}
</script>
<asp:TextBox id="MyTxtBox" runat="server" Visible="false" />
How do I execute an JavaScript function right when an ASP.NET text box control is populated and focus is still set? The onChange event will not work because I need to programmatically move focus to the next form element after the JavaScript function has executed.
Is is very similar to this question. The marked answer is correct for the context on the question, but after some more testing it did not exactly solve my current issue.

All i want to do is call a function lets say "ShowOverlay()" from my code behind using ClientRegisterScript() and it should do the same as it is doing on button.
I have a page with some custom validation which displays a result in a validation summary. I would like to reposition this validation summary to the bottum of the page without causing the page to scroll with the length of the validation summary. I have a jQuery function which does this very nicely, however, I need to execute this jQuery after the validation summary is displayed and i'm not sure which event to trigger.
$(document).ready(function(){
$("#<%= vsmSummary.ClientID %>").change(function(){
var newTop = $(window).height() - $("#vsmSummary").height();
var newLeft = ($(window).width() - $("#vsmSummary").width()) / 2;
$("#vsmSummary").css(
{
'position': 'absolute',
'left': newLeft,
'top': newTop
}
);
});
});
In my custom validation method I build this string and register with the RadScriptManager...
Dim scriptText As String = "$(document).ready(function(){ " + _
"$(""#<%= vsmSummary.ClientID %>"").ready(function(){" + _
"var newTop = $(window).height() - $(""#vsmSummary"").height();" + _
"var newLeft = ($(window).width() - $(""#vsmSummary"").width()) / 2;" + _
"$(""#vsmSummary"").css(" + _
"{" + _
"'position': 'absolute'," + _
"'left': newLeft," + _
"'top': newTop" + _
"}" + _
");" + _
"});" + _
"});"
RadScriptManager.RegisterClientScriptBlock(Me.upSCPPage, Me.upSCPPage.GetType(), "DynamicVSM", scriptText, True) This works!! I had no clue that I could call this from my code behind!! I will be doing this much more in the future!
How can I launch a function on the server(in a controller) from javascript?

I need to execute a javascript function when a row of a datagrid is clicked. I am not sure how to do this.
I have tried adding a template column with a button
<asp:TemplateColumn>
<ItemTemplate>
<asp:Button
ID="myButton"
Text="Insert
collection"
OnClientClick="putData();"

And then attaching the javascript to it:
myButton.Attributes.Add("onclick",
"putData()")
But it produces an error.
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?

How can I trigger a jQuery function with the Gridview Select button? I want that the select button trigger the jquery function that has the row details (it's already working with a asp:buttonfield ), and select the row so i can get the values and send it trough e-mail with another button. I don't know if this is possible. or, Can I trigger the jQuery function from code behind with the select button Sub? How?

var _countDowncontainer = 0;
var _currentSeconds = 0;
function ActivateCountDown(strContainerID, initialValue) { _countDowncontainer = document.getElementById(strContainerID);
