Hi sir,
I have created dynamic imagebuttons. In that postbackurl was not working. So i wrote addhandler. I want to open selected image in new window. How to call the selected image id or get the imageurl in img_Click event..?
Dim tRow5 As New HtmlTableRow()
tblParticulars.Rows.Add(tRow5)
tCell = New HtmlTableCell()
tCell.Align = "Left"
tCell.Width = 300
Dim Img As New ImageButton
Img.ID = "AdvImg" & cnt
Txt1 = Ds1.Tables(0).Rows(i).Item("AdvImg")
Img.ImageUrl = "~/Photos/" & Txt1
Img.Height = "70"
Img.Width = "60"
AddHandler Img.Click, AddressOf Me.Img_Click
tCell.Controls.Add(Img)
tRow5.Cells.Add(tCell)
Private Sub img_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs)
End Sub

you have to give events like :(in C#)
Img.Click += new EventHandler(Imgbtn_Click);
This will fire the event:
protected void Imgbtn_Click(object sender, EventArgs e)
{
//your code here
}

//write the below code in any one of the events.I prefer RowEditing.
string link = ((TextBox)GridView.Rows[e.NewEditIndex].FindControl("htmllink ")).Text;

In my application I am using query string.But i have faced some problem.when i am passing values which has special characters like (&) or (') it encounters a problem.
it only takes the value before special characters.For eg:if i pass value "Finance&Account" then it only give the value"Finance" at the other page.Is there any way to handle it.
Thanks in advance.

You need to encode the &, otherwise it means a new variable. There's URL encode methods inside .NET.

you have to use encode and decode functionality:
//encode
string aa = "Finance&Account";
string url = string.Format("Default1.aspx?name={0}", Server.UrlEncode(aa));
Response.Redirect(url);
//decode
name = Server.UrlDecode(Request.QueryString["name"]);

Hello Friends,
I've a DataList in this DataList i've a Div onclick this <b>Div</b> a popup window opens. And also this div holds some Labels to display the data and a Button onclick this button a Image Url is displayed.
But the problem is as i click on this Button, Image Url is displayed but a popup window is also opened. But i want if i click on Button only ImageUrl is to be displayed otherwise popup window should be opened

Hi,
Since your button is inside the Div.So, whenever you click on button then Onclick function of Div will also be fired.
Please post your code so that alternate solution can be find

Thanks for your reply; but it will only fire onclick function; it will not execute the next part of the code which has been written in the Sub..End Sub.

Your core issue is that you are clueless. No, you cannot make a page cycle pause half way through to run some JS, then continue. Not possible. Anyone who thinks it might be, has no idea about ASP.NET.
You can do a postback, or you can use AJAX. You need a seperate call between the code that runs before the alert, and the code that runs after.

If you're doing homework, you should talk to your teacher. If you're teaching yourself, start with something more basic. If you are doing paid work, then you are a disgrace, you should tell your client that you're robbing them. If someone hired you, they are a disgrace, also.
I told you want to do. You need to change your overall design, because you cannot prompt the user in the middle of a postback. If you're not asking them a question, if you just show a message, you can probably show it in the middle of what you're doing. If you're redirecting to a new page, that page needs to show the message.

I am disgrace, i am robbing my client. Thanks for putting "personal attack" replies in the general forum by such an expert person.
Its really shocking how easy they write; who gave them such rights, rather than helping the students/novice developers. I have'nt read anywhere till now, that ignorance is a crime or helping the people means you have full right to "show" the bossism.

If you have a client, then yes, you are. You don't know enough about how ASP.NET works to write reliable, production quality code. As I said, I'd hope you were a student, or just someone teaching yourself, and in those situations, I gave you advice. Taking jobs that you're not capable of, is indeed stealing.
Girish481 wrote: rather than helping the students/novice developers.
I am here to help novices, in fact, I gave you your answer. However, would you like to have a 'novice' doctor or electrician ? One who has no idea what they are doing, and asks people on the internet as they do the job to make sure they get something that kind of works at the end ? I doubt that. There's a level of novice that is able to write production code, and there's a level that is not at that stage yet. Based on what you're asking, you don't really understand ASP.NET at all, so that puts you in the latter category. And, I still answered you.
Girish481 wrote: that ignorance is a crime
Pretending NOT to be ignorant, and taking money from people based on skills you do not have, is criminal.
Girish481 wrote: or helping the people means you have full right to "show" the bossism.
And yet, you have a paying client, not the remotest idea how to do the job, and so you're here, asking us to do your job for you. So long as you want free help, you need to take everything that comes with it.
And, I don't mind helping people who are writing code for work. The issue is that there's a minimum level of competence and knowledge which is required before it's reasonable to charge for your work.
