The following code example demonstrates the use of the CloseVerb property on a WebPartZone control. For the code example to work, you need all the code from the Example section of the HelpVerb property.
The following part of the code example is from the partial class, and contains the code that toggles whether the help verb is enabled or disabled.
Protected Sub CheckBoxList1_SelectedItemIndexChanged(ByVal sender As [Object], ByVal e As EventArgs)
Dim item As ListItem
For Each item In CheckBoxList1.Items
Dim theVerb As WebPartVerb
Select Case item.Value
Case "close"
theVerb = WebPartZone1.CloseVerb
Case "export"
theVerb = WebPartZone1.ExportVerb
Case "delete"
theVerb = WebPartZone1.DeleteVerb
Case "minimize"
theVerb = WebPartZone1.MinimizeVerb
Case "restore"
theVerb = WebPartZone1.RestoreVerb
Case Else
theVerb = Nothing
End Select
If item.Selected Then
theVerb.Enabled = True
Else
theVerb.Enabled = False
End If
Next item
End Sub
protected void CheckBoxList1_SelectedItemIndexChanged(Object sender, EventArgs e)
{
foreach (ListItem item in CheckBoxList1.Items)
{
WebPartVerb theVerb;
switch (item.Value)
{
case "close":
theVerb = WebPartZone1.CloseVerb;
break;
case "export":
theVerb = WebPartZone1.ExportVerb;
break;
case "delete":
theVerb = WebPartZone1.DeleteVerb;
break;
case "minimize":
theVerb = WebPartZone1.MinimizeVerb;
break;
case "restore":
theVerb = WebPartZone1.RestoreVerb;
break;
default:
theVerb = null;
break;
}
if (item.Selected)
theVerb.Enabled = true;
else
theVerb.Enabled = false;
}
}
The other part of the code example is the Web page that hosts the custom control and contains the UI. Notice that the declarative <CloseVerb> element in the zone sets the specific text that represents the close verb in the verbs menu for the WebPart control.
<asp:WebPartZone ID="WebPartZone1" Runat="server">
<CloseVerb Text="Close WebPart" />
<HelpVerb Text="View Help" />
<ExportVerb Text="Export WebPart Definition" />
<DeleteVerb Text ="Delete WebPart" />
<MinimizeVerb Description="Minimize the control" />
<RestoreVerb Description="Restore the control" />
<ZoneTemplate>
</ZoneTemplate>
</asp:WebPartZone>
<asp:WebPartZone ID="WebPartZone1" Runat="server">
<CloseVerb Text="Close WebPart" />
<HelpVerb Text="View Help" />
<ExportVerb Text="Export WebPart Definition" />
<DeleteVerb Text ="Delete WebPart" />
<MinimizeVerb Description="Minimize the control" />
<RestoreVerb Description="Restore the control" />
<ZoneTemplate>
</ZoneTemplate>
</asp:WebPartZone>
Notice also that, because the underlying custom WebPart control--named TextDisplayWebPart-- used in the code example sets the AllowClose property to false in its constructor, the <aspSample:TextDisplayPart> element in the catalog must set the AllowClose property to true, so that the control can be closed in the following code example.
<asp:CatalogZone ID="CatalogZone1" Runat="server">
<ZoneTemplate>
<asp:DeclarativeCatalogPart ID="DeclarativeCatalogPart1"
Runat="server">
<WebPartsTemplate>
<aspSample:TextDisplayWebPart
runat="server"
id="textwebpart"
title = "Text Content WebPart"
width="350px"
AllowClose="true"
ExportMode="All"
HelpMode="Modal"
HelpUrl="TextWebPartHelp.htm" />
</WebPartsTemplate>
</asp:DeclarativeCatalogPart>
<asp:PageCatalogPart ID="PageCatalogPart1" Runat="server" />
</ZoneTemplate>
</asp:CatalogZone>
<asp:CatalogZone ID="CatalogZone1" Runat="server">
<ZoneTemplate>
<asp:DeclarativeCatalogPart ID="DeclarativeCatalogPart1"
Runat="server">
<WebPartsTemplate>
<aspSample:TextDisplayWebPart
runat="server"
id="textwebpart"
title = "Text Content WebPart"
width="350px"
AllowClose="true"
ExportMode="All"
HelpMode="Modal"
HelpUrl="TextWebPartHelp.htm" />
</WebPartsTemplate>
</asp:DeclarativeCatalogPart>
<asp:PageCatalogPart ID="PageCatalogPart1" Runat="server" />
</ZoneTemplate>
</asp:CatalogZone>
After you load the page in a browser, switch the page into catalog display mode, and add the TextDisplayWebPart control to the page. You can use the check boxes to enable and disable the close verb, and you can click the Close WebPart verb in the verbs menu to close the control. After you close the control, if you return the page to catalog display mode, you can click the Page Catalog, select the original instance of the TextDisplayWebPart control that you closed, and reopen it on the page.
