Hi,
You can use like this:
"select * from tbl_access where user_id ='" & TextBox3.Text "'"
Hope this will help you.

You should look into using a parameterized query instead.
Both examples that you got are totally open to SQL injection attacks.

Hi All,
I have Data Grid on aspx page. One of the column in that grid is a Template Column. I have added a Drop down list in EditItemTemplate. If I add this in ItemTemplate I am able to bind the DropDownList in code behind by making a reference using the below code:
e.Item.Cells(4).FindControl("ddlCountry")
But when this control is present in EditItemTemplate I am not able to get the reference to the above control. Can anybody suggest me how to go ahead with this situation?
Thank you,
Krishnaraj

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.

strConString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\127.0.0.1\D\News\News\bin\News.mdb"
Thanks for your valuable help.

aspx page is:
<asp:datalist id="dlScHead" runat="server" showfooter="False" showheader="False" cellspacing="0"
="" cellpadding="0" width="100%">
<itemtemplate>
<%# ctype(DataBinder.Eval(Container.DataItem,"ScoreCardID"),string) %>

<itemstyle verticalalign="Top" backcolor="#EEEEEE">
<itemtemplate>
<asp:placeholder id="Placeholder1" runat="server">

<%# Server.htmlDecode(DataBinder.Eval(Container.DataItem,"Quarter3").tostring()) %>
<%# Server.htmlDecode(DataBinder.Eval(Container.DataItem,"Quarter4").tostring()) %>
|
================================================
and code behind
--------------------
in page load event i am doing
dlScHead.DataSource = GetRecords(Nothing)
dlScHead.DataBind()
and in function getRecords i am doing
Function GetRecords(ByVal scID As String) As SqlDataReader
Dim bizProgName As String = Request.QueryString("bizProgId")
Dim CommandText As String
Try
objConn = New SqlConnection(dbPath)
objConn.Open()
If scID = Nothing Then
Dim da As New SqlDataAdapter
da.SelectCommand = New SqlCommand
da.SelectCommand.Connection = objConn
da.SelectCommand.CommandText = "select scorecardId,bizProgId,scorecarddesc,businessgoal,strategy,quarter1,quarter2,quarter3,quarter4 from textData where bizProgID='" & Request.QueryString("bizProgId") & "'"
dr = da.SelectCommand.ExecuteReader(CommandBehavior.CloseConnection)
If dr.HasRows Then
'lblError.Text = ""
Else
'lblError.Text = "No records returned"
End If
GetRecords = dr
Else
cmd = New SqlCommand("select distinct measure_id from measuredata where scoreCardId = '" & scID & "'", objConn)
Dim da As SqlDataAdapter = New SqlDataAdapter(cmd)
Dim dtid As New DataTable("measureid")
da.fill(dtid)
'select all columns with id
Dim cmd1 As SqlCommand = New SqlCommand("select * from measuredata where scorecardid = '" & scID & "'", objConn)
Dim da1 As SqlDataAdapter = New SqlDataAdapter(cmd1)
Dim dt As New DataTable("measuresource")

Dim myview As New DataView(dt)
' dim chart as new mycos.mycoschartweb
myview.RowFilter = String.Format("measure_id='{0}'", datarow.Item("measure_id"))
chart.DataSource = myview
chart.DataBind()
Dim i As Integer
For i = 0 To dlScChart.Items.Count - 1
dlScChart.Items(i).FindControl("placeholder1").Controls.Add(chart)

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).
