Hi,

you have missed the Parameter name that was used in your <b>PerformSearch</b> function:

if the PerformSearch looks like

Public static string PerformSearch(string Data)
{
//all your code
}

then use the ajax call like:

$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: 'widgetJosn.asmx/PerformSearch',
data: "{'Data':'"+strInput+"'}",
dataType: "JSON",
success: parseData,
error: AjaxFailed
});

hope this will help.

strInput = strInput +"'strSearch':'"+strSearchType+"'";

this is the my input to webservice.

Public static string PerformSearch(string strInput )
{
//all your code
}

ok, then your ajax call should looks like:

$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: 'widgetJosn.asmx/PerformSearch',
data: "{'strInput':'"+strInput+"'}",
dataType: "JSON",
success: parseData,
error: AjaxFailed
});
