I have searched the internet and can't find out what my final problem is. What I have is a RadGrid that I am adding a bound sub-column to a parent bound column. Now, the relation field's bound column appearing but even though I am binding a List<> to it I get the message: No child records to display. Below is the code so if anyone can help with my final problem that would be great!

Hi,
RadGrid provider is having forum for supporting their product ( in your case it is RadGrid). Their forum would be best place for any of your query related RadGrid control. Please find the below link of Telerik forum which supports grid related query.

Thanks,

You question is not clear. Are you looking for some image zoomer? if yes then you can use jquery one. have a look for example

hi iam using asp.net with c#
i have the images displayed in the page
when any image is click then the image size should be big
in the same page
can you give me example which helps me

developerit wrote: when any image is click then the image size should be big

You need to write a javascript method to show the image in a overlayed div tag. You can use that javascript either on Mousehover on image or click - depends on your choice!

Google for it, quite common thing.

hi, iam using this code
protected void Button1_Click(object sender, EventArgs e)
{
string fn=FileUpload1.PostedFile.FileName;
string[]fi=fn.Split('\\');
string name=fi[fi.Length-1];
FileUpload1.PostedFile.SaveAs(Server.MapPath("images\\"+name));
ImageButton1.ImageUrl = "..images" + fn.ToString();
}
but image is not displaying in image button at run time
can you correct the code where iam going wrong
|

developerit wrote: ImageButton1.ImageUrl = "..images" + fn.ToString();
Image path needs to be corrected. "..images" is wrong (also you asre missing a forward slash after images folder!). Either a forwardslash or a tilda(for root directory) needs to be there. You have to check what path it has to be to fix it.
Probably it should be:
ImageButton1.ImageUrl = "~/images/" + fn.ToString();
ImageButton1.ImageUrl = "../images/" + fn.ToString();

Dear All,
I have very simple statements which popsup a menu
as bellow
<script language="javascript" type="text/javascript">
var ie5=document.all && !window.opera
var ns6=document.getElementById
if (ie5||ns6)
document.write('<div id="popitmenu"></div>')
function showmenu(e, which, optWidth)
{
menuobj=ie5? document.all.popitmenu : document.getElementById("popitmenu")
menuobj.innerHTML=which
menuobj.style.visibility="visible";
return false
}
function hidemenu()
{
var div = document.getElementById('popitmenu');
if (div)
div.style.visibility="hidden";
}
if (ie5||ns6)
document.onclick=hidemenu;
</script>
<body style="width:100%; height:100%">
<form id="form1" runat="server">
<div>
<a id="a" onclick="return showmenu(event,linkset[1], '180px');">Click here</a>
</div>
</form>
</body>
every time i click on "Click here" which displays popupmenu it suddenly hides, I debugged the statements and I got that every time the function hidemenu() is executed. as I am assigning hidemenu function to body click event which means, If i click at body the popupmenu should hide, but the question is here, If i am clicking at "Click here" why the hidemenu is called, or how I can hide the popupmenu.
simply, when I click at click here the popup should appear but when i am clicking at other places the popup should hide, how to achive it in above?

Because, Click here is a part of the page body (its in it!)

On body click, call a javascript method where you can check if the click was on 'Click Here' div tag, if so, dont do anything or else hide it.

Here is a simple example which i believe
accomplishes what you want ...
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<script>
linkset = new Array("hiyas","sup");
showmenu = function(thiss){
pop = document.getElementById("popmenu");
pop.innerHTML = "px = "+ thiss.px + " link = " + linkset[thiss.link]
pop.style.visibility = 'visible';
}
hide = function(e){
if(e){
id = e.target.id}
else{
id = event.srcElement.id}
if(id !="show"){
document.getElementById("popmenu").style.visibility = 'hidden';}
}
document.onclick=hide;
</script></head>
<body>
<form id="form1" runat="server">
<div>
<a id="show" onclick="this.px='180px';this.link='1';showmenu(this)" >
Click here
</a><br>
<a id="show" onclick="this.px='90px';this.link='0';showmenu(this)" >
Click here
</a>
<div id="popmenu">Hello Im a menu</div>
</div>
</form>
</body>
</html>

Hi,
I am creating a TCP Chat application using Asynchronous method calls and I have created 2 applications, one of which is a mobile app that runs on a PDA and the other on a desktop pc.
At the moment i can send text back and forth but i would like to send emoticons too. I am using a richtextbox, how could i go about doing this?
I would appreciate your thoughts and advice.
Thanks,

How about using some textual representation of the emoticon? Suppose you have a  , you could encode this image as :-D, and a  encoded as :-@. Replace the string with the images before display, and replace the images with their respective codes when you want to send/save the message.
Would be somewhat similar to coding your own "escape characters".

I find the repetition of sets of controls for each of the EditItemTemplate, InsertItemTemplate, and ItemTemplate templates of a FormView to be tedious and risky, in terms duplicating layout and code etc. I would much rather create a xxxDetails user control, and use this in each template, cutting layout and code location down to one location.
However, this introduces several complexities for data binding scenarios. Are there any extablished patterns or practice guides for using user controls in these scenarios?

If it is so then:
Clean the solution, rebuild it... if using IIS, then reset it.
Clear browser cache... run the application after all this...
