Add temp rows to RadGrid

[Carlos]

Hi im trying to do something and i cant find they way to do it...
Here is what i want to do...
I have a RadComboBox filled with a datasource and i want to have a button to add what i have selected in the RCB to a temp Radgrid (i got to be able to add as rows as i need from the same RCB) plus i need to be added an editable checkbox column for each row...
i dont want to save anything to database. i just need this radgrid to display the info. My codebehind is VB

Hope someone can help me... and Thanks!

Carlos.

Hi Carlos,

To achieve the desired functionality you could try keeping a temporary DataTable into the Session and bind the RadGrid to it:

Public Property MyDataTable() As DataTable
        Get
            If Session("MyDataTable") Is Nothing Then
                Session("MyDataTable") = New DataTable()
            End If
            Return CType(Session("MyDataTable"), DataTable)
        End Get

        Set(ByVal Value As DataTable)
            Session("MyDataTable") = Value
        End Set

    End Property

Protected Sub RadGrid1_NeedDataSource(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource
        RadGrid1.DataSource = MyDataTable
End Sub

When the user clicks add button you could add new row into the table and rebind the RadGrid:

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        If MyDataTable.Columns.Count = 0 Then
            MyDataTable.Columns.Add("ProductName")
        End If

        Dim selectedvalue As String = RadComboBox2.SelectedItem.Text
        MyDataTable.Rows.Add(selectedvalue)
        RadGrid1.Rebind()
    End Sub

Additionally I am sending you a simple example. Please check it out and let me know if it helps you.
Looking forward for your reply.

All the best,
