Unable to select data from combo box using CodedUI

I am using CodedUI technology to do the automation.I have a combo box control and a grid inside as an item. I can find the combo box and managed to open the grid as shown in Fig (01) Control with properties. Now,for further testing I need to click on row item inside the grid.
Issue : I couldn't find the grid and failed to navigate using the search properties. As you see in Fig (01) , the parent level is in desktop client and not bound to our application. Even though the grid belongs to the combo box visually, still it is not listed either parent or the application window.
Solution required: I need to select/click on row item in the grid using hand coded coded ui.
Code Snippet
Note : Playback control also failed to do the desire output.Clicking on the row based on mouse co-ordinates is not much appreciated.
Looking for the solution and thanks much in advance.

Try identifying the grid/Table with combobox as a parent instead of your main application.Something like this
if cboName is your combobox then
HtmlTable tbldata = new HtmlTable(cboName);
Provide any of the columnheaders or one of the Search Property to identify it.
Hope it helps

Hope you must have tried highlighting the grid and checked the parent.
Just try to do record and play u r case and generate code .And see code is getting generated ,how it is maintaing child parent relationship.Than u will get some idea and parameterized the thing in your code

Radio Boxes Clickable Images

I am trying to figure out how I would setup a group of images to work like radio buttons. Basically when a user clicks a image it wil display a check mark below to indicate it has been selected. I could accomplish showing the check mark I believe by a onclick event and some css. But what would be the best way to do this with ASP.net I also need to transmit the data to the server via a form.

I would populate a hidden field with the resulting value of the selection via client-side code. Then you just read that value in your code behind on submit.

I need to change Multiview or place holder whenever I select different values in dropdown list

I am creating online booking page.
I got some example page you can see in this link
http://www.parkercorporate.co.uk/webbookercc/OneForm.asp
I need the same behaviour in my site whenever user selects value in pickup dropdown list in the right side I need to change the text values or view.
To do this behaviour how should I write code in ASP.NET and c#.
Thanks

First, use an UpdatePanel so you don't see any visual postback.
Second, set the AutoPostBack property on your DropDownList to True.
Third, handle the DropDownList's SelectedIndexChanged event. This will now fire after every change in the DropDownList, because you enabled AutoPostBack.
In the event handler, you can now change the ActiveViewIndex of the MultiView, or show/hide controls, change textboxes, etc.

First, create different blocks (i.e divs) and give ID's to them.
Then, for each value in the dropbox, fill the divs w.r.t it.
Assign "OnChange" event to the dropdown, and in the handler, set visible or invisible to corresponding block.
On the other hand, If you want to do this on client side, I strongly suggest you to use JQuery, to prevent a lot of requests going to server.
Check this out with JQuery:
make visible div on dropdown select in jquery

If you won't fetch values from database, there is nothing complex about this page. Because it just writes hospital if you choose hospital etc. and changes control's visible state.
Even if you think you need db queries when dropdown's selected change event, actually at this page there is no need. Just store db values in hidden controls (like Hospital- for Hospital) and when dropdown selection changes, write hidden's value completely in javascript

Paged Custom ComboBox

I would like to have some sample code on how to do a paginated ComboBox.
My data consist on 1300+ items. When the user clicks the combo box arrow, the combobox will display display 25 (page size configurable) items at the time with arrows up/down (depending on page location) so that the user can request the previous/next page.
The data is coming from a generic list.(List)
Thus, the idea is to display only a subset of the data at the time.The user can scroll and select from the list as per normal combobox. At the top and bottom of the list should be a new button to request the previous or next page of navigator values.
Note: All data is read only. For legacy issues I can only use Winforms (.net 2.0) and C# but VB.net code will do as well

you might want to consider using a treeview as a dropdown control for your combobox, smth like is done here:
you can get source code for this control here: ComboBox control with a TreeView I guess it should give an idea on how to proceed with your task

Binding a treeview Dynamically and getting selected nodes

I am trying to dynamically (i.e. via code) bind a directory to a asp.net Treeview control and once the data is bound and displayed to the user i want to get a list of nodes the select.
I have got the binding and displaying of checkboxes to work fine , but when i query the Treeview1.CheckedNodes it always returns 0. If i do not bind dynamically but created the nodes by hand then it is able to get the selected nodes.
Thanks

My guess is ... since you're dynamically building the whole thing from scratch every page load you're losing the selection.
You need to somehow store info about which checkboxes are checked before the post back (in Viewstate or Session or whatever depending on your needs) and then re-apply those selection to your tree after rebuilding it (on page load or preload if you store it in Viewstate).
