Hi Maya. I have applied his example, but it is for an actual dropdown control, not the dropdown inside the webdatechooser. Below is what I have, but of course I get an object expected error because the webdatechooser is not a dropdown/combo control and I'm not sure how to address it. Thanks.

function igMyGrid_BeforeRowTemplateCloseHandler(gridName, rowId, bSaveChanges) {
    var grid = igtbl_getGridById(gridName);
    var combo = igcmbo_getComboById("<%= igMyGridDueDate.ClientID %>");
    var localEvent = (typeof (event) != 'undefined') ? event : grid.event;
    var localSrcElem = localEvent.srcElement ? localEvent.srcElement : localEvent.target;

    if (localEvent && localSrcElem && igtbl_contains(combo.container, localSrcElem))
        return true;
} 

Maya, have you gotten chance to look at this(see previous comment)? Please help! Thanks so much.

Hi Maya. Please Help!!! I'm including the code and javascript. For some reason, my WebDateChoosers are once again getting the date from the last row of my UltraWebGrid when I edit/save, not the current edit row. I've stepped through the code and the javascript portion sets it correctly before the template opens. When I edit text or something besides the webdate chooser and save, it doesn't keep that set value of the webdate chooser, it picks up the date of the last row in the grid. I'm not sure what I muffed up, but would you take a look and see what it is? Here is a scenario

Due Date  Description            Status   Analysis            Completed Date
--------- ---------------------- -------- ------------------- --------------
8/30/2011 Some text in a textbox Open     Some more text here 4/15/2010
3/15/2012 Some text in a textbox Open     Some more text here 2/5/2011
3/25/2012 Some text in a textbox Open     Some more text here 1/12/2011

If I edit row 1, change the description and maybe the Status and save, it doesn't save the dates as 8/30/2011 & 4/15/2010, it saves row 3 dates 3/25/2012 & 1/12/2011. This is on a content page of a masterpage. The grid is inside an ajax updatepanel.

function igMyGrid_BeforeRowTemplateOpenHandler(gridName, rowId, templateId) {
    var row = igtbl_getRowById(rowId);
    var currentValueDueDate = row.getCell(1).getValue();
    var currentValueCompletedDate = row.getCell(6).getValue();
    var dueDate = new Date();
    var completedDate = new Date;
    var compareDate = new Date;
    compareDate = dateFormat("1/1/2000", "mm/dd/yyyy");
    dueDate = dateFormat(currentValueDueDate, "mm/dd/yyyy");
    completedDate = dateFormat(currentValueCompletedDate, "mm/dd/yyyy");
    currentValueDueDate = dateFormat(currentValueDueDate, "mm/dd/yyyy");
    currentValueCompletedDate = dateFormat(currentValueCompletedDate, "mm/dd/yyyy");
    if (dueDate > compareDate) {
        dateChooserMyGridDueDate.value = currentValueDueDate;
        dateChooserMyGridDueDate.inputBox.value = currentValueDueDate;
    }
    else {
        dateChooserMyGridDueDate.value = Date();
       dateChooserMyGridDueDate.inputBox.value = "Select a Date";
    }
    if (completedDate > compareDate) {
        dateChooserMyGridCompletedDate.value = currentValueCompletedDate;
        dateChooserMyGridCompletedDate.inputBox.value = currentValueCompletedDate;
    }
    else {
        dateChooserMyGridCompletedDate.value = Date();
        dateChooserMyGridCompletedDate.inputBox.value = "Select a Date";
    }
}
function igMyGrid_BeforeRowTemplateCloseHandler(gridName, rowId, bSaveChanges) {
    var grid = igtbl_getGridById(gridName);
    var combo1 = dateChooserMyGridDueDate; 
    var combo2 = dateChooserMyGridCompletedDate;
    var localEvent = (typeof (event) != "undefined") ? event : grid.event;
    var localSrcElem = localEvent.srcElement ? localEvent.srcElement : localEvent.target;
    if (localEvent && localSrcElem && igtbl_contains(combo1.container, localSrcElem)) {
        return true;
    }
    if (localEvent && localSrcElem && igtbl_contains(combo2.container, localSrcElem)) {
        return true;
    }
}
function igMyGridDueDate_InitializeDateChooser(oDateChooser) {
    dateChooserMyGridDueDate = oDateChooser;
}
function igMyGridCompletedDate_InitializeDateChooser(oDateChooser) {
    dateChooserMyGridCompletedDate = oDateChooser;

Hi Maya, I got this to work. I was getting an object required error using

var combo = igcombo_getComboById("<%=igMyGridDueDate.ClientID %>");

But since we have already intialized the WebDateChooser globally in previous examples, I changed it to

var combo = dateChooserMyGridDueDate;

and it worked as expected. Thanks so much Maya, you are a great resource and you are greatly appreciated!!!
