Here is what I need to do: I need to execute some server side code after a user clicks on a button, THEN I need to execute some client side code. OnClientClick gets invoked BEFORE the onClick; and what I need is the opposite.
Is there a way to do this? It looks like I will have to execute JS code from the server code.
I have buttion on web page and client side java script ConfirmResetPassword() for confirmation message which return true or false
[Code]....
if (confirm("Are you sure you want to reset password of this user?")) {
return true;
}
return false;
}
}with Telerik AjaxSetting[Code]....
<input type="button" name="ctl00$ContentPlaceHolder1$btnResetPassword" value="Reset Password" onclick="javascript:return ConfirmResetPassword();__doPostBack('ctl00$ContentPlaceHolder1$btnResetPassword','')" id="ctl00_ContentPlaceHolder1_btnResetPassword"
/> ?
I am using following server side code to save the data from ASP.NET Control toolkit Editor to the database It follows with the HTML Code The problem is that, data is saved successfully. But it is saved twice. Main problem is this server side event is fired twice. How can i prevent it from firing twice?
Server side code

Here is my code
<div id="AuthenticateUser" runat="server" style="display:block" >
//login control
<asp:button id="ValidateUser" ... />
</div>
<div id="ForceToChangePassword" runat="server" style="display:none" >
//reset password control
</div>
On click of "ValidateUser" button, I do check whether user is valid or not. Based on some condition I do need hide "AuthenticateUser" div tag and show "ForceToChangePassword" div tag. I really like the jQuery fadeIn/fadeOut effect. I can easily do that on client side. But how can I give that effect after executing server side code?
I tried to call javascript method from code behind that method has a fadeIn/fadeOut logic but it seems like that javaScript method is never been called.
Was trying to reference this the other day, and I've heard them called several things.They are intrinsically hard to google for. Does this syntax have a proper name?
View 6 RepliesI have a user control with a dozen radion buttons in it.Every pair of radio buttons execute a Sub on server side.All of the radio buttons have the autopostback set to true.There is a public Sub of the usercontrol that gets called only once by the page and loads the data setting the radio buttons to checked or not checked.The problem is, that once a radio button is set, it will execute it's server side code on every postback even if the postback is caused by another control on the usercontrol or even another control on the page. So if all the radiobutton pairs are set and a postback is caused, there will be six server side Sub executing! Casting the sender in each of those Subs gives back the radiobutton that is checked at that point, so it's if on every postback the event is fired for each checked radiobutton.
View 2 RepliesI have an asp.net button, that when clicked calls a code behind function. The function does some evaluation, and then I want to call javascript from within this asp.net function.
View 2 RepliesI just finished building a new version of a web app that imports custom-formatted documents. However, now I just found out that I need this web app to also import custom documents from 3 years ago. I have the code from 3 years ago that imports the older docs...

I'm using the following code in an attempt to show a dialog with a list of errors on the client:
if (rollout.ImportErrors.Count > 0)
{
ClientScript.RegisterClientScriptBlock(GetType(), "showErrors", "showErrors();", true);
}
The error count is non-zero and the following script block is emitted, but the script isn't executing.
<script type="text/javascript">
//<![CDATA[
$("#error-report").dialog("open")//]]>
</script>
If I call the function directly from a Firebug console window, the dialog shows properly, so I know the dialog and my code are working. BTW, this code is in a content page, using a content placeholder that 'injects' code into the element of the rendered page.
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");
I have a asp.net panel that is initially hidden and is shown when a button is clicked. There is javascript inside that panel and it doesn't execute after the panel is set to be visible. I can see that javascript function gets outputted on page but it is not called. What can I do to make it so that function gets called? Here is an example:
<asp:LinkButton id="lbtn" runat="server" Text="show" OnClick="lbtn_Click" />
<asp:UpdatePanel id="upnl" runat="server" UpdateMode="Conditional">
<contenttemplate>
<asp:panel id="pnlContent" runat="server" visible="false">
content initially hidden.
<script>
alert('done!');
</script>
</asp:panel>
</contenttemplate>
<triggers>
<asp:AsyncPostBackTrigger ControlID="lbtn"/>
</triggers>
</asp:UpdatePanel>

View 3 RepliesI wrote a code to call some event...
[Code]....
and
[Code]....
js calls this code and I get object reference not set to an instance of an object
[Code]....
I then decided to run the whole thing on the server it uses the same code above but I now have several parameters to pass in and call a slightly different stored procedure
DataSet dsEx = new DataSet();
SqlCommand testcommand = new SqlCommand();
testcommand.CommandText = "spLockUnlock";
testcommand.CommandType = CommandType.StoredProcedure;
testcommand.Connection = sqlLockUnConn;
testcommand.Connection.Open();
testcommand.Parameters.Add("@OffState", SqlDbType.Varchar);
testcommand.Parameters["@OffState"].Value = ViewState["OffState"].ToString();
testcommand.Parameters.Add("User",SqlDbType.Int);
testcommand.Parameters["@User"].Value = lblUserID.Text;
testcommand.ExecuteNonQuery();
testcommand.Connection.Close();
rest of the code follows
The stored procedure uses the parameters to lock certain records, then I use exec spOfflineSystem which executes a series of select statements (as above), then I unlock the records afterwards....no problems however my dialog box on the front now reads
CustomersEC45TG.xml
If you step through the code the filename reads Customers.xml yet on the front end we get the spurious characters....each time this is executed the spurious characters are different. Only every now and then will the correct filename dialog box show.
I was looking the Highlight effect of Jquery's. That effect is really the one i would like to add in my webpage.
By looking at the the source code, i noticed that the effect will be reproduced on user's click of the div.
$("div").click(function () {
$(this).effect("highlight", {}, 3000);
});
In my webpage i have an ImageButton
<asp:ImageButton ID="btnFavorite" runat="server" ImageUrl="~/Images/Favorite.png"/>
I would love to perform the highlight effect to the div, when the user clicks on the image button. Is it possible?
UPDATE: If it is possible, could i use something like "OnClientClick=" of the ImageButton, since the imagebutton controls are added dynamically to the webpage?
I have a web application where I want to stop any malicious JS to execute.
For example:

If a client does the above then an alert box pops up on the client screen. How to stop that.?
Also I have set validateRequest="true" in the machine.config but still the JS does get execute.
I am calling a simple console application (exe) using process.start. Within this application, I am writing events to the event log.

I have a Global.Asax and Global.Asax.cs file that is specific to my particular Asp.net project. For some unknown reason the code in my Global.asax.cs file is not being executed. I thought that the breakpoints were being ignored, however that is not the case. Because if I try to deliberately force an error to occur, the code is never executed. Below is an example of what I am talking about. The real code in my Application_Start method is not shown below. ANd other methods are not shown as well.
I have tried renaming the Global.asax file and then re-creating it, and that did not work either. Strange because when I try and create a new Global.asax file, the option to create a code behind file is greyed out.
Why isn't my Global.Asax.cs code being executed?
private void Application_Start(object sender, EventArgs e)
{
int x = 1;
int y = 1;
int z=1/(x-y)
}
I can't find the namespace where it's stored - in the view code I can execute Html.TextBox(<name>, <contents>, <html attribs>) and Html.DropDownList(<name>, <select list contents>, <html attribs>) but how do I execute these methods in controller code?
In case you are wondering why on earth I want to do this, rather than using the TextBox object, I execute Html.TextBox(....).ToString() and create html code from these objects.
