Hello Everyone,

Please tell me how to set the ContextKey of AutoCompleteExtender, i am tried but it will shows me a Error like this.

Compiler Error Message: CS0103: The name 'AutoCmpExt' does not exist in the current context

Source Error:


Line 453:         setContext = function ($this) {
Line 454:            $bdsType = $j($this).parents('tr').children('td:eq(6)').find('select').val();
Line 455:            $find('<%=AutoCmpExt.ClientID %>').set_contextKey($bdsType);
Line 456:         }
Line 457:      });

i used the Javascript to set ContextKey of AutoCompelteExtender like this.

$j(document).ready(function () {
         setContext = function ($this) {
            $bdsType = $j($this).parents('tr').children('td:eq(6)').find('select').val();
            $find('<%=AutoCmpExt.ClientID %>').set_contextKey($bdsType);
         }
      });

i used the AutoCompleteExtender inside the GridView. When i type in the textbox, the jquery code will find the 'select' Control on previous cell of the GridView and the selected value of that control as a ContextKey of AutoCompleteExtender. the GridView Source i provided the below.
