以下是我的要求:
我的问题:
注意:
代码:
protected void addAppButton_Click(object sender, EventArgs e)
{
DropDownList appList = (DropDownList)newEntryFV.FindControl("appList");
TextBox profileTextBox = (TextBox)newEntryFV.FindControl("profileTextBox");
addAppsToTable(appList.SelectedValue.ToString(), profileTextBox.Text.ToString());
}
private void addAppsToTable(string appName, string profileName)
{
Table appsTable = (Table)newEntryFV.FindControl("appTable");
TableRow newRow = new TableRow();
TableCell appNameCell = new TableCell();
TableCell profileCell = new TableCell();
appNameCell.Text = appName;
profileCell.Text = profileName;
newRow.Cells.Add(appNameCell);
newRow.Cells.Add(profileCell);
appsTable.Rows.Add(newRow);
}
解决了我的问题的代码:
[Serializable]
public class securityApps
{
public string secAppID { get; set; }
public string secAppName { get; set; }
public string secProfile { get; set; }
}
protected void Page_Load(object sender, EventArgs e)
{
BindApps();
}
protected void addAppButton_Click(object sender, EventArgs e)
{
DropDownList appList = (DropDownList)newEntryFV.FindControl("appList");
TextBox profileTextBox = (TextBox)newEntryFV.FindControl("profileTextBox");
addAppsToListVS(appList.SelectedValue.ToString(), appList.SelectedItem.Text.ToString(), profileTextBox.Text.ToString());
BindApps();
}
private void addAppsToListVS(string appID, string appName, string profile)
{
securityApps secApp = new securityApps();
secApp.secAppID = appID;
secApp.secAppName = appName;
secApp.secProfile = profile;
((List<securityApps>)ViewState["appsListVS"]).Add(secApp);
}
// Binds apps to Grid View
private void BindApps()
{
GridView appsListGV = (GridView)newEntryFV.FindControl("appsListGV");
if (ViewState["appsListVS"] != null)
{
appsListGV.DataSource = (List<securityApps>)ViewState["appsListVS"];
appsListGV.DataBind();
}
else
{
List<securityApps> appsListVS = new List<securityApps>();
ViewState["appsListVS"] = appsListVS;
}
}

如何在ViewState中存储对象列表(它们甚至可以是简单的键值对)。您可以将该数据用作GridView的DataSource。我认为这是最简单的方法。如果您需要更多详细信息,请与我们联系。
编辑 - 上面的解决方案看起来不错 - 我可以通过为您的ViewState值设置属性来让它更容易一些。
List<securityApps> AppsListVS{
get
{
if(ViewState["AppListVS"] == null
this.AppListVS = new List(securityApps)();
return (List<securityApps>)ViewState["AppListVS"];
}
set
{
ViewState["AppListVS"] = value;
}
}
