tell my what are you doing? are you adding any extra thing as i said remove the PreviousTag Tag from aspx as i can't predict the previous page it can be anyone (maximum cases you can't predict previous page)
Considering you are using VS 2005 can you post your code that you have written in pageload
Thanks and Regards

This was the code i used earlier.But i want to split this code so that each dataset in separate functions in class.There comes the trouble. CExWordMLFiller wfiller = new CExWordMLFiller(ds, xmlTemplateDoc.OuterXml);
This 'ds' comprises all datasets..
This is the new code..:
<code> public DataSet GetEmployeeCategory (int userId)
{
DataView dvTemplate = null;
int templateId=0;
string SP = DBObjectName.spGetEmployeeCategory;
Hashtable htParameters = new Hashtable();
htParameters.Add("@User_Id",MISUtility.CheckNull(templateId));
DataSet EmpCat = new DataSet();
try
{
OpenConnection();
dvTemplate = Connection.ExecuteProcedure(SP,htParameters);
DataTable dtTmp = dvTemplate.Table;
EmpCat.Tables.Add(dtTmp);
}
catch(Exception e)
{
throw new MISException("AdvancedReport.GetEmployeeCategory() failed",e);
}
finally
{
CloseConnection();
}
return EmpCat;
}
public DataSet GetEmployeeBasicQualification(int userId)
{
DataView dvTemplate = null;
int templateId=0;
string SP = DBObjectName.spGetEmployeeBasicQualificationList;
Hashtable htParameters = new Hashtable();
htParameters.Add("@User_Id",MISUtility.CheckNull(templateId));
DataSet EmpEdu = new DataSet();
try
{
OpenConnection();
dvTemplate = Connection.ExecuteProcedure(SP,htParameters);
DataTable dtTmp = dvTemplate.Table;
EmpEdu.Tables.Add(dtTmp);
}
catch(Exception e)
{
throw new MISException("AdvancedReport.GetEmployeeBasicQualification() failed",e);
}
finally

return EmpEdu;
}

A datatable will have only one table but a dataset can have multiple tables.
If you have data required from two tables then join those multiple tables and assign to a dataset then further to a datatable.
I guess....

hi friends
i have on ascx user control
on user control i have three textboxes
which are invisible
i have one button on ascx
when i press this button
these textboxes will get visible
when it gets visible i want to set focus on
one of these textbox
so i write one javascript
and form load
i write
btnAdd.Attributes.Add("OnClick","Setfocus()")
but in this case js code will execute first
text boxes are invisible
and i am not able to refer these textboxes in js
so i am not able to set focus
how can i solve this or any other way to solve this issue
pls help
thanks

btnAdd.Attributes.Add("OnClick","Setfocus()") ?
Are you writing it in ascx page load ?
that is important
In javascript only make them visible before seting focus
Thanks and Regards

Can't you make the Textbox read only first then after button click write javascript to make readonly =false and set the focus 
Thanks and Regards

If you use the Visible property of the server controls to make the text boxes invisible, they are not rendered to the final page, so they doesn't exist in the page at all. You can't access something that doesn't even exist.
You have to use any of the css properties display or visibility to hide the text boxes, so that they still exist in the page and can be made visible by changing the css style from Javascript.

Attach SelectedIndexChanged event to the dropdown.
And in the event connect to database to get all members
Nana

Private Sub dropdownlist1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles dropdownlist1.SelectedIndexChanged
dst = New DataSet
sqldad = New SqlDataAdapter("SELECT employee from tablename where projectname=val(dropdownlist1.selecteditem.value)", sqlconn)
sqldad.Fill(dst)
dst.Tables(0).TableName = "tblMainGRD"
If dst.Tables("tblMainGRD").Rows.Count > 0 Then
Me.btnSubmitStock.Visible = True
listbox1.DataSource = dst
listbox1.DataBind()
Else
Me.btnSubmitStock.Visible = False
listbox1.DataSource = Nothing
listbox1.DataBind()
End If
sqldad.Dispose()
dst.Dispose()
End Sub

Under SlectedIndexChanged event of dropdownlist write the code.
Based on the selected value of the dropdownlist, fetch the name of all the members from database and then bind the datalist with the data retrieved.

Iam developing a web based payroll system using Visual Studio 2005 and
ASP.Net. I would like to have certain clarification on the following line.
I would like to pick employee name from a list which contain multiple
colums with employee name,employee id,department as coumn headers. For this
if I use combobox - it can contain only one column, if I use listview and if
the no of employees are high the selection will become too slow. Can you
suggest any control which will support multiple columns and multiple records
(rows) with an area to enter some text value (employe name) which is to be
serched with in the displayed list ?
I also would like to know about a control (feature ) which supports data
entry in a grid format (rows and columns - Excel like data entry). The grid should suport data entry directly in to a cell. The grid also should suport data binding. I should be able to customise the column/cell format into textbox,combobox, etc. Is there any such inbuilt control available with Visual Studio 2005 ans ASP.Net ? If not, is it advisible to build a user control by ourself or buying a provern third party control ? If third party control is advisable can you suggest a well known and widely used one ?

I would suggest a datagrid for both of these things - for the first one add a check box column and for the second you need the grid to be in edit mode always.

You are running under the default aspnet account (anonymous access). This user does not (and probably should not) have permission to access your database.
