I have 3 asp.net dropdownlist and 1 Button

dropdownlist1=(project number)

dropdownlist2=(project title)

button =(add)

(for your info : I call the value of dropdown from list in Sharepoint2010)

I selected project number,
then I select title then activity...
press add button then all value displayed in gridview.

The problem is ,when data was insert to gridview row, it will stretch the gridview down not in html table row by row.

How to inserted it row by row in html table?

Follow this example:

VB

Protected Sub btnSaveEmail_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSaveEmail.Click
        dt_email = Session("dt_email") 'OR Dim dt_email As New DataTable

        Dim dr As DataRow
        dr = dt_email.NewRow()

        dr("intCodigoClienteEmail") = Cint(DropDownList.Selectedvalue)
        dr("intCodigoCliente") = Cint(DropDownList.Selectedvalue)
        dr("vchEmail") = Cint(DropDownList.Selectedvalue)

        dt_email.Rows.Add(dr)

        grdEmail.DataSource = dt_email
        grdEmail.DataBind()

        Session("dt_email") = dt_email
    End Sub

First you take a datatable existing OR can create a new one, then create a datatable DataRow this by adding a line as the selected values.
After all done, load the datatable with the datarow.
After that load the grid with datatable

I think the cleanest way to do this would be to click on the include in a Temporary table and then climb her data to the Grid

Try cascading dropdowns -
