Ok thanks for that. I had a brief look at Gaussian but looks like it could be slightly overkill for my requirements. I also couldnt see how u would tie that into my problem of having what is basically an array from the database of unique numbers and how to select one of these?

Any other ideas? or examples?

Thanks

The Gaussian numbers can be used to get a set of random numbers which could be used as the index of the array. If you have 1000 records in your database, you can have your Gaussian function return 10 values(according to how many you need) between 0 and 999. Use the numbers generated as the index and pull out those from the array.

The reason I suggested this is because it follows a uniform distribution and your draws would not follow a pattern.

Don't suppose you know of any good examples regarding this before I go looking?

You can have a look at this thread[^]. I wrote the function using the formula I found online, you probably have to search online to find if some code is available.

Hi all,

I have an aspx page which contains a hiddenfield ..i have javascript in the samepage which contains the following piece of code..

function PostPage()
{
var popup;
document.form1.action = "Default6.aspx";
document.form1.method = "POST";
document.form1.submit();
}

and the aspx page contains the following

<asp:ImageButton ID="ImageButton1" runat="server" OnClientClick="Javascript:PostPage()" />

with the hidden field populated from codebehind...

Now i want the Default6.aspx to be opened as a pop-up after submitting the current page.I need to submit the page instead-of using 'window.open' coz i'can retrieve the hiddenfield value in the popup page...

Overall my question is that when i click on the imagebutton the javascript submit() should occur annd then the new page should be opened as popup ..how to do that? please let me know

i guess problem is due to parameters i am passing in Qry strin that every time parameters are passed again and results comes same instead of next page

on Page load i have this code
If Not Page.IsPostBack Then
bind SQL
end if

BindSQL()
'DSgrid is a data.dataset
'DB is a object of a class where i make connection

dsgrid = db.getRecords("SELECT attendence.EmpNo, Strength.Name,convert(varchar,Strength.DOJ,101)as DOJ,Strength.EmpStatusid,convert(varchar,attendence.Date,101)as DDate,convert(varchar,attendence.InTime,108) As InTime,convert(varchar,attendence.OutTime,108)As OutTime,attendence.Present AS Status,convert(varchar,(OutTime-InTime),108)As WorkedHrs FROM attendence INNER JOIN Strength ON attendence.EmpNo = Strength.EmpNo Where attendence.EmpNo ='" & cempid & "'AND attendence.Date >= '" & mfromdate & "' And attendence.Date <= '" & mtodate & "' Order by Date")

Dim mtcheck As Integer = dsgrid.Tables(0).Rows.Count()
If mtcheck = 0 Then
lblerror.Visible = True
Label3.Visible = False
Label5.Visible = False
lblerror.Text = "No Record Found"
Else

DG_CheckBox.DataSource = dsgrid
DG_CheckBox.DataBind()
End If

End Sub

Sub myDataGrid_PageChanger(ByVal Source As Object, ByVal E As DataGridPageChangedEventArgs)
DG_CheckBox.CurrentPageIndex = E.NewPageIndex
BindSQL()
End Sub

Didnt understood this function
Sub myDataGrid_PageChanger(ByVal Source As Object, ByVal E As DataGridPageChangedEventArgs)
DG_CheckBox.CurrentPageIndex = E.NewPageIndex
BindSQL()
End Sub

I Think it should be like this
Sub DG_CheckBox_PageChanger(ByVal Source As Object, ByVal E As DataGridPageChangedEventArgs)
DG_CheckBox.CurrentPageIndex = E.NewPageIndex
BindSQL()
End Sub

Hope this helps u...

how to edit DropDownList [modified]

9-May-07 20:34

I have Change your code please,

'Bind GridView Method
Public Sub BindGridView()

Dim oDS As New DataSet

strSql = "Your Query"

oDS = db.ExecuteDataSet(strSql)
DG_CheckBox.DataSource = oDS
DG_CheckBox.DataBind()

End Sub

'Return Dataset
Public Function ExecuteDataSet(ByVal strsql As String) As DataSet
Dim dtad As SqlDataAdapter
Dim dtst As DataSet
dtst = New DataSet
dtad = New SqlDataAdapter(strsql, GetConnection)
' GetConnection Get the sql connection
dtad.Fill(dtst)
CloseConnection()
Return dtst
End Function

Protected Sub DG_CheckBox_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles DG_CheckBox.PageIndexChanging
Try
DG_CheckBox.PageIndex = e.NewPageIndex()
BindGridView()
Catch ex As Exception

End Try
End Sub

U Can use EmptyDataText if your query doesnt returns any records.
eg: EmptyDataText = "No Record Found"
Else u can use your code also for showing error "No Record Found"

Hope this helps u...

Hi,

I am looking for a rental system like for videos or property, it must be open source. Does any one know of something like this?? It must preferably have a back office and must be integrated into a payment gateway, like Pay Pal for example. But the payment gateway is not required, I'm also looking for a rental calendar, where a user can look at what dates a property has been booked for.

Please can someone help me out.

Regards

you can add item at run time

<br />
 DropDownList1.Items.Add(new ListItem("text","Value"));<br />

I think you can't do it using drop down list .
You can go with different approach by Adding one more TextBox
When user selects item from drop down list it will get into text where you can Edit it and After editing Add back to drop down list ...

Thanks and Regards
