I'm trying to find a way to retrieve the value associated with a checkbox on my treeview on the check event. The OnCheckChanged event doesn't appear to work, everyone seems to be using javascript. I can get the thing to postback using javascript ... ideally I just want the value of the checkbox that was selected.

The result is a web page that allows me to navigate down to individual music files within various folders. Beside each music file is a checkbox.What I want to do is select several files and then click a button that will move the selected files from their existing location to another location. I'm running into two problems. One, whenever I add any control that performs a postback, the treeview doesn't repopulate. Two, I don't know how to retreive the values of the checked checkboxes.

I am trying to edit data using checkbox value. Firstly, I created popup window which using querystring some data from main page. In popup window, I want to change the checkbox value. For example, I made setSpare column and given the value to show bit data type such as 0 or 1 using checkbox(false or true). If some data has non setSpare(means 0), it wil lbe come out uncheckbox. If I want to check it and clicking submit button, It was not change. I am going to show the code below.
public partial class AddSpare : BasePage
{
string ObjectId;
protected void Page_Load(object sender, EventArgs e)
{
ObjectId = Request.QueryString["ObjectId"];
displayComInfo(ObjectId);
}
protected void displayComInfo(string ObjectId) // it informed relative data on web through using DB.
{
string query = "usp_ShowComputerList";
try
{
using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["SCSConnectionString2"].ConnectionString))
{
SqlCommand cmd = new SqlCommand(query, conn);
cmd.CommandType = System.Data.CommandType.StoredProcedure;
SqlParameter paramobjectId = cmd.Parameters.Add("@ObjectId", System.Data.SqlDbType.Int);
paramobjectId.Value = ObjectId;
conn.Open();
SqlDataReader dr = cmd.ExecuteReader();
if (dr.Read())
{
ModelTxt.Text = dr["Model"].ToString();
ModelTxt.ReadOnly = true;
ComputerTxt.Text = dr["ComputerName"].ToString();
ComputerTxt.ReadOnly = true;

I am using asp treeview with checkbox for the leafnode. And when that check box is checked controls are creating dynamically in aspx.cs page.
When check box is checked the entire page is getting refreshed, How can I avoid that.
Following is the code of aspx

what is the code to retrieve the id associates with each checkbox and read if whether each checkbox is checked or not in the controller action(I will need to get the status in both conditions, checked or unchecked )?
Periodically a rash of occurrences of the following error happen. I believe they're the result of hack attempts. Whether that's the case or not, my question is how can I handle the error? I want to avoid unhandled exceptions. The TreeView control is just
a standard .Net TreeView control, not a custom one. If you suggest a code solution, please code it in VB.Net as that's what I'm using.

I have a treeview which will be generated dynamically which need to be displayed on left side and when user clicks on a node it need to open a page on the right side of the same page. and each node has different aspx page. so whenever user selects a node the page details should be displayed on the right side .we can use an iframe on the page which will display the different pages clicked on the node.Is there any alternative i can use to display different pages based on the user selection on the right side without using iframe.

How bind the data through checkbox if checkbox checked is true
View 3 RepliesI am absoluetly confused. My web app has a checkbox list that my code is looking to see if the user checked it. Like I said, very simple stuff... Here's the code:
If (chkLaunch.Items(1).Selected) Then
Launch = 1
End If
The odd thing is that when it gets to this bit of code it just moves right past it like it wasn't checked. The same thing happens when I use a single checkbox (rather than a checkbox list). I've tried a bunch of different ways to make the code work but I'm left to the conclusion that I'm just not telling it to do this correctly. Either that or my project is messed up somehow.I say that my project is messed up because when I add an object to the page in Design mode, it doesn't write the source code. So when I save and close, all the modifications are mysteriously gone. This happens on multiple PC's...So, is the checkbox problem just me not doing something correctly or is my web project messed up?
While going through the checkBox I found there is written
CheckBox checkbox = (CheckBox)sender
on checkBox1_CheckedChanged event.
I have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
