Arcgis server for net hides and controls the bound toc

Hello everyone, I have been updated for a long time. Recently, my project is busy. I am working on MAP CACHE. Tens of GB of data has produced millions of files. The system is suffering, I have the opportunity to write some ideas and share them with you. The following is the code in Layer Control!

 

Reference Column

HideLayer (Map1, "kuwait ");

Private void HideLayer (ESRI. ArcGIS. ADF. Web. UI. WebControls. Map map, string layerName)
{
// Loop through all map services in the Map/MapResourceManager
Foreach (IMapFunctionality mapFunct in map. GetFunctionalities ())
{
String layerId = GetLayerId (layerName, mapFunct );
// Turn layer off if found
If (! String. IsNullOrEmpty (layerId ))
MapFunct. SetLayerVisibility (layerId, false );
}

// Find Toc buddied to the Map, if any
Toc tocCtrl = FindControlOfType (typeof (Toc), Page. Controls) as Toc;
If (tocCtrl! = Null & tocCtrl. BuddyControl = map. ID)
{
// Remove Toc nodes for layer in each resource, if found
Foreach (TreeViewPlusNode resource in tocCtrl. Nodes)
{
TreeViewPlusNode nodeToRemove = null;

Foreach (TreeViewPlusNode layerNode in resource. Nodes)
{
TreeViewPlusNode matchNode = FindNodeRecursive (layerNode, layerName );
If (matchNode! = Null)
{
NodeToRemove = matchNode;
Break;
}
}
If (nodeToRemove! = Null)
NodeToRemove. Remove ();
}
}
}
Private string GetLayerId (string layerName, IMapFunctionality mapFunctionality)
{
String layerId = String. Empty;

// Get layerIDs/names for the service
String [] layerIDs, layerNames;
MapFunctionality. GetLayers (out layerIDs, out layerNames );

// Loop through names, find matching ID
For (int I = 0; I <layerIDs. Length; I ++)
{
If (layerNames [I] = layerName)
{
LayerId = layerIDs [I];
Break;
}
}
Return layerId;
}

Public static System. Web. UI. Control FindControlOfType (Type type, ControlCollection controls)
{
// Finds the first control matching the Type in the control collection
Foreach (System. Web. UI. Control ctl in controls)
{
If (type. IsInstanceOfType (ctl ))
Return ctl;
Else if (ctl. HasControls ())
{
System. Web. UI. Control childCtl = FindControlOfType (type, ctl. Controls );
If (childCtl! = Null)
Return childCtl;
}
}
Return null;
}

Private TreeViewPlusNode FindNodeRecursive (TreeViewPlusNode node, string nodeName)
{
If (node. Text = nodeName)
Return node;

Foreach (TreeViewPlusNode node2 in node. Nodes)
{
TreeViewPlusNode childNode = FindNodeRecursive (node2, nodeName );
If (childNode! = Null)
Return childNode;
}
Return null;
}

 

I only want to delete all the layers in a service by myself. For example, there are too many small slices in the remote sensing image, so users are not allowed to click here :-)

 

Protected void Page_PreRenderComplete (object sender, EventArgs e)
{
// If no tasks have been defined, hide the tasks panel
// If (TaskMenu. Items. Count = 0) Tasks_Menu_Panel.Visible = false;
// Check to see if any of the resource items are non-pooled
If (! Page. IsCallback |! Page. IsPostBack)
{
// CloseHyperLink. Visible = HasNonPooledResources ();
OverviewMap ov = Page. FindControl ("OverviewMap1") as OverviewMap;
If (ov! = Null &&! OverviewMapResourceIsValid (ov ))
Ov. OverviewMapResource = Map1.PrimaryMapResource;

Int tocnum = Toc1.Nodes [1]. Nodes. Count;
If (tocnum> 0 ){
For (int I = tocnum-1; I>-1; I --)
{

Toc1.Nodes [1]. Nodes [I]. Remove ();
}

// The above code should be put in this method. If it is put in another cycle, the data in toc has not been loaded yet ..
}

}
CopyrightTextHolder. Visible = HasCopyrightText ();
