var elem = document.getElemntId('<%=control1.ClientID %>');
var elem2 = document.getElemntId('<%=control2.ClientID %>');
var elem3 = document.getElemntId('<%=control3.ClientID %>');
Can I do it in some form of concenation like:

I have a webpage in which I declared a variable in my code-behind as:
Code : Private ok As New HiddenField
I have a javascript function that sets this variable to either "T" or "F". However, I have a server-side button control that in the click() event, it checks the "ok" variable like this:
Code:
If ok.Value = "T" Then
FormatFields()
End If
The javascript function initializes the "ok" variable to "T". It goes thru a series of field edits. When a field doesn't pass the edit, it sets the "ok" variable to "F". Either way, this variable has a value. When the code-behind event above checks the "ok" variable, it's value is "".
I am calling a javascript function from .cs file which is as below:

return sb.ToString();
}
I have two integers declared at class level private int ratingLinkId = 0 ;
private int ratingValue = 0;
how I can pass these two integer values to the function "DisplayValues();" ? I have the javascript function is aspx as below:
function DisplayRatings(id, count) {

View 4 RepliesI have a nested ListView (Master/Detail) and want to invoke a JavaScript function in the detail ItemTemplate so that this function can call a static method on the server site and post the field update. I need to include three data variables in the function call, two of which must come from the ListItem data. The JavaScript call to SaveAnswer that is contained in a list item embedded in the inner listview does not render properly. The code must pass three variables: ThisPAQID is a public variable from the codebehind. I could probably make it a hidden variable on this page. QuestionID is a variable from the current listitem and is contained in the table cell immediately preceeding the SaveAnswer method call.
The nested listview works great, and if I dummy the PAQID and QuestionID values in the function call (e.g. SaveAnswer(1,1, this.Value), it works fine.
<asp:ListView ID="lstQuestions" runat="server" OnItemDataBound="lstQuestions_ItemDataBound">

I am working with Google maps api V3. I need to get the values of the getSouthWest & getNorthEast bounds of my map. To do this the 'bounds_changed' event needs to be fired in order to get the new values. This is all good, however, I need to access these values from outside the event and passed to a server side function (more specifically, I don't want to call my server side function every time the map bounds are changed).
My code is:
//Global
var sw, nw, Searchbounds;
function myFunc(){
google.maps.event.addListener(map, 'bounds_changed', function() {
Searchbounds = map.getBounds();
sw = Searchbounds.getSouthWest();
ne = Searchbounds.getNorthEast();
});
CallServerSideWebService(sw.lat(), ne.lng(), ne.lat(), ne.lng());
}
When executing this code I get the error message sw is undefined.

i'm new with design patterns and i'm not sure if in this situation i can use a composite pattern.
The scenario is a web application for an address book : the address book cointains AddressBoookItem, generalization for Contact and ContactGroup. The last one is the composite object containing a collection of AddressBoookItem.
With these scenario i'm sure that this is a composite pattern, but what is confusing me is that a contact may belong to many contactgroup. Does this request change the situation? Till now i thought that between the Leaf object and the Composite (in the composite pattern) there was a 1-to-m relationship (a composite may contains many leaf but a leaf is contained in only one composite object). Can i still use the composite pattern ? And, the last question,
How could i represent my scenario in a relational database? One table for the entire hierarchy or two table (Contact and ContactGroup) with a m:n relationship between them ?
