    How to automatically add rows from code behind in C1GridView, this is my custom code for asp.net gridview in VB that works fine on button click event
    txtNumberRow.text = number of rows

    Dim RowNumber() As Integer = New Integer((Convert.ToInt32(txtNumberRow.text)) - 1) {}
    Dim i As Integer = 0
    Do While (i < RowNumber.Length)
    RowNumber(i) = (i + 1)
    i = (i + 1)
    C1GridView.DataSource = RowNumber

    c1gridview error:

    Value cannot be null.
    Parameter name: inputString

    Any suggestion?

    please clarify which control you use, C1.Web.UI.Controls.C1GridView or C1.Web.Wijmo.C1GridView? Which version?

    Try binding grid to dynamically created DataTable instead of array:

    Dim dataTable As DataTable = New DataTable()

    For i As Integer = 1 To dataLength

    C1GridView.DataSource = dataTable

    Hi, thanks for replaying, but problem is resolved with existing code, i just added same code with different numbers of created rows, on page_load (number of created rows = 1) and button click event (number of created rows = txtNumberRow.text)
