Hi,
You can use Onitemdatabound event of the datagrid to do this. What you need to do is in that event you just check for the edititemtype and then bind the dropdownlist.
Hope this will help you.
BTW This you better post in asp.net forum.

Hi Apurva,
Thank you for your kind response,
The code I metioned earlier is inside the Onitemdatabound and before binding I am checking the ‘ListItemType.EditItem’. I am getting problem when I try to get the reference to the control using the below code inside he event handler. Please check this below code
Dim cmb As New DropDownList
If e.Item.ItemType = ListItemType.EditItem Then
cmb = e.Item.Cells(4).FindControl("ddlCountry")
End If
In the above code ‘ddlCountry’ is the dropdown list control id. If I add this control in the Item Template instead of Edit item template I get reference to it.

Hi,
Directly use e.Item.FindControl("ddlCountry").

Sir,
i tried following options.
strConString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\127.0.0.1\D:\News\News\bin\News.mdb"
strConString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\computername\D:\News\News\bin\News.mdb".
But these are not working.
Thanks for your reply

You are first trying to connect to an MDB on your local machine right?
If so, the Data Source parameter is malformed for a local path. That's what the error message has told you already.
Try copying the path you specify into the address box of Windows Explorer and see what it tells you. Now modify it until it works and then you should be able to use that in your connect string.

Hi,
with windows explorer i found this code will work.
strConString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\127.0.0.1\D\News\News\bin\News.mdb"
Thanks for your valuable help.

================================================
and code behind

and in function getRecords i am doing

Dim bizProgName As String = Request.QueryString("bizProgId")

dr = da.SelectCommand.ExecuteReader(CommandBehavior.CloseConnection)
If dr.HasRows Then
'lblError.Text = ""

I don't see the placeholder in your aspx code.

Where is dlScChart defined and created?
You also may get better results if you posted this question in the right forum.

Just an Idea as its not letting me post asp scripts as a whole
----------
datalist id="dlScHead"
ItemTemplate
| .. ctype(DataBinder.Eval(Container.DataItem,"ScoreCardID"),string).. |
datalist ID="dlScChart" DataSource=..(GetRecords(Cstr(DataBinder.Eval(Container.DataItem, "ScoreCardId")))) ..
ItemTemplate
<asp:placeholder id="Placeholder1" runat="server">
/ItemTemplate
<%# Server.htmlDecode(DataBinder.Eval(Container.DataItem,"Quarter1").tostring()) %>
<%# Server.htmlDecode(DataBinder.Eval(Container.DataItem,"Quarter2").tostring()) %>
<%# Server.htmlDecode(DataBinder.Eval(Container.DataItem,"Quarter3").tostring()) %>
<%# Server.htmlDecode(DataBinder.Eval(Container.DataItem,"Quarter4").tostring()) %>

/ItemTemplate
/asp:datalist

No it means nothing to me.
Like I said - post your question in the right forum (hint: try ASP.NET or Web Development). You may get an answer there.
This forum is for VB/VB.NET questions.
Also a hint for pasting code..... check the checkbox named Ignore HTML tags in this message (good for code snippets).

Like 95% of people, you're jumping in too deep. If you're new to VB, learn he langue first, then worry about databases.

How can I create a batch file using vb.net and then execute the batch file by clicking a button on the form. After the batch file has finished executing, it will be deleted.
Thank you for any reply

A batch file is just text. Just create a text file, called something.bat. Process.Start will run it.

or
You can simply do it using shell function without creating a batch file.
Shell("CommandLine1 & CommandLine2", AppWinStyle.Hide)

When I run my application, and type letter “a” (letters), I need to type a Unicode character(s) instead of letter “a”(in word pad or any word processing application). I have seen applications like that, but I have no idea how to do that
Do you have any ideas?
Thank You,

Wonder if any of you guys could point me in the right direction? Everywhere I've searched on Google always shows me how to do this with a datagrid - but not a form - and it just doesn't seem to want to work how I want it work.
I've created a form which correctly displays all my fields in a recordset. I can scroll through them, add new records, delete records, etc. etc. and everything is fine.
I now want to add a Search field to the form so that when the user enters a search string, it automatically searches through the dataset for EITHER the CompanyName OR the CompanyID - and refreshes the display to display the appropriate search result (ie. populates the currently open form with the appropriate record).
-- modified at 18:21 Wednesday 31st May, 2006
I partly figured it out - but can't get it to work with an OR part of the SQL. Any advice would be appreciated. The CompanyID is an Autonumber field.
Dim strSearch As String = "SELECT * FROM tblCustomersParent WHERE CustomerName Like '%" & txtSearchString.Text & "%'"<br />
<br />
Me.OleDbSelectCommand1.CommandText = strSearch<br />
Me.LoadDataSet()
|
|
|
|

Are you trying to do a like on the auto number field?
"SELECT * FROM tblCustomersParent WHERE CustomerName Like '%" & txtSearchString.Text & "%' or CompanyID = " & txtCompanyName
You should really look at using parameterized queries as well.

Hi - yes, the query was pretty much like you've suggested. I had tried:
"Select * From tblCustomersParent Where CompanyName Like '%" & txtSearchString.Text & "%'" & _<br />
" or CompanyID Like '%" & txtSearchString.Text & "%'"
and then...
"Select * From tblCustomersParent Where CompanyName Like '%" & txtSearchString.Text & "%'" & _<br />
" or CompanyID Like " & txtSearchString.Text
... and ended up just commenting out the OR bit 
What do you mean when you say, "parameterized queries"? Could you show me an example?
