Hi to every one...
I am developing a small ASP.NET application. It has a page where visitor can post comments, a page for the administrator to view posted comment. I display the comments on a (data) Repeater control with two checkboxes for each record to either mark posts as read or to delete the post; with both enabled property set to true.
For a test, I added a label to tell me the selected (checkbox) item. But each time I check any of the checkboxes, I don't get the expected result. This is my code-behinde file under the Page_Load event handler:
For i As Integer = 0 To rptPosts.Items.Count - 1
Dim row As RepeaterItem = rptPosts.Items(i)
Dim isRead As Boolean = CType(row.FindControl("chkRead"), CheckBox).Checked
Dim isDeleted As Boolean = CType(row.FindControl("chkDelete"), CheckBox).Checked
Dim MessageLabel As Label = CType(row.FindControl("lblMessage"), Label)
If isRead Then
MessageLabel.Text = "Read checked"
ElseIf isDeleted Then
MessageLabel.Text = "Delete checked"
End If Next
Please help me out.

Where are you binding the items to this Repeater? Is it before this code? You are most likely rebinding the Repeater and thus erasing all the changes that were made on the client-side.

Thanks for your reply.
I am binding with a DataSet under the form_load event handler.
What I want this to take effect at the click of the check box attached to the specific record.
Can I also confirm from the user before the update or deletion could take place?
Thanks.

How? You haven't shown any code. Possible like this
if(!IsPostBack)
{
Repeater.DataSource = ...
}
Previous code...

Yes, use the javascript confirm method

Seems like you have far too much code in the page load

Hi,
I am a newbie in asp.net. I am trying to connect a sql database with my web page. I have got a checkbox and a button on the page, once the check box is checked and the button is clicked the page should show the data that I want from the database table. I have written so far the following codes.
<
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
if (CheckBox1.Checked)
{
SqlConnection conn = new SqlConnection("user id = user;" +
"password = pass;" +
"Data Source = local host"); //making the connection string
conn.Open(); //opne the connection
SqlCommand cmd = new SqlCommand("SELECT (id, name) FROM customer", conn);//sql query
conn.Close();//close the connection
}
}
}
>
It doesn't work. I get the following error msg.
<
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
>
The datasouce is not right !  . I would really be appriciated if some can give an idea how can I fix it or the way I am trying to do it if it's right. Many thanks in advance.

Nothing much. Apart from checking that the window you had popped up, opened or not. You can check this through window.open("popup").closed property.
It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD

Check, if you can try with <a href with target as _blank in your scenario.

Where is your hiddenvalue field ? It is master page or in any content page?

use
window.open
rather than
window.showModalDialog to work on every browser.

What do you mean by not working ? aren't you able to open the popup using window.open() ?

Are you sure that window.open doesnt opens a new window ??
or you mean the window is not modal...
I think modal window is not standard option, so many browser will not support this feature.
