Not getting value from edit field

[Odeon2084]

Hi everybody,

having tried my utmost to solve the following problem, I'm now very confident in having no idea how to solve it.

I just want to use a combobox in Ajax for setting a filter for a MySQL query. The Filter will be executed by an execute statement, not by the filter function.

As I had no success in using the combobox ItemIndex etc. with ajax, I filled an editfield with the combobox key-value by JS, which was not a big problem.
When now starting the ajax Script via a Button, the function does not recognize the value of the textfield. It does know its value, if I enter the keyvalue manually.

Is there any difference in entering a value by hand or setting the value via JS?

Sources:

PHP Code:

ComboBox1JSChange:

       var cb = document . getElementById("ComboBox1");
       document.getElementById("Edit2").value=document .getElementById("ComboBox1").value;
       //Javascript-Quelltext hier hinzufügen 


PHP Code:

function Button1JSClick($sender, $params)
       {
          echo $this->Button1->ajaxCall("UpdateDbgrid",array(),array("DBGrid1","Edit1"));
       ?>

       //Javascript-Quelltext hier hinzufügen
        return(false);
       <?php

       }
?>

      function UpdateDbgrid($sender,$params)
      {
         //$this->Edit2->Text="fjsdkfj";
         $this->qry_rasterartikel->SQL="SELECT * FROM MB2_RASTER_ARTIKEL WHERE RASTER_ID='".$this->Edit2->text."'";
         $this->qry_rasterartikel->Active=true;
         $this->qry_rasterartikel->refresh();
         $this->Edit1->Text=$this->qry_rasterartikel->SQL;
      }

Thanks for your help!

P.S:
Beeing new to Delphi for PHP programming I would welcome every hint for optimizing my sourcecode.

It's an undocumented feature

When changing edits with js you also must change a hidden field which is really the only thing checked on the server.

findObj('Edit1_hidden').value=new value also;
