Validating filter criteria before custom filter

I’d like to suggest you to utilize the “OnBeforeRequest” client side event. OnBeforeRequest client side event specifies the client side (Javascript) function that will be invoked when request action to server is about to be made.

Below is the snippet code that shows a simple sample of script that iterates through all the cells of WebGrid filter row and obtain its inner text.

<script language="javascript" type="text/javascript">
    <!--
    function WebGrid1_OnBeforeRequest(controlId, action) {
        var WebGrid1 = ISGetObject(controlId);
        var rootTable = WebGrid1.RootTable;
        var filterRowEl = rootTable.GetFilterRow();
        var filterRowLength = filterRowEl.cells.length;
        var i = 0;

        for (i; i < filterRowLength; i++) {
            var filterText = filterRowEl.cells[i].innerText;

            //your validation code in here
        }

        return true;
    }
    -->
</script>

Hope this helps.

Validating filter criteria before custom filter

Hi,

Im setting up a custom filter on the grid, using the "OnCustomFilter" event, and wondered if there is an easy way to perform some client side validation on the value(s) the user enters in the filter inputs on the grid?

thanks
