Can you paste the actual code where the error occurs?

1)To start with open a connection(oracle)
2)Create a command object.
3)Since you are a learner give direct query as command text
4)the query shoule have what you want to obtain according to the clients' selection
5)you can use datareader or dataadapter as well.
6)if using datareader give commandname.executereader()

I have a Datagrid in which iam displaying EmployeeName and sum other details.
The employeeName In the Datagrid is a Hyperlink Column fromwhich i open another Employee Form in edit mode.I want to disable the hyperlink for normal users.
I have tried disabling the link using : e.Item.Cells(1).Enabled = False
But it is still clickable. I dont want it to be clickable. How to go about in doing this?
following is the aspx code:
<asp:HyperLinkColumn DataNavigateUrlField="EmpId" DataNavigateUrlFormatString="FrmEditEmp.aspx?EmpID={0}" DataTextField="EmpName" HeaderText="EmpName">
<ItemStyle Width="20%"></ItemStyle>
</asp:HyperLinkColumn>

there are many ways, but if i do this then i will suerly hide it...
e.Item.Cells(1).Controls[0].visible=false;
u can also try
e.Item.Cells(1).Controls[0].Enabled = False; this is in c#

hi,
when you give simply cells[..] it considers to be as normal text, in your case there is a control in the cell i.e. a link in your cell, so try e.item.cells[1].controls[0].enabled=false;
hope this works!!!

Hi All,
I get number of records when I fire a query in DataTable.There are 3 Columns namely columndatatype,columnname and displaycolumnname.Now I want the displaycolumnname to be display in listbox and combo and other 2 with displaycolumnname in Gridview where other 2 sould be visible false.
Please tell me how do I go about this.I need help in code.
Thanks in advance.

I have 2 tables first has ID,TableName,ViewName and other has ID,FirstID,ColumnName,DisplayColumnName,ColumnDataType.
What I want is to fill listbox and combo with DisplayColumnName and in GridView I want DisplayColumnName as Visible True and ColumnName and ColumnDataType as Visible False.
But I am using Viewstate datatable to bind GridView runtime.So I need to use Arraylist index so that I can use that index to bind the visible false columns with the respective DisplayColumnName.
Now I want a single Arraylist which will have ColumnName,ColumnDataType and ColumnDisplayName and when I put ColumnDisplayName in GridView I want ColumnName and ColumnDataType at the same index as of ColumnDisplayName.
Hope u understood what I want to do??
Please help me for the same.

pls help me in writing asp.net code for 'ticket avaliability' module of travel & tourism project.I've just started learning .net so kindly help me out.

It solely depends upon your reqirement. Lets say you have availabilty for specific source-destination for all dates. so whenevr a user selects his/her source, destination, date of travel, no. of tickets decresae the avaialbilty in the databse according to the no. of tickets.
Basic idea! what have you done so far??

Hi,
I believe Master Page is not a problem.
SharonRao wrote: "window.opener.document.forms(0)." </blockquote>
Here forms(0) may not represent your Master Page.
Soln:
Try Use, document.getElementById('') and Pass the ClientId of your server control (TextBox) to the Popup Calendar. Hopefully it works fine.
