Hi,
Unfortunately I couldn't replicate the issue at my end. Please have a look into the sample code snippet which works fine at my end.
ASPX:
<telerik:RadComboBox ID="cboBenchmarkCompanies" runat="server" CheckBoxes="true" DataTextField="CountryName" DataValueField="CountryId" />
<telerik:RadButton ID="radbtnCheckedItems" runat="server" Text="CheckedItems" OnClick="radbtnCheckedItems_Click">
</telerik:RadButton>
C#:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataTable data = GetData(new SqlCommand("SELECT CountryName,CountryId FROM Country"));
cboBenchmarkCompanies.DataSource = data; ;
cboBenchmarkCompanies.DataBind();
}
}
protected void radbtnCheckedItems_Click(object sender, EventArgs e)
{
int checkeditemsCount=cboBenchmarkCompanies.CheckedItems.Count;
foreach (Telerik.Web.UI.RadComboBoxItem item in cboBenchmarkCompanies.CheckedItems)
{
//your code
}
}
private static DataTable GetData(SqlCommand selectCommand)
{
selectCommand.Connection = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
SqlDataAdapter adapter = new SqlDataAdapter(selectCommand);
DataTable data = new DataTable();
adapter.Fill(data);
return data;
}
Please provide your full code if it doesn't help.
Thanks,
Shinu.
