[Solved] Strange behavior on selecting an item by clicking and selecting an item by typing

[Adam Plattner]

I was playing the above demo app and found there is different behavior on selecting an item by clicking and selecting an item by typing

When select an item by clicking on it, the selected item will be highlighted and full list is remained. However if select the same item by typing it, the list is limited to the typed one.

My question is how to make the typing behavior is same as the clicking method? Is this default behavior? Is any future release will support this?

Hi Adam,

The behavior of RadComboBox in demo is due to filtering the comboitems with typed text in input field in ItemRequested event. Remove that code and bind the RadComboBox normally and set the AllowCustomText property to True for showing all the items when typing in input field. Checkout the following demo:

Tested this solution and it doesn’t work for us. We have to it working with Load-On-Demand.

Is there any other way?

Hi Adam,

You should not filter the items in ItemsRequested event handler, check the code in the example:

protected void RadComboBox1_ItemsRequested(object o, RadComboBoxItemsRequestedEventArgs e)
    {
        EntityDataSource1.Where = "it.[ContactName] LIKE '" + e.Text + "%'";
        RadComboBox1.DataBind();
    }

please remove the Where clause in order to avoid limiting the items. Also I suggest you set MarkFirstMatch property to true to highlight the items while typing.

Without the where clause, no matter what I typed, it always displays the first page.

I just don't see how this option will work on load demand.

Hi Adam Plattner,

As a comment to your first post, the Load On Demand mechanism of RadComboBox is meant to work just in that way, i.e. when the user types a letter in the input, an incremental search is initiated and only Items matching a certain criteria are loaded and displayed.

In other words, what you are observing is the default, suggested behavior. Of course other logic can be implemented, still it will deviate very little from the main use-case.

Can you please describe in more details the behavior you are trying to implement?
