Please try to modify the array of FilterType property into the following.

function ChangeFilter() {
    wg_Global.FilterType = new Array(["NotSet", 0], ["GTET", 1], ["GT", 2], ["ET", 3], ["NET", 9], ["LTET", 4], ["LT", 5], ["Like", 6], ["NotLike", 11], ["NotContain", 17], ["NotBetween", 10], ["IsNull", 12], ["NotIsNull", 13], ["IsEmpty", 14], ["NotIsEmpty", 15]);
}

The script will remove the “IsBetween” and not add the “Contains” from WebGrid filter list. Should you need to remove the “Not Between” and “Not Contain” from the filter list as well, the following script will suit your need.

function ChangeFilter() {
    wg_Global.FilterType = new Array(["NotSet", 0], ["GTET", 1], ["GT", 2], ["ET", 3], ["NET", 9], ["LTET", 4], ["LT", 5], ["Like", 6], ["NotLike", 11], ["IsNull", 12], ["NotIsNull", 13], ["IsEmpty", 14], ["NotIsEmpty", 15]);
}

Please let us know whether this helps or not.

Thanks Yudi,

Yes, I need to remove "Is Between" and "NotBetween" filter from Date column only. As per your suggestion, If I use your given filter array, It will remove contains from Date column and other string column also.

  wg_Global.FilterType = new Array(["NotSet", 0], ["GTET", 1], ["GT", 2], ["ET", 3], ["NET", 9], ["LTET", 4], ["LT", 5], ["Like", 6], ["NotLike", 11], ["IsNull", 12], ["NotIsNull", 13], ["IsEmpty", 14], ["NotIsEmpty", 15]);

My requirement is that Contains filter should be added on other column except Date type so this array will not work.

Please give me another solution.

Thanks

Sachin

Unfortunately, it is not possible to customize the filter type option per column. The filter type customization will be applied globally, means all columns will have the same filter type.

Should you need to implement this feature, you can submit this as feature request to the WebGrid development team.

Hope this helps.
