|
|
1 - Handle the first dropdowns selected index change event.
2 - Query database to get the cities for the selected country
3 - Bind the results to second dropdown.

I am certain that MSDN has examples of this. Does google not work where you live ? Don't you have any ASP.NET books, most also cover this.

What part of that error message is unclear?

Thanks for ur reply...
If you are aware of the solution please let me know.....
|
|

|

There is no solution. Change your design. Why ASP.NET application requires registry access? Usually hosting providers will not give access to registry. If you have a dedicated server, you can impersonate the user before accessing registry. But it is nasty.
|
|
|
|
|
Sorry the issue is im not accessing any registry..and moreover i did"nt write any code inside cs file ...and i guess by default ASPNET application may require access to registry....

Looks like your are using some session settings in web.config, and that is trying to access machine key for encrypting session data (Although not sure).

In windows 2003 server in IIs 6.0 when i tried to change the process account of the application pool to Local System through script(because i should not change manually and that(changing process account) should happen when installing MSI itself) it worked fine ie in IIS 6.0 but im strugling how should i change process acount to Local system in IIS 5.0 thru script....
Any way changing process account to Local System is not safe but i cannot
manually go to registry and add the ASPNET account and give read and write access....
And in IIS 5.0 ie in Windows Xp pro if i set Permissions for
HKLM\SYSTEM\CurrentControlSet\Control\Lsa Select this key and add ASPNET machine account with read and write permissions then im able to clear error Where LSA(local Security Authority)...
But as i said i should not do manually....

Hi all I want to create a very generic search control which i can use it on any page.so as to search the data from the table provided by user,list of columns and the sql will be dynamically created depending on textbox id and there respective values.
Please Suggest how do i create a server control so that i can use it on any page which will be either return dynamic sql or datasource for binding with gridview.
protected void Button1_Click(object sender, EventArgs e)
{
string conn=server=localhost;database=MyData;uid=sa;password=password";
SqlConnection sconn = new SqlConnection();
sconn.ConnectionString = conn;
ArrayList ar = new ArrayList();
ArrayList ar1 = new ArrayList();
foreach (Control c in Panel1.Controls)
{
Type t = c.GetType();
string id;
string value;
string name = t.Name;
TextBox t1 = null;
if (name.Equals("TextBox"))
{
id = c.ClientID;
ar.Add(id);
t1 = (TextBox)c;
if (t1.Text.Length>0)
{
value = t1.Text;
}
else
{
value = "%";
}
ar1.Add(value);
}
}
bool lbHasWhere = false;
StringBuilder loBuffer = new StringBuilder();
loBuffer.Append("Select '"+columns+"' From '" + tablename+ "'");
for (int k = 0; k < ar.Count; k++)
{
if (lbHasWhere)
loBuffer.Append(" And ");
else
{
loBuffer.Append(" Where ");
lbHasWhere = true;
}
loBuffer.Append("" + ar[k] + " like '" + ar1[k] + "'");
}
SqlCommand scomm = new SqlCommand();
scomm.CommandText = loBuffer.ToString();
scomm.Connection = sconn;
sconn.Open();
SqlDataReader sdr = scomm.ExecuteReader();
GridView1.DataSource = sdr;
GridView1.DataBind();
sconn.Close();
}
}

Hi,
I have an click once application. The prerequisites which i have mentioned is .net Framework 2.0. If the prerequisite is not there, in publish.html, i get a button to download it, else the Run button will install the application (which is developed by me) . This works fine in all the machines, except for one in which i have the following versions of .NET Framework,
.NET Framework 3.0 Service Pack 2 3.2.30729
.NET Framework 3.5 SP1 3.5.30729
.NET Framework 2.0 Service Pack 2 2.2.30729
In this machine even though we have Framework 2.0 and higher versions, i am getting the button to download Framework. This is not correct. Can any one help me on how to overcome this problem.

Hi everyone,
I have a control who contains a repeater to display some Url whith some parameters below the code of the control
<ul class="chapiter">
<asp:Repeater ID="Chapiters" runat="server">
<ItemTemplate>
<%# ShowLink(DataBinder.Eval(Container.DataItem, "QuestionId"))%>
<a href="SaisiePage.aspx?onglet=2&idchapiter=<%# DataBinder.Eval(Container.DataItem, "QuestionId")%>">
<%# DataBinder.Eval(Container.DataItem, "Description")%>
</a>
</li>
</ItemTemplate>
</asp:Repeater>
</ul>
the problem that in href link i must make a POST to the page not a GET. th problem that for style reason i must keep the <li><a></a></li> to keep the style in the page.
is that possible, is there any trick to do it?
thanks you for help!

You could use xmlhttprequest, the same thing that you use for AJAX stuff.

ASALAMOALEKUM,
i am using ASP.NET WITH C# FOR my website.
I have an ONLINE table which stores the id of the user who signin to the site.
Now i want to delete the id of the user from the ONLINE table who signout by using SIGNOUT button or close my website from browser.
behind the SIGNOUT button, i have applied simple sql delete query which works properly but in case of closing browser i have tried the GLOBAL.asax event
APPLICATION_END() ... which contains the same delete query... but it doesnt workssss.. can anyone tell me why its not working ??
do we have to make any settings in webconfig filee??
but as i have put the same delete query in the Session_End() event of global.asax... after 24-25mins of closing the browser it hits and delete the id from the table... i dont want such a great delay...!
please guide if i am missing any imp point in my implementation!
thnks,
Regards,
SANA

You have mis-understood what Application_End is for. It is not for when a user closes the window, but instead is fired when ASP .NET is actually shutting down the web application. You can get lower timeouts by adjusting the session timeout in web.config.
|
|
|
|
|
Sounds like your after Session End in the Global ASAX. You need to kill the session when the user hits the signout by calling Session.Abandon(). That way you don't have to wait for the timeout.
|
|
|
|
|
well this is the solution for signout button only,
my major problem is with BROWSER closing event... i have to delete user's id from ONLINE table at this event.
My website is about chatting.... thats why this user's online/offline state is very important to manage... i cant let user's status remain be online if he/she has closed the application from browser...
