Hi,

I need to loop through every row in a multicolumn dropdown in client side, how can this be acheived?

Scenario. There is a multicolumn radcombobox whith 3 columns, User enter a value in a textbox which should get added to the multicolumn racombo. Before inserting the value to the combo I need to check if that value which user has entered is already present in the list or not. If the value is there in the list already I need to display a error message to the user. I need this to be acheived client side. I need to loop through every row in the item list and get the value of the first column.

Please let me know how can  this be accomplished.

Hi,

I just implemented the below logic and it worked. Please review this and let me know if this solution is okay, I checked in IE and Firefox and it worked fine.

 

 

 

function ValidateForDuplicate()
  
{
  
var combo = $find('<%= RadComboBox1.ClientID %>');
  
var newAccNum = document.getElementById('accNumber').value;
  
for (var i = 0; i < combo.get_items()._array.length; i++) 
  
  
var ctrl = combo.get_items().getItem(i);
  
if(ctrl != null ) 
  
{
  
  
var b = ctrl.get_attributes().getAttribute("DebitAccountNumber");
  
alert(b);
  
}
  
}
  
return false;
  
}

I am setting the attributes in the ItemDataBound event.

Hello Neema,

The javascript function seems ok, you can only change this  - "combo.get_items()._array.length"  to "combo.get_items().get_count()".
