ComboBox in Repeater - javascript

[jgig]

I have 2 ComboBoxes in a repeater and I need to set the javascript value in the second row with the reverse of the first row.

Repeater-
Row 1 - ComboBox_BEGIN, ComboBox_END, ...other controls
Row 2 - ComboBox_BEGIN, ComboBox_END, ...other controls

after the user selects a ComboBox_BEGIN value in row 1 I want to via javascript set the value in row 2 ComboBox_END. all the samples Ive seen that are showing this arent using a repeater so its a bit unclear. I was trying to set this up in the PreRender of the repeater, adding an onblur of the Row 1 - ComboBox_BEGIN. I have that code ready but when I add it, it adds it to the outer div the control renders and not the child textbox.

Can someone send me a link or a code sample that shows some similar functionality so I can understand how to do this. (if it matters these ComboBoxes are Loaded on Demand also)

So basically this is what Im trying to do on PreRender:
 

foreach

 

(RepeaterItem item in rpt.Items)

 

 

{

 

 

RadComboBox rcbBegin = (RadComboBox)item.FindControl("Beginrcb");

rcbBegin.Attributes.Add(

"onblur", string.Format("somefunction('{0}', '{1}');", rcbBegin.ClientID, rcbAnother.ClientID));

//the ONBLUR never fires because it is placed on the <div tag that holds all of the RadComboBox once Rendered

}

I can do the rest if I can just pass the 2 different Client IDs im looking for

Hello jgig,

You can do the following:

1. Add a custom attribute - NextComboID to your comboboxes:

foreach (RepeaterItem item in rpt.Items)
{
  RadComboBox rcbBegin = (RadComboBox)item.FindControl("Beginrcb");
  rcbBegin.Attributes["NextComboID"] = rcbAnother.ClientID;
}

2. Subscribe to the OnClientBlur event and focus to the next combobox:

function onBlurHandler(sender, eventArgs)
{
    var nextComboID = sender.get_attributes().getAttribute("NextComboID");
    var nextCombo = $find(nextComboID);
    if (nextCombo)
    {
        var input = nextCombo.get_inputDomElement();
        input.focus();
    }
}

I hope this helps.
