[Solved] Combo Box losing focus

[Pawan Kohli]

Hi everyone,

Here is the scenario I am having an issue with:

I have two Combo boxes on my webpage, combo box A refreshes combo box B after you move off combo box A. In the code behind for combo box A selected index change is  

RadScriptManager1.SetFocus(COMBOBOXB.ClientID +

"_Input");

However this code does not properly set focus back on the control. The list item that is combo box is not given the blue selection.

Please advise.

Thank you in advance.

Hi Pawan Kohli,

Please make sure that the second combo (COMBOBOXB) has AllowCustomText="True" (or MarkFirstMatch="True")
This is needed so the control can receive the focus.

Hello Veselin,

Thank you for your response. The control is recieving focus; however the text within the drop down is not selected(meaning the text is not highlighted blue).

Please advise.

Hi Pawan Kohli,

That code will put the cursor to the input area, but will not highlight the text. To highlight the text please use this approach:

protected void c1_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
{
    StringBuilder script = new StringBuilder();
    script.Append("Sys.Application.add_load(function(){");
    script.Append("var combo2 = $find('" + c2.ClientID + "');");
    script.Append("combo2.get_inputDomElement().focus();");
    script.Append("combo2.selectText(0, combo2.get_text().length - 1); });");

    RadScriptManager.RegisterStartupScript(Page, Page.GetType(), "selectText", script.ToString(), true);
}

I hope this helps.


All the best,
