Hi Nikolay,

I have tried using ClientIDMode="Static" like this:

<ig:WebDropDown ID="dropdown" runat="server" ClientIDMode="Static">

</ig:WebDropDown>

After this, I tried using $find("dropdown") and also #find("<%=this.dropdown.clientID%>") but both are returing NULL value and not the object.  What may be the issue?

Note: I am using ClientIDMode as "AutoID" in web.config file and I am not looking for a  solution to make ClientIDMode changes in web.config.

Hi, Sunil Mehta.

The right method for you is not get_currentValue() but get_selectedItemIndex(). To get the value, use:

Thanks Nikolay. We are very near to closure now. Here is another issue.

I have a function that fills a combobox with values based upon the value changed in another combobox control.
The below function does that requirement:

function FillCombobox(Code,strValue) {
var NextCombo;
var appPath;
var getFile;
var countall;
appPath = location.href;
getFile = appPath.split("/");
countall = getFile.length - 1;
appPath = appPath.replace(getFile[countall], "FillSubCombo.aspx");

 if (strValue !='') {
  var oXMLHTTP = new ActiveXObject( "Microsoft.XMLHTTP" );
  var sURL = appPath + '?Code=' + Code + '&Value='  + strValue;
  oXMLHTTP.open( "POST", sURL, false );
  oXMLHTTP.send();
  if(oXMLHTTP.responseText!=''){

  if (document.all.combobox.popup.length > 0)
   { var combolen = document.all.combobox.popup.length;
   for (var j=(combolen - 1); j >= 0 ; j--)
    { document.all.combobox.popup.options[j] = null;
    }
   }
   var opt0 = new Option("","");
   document.all.combobox.popup.options[document.all.combobox.popup.length] = opt0;
   var sXMLReturn=oXMLHTTP.responseText;
   var MList = sXMLReturn.split('^');
   for (var i=0; i < MList.length;i++)
   {
    var SList = MList[i].split('~');
    var opt = new Option(SList[0],SList[1]);
    document.all.combobox.popup.options[document.all.combobox.popup.length] = opt;
   }
   document.all.combobox.popup.item(0).selected = true;
   document.all.combobox.popup.textfield.value = document.all.combobox.popup.item(0).text;
  }
  else
  {
   var opt0 = new Option("","");
   document.all.combobox.popup.length=0;
   document.all.combobox.popup.options[NextCombo.length] = opt0;
   document.all.combobox.popup.item(0).selected = true;
   document.all.combobox.popup.textfield.value = document.all.combobox.popup.item(0).text;
  }
 }
 else
 {
  document.all.combobox.popup.item(0).selected = true;
  document.all.combobox.popup.textfield.value = document.all.combobox.popup.item(0).text;
 }   
}

Currently, the combobox that I am using in my application uses the below code snippet:
document.all.combobox.popup.options
Do we have any property/method in the webdropdown with the same functionality as options? I want to replace
the above lines in Bold with the code snippet for infragistics webdropdown.

Hi Nikolay,

Here is the explanation as what is happening in the above function. We would like to achieve the same functionality with the webdropdown.

There are 2 categories of webdropdown we have, one is a group webdropdown with values like 0100, 0200, 0300, 0400 and so on. All these values are retrieved from tables. Other is a sub webdropdown which loads value based upon the value in the group webdropdown. For example, if 0100 is being selected in group webdropdown, then the sub webdropdown will load all items starting with "01" and not any other values. Similarly for "0200", all values starting with "02". These values are also being retrieved from tables and sent to javascript under "oXMLHTTP.responseText". This object includes all the values to be loaded into sub webdropdown based upon the value selected in group webdropdown.

Now where I am getting the problem is: how to load these values into the sub webdropdown.

1. If (oXMLHTTP.responseText !='') // means sub webdropdown values have been fetched from tables

then, load all these values in the sub webdropdown.  // We would like to know how to achieve this.

if 10 values have to be loaded in the sub webdropdown, then the cursor should be on the first one. The, from the 10 values, user can select any value if required.

2. If (oXMLHTTP.responseText = '') // means no values have been fetched from the tables.

then sub webdropdown should be empty.   // We would like to know how to achieve this.

This entire functionality will be executed when the value in the group webdropdown changes. We are calling a function that executes these functionality on "valueChanged" client-side event of group webdropdown.

Thanks,

Sunil Mehta.

Hi, Sunil Mehta.

If it's not a problem for you, please create different forum thread for this issue. It's because the last problem is different from the title and idea of the current forum thread and it such cases is better to separate them.

Thank you

Nikolay

Hi,

Is there a way to set the current display text and value of a webdropdown in the server-side(code behind vb file)?

Thanks,

Sunil Mehta.

Nikolay, Please do the needful for #1, #2 and #5.

Thanks,

Sunil Mehta.
