This is my code, My problem is that the onsubmit="return valform()" attribute on my form wont fire if the runat="server" attribute exists, they can't work together please help me I am clueless why these two attributes wont work together
This is because you can't use both together. As said in the docs -
<input type="text" id="Textbox1" runat="server">
Doing this will give you programmatic access to the HTML element on the server before the Web page is created and sent down to the client. The HTML element must contain an id attribute. This attribute serves as an identity for the element and enables you to program to elements by their specific IDs. In addition to this attribute, the HTML element must contain runat="server". This tells the processing server that the tag is processed on the server and is not to be considered a traditional HTML element.
Here is the reference.
http://msdn.microsoft.com/en-us/library/aa478973.aspx
under section - Using HTML Server Controls
So, HTML with run='server' will not be treated as a normal Html element and thus will always be processed by the server. If you want to override the default behavior, you have to bind your javascripts with after the html is loaded in the browser, may be using jQuery or something similar. With jQuery something like this would help -
$(function(){
$("#formreg").submit(function(){
return valform();
});
});
By examing your code, I reach on conclusion that you might be using another form tag on Master page and there is no javascript issue. Only one form tag(Server Side) can exists either on a master page or content page. They can not be nested. When you would use runat="Server" attribute on both of form tags then error occurs saying "A page can have only one server-side Form tag". So remove runat="server" attribute from one of the form tags, onsubmit would begin firing.
I solved it with very easy way.
if we have such a form
<form method="post" name="setting-form" >
<input type="text" id="UserName" name="UserName" value=""
placeholder="user name" >
<input type="password" id="Password" name="password" value="" placeholder="password" >
<div id="remember" class="checkbox">
<label>remember me</label>
<asp:CheckBox ID="RememberMe" runat="server" />
</div>
<input type="submit" value="login" id="login-btn"/>
</form>
You can now catch get that event before the form postback and stop it from postback and do all the ajax you want using this jquery.
$(document).ready(function () {
$("#login-btn").click(function (event) {
event.preventDefault();
alert("do what ever you want");
});
});

This is my aspx
<p>Date: <input type="text" id="datepicker" >
<asp:Button id="BookingForDate" runat="server" OnClick="BookingForDate_Click" Text="Search"/> </p>
<table id="DateBookingTable" runat="server" style="visibility:hidden">
<tr><th>ID</th><th>PlanTime</th></tr>
</table>
on my code in c# I can't see datepicker
why?
note please that i can take all the controllers from id except this one.
I already tried restart the visual studio
You have 2 options
add runat="server" to the input
<input type="text" id="datepicker" runat="server" />
or create an TextBox
<asp:TextBox runat="server" id="datepicker"></asp:TextBox>
You should add
runat="server"
to your input. No you are using an html control and not an asp.net server side control. Hence you can't access the value of the textbox the way you want.
So try the following and then you will be able to access the value of your textbox:
<asp:TextBox id="datepicker" runat="server"/>
Then in your code behind class you can access the value of this textbox
datepicker.Text
Another approach, as I pointed initially, it would be the following:
<input type="text" id="datepicker" runat="server">
You forgot to add the runat-attribute to your input-tag. Try this:
<input type="text" id="datepicker" runat="server">
With that change, you should be able to access the element from code behind
See MSDN
You have not given name to your control and also add runat="server"
<input type="text" id="datepicker" runat="server" name='datepicker' />
I am doing a form POST that looks like
<form action="http://ServerName/fse5/main/FormPost.aspx" id="frmLogin" method="post" target="_blank">
<table cellspacing="0" cellpadding="0" width="100%" border="0">
<%= CompleteRequest %>
<input type="submit" name="__exclude__Submit" value="Run Illustration Software Online" runat="server" />
</table>
</form>
However, when I render this HTML the input tag looks like
<input onclick="if (typeof(Page_ClientValidate) == 'function') Page_ClientValidate(''); " name="ctl00$PlaceHolderMain$IllustrationSoftwareComponent$ctl00" type="submit" value="Run Illustration Software Online" />
How come ASP.net is adding onClick and name attribute? How do I stop this?
To stop it, don't make it a user control by adding runat="server"; it seems that you don't want it/need it.
I am developing a website using asp.net c# and I want to put a form inside the page. Now as aspx pages have the form tag I do not want to nest another form inside this as it will invalidate my html. But I need this form to use GET rather than POST. I know I can change the postback url in the asp:button. Can this be done without using logic in the codbehind?
Change the method to GET just for this form not every thing on the page
change the target to _blank if possible.
Example in html of what I want.
<form action="http://maps.google.co.uk/maps" method="get">
<p><label for="saddr">Your postcode</label>
<input type="text" name="saddr" id="saddr" value="" />
<input type="submit" value="Go" />
<input type="hidden" name="daddr" value="[destination]" />
<input type="hidden" name="hl" value="en" /></p>
</form>
you can use jquery to accomplish this
$(document).ready(function() {
$("#buttonId").click(function() {
$("#formId").attr("method", "get");
});
});
the above snippet, fires when the button with id 'buttonId' is clicked. it changes the method attribute of the form with id 'formId'
You can have multiple forms in an html. ASP.NET page also supports multiple form tags, however only one of then can be server side form (runat="server").
So I will suggest that you add another form tag within your page - some thing like
...
<body>
<form runat="server">
... server controls etc
</form>
<!-- your form -->
<form action="http://maps.google.co.uk/maps" method="get">
<p><label for="saddr">Your postcode</label>
<input type="text" name="saddr" id="saddr" value="" />
<input type="submit" value="Go" />
<input type="hidden" name="daddr" value="[destination]" />
<input type="hidden" name="hl" value="en" /></p>
</form>
</body>
</html>
Note that you cannot put any server side control in your html tag. So you have to use html controls and manage them within page code using Request object.
I have a form on home.aspx that is this:
<form name="search" method="post" action="searchresults.aspx" id="searchform" runat="server">
<div class="searchField">
<input name="keywords" type="text" id="keywordSearch" value="Enter keywords" class="watermark" />
</div><!--end searchField-->
<div class="advanceSearchBox">
<p><b>Narrow results by:</b></p>
<asp:Literal ID="ltrlPopulation" runat="server" />
<asp:Literal ID="ltrlDatasource" runat="server" />
</div><!--end advanceSearchBox-->
<div style="float: right; margin-right: 2px;">
<asp:ImageButton ImageUrl="images/go_up.png" AlternateText="GO" Width="34" Height="24" id="keywordSearchGO" runat="server" />
</div>
</form>
And on my searchresults.aspx.cs page I have this QueryString but its always empty:
Response.Write(Request.QueryString["keywords"]);
Did I forget something?
You could change the opening form tag to:
<form name="search" method="get" action="searchresults.aspx" id="searchform" runat="server">
If you really want to be using query string for some reason.
That's because QueryString is for GET requests, not POST. You want to use Request.Form for posted data.
Response.Write(Request.Form["keywords"]);
Read more documentation for the Request.Form Collection here.
A post doesn't generate a query string. To access post data, you'll need to do so through the Form or Params property.
Request.Form["keywords"];
Request.Params["keywords"];
You're posting to searchresults.aspx, so you will need to access your posted variables through Request.Form or Request.Params.
string keyWords = Request.Form["keywords"];
OR
string keyWords = Request.Params["keywords"];
how can i add text to a legend from code behind
Assuming you're talking about the HTML Legend Tag and using C# in an ASP.NET site. You can give it an ID and a runat="server" then you can access it from the code behind by name and change its text property.
<form id="form1" runat="server">
<fieldset>
<legend id="myLegend" runat="server">Personalia:</legend>
Name: <input type="text" size="30" /><br />
Email: <input type="text" size="30" /><br />
Date of birth: <input type="text" size="10" />
</fieldset>
</form>
Then in the code behind:
myLegend.InnerText = "Foo";
