Web Forms :: Running Javascript Function Before Code Behind
Oct 15, 2010
I need to run a javascript function before my code behind runs. my element looks like :
<asp:Button ID="SuperaddsSMSPnl_Button1" runat="server" Text="Smsa" CommandName="smsa"
CommandArgument='<%#Eval("addsid") %>' CssClass="knapp" Style="left: 180px; top: 20px;" />
and in code behind I use
Dim smsbtn As Button = it1.FindControl("SuperaddsSMSPnl_Button1")
smsbtn.Attributes.Add("onclick", "showSign(this); return true;")
to show in progress sign while code behind is doing its job. but I want code behind to run by using commandName

I have the following code which should update a label to say "wait..", then run a function, and then update the label again to say it has completed:
<asp:Button ID="Button1" runat="server" Text="Upload"
onclientclick="document.getElementById('errorMessage').innerText='Wait...';"
onclick="Button1_Click" />
This works fine in IE, but not in Firefox.
When I run it in Firefox the label does not change until the process completes.
Is there a way to force the JavaScript to update the page before running the C# function?

I am trying to load the following JS method:
<script type="text/javascript">
function initialize(lon,lat) {
var myLatlng = new google.maps.LatLng(lon,lan);
var myOptions = {
zoom: 14,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map"), myOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map
});
}
</script>
In my code behind in VB.NET I then want to load such as:
initialize(53.349803617967446, -6.260257065296173)
I need to load in code behind since I have to get the longtidude and latidude from DB.

I have a javascript function named as sss() . I want to call it from the code behind.
function sss() {
$("#div-TableContent").show("slow");
alert("its Works");
};
I used this code
Private Sub dataGridView_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles dataGridView.RowEditing
If (Not ClientScript.IsStartupScriptRegistered("sss")) Then
Page.ClientScript.RegisterStartupScript(Me.GetType(), "alert", "sss();", True)
End If
End Sub
but it is not firing when the grid is in the ajax update panel. Why?

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
