I I am selecting a binary Image from the database with a SELECT query and I would like to display it in a webform but specifically a image control.
This is my code for selecting the image along with other attributes:

Dim bytes As Byte()
Using br As BinaryReader = New BinaryReader(FileUpload1.PostedFile.InputStream)
bytes = br.ReadBytes(FileUpload1.PostedFile.ContentLength)

I have used ListView Control to gets list of products from database. I also stores result in viewstate . Now to apply filter from checkbox to get refined data I want to know how can I use viewState values?
e.g. If 10 Products found in Music category when page loads. Now if user apply filter(Bluetooth) then only that products should be shown which are in Music & has bluetooth..
Now It is working Like on page load Music category gets fetched Then if I check Bluetooth filter then all bluetooth products comes which are not related to music.
Private Sub shop_Load(sender As Object, e As EventArgs) Handles Me.Load
Dim pageName As String = Me.Page.RouteData.Values("category").ToString()
if not Me.isPostback Then
Try
query = select * from products where category = '"+pageName+"'
Dim conString As String = ConfigurationManager.ConnectionStrings("conio").ConnectionString
Dim con As New MySqlConnection(conString)
Dim cmd As New MySqlCommand(query)
con.Open()
Dim da As New MySqlDataAdapter()
cmd.Connection = con
da.SelectCommand = cmd
Dim dt As New DataTable()
da.Fill(dt)
ViewState("Data") = dt
products.DataSource = dt
products.DataBind()
catHeading.Text = pageName
itemCount.Text = dt.Rows.Count.ToString
con.Close()
Catch ex As Exception
Response.Write(ex)
End Try
End If
End Sub
Filter Apply code
Private Sub priceFilter_SelectedIndexChanged(sender As Object, e As EventArgs) Handles priceFilter.SelectedIndexChanged
'buildWhereClause()
Dim price As String = priceFilter.SelectedValue.ToString()
Dim dt As DataTable = DirectCast(ViewState("Data"), DataTable)
Dim dr As DataRow() = dt.[Select]((Convert.ToString("category='") & price) + "'")
products.DataSource = dt
products.DataBind()
itemCount.Text = dt.Rows.Count.ToString
End Sub
I just want when user apply any filter then it should check from viewstate(Data) rather to entire table.
Save your category in viewstate & on Checked get that category in string & join that string in your query. something like this
Dim constr As String = ConfigurationManager.ConnectionStrings("connectionstring").ConnectionString
Dim query As String = "select * from table"
Dim joiner As String = ""
Dim condition As String = String.Empty
Dim whereClause As String = String.Empty
Dim priceCondition As String = String.Empty
Try
Dim category As String = ViewState("Data")
condition = String.Concat(condition, joiner, String.Format("{0}", category))
If joiner = "" Then joiner = ""
joiner = " where "
If Not String.IsNullOrEmpty(condition) Then
whereClause = String.Concat(whereClause, joiner, String.Format("category Like '%{0}%'", condition))
joiner = " and "
End If
'Same way you can apply multiple filters as you want & then get that in one string like below
Dim masterClause As String = String.Empty
masterClause = (query & whereClause)
Using con As New MySqlConnection(constr)
Using cmd As New MySqlCommand(masterClause)
Using sda As New MySqlDataAdapter(cmd)
cmd.Connection = con
Using dt As New DataTable()
sda.Fill(dt)
products.DataSource = dt
products.DataBind()
itemCount.Text = dt.Rows.Count.ToString
End Using
End Using
End Using
End Using
For your filter you could use :
Dim dt As DataTable = DirectCast(ViewState("Data"), DataTable)
Dim dr As DataRow() = dt.Select("category='" & category & "'")
products.DataSource = dr
products.DataBind()
itemCount.Text = dr.Length

I was verify if the boolean is True or False. If it false, it will change the server Name text to color red, if True, it doesn't change color. The SQL was able to read server Name that doesn't change text color but couldn't read the server Name colored red text and got SQL error message,
System.Data.SqlClient.SqlException (0x80131904): Incorrect syntax near 'red'.
Here is the VB code:
Dim sqlConn As New System.Data.SqlClient.SqlConnection((ConfigurationManager.ConnectionStrings("SOCT").ConnectionString))
Dim strSqlSecondary As String = "SELECT [Name], [Compliance] FROM [dbo].[ServerOwners] where SecondaryOwner like #uid order by [name]"
Dim cmdSecondary As New System.Data.SqlClient.SqlCommand(strSqlSecondary, sqlConn)
cmdSecondary.Parameters.AddWithValue("#uid", TNN.NEAt.GetUserID())
Dim dr As System.Data.SqlClient.SqlDataReader
Try
sqlConn.Open()
Dim root As TreeNode
Dim rootNode As TreeNode
Dim firstNode As Integer = 0
'Load Primary Owner Node
'Create RootTreeNode
dr = cmdSecondary.ExecuteReader()
If dr.HasRows Then
'Load Secondary Owner Node
'Create RootTreeNode
root = New TreeNode("Secondary Owner", "Secondary Owner")
TreeViewGroups.Nodes.Add(root)
root.SelectAction = TreeNodeSelectAction.None
rootNode = TreeViewGroups.Nodes(firstNode)
'populate the child nodes
While dr.Read()
Dim child As TreeNode = New TreeNode(dr("Name"), dr("Name"))
Dim complianceFlag As Boolean
If Boolean.TryParse(dr("Compliance"), complianceFlag) Then
' Yes, compliance value is a Boolean, now set color based on value
If Not complianceFlag Then
child.Text = "<div style='color:red'>" + child.Text + "</div>"
End If
End If
rootNode.ChildNodes.Add(child)
child.SelectAction = TreeNodeSelectAction.None
End While
dr.Close()
The error came from this line code because it read "red":
child.Text = "<div style='color:red'>" + child.Text + "</div>"
The child node text is passing when I click link to update,

If I get rid of Div tag, everything is work fine except there won't be colored red. How they able to read Div style which they should ignore the style and focus on child text. Is there a way to fix?
If you store the Name in the .Tag property of the child, you get to be able to use it regardless of what you do to the .Text of the child:
While dr.Read()
Dim myName as String = dr("Name")
Dim child As TreeNode = New TreeNode(myName , myName)
child.Tag = myName
Then in LinkButtonConfirm_Click
Dim x As Integer = 0
For Each item As TreeNode In TreeViewGroups.CheckedNodes
If item.Depth <> 0 Then
'append to select statement
strSql.Append(" [Name]='" & CStr(item.Tag) & "' or ")
x = x + 1
End If
Next
But you should still be adding the CStr(item.Tag) as SQL parameters. You already have a counter x in the loop which you can use to construct parameter names ("#p0", "#p1" etc.).
Edit: which would result in the Click handler looking something like

#Andrew Morton - Your theory are correct about error in strSql.Append(" [Name]='" & item.Text & "' or ") in LinkButtonConfirm_Click. I changed to strSql.Append(" [Name]='" & item.Value & "' or ") by replacing Text to Value. Now everything worked!
I am connecting to a database and then using an SQLDataReader to parse through those results and then put those results into variables that I can use at a latter time. The problem is that all of my "results.items" are returning null values. The DataReader is however, showing the proper field count when I debug.

we need to compare the content of 2 identical gridviews and extract rows that differ in a third gridview, is this doable?
i tried a lot but faced no luck, please help me.
at our office we take daily backup of ASP.net application ms access backend
for the next few days we need to evaluate the changes made to records in the database tables
at the end of each day i want to compare 2 access databases first database is the backup of yesterday and second database is the backup of today
i thought of the following algorithm, please read carefully and tell me how to proceed to compare the datatables / gridviews
i need to display th rows / cells containing the differences / updates / deleted data

I usually compare it using LINQ
This will give you a head start
var SearchResults1 = from u in YourDB.YourUserTable1
orderby u.YourColumn
select u;
GridView1.DataSource = SearchResults1;
GridView1.DataBind();
var SearchResults2 = from u in YourDB.YourUserTable2
orderby u.YourColumn
select u;
GridView2.DataSource = SearchResults2;
GridView2.DataBind();
var SearchResults3 = from u1 in SearchResults2
where !(from u2 in SearchResults1
select u2.YourTablePrimaryKey).Contains(u1.YourTablePrimaryKey)
orderby u1.YourColumn
select u1;
GridView3.DataSource = SearchResults3;
GridView3.DataBind();
You can further elaborate SearchResults 3 if you want like comparing whats in SearchResults1 but not in SearchResults2 and vice versa
