Web Forms :: To Assign An Onhover/onmouseover Event To Change The Image?
Aug 7, 2010
I am currently learning dotnet (having recently learned ASP Classic) and i have come across the Menu Items and their ability to be based on the sitemap.
I love this idea and would like to use it on my demo site that i am building. However i cant seem to find a way to replace the links with images. I did have a look on google and noticed people wee using the ImageUrl method but said you have to code that yourself. I dont know how to tell it that imageUrl is ... well an image URL.
And then, should this be doable, is it possible to assign an onhover/onmouseover event to change the image?

i just made an onmouseover and onmouseout event using javascript and called the functions from the asp image tag like <contol.....onmouseover="thissss()" /> my question is why do i need to write javescrit for this? have heard so much praise of asp.net and c#! is there a way that is code to handle these events for all types of object using the .cs file (c#) directly?? i would assume the code will be under the page load event.
note:-
do not give answers assuming that the asker is a new bee consider him a completely un-educated person when it comes to coding )

I have two scripts inside my webpage
<script type="text/javascript" src="http://somesite/somefile.js"></script> <script type="text/javascript" >somecode('a','1z4j73');</script>
This script is generating a visitor map on my web page, now I don't want my user to click on the script and get redirect to that website. How can I restrict that? Can I make a div tag and make all element inside the div tag to read only? I have make sure that this restriction doesn't falls under company rules, they just want their logo under the map. Can I catch this through any event and again redirect the user to the default page? Like when user click the image, I check the URL and if the URL contains that site name I again redirect to the default page.

I have a question that is very simple to answer, I have a treeview control populated by a sitemap file, what I want to do is to assign a different image to each node/leaf of the control, let me explain a little bit more, this what I have in my sitemap file:
[Code]....
So I know that a different image can be placed for root, parent, leaf and node on the code, but I want a different image for each leaf in the treeview... I know that the easy way to do what I want is to edit/add nodes in the control BUT I populated the control from a sitemap file, so is there a way to put a different image in each leaf of a treeview control being populated from a sitemap file?

I have a textbox with autopostback=true and a button to save the data in the form. Functionality works fine when entering a value in the textbox, tabbing out of the textbox and clicking on the save button. But issue comes up when entering a value in the textbox and directly clicking on the save button without tabbing out of the text box. In the second scenario, only textchanged event fires and save click event dosen't fire. What I was expecting was after exection of textchanged event, save click event should also fire. But this is not happening.

I am successfully using the well-documented Page_Load technique to apply onmouseover behavior to ImageButtons that behave as normal links or buttons. It works like this:
ImageButton2.Attributes.Add("onmouseover",
"src='Images/CreateAccountButtonHover.gif'");
ImageButton2.Attributes.Add("onmouseout",
"src='Images/CreateAccountButton.gif'");
PROBLEM: I have a Login control with Username, Password, and an ImageButton named "LoginButton" for the Login Button. I want to apply the same onmouseover behavior to the Login Button as I do other buttons on the page. When I try to use the same programmatic syntax as above, I get this error message:
The name 'Loginbutton' does not exist in the current context
Below is the declarative code.

I've got a SQL Server database with a table in it, which lists the file names of images. It's my intention to assign the ImageUrl of an Image control on the page, from the data in the table. I've placed a SQLDataSource control on the page, and then tried putting a FormView control there, and an Image control within that. But I don't see how I can assign the value to the ImageUrl property via data binding.

I have a control that handles commenting. In this control, I have set a delegate event handler for sending an email.
I then have various types of controls, e.g. blog, articles etc, each of which may or may not have the commenting control added (which is done dynamically with me not knowing the id's), i.e. the commenting control is added outside this control. Each of these controls handles it's emailing differently(hence the event).
What I'm trying to determine, is how to assign the event in the parent control. At the moment, I'm having to recursively search through all the controls on the page until I find the comment control, and set it that way. Example below explains:
COMMENTING CONTROL
public delegate void Commenting_OnSendEmail();
public partial class Commenting : UserControl
{
public Commenting_OnSendEmail OnComment_SendEmail();
private void Page_Load(object sender, EventArgs e)
{
if(OnComment_SendEmail != null)
{
OnComment_SendEmail();
}
}
}
PARENT CONTROL
public partial class Blog : UserControl
{
private void Page_Load(object sender, EventArgs e)
{
Commenting comControl = (Commenting)this.FindControl<Commenting>(this);
if(comControl != null)
{
comCtrol.OnComment_SendEmail += new Commenting_OnSendMail(Blog_Comment_OnSendEmail);
}
}
}
EDIT:
The reason I ask is that if I search from this.Page as the initial control, I am worried about time taken to search down the control tree to find it. Each different type of page would be different in how many control it would have. On some testing, it returns back quite quickly the result.

I have icons in a gridview and when the user hovers over them the mouse pointer turns to hand and a tooltip is displayed. This works fine in IE 8. I'm testing in IE 9 and it doesn't work.
Code:
If e.Row.Cells(columnIndex).Controls(0).Visible Then
Dim iControl As System.Web.UI.WebControls.Image = e.Row.Cells(columnIndex).Controls(0)
iControl.Attributes.Add("onmouseover", "this.style.cursor='hand'")
End If
