I am populating a combobox dropdown with node fields from an Xml document. I have that working. Now I have the text in the dropdown menu of the combobox. I want to be able to press a 'Go' button and use the selected text. What are the commands please?
Have a look at the SelectedText property of ComboBox. It will return a string containing the currently selected text (ie. the text of the currently selected item) of the combo box.
To handle this from a button press, add an OnClick event handler to the button, and in this event handler get the SelectedText and do what you need with it.
During events, cboMyCombo.SelectedText may be null because its value has been cleared: "For example, if you retrieve the SelectedText value in a button Click event handler, the value will be an empty string." read here.
You may just want to try using cboMyCombo.Text

I have a ComboBox in a DataGridTemplateColumn.CellTemplate. When editing an existing entry the UpdateSourceTrigger=PropertyChanged fires on property change. However, I want it to fire on a new line as well just as if I have press (clicked) in any of the cell to start new entry.
By the way I am not using DataGridTemplateColumn.CellEditingTemplate for editing but DataGridTemplateColumn.CellTemplate which I thinks looks better unlike the default
In MS documentation it says DataGridCell.Selected Event Occurs when the cell is selected. That means when one presses a KeyDown or mouse click in the cell. I guess what I want is how to select a cell through a ComboxBox selection changed event. I want when I select a record in the combobox to begin the a new line just as if I have started typing soemthin in any of the DataGrid cells.
I have a VB6 application that has been running for quite sometime. Currently I'm trying to update one of the form that has a combobox 2.0. Because the combobox is populated with hundreds of items - I'm trying to update it so that users are able to click on a look up button next to it, where another window opens up with all the items from the combobox. User will be able to search by keyword and/or select an item and double click on it and have it appear in the combobox. The issue I'm having is with trying to pass no value or "" when CANCEL is clicked. I'm able to pass the value if I in the properties window my STYLE Is set to COMBO rather than list. However, the issue I come across is that with COMBO the value (text) in the combobox sometimes is not aligned properly. Is there a way to pass a "" value to a combobox 2.0 without changing the style to COMBO?
If they hit cancel set the ListIndex of your combo to -1 rather than setting the text property. This is the value for no item being selected.

What event handler to use for ComboBox Item Selected (Selected Item not necessarily changed)
I am using Infragistics UltraComobEditor to show some values by filling it's ValueList property with items. The selected item is just like a template and it require to update all elements which are using that template.

I have a kendo combobox
#(Html.Kendo().ComboBox()
.Name("ddSystems")
.Filter("contains")
.Placeholder("-- Select --")
.BindTo((IEnumerable<SelectListItem>)ViewBag.systemList)
)
Onchange, a textbox is loaded in ajax. A submit button posts the textbox value and combobox value to the controller. When I get back to the view, I need ddSystems to be reset to empty. I used
$('#ddSystems').data('kendoComboBox').value(null)
and
$('#ddSystems').data('kendoComboBox').text('')
but it always retains the previously selected value. Since I use ajax, this will not display the textbox and I am stuck. Please help.
This will clear the combo box and disable it
Google is your best friend....
var combobox = $("#comboBox").data("kendoComboBox");
combobox.value();
combobox.enable(false);
I need the following behavior for WPF Combobox:
i need autofilter in combobox. Took the implementation from here. But when there are several items in dropdown that are almost same-when i press DOWN it just selects the first one from list and hides others(see video of current behavior here: http://www.youtube.com/watch?v=_WYAgMTxc4M). If i want the second possible-i have to select it with mouse or write down the whole item display name in editable part of combobox. Is it possible to select item without changing editable part of the combobox, until i press ENTER, for example?
I think that problem is when you select the item, it fill the text area of ComboBox, than it notify that filter text changed and it applied new filter for the list, and the only one item remains in the list.
You should to rewrite this behavior that will apply filter only if KeyPressed / KeyDown / KeyUp events was fired.
