I had seen this question before
There might be a way...
1.- Implement a webmethod or a page function that deletes the session (I think that it is not posible to end the authentication ticket in this type of call)
2.- Using javascript in the clientside, call this function when the user is leaving the page
I dont know the javascript event where you need to make the server call, but just take a look at the post new message page here at codeproject and see how it warns you about loosing the info if you leave the page (hitting the backbutton or writing a new url in the address bar) on that event instead of warning (or you could warn as well) call the server function or webmethod in step 1
Now, if you do it like this, if the user hits the back button (Once he is in another website), he will be able to see the page but when a postback is done, check to see if it is a new session (or look for a session field that was set when the user logged in), if your condition is not met, log the user out and redirectit to login page
I hope you work it out, but i really think you are going to far, i dont see any problem leaving your app as it is

English obviously isn't your first language and so it is hard to understand your question. Are you asking how to get the selected indexes of a checkboxlist isnt a comma-separated string?
if so this is how I usually accomplish (assume cbl is your checkboxlist)
List<string> selectedIndicies = new List<string>();
for(int i=0;i<cbl.items.count;i++)>
{
if(cbl.Items[i].Selected)
selectedIndicies.Add(i.ToString());
}
string result = String.Join(",",selectedIndicies.ToArray());

Hi all,
I'm looking to bolt on Forum / Social networking features to my site www.workoutbox.com (which is still under development). WorkoutBox is completley custom built from the ground up and runs on MS SQL 05.
The forum / social networking features I'm looking to add are very similar to these:
http://www.gyminee.com/forums
http://www.gyminee.com/groups/search/1[^]
Basically a nice clean Web 2.0 forum, with groups and profiles, thats easy to use and not over the top.
I now have two options, either have my freelancers build the forum, profiles and groups from the ground up, or use an open source forum engine like http://forum.yetanotherforum.net[^] and intergrate / reskin it into the site and plug in into my existing login / registration system.
I'n theory the open source route sounds quicker, but since I'll probably want to extend/customise whats there a fair bit anyway, that could give me more hassle than its worth. I'd really be greatfull for some outside advice on this one, as bad decisions here can turn your development project into a nightmare..
Thanks guys,
Simon

Simon, it is really a tough call.
As a .net programmer I would normally say build your own. However, forums have been done so many times that I am thinking it would be easier to use the open source forum. You might have to make a few minor design sacrifices, but it will save you time and money in development costs.
Really it is up to you though. Your site looks cool, I might just sign up when it is done.
I didn't get any requirements for the signature

I'd say it comes down to cost. If you want a fully customised forum then obviously you have to have it developed, which would probably be more expensive than taking an open source one. I suppose the other thing to consider is how open source is it? If you have the source code then its a very good starting point to extend from.
Always a difficult decision, but at the end of the day is it worth spoiling the look and feel of the site for the sake of a few more quid?

Hello
I try to use an Imagebutton instead of a LinkButton in my gridview to select and to delete a specific row but when using the asp.net application and press the image it will give this error:
"Invalid postback or callback argument. Event validation is enabled using <pages enableeventvalidation="true"> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
"
Please help
And tahnks in advance

Hi All,
I hope all are doing good.Anyway
I need your help in calling webservice. I have one page with Address fields like address,city,State ans zipcode
Now i have to call a service and have to pass Address values to the service. Again before calling service i have to Validate these fields at server side if all things are right then call should made to service. After calling service I need to display dynamic text depending on the service result.
Now the question is which is better way to call the service
1. using Ajax and call the service from the function present at server
2.Is there any way to call service from JQuey but how to Validate my form fields (Custom Validation is at server no client side validation).
3. Can i use Page Methods for this but i need to update some fields on the page (Validation).
Any Ideas ?
Note: I can't make client side validation as i need to check State and zipcode value, User should provide correct zipcode for the state he has selected

Go with server side calling
You can use Ajax also if it is already present on the Page then only use it .
As u can't perform validation at client side there is no meaning in calling service using javascript
Thanks and Regards

Hi All,
Please give me a solution to close a firefox browser with javascript.
I have written the following code, but it is not working on firefox.
function closeWindow() {
window.open('','_parent','');
window.close();
}
Waiting for reply.

javascript:void(window.close())
Put that in the PostBackUrl of the asp.net button
The answers posted by me are suggestions only and cannot be used in anyway against me.

Thanks... .netman
but it is still not working.
my code is:
<asp:button id="Button1" runat="server" text="Button" postbackurl="javascript:void(window.close())" xmlns:asp="#unknown">
D'kng

d'kng wrote: window.open('','_parent','');
What is that ?
you need to close the browser on button click
Register this javascript onclick event of button at server side
ButtonID.Attributes.Add("onclick", "javascript:closeWindow();");
and javascript function is
<script language="javascript" type="text/javascript">
function closeWindow() {
window.close();
}
</script>
if you don't want to show any confirm message before closing then write
window.opener = self;window.open('','_parent','');window.close();
Thanks and Regards

In the user control I have
<asp:imagebutton id="ImageButtonBanner" runat="server" xmlns:asp="#unknown" />
and in the user control Page_Load event I set:
this.ImageButtonBanner.ImageUrl= "~/naitaBannerit.aspx?pictureId=0";
In the naitaBannerit.aspx page I read picture from databse VARBINARY(MAX) field with additional info like:
string pildiID = Request.QueryString["pictureId"].ToString();<br />
SqlConnection myConnection = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["connString"].ToString());<br />
myConnection.Open();<br />
SqlCommand myCommand = new SqlCommand("dbo.AD_PICTURE_KUIDO_S", myConnection);<br />
myCommand.CommandType = CommandType.StoredProcedure;<br />
myCommand.Parameters.AddWithValue("@pictureId", Convert.ToInt32(pildiID));<br />
SqlDataReader rd= myCommand.ExecuteReader();<br />
while (rd.Read())<br />
{<br />
Response.ContentType = rd["TYYP"].ToString().Trim();<br />
byte[] imageContent = (byte[])((rd["PICTURE"]));
//and I also add additional info from database to Response.AppendHeader
Response.AppendHeader("laius", rd["width"].ToString());<br />
Response.AppendHeader("korgus", rd["height"].ToString());<br />
Response.AppendHeader("reklaamilink", rd["LINK"].ToString().Trim());<br />
Response.BinaryWrite(imageContent);<br />
break;<br />
}<br />
rd.Close();
Is it possible to use these Response.AppendHeader with asp:ImageButton control
like
this.ImageButtonBanner.PostBackUrl = HttpContext.Current.Request.Headers["reklaamilink"].ToString();
or how to capture ImageButton call to/from ImageUrl ?

Ah, in your subject it says autohide. You could put the treeview control inside the sliding menu.
