First of all from where the user tray comes into the scene? Confused | :confused:

Anyway, what I understood is, you have a web application in which you want a particular page to be opened only by an user at a time. Am i goin right?

Well, I can not understand the reason why you are doing this, but solution can be very simple.
Maintain a application state, and store information in it if some one has already opened in it.
Display the message accordingly. Rose | [Rose]

And how do you want to determine that a user closes the page?? Other from that... use the Application[] variables...

Application["InUse"] = true;<br />

use applicatoin object in the way
let suppose add this statement on page load.
if (Application["PageState"] == null)
{
Application["PageState"] = "Opened";
}
else
{
Application["PageState"] = null;
}
this object is application level and is visible to all users.

Re: I need to get the TEXT property of the HyperLink control

Hello,

can somebory tell me how can I get the TEXT property of the HyperLink control like I can get the TEXT property of Textbox, for example: string username = TextBox1.Text;

when I'm trying to put Hyperlink1 instead of TextBox1 it gives me exception: System.NullReferenceException: Object reference not set to an instance of an object.

Thank you!

Re: I need to get the TEXT property of the HyperLink control

15-Jul-07 23:47

may be it is because I'm using it this way:

HyperLink usernameh=(HyperLink) DataList1.FindControl("Hyperlink1");<br />
        string username = usernameh.Text;

i do think so coz sometime "DataList1.FindControl("Hyperlink1");" this may return null value if there is no control found. Keep a break point and check wheather your code is returning any controls or not.

Thanks

This means that your hyperlink object is not present in ASP XML page.
or you have not saved XML page yet. (You have only save code behind page).
use this control for hyperlink.
<asp:linkbutton id="LinkButton1" runat="server">LinkButton
or use
LinkButton

I understand now, it is because there is only one HyperLink1, but the DataList have many rows...

Datalist is for viewing data. For this purpose you place the hyperlink in gridview and the on RowDataBound event please write.

protected void grdMain_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
UploadInfo uploadInfo = new UploadInfo();
LinkButton dr = (LinkButton)e.Row.FindControl("LinkButton1");
}
}

Thank u very much, but I didn't understand, did u mean Hyperlink instead of Linkbutton?

my code used to be like this:

protected void btnApprove_Click(object sender, EventArgs e)<br />
    {<br />
        HyperLink usernameh=(HyperLink) DataList1.FindControl("Hyperlink1");<br />
        string username = HyperLink2.Text;<br />
        SqlDataSource1.UpdateCommand = "UPDATE Users SET newuser ='" + true + "' WHERE (username='"+username+"')";<br />
        SqlDataSource1.Update();<br />
    }

Thanks!
