ASP.NET radio button is not visible in my page. I am using it inside ASP.NET ListView. I tried putting the radio button inside ASP.NET update panel content template as well. Please tell me what has gone wrong?
<asp:UpdatePanel runat="server">
<ContentTemplate>
<asp:ListView ID="FraudCheckList_listView" runat="server">
<ItemTemplate>
<p class="fraud-step-title"><%#Eval("question")%></p>
<div class="row">
<asp:RadioButton
runat="server"
class="radio-inline col"
GroupName="govt"
Text="Low Risk"
></asp:RadioButton>
<asp:RadioButton
runat="server"
GroupName='govt'
Text="Medium Risk"
></asp:RadioButton>
<asp:RadioButton
runat="server"
GroupName='govt'
Text="High Risk"
></asp:RadioButton>
</div>
</ItemTemplate>
</asp:ListView>
</ContentTemplate>
</asp:UpdatePanel>
Since you haven't shared how your code looks like, i am just assuming certain things. Just see if you have done this or not.
void Button_Click(object sender, System.EventArgs e){RadioButton.Visible=false;}
If incase its true or something your radiobutton will not be visible. In your case it must be hidden. So, make the variable of visible as **false ** So you can just change your code to this and try it out.
This you have to do it in your main code. not in your html code.
Thank You!

So, I have an event that is fired always when a text file is updated. This is the event handler:
private void FileWasChanged()
{
this.runsList.Items.Clear();
runningModels = RunsFile.ReadFile(Constants.active_runs_loc, Constants.run_file_name);
this.runsList.DataSource = runningModels;
this.runsList.DataBind();
this.updatePanel.Update();
}
Within this method I am clearing the ListView (runsList), reading the contents of the file and then binding the new data to the ListView. The updatepanel is then updated. But that does not happen, the page stays static until I press F5. Here's the layout:
<section>
<asp:ScriptManager ID="scriptManager1" runat="server" ></asp:ScriptManager>
<asp:UpdatePanel id="updatePanel" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:ListView ID="runsList" runat="server">
<LayoutTemplate>
<ul>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />
</ul>
</LayoutTemplate>
<ItemTemplate>
<li>
<asp:Label Text="<%# Container.DataItem %>" runat="server" />
</li>
</ItemTemplate>
</asp:ListView>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger controlid="runsList"/>
</Triggers>
</asp:UpdatePanel>
</section>
So I am trying to give the user of the web site real time information from the text file. For example, when I change a line in the text file, that line should be added to the web page. The event itself works fine (tested with break points and console project), but for some reason the async update does not do anything.
I tried to look for similar problems, but everyone is using a button for the asyncpostbacktrigger. However, I am very new to C# so I may be misunderstanding how UpdatePanel and ListView DataBind work.
Any help appreciated!
Cheers,

Edit: The FileWasChanged is a handler that is called from FileSystemWatcher OnChanged event. The handler updates the view if called from Page_Load or an async button trigger.
I have an ASP web form that includes divs, checkboxes, textboxes, buttons and dropdowns. Backend is c#.
I have an "Add" button at the bottom that when clicked, I want it to duplicate my form below the existing one.
Other than copying my form multiple times and toggling visibility based on a button click, is there some way I can put my form in a class and call on it based on the button click? Or any other way? Would think gridview is an option but I use divs within the form which is not allowed in gridview.
For Example:
<form id="form" runat="server">
<asp:ScriptManager ID="MainScriptManager" runat="server" />
<asp:UpdatePanel ID="updatepnl" runat="server">
<ContentTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:DropDownList ID="DropDownList1" runat="server"></asp:DropDownList>
<asp:Button ID="add" runat="server" Text="Add" />
</ContentTemplate>
</asp:UpdatePanel>
</form>
The Add button can be moved outside of the update panel if necessary. But I would like to duplicate the form below the original via clicking the Add button. Would also be handy if I could have a remove option as well.
On my aspx page I have two fieldsets, each wrapped with an <asp:Panel DefaultButton="..."> that have their own <input type="submit"> buttons. Here's an abbreviated version...
<div id="content">...</div>
<asp:Panel runat="server" id="formPanel1" DefaultButton="form1SubmitButton">
<fieldset>
<asp:TextBox runat="server" id="textbox1"/>
<asp:TextBox runat="server" id="textbox2"/>
<asp:Button runat="server" id="form1SubmitButton" OnClick="form1SubmitButton_OnClick"/>
</fieldset>
</asp:Panel>
<asp:Panel runat="server" id="formPanel2" DefaultButton="form2SubmitButton">
<fieldset>
<asp:TextBox runat="server" id="textbox3"/>
<asp:TextBox runat="server" id="textbox4"/>
<asp:Button runat="server" id="form2SubmitButton" OnClick="form2SubmitButton_OnClick"/>
</fieldset>
</asp:Panel>
Only the last submit button form2SubmitButton will postback, the other button does nothing when clicked. I have simplified the code above but I should mention that each form, Panel included, is kept in a separate user control that is registered on the aspx.
UPDATE: After some more research I've figured out that the submits are not working because of validators on the another fieldset on the master page. That fieldset is for signing into the site, so it is needed. Thoughts?
As PCasagrande mentioned, make sure your validation groups match the default button and all validators. Specially for your logging part.
Example:
<asp:Panel ID="pnlUpdateInfo" runat="server" DefaultButton="btnUpdateInfo">
<ASP:TEXTBOX id="txtZip" runat="server"></ASP:TEXTBOX>
<asp:RequiredFieldValidator id="reqvalZipSignUp" runat="server"
ControlToValidate="txtZip" ValidationGroup="btnUpdateInfo" />
<asp:Button ID="btnUpdateInfo" runat="server" ValidationGroup="btnUpdateInfo" />
</asp:Panel>
Turns out it has to do with HTML5 constraint validation. I figured this out because in chrome, from the console, I was getting the error An invalid form control with name='...' is not focusable. This led me to this post. I added the html5 attribute formnovalidate="formnovalidate" to the submit buttons and everything works just fine (*tested in chrome v20.0.1132.57, firefox v14.0.1, IE9 v9.0.8112).
So to recap, here's the answer...
<asp:Button runat="server" id="submit1" OnClick="submit1_OnClick" text="Submit" formnovalidate="formnovalidate"/>
I have an ajax extender in my aspx page.
I want to make the button do something in code behind when is pushed but my button inside the panel doesn't work.I created another button outside the panel and wrote the same thing to do and is working.
This is my button inside the panel:
<ajax:AccordionPane ID="AccordionPane1" runat="server">
<Header>Adauga titlu</Header>
<Content>
<asp:Panel ID="UserReg" runat="server" DefaultButton="but">
<cc1:Editor ID="Editor1" runat="server" width="500px"/>
<br /><br />
<asp:Button runat="server" ID="but" Text="Adauga Titlu" />
</asp:Panel>
</Content>
</ajax:AccordionPane>
This button is not working but the other button outside is working and they both do the same thing.Can you provide a solution?
Perhaps you are simply missing the OnClick attribute, like this:
<asp:Button runat="server" ID="but" Text="Adauga Titlu" OnClick="but_Click" />
Have you included the Asp ScriptManager?

My content page
<asp:updatePanel id="Panel1" runat="server" Visible="true">
<ContentTemplate>
<div>
blah blah
</div>
</ContentTemplate>
</asp:updatePanel>
<asp:updatePanel id="Panel2" runat="server" Visible="false">
<ContentTemplate>
<div>
yada yada
</div>
</ContentTemplate>
</asp:updatePanel>
Code file ..The following code is at the end of Submit button click event :-
Panel1.Visible = false;
Panel2.Visible = true;
Now earlier I was using asp:Panel..then it was working fine..like Panel 1 would hide and Panel 2 would show up instead..it was AFTER I changed asp:Panel to asp:updatePanel that things got screwed up...now the Submit button just won't work !!
What's gone wrong suddenly ?? I changed it to updatePanel so the page doesn't refresh..isn't this how we implement this thing ???
<asp:updatePanel id="Panel1" runat="server">
<ContentTemplate>
<div>
<p>
Type ur name
<asp:TextBox ID="name" runat="server">
</asp:TextBox>
</p>
<asp:Button ID="btn" OnClick="btn_Click" runat="server"
Text="Submit" />
</div>
</ContentTemplate>
</asp:updatePanel>
<asp:updatePanel id="Panel2" runat="server" Visible="false">
<ContentTemplate>
<div>
Thank You!
</div>
</ContentTemplate>
</asp:updatePanel>
At http://msdn.microsoft.com/en-us/magazine/cc163413.aspx#S3 , you can read
Multiple UpdatePanels
A page can host several UpdatePanels. By default, when one UpdatePanel on a page updates, the other UpdatePanels on the page also update. Sometimes that’s what you want, but more often than not, you don’t need every UpdatePanel updating in response to other UpdatePanels.
You can be selective about which UpdatePanel instances update (and when) by setting the UpdateMode property of each UpdatePanel control on the page to "Conditional." Then, when one UpdatePanel updates and calls a server-side event handler, call UpdatePanel.Update on the other panels you want to update. This reduces the load on the server by reducing the number of controls that render, and it reduces the volume of data in the response because UpdatePanels that don’t update don’t add anything to the response.
If you set Visible="false" on an UpdatePanel, it won't be rendered to the client at all. Therefore, if you're doing an Ajax postback, the client isn't going to be able to make the invisible UpdatePanel visible, because it just isn't there.
Think of UpdatePanels just as markers, showing which bits of your page you want to update on an Ajax postback. For your scenario, I think the easiest solution would be to use both UpdatePanels and Panels. Also, because the two things you're updating (the two Panels) are right next to each other, there's no need for two separate UpdatePanels:
<asp:updatePanel id="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Panel id="Panel1" Visible="true" runat="server">
blah blah
</asp:Panel>
<asp:Panel id="Panel2" Visible="false" runat="server">
yada yada
</asp:Panel>
</ContentTemplate>
</asp:updatePanel>
Then in the code-behind, change the Visible property on the Panel controls.
I do not know where your Submit button is, but maybe try updating those panels with:
Panel1.Update();
Panel2.Update();
