Hi,
I am implementing auto complete extender in my project. I want a loading image to be displayed in the textbox while the data is being fetched from database and presented to the user.

<asp:TextBox id="TextBox2" Width="216px" runat="server" Text='<%# Bind("c_name") %>'  autocomplete="off" ></asp:TextBox><br />
 <br />
 <cc1:AutoCompleteExtender id="AutoCompleteExtender1" runat="server" ServiceMethod="fetch" TargetControlID ="TextBox2" ServicePath="autocom.asmx"   CompletionSetCount ="12" EnableCaching ="true" MinimumPrefixLength ="2"> <br />
 </cc1:AutoCompleteExtender>

You can use AJAX UpdateProgress control to get that functionality. See here UpdateProgress control[^]

1st Approach

<script type="text/javascript">
function ShowImage()
{
document.getElementById('txtAutoComplete')
.style.backgroundImage = 'url(images/loader.gif)';

document.getElementById('txtAutoComplete')
.style.backgroundRepeat= 'no-repeat';

document.getElementById('txtAutoComplete')
.style.backgroundPosition = 'right';
}
function HideImage()
{
document.getElementById('txtAutoComplete')
.style.backgroundImage = 'none';
}
</script>

Now write this code in Page_Load event of aspx page

protected void Page_Load(object sender, EventArgs e)
{
this.txtAutoComplete.Attributes.Add
("onkeypress", "ShowImage()");
this.txtAutoComplete.Attributes.Add
("onblur", "HideImage()");
}

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

2nd approach

This approach works if you are using newer versions of AjaxControlToolkit.dll (Version 1.0.20229.20821 or later)
For this write the above mentioned javascript in head section of html markup of page.
Now in source of autocomplete extender add OnClientPopulating="ShowImage" and OnClientPopulated="HideImage"

<ajaxToolkit:AutoCompleteExtender runat="server"
ID="AutoComplete1"
BehaviorID="autoComplete"
TargetControlID="txtAutoComplete"
ServicePath="AutoComplete.asmx"
ServiceMethod="GetCompletionList"
MinimumPrefixLength="1"
CompletionInterval="10"
EnableCaching="true"
CompletionSetCount="12"
CompletionListCssClass=
"autocomplete_completionListElement"
CompletionListItemCssClass=
"autocomplete_listItem"
CompletionListHighlightedItemCssClass=
"autocomplete_highlightedListItem"
onclientpopulating="ShowImage"
onclientpopulated="HideImage">
</ajaxToolkit:AutoCompleteExtender>

<script type="text/javascript">
function ShowImage()
{
document.getElementById('txtAutoComplete')
.style.backgroundImage = 'url(images/loader.gif)';

document.getElementById('txtAutoComplete')
.style.backgroundRepeat= 'no-repeat';

document.getElementById('txtAutoComplete')
.style.backgroundPosition = 'right';
}
function HideImage()
{
document.getElementById('txtAutoComplete')
.style.backgroundImage = 'none';
}
</script>

GridView adds duplicate row on Page refresh

Hi,

I have a GridView with a FormView on its EmptyDataTemplate so that user can insert a row initially. I provide controls on Footer so that user can add rows from within the GridView. I also use inline editing and deletion. Datasource is SqlDataSource.

Problem is that when I refresh the page duplicate row is added with previous data in the grid footer controls.

I tried many ways to avoid it, I tried

Page.IsValid

(it returns true!), I tried to check for

e.Command == "insert"

, that too is correct. Even the

TextBox.Text

has values though it is empty after a manual insert operation.

What am I doing wrong here?

Regards,
Blumen

In the Insert command event,write the code which validates the data to check for the duplicates and then insert into the SqlDataSource. Update the gridview only if the transaction is successful.

Hi All,

On a button click event I redirect to a page as like this.

Response.Redirect("MyPage.aspx")

But it redirect to another page. Actually when I debug the code and see it working fine. But after hosting the size on IIS and access through the local IP url it doesn't work. Any suggestions?

I appreciate your help all the time...

The only thing this code can do, is redirect to MyPage.aspx. If you end up at another page, then other code is running, or that page is redirecting you again.

Two things may be wrong in this case:

(i) The hosted version may be different than the original one. So, check the code.
(ii) Check the other page where you are going to redirect. Is there any redirect code written inside the page load?

Calling another page in side a wizard control in asp.net

I have a wizard conntrol in my form. I need to call another page inside the wizard control and do some operation in one of the steps.

For eg: Form1 has a wizard control. After clicking Next button of the firt step or second step, it should go to another page, say Form2, and perform some operation and come back to Form1 itself. Is it possible to do that? Also if I want some value from From2 to Form1, is that possible?

Any idea how to do implment this? Please help.

Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

This sounds insane. You should factor out the action you want, to another class, or a control that can be used in two places.

I dont think it is possible to invoke another page within wizard control.
But if u want to navigate from one page to another and back to same page, i dont see any problem. Wizard control has nothing to do with.
And if u want values from page2 to page1, they are possible with sessions, query strings,..

As the title,when I do some changes in design view,the source view can not do the same changes.

We have a ASP.NET Menu control located within a Wizard control. When we change a property (e.g. Text) in a MenuItem, the change is effective in the design view, but is not sychronized to source view.

Product Language: English

Version: Visual Studio 2008 SP1

Operating System: Windows XP

Operating System Language: Chinese

Thank you.

Save your project, close Visual Studio 2008 IDE, reopen it, reopen the project. This sequence may solve this problem.

I wrote an article on how to use google, it's here on Code Project. You should read it. Sending an email is both so trivial, and so widely documented, that I used it as the example in showing how to find basic information on the internet.

ASP.NET also cannot send email, your website will use .NET code that does not depend on ASP.NET

Hi,

Here is a short example:

var smtp = new SmtpClient { Host = ConfigurationManager.AppSettings["smtpserver"]};

var mail = new MailMessage { From = new MailAddress("me@me.com") };

mail.To.Add(new MailAddress("some@email.com"));
mail.Bcc.Add(mail.From);
mail.Body = "Testing";
mail.IsBodyHtml = true;
mail.Subject = "Subject";
try
{
smtp.Send(mail);
}
catch (SmtpException)
{
//Error handling here
}

Hope that this helps.

Anyways, how to code if we set validation for email if it doesn't contain "@"?
