Add A Confirmation Dialogue Window Before Deleting The Record

Mar 14, 2010

I have a dropdown list, and can select names to delete from db table user.

Just want to add a confirmation dialogue window before deleting the record.

I am using a simple function at js to confirm. Isn't that enough to go to btnDelete_click() if true? I am using LINQ to SQL.

I tried:

(code behind)

protected void Page_Load (object
sender, EventArgs e)
{
if(!IsPostBack)
btnDelete.Attributes.Add("onclick","return check();");
}......

Web Forms :: How To Show Confirmation Message

Jan 24, 2011

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.

Explicit Localization - Translate The Confirmation Message To Norwegian

Mar 2, 2010

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.

Web Forms :: Include A Confirmation Message Upon Check Out Of Websore

Feb 25, 2011

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?

Web Forms :: Popup Customized Confirmation Message, Then Do Postback?

Jan 27, 2010

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.

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.
