Hi jmcantrell,
Please use the SetHidden property of ColumnModel.
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.Store.Primary;
store.DataSource = new object[] {
new object[] {"test11", "test12", "test13"},
new object[] {"test21", "test22", "test23"},
new object[] {"test31", "test32", "test33"}
};
store.DataBind();
}
}
protected void Hide(object sender, DirectEventArgs e)
{
this.GridPanel1.ColumnModel.SetHidden(1, true);
}
protected void Show(object sender, DirectEventArgs e)
{
this.GridPanel1.ColumnModel.SetHidden(1, false);
}
</script>
