Pass A Confirmation Or Error Message Back To A View?
Mar 2, 2011
When the user clicks the submit button on a form I want to return a success / failure message to the user and i'm wondering what the best way to send the message back to the user is.
For example on a login form if the user enters an incorrect password i'd want the view to reload with a message telling them that login failed. Or on an update form the original view they had would show up with a message saying update was successful.
My idea is to have a few partial views or HTML helpers that look for a ViewBag property like "ErrorMessage" or "SuccessMessage" and conditionally show themselves when these properties have a value. These components could be added to the _Layout or manually each form where they are required.
Edit
I have since found out that the ValidationSummary method takes a parameter of whether to exclude property errors which means you can use it to show when login / registration has failed. But there seems to be a bug where the validation summary is still generated even if there are no errors.

I'd like to get the message number and severity level information from SQL Server upon execution of an erroneous query.
For example, when a user attempts to delete a row being referenced by another record, and the cascade relationship is "no action", I'd like the application to be able to check for error message 547 ("The DELETE statement conflicted with the REFERENCE constraint...") and return a user friendly and localized message to the user.When running such a query directly on SQL Server, the following message is printed:
Msg 547, Level 16, State 0, Line 1
<Error message...>
In an Asp.Net app is this information available in an event handler parameter or elsewhere?
Also, I don't suppose anyone knows where I can find a definitive reference of SQL Server message numbers?

I want to pass a message from the controller to a view using Viewdata. Here is my code:
public ActionResult Create(FormCollection createPage)
{
try
{
......................
ViewData["Message"] = "Success - rec added!!!!" ;
return RedirectToAction("Index");
}
catch (Exception e)
{
ViewData["Message"] = "Exception: " + e.ToString();
return RedirectToAction("Index");
}
On my View I have:
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>::><%: ViewData["Message"] %><::</h2>
<h3>==><%= ViewData["Message"] %><==</h3>
<p>
This is Index.aspx page in Controller folder
</p>
</asp:Content>
I am getting result with empty ViewData["Message"]

I have a simple model where a Person has Gifts. I have a view which is a list of Gifts belonging to one Person.
My problem is with the Create action for a new Gift. I want it to default to the PersonID that we are already viewing the list of Gifts for. I tried simply passing the last PersonID (they are all the same)
Html.ActionLink("Create New", "Create", new { id = Model.Last().PersonID }) which works fine if there is already at least one Gift for that person but if this is the first Gift I don't have a value.
My Gift List controller knows the PersonID I want to pass but the view doesn't.
How do I pass this PersonID from my Gift List controller to my Gift Create controller via the Gift List view? Or is there a better way to do this?

I used to be able to view the pages of my ASP.NET 3.5 website locally via the 'View in Browser' facility. However, this no longer works (for any page). All I get is a 'HTTP 404 Not Found' error message.
Where might I have screwed things up?

I have one page which contains 3 panels and 3 buttons. Each panel connects one button. When one button clicks, the relative panel appears and other panels are divisible. For each panel, I design a textbox, a merge button and a gridview. When user input information into the textbox, the gridview shows the detail data from the database and two checkboxes. The next step, user uses checkboxes to choose two different rows of data and click the merge button. I need to show a confirmation message based on the selection user made i.e. Are you you want to merge A to B.
write the code to show the confirmation message which is works perfectly in Page_Load() method. But the problem is the page contains 3 panels. Do I need to write code for each panel to show the confirmation message and put 3 sets of the code in Page_Load?
see my code below.

I have a button in my gridview recurring through the rows which requires confirmation before it deletes a record. Instead of it asking, "are you certain you want to delete this contact?" I want it to specifically ask the user, "are you sure you want to delete <the name of the contact>?" This is the button that I have at the moment and I have no idea how to place the contact's name in there:

I have almost completed a competition entry form however i now find myself stumbling over a label which is to display a confirmation message that the entry has been received.
Stepping through the code using debug/breakpoints shows that the code is running the cycle but the end result of the form is just blank fields.

l.Attributes.Add("onclick", "javascript:return " & "confirm('Are you sure you want to delete this record " & DataBinder.Eval(e.Row.DataItem, "CategoryID") & "')")

Here we have a function The 'ConfirmDelete()' which is executed each time a click event occurs on the page.
2. Then we use a logic that to find which element was clicked on i.s we append a word 'DELETE' to the ID of the control.
3.And finally check if the clicked element having ID is 'DELETED' , then the javascript function will be execute to ask the user about his/her confirmation.
JavaScript code:

when trying to translate the confirmation message to Norwegian i get the following error: Cannot have more than one binding on property 'OnClientClick' on 'System.Web.UI.WebControls.LinkButton'. Ensure that this property is not bound through an implicit expression, for example, using meta:resourcekey. i use Explicit localization in the following manner:
<asp:LinkButton ID="lnkMarkInvoiced" runat="server" OnClick="lnkMarkInvoiced_OnClick"
OnClientClick="<%# Resources: lnkMarkInvoicedResource.OnClientClick%>"
Visible="False" CssClass="stdtext" meta:resourcekey="lnkMarkInvoicedResource" ></asp:LinkButton>
here's the local resource file entry:
<data name="lnkMarkInvoicedResource.OnClientClick" xml:space="preserve">
<value>return confirm('Er du sikker?');</value>
if i remove the meta attribute i get the English text(default). how do i get the Norwegian text appearing without resorting to using the code behind? Update: removing the meta attribute prevents the exception from occurring but the original problem still exists. I can't get the Norwegian text to show. only the default English text shows.
Another Update: I know this question is getting old but i still can't get the Norwegian text to display.

I want to include a confirmation message upon check out of my websore. I have already included it in the load statement and the message box appears as intended. I still don't know how to obtain the value (true or false) so that I can continue with check out or return to page. I've been reading a lot about using scripts, but all the scripts that I've seen are in the main aspx page and not the code behind page. I'm using VB2010. give me an example of using code behind page in VB to filter the result of the confirmation box?

I have the following situation I am having trouble with.
1) Users select some items from a checkbox & type a message in a textbox
2) The user clicks on a message preview button
3) Based on what they had selected, a message will be created. This message is stored in a database
4) I am using showModalDialog to display their message to the user.
5) The user is given two options, send & cancel
**Here is where the problem starts**
6) If the user clicks send, I want to call a server side method that sends this message to a portal (method already developed) I was trying to use "__doPostBack....", but this is throwing a javascript error.
