Hello all,
In the GridPanel with Remote Filtering example (https://examples2.ext.net/#/GridPane...ilters_Remote/), I noticed that the string filter is applied as soon as there is a change in the text field. I would like to filter only after entering the complete string, e.g. by activating the checkbox next to "Filters" after completing the filter string.
Is that possible?
You may consider a StringFilter override like in the code sample below:
Code:<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<%@ Import Namespace="System.Data" %>
<script runat="server">
private DataTable TestData
{
get
{
var updated = new DateTime(2013, 01, 20);
var addDays = 1;
var dataTable = new DataTable();
dataTable.Columns.AddRange(new DataColumn[] {
new DataColumn { ColumnName = "company", DataType = typeof(System.String) },
new DataColumn { ColumnName = "industry", DataType = typeof(System.String) },
new DataColumn { ColumnName = "price", DataType = typeof(System.Double) },
new DataColumn { ColumnName = "change", DataType = typeof(System.Double) },
new DataColumn { ColumnName = "pctChange", DataType = typeof(System.Double) },
new DataColumn { ColumnName = "lastChange", DataType = typeof(System.DateTime) },
new DataColumn { ColumnName = "visible", DataType = typeof(System.Boolean) },
});

Hi Vadym,
thank you very much. Your solutions works great.
I am sure this will also help others.
Thanks again,
Manni
You're very welcome Manni :)
