how can i call a VB function - deleteevent() in usercontrol.ascx.vb from a javascript function in clickhandler(e) in usercontrol.ascx. The call should cause a postback because I need the usercontrol to display the changes.I am currently trying to do it by using a linkbutton with style display:none, and calling its click event from the javascript function. But i dunno how to call the click event.

I am developing an Outlook 2007 VSTO application that works with a commercial website.Almost all of the app's interactions with the website are done using HttpRequest objects.One user scenario does require the app to open a browser to a specific page on the site, and that page requires a Post string to provide the results of a form submit.I am using the version of the WebBrowser control that ships with VS 2008, and specifically VB.Net.My code successfully goes to the first page, after which it navigates to the actual target page (once the first page is loaded).That works, too, but if I click on the desired link on the target page, a JavaScript error pops up, stating "'j.parentNode' is not an object", with a Code of 0.I do not have access t the commerical site's internals. The page and links in question, when accessed via IE or Firefox, work correctly without the JavaScript error. The page containing the link is using Flex.Is this a problem with the nWebBrowser control?

View 3 RepliesI have an .aspx page. In this grid I'm adding a bunch of controls. The first control however is an ExtObject, not one of our preset VB.NET controls. When I go to access the value on the backend for this field with this code:
form.AndOr.getValue()
It doesn't work. Basically, the radio button value isn't saving when I save the rest of the stuff. So I tried to add code to do it. It was just defaulted to 'And' each time. Below is a snippet of code from the actual asp.net grid.
With .Item(2)
.Ref = "../Payee2"
.LabelWidth = 90
With .AddFieldSet("Payee 2")
.AddControl(New Forms.Control("", "../PayeeId")).Hidden = True
.AddControl(New Forms.Control("", "../AddressId")).Hidden = True
[Code] .....
And I get this error:
form.AndOr is not defined
Does the Ext ref: mean something different than my controls and how I access them?
I'm having some issues finding examples of how to use the Awesomium web browser control in vb.net with objectforscripting. I know that objectforscripting isn't the same for the webcontrol used with awesomium since its HTML5 and not the traditional IE control that comes with vs 2010. The issue I'm having is finding any info/examples on how to communicate with the awesomium web browser control with my javascript. It's quite easy with the IE built in control with objectforscripting. I've found samples of how to do it in C# but I don't see any info of how I could do it just in VB. I've searched several things in google and I just can't seem to find anything on how to do it.So for example, I would have a button in a php page that the webcontrol browsers to and if I click the button it closes the application down. So I need to communicate using window.external with the webcontrol in VB.

I know how to InvokeScript so my VB form can call a javascript function in the Webbrowser document, but does anyoe know how to do it the other way round - ie javascript calling a vb function in the containing form? Why do I want to do this? Well I've got a table of telephone conversations. Some conversations are longer than others and they look silly in a grid with fixed row height. So I put them in an html document and display them in the webbrowser control. There's a hyperlink on each subject title, and I'd like the hyperlink to open an 'edit conversation' dialog box in my app.

Hello: i have javascript code for a popup calendar and works fine if a form is a form control:
<form id="FormView1" runat="server">
however, if i use my formview control w/ the same code for a formview control, it doesn't put the value back into my text box txtDate after the user selects the date:
<asp:FormView ID="FormView1" runat="server">
<asp:TextBox ID="txtDate" runat="server" TabIndex="3" Width="65px" ></asp:TextBox>
<a onmouseover="window.status ='Please Select Date';return true;"
onmouseout="window.status='';return true;"
href="javascript:show_calendar('FormView1.txtDate');">
<img alt="open calendar" src="images/SmallCalendar.gif"/></a>
this seems to be the only difference so i was wondering if perhaps i need to reference this form in a different way? i don't know why it won't work for my formview control.
Basically what needs to happen is when the user clicks edit onto the gridview and clicks on a certain textbox a javascript calendar popups up and the user picks a date.So far, I can set it statically and the calendar works for that one row, but not the other rows since the ID changes.My ASP Code (id of textbox has been set to txtStartDate):
<asp:TemplateField SortExpression="StartDate" HeaderText="Start Date">
<EditItemTemplate>
<asp:TextBox ID="txtStartDate" onClick="ddlchange()" Runat="server" Text='<%#Bind("StartDate")%>'>
[code]....
This works, for one textbox. It does not work for other since 'ct102' changes with every row.
I use a Repeater that's databound to a DataRowCollection and programatically build a table through that. I have something similar to:
Private Sub SubAcctGrid_OnItemDataBound(ByVal sender As Object, ByVal e As RepeaterItemEventArgs)
If e.Item.ItemType = ListItemType.AlternatingItem Or e.Item.ItemType = ListItemType.Item Then
Dim currentrow = TryCast(e.Item.DataItem, DataRow)
Dim acctSummaryTable = New Table With {.ID = "acctSummary" & e.Item.ItemIndex, .CssClass = "minisub_acct_table"}
[Code] .....
I can't pass in the correct element ID, though. From what I understand, ASP.NET transforms the ID I assign into some huge long ID for the sake of uniqueness. For example, I assign a table with the ID 'drillDownTable0' and it spits out 'ctl00_drillDownTable0' in the HTML markup. It worked the first time around, but then the Repeater gets binded to a new row and then I get 'ctl01_drillDownTable0' so on and so forth. I've tried the ClientID, ID, and UniqueID where I add the attributes to the Cells in the code above and they don't do what I need to. Is there any way I can get that ID and pass it to the Javascript function? Or I guess a better question is: When are the IDs generated and can I get to them before the page is rendered in HTML?

View 4 RepliesI am using a Webbrowser control to access the elements in an HTML page which contains a JavaScript link which when clicked, adds extra content to the page.

I have used this successfully with a submit-type link to login to the web site, but cannot get it to work with the JavaScript link.

My VB.NET code is supposed to execute third party Javascript code in an attempt to fill in and submit a form. This process consists of five steps, and I have been able to submit the form when all the steps are kept separate (i.e. behind 5 separate consecutive button clicks). Now, what I'd like to have is one button to handle all the five steps.
The problem is that the form originally only appears after calling "webbrowser.Navigate" command, which apparently modifies the page's HTML code. I seem to be unable to detect when Javascript has finished loading the new HTML in order to fill and submit the form. I have tried a timer control to wait for a certain HTML element ID to appear, but in vain. [URL]
I am attempting to create a ASP .Net (VB.Net) custom control for an auto-complete drop down that uses jQuery auto-complete.The basic flow is the consumer of the control will set some properties (such as the data source) which will then be injected as javascript to initialize the autocomplete.There are a lot of pieces involved so i may have missed posting some of the code, please comment if you think something is missing and i will add it.the consumer's code behind (PreInit event):
myDropDown.DataCallback = "testFunc";
the DataCallback property in the control:
Public Property DataCallback As String
the options object creation and javascript injection in the control code behind (PreRender event):
Dim _serializer As New JavaScriptSerializer()
Dim optionsObject As New Dictionary(Of String, Object)
optionsObject.Add("source", DataCallback)
[code]....
when i debug into the initialize function, i see options has one property, source, with the string "testFunc" as it's value. what i need is for source's value to be testFunc (not as a string) so it can be executed as a callback in autocomplete instead of autocomplete thinking it is a URL.
