VBA HTML Object Internet Explorer automation - html

Question

How do I select an option from a dropdown menu and update the webpage.
Code:
Dim IE As New SHDocVw.InternetExplorer
Dim HTMLDoc As MSHTML.HTMLDocument
then I navigate to a URL and I fetch the dropdown menu using html id and put value=my desired value
HTMLDoc.getElementById("xyz").Value = "dropdown_option"
I successfully get the option. But, the website doesn't update? e.g. filling up other fields.
I believe some javascript needs to be run.
How can i fix this using VBA?
Source code for dropdown menu field:
<div id="ctl00_MainContent_CreateWebForm__SubjectComboBox_ComboBox" class="Invalid RadComboBox RadComboBox_Telerik SearchComboBox" style="width:206px;white-space:normal;">
<table summary="combobox" style="border-width:0;border-collapse:collapse;width:100%" class="rcbFocused rcbExpanded">
<tbody><tr class="rcbReadOnly">
<td class="rcbInputCell rcbInputCellLeft" style="width:100%;"><input name="ctl00$MainContent$CreateWebForm_$SubjectComboBox$ComboBox" type="text" class="rcbInput radPreventDecorate" id="ctl00_MainContent_CreateWebForm__SubjectComboBox_ComboBox_Input" value="Vælg" readonly="readonly" accesskey="s" autocomplete="off"></td><td class="rcbArrowCell rcbArrowCellRight"><a id="ctl00_MainContent_CreateWebForm__SubjectComboBox_ComboBox_Arrow" style="overflow: hidden;display: block;position: relative;outline: none;">select</a></td>
</tr>
</tbody></table><input id="ctl00_MainContent_CreateWebForm__SubjectComboBox_ComboBox_ClientState" name="ctl00_MainContent_CreateWebForm__SubjectComboBox_ComboBox_ClientState" type="hidden" autocomplete="off">
</div>
Source code for dropdown options:

Answer 1

For anyone stuck with this issue. I solved this by finding focus property of getelementbyid method. Like this:
First I loop over the list to find my option. I use tagname and classname and matching the innertext property = myoption (This is only necessary if the field doesn't allow you to input text) Then when match occurs, perform .focus followed by .click on that object.
Otherwise just use focus followed by click property on the field and enter your option:
HTMLDoc.getElementById("xyz").focus
HTMLDoc.getElementById("xyz").click
HTMLDoc.getElementById("xyz").Value = myoption
This will automatically refresh the html page.
This solved my issues.
