POIs there any native way in ASP.NET to do a "success message"?
text
Body
copied!<p>Say you have something like an ASP.NET ASP:DetailsView to show and edit a single record in a database.</p> <p>It's simple to record the error cases... you add validation and a validation summary. When your update form fails validation it naturally makes noise: it shows the validation message and/or the validation summary. Not a single code behind is required.</p> <p>But then, you pass validation, and it makes your update completely silently. There's no sense that anything happened, and there doesn't seem to be any default settings to make a success message without code-behinds.</p> <p>But, even code-behinds are confusing. What event should show the success message? onItemUpdate, right? Fine, but then let's say you make another change and get a validation error? Your success message stays. I wasn't able to find an event that would reliably turn off an existing success message if there were a validation error. </p> <p>This should be web development 101! Why is it so hard?</p> <p><strong>EDIT:</strong></p> <p>Someone suggested using the ItemCommand event... I tried this and many other events, but that success message just won't disappear. Here's some code.</p> <p>My message in ASP.NET</p> <pre><code><label id="successMessage" class="successMessage" runat="server"></label> </code></pre> <p>And my DataView tag (simplified):</p> <pre><code> <asp:DetailsView Id="EditClient" DataKeyNames="LicenseID" DataSourceID="MySource" runat="server" OnItemUpdated="SuccessfulClientUpdate" OnItemCommand="ClearMessages"> </code></pre> <p>And, my code-behind:</p> <pre><code>protected void SuccessfulClientUpdate(object sender, DetailsViewUpdatedEventArgs e) { successMessage.InnerText = string.Format("Your changes were saved."); successMessage.Visible = true; } protected void ClearMessages(object sender, DetailsViewCommandEventArgs e) { successMessage.InnerText = string.Empty; successMessage.Visible = false; } </code></pre> <p>Once I do a successful update, however, nothing seems to make that message disappear, not even failed validation.</p> <p><strong>2nd EDIT:</strong></p> <p>Just want to be clear that I did try putting the ClearMessages code in Page_Load. However, nothing seems to make that successMessage label disappear when I hit update a 2nd time WITH a validation error. Can anyone suggest any other troubleshooting tips?</p>
