Posted By:      Posted Date: September 27, 2010    Points: 0   Category :ASP.Net

I am developing a web application in asp.net and c#. I'm using an asp wizard control. there is  6 wizard steps in my wizard. In each phase im using many controls, so that many postback is done during execution.
I am using a asp fileupload control in second wizard step. My problem is that the value selected using fileupload control is not getting when i click wizard finsh button in the final step. values acquired using all other controls are available there.
Hope someone help me.
I just want to get the selected filename in last step.

Cutting Edge: The ASP.NET 2.0 Wizard Control


ASP.NET has a lot to offer to both the low-level programmer willing to control every little step of the code and the busiest of developers who needs to point-and-click his way through Web app development using just a few existing components.

Problem with Wizard Control



I have a wizard, which contains a series of custom user controls as steps. Also I am using the step navigation template to add in the navigation buttons.

However, due to some steps needing a little time to load fully due to web service calls and having to add some dynamic steps, I would like to disable the navigation buttons until the next step has been loaded and change the text on the "Next Button" to "loading...". Is there away I can do this perhaps with JavaScript or is there away I could do this with an AJAX control? If so, does anyone have an example I could use?


FileUpload Control with membership and roles


Hi Everyone!

I'm pretty new to development using Microsoft technologies.

I'm trying to build a portal kind of an application in asp.net, in which one of the functionality is letting people log in and upload their documents. The upload page is only accessible to registered users of the portal.


I would like to track the user uploaded files according to their userIds.

Is it possible to use the FileUpload Control and C# to fetch the current user id, create a directory with the same name(as that of userID) in the file system and upload the files( multiple file upload, if necessary) into it?

Also another admin page would have to be able to see the list of files uploaded by the specific user and download it if necessary.

Could anyone help me with this?

I'm also expecting alternate solutions to the problem.

Awaiting a response.

Thanks in advance 


Why is there no wizard control in WPF? Is there an easy way to create one, like with the TabControl

Hello, First, NO THIRD PARTY PRODUCTS!  In my search, it seems like anyone asking for a wizard control is sent to a third party to buy it.  I have no interest in buying a third party product, so if you are one of those that would suggest it, please don't, I'm simply not interested. If my understanding of page framework is correct, that is, the page is within a separate XAML file and the events are handled via its code behind, then I am not interested in such a scenario.  Nor am I interested in any fancy plumbing to make page framework work the way I want. All I want is the simple wizard control.  I'm amazed that such an important function was left out of WPF, especially since the TabControl is so close to being a Wizard Control. I'm thinking that the TabControl should be able to be made to function like a wizard, but my search finds nothing of any value.  Is the TabControl not suitable to be made to function like a wizard? Any help (other than third party products) would be greatly appreciated. Regards, Robert

Wizard Control textbox data is lost

I'm using a wizard contol with several textbox fields. I have two textbox fields disabled (textbox19 and textbox20)because I don't want the user to change the values that are calculated from the other textboxes (see javascript below). I do this with javascript on the clientside. My problem occurs when the user is in STEP2 and goes back to STEP1 the values in the disabled fields are gone. Is there a way to fix this? I would also like to perform a validation on textbox20 but I haven't been able to do that with the textbox disabled. How can I do validations on a field that is disabled? I've tried enabling the fields and using readonly = true but that doesn't work either. Any suggestions? // Client Side script to do calculations <script type="text/javascript">       function calculateSubTotal() {      var txt6 = document.getElementById('<%= TextBox6.ClientID %>');     var txt12 = document.getElementById('<%= TextBox12.ClientID %>');     var txt18 = document.getElementById('<%= TextBox18.ClientID %>');     var txt14 = document.getElementById('<%= TextBox14.ClientID %>');     var txtSubTotal = document.getElementById('<%= TextBox19.Cl

FileUpload control loses value on postback.

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 FileUpload 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:protected void lnkbtnNext_Click(object sender, EventArgs e) { if (Session["pnl"].ToString() == "0") { /* other stuff code */ } else if (Session["pnl"].ToString() == "1")
