Hi,
Is it possible to get teh value of filtered column on button click. generally when we input some text and select a filter option then itemcommand is triggered an dwe can get the value from gridcommandeventargs. But, is it possible to get the value of that filtered column on click of a seperate button above the grid?

OR is it possible to have filter options(liek what we have for a grid-basic filtering options) and a custom text filter using filtertemplate inside a gridboundcoulmn

TIA

Hi Guys, I have been playing with this and can't figure it out.

The setup.  I have two comboboxes.  The first is a list of countries.  The second is a cascading box and displays States, dependent on the country selected in the first combo box.  Here is how I want it to work. 

1. When the page loads, the Countries Combobox (RadCombobox1) is visible and lists the countries.  The States Combobox (RadCombobox2) is not visible.

2. After the user selects a country, it fires the OnClientSelectedIndexChanged="fired" javascript function which in turn fires the RadComboBox2 requestItems event passing the countryID value.

3.  The RadComboBox2 requestItems event then populates the state list for Australia (Country ID 1), Canada (Country ID 7) or the USA (Country ID 45), or nothing if it is any other country.  Then I want the RadComboBox2 to be visible and dropped down if the country is Australia, Canada, or the USA, and if it is not then I want it to be visible but looking like a text box (RadComboBox2.ShowToggleImage = False

,RadComboBox2.ShowDropDownOnTextboxClick = False) so that they can type in their state.

 4.  All seems to work ok, except that the RadComboBox2.ShowToggleImage = False and RadComboBox2.ShowDropDownOnTextboxClick = False does not work unless there is a postback (such as clicking the button).

5.If I use RadAjaxManager (on RadCombobox1 to update RadCombobox2) then it doesn't work because the requiredfieldvalidator on name won't allow the postback unless a the name field is filled out.  This is a striped down version, in real life there will be many textbox inputs above and below the country and state comboboxes, and they will have requiredfieldvalidators.  Is there a way of turning these validators off for the RadAjaxManager postback?

 6. On another note, was there a simpler way of hiding RadComboBox2 when the page was first loaded instead of using a literal to insert javascript.  HideCombo does not work. If I change the visibility then it does not render, so that doesn't work.  If I use set_visibile(false) in the pageload()then it disappears on postback.

Many thanks in advance.
