ComboBox update another ComboBox

[tim]

hi

I've run into another wee issue, I have a text box (bog standard one) that when I type in part or all of a company name populates a dropdown commbobox (with checkboxes), that all works fine what  need to do is when they select a company from the new list I want it to update another list, but I dont seem to have anyway of capturing the fact that the text has changed in the combobox. I've tried all manner of ways, behind and in the page but I cant get the  OnTextChanged="CaseType_TextChanged" in the same way it works for the text box. Ive tried  ddlCaseList.TextChanged +=new EventHandler(ddlCaseList_TextChanged); but to no avail. I just need to know where to put the the call which captures the event that will fire the event handler!


any thoughts ?

thanks

Hi Tim,

Please refer to the Related ComboBoxes online example which shows how the comboboxes can interact with each other using client-side methods and requesting the items on demand.

hi

I had seen that but couldn't work it out with the checkboxes as well, anyway I have it working now so thank you for that, but..... if I select multiple checkboxes it falls over (no error) just doesnt fire the LoadCases(combo, eventArqs) function at all (its the LoadCities function in the example).

any ideas ?

thanks

sorted, changed the LoadCases function to

function LoadCases(caseList)
{
    casesCombo.set_text("Loading...");
    casesCombo.requestItems(caseList, false);
}

and then call LoadCases(text); from within the onCheckBoxClick(chk) function and this passes it across, loads the item numbers and opens the dropdown for me.
