Hi All, i Have made a web application, working fine in WINDOWS and MAC, but in my application i have a file upload option by which, user can select file and upload it on server. For this i use openfiledialog to select files and use filter to filter only allowed file types in selection. the filter is like :

dlg1.filter=Files Allowed(*.pdf;*.doc;*.docx;*.txt;*.xls;*.xlsx;*.ppt;*.pptx;*.bmp;*.jpg;*.jpeg;*.gif;*.tif;*.tiff;*.png)|*.pdf;*.doc;*.docx;*.txt;*.xls*;*.xlsx;*.ppt;*.pptx;*.bmp;*.jpg;*.jpeg;*.gif;*.tif;*.tiff;*.png"

Now it is working fine but in MAC i m unable to pick excel files, excel files not available in allowed types, all though .xls and .xlsx is been added into filter and working for windows. so what changes required in filter for MAC machine. Thanks Yogesh Agarwal

Its fine but i m not so free that i will post the problem without checking it. If u dont know the solution why give this kind of posts.

When i used to upload the excel file, i inserts the records but it used to skip the insertion, like my file has 9000 records it insert 8890 or 8800 sometimes 8950, plz suggest what would be the possible reason.

            Dim conexcel As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("upload/" & FileUpload1.FileName) & "; Extended Properties=Excel 8.0")
            Dim cmd As New OleDbCommand("select \* from \[Sheet1$\]", conexcel)


            Try
                If ConnectionState.Open Then
                    conexcel.Close()
                End If
                conexcel.Open()
                Dim dr As OleDbDataReader
                dr = cmd.ExecuteReader()

                Dim act, cnt, ds, cf, co, distt, dtype As String

                act = ddl\_Activity.SelectedItem.Text.ToString()
                cnt = ddl\_Center.SelectedItem.Text.ToString()
                ds = ddl\_DataSource.SelectedItem.Text.ToString()
                distt = ddl\_Distt.SelectedItem.Text.ToString()
                bcode = UCase(bcode) & "/" & distt & "/" & act & "/" & bno.ToString()
                dtype = ddl\_DataType.SelectedItem.Text.ToString()

                Try
                    Dim name, cnt1, cnt2 As String
                    name = ""
                    cnt1 = ""
                    cnt2 = ""
                    cf = ""
                    co = ""

                    Dim m, p As Int64
                    m = 1
                    While (dr.Read())
                        name = Trim(dr(0).ToString())
                        cnt1 = Trim(dr(1).ToString())
                        cnt2 = Trim(dr(2).ToString())
                        cf = Trim(dr(3).ToString())
                        co = Trim(dr(4).ToString())

                        Dim str As String
                        If cnt1 <> "" Or name <> "" Then
                            str = "insert into tbl\_edu\_dt(full\_name,contact1,contact2,Activity,Center,DistName,DataSource,Collected\_From,Collected\_On,batch\_code,batch\_id,imp\_date,imp\_time,Data\_Type) values ('" & name & "','" & cnt1 & "','" & cnt2 & "','" & act & "','" & cnt & "','" & distt & "','" & ds & "','" & cf & "' , '" & co & "','" & bcode & "','" & m & "','

For now i create the columns with the name 1,2,3,... for loops counter value. and i dont want to bind it with any database table. i used the following code to create the column for now **loop** CheckBoxField cf=new CheckBoxField(); cf.HeaderText=i.toString(); gridview.columns.add(cf) **End Loop** it creates the column for me but no checkbox appears there

But i dont know how much column has to created because no. of columns is dynamic according to the numbers user enters. So how many template field i have to created.

Hi All, i have a textbox with numeric insert so if i worte 5 there, then i need to create a grid with 5 columns with checkboxes. So the column should add at runtime i can't define the template field at designtime, when i user checkboxfield to create checkbox column dynamically then the column created but the checkboxes is not appeared in the column. So what would the solution. plz do reply. Thanks Yogesh Agarwal

sorry for the late reply. But i just did the same.

    t1 = GridView1.Rows(0).FindControl("InstallmentDec")
    t1.Text = dt.Rows(0)(12).ToString()

Its working for me. Here use Foucus function in place of setting text will work fine.
