[Solved] Have another default telerik filter

[Julien]

Hi

In an asp.net mvc telerik grid, the default filter is "is equal to", is it possible to have instead by default another option? In my case I would like to have by default "contains", because it's the one we use 99% of time, and it's an operation we do often.

Thank you

Hello Julien,

You could easily achieve this with the following function hooked to the OnLoad event of the Grid.

function onGridLoad(){
        $('.t-grid-filter').one('click', function () {
            var container = $(this).data().filter;
            $('.t-filter-operator',container).val('substringof');
        });
}

I hope this helps.

Exactly what I needed, thank you very much

I just remarked a problem with this:

We have a non-ajax binding. 

So if we do the following:
1. Open the filter by clicking on the filter icon
2. Change the selected filter type to another one
3. Type a value for the filter
4. Apply
5. -- The page reload --, the filter is correctly made
6. Click again on the filter icon
7. It's not the current filter type which is displayed, but the default one we set with the JS code

Any idea about how to make a workaround for this?

It makes one month that we didn't get any answers, can you please respond?

same problem for me

Hello,

The shared work-around is applicable only for Ajax bound Grid. When using server binding the whole page is reloaded and the selected filter will be changed by the code  I shared. I am sorry but there is no simple work-around  for the server binding scenario.

This code works for me:

function onGridLoad() {
    $('.t-grid-filter').one('click', function () {
        var container = $(this).data().filter;
        $('.t-filter-operator', container).each(function () {
            var value = $(this).next().val();
            if (value === "") {
                $(this).val('substringof');
            }
        });
    });
}

Its sort of a hack but it does the job :)
