Hello experts..

I have a scenario in my application where end users can send mail to multiple users with seperator ' ; ', they can select from combo items(contact name) or they can enter a new contact's email id. when they enter mail id which is not in the combo list item, i shoud popup the add contact modal popup and once they add it, i will bind the added user and they can select it from combo. so when user sends the mail, i need to get selected contact's contact id and send the mail to those id's

I was able to achieve the above functionality with few issues,
they are
1. when user type a text 'Ra' and combo lists the 'Raja', if user uses keyboard and presses END button and ' ; ', my code assumes it as some text entered other than item frm combo, if user presses 'Ra' and user selects the Raja using mouse and presses ';' means my code works fine.
2. when users enters mail id alone and not entering ';' means, i cant prompt user to add contact.
3. Im storing the contact id in hidden field and when i click send button I'm retrieving it.

I used radcombo, binding its data from web method as follows

<telerik:RadComboBox ID="rdCombotxtToUser" runat="server" Width="397px" Height="140px" Enabled="false"

EmptyMessage="Please enter your contacts (e.g John Doe;Jane Doe)" AllowCustomText="true" AutoCompleteSeparator=";" EnableAutomaticLoadOnDemand="true" EnableItemCaching="true" MarkFirstMatch="true" OnClientKeyPressing="OnClientKeyPressing">

</telerik:RadComboBox>

When users enters ; im firing following below javascript

function OnClientKeyPressing(sender, e)

{

var strSelecteditem

if (e._domEvent.keyCode == "186")

{

var combo = $find("<%= rdCombotxtToUser.ClientID %>");

strSelecteditem = combo._selectedItem;

if (strSelecteditem == null) {

var mdlPopup = $find("mdladdContactPopupBId");

document.getElementById(

"<%=txtName.ClientID %>").value = combo._filterText;

mdlPopup.show();

}

}

Can anyone suggest me any other method or solution to prompt user only when mail id or items not in combo is entered.

Hello Subramanian,

Give a try with following approach:

1) You can check for whether an item is already there in RadComboBox when typing in input box (when pressing Enter). If not found cancel the click event.
Use the findItemByText() method by passing the entered text, if it returns null, means no item with such text.

2) If item is not there with entered text and if it is in e-mail format, then prompt user to add new contact (Use the step.1 technique to check whether item there).

3) Access the corresponding item (using findItemByText method) and get the value of the item to use it.

Hope this suggestion helps.
