Replace first line of show function with below code
var ctrl = document.getElementById('<%=FreeTextBox1.ClientID%>');

It might help you.

a type that does not accept the focus. FormBuilder.aspx, line 651 character 9

Make sure that your text box control(FreeTextBox1) is enabled and visible. if not then first enable it then set the focus otherwise it gives an error.

Well, there's many errors here

1 - you asked in the wrong forum
2 - string mashing SQL is never wise
3 - you don't tell us why you think there's an error

I would use the debugger in this situation to read the sql, then look at it and try it in the query analyser to work out what is wrong.

Interesting problem when opening a PDF file inside iFrame element in an aspx file

HI,

If I am posting this in wrong category please advice me the right one. I am really not sure...

Here is the problem i have,

I have a PDF document that has

1. intranet link (http://server/guideline.aspx)
2. internet external link (http://www.google.com)
3. physical link to a file in a server (file:\\localserver\shared\guideline.html)

When I open this PDF file in adobe all of the above 3 links works very fine and take me to the right page/document.

When I open this PDF file in IE all of the above 3 links wokrs very well and takes me to the right page/document.

But in my .NET 2.0 C# application I am trying to open this up by a aspx page using iFrame, it opens up very well and first 2 links works very well. When i click the third link I am receiving "Page cannot be found" error. I checked the property of this page and looks like IE is trying me to open up
http://localhost/localserver/shared/guideline.html
instead of
file:\\localserver\shared\guideline.html

I spent 3 days finding a answer to this problem But no luck.

Here is the code in side aspx page:

<body id="bdContent" bottomMargin="0" leftMargin="0" topMargin="0" rightMargin="0" runat="server">
<form id="Form1" method="post" runat=server >
<iframe id="frmBrowser" marginWidth="5" hspace="0" vspace="0" src="medseed.htm"
width="100%" height="100%" runat="server" scrolling="auto">
</iframe>
</form>
</body>

This is the code I am using to load the PDF file dynamically,

string script = String.Format("<script>document.all.frmBrowser.src='{0}';</script>", url);
RegisterStartupScript("scriptBreakframe", script);

Here url is the the actual URL for PDF something like this http://localhost/workingproject/guidleine/linksfile.pdf

Anyone faced this problem before?? Please please.. anyone know the solution?

THanks in advance for your valuable time.

Cheers

i'm trying a simple incremant in asp.net using a thread, in the debug mode the values are correct and assigned to the label1 properly. but at the end th label value is not changed as it showed in the debugging mode.

public delegate void mydel(int y) ;
    public mydel m;

       protected void Button1_Click(object sender, EventArgs e)
    {
        if (IsPostBack)
        {
            Thread thrd = new Thread(new ThreadStart(dothis));
            thrd.Start();
        }
    }

    private void dothis()
    {
        for (int x = 0; x < 5; x++)
        {
            m= new mydel(update);
            m.Invoke(x);
        }

    }

    public void update(int a)
    {
        this.Label1.Text = a.ToString();
    }

what might be the problem.

The basic issue is your understanding of ASP.NET. You basically have a race condition. If your page lifecycle ends before the threads have run, they will die.

If you are using .net framework 3.5 then use LINQ as follows

var query = (from c in dt.AsEnumerable() select new { FirstName = c.Field<string>("FirstName"), LastName = c.Field<string>("LastName") }).Distinct() ;

It will give you distinct values.

Hi Aijaz,
But if you are working on framework 3.5 then you can use the code i have posted above.
If not then you might be need to create dataview and then filter rows from there.

You can try hashtables for doing this.
But the best way is to change the display at runtime by merging the cells in gridview.
You can have a look at this:
