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.

padmanabhan N18-Jun-09 20:19

18-Jun-09 20:19

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"]);

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.

Girish48118-Jun-09 19:50

18-Jun-09 19:50

I am cluless, do'nt know asp.net programming; but what will you do; if such case/issue come to you where you have to code/solve the problem; how can i send the alert message to the user.

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.
