I've got a basic web form page which I use 2 user controls on. The first control has the second nested within it...
On my first popup.ascx i have the following javascript validation
[Code]....
txtDate works fine so is there some issue with having nested user controls and using getElementById I'm missing?
i am using the multiview control inside a page and i am trying to find a control using the javascript function document.getElementById. My Problem is that the function returns null cause it cannot find the control. When i open the code of the page from the browser the active view is not rendered so I think thats the reason why I am getting a null value from the function.
On the HTML code is rendered only the first view or the view that is activated on page load.
Is there any way to find a control inside the view using javascript? or I am doing something wrong?
I'm trying to get the Google map API to work with ASP.NET. I got it working on an HTML page but it does not work on a ASP.NET master page/content page. The problem seems to be getElementById not finding a div assigned to an ID.
View 3 RepliesI thought I heard we would be able to get the value of an asp:textbox by id with javascript in the .net 4 framework? was I mistaken? if not does anyone know the syntax?
View 1 RepliesI am simply trying to store a label in a variable in javascript but for some reason this isn't working with document.getElementById('control');. I know my javascript is linking to my html file fine because everything else works.
Here is my javascript code:
function performEvapCooledCircuit(txt)
{
var error = document.getElementById('lblError');
if (txt.value == null || isNaN(txt.value))

I have a usercontrol that hides a div when a button is clicked.
<asp:LinkButton ID="lnkbtn" OnClientClick="ShowHide(); return false;" runat="server" />
<div id="popupPage" style="display:none;">
</div>
function ShowHideGotoPopUp() {
var ob = document.getElementById("popupPage");
if (ob.style.display == "none")
ob.style.display = "block";
else ob.style.display = "none"
}
There is a problem when I place on page more then 1 usercontrol, all controls has div with same id = popupPage.
I've got a .aspx page which loads a user control using the LoadControl(string virtualPath) method. The loaded control contains references to several other user controls (i will call "modules"). If such a module contains an unhandled coding error which isn't catched at compile time (e.g. division by zero), no helpful error is thrown. The .aspx page just gets an error from the LoadControl method that the control to load cannot be found (404), but in fact it contains a faulty module.
Is it possible to get the error of the module from within the .aspx page for better troubleshooting? Can I get information about, that (in this example) there is a division by zero error in module (nested user control) xy?
I have created a gridview (this is a usercontrol) with another gridview (also a usercontrol) inside it. Now I would like to bind a checkboxlist to the inner gridview. This is my markup for the inner gridview user control
<asp:GridView AutoGenerateColumns="False" GridLines ="None" Width ="100%"
Is there a better, cleaner way to do this in ASP.NET 2.0?
An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.
The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.
The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.
I have a form that contains a number of user controls (partial views, as in System.Web.Mvc.ViewUserControl), each with their own view models, and some of those user controls have nested user controls within them. I intended to reuse these user controls so I built up the form using a hierarchy in this way and pass the form a parent view model that contains all the user controls' view models within it.For example:
Parent Page (with form and ParentViewModel)
-->ChildControl1 (uses ViewModel1 which is passed from ParentViewModel.ViewModel1 property)
-->ChildControl2 (uses ViewModel2 which is passed from ParentViewModel.ViewModel2 property)
-->ChildControl3 (uses ViewModel3 which is passed from ViewModel2.ViewModel3 property)
My question is how do I retrieve the view data when the form is submitted? It seems the view data cannot bind to the ParentViewModel:public string Save(ParentViewModel viewData)...
as viewData.ViewModel1 and viewData.ViewModel2 are always null. Is there a way I can perform a custom binding?
Ultimately I need the form to be able to cope with a dynamic number of user controls and perform an asynchronous submission without postback. I'll cross those bridges when I come to them but I mention it now so any answer won't preclude this functionality.
I am using a masterpage. On a accounts page I have a Usercontrol on this UserControl I have one more user control. If Account is closed I want to Disable all the controls on Accounts page ( including parent and child userControl - controls collection).
View 1 RepliesI've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page
and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?
I'm trying to create a nested gridview, but I'm stuck at the editing/deleting part of the nested gridview. (Below is my code).The nested gridviews are filling out nice, I've set the DeleteParameter in the SQLDataSource, but I'm still getting this error when trying to delete a criteria: 'The Gridview 'gvCriteria' fired event RowDeleting which wasn't handled.'I've tried to create a method 'gvCriteria_RowDeleting', but that didn't seem to work out.Someone who can give me a piece of advice? Would it be possible to fill the gridview without using gvDomain_rowDataBound? Dries

I have a webpage with a select object and a GridView object. For testing my problem i've created asp button and html button.On pageLoad the GV is empty and select is being filled with names. (GV is not appearing)After choosing a name from the select options, the user should click a button and then the GV need to be filled with relevant info.I am having 2 "related" problems:
1. When clicking on the asp button and getting into the click function on the aspx.cs file, i can't find the select object and retrieve the selected option. How can i get this?
2. When clicking on the html button and getting into the button_click function on the aspx file (javascript), i can't find the GV object (getElementByID("GridView1") returns null). I guess that it's because the GV is not loaded initialy since it's empty.I've tried also using callback methods, but the although it seems like i am reaching the GV and performing DataBind(), the GV table won't show on the page.
In the below code, "Hello" displayed inside <p> element is getting invisible within a second after clicking button.
So how to display it permanently?

Objective:
Have the MultiView1 display only if Frieght values exceed 15.50. If check box is checked, retreive the row values of the Gridview1 and Gridview2 to perform a task.There will be two check boxes. One will be conditionally hidden. Each check box has a different function.

I think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.
View 2 RepliesI hava a page default.aspx having master page abc.aspx and web user control login.ascx i want to call perform simple alert function on login button but not on client click event. For e.g
Protected Sub BtnMyIpLogin_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnMyIpLig.Click
'Some Validation part here for user login
'then my if condition like
If flag_alert = 0 Then Page.ClientScript.RegisterStartupScript(Me.GetType(), "btnflag", "alert('Your Download / View Limit Exceed More Than 90%');", True) End If
but it is not working.........................
I have a label "lbl1" that I am trying to locate in a content page from the Master page. I want to do it dynamically so I am trying to pass the name of the control (which in this case is lbl1) through as a parameter. I don't get an error, it just doesn't work. If I do an alert to see what the string "temp" looks like, it is correct, but iit seems as if Javascript ignores it. I believe it has something to do with the '<%= not being interpreted correctly by the browser I'm sure it is a simple solution, but I can't figure it out!

I have a page with some datasources in it. I am doing reenginering of the page itself and would like to split some parts of the page in several user controls. In my code I have an ObjectDataSource object with the following params
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
TypeName="DataSetTableAdapters.PhotosTableAdapter"
SelectMethod="GetPhotosForAlbum">
<SelectParameters>
<asp:ControlParameter Name="albumID" ControlID="txtAlbumID" Type="Int32"/>
</SelectParameters>
</asp:ObjectDataSource>
This piece of code automatically bind the hidden field "txtAlbumId" to the datasource. In my revision this datasource should be moved to a user control. What is the best way to handle a scenario like this?

I just like to know how to pass a parameter to the datasource of my dllItemCodeFooter and dllItemCodeEdit Drowndownlist which calls my getItemCodeList(decimal categoryID) method in the code behind. The value of the parameter will be seletectedValue of the first dropdownlist ddlCategoryFooter or ddlCategoryEdit).I know it could be done in code behind, but i prefer to bind my datasource in asp page. I want to achieve something like this DataSource='<%# getItemCodeList(ddlCategoryEdit.Seletected)%>'

It seems liken no matter what logic I put in my code, this runs every single time, and because of this, unless I am viewing this particular content page, I get an error.
View 13 RepliesMy website has a "charts" menu item that lets you choose from about a dozen pages each with a different chart in them. Each one of these pages uses the same nested master page which has some drop-down lists and text boxes to let the visitor do some filtering of what data shows up in the charts (I do this by building SQL statement parts in the nested master page and triggering an event that the chart page reacts to).
Anyway, One of the DropDownList controls shows the names of everyone in the Company (I use MembershipProvider and RoleProvider). What I want to is have the DropDownList show a different collection depending on the role that the visitor is in; If the visitor is in the "Principal" role, I want them to see everyone. If they are not in that role, I want them to get only their own name.
I expect I'd have to do this in code-behind... But thought I'd check to see if anyone knows if it is possible to have an "IF" statement in the SQL DataSource for this control that can refer to the role that the current logged-in user belongs to
On page load is there a way to enumerate all the nest user controls for that specific page load?
I'd like to be able to enumerate all the user controls that implement an interface, and call the interface method for the controls before asp.net passes control to thier page_load events.
The problem is from the master page level, any page in the app could be loading, and each of them could have any random user control, and I need the type reference to determine if they implement the interface, and to call the method.
