Javascript - OnClick/OnClientClick Event With Asp.Net?
Nov 22, 2011
I am a little confused to use this script and how it actually works?Here is my script:
<script type="text/javascript">
$(document).ready(function () {
$('#<%=TextBox1.ClientID%>').change(function () {
$('#various3').attr('href', $(this).val());
});
[Code]...
Now if I click the button it should open the iframe and display the message which I am able to do.Now the problem is how do I call the button1_Click event which is in the codebehind at the same time. I have used OnClick and OnClientClick event as shown below but it's not working and I'm not getting any errors.

I have a gridview in which I added some code for onclick in its RowdataBound event to allow the row to be clicked then go to another page.
I added a linkbutton in the last column which has the onclientclick to show a confirmation message whether to delete or not.
When I click the ok on the message, it performs my delete event. But when I click cancel, it goes to another page like what its supposed to do in the onclick.
What I am trying to do is this...
When I click the linkbutton cancel, it will perform the onclientclick to call a messagebox. If I choose cancel, I want it to not execute the onclick anymore.
I am using vb.net and asp.net in visual studio 2008. I am not sure whether this is the right forum or the asp.net.

I am working with a .Net 1.1 web application. There is a Save button that, when clicked, will pop up the Javascript confirm box. Once the user clicks OK a long running process is kicked off. We would like to show a busy indicator when the user clicks the OK button of the confirm dialog.

I've noticed there is no OnClientClick() property for the radiobuttonlist in the ASP.NET control set. Is this a purposeful omissiong on Microsoft's part? Anyway, I've tried to add OnClick to the radio button list like so:
For Each li As ListItem In rblSearch.Items
li.Attributes.Add("OnClick", "javascript:alert('jon');")
Next
But alas, it doesn't work. I've even checked the source in firebug, and there is no javascript shown in the radiobuttonlist. I'm using ASP.NET control adapters so don't know if that has anything to do with it. (I wish asp.net/javascript would just work out the box!!!)

I've written a JavaScript function which validates form input and highlights the input fields and displays any error messages, which I have tested and all works fine. i have called this function from the OnClientClick attribute of an asp:Button tag. However, if the JavaScript function determines there to be validation errors, I want to stop the form from submitting. How do I do this?

How can i load the original image when the tumbnail version of the image has been clicked? Im using ASP.NET in combinaton with javascript.
The original images are big, so they have been scaled on server side. This makes the site load faster. But somehow, both versions (original and tumbnail) of the images are being downloaded.
I'm trying to download only the tumbnail version of the image. And when the user clicks on the image, i want to show the original image.

I have read previous posts and used suggestions about firebug and selenium etc. I am still a newbie and am still pretty confused as how to implement this. I am trying to access URLs that appear when I click on a link. I have accessed the JavaScript code and the function just has a couple of parameters which I have no idea how to intercept using vb.net or C# etc.

I have a webpage I would like to parse but not too sure how to capture the links activated by clicking on links. I have take suggestions about using regex to capture the onclick statements but that does not seem to help since it does not capture anything. Here is an example of what the html contains:
<li><a href="#" onClick="SelGenre('001'); return false;">プライベート</a> (4235)</li>
<li><a href="#" onClick="SelGenre('002'); return false;">なかま</a> (1121)</li>
<li><a href="#" onClick="SelGenre('003'); return false;">ペット</a> (398)</li>
<li><a href="#" onClick="SelGenre('004'); return false;">美容と健康</a> (956)</li>
Now if I capture 'SelGenre' and try and normalize that with the webpages root etc it does not work. Clicking on the link will display other links that I need to capture.I thought it may contain some javascript file but it did not even after trying to use firebug.

I have a button that I need to use twice, the first time I click it, it validates that a string inside a textbox is a certain length. That part works.

But when I try to use a raiseevent command it gives me an error saying "the button is not an event in my program" tell me how to use the OnClick?

I have an Application with 2 forms
Form 1 = FrmWindow this is an MdiParent Form
Form 2 = FrmInput this is an MdiChild Form
On Form 1 I have a Menu that's says New Input the onclick event looks as follows.
Code:
Dim ChildForm As Form
ChildForm = My.Forms.FrmInput
ChildForm.MdiParent = Me
ChildForm.Show()
This works and opens the FrmInput as a child of FrmWindow. On the form FrmInput I have two Textbox Controls and 2 Button Controls.
Textbox 1 = TxtName
Textbox 2 = TxtEmail
Button 1 = BtnSave
Button 2 = BtnExit
On the On Click event of BtnSave I have
Code:
SaveInformation()
The Public Sub for SaveInformation Looks like this.
[Code] .....
So when you click the save button it inserts a new record into the table TblInformation on my SQL database, everything works great. Now my problem is I want to be able to open multiple instances of the form FrmInput at the same time. So I changed the New Input button to the following:
Code:
Dim ChildForm As Form
Dim ChildInstance As New FrmInput
ChildForm = ChildInstance
ChildForm.MdiParent = Me
ChildForm.Show()
This works and I can now open up mutiple instances of the form FrmInput, what I cant figure out is how to save the information on a particular instance.

I am trying to write an onclick event for textbox but VB.net does not seem to support textbox1.click(). I want to open a new form every time someone clicks on the textbox. Opening a new form is no problem, but I cant detect the click. Is there any event for textbox that detects click event? I saw something like TextboxBase that has Click but I am able to use it well.
This is how my class looks :
Partial Public Class TextBoxClick
Inherits System.Web.UI.Page
End Class
It has some basic load and init events. I am trying to write a Sub like this :
Private Sub incident_clicked(ByVal sender As Object, ByVal e As System.EventArgs) Handles Incident.OnClick
Incident.Click does not work either.
I am guessing I need to import some class to access the Click event but I am not sure which.

I have a bunch of divs on my page that are added at run time dynamically. When any of the dynamically added divs are clicked - All need to call the same function in my code behind. Each of the divs must pass it's own ID to the function. I can't use web methods as the function needs to identify which div was clicked and then show/hide/populate other controls on the page.

in my application, I pull in http code from the server side. When this code is placed into the application - the event will happen when clicked in IE, but not in any other browser. Heres the part of the code that deals with the image that is clicked and the event.
<img canExpand="true" style="cursor:hand" id="img34635" src="../images/plus.gif" EntityID="346" EntityCat="35" onclick="LoadChild(this.EntityID, this.EntityCat, 0, this.lnEquip)">
LoadChild is a javascript function on the client side of the page. When the image is clicked in anything other than IE , nothing happens. Can anyone see why this is happening? It may be a formatting issue.
edit - here is the javascript function load child
function LoadChild(lnEntityID, lnEntityCat, FullExpand, EquipID) {
document.getElementById('dropTypes').disabled = false;
document.getElementById('dropTypes').style.background = "white";

I have a question regarding VB.Net and Object-oriented programming.
I have a solution consisting of two projects.
One project is dedicated to the logic of the application, and one is only to show the Winforms form, and to reflect changes made in the logics project. In other words, when an array filled with various attributes residing in the logics project gets changed, then these changes should be reflected on the form (not that strange in theory).
Here comes the - for me - really tricky part:
I have created user controls, and these are residing in the forms project and placed on the aplication's form. When I click on any one of them, their respective onclick sub gets called okey, but how can I send a message to the logics project from their onclick subs? Basically, I'm not sure on what should be private or not, or possibly how to call the other project correctly. In any case, I can't get it to work.
To sum up: What I need is a line of code calling a class in another project, and someone telling me what should be private, static etc.

I have a button on a web page that I just need a little help with some extra code. I think I need a TRY, CATCH statement?, this is what I have so far: I have a simple web page that has a button which at the moment when pressed enables the user to add data to a DB table via a stored procedure.Once this button is pressed a pop up message box is displayed to let the user know the data has been passed. The user then needs to press the 'OK' button within this message box which then directs them to the home page of the site. This works fine.
The code for this is here:
Protected Sub btnAddRawData_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddRawData.Click
'database conn, this is linked to the web config file .AppSettings
Using dbconnection As New SqlConnection(ConfigurationManager.AppSettings("dbconnection"))
[code]....
As I don't want the user to enter duplicate records in the database (This could be done by the user navigating back to the page where the btnAddRawData_Click is located and pressing it again.), I have created a UNIQUE INDEX named 'DupRecords' to stop the user from commiting this data more than once that day.When I run the web page now I get the following message in my browser:
Cannot insert duplicate key row in object 'dbo.GasRawData' with unique index 'DupRecords'.The statement has been terminated.The solution I think, is to add a TRY, CATCH statement into the btnAddRawData_Click code.
