in Firefox, Chrome and Safari, but not in IE7 or IE8. I am using a ScriptManager and UpdatePanels, but in an extremely simple website example I can't even get the jquery.tools tabs tool to work. There are some unanswered posts on the Jquery.Tools forum concerning this topic, but yeah, that doesn't help much. I've already determined that the jquery.ui tabs tool works well after a postback but that would cost a lot of refactoring in our project as far as html and css goes. I'd like to avoid that.
I have a Calendar Control that I added text that show scheduled meetings on certain dates and it works okay. The problem is that when I click on a date I need to http to another web page or sometimes goto a web page in the same web site. The problem is when the code that creates the hyperlink runs it replaces the text displaying "meetings" scheduled for that date instead appending the link to the date and retaining the "meetings" text that was already there.
Below is how I set that up with the code that adds the meetings followed by the url code that replaces the meetings text:
or any other kind of link in my Calendar Control without clobbering whatever was in there? If it is not possible is there another way to link to another page after a date in the Calendar Control is clicked?
