Did you tried FileUpload control??

It will help you upload the file and then also give you its path, you can then save the path in database.

You need to enable checkbox.right?

try this in javascript,

Findout CheckBox as chk by getElementById and then,

chk.disabled = false;
chk.parentNode.disabled = false;

Let me know if any pblm is there.

That event calendar control should have some databinding event?

You can handle that event and then use it to add controls to it.

Help with Crystal Reports [modified]

Hi. I'm rather new to asp.net and even more so in crystal. Basically this is the first time I'm using this. What I need to do is prepare a report from a dynamically created dataset(untyped if you will). I have read a lot of articles online but haven't been able to make it work.
Basically the table that i want to display in crystal doesn't exist in database and was created programmatically as a DataTable

The data simply doesn't display.Here's the code in codebehind:

Protected Sub CrystalReportViewer1_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles CrystalReportViewer1.Init
Dim rpt As New ReportDocument
rpt.Load(Server.MapPath("CrystalReport1.rpt")
rpt.SetDataSource(dset.Tables("Tab1"))
CrystalReportViewer1.ReportSource = rpt
CrystalReportViewer1.DataBind()
End Sub

Please note that the dataset is populated correctly as i can see it in a gridview. CrystalReport1.rpt uses the same schema as Tab1 but using a dataset included at design time called "DataSet1".
Here is the code for how this dataset was created:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Try
Dim mysqlDad As MySqlDataAdapter
Dim mysqlConn As MySqlConnection
Dim query As String = "" 'some select query that returns 2 rows.
Dim connstring As String = "Database=ocsweb;Data Source=10.135.158.160;User Id=abc;Password=abc"
dset = New DataSet("Home")
dset.ReadXmlSchema(Server.MapPath("~\App_Code\DataSet1.xsd"))
mysqlConn = New MySqlConnection(connstring)
mysqlDad = New MySqlDataAdapter(query, mysqlConn)
mysqlDad.Fill(dset, "Tab1_tmp")
Dim Dt As New DataTable("Tab1")
Dim col1 As New DataColumn("Unchecked")
Dim col2 As New DataColumn("Checked")
Dt.Columns.Add(col1)
Dt.Columns.Add(col2)
Dim dr As DataRow = Dt.NewRow()
dr.Item(0) = dset.Tables("Tab1_tmp").Rows(0).Item(0)
dr.Item(1) = dset.Tables("Tab1_tmp").Rows(1).Item(0)
Dt.Rows.Add(dr)
dset.Tables.Add(Dt)
catch ex as exception
msgbox(ex.message)
end try

If there is something else that can/needs to be done, please let me know. I'm very new and could surely use some help here. Frown | :(

Try with button click event instead of pageload to bind the dataset to report and see
