Parameters for WebServiceSettings Method

[Mickael]

Hi,
I am adding RadAutoCompleteBox dynamically to my page.
The autocompleteboxes are using a PageMethod to get the results for the dropdown.
Each autocompletebox is related to a different type, but I cannot implement a search function for each type because these are dynamic too.
I know the Type-autocompletebox relation, but I cannot differentiate them in the PageMethod.
Is there a way to pass a parameter to the PageMethod through the WebServiceSettings of the AutoCompleteBox ?

I tried to use the OnClientDropDownOpening client event, but it is fired after the search completed, so it is too late already.

Hello Mickael,

You could use the OnClientRequesting client-side event of the RadAutoCompleteBox, in order to use the context and pass any custom parameters to the WebMethod. Please consider the below implementation :

javascript

<script type="text/javascript">
       function OnClientRequesting(sender, args) {
           var context = args.get_context()
           context["CustomParam"] = "CutomValue";
       }
   </script>

code-behind

[WebMethod]
   public static AutoCompleteBoxData GetCompanyNames(RadAutoCompleteContext context)
   {
       string CustomParamValue = context["CustomParam"].ToString();

I am trying to use the OnClientRequesting, but it looks like I am doing something wrong because it is not firing
This is what I have so far:

_autoCompleteBox = new RadAutoCompleteBox();
_autoCompleteBox.ID = String.Format("Extra_RdtCmpltBx_{0}_{1}", TypeData.Name, ID);
_autoCompleteBox.Filter = RadAutoCompleteFilter.StartsWith;
_autoCompleteBox.DropDownPosition = RadAutoCompleteDropDownPosition.Automatic;
_autoCompleteBox.AllowCustomEntry = true;
_autoCompleteBox.InputType = RadAutoCompleteInputType.Text;
_autoCompleteBox.OnClientRequesting = "OnClientRequesting";
_autoCompleteBox.WebServiceSettings.Method = "GetResultsByType";
_autoCompleteBox.WebServiceSettings.Path = "Popup_Add.aspx";
_autoCompleteBox.TextSettings.SelectionMode = RadAutoCompleteSelectionMode.Single;
_autoCompleteBox.Entries.Add(new AutoCompleteBoxEntry(Name));

function OnClientRequesting(sender, args) {
    debugger;
    var context = args.get_context()
    context["CustomParam"] = "CutomValue";
}

[WebMethod]
public static AutoCompleteBoxData GetResultsByType(RadAutoCompleteContext context)
{
    string searchString = context["Text"].ToString();

    string CustomParamValue = context["CustomParam"].ToString();
}

Hello Mickael,

I have created a runnable sample for you, demonstrating the implementation of the previous suggested approach. You can give it a try at your end and let us know if the issue still persist.

Note : dll files are removed from the attachment.
