i m using nested grid and in child grid i m using EmptyDataTemplate in which i hv one htmlanchor tag which is redirecting to another page when that child grid is empty and i m passing parentgridrow id as query string parameter to that anchor tag.
here i m giving u code what i m using.
Protected Sub ParentGrid_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles ParentGrid.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
Dim s As SqlDataSource = CType(e.Row.FindControl("SqlDataSource1"), SqlDataSource)
s.SelectParameters(0).DefaultValue = e.Row.Cells(0).Text
CType(e.Row.FindControl("ChildGrid"), GridView).DataBind()
End If
End Sub
Protected Sub grdProduct_DataBound(ByVal sender As Object, ByVal e As System.EventArgs)
Dim grd As GridView = CType(sender, GridView)
Dim grdr As New GridViewRow(-1, -1, DataControlRowType.EmptyDataRow , DataControlRowState.Normal)
Dim cell As New TableCell
cell.ColumnSpan = 2
cell.Width = Unit.Percentage(100)
Response.Write(CType(sender, GridView).Rows.Count)
End Sub
it is giving output like shown below:
0
7
0
2
0
15
where 7 indicates 7 row of 1st child grid (child grid in 1st row of parent grid)
same way 2 and 15 also
means in my parent grid there r only 3 row (means there r only 3 child grid would created)
then why i m geting other three zeros. can any one explain me the execution flow for nested grid.
Thanx in advance,

This Event is firing twice. That is before DataBinding (Empty Grid), and after DataBinding (With Data).

in my application document.referrer is shown empty string ???
|
|
|
|
|
From MSDN Library:
"This property returns a value only when the user reaches the current page through a link from the previous page. Otherwise, document.referrer returns an empty string; it also returns an empty string when the link is from a secure site."
Also, some antivirus/firewall applications remove the referrer information from requests, so you can't rely on it always be there.
Experience is the sum of all the mistakes you have done.

hi,
i have a checkbocxcolumn in the datagrid..
i need to select only one checkbox..and if he selects more than one checkbox...it has to show a message that .."select only one checkbox"
how can i do this in asp.net

1) declare one variable in Javascript
2) set it as 0 by default.
3) write the javascript code
- if chk is checked then
if thisvariable less than 1 then set this variable to 1
else thisvariable is 1 then show the alert("select only one checkbox")
else // chk is unchecked
set thisvariable to 1
4) Add this code in onclick (client-side) event of checkedbox

Why don't you have a radio button in that column?

Hi,
in the gridview even if you put radio button then it will not solve problem.
Bcoz in grdview it will vreate dynamically radiobutton.
And you cant get result as you can get in simple radiobutton.

But with small programming trick, you can do it.

Did I tell that it will solve the problem? Have you ever seen in any web page having a list of check boxes in the same group, when user selects more than one prompting a message saying "don't select more than one". Don't that sort of design defeats the purpose of using Check boxes?

Hi Guys,
As I were said,
in datagrid / gridview if putting radio button then that will be in templatefield.
and if you know then its creating radiobutton at runtime for every row.
So cant assign group in that radio button.
So will you be with your radio button everytime ? 
What now ? any doubt ?
Thanks,
Sun Rays

I can understand that Using radio-button in a DataGrid will have the same effect as CheckBox. Will that be a problem if we write a JavaScript function to control the single selection of the radio-button list. There's another alternative too to sort this problem, by Adding a label and dynamically adding HTML input tag as Label Text with type as radio and runat server enabled and with the same group name. This works.

Try dynamically adding HTML Server Input Control with type radio and with the same group name.

Yes, when required.

Yes, Radio-Button Column on a DataGrid is the first Design-Template which I coded few years ago...

Hello all,
I have developed a web application in ASP.Net using C# with login credentials.
I am getting following problem with it.....
I am logging in as user "abc" from one computer in network, its working fine. At the same time, i m logging in as different user say "xyz" on other computer. After this, when i refreshes my "abc" user's page it shows all contents of "xyz" user and hence automatically expires session of "abc".
I am not getting where the actual problem is, please anyone of u can help me with this?
Here is my code......
private void BtnGo_Click(object sender, System.EventArgs e)
{
Label1.Visible=false;
bool persistcookie=true;
if(ValidateUser(TextBox1.Text,TextBox2.Text))
{
//string globalstrConn="Provider=SQLOLEDB;Data Source=localhost;Initial Catalog=iMedia;Integrated Security=SSPI;";
Session["UserName"]=TextBox1.Text;
//This will store the username of the user in this session variable
// We can retrieve this username on different pages by using following code.
// string str=Convert.ToString(Session["UserName"]);
FormsAuthenticationTicket tkt;
string cookiestr;
HttpCookie ck;
tkt=new FormsAuthenticationTicket(1,TextBox1.Text,System.DateTime.Now,System.DateTime.Now.AddMinutes(Convert.ToInt32(ConfigurationSettings.AppSettings["timeout"])),persistcookie,"Your Custom Date");
cookiestr=FormsAuthentication.Encrypt(tkt);
ck=new HttpCookie(FormsAuthentication.FormsCookieName,cookiestr);
if(persistcookie)
ck.Expires =tkt.Expiration;
ck.Path =FormsAuthentication.FormsCookiePath;
Response.Cookies.Add(ck);

Hi all!
I have such problem with IIS 6.0 configuration.
I have a web site with HttpHandler inherited class which catch all requests. When I publish this site on IIS 6.0 and try to launch this application by entering
"http://mydomain.com/test-www;par@act=value&Parameter=mypar" my site doesn't catch this request and IIS returns Bad Request (400) error
May be RFC 1738 Url Standard works here and IIS can't obtain such requests. But may be there is a way to solve this problem
Thank you very much in advance

IIS 6 has a wildcard mapping setting that is designed specifically to process requests that don't map to a specific file (i.e. a request with no file extension). When you configure your web site/app, click on the configuration button under the application settings. Under the application mappings, you should see a wildcard mappings section as well. Map the wildcard request to the aspnet_isapi.dll and make sure that it doesn't require that the file exist. That should solve your problem.

Hi All,
I have one doubt i have a data container class Applicant.i have created many objects of other classes like PersonalInfo,Employment..... etc
in the constructor of applicant.
Now the question is there any performace issue while using these 2 sentnces
string Address = applicantObject.PersonalInfo.Address;
Or should do in another way
PersonalInfo personalInfoObject=applicantObject.PersonalInfo;<br />
string Address=personalInfoObject.Address;
Is there any perforamance between 2
Address is a property it might have many properties
Can any one give me the link where i can read performance issue for this type
Thanks and Regards

Option 2 creates another reference to a class, or another copy of a struct. Either way, this is not going to have a huge hit.
