GridLookUpEdit 默认只按displayValue 的值进行自动匹配。
以下通过自定义可以实现多列自动匹配 Code和name 是列名。
void gridLookUpEdit1_Popup
(object sender, EventArgs e)
{
FilterLookup(sender);
}
private void FilterLookup(object sender)
{
Text += " ! ";
GridLookUpEdit edit = sender as GridLookUpEdit;
GridView gridView = edit.Properties.View as GridView;
FieldInfo fi = gridView.GetType().GetField("extraFilter", BindingFlags.NonPublic | BindingFlags.Instance);
Text = edit.AutoSearchText; BinaryOperator op1 = new BinaryOperator("Code", edit.AutoSearchText + "%", BinaryOperatorType.Like);
BinaryOperator op2 = new BinaryOperator("Name", edit.AutoSearchText + "%", BinaryOperatorType.Like);
string filterCondition = new GroupOperator(GroupOperatorType.Or, new CriteriaOperator[] { op1, op2 }).ToString();
fi.SetValue(gridView, filterCondition); MethodInfo mi = gridView.GetType().GetMethod("ApplyColumnsFilterEx", BindingFlags.NonPublic | BindingFlags.Instance);
mi.Invoke(gridView, null);
}
private void gridLookUpEdit1_EditValueChanging(object sender, ChangingEventArgs e)
{
this.BeginInvoke(new System.Windows.Forms.MethodInvoker(delegate{ FilterLookup(sender);
}));
}
