I have an asp.net web page with asp:button control. I need to show two (normal) HTML buttons for the click event of the asp:button control.
My requirement is when the page load for the first time there will be only asp:button there visible. After I click on that asp:button other two HTML buttons should be visible. But they should be visible for all the other postbacks. I mean if there would be any post backs, that HTML buttons should be visible constantly. How could I do that? Please help me. I tried to implement that using jquery hide and show.
You can use <asp:Button> controls for the other two buttons, and can set Visible="false" initially, then setting Visible="true" when you need to show them. This way, the server can do everything, and retain viewstate too so you don't have to reshow the buttons everytime the page posts back.
ASP buttons are standard buttons but can trigger the functionality you want through the OnClientClick property:
<asp:Button .. UseSubmitBehavior="false" Text="Move up" OnClientClick="moveSlider(1);return false;" />
<asp:Button .. UseSubmitBehavior="false" Text="Move down" OnClientClick="moveSlider(-1);return false;" />
Using return false; makes sure that the button doesn't postback, and UseSubmitbehavior="false" renders an <input type='button' /> instead.
HTH.

I have one asp button I want avoid pageload on button click
Plz someone help
Even JavaScript method will be ok for me
The framework fundamentally does not work that way. If you stay true to the framework, you can wrap your button in an update panel. That will remove the visible postback, but that will still fire the postback and perform the page load and click event.
In essence the update panel will dump your entire page into memory, then reload only the differences, simulating an ajax request.
The link submitted only allows the button to perform a JavaScript function, which would still need to Ajax to the backend.
<asp:UpdatePanel ID="upSample" runat="server" ...>
<ContentTemplate>
<asp:Button id="btnSample" runat="server" ... />
</ContentTemplate>
</asp:UpdatePanel>
Otherwise you should not use a server side event at all, simply do traditional html <input type="button" click="btnSample_Click()" /> that is actually doing Ajax directly to the server side.
im trying to hide div by clicking the button, but it does hide it for a second and return the div (looks like it refreshing page).here is my html code :
<div id="page">
<p>First Paragraph</p>
<p>Second Paragraph</p>
<p>Yet one more Paragraph</p>
<asp:Button ID="Button1" runat="server" Text="Button" />
</div>
and here is my jquery code:
$(document).ready(function () {
$("#Button1").click(function () {
$("#page").hide();
});
});
What Rick said in his answer AND you need to add Type="Button" to your button.
<Button ID="Button1" type="button">Button</button>
The default button type is submit, which will cause the page refresh. AND, as Rick mentioned, ASP buttons will also submit. So, you need to use an HTML button and set the type="button" attribute.
From MDN
The type of the button. Possible values are:
submit: The button submits the form data to the server. This is the default if the attribute is not specified, or if the attribute
is dynamically changed to an empty or invalid value.
reset: The button resets all the controls to their initial values.
button: The button has no default behavior. It can have client-side scripts associated with the element's events, which are
triggered when the events occur.
An ASP Button with runat="server" causes a server post-back. If you aren't going to be acting on that click from the server, just use a client-side button like:
<button id="Button1" type="button">Button</button>
Set the client id mode to static on the button, then it'll work. It's not working because that hasn't been specified so the name is changing.
<asp:Button ID="Button1" ClientIDMode ="Static" runat="server" Text="Button" />
If you wanted to disable the postback to simply hide something without processing anything, then just using a client side button is the best option.
I have 3 different submit buttons(Log In, Search, Insert) in the same page and what I want is to find the best way to have this 3 buttons doing a different things when I press them, or I press enter while I am about to press them.
As you can see from my photo, when I press Log In the Insert is pressed too because I have a global form in my Master Page.
I tried to use different forms, but i can't because I need them to have runat="server", which is not possible for a page to have.
I use asp Texboxes:
<asp:TextBox class="text-input" ID="txtLoginEmail" runat="server"
Height="15px" Width="130px"></asp:TextBox>
and asp Buttons:
<asp:Button class="submit google-button" ID="btnLogin" onclick="btnLogin_Click"
runat="server" Text="Log in" />
except my Search button which is linkButton:
<asp:LinkButton ID="searchLink" runat="server" onclick="searchLink_Click">Search</asp:LinkButton>
You may use Validation Groups to cause only required text boxes validation on specific button click. And then in event handler to concrete button you may execute specific logic.
I have two UpdatePanels. One UpdatePanel has a CheckBox and a UserControl. UserControl has some TextBoxes. In other updatepanel, there are few Labels.
I have added javascript function to checkbox to hide/show it. I am using Javascript to avoid partial postbacks to server.
I also want to update the second UpdatePanel when checkbox is checked/unchecked or some data is changes in user control's textboxes.
Can I call javascript function as well as server side function on same checkbox ? I tried adding triggers to second updatepanel but they are not fired.
updatepanel1
checkbox
usercontrol
textbox1
texbox2
updatepanel2
label1 (updated on change of textbox 1)
label2 (updated on change of textbox 1)
my checkbox markupd looks like this
<asp:CheckBox ID="chkShippingSameAsBilling" runat="server"
Text=" Ship to same address"
AutoPostBack="true" Checked="true"
onclick="return ShowShippingAddress();"
/>
You can add a dummy button on the page. Set async postback trigger for the second panel on the button.
<asp:AsyncPostBackTrigger ControlID="btnAsync" EventName="Click" />
In the check changed of the check box, in javascript call function
btnAsync.Click();
It will postback the second update panel asynchronously. You can call server side functions from second panel postback or by adding server side click event to dummy button.
Put a hidden button in your second updatePanel:
<div style="display:none">
<asp:Button ID="YourButton" runat="server" />
</div>
Then click in using your onclick function:
function ShowShippingAddress()
{
document.getElementById('<%# YourButton.ClientID %>').click()
}
That should cause the second to postback and update.
You will need to set up a trigger in the second panel to use the event from the checkbox, there are some examples here.

Trigger an update of the UpdatePanel by a control that is in different ContentPlaceHolder
Also, take a look at knockout.js or jquery for some more elegant solutions...

I have an asp.net web page that displays data that was returned from the database. However, when I attempt to click "Reset" (<input id="btnReset" type="reset" value="Clear" />) the button doesn't do anything.
The reset button will only erase the data the user entered after the page was rendered. So if you dont make any changes in the page, the reset button wont do anything.
Also, Reset is a client side operation. it wont post-back the page to the server.
you are probably looking for this
<asp:Button id="btnReset" Text="reset it!" runat="server" onclick="btnReset_onClick" />
so you can do stuff in your codebehind
