Hello.
We use RadCombobox with EnableLoadOnDemand="True".
When user type 3 or more characters  in combbox it starts loading data from server. During this action it shows "Loading..." message box. If user press Tab during this action ClientSelectionTextChanged doesn't not fire.

Hello Alexander,

The behaviour that you describe is correct.
The OnClientSelectedIndexChanged fires only if user selects a new item from RadComboBox dropdown.

During items loading - there is no option for the user to select an item.
Additionally item can be selected when user presses the "Enter" key.
Please find more details about the RadComboBox keyboard support at this online demo.

All the best,

Hello Alexander,

The OnClientTextChange event should be fired in case the text in the RadComboBox input has been changed. Please take a look at this help article.
When you press the Tab key - in fact you blur the RadComboBox and move the focus to the next control on the page.
Let me suggest you test how RadComboBox control behaves under different configurations with this online demo.

Here my steps:
1. I am starting typing  in the combobox.
Drop down appears and it has "Loading...." message in it.
I click "Tab" before items are actually loaded.

The result no events are raised. 
Expected result: ClientTextChanged should be raised because I've changed the text and new text is displaying in combobox now.

Hello Alexander,

Thank you for providing us the sample steps.

Can you be more specific about the RadComboBox configuration that you used to reproduce this behavior. Did you managed to observe it with our online demo?

Can you explain your implementation in more details and provide us some sample markup?
We need these details because we want to configure the control in the same way as your combo and to repeat these steps in order to investigate the issue.

All the best,
