I am using this javascript function to show different popups if location count varies. Here the txthiddenloccount value is null if the txtbox's visibility is false. If the visibility is true, it works fine. What strange is this?

How to make a string/Text Hidden But still working (something like visible = false but it must still work)
View 11 RepliesI'm using ASPNetDB.mdb database for membership login and another database to store ads that members submit.
In my webform that collects the ad info I'd like to populate a field with the logged in member's Name.
I inherited some JavaScript that I was told to integrate into our ASP.NET site. I thought this would be straightforward but it's turning out to be a bit of a challenge.
The code looks something like this:
<SELECT id="Question1" name="Question" onchange="updateQuestion();">
<OPTION value="notChosen">--Please Select One--</OPTION>
<OPTION value="in">India</OPTION>
<OPTION value="de">Germany</OPTION>
<OPTION value="fr">France</OPTION>
<OPTION value="us">United States</OPTION>
<OPTION value="ch">Switzerland</OPTION>
</SELECT>
The goal is to get the value from this HTML control into ASP.NET, however this control itself is being dynamically generated by another chunk of javascript, so I can't just change this to an asp.net control. My solution was to add the onchange="updateQuestion();" method, this JS will take these SELECT tags and place the values into an ASP.NET control:
function updateSecQ() {
var sQuestion = document.getElementById('<%=sQuestion.ClientID%>');
sQuestion.Value = "";
var questions = document.getElementsByName('Question');
for (question in questions) {
if (questions[question].value != null)
sQuestion.Value += questions[question].value + ",";
}
alert(sQuestion.Value);
}
As you can see, that's looking to update an ASP.NET control:
<asp:HiddenField ID="sQuestion" runat="server" value="" />
This appears to all work, however when I goto the server side on the form submit I see that sQuestion.Value is still = "".
I have a component that determines a value on a postback event.
protected void Button_Click(object s, EventArgs e)
{
HiddenField.Value = 5;
}
There's more involved in the value of course, but HiddenField is an asp:HiddenField control with runat=server set. I have in my javascript:
var id = $("#<%= HiddenField.ClientID %>").val();
The code in the javascript is set to be run only after the postback has occured (a different client click event) for the purpose of passing the hidden field value via QueryString to another URL (since i can't do a response redirect on postbacks and the client wants it in a different page anyway).
I tried adding:
ScriptManager.RegisterHiddenField(HiddenField, "Value", string.Empty);
To a !Page.IsPostback section of code, but the ID is still not set when the javascript is run.
n a page with textbox control, lets say this textbox is disabled on server side page load.What would happen if a javascript tries to set visibility of the textbox to false ?dit:Can the textbox be hidden by javascript even though it's disabled ?

The javascript generated by the asp.net SciptManager control seems to have a bug and cant handle hidden UpdatePanels. A javascript error is thrown when a control within one updated panel tries to make another update panel visible. Is this a bug with ASP.Net ajax? And does anyone have any ideas how to get around this? heres is an example of what im trying to do
<script type="text/C#" runat="server">
protected void LinkButton1_Click(object sender, EventArgs e)
{
Panel1.Visible = true;
}
</script>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click" Text="Show Panel"></asp:LinkButton>
</ContentTemplate>
</asp:UpdatePanel>
<asp:Panel ID="Panel1" runat="server" Visible="false">
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
this is the javascript error that gets thrown when clicking on the "LinkButton1" link. This error comes from the javascript that is generated by the asp.net ScriptManager control
Error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ContentPlaceHolder1_UpdatePanel2'
I've set up a page that uses JavaScript to hide or show rows in an HTML table, depending on the state of a checkbox.
So far, so good. But this is a data entry form and some rows include validation controls. However, it appears that if I hide a row (using JavaScript: style.display = 'none') that contains a validation control, the control still validates on an attempt to postback.
way I can do this but have the validation controls not do anything if that row is hidden?
I have been trying to set the value of a hidden input by using Javascript and then access the value from within my C# codebehind. When I run the code that is copied below, the value that is assigned to assignedIDs is "", which I assume is the default value for a hidden input. If I manually set the value in the html tag, then assignedIDs is set to that value.
This behavior suggests to me that the value of the input is being reset (re-rendered?) between the onClientClick and onClick events firing.

I am working on an ASP.NET application (well supposed to be deploying it about 3 days ago) and my hidden fields are loosing value when the form gets posted back..
I am using them to store information i write using javascript and on my own machine this works fine but as soon as i deploy it on our server everything else works except these values are lost..
I am using the .NET AJAX control toolkit on the same page and have noticed my calander datepicker also looses the data..
I have checked using firebug and the data is definitely getting post to the server but is getting lost somewhere!
I am calling a Java-script function, in that i am passing the value of hidden field, that hidden field i want to use at server-side, but the value of hidden field is null.
Client Side function
function getDetails()
{
document.forms[0].HdnNode.value=tree_selected_id; //HTML Hidden Field.
str="Cmp_12";
str_array=str.split("_");
var str_array1=str_array[0];
var str_array2=str_array[1];
document.getElementById("<%=HiddenNodeId.ClientId %>").value=str_array1;
document.getElementById("<%=HiddenTreeId.ClientId %>").value=str_array2;
}
Server Side Function
Public Sub InsertNodes(ByVal NodeId As String)
Dim objErrorObj As New ErrorObj
Dim ParentID As String
ParentID = HiddenNodeParent.Value
NodeId = HiddenNodeId.Value
Dim NodeIDTree As String
NodeIDTree = HiddenTreeId.Value
End Sub
have a asp.net application where I'm trying to load few documents into memory and print it. I learned that I can't use PrintDialog in a web app and the only way is to print using javascript by writing the content into a (hidden) iFrame.My question is how can Silverlight help me with this? Is it possible to show print dialog and get printer settings and print without a preview by sending the files directly to the printer? How hard it is achieve to using SL?

I'm evaluating two options of accessing a server side data on client side. Little bit confused about the efficiency or may be you can call it as finding best approach to do it.
I need to access a server side data may be an integer value in javascript on client side. I know about two options to do it.Create a public variable or property on server side and set it to javascript variable on client side as below:
var value = eval(<% =value %>);
Create a asp hidden variable and set value in this hidden variable from server side and access it through javascript using document.getElementById().
Which is the best approach and what are the pros and cons?
I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
How can i get the text of LinkButton in .NET using javascript?
Tried .innerHTMl, .innerText, .value...all not working....
in my current scenario i can't use any server controls.there is an input type button when click on this a span should come and act as water marker giving some message when you click on the message any where a run time generated text box should come in place of span.
where user can input the value and after entering if he click any where on the form the value should be assigned to new span generated run time .An example to visualize my scenario is given below i am also making a tree.
