I know how to use
Invokemember("Click")
to simulate clicking in web browser. But I cant find the c# code for simulating the selection and then clicking an option from a combo box in a specific URL.
The selection can be done by:
webBrowser1.Document.GetElementById("id").SetAttribute("value","option");
but this only changes the text of the combo box in the web page. It does not update the page based on the selected option in the combo box. And again
Invokemember("Click")
does not do anything in this case.
Thanks in advance.

Page A has a dropdownlist of shipping methods.
User makes a selection and clicks next.
Page B allows them to change their shipping address, which changes their shipping methods.
User clicks back button.
Page A shows new shipping methods in drop down, but Chrome has added a blank option at the top and made it the selected option. This blank option DOES NOT EXIST in the view source.
Chrome is choosing to insert a phantom blank selection item when its persisted drop down list value no longer exists, rather than respecting the selected="selected" tagged option.
This causes .net event validation to fail whenever the user tries to interact with the form, because this blank selection isn't real. "Invalid postback or callback argument. Event validation is enabled"
I've tried form.reset() on page load, and turning autocomplete off on the form tag. Anyone have any ideas? Much appreciated.
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.
This is more of a UI Design approach on how to let the user edit values in a list box.
I am interested in the Usability issue.
First approach is having a textBox near the list.
When user selects an element in the list, the text goes to the textbox.
My second though is having an input box coming up (a modal) and edit the value there.
Another option is to use a list view and let the user edit inline. This might be tricky if the user doesn't know this is editable (not all user do)
What would you prefer? Any suggestions on a different approach?
I have used data binding to bind text boxes and numeric controls to a listbox. As the list box selection is changed then the relevant data appears in the controls.
Another way is a property grid linked to the current selected item in the list box. That works well for users who may be relatively savvy for the property grid.
As far as I think I would go for your second approach. I would like an edit button. When I select any item in the list box, edit button should be enabled. When I click edit a small modal dialog saying ok or cancel and in textbox displaying the current value which I can edit.
I think a list view looks a lot cleaner, and people are getting more used to this kind of thing as more web pages use client-side script, Ajax, etc.
I don't like the idea of a modal popup - very clunky.
I did this recently using a hidden text box that I would show positioned over the list box item populated with the selected item text when the user double clicked or pressed F2. When the user pressed enter or the text box lost focus, the text box was hidden and the list box item text was replaced with the edit box text. If the user pressed escape, the text box was hidden and the list item text remained unchanged (i.e cancel).
I have an application where I have a product search text field. To implement a predictive text like feature, I hid a combo box behind the text box that populates with the appropriate products. That all works fine and dandy. The problem is the cursor does not show on the form while the combo box is dropped. I can still use the cursor to select the results from the combo box, but it is invisible until I click something on the form.
ComboBox AutoComplete Custom Capabilities
See this accepted answer to this question. Combo box already has an AutoComplete mode. No reason to hide it behind a textbox.
Bring the cursor back with:
Cursor.Current = Cursors.Default;
Do you have the combobox dropdown style as DropDownList?
Also why not use the AutoComplete Mode to accomplish predictive text feature

I am contemplating having a menu in my WPF application that works in a similar way to the Windows 7 start menu.
In my mind, this means that I should make a user control that consitues a button. Clicking on the button will display a list box, and inside the list box it will be possible to search the items that are registered in the list box.
Would that be an advisable way of doing it or is it better to do something different such as changing the template of a menu control?
Thanks for any help, it is very much appreciated.
It seems you have the design already made up. Do exactly that! :) Create a button that when pressed, displays a panel that contains a list box and a text box. Tie an event to key presses in the text box that changes what the object bound to the list contains.
After that, it's just a SMOP!
