Send AJAX request to server and check new records are inserted. Use JS, setTimeout method and check for new data frequently. If you are using ASP.NET AJAX extensions, you can use the Timer control provided which make things easy.

I have two treeviews in my form, which contains checkboxes for leaf nodes to select. The objective is to transport the selected nodes to second one. I am able to do that, but the issue is I'm not getting in a tree structure, just listing one by one. Can anybody please help?
Following is my code:
protected void AddUnit_Click(object sender, EventArgs e)
{
AddParentNode();
for (int i = 0; i <= AvailableUnitsTreeView.Nodes.Count - 1; i++)
{
AddUnits(AvailableUnitsTreeView.Nodes[i]);
}
}
private void AddParentNode()
{
if (SelectedUnitsTreeView.Nodes.Count== 0)
{
TreeNode Parentnode = new TreeNode();
Parentnode.Text = AvailableUnitsTreeView.Nodes[0].Text;
Parentnode.Value = AvailableUnitsTreeView.Nodes[0].Value;
SelectedUnitsTreeView.Nodes.Add(Parentnode);
SelectedUnitsTreeView.Nodes[0].ShowCheckBox = false;
}
private void AddUnits(TreeNode node)
{
for (int i = 0; i <= node.ChildNodes.Count-1; i++)
{
AddUnits(node.ChildNodes[i]);
if (node.ChildNodes[i].Checked == true)
{
SelectedUnitsTreeView.Nodes.Add(node);
SelectedUnitsTreeView.Nodes.Add(node.ChildNodes[i]);
}
}
}
Cana anybody pls help how to achieve the tree structure in the second treeview also?
It's urgent. pls

I foundout the solution. Thought that it might be useful for somebody. Just add two more lines as follows in AddUnits function:
TreeNode MainNode = new TreeNode();
MainNode.Text = node.Text;
MainNode.Value = node.Value;
MainNode.ChildNodes.Add(node.ChildNodes[i]);

Hi, I have an application that uses the .net AJAX toolkit. The dll's are included in my project.
Im looking at a web hosting packages(not dedicated). If they say they support .net 3.5 does that automatically mean that they support AJAX?
Thanks

To be clear with the hosting plans, you may need to check out the server support team directly.

No. You can contact the support and confirm that server supports ASP.NET AJAX extensions. I use http://www.bizhostnet.com/[^] and they have support for it.

Hi,
I have this two lines of code
Response.Write("alert('Successfully Assigned.');");
Response.Redirect("SomeOtherPage.aspx");
but it is always going to the redirected page without displaying the alert
Any solution??
Thanks

|
|

Can we have the Response.Redirect statement replaced by a self.location.href within the script itself?
I believe, the 302 Redirect is taking precedence in your case.

When I used HttpContext.Current.Session["ConnStr"] it s through NullReference error.
What should I do??????

vnsraj wrote: When I used HttpContext.Current.Session["ConnStr"] it s through NullReference error.
Because the session variable is not initialize. where did you stored the variable in Session ? Why you are not checking the Session variable is null or not before access ?

I create session["SessionValue"] in aspx page and assign this to class file
public static String DBConnectionString
{
get
{
if (HttpContext.Current.Session["ConnStr"] != null)
{
return HttpContext.Current.Session["ConnStr"].ToString();
}
else
{
return "";
}
}
set
{
HttpContext.Current.Session["ConnStr"] = value;
}
}
But when I go to other pages then its show null exception but I check session is null or not.
like below
if (HttpContext.Current.Session["ConnStr"] != null)
What should I do

So, you are doing this stuff in a Separate Class file? Did you Implement IHttpHandler, IReadOnlySessionState
