Ext.Net 1.x_Ext.Net.GridPanel如何后台遍历GridPanel中的数据?

A:

<Buttons>
<ext:Button runat="server" Text="Submit selection">
<DirectEvents>
<Click OnEvent="SubmitSelection">
<ExtraParams>
<ext:Parameter Name="Values" Value="Ext.encode(#{GridPanel1}.getRowsValues({selectedOnly : true}))" Mode="Raw" />
</ExtraParams>
</Click>
</DirectEvents>
</ext:Button>
</Buttons>

protected void SubmitSelection(object sender, DirectEventArgs e)
{
string json = e.ExtraParams["Values"];

if (string.IsNullOrEmpty(json))
{
return;
}

//XML will be represent as
//<records>
//   <record><Name>Alcoa Inc</Name><Price>29.01</Price><Change>0.42</Change><PctChange>1.47</PctChange></record>
//        ...
//   <record>...</record>
//</records>
XmlNode xml = JSON.DeserializeXmlNode("{records:{record:" + json + "}}");

foreach (XmlNode row in xml.SelectNodes("records/record"))
{
string name = row.SelectSingleNode("Name").InnerXml;
string price = row.SelectSingleNode("Price").InnerXml;
string change = row.SelectSingleNode("Change").InnerXml;
string pctChange = row.SelectSingleNode("PctChange").InnerXml;

//handle values
}

List<Company> companies = JSON.Deserialize<List<Company>>(json);

foreach (Company company in companies)
{
string name = company.Name;
double price = company.Price;
double change = company.Change;
double pctChange = company.PctChange;

//handle values
}

Dictionary<string, string>[] companies1 = JSON.Deserialize<Dictionary<string, string>[]>(json);

foreach (Dictionary<string, string> row in companies1)
{
string name = row["Name"];
string price = row["Price"];
string change = row["Change"];
string pctChange = row["PctChange"];

//handle values
}
this.ResourceManager1.AddScript("Ext.Msg.alert('Submitted', 'Please see source code how to handle submitted data');");

}
