View 4 Replies I am using google map APIs in my ASP.Net application and using following line to pass LatLong to
java script function- GmlMoveEditorMarkerAddress (declared in .ascx file).
[code]....
Above code is running on button_click/dropdown_selectedindexchange but not on page_load.
In the first Page_Load, I am activating a javascript function to make an ImageButton change between 2 images with an interval.
This works fine.
Now when pressing this imagebutton, the Page_Load event will fire the second time and all this is happening in an updatepanel which means a partial postback.
The question is how to execute the javascript function stopbk() in the Page_Load event in this scenario as I cant just put it in the "Onload". How can I make that work?
Code is below:

I am using a Timer with a 3 minutes interval. I am exeuting the Page_Load event every 3 minutes. I am doing that this way as I have all this code inside an UpdatePanel1 which causes
a partial unnoticed postback to the server. I have a lot of code in the Page_Load event that I havenīt put here.
But what does not work is the code I have in the Page_Load event now.
I am trying to execute the javascript function with this line: body1.Attributes.Add("Onload", "startbk()");
This function should start an imageButton to change image between 2 images. This function do works if I refresh the page so the function itself do works.
But it seems this function does not execute when the Timer executes the Page_Load event, so this is my problem how I can solve this?

I'm not getting any errors, but the above is not calling the function. How do I call the javascript function?
how to execute the code behind function using JavaScript keypress ?
The reason is that the keypress that I'm referring to will be used in searching record so I want that every keypress a result will be shown in the gridview immediately.
Basically, I have a gridview that is opened in a new window from the parent window. It has a bunch of records with a view button to view the details of each record (which stays in the same newly opened window). I have a calendar in the parent window that accepts a Date querystring parameter to set the current date on the calendar at page load. I'm just trying to refresh the calendar in the parent window to match the date of the label in the newly opened window. All the code below is in the newly opened window. The .Net code-behind below refers to when that view button is clicked and everything is populated. At the end, I call the js to refresh the parent window and pass the value of the LabelScheduleDate as the querystring parameter. Now the label comes through as '03/25/2010' in the code-behind, but when I pass it to the js, it comes through as '0.00005970149253731343' in the end querystring. I'm not really sure what is making the value change, and I want to pass it as just text. Do I need to pass it as a string object? I tried but I don't think I was doing it right.
JavaScript Function
function RefreshParent(inputDate) {
window.opener.location = window.opener.location + "?Date=" + inputDate;
}
.NET Code-Behind
Protected Sub RadGridOnlineRequests_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGridOnlineRequests.ItemCommand
If e.CommandName = "ViewOnlineRequest" Then
' populates LabelScheduleDate among other controls values
ScriptManager.RegisterStartupScript( _
Me, Me.GetType(), "clientScript", "RefreshParent(" & LabelScheduleDate.Text & ");", True)
End If
End Sub

I have a java script function which presents a countdown timer.when the timer reaches zero, I want to somehow activate a function on the server side in the code-behind.I understand it is impossible to directly call a server-side function, but is there a simple way to still fire it?I want to fire the (event-handler) code behind function: protected void ButtonFinish_Click(object sender, EventArgs e).
var _countDowncontainer = 0;
var _currentSeconds = 0;
function ActivateCountDown(strContainerID, initialValue) { _countDowncontainer = document.getElementById(strContainerID);

View 8 RepliesMy motto is to call a Java script function at the end of button click code behind. ie, firstly i need to execute the server side function after which my java script function should get invoked. My server side method is as follows
protected string SaveEmbedURL_click()
{
if (txtembedurl.Text != null)
{
School aschool = new School();
aschool.SchoolId = CurrentSchool.SchoolId;
aschool.EmbedUrl = txtembedurl.Text;
SchoolRespository.updateEmbedUrl(aschool);
return "true";
}
}
My Java script function is as follows
function SaveEmbedUrlClientSide() {
admin_CustomizeTheme.SaveEmbedURL_click(true);
$('#lbl_embedcode').removeClass('hide').addClass('show');
$('#embedCode').removeClass('hide').addClass('show');
CopyToClipboard("embedCode");
}
