In my page, I am usign a treeview. For some purpose i need to enabled and disable the treenodes. While disabling the treenode, I use the following code to change the text:
treenode.ChildNodes[i].Text = "<font color = Gray>" + treenode.ChildNodes[i].Text + "</font>";
while enableing, I put Black instead of Gray.
However, while viewing the page, it was Gray always. When I debugged, it is assigning both the color as follows:
treenode.ChildNodes[i].Text = "<font color = Black><font color = Gray>" + treenode.ChildNodes[i].Text + "</font></font>";
How to remove the grey colour while assigning the black color? Please help.
Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

I think there is no option for this in the Treeview Control. You need to extend the Treeview control and then override the RenderPreText to apply color.

Hi all i need a small help regarding gridview.
I will show some information on loading a page. When ever a user clicks on Edit or delete it should redirect to a login page. Only the login user can edit or delete the data. How can i do this.
|
|
|
|
|
By checking whether user is logged in or not on edit & delete click. 
|
|
|
|
|
Can i have the sample code
|
|
|
|
|
Sure, but first tell me, what are you doing for Login functionality?
|
|
|
|
|
Just a basic login like this
protected void Button1_Click(object sender, EventArgs e)
{
SqlConnection Con = new SqlConnection(ConfigurationManager.AppSettings["sqlcon"]);
SqlCommand cmd = new SqlCommand();
cmd.Connection = Con;
string sql;
sql = "Select *from login where uname='" + TextBox1.Text + "' and pwd='" + TextBox2.Text + "'";
cmd.CommandText = sql;
Con.Open();
SqlDataReader dr = cmd.ExecuteReader();
if (dr.Read())
{
Response.Redirect("Default.aspx");
}
}

This is not a proper Login.
You need to use either Session Variables or FormsAuthentication Class.
For more details, please use Google.

}
}
private bool validate(String Uname, String Pwd)
{
bool val = false;
SqlConnection con = new SqlConnection(ConfigurationSettings.AppSettings["sqlcon"].ToString());
string qry = "Select Uname, Pwd FROM login";
SqlCommand cmd = new SqlCommand(qry, con);
SqlDataReader dr;
con.Open();
dr = cmd.ExecuteReader();
while (dr.Read())
{
if ((Uname == dr["Uname"].ToString()) & (Pwd == dr["Pwd"].ToString()))
{
val = true;
}
dr.Close();
return val;
}
return val;
}
protected void Login1_Authenticate(object sender, EventArgs e)
{
if (validate(Login1.UserName,Login1.Password))
{
Login1.Visible = false;
Label1.Text = "Success";
}
else
{
Label1.Text = "Failed";
}
}
}
Is this code efficient for login

Hi all,
I have checkboxes in datagrid to select and a delete button outside the datagrid to delete the checked row in datagrid. After checking the check box and clicking the delete button, in the btndelete_Click im finding the check box in the datagrid and deleting the particular record, but im getting the checked false in the btndelete_Click of the datagrid checkbox which is checked. Please tell me why it is so and how can i find the checkbox of datagrid is checked or not in button click. The code is below:
protected void btnDelete_Click(object sender, EventArgs e)
{
foreach (DataGridItem DemoGridItem in grid.Items)
{
CheckBox oCheckbox = (CheckBox)DemoGridItem.Cells[1].FindControl("chkDelete");
HiddenField hidImageName = (HiddenField)DemoGridItem.Cells[1].FindControl("hdnItem");
if (oCheckbox.Checked == true)
{
try
{
Delete code;
}
catch( Exception e)
{
}
}
}
}
Thanks in advance for ur help.

The real question is, where do the checkboxes come from ? Best guess, your page load is binding to the datasource and erasing any selected items.

I have created menu from scripting using

|
|

if You are using forms authentication use this
if (Page.User.Identity.IsAuthenticated)
{
}
or if You are using session check the session
If this is not your answer Sorry..!
Then be More clear..!

thnks for ur reply bro...............but i think u r not getting my question..........i hav created menu in html using UL tag,LI tag, and ANCHOR tag with scripting...............in this condition how to check .......

I have 2 questions for this.
1)Why would you go for html tags rather than using Navigation control in asp.net.
2)How You are checking for particular user whether he is logged in or not..!

Then You are redirecting to particular page .Check the login condition.
But IMO Its not good.
But If you are using forms authentication . forms authentication will take care of it..!
Thts the advantage of forms authentication.

If your security system works at all, then a pure link is fine because your page itself will check if the user is logged in. On the other hand, a good design would not show options that the user is not allowed to access. Giving people the URLs to your pages that they can't access, is a good first step to their trying to break in.

Well, your basic idea is kind of bizarre. Why would you need this ? Your control will keep it's value after pageload, unless you change it.

Hi all,
I am using ASP in that i want to know how to hide the query string part in the address bar.
For example,
I have defined a hyperlink as
<a href="http://mywebsite.com/sumpage.asp?action=xyz"></a>
so, in browser i want to show only
http://mywebsite.com/sumpage.asp and hide the rest of the part.
How can i do it ??
Thanks in advance..

You can't. You can perhaps encrypt it, but there is no way to hide it.
