var HiddenField1 = a;////////////////////////C# code where give me value of a
HiddenField1.Value = a.ToString();
My hidden field and Function to access the hidden field value
<asp:HiddenField ID="HiddenField1" runat="server" value="" />
Method to access the hidden field value in Jquery code.
var HiddenFieldcheck= $('#HiddenField1').val();
alert($('[id*=HiddenFieldcheck]').val());
but every time it give a empty value how I solve it ...
I have a usercontrol on the content page. I'm trying to access this usercontrol's hiddenfield.
I was able to access it before applying the master Page. But once I changed the page to a content page , the value in the hiddenfield is showing empty.
alert(document.getElementById('<%=hidLat.clientID%>').value) is showing the value.
I have a property PickupHidLat defined on the ascx page and I'm using this property to access hidLat value on the content page.
objBLL.Latitude= DirectCast(uc_MyClient.PickupHidLat, HiddenField).value
why is the value null on the content page?
<asp:TemplateField>
<ItemTemplate>
<asp:HiddenField ID="HiddenFieldTime" runat="server" Value='<%# Bind("Time") %>' Visible="False" />
</ItemTemplate>
</asp:TemplateField>
When I load the page, it shows up as a blank cell. Is there anyway to hide it completely as it looks out place?
Im trying to figure out what the value is from a specific hiddenfield value when selecting a specific row in a datalist.....
I tried to find an example on the net....but today I seem to find all the wrong codes...
I have a repeater which always has 1 UserControl, however the UserControl can vary, lets say it could be UC1, UC2 or UC3.
When I come to validate that a hiddenfield in each is not empty, I iterate through the repeater items but I have to do a findcontrol on UC1 check an exposed value, then do the same for UC2 then UC3. In all its a bit unwieldly.
What it would be great to do is iterate through the repeater items find the hiddenfield (which is the same name for each UC) and test that in one go, like below:
foreach(RepeaterItem item in Repeater1)
{
... some code here to start off with
HiddenField hfAnswer = (HiddenField)item.FindControl("HF_Answer");
if(hfAnswer != string.Empty)
do something here
}
i am using JQuery UI Autocomplete with asp.net textbox.AutoComplete works right.but how can i assign selected ID of returned Data to an hiddenField?My server Side Function returned list of objects that contains (this is an example) :
public List<Employee> GetEmployeeList()
{
List<Employee> empList = new List<Employee>();
empList.Add(new Employee() { ID = 1, Email = "Mary@somemail.com" });
empList.Add(new Employee() { ID = 2, Email = "John@somemail.com" });
empList.Add(new Employee() { ID = 3, Email = "Amber@somemail.com" });
empList.Add(new Employee() { ID = 4, Email = "Kathy@somemail.com" });
empList.Add(new Employee() { ID = 5, Email = "Lena@somemail.com" });
empList.Add(new Employee() { ID = 6, Email = "Susanne@somemail.com" });
empList.Add(new Employee() { ID = 7, Email = "Johnjim@somemail.com" });
empList.Add(new Employee() { ID = 8, Email = "Jonay@somemail.com" });
empList.Add(new Employee() { ID = 9, Email = "Robert@somemail.com" });
empList.Add(new Employee() { ID = 10, Email = "Krishna@somemail.com" });
return empList;
}
and this is ASPX Code :
<form id="form1" runat="server">
<div class="demo">
<div class="ui-widget">
<label for="tbAuto">
Enter Email:
</label>
<asp:TextBox ID="tbAuto" class="tb" runat="server">
</asp:TextBox>
</div>
</div>
<asp:TextBox ID="TextBox1" runat="server">
</asp:TextBox>
<asp:Label runat="server" ID="lbl" Text=""></asp:Label>
<asp:HiddenField runat="server" ID="hidid" />
<asp:Button ID="Button1" runat="server" Text="Button" />
</form>
here is my jquery Code :
<script type="text/javascript">
$(function () {
$(".tb").autocomplete({
select: function( event, ui ) {
// now assign the id of the selected element into your hidden field
$("#<%= hidid.ClientID %>").val( ui.item.ID );
},
source: function (request, response) {
$.ajax({
url: "Default.aspx/FetchEmailList",
data: "{ 'mail': '" + request.term + "' }",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
dataFilter: function (data) { return data; },
success: function (data) {
response($.map(data.d, function (item) {
return {
value: item.Email
}
}
)
)
}
,
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
alert(errorThrown);
}
});
},
minLength: 1
});
});
</script>
And this is My WEb Method Side Code :
<WebMethod()> _
Public Shared Function FetchEmailList(ByVal mail As String) As List(Of Employee)
Dim emp = New Employee()
Dim fetchEmail = emp.GetEmployeeList()
Return fetchEmail
End Function

I need to send some parameters to an external website using the <asp:HiddenField /> controls and also at the same time, submit data to a sql server database. The part for submitting the data to the database is working, but I need to try to get the parameters from the hiddenfields to also be passed through. I thought all I had to do is create the hidden fields and in the code behind, set the values from the textboxes that the user would fill out.
My source code is below:

What am I missing? The hidden fields are losing their value before posting to the external website. I've looked everywhere to see why this won't work.
This is my code.iam providing alternate coloring for my columns in dynamic table.In this i want to avoid Alternate row style color for hiddenfield.

I have a for which is built within an ASP.net usercontrol. This form is then used within a CMS as part of integration with a merchant gateway. The gateway requires that a number of hiddenfields be passed in which is fine in the main however one of these needs to be called Profile. The CMS I am using also defines a global variable called Profile and as such when I try and add a hidden field with this ID I get errors.
Is there a way of setting the 'name' property to Profile, and the ID to something different?

I wanted to ask if I could do something like:
<asp:HiddenField ID="mypostID" runat="server" Value="<% Response.Write(Session["ïd"])%>"/>
I cannot access the session from the user control code behind but if I put a Respose.Write on the page itself it shows the session value.

Looks like the "asp:HiddenField" doesn't have an "AutoPostBack" property, and I'm having problems with the "OnValueChanged" event... I need to call a function (C#) when I populate the hidden field, but in my case nothing happens. And I cannot use any scripts.
