I am working on a project in which I am binding Cart:
As shown in image I am populating my cart. Using User Control. And in User control I have populated that using One simple aspx form that is minicart. So now as you can see there is one button Checkout in That page. Which is populated through User Control but actaully its inside my minicart form. So now if I am trying to redirect using that Checkout link button. But that is not calling my click event rather its just postback the page.
Basically I want to call aspx page's click event through user control in my another aspx page.
I have tried to call that click event through many ways. But still page is only doing postback. I just want respose.redirect to my checkout page.
Even I have tried by using <a> also:
<a id="lnkcheckout" runat="server" href="javascript:return false;"
onclick="checkout_onclick">Checkout</a>
But not succeed..
Don't go for a server side for only redirecting you can take one achor tag also
<div align="right" style="padding-top: 10px;"> <a id="lnkcheckout" href="checkout1">Checkout</a> </div>
And it will work :) I hope this will help you
Try to use event.preventDefault() or use return false like ,
jQuery(function(){
jQuery(document).on('click','.morebutton', function(e){
e.preventDefault();
alert('ok');// you code in place of alert;
});
});

I am developing a website using asp.net/C#
I want to create a button that can save user data then move to a div tag at the same page.
I already did the saving part, but how do I make the same button to navigate to a different div tag within the same page?
some people use the response.redirect method to navigate to a different page. I want to navigate to a div tag within the same page. For example:
Experience
after I press that it will take me to:
<div class="panel" id="experience">
I want to do the same but with button that can do both that and saving to a DB. As I said, I already did the saving part.
I tried this:
<asp:Button ID="Button1" runat="server" Text="Save & Continue" OnClientClick="#experience" OnClick="Button1_Click" />
But it didn't work.
any ideas? I am trying to access that div tag from code behind
If this is WebForms and you don't want to use javascript, then, after you do the save, you can do a Response.Redirect to the same url, but with the anchor tag, e.g. Response.Redirect("myPage.aspx#experience").
This really depends on the rest of your code though. I suggest posting the relevant parts of your code behind so that we can better see what you have done. Also, don't try to avoid javascript - it is too useful to avoid.
ASP.NET has a Focus method that can be applied to the following ASP.NET server controls:
Button
LinkButton
ImageButton
CheckBox
DropDownList
FileUpload
HyperLink
ListBox
RadioButton
TextBox
At the end of your Button1_Click event handler code-behind, add something along this lines of this:
TextBoxExperience.Focus();
Note - The TextBox control with ID of TextBoxExperience control would be inside of the experience DIV.
I have two button in my cshtml page. When i click the first button data fetch from the database and bind it my controls. The records are many so the second button goes down, then i click the second button same thing happened fetch from the database and bind the grid, so the page is loaded then the page goes up. I want to stay same place when i click the second button. How to prevent it.
make your button like this :
<input type="button" id"button2" onclick="CallAjax();return false;"/>
//then in javascript
function CallAjax()
{
//your ajax call here to retrieve or update data
}
This is MVC 101...
Make your button a standard HTML5 button, which calls a JavaScript function on click...
<input type="button" id="goButton" value="Go »" onclick="goFunction();">
(I don't think you have to "return false" with a button, only with a submit)
Then, use Razor helpers in your view to do the Ajax call to the controller...
function goFunction() {
var url = '#Url.Action("MyActionMethodName", "MyControllerName")';
var settings = { 'some data': 'some values' };
$.ajax(url, settings);
}
See the JQuery Ajax page for more information about how to work the "settings" object.
BTW - sounds like you are "paging a grid" but you just forgot to say so... use a tool for that, such as Kendo. Paging is solved, don't solve it again.
I am new to the ASP.NET world and I need to do a popup to select some data.
The idea is that the user can select one or more options with a CheckBox. When he presses a button a popup appears with a list of options loaded from the database.
I don't know how to create a popup with those options and receive the selected options when the popup close. But I know how to do the option list from the database with a repeater.
there is no such popup control in ASP.NET.
However there are numerous 3rd party plugins, which provide popup controls.
ajax tool kit model popup extender
jquery built popups
you can create your own. popup is nothing but a hidden container, which appears upon some action, and whose location and background is as per your choice.
create a popup like this:
<div class="parent">
<div class="popup">
</div>
</div>
<input type="button" value="popup" id="btnpopup" />
and css
.parent
{
position:relative;
background-color:#CCCCCC;
width:200px;
height:200px;
}
.popup
{
width:50%;
height:50%;
position:relative;
top:20%;
left:20%;
background-color:#DDDDDD;
display:none;
}
and jQuery code
$('#btnpopup').click(function(){
$('.popup').toggle(200);
});
see this fiddle
You can use the OnClientClick of the button to open the popup. Depending on it being a normal browser popup or a jQuery dialog you have two general options:
Standard Popup
Standard popups open as if they are a separate page. When you click OK you may have to store the selection into the user's session if the data is needed on the page that triggered the popup, or store it directly in the database. If the former is the case, when you return to the page and submit it, the data from the popup will be available in the session to process.
jQuery Dialog or particularly any js-triggered html dialog. You can show it with the corresponding js again in the OnClientClick function, and perform the selection. On the OK button click of the dialog almost nothing is needed (except hiding it). Since the dialog input controls are part of the page, they will be posted on submit and be process-able on the server.
That's basically all you need to do, but some more reading on the topic won't hurt. Good luck.
Hi everyone I have a web form in which I am having a button on clicking which data back up is being taken, I used the following javascript :
<script language="javascript" type="text/javascript">
function showPleaseWait() {
document.getElementById('PleaseWait').style.display = 'block';
}
</script>
<asp:Button ID="btnTakebackup" runat="server" Text="Take Backup" Enabled="true"
onMouseDown="showPleaseWait()" CausesValidation="false" />
<div id="PleaseWait" style="display: none;">"Please Wait Backup in Progress.."</div>
Hi I am using a button to take a back up.
Now I want to show a message in btnTakebackup_Click() event, whether Back up was successful or not.
I used Response.Write("<script>alert('abcd');</script>"); in btnTakebackup_Click() event.
But the problem is that I want to show the page also, which is not showing instead white background is showing.
Thanks in advance...
To show a message box alert should be able to write out a new script to the response stream:
var script =
"<script type=\"javascript\">" +
"alert(\"Backup in progress, don't go!\");" +
"</script>"
Response.Write(script);
However much this is distasteful, I suppose it is sometimes "necessary".
You can add client side event handlers to ASP controls:

Cheers.
Do you really want it to be an alert? (You should know that they lock up the whole browser not just the tab your page is on), do your users really need to acknowledge the backup success by clicking ok or just be informed of it?...
I suggest you have a div on the page that says "Backup successful". The visibility of which can be set by a boolean property BackUpSuccess which you can set to true in the code behind you mention.
<div id="backUpSuccess" <%=BackUpSuccess ? "" : "style='display:none;'"%>>
Backup was successfull
</div>
...you can style the div as you like in your .css file to get attention.
If you really do want an alert you could run some JavaScript on page load to check the content of a hidden input that you set server side in similar fashion...but running javascript on page load is tricky...unless your using jQuery and then you will know it's very easy.
From your question, I understood that after clicking on the button, the data back up is happening, but the alert is not displaying as soon as you clicked the button.This is because you are calling the JavaScript in the button click event which will be fired only after all the code in the button click is executed.I suggest you to add a JavaScript function in the .aspx source page it self and call the JavaScript function as shown below:
<script ...>
function xyz()
{
alert('Please Wait');
}
</script>
and in button declaration
<asp:button id='btn_submit' runat="server" OnClientClick="return xyz();" />
Wondering if there is a way upon clicking on a hyper link to set drop downlist to visible in code behind or asp?
<asp:HyperLink ID="HyperLink2" runat="server">View More Workout Programs »</asp:HyperLink>
If you have to do it in code-behind, then use a LinkButton instead of a HyperLink. Then it will have a click event just like any button and in that click event you can set the other element to .Visible=true.
However, does this need to be done in code-behind? Keep in mind the difference in "visibility" between server-side and client-side code:
If set to .Visible=false on the server-side, the content is not delivered to the client at all.
If set to display:none on the client-side, the content is present and can be viewed in the page source, it's just not displayed by the browser.
In some cases, the former is needed for security purposes. But if it's just a matter of user experience then I would recommend showing/hiding the content entirely on the client-side so as to avoid post-backs that do nothing more than change element display properties.
For example (assuming jQuery):
<a id="toggler" href="#">Show the content</a>
<div id="hidden" style="display:none;">Content</div>
<script>
$(document).ready(function(){
$("#toggler").click(function(){
$("#hidden").show();
});
});
</script>
Use an asp:LinkButton instead of a hyperlink and handle the OnClick event. In the OnClick event, toggle myDropDownList.Visible depending on whether you want to show it or not.
You should implement that kind of feature in the client (javascript code) to improve user experience.
Anyway, you can use a Panel with Visibility=false and put Visibility=true in code behind when link is clicked. You would need to adjust the position of that panel with css to look like a dropdown.
You can try with JQuery : http://www.jquery.com
It will be something like
<script type="text/javascript">
$(document).ready(function(){
$("#<% =HyperLink2.ClientID %>").click(function() {
$("#<% =DropDownList1.ClientID %>").toggle();
});
});
</script>
If you need to send form back to the server, use asp:LinkButton instead and handle OnClick event on the server side. If you need to show drop down list on the client side, use javascript function with onclick client event to show or hide any section you want.
