Why do you need an update panel for this ? If you do it entirely in local javascript, you could use firebug or similar to debug it.

As I said I was new to ASP .NET and your comments did not lead me to an answer just more questions ( I am not familiar with firebug?). I began trying this without updatepanels and I followed the suggestion to use the updatepanels to eliminate the need for significant coding to achieve the asyncronis updating. Both methods have rendered the same exact results, the image does not refresh even though the imageurl has been changed.

Here is how you might try this...
Mater page aspx
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<asp:ContentPlaceHolder ID="ContentPlaceHolder2" runat="server">
</asp:ContentPlaceHolder>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
Master page code behind
public partial class Site1 : System.Web.UI.MasterPage
{
public UpdatePanel UpdtPanel1
{
get { return this.UpdatePanel1; }
}
public UpdatePanel UpdtPanel2
{
get { return this.UpdatePanel2; }
}
protected void Page_Load(object sender, EventArgs e)
{
}
}
Content page
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
Put your map here
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="ContentPlaceHolder2" runat="server">
Image here
</asp:Content>
In code behind
protected void Page_PreRender(object sender, EventArgs e)
{
if (!IsPostBack)
{
Site1 obj = (Site1)this.Master;
AsyncPostBackTrigger trigger = new AsyncPostBackTrigger();
//Sets the control that will trigger a post-back on the UpdatePanel
trigger.ControlID = this.MapControl.id
//Sets the event name of the control
trigger.EventName = "Click";
obj.UpdtPanel1.Triggers.Add(trigger);
obj.UpdtPanel2.Triggers.Add(trigger);
}
}

this is interesting and I will give it a try, but my current Masterpage does not have the updatepanels in it, they are in the content pages. I utilize the master page for multiple pages in the website I am building. Which I believe will require a different solution. I can create a different masterpage if necessary.

Does anyone have an anwer to this problem? It seems to me that there is a timing issue involved here since the textbox updates but the image does not. Surely I am not the only person that has tried to update a imageurl in an updatepanel? This seems that this should be straight forward using updatepanels, so is there a problem with updatepanels and timing of triggers?

Th javascript someone gave you last time you asked, a matter of minutes ago, looks fine to me. how about sticking to one thread and asking further questions if you can't work out what to do with the answer you were given ?

I'm working with a Repeater control in asp.net.
I added a server control to the Repeater's Header Template.
I'm trying to get a reference to that control programmaticaly, can't figure out how to do that. Is it not possible?
Thanks.

You need to look for it inside the repeater, with FindControl, I guess.

Looks like the first control in the Controls collection is the RepeaterHeaderItem, it can be found there with FindControl.
Won't finding the the Items collection.
Thanks for the reply.

Hi~
I have a user control with a gridvew that contains a checkbox and textbox. The textbox is set to Enabled=false by default.
On Page 1: the Header of the checkbox column is "Remove" and there is a Save button. On this page I need all UNCHECKED rows to have an enabled textbox
On Page 2: the Header of the checkbox column is "Select". On this page I need all CHECKED rows to have an enabled textbox and all others to be disabled.
How do I create the javascript for these requirements? I am using asp.Net and C#.
Here is my sample code:
UserControl.ascx:
<asp:gridview xmlns:asp="#unknown">
<asp:templatefield headertext="Select">
<itemtemplate>
<asp:checkbox id="chkBox" runat="server" checked="<%#Bind(" />
</itemtemplate>
</asp:templatefield>
<asp:templatefield headertext="Size">
<itemtemplate>
<asp:textbox id="txtSize" runat="server" text="<%#Bind(" size=")%>" readonly="false" enabled="false" enabledviewstate="true"> </asp:textbox>
</itemtemplate></asp:templatefield></asp:gridview>
Current JavaScript:
function CheckChanged(cb, tb)
{
var chkBox=document.getElementById(cb);
var txtSize=document.getElemetnById(tb);
if(chkBox.checked)
{
txtSize.disabled=true;
txtSize.style.backgroundColor=\"lightgray\";
}
else
{
txtSize.disabled= false;
}
}
This javascript is getting written via a StringBuilder in the .aspx.cs file of each page. Currently, I can only get the script to work properly for Page 2. On Page 1, I need the textbox to always be enabled unless something is checked. What is the best way to enable the textboxes on this page?
Thanks!

Can you use an ajax solution to post back and enable / disable all of the controls in server side code?
Otherwise, your best bet is to create a public static string property in server side code such as textBoxIds. On the item databound event of your grid,
set
<br />
textBoxIds += (textbox)row.findcontrol("txtbox").clientId + ",";<br />
Then add javascript to iterate your comma separated string on client.
<br />
<br />
var textBoxIds = '<%= this.textBoxIds %>';<br />
<br />
<br />
var Ids = textBoxIds.split(',');<br />
for (var i = 0; i < Ids.length; i++) {<br />
var tb = document.getElementById(Ids[i]);<br />
if (tb != null) {<br />
tb.disabled = true;<br />
}<br />
}<br />
Good luck.

Would the ajax solution be better to use? I am not familiar with ajax so I am not sure how to do this.
Thanks.

Hello Experts,
In populating a DataGrid a couple options include (but not limited to):
- use of a Typed DataSet
- use of a Custom Collection of Objects
From some reading, one of the (apparent) drawbacks of a Typed DataSet is performance. One alternative is to use Custom Collections instead.
Has anyone done any benchmarking on this issue (of populating a Gridview using Typed DataSet VS Custom Collection)?

No. But I never use either. I just use a regular data table, seems easy and efficient.
I actually used to make entity classes and use generic lists. I've also messed around with LINQ to SQL and the Entity framework, but I have reverted back to simply using data tables for ease of coding / maintainability.
If you are interested in benchmarking, try using this tool. http://www.jetbrains.com/profiler/[^]
It is great and you can do your own tests to see what works best for your situation.

How can I make software lock ( or Activation Code) for web applications ?
Your prompt reply will be appreciated …
regards

Given that it needs to be hosted on a machine connected to the internet, it's actually pretty easy. But, the hard part is, I am not sure if you can package your code in a dll in the newer versions of ASP.NET. If you ship your code, people can obviously change it, although your business tier could enforce activation, then all you're giving away is your UI.

Edit. I misread the original question. I thought he asked if he could use VB.Net to communicate with a database.
