    send extra parameters on blur event of textfield editor inside gridpanel

    i have a situation where i need to multiply values of two columns in a gridpanel and display the result in a third col.
    i want to send the value just entered into a textfield as an extra parameter to a function i have where the calculation takes place

    how do i send the value of a textfield in a gridpanel as an extra parameter after the blur event??
    do i need to use another event??

    Hi,

    Please investigate the following example.

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            Store store = this.GridPanel1.GetStore();
            store.DataSource = new object[] 
            { 
                new object[] {"1", "2" },
                new object[] {"3", "4" },
                new object[] {"5", "6" }
            };
            store.DataBind();
        }
    }
</script>
