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 :: FileUpload Control - How To Maintain Client Directory Path On Postback
May 4, 2010I'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.

Sep 30, 2010I 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

AJAX :: How To Retain Focus After Postback (updatepanels)
May 14, 2010We 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]....

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).
Javascript - How To Retain Script Block On A Partial Postback
Nov 20, 2010This 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:
<% if (ShowAlertScript)
{ %>
<script type="text/javascript">
function AlertMe()
{
alert('Hello World!');
}
</script>
<% } %>
<input type="button" onclick="AlertMe()" value="Say Hello" />
And its codebehind has nothing more than the boolean definition of ShowAlertScript. This represents a control I have in the big webapp that has two modes: input mode, and display mode. When in input mode, it has a large javascript block that is only useful then; it does some cool stuff to help the user input the info.The way this control is laid out in the big picture is as follows:
<asp:ScriptManager runat="server" />
<asp:UpdatePanel runat="server">
<ContentTemplate>
<asp:MultiView ActiveViewIndex="0" runat="server" ID="mvw">
<asp:View runat="server">
<asp:Button runat="server" ID="btnSwitch"
OnClick="btnSwitch_Click" Text="Switch" />
</asp:View>
<asp:View runat="server">
<uc:MyInputControl runat="server" ID="micInput" ShowAlertScript="true" />
</asp:View>
</asp:MultiView>
</ContentTemplate>
</asp:UpdatePanel>
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.
I want it to work on a partial postback, because this whole thing is a small piece compared to the rest of the page, and I don't want to do a full postback every time they switch views. Apparently, the ScriptManager doesn't even bother re-rendering the ascx file for possible changes. Either the ScriptManager is not smart enough, or there is an option I'm missing to let it render the <script> so I can invoke its methods on the client side. A potential answer someone might suggest is "why don't you take out the javascript, put it in its own .js file, and have the page reference it so it's available to the control?"
That won't really work with me, because the script block does some initialization and modification that pertain to that single control instance, not to all others on the page.
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.

JQuery :: Tools Tabs Doesn't Retain Tab Index On Postback
Sep 6, 2010The 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.
Web Forms :: How To Set A Link In Calendar Control And Retain Text In The Control
Oct 14, 2010I 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:
[code]...
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?
