I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />

There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
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 have a simple button on my form (A UserControl Form). What I would like to do is pop open a RadWindow when the button is clicked . What currently happens is a window opens and then closes, almost immediately.
I have the code below in my code behind
Private Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
BtnGenerateReport.Attributes("onclick") = " return GenerateSelectedReport('" & intPrimaryKey & "');"
End Sub
And on the client side, I have
function GenerateSelectedReport(reportid) {
var wlink = "Popuppage.aspx?intRptKey=" + reportid
window.radopen(wlink, "REPORT GENERATOR");
oWnd.center();
return true;
}

View 2 Replies<asp:HiddenField ID="mypostID" runat="server" Value=""/>
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.
i have this line of code
<%= Html.Hidden("ContentItem.ContentType.ContentTypeId", item.ContentType.ContentTypeId)%>
How do i get that value or access its data in my controller?

View 1 RepliesI'm making a GridView with like 12 fields and about 8 of them are hidden. I want to display those 8 as details of each row when I select the row with a button. I already have the jQuery function that someone in this forum gave me a couple weeks ago, it is working perfectly fine. The problem I have is that I don't get the value of the BoundField that is visible =False I just get the closest BoundField value of the index that I request (the next of the hidden one). I have used a TemplateField with a HiddenField and I have the same problem. There is some way to get those HiddenField? This is the code that I'm using:

View 5 RepliesI've been stuck on this one for a while, so it's time to consult the pros. I've created a charting application that uses javascript to do heavy DOM manipulation/generation on the client (creating barcharts made of colored divs, etc).
Long story short, I want to avoid sending my js library to the client. Is there any way to create the content on the server, using my existing javascript library, and only send the javascript-generated HTML to the client?

View 1 RepliesMaybe I've picked a totally inappropriate/bad example. What I have is a user control that contains a bunch of dynamically created Telerik RadGrids. My user control is added to a couple of Telerik RadPageViews that are part of a RadMultiPage that is used alongside a RadTabStrip. What I need to do is call a Javascript function in my usercontrol to update it's display whenever it's parent RadPageView is selected.
So basically I have the following Javascript code:
function OnClientTabSelected(sender, args)
{
// Get the MyControl that is on this tab
var myControl = $find("whatever");
// Call a method that updates the display
myControl.doSomething();
}

I recently discovered the client-side methods of some of the controls in the Microsoft ajax control toolkit. For instance, with the TabContainer, I can do something like this:
$find('tabsEditJob').get_tabs()[1].set_enabled(true);
without having to resort to server side code. Is there a way to do this in your own custom user controls without too much work?UPDATE: I was going to implement show and hide methods: although setting display to none would probably work just fine, they would prefer an explicit method. I know that the ajax control toolkit controls have a set_visible method. Do user controls get this too?
I have a webform that has a lot of controls and a submit button. When a user submits clean data, there is an asp.net label control that displays a "form submitted successfully" message. My problem is that after this successful submission, if the same user enters some invalid value for some fields on the same form and clicks on the submit button, the page still displays the success message along with the asp.net error message for that field (By using the asp.net validation control). My question is how do I get rid of the success message in this scenario? (In this case all I want to display is the client side validation error message). I am not that familiar with javascript.
<asp:Button ID="btnAddActivity" Text="Add Activity" runat="server" onclick="btnAddActivity_Click" ValidationGroup="vgSetup" OnClientClick=" return changeLabel();"/>
<asp:Label ID="lblMessage" visible="false" ForeColor="red" runat="server"></asp:Label>
function changeLabel()
{
document.getElementById('<%= lblMessage.ClientID %>').innerHTML = "";
return;
}
Here is the markup for the label and button .I tried calling a javascript function on the OnClick event .This disables the success message, but the validation error messages are displayed after a post back.I want to display the validation error messages without a post back.
I have an ASP.NET website that uses Forms authentication
<authentication mode="Forms">
<forms name="NewsCoreAuthentication" loginUrl="~/Default.aspx" defaultUrl="~/Default.aspx" protection="Validation" timeout="300" domain="someRootDomain.com" />
</authentication>
I need to identify if user is authenticated on web page after it was rendered to client. To accomplish this I thought that I can read document.cookie and check if ".ASPXAUTH" is there. But the problem is that even if I am signed in this value is empty.
How can I check that user is authenticated? Why document.cookie is empty?
