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 have an ASPX that has a repeater. Inside the repeater is a text box with a JQuery datepicker attached to it. The text box's ID is static, so it is the same for all of those items within the repeater. However, when I make a change to the second or subsequent repeater item's date box using a datepicker, it changes the first item's date box and leaves the one actually attached to the selected datepicker alone.
Other than the obvious solution of "don't define items with the same ID," which results in another problem that will probably end up in another question, is there a way to fix this problem?
This example
<asp:Repeater runat="server"
ID="rptWhatever"
ClientIDMode="Predictable">
<ItemTemplate>
<asp:TextBox runat="server"
ID="tbxWhoCares"
CssClass="ImaDatePicker">
</asp:TextBox>
</ItemTemplate>
</asp:Repeater>
Will render the textbox to something like:
<input id="tbxWhoCares" type="text" class="ImaDatePicker"/>
So regardless of the id you should be able to do this in your script:
$(".ImaDatePicker").datepicker();
The problem with non-unique ID's is a big one but should be an easy fix if you set the attributes in the Repeater to ClientIDMode="Predictable" and leave the same attribute in the TextBox to its default.
Update
It seems jquery UI datepicker requires a unique id.
So you can select multiple inputs using a common css class but the id's must be unique otherwise you run into that problem.
It shouldn't work that way...but it does.
Alternatively you could just use the native <input type="date" ... />
$(function() {
$(".ImaDatePicker").datepicker();
});

I have a search textbox that I tried wrapping in a form element:
<form id="searchForm" method="GET" action="Search.aspx">
<input name="term" type="text" id="searchTerm" class="nav-search" size="30" />
<input type="submit" value="submit" style="display:none;"/>
</form>
I can't get it to redirect to the content page (Search.aspx) with the query string (term) from the Master Page.
I tried wrapping it in an ASP:Panel and using the DefaultButton Property but that wouldn't call the Click event in code behind.
I'm perplexed as I've searched for a solution for hours and this seems like a such common task. Thanks.
Change your code to this
<input name="term" type="text" id="searchTerm" runat="server" class="nav-search" size="30" />
<asp:Button ID="searchsubmit" OnClick="searchsubmit_Click" runat="server" Text="Search" />
in Site.Master.cs add something like this
protected void searchsubmit_Click(object sender, EventArgs e)
{
Response.Redirect("~/search.apsx?content=" + searchTerm.text);
}
This will allow to search with button click, if you want to hide it, add also panel around first code, saying that this is a button to automatically press when enter is pressed Something like this:
<asp:Panel ID="UserPanel" runat="server" DefaultButton="searchsubmit">
I have the following html:
<html>
<body>
<form runat="server">
Name: <input type="text" name="name" />
<br />
<input type="submit" name="submit" />
</form>
</body>
</html>
How do I retrieve the value in the "name" textbox posted back to the webserver to manipulate in ASP.NET WebForms?
(I know about the ASP.NET built-in controls and the possibilities with them, but I am looking for a "clean" solution without the use of built-in ASP.NET controls)
If you can't, or don't want to use asp.net textboxes, then you can retrieve the name of a regular html textbox like this:
string nameTextPosted = Request.Form["name"];
Just note that textboxes created in this manner will not automatically persist their values across postbacks like asp.net textboxes will.
Simplest solution would be to turn it into a server-side component and access it by it's name. e.g.
<asp:TextBox Id="Name" runat="server"></asp:TextBox>
...
string name = Name.Text;
Unless you have other reasons not to use a component, you'd only be making things much more difficult on your part for no justification.
ASP.net includes Html server controls for backward compatibility for just someone like you fond of html. make your html tags server controls by adding the runat="server" and id properties and you are able to access them inside your server side code with their id.
<form runat="server">
Name: <input type="text" name="name" id="name" runat="server" />
<br />
<input type="submit" name="submit" id="name1" runat="server" />
</form>
Now after this you can control their behavior:
name.Value="Hellow World !"
You have to add id and runat="server" in each control. like this :
<input type="text" name="name" id="name" runat="server" />
Its better to use asp:TextBox like this :
<asp:TextBox ID="name" runat="server"></asp:TextBox>
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 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(...)
