JavaScript To Run After OnLoad But Before Any Function To Set Defaults
Sep 7, 2010
So I have an .aspx page loading up and populating drop downs based on a lookup table in the database. What we want is for the user to be able to configure which of these values comes defaulted by specifying that value in a drop down somewhere else in the app. Now, it's easy to default the "first" value, or something like that, but we want this to act differently. Is there a JavaScript function that can run immediately after onLoad (so the drop downs are populated already), that can go through the drop down and make one of those default so it looks like the page is loading with that set as default and people don't realize the workaround? (weird masking, etc.)
Here is an example of how we add the dropdown control to the page:
With CType(.AddControl(New Controls.ComboBox("CodeId", "../../../../CodeId", "Code")), Controls.ComboBox)
.ForceSelection = True
.ValueField = "LookupID"
.DisplayField = "LookupDesc"
.Validate.AllowBlank = False
.ForceSelection = True
.ReadOnly = EditControl.IsFieldReadOnly(10580)
.BindData(Model.Codes)
End With

I'm trying to execute some javascript code on my UpdatePanel's OnLoad event like so:
<asp:UpdatePanel ID="updDropDowns" runat="server" OnLoad="javascript:ResetButtons();">
But I keep getting "'javascript' is not a member of ASP.reasons_aspx".
I tried doing
Me.updDropDowns.Attributes.Add("OnLoad", "javascript:ResetButtons();")
But I can't reference the 'Attributes' property of an UpdatePanel in the VB code-behind.

I have a windows application created using 2005. One of the screens keeps minimizing each time it's loading and I don't know why. when I look at the properties for the form, the window state is set to normal.
I did have the below line of code being used when the user clicked a button on this form because i wanted to minimize the form at that time; however, I've sinced remmed it out because of what's happening now.

I have a VB.NET function which looks like this:
<WebMethod()> _
Public Shared Function AuthenticateUser(ByVal UserInfo As String, ByVal Password As String) As Boolean
Dim UserName As String
[code]....
It calls the function, but won't return a value. When walking through the code, my VB function does fire (it will return true so long as the correct password is typed in), but the javascript 'authenticated' value remains 'undefined'. It's like you can't return values from VB functions to javascript.
I also tried
if PageMethods.AuthenticateUser("UserName", "Password")
{
//Stuff
}
But still no luck.

In my project, there are 3 user controls; BasicContact, BasicDetail and ActionTime. They are in EditOrder.aspx page. There is "ReportDate" property (Date type) in BasicContact, RadioButtonList "rdl_Priority" (with integer value from "prio_id" field) in BasicDetail and "CheckDate" property in ActionTime. The ReportDate value is derived from txt_ReportDate and txt_ReportTime and CheckDate value is derived from txt_CheckDate and txt_CheckTime.

I have a function that is responsible for populating an SSRS report. The user presses a button and I go out and check to see if there is data. If no data, I provide a NO DATA message. If there is data I call the SSRS report which I would like to open in a new window.
<script type="text/javascript">
function openWindow(url) {
document.forms[0].target = "_blank";
}
</script>

I have the following code which I want to run when the page first loads and then again when an update panel (asp.net) is run. Therefore I need to use function pageLoad() rather than document.ready.
function pageLoad() {
$(".zoomImage").each( function() {
$("<img src='"+$(this).attr("src").replace("-thumb.jpg",".jpg")+"' />").appendTo(".howitworksText > div");
});
};
Problem is I can only get this working with document.ready - so therefore not when the updatepanel is run.

I'm trying to do something which i am not sure is possible, im hoping someone will be able to prove me wrong.I have a desktop application written in VB .net which needs to post to google analytics, the interface they provide is javascript based. At the moment my application opens an internet browser, goes to a specified URL which in turn executes the javascript contained within, this is cludgey and memory gobling!
Is there any way of importing a javascript file and calling a javascript function without opening a third party browser? would preferably not want to use the browser control either.Is there a way of instantiating for instance a javascript engine and passing it the commands?

Searched a bit, couldn't find a clear answer.I have a big HTML table with numbers in it. I have a selector (radiobuttonlist) that the user can click if he wants to see the table in $ or days.Right now it works perfectly but the page refreshes because i'm calling a code-behind function (RefreshTable) everytime the user clicks on one of the two radiobutton since it changes the format and needs new calculation done by the RefreshTable function
. Is there any ways I can call that function without refreshing the page using ajax or something ?
The function has only one parameter : ProjectID, it's coded in VB.NET and we're using ASP.NET
Here's the table code from the .ASPX page, it's only the shell, everything is added thru a VB.NET method called when the RadioButton is changed (autopostback=true), so we check wich one is selected and execute the VB.NET method to populate the table. (code of the function is below)
