if you use the property "AppendDataBoundItems" set to true, you can specify the ListItem in the aspx page. The ListItem taken from the database, will be added below. In this way you can add values that are not present in the database.

ASP.NET

<asp:dropdownlist appenddatabounditems="true" ...="" xmlns:asp="#unknown">
    <asp:listitem text="All" value="" />
</asp:dropdownlist>

<telerik:RadComboBox ID="cmbPortfolio" runat="server" AutoPostBack="True"
AllowCustomText="True"
önselectedindexchanged="cmbPortfolio_SelectedIndexChanged" AppendDataBoundItems="True" >
<items>
<telerik:RadComboBoxItem runat="server" Text="All" Value="100" />

protected void cmbPortfolio_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
{
if (cmbPortfolio.SelectedValue== "100")
{
SqlConnection connections = new SqlConnection(Connection());

SqlCommand commands = new SqlCommand("SELECT costID,costGoal,priority,planned,achieved,costMotivation,costStartDate,costDueDate FROM Cost", connections);

SqlDataAdapter daimagess = new SqlDataAdapter(commands);

DataTable dt = new DataTable();

daimagess.Fill(dt);

gvCost.DataSource = dt;

//gvCost.DataBind();
}

my error
Both DataSource and DataSourceID are defined on 'ctl00'. Remove one definition.

you don't have to rebind gridview with another data in cmbProtfolio_selectedindexchanged evetn. But you must use cmbProtfolio as parameter for datasource binded to gridview
