ComboBox on a Window

[kaku137]

I want to always display a default value of ComboBox1 on a Window1.

How should I do?

my code:

PHP Code:

function Label1JSClick($sender, $params)
{      
?>
//Add your javascript code here
   Window1.open();    
<?php
}

PHP Code:

function ComboBox1BeforeShow($sender, $params)
{
    $this->ComboBox1->Clear();
    $this->ComboBox1->ItemIndex =2;
    $ds = $this->Datasource1->DataSet;
    $ds->first();
    // iterate through all records and add them
    while (!$ds->EOF)
    {
        // for example use $ds->LAST_NAME to access the fields value
        $this->ComboBox1->AddItem($ds->aaa , null , $ds->bbb);
        $ds->next();
     }
}

You want to display the Item with Index 2 when the Combobox is shown?

After ComboBox1->Clear(), there are no items in the Combobox. Assigning ItemIndex = 2 is not possible at this time, because there is no Item with Index 2 to select.
Do ItemIndex = 2 after your loop, when the Combobox is populated.
