Session State in Asp.Net

Session State

Sometimes you want your web page to 'stay alive'. That is, if a user is filling out a complicated form, you do not want the session to time out before they are finished. The user could get very angry and rightfully so: You might even get yelled at!

A MulticastDelegate has a linked list of delegates, called an invocation list, consisting of one or more elements.

The ASP.NET Framework includes two controls you can use to display text in a page: the Label control and the Literal control. Whereas the Literal control simply displays text, the Label control supports several additional formatting properties.

Create an override for a datagrid within a user control(WPF)

The XAML

<UserControl>
 <Grid>
        <toolkit:DataGrid  ItemsSource="{Binding Source={StaticResource DocumentsVS}}" AutoGenerateColumns="False" CanUserAddRows="False" CanUserDeleteRows="False"
                FontSize="16" Name="_dgDocuments" Style="{StaticResource EklektosDataGridStyle}" . . . >
</UserControl>

OR

<local:MyDataGrid x:Name="dataGrid"/>

In case you want to override the OnCreateAutomationPeer of your dataGrid, you have to subclass the dataGrid -

public class MyDataGrid : DataGrid

{

    protected override AutomationPeer OnCreateAutomationPeer()

    {

        return null;

    }

}

And in constructor of your UserControl -

public CDocumentChecklistView()

{

    InitializeComponent();

    AutomationPeer a = UIElementAutomationPeer.CreatePeerForElement(dataGrid);

}
