InitComponents();
var type="";
type=document.getElementById(dlAdmissionType.id).value;
document.getElementById(hdnAdmissionType.id).value=document.getElementById(dlAdmissionType.id).value;

I'm having some trouble with making use of some AJAX-properties that are normally accessable after I've initialized a scriptmanager.
ie. This work:

Now, I would like to call the javascript-function 'testFunc()' from my ASP.NET Codebehind-file, and here's my problem. I keep getting "Sys is unidentified".codebehind-stuff: ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "testkey", "testFunc();", true);
Does anyone have good idea how to solve this?
Much appreciated. Thanks.
I have a aspx page that, when loading, will initialize a class called, Bill :)
When Bill is initialized, the aspx page will wire a function to a handler of Bills.
When that function in Bill is fired, I would like to call a javascript function in the aspx page, but that is where I am having difficulties...
I have tried ClientScript.Register and all of that, but nothing is seeming to work. As of now, I am simple trying to get the function to fire an alert.
How would you call a Javascript Function from CodeBehind on Page Load event without : Ajax (ScriptManager), Response.Write ?
View 2 RepliesI have the function put here like below:
$(document).ready(function () {
UserControlNameInit();
});
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript">
</script>
However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...
OK, this feels like a question that should be easy to answer, but as with so much mixing of asp.net and jQuery, it's a bit of a nightmare.
What I want to do is be fading a div in and out at various times during the client's viewing of my asp.net page; I fade it out using jQuery's fadeTo() before triggering an UpdatePanel update (to indicate that the data there is not fresh) and I want to fade it in again once the UpdatePanel has been updated. I've gotten as far as updating the UpdatePanel in the codebehind, and this results in the div's content changing... but how do I fade the div back in again?
The way I see it, there are 2 ways; register an event handler on page load to detect when the div's content has been changed and fade it back in, or call a function from the asp.net codebehind when I've updated the div to fade it back in.
In the first case, there doesn't seem to be any event triggered by the div's content changing, so I can't seem to do that. If anyone knows how I could get a client event to trigger when I update the div, that would be a nice solution.
In the second case, I thought that this was what ClientScriptManager was for, but it doesn't quite do what I want. I want to be able to register a particular Javascript function with ClientScriptManager and then tell ClientScriptManager to execute it in the client, from my codebehind. You can't seem to do that. ClientScriptManager.RegisterClientScriptBlock() simply inserts some <script> into the HTML output, rather than calling a function. Presumably this would work if I kept registering things like:
<script>fadeBackIn();</script>
because the Javascript would be immediately evaluated and run, but this feels messy, and that feeling is intensified by the fact that I'd have to keep randomly generating a new unique value for the key argument of ClientScriptManager.RegisterClientScriptBlock(), because it's specifically designed to stop this kind of repeated code. However, I'm struggling to see an alternative.
I'd really like something along the lines of:
ClientScriptManager.RegisterClientScriptFunction("fadeBackIn", "function fadeBackIn(){ ... }");
ClientScriptManager.ExecuteClientScriptFunction("fadeBackIn");
<asp:LinkButton CssClass="button" ID="btnApply" runat="server" OnClick="btnApply_Click()" OnClientClick="Apply1('btnApply')" >
hi ihave this functin in .vb file
Protected Sub btnApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnApply.Click
end sub
and javascript function also in aspx
function ApplySummerization(id)
{
alert("hai");
}
I added some javascript to fill in a dropdown and it works wonderfully. However, when I try to access the value in codebehind to submit the data, the value shows as null. (string strValue = ddlName.SelectedValue;).

I am writing an ASP.Net application. I am making use of master page in it. I have several child pages with me, which consist of some java script functions; Let's say;

And master page java script function as;
function MasterPagefunction()
{
//Need to call ChildPagefunction(); here
}
Now is it possible to call ChildPageFunction() from MasterPageFunction()?
