Finding and Selecting an item

Chris Drew posted over 13 years ago

I'm sure that this is a basic function of a dropdownlist but I am finding the CSOM very difficult to get to grips with but they may be down to my lack of knowledge of JavaScript/Ajax but there does seem to be a major lack of any clear documentation or samples.

I have a WebDialogWindow which contains a WebDropDown which is databound. I click a button on a grid to view the item on the grid using the WDW. What I want to do is to recover a text field (Name) from a column in the Grid (which I have done) and pre-select this name in the WebDropDown. Pretty standard stuff...

My code so far from lots of various posts is:-

var oddlpersonnel = $find('<%=ddlPersonnel.ClientID %>');

var holderName = gridrow.get_cell(1).get_value();

oddlpersonnel.selectItem(holderName,

true, true );

Looks correct to me - I also tried set_selectItem just in case I needed the extra set_ but still no luck. The web page says the object does not support this property or method. I'm not sure I can call selectItem in this way (passing a string which is the displayed text in the DDL) but this doesn't work anyway.

Any suggestions please before I just revert to a standard asp:DropDownList

Hello cmdrew,
you can use the following javascript to find and select item:


 var ddl = $find('<%=WebDropDown1.ClientID %>');

            //iterate through WebDropDown items
            for (i = 1; i < ddl.get_items().getLength(); i++) {
                var item = ddl.get_items().getItem(i);

                //Check if the item has text equal to "Beverages"
                //You can use item.get_value() to check values
                if (item.get_text() == "Beverages") {
                    //select item
                    item.select();
                }
            }

I hope that this helps
