Give a message to save in formview

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :ASP.Net
I have a web page where I have formview and grid view. The formview's default mode is in update mode. The user needs to enter a value or modify a value and then needs to click update button. I want to show them a message when they enter or modified something but not clicked the Update button. The message will be like: "Do you want to save the changes?" What is the best way to do this? Thanks in advance.

Secure It: WS-Security and Remoting Channel Sinks Give Message-Level Security to Your SOAP Packets


As more organizations adopt XML-based Web Services, the need for message-level security has become evident. WS-Security, now supported in the Microsoft .NET Framework, addresses this need. Using the WS-Security framework, developers can implement channel sinks to intercept Remoting messages as they pass through the .NET Remoting infrastructure. The sink can read the message, change it, and pass it along. During this process, the message can be signed for added security. This article explains how to implement a Remoting channel sink that will modify the Remoting message by including a UserName token in the header, then sign the body using the token.

Getting 'The page took too long to save' message.

Hi there.

I'm using a SharePoint site that all of a sudden is now throwing 'The page took too long to save' messages when I try ot save an ASPX page in the edit mode. This was not happening yesterday.

I understand that this could be due to a number of other elements, but has anyone else experienced this issue and found that it was something particular at fault?

Also I have been getting the message 'Please wait while script are loading...' appearin the status bar for IE. There's no reason why the page should take so long to render, but again if anyone else has a suggestion as to why this is occurring, then any help would be appreciated.

Storing binary objects (such as image, office document etc.) into database is a little cumbersome when it comes to retrieval. Hence the most commonly accepted way is only store the file path in the database, and to store the documents on a file share.

Inserting personal error message in ValidationSummary



I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator. 

My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary. 

Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.

This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

Thanks in advance

Formview LinqData source not allowing updates


OK, I'm confused.  I've set up a formview with a Linqdata source to allow users to edit records.  When I run it, edit data and submit, it blows up and tells me "Linq datasource6  does not support the Select property when the Delete, Insert or Update operations are enabled."  I googled that warning and saw a couple of posts on this forum saying the problem is the slect statement has to be removed from the Linq data source for it to allow updates. 

But if I remove the select statement then how do I show the user specific info on pageload?   plus I thought the two way databind was an advantge of the datasource control.




could somebody give me example how I can connect to database only once if I use many models in contr


I use in my ASP.NET MVC application repository pattern and I use in controller for example 3 models:

   namespace MvcApplication1.Controllers  
        public class HomepageController : Controller  
            private IWebsitesRepository _repository_websites = new WebsitesRepository();  
            private IFirmRepository _repository_firm = new FirmRepository();  
            private IPhotosRepository _repository_photos = new PhotosRepository();  

In WebsiteRepozitory, FirmRepository and PhotosRepository classes I have:

Database1Entities _entities = new Database1Entities();

So I have 3 connections to database ? Is it wrong ? How can I solve it ?

UpdatePanel is not a known element - message when upgrading to 1.0 ajax


It worked on one of my old pages.  I change the web.config, renamed all the <asp.

On some aspx page it doesn't recognize the updatepanel.  It only does on one page.  If I create a new aspx page with a different name - then it works.

Should I just create a new web project ajax - then copy all my code into there?  Or is there a way to get those old pages to recognize the new ajax controls?

Profile not being save after redirect.



I am trying to save values into a Profile on Page1, then redirect to Page2 and access those values.  However, after the page redirects the profile values are blank as if they were never saved.   When stepping through the code I can see that they are being save on Page 1.

I suppose I could use session variables to store the information but I don't understand why saving the profile doesn't work.

private void PayWithPayPal()
        ProfileCommon profile = this.Profile;

        if (Global.CurrentUserName.Length > 0)
            profile = this.Profile.GetProfile(Global.CurrentUserName);
        profile.FirstName = uxFirstNameShipping.Text;
        profile.LastName = uxLastNameBilling.Text;
        profile.ShippingAddress.AddressLineOne = uxAddressLineOneShipping.Text;
        profile.ShippingAddress.AddressLineTwo = uxAddressLineTwoShipping.Text;
        profile.ShippingAddress.City = uxCityShipping.Text;

Very Basic Question - Error message running first page


Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!


I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).


Appreciate any help I can get!

FormView -- Parameters and asp:Table


I've already solved this problem to my satisfaction, I just want to know WHY it works this way.

I have a FormView control bound to an ObjectDataSource.  Let's say our data source is a hypothetical table with three columns:  id, name, age.  Why is it that when I use the <asp:Table> element inside of the FormView, the parameter values are not set, but when I use the standard <table> tag, it works fine?

This seems like a .NET problem to me.  I expect the <asp:Table> element to work in the same way as <table> because they are, for all intents and purposes, the same thing.  Am I missing something?

DropDownList within FormView Error

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
