Um, I have this guy:
<div class="buttonRight"><asp:Button ID="btnOK" runat="server" Text="OK" Width="68px"/></div>
which renders out to
<div class="buttonRight">
<input type="submit" name="_$_$pc$pc$tabTO$_$uc0$popupSelectCompetition$btnOK" value="OK" id="____pc_pc_tabTO___uc0_popupSelectCompetition_btnOK" style="width:68px;" /></div>
I need to call some javascript on that button without altering its behavior otherwise. I tried putting an OnClick asp attribute but that seems to be for postbacks to call server code, not passing through a javascript hook to the rendered html.
I also don't understand how the input being type='submit' affects me.
Add your client-side code to the OnClientClick property :
<div class="buttonRight">
<asp:Button ID="btnOK" runat="server" Text="OK" Width="68px"
OnClientClick="alert('client side scripts here');"/>
</div>
OnClick property used for server side events.
Or add onclick attribute to your control like that at code behind :
btnOK.Attributes.Add("onclick", "alert('client side scripts here');");

In my asp.net website I have created a user control called GlobalHeader.ascx to make header content consistent throughout the website and put a text box control for search functionality as given below:
<div style="display:none;">
<form id="sample"></form>
</div>
<div>
<form id="cse-search-box" name="cse-search-box" method="get" action="/Search Results.aspx">
<input type="hidden" name="cof" value="FORID:11;NB:1" />
<input type="text" name="q" id="q" class="search-txt" onfocus="if(this.value=='Search')this.value='';" onblur="if(this.value=='')this.value='Search';" value="Search"/>
<input type="submit" name="sa" value="Search" class="search-iocn" />
</form>
Now in child page I'm having a drop-down control having AutoPostBack=true and OnSelectedIndexChanged="DrpdwnListSelectedIndexChanged" i.e. on item change event DrpdwnListSelectedIndexChanged is fired and and show some data just under drop-down list. BUT this functionality is ONLY work when I remove search functionality from Header user control.
<asp:DropDownList runat="server" ID="drpdwnList" AutoPostBack="True" OnSelectedIndexChanged="DrpdwnListSelectedIndexChanged">
</asp:DropDownList>
This means form tag preventing drop-down list AutoPostBack functionality to work.
Why so?
How can I make both functionality work together?
Interesting thing is that If I remove <form id="sample"></form> from top search functionality doesn't work.
Thanks
I am writing a simple webform on .net 4.0 framework.
<body>
<form id="form1" runat="server">
<div>
<span>Name</span>
<asp:TextBox ID="txtName" runat="server"></asp:TextBox>
</div>
<div>
<span>Email</span>
<asp:TextBox ID="txtEmail" EnableViewState="false" runat="server"></asp:TextBox>
</div>
<div>
<asp:Button ID="btnButton" runat="server" Text="Submit" />
</div>
</form>
</body>
Issue is when the form renders on browser, I am not getting ClientID for the server side controls. This is strange for me.
The portion of the markup in the browser is
<div>
<input type="submit" name="btnButton" value="Submit" id="btnButton" />
</div>
Notice there is no clientID.
Edit : Client ID something like 'ctl00$MasterPageBody$ctl00$btnButton2'
The client id of the button is btnButton. The other one "ctl..." is when you have your control inside a masterpage. As a side not: If you don´t wan´t asp.net changing your id:s you can set clientidmode='static'.
ClientID is a server side attribute.
You would see the ClientID on the client as the ID attribute:
id="btnButton"
Client id is calculated on the server, it never gets sent to the client.
You need runat="server" to generate a client ID for the control for the reasons mentioned
I got a request to add this form to a asp.net control.
I want to use asp.net text box and button to submit the info to the form. (because I have special controls to match the look and feel).
this is the form:
<form name="ccoptin" id="signup" action="http://visitor.r20.constantcontact.com/d.jsp"
target="_blank" method="post">
<input type="hidden" name="llr" value="yyyyyy">
<input type="hidden" name="m" value="xxxxxx">
<input type="hidden" name="p" value="oi">
<label>sign up for new services and promotions:</label>
<input type="text"name="ea" value="" class="text" />
<input type="submit" id="iframe" class="submit"
name="go" value="submit" />
</form>
can this be done?
yes, you can use asp.net Textbox control for html input control and you can put the same styling. e.g.
<asp:TextBox ID="ea" CssClass="text" runat="server"></asp:TextBox>
Button control for html submit button e.g.
<asp:Button ID="iframe" CssClass="submit" runat="server" Text="submit" />
For your input type hidden, you can use asp.net HiddenField Control
<asp:HiddenField ID="llr" runat="server" Value="yyyyyy" />
Yes it can be done . On browser side ASP.NET controls get converted in to HTML even if you use the asp.net button.
Drag and drop asp.net button from toolbox and put attribute id , cssclass , name , text . It will get converted in end to HTML as expected
<asp:Button id="iframe" cssclass="submit"
Text="Submit" runat="server" />
Yeah. You have to consider these notes:
If you want to use ASP.NET controls, you should add runat='server' attribute to your form element. It's because ASP.NET controls (AKA server controls) while rendering check to see if they are get rendered in a server form (VerifyRenderingInServerForm method).
<asp:Hidden control is your replacement for <input type='hidden'
<asp:TextBox control is your replacement for <input type='text'
<asp:Button control is your replacement for <input type='submit'
All of your server controls should have runat='server' attribute
ASP.NET only allows for one form with runat=server, and all of your server controls have to be within a form with runat=server. Nesting forms isn't advisable.
See reference on form nesting:
https://web.archive.org/web/20170420110433/http://anderwald.info/internet/nesting-form-tags-in-xhtml/.
You'll need the form in a different document object - maybe host it in an iframe and conver the mini-form to an ASPX page that you load into the iframe ...
I have a simple form that uses jQuery validation to notify the user of input errors, etc. When I add an ASP.NET CustomValidator to the form, it causes the page to postback and skip the jQuery validation. I need the form to not be submitted to the server until the client-validation is correct. Has anyone seen this before?
This is my form:
<form id="form1" runat="server">
<core:standardscriptmanager runat="server" />
<div>
<asp:textbox id="Email" name="Email" runat="server" cssclass="_RegisterFormValidate FormField Email {required:true, email:true, messages:{required:'You must enter an email address.', email:'Please enter a valid email address.'}}" maxlength="200" columns="75" width="98%" tooltip="Your email address"></asp:textbox>
<br /><br />
<core:recaptcha runat="server" />
<br />
<asp:linkbutton id="CreateAccount" runat="server" onclick="CreateAccount_Click" text="create"></asp:linkbutton>
</div>
</form>
And this is the core:recaptcha control that contains the custom validator:
<script type="text/javascript"
src="http://www.google.com/recaptcha/api/challenge?k=XXXKEY">
</script>
<noscript>
<iframe src="http://www.google.com/recaptcha/api/noscript?k=XXXKEY"
height="300" width="500" frameborder="0"></iframe><br>
<textarea name="recaptcha_challenge_field" rows="3" cols="40">
</textarea>
<input type="hidden" name="recaptcha_response_field"
value="manual_challenge">
</noscript>
<asp:customvalidator id="RecaptchaValidator" runat="server" controltovalidate="DummyInput" onservervalidate="ServerValidate" validateemptytext="true" />
<asp:textbox id="DummyInput" runat="server" cssclass="Hidden"></asp:textbox>
Note: The DummyInput is only there to make the CustomValidator happy, my ServerValidate event correctly deals with the captcha results.
The ServerValidate portion of the CustomValidator is working fine during the postback, but I need it to stop interfering with the client-side validation. If I remove the CustomValidator from the recaptcha control, everything plays nice.
Do I need to do something like call jquery-validate in the CustomValidator's clientvalidationfunction in order to make this work correctly?
Any thoughts or suggestions would be welcome.
So it turns out the answer to this issue was to set CausesValidation="False" on my linkbutton and then call Page.Validate() in the linkbutton's OnClick handler.
It's not exactly the solution I was looking for since I'll have to remember to do those things every time I want to use recaptcha (or any custom validator for that matter) but this seems to work for now.
You can set the EnableClientScript property of your validator to false:
<asp:CustomValidator id="RecaptchaValidator" runat="server"
ControlToValidate="DummyInput" OnServerValidate="ServerValidate"
ValidateEmptyText="True" EnableClientScript="False" />
i have following problem, i am using a popup jquery dialog with asp:formview .
the purpose of this popup is for user to enter a hyperlink which is placed then in textbox control in formview
the popup dialog div is located outside a formview just after body tag
<body style="background-color: #FFFFFF; font-family:Lucida Console;">
<div id="dialog-form" title="sdfdfsdf" style="font-size:14px; ">
<form>
<fieldset>
<label for="link">sdfdf</label>
<input type="text" name="sdfsdf" id="link" size="32" />
</fieldset>
</form>
</div>
<form id="form1" runat="server" style="margin-top:50px;" >
<div>
<asp:FormView ID="FormView1"
.......
<InsertItemTemplate>
...
<sometextbox ...../>
<button id="create-user" class="ui-state-default ui-corner-all">Create link</button>
...
</InsertItemTemplate>
After clicking a button a popup window is shown BUT the page starts to refresh immediately
and of course the popup is then hidden.
If I relocate the button outside the formview - the page is not refreshed, but i need it in formview..
Any idea what to do?
add the following attribute to the button:
onclick="javascript: return false;"
this behavior should not come out because it is a button not submit button.
it seems when it is inside the form view a submit action is attached to it, check your jQuery scripts maybe you mistakenly added onclick submit while attaching the dialog.
I found my answer:
clientId must be used:
FTB_API['<%=FormView1.FindControl("AdminCommentTextBox").ClientID%>'].SetHtml(...)
