Selecting a Graphic Element on button click using IGraphicContainerSelect - c#

I am having trouble type casting and using the right interfaces. I have a function that loops through all text elements with a specific property set. Once a match is found, I want to be able to select this text element or make it active or highlighted or whatever on the map. Code below.
protected override void OnClick(Item item)
{
IMxDocument pDoc = ValidateInterface.GetMxDocument();
IActiveView pLayout = (IActiveView)pDoc.PageLayout;
IGraphicsContainer pGraphicsCont = (IGraphicsContainer)pDoc.PageLayout;
pGraphicsCont.Reset();
IElementProperties _ElemProps = null;
while ((_ElemProps = (IElementProperties)pGraphicsCont.Next()) != null)
{
if (_ElemProps.CustomProperty is IPropertySet2)
{
ITextElement _textElement = (ITextElement)_ElemProps;
IPropertySet2 _propertySet = (IPropertySet2)_ElemProps.CustomProperty;
MessageBox.Show("Before I compare item to string");
if (item.Caption == Convert.ToString(_propertySet.GetProperty(NAME_STRING)))
{
//Problems start here
MessageBox.Show("Inside the IF statement");
IGraphicsContainerSelect _SelectMyElement = null; // = (IGraphicsContainerSelect)pGraphicsCont;
ITextElement _newTextElement = (ITextElement)pGraphicsCont;
IElement TestElement = _newTextElement as IElement;
_SelectMyElement.SelectElement(TestElement);
}
}
}
}
Nothing is being selected though on my map. I'm looping through each graphic element (IGraphicContainer) on the map. Once I find a match, I want to select that Graphic Element. I am trying to utilize IGraphicContainerSelect to do this. It takes an IElement variable type as a parameter, thus why I'm trying to cast it. But again, noting is being selected. This all happens when I click a button.
Any help on this would be greatly appreciated. Thanks in advance.

Try to refresh your map.
I think the better way using pLayout.PartialRefresh or pScreenDisplay.Invalidate methods.
pLayout.PartialRefresh(esriViewDrawPhase.esriViewGraphicSelection,null,pLayout.Extent)
OR
IScreenDisplay pScreenDisplay = pLayout.ScreenDisplay;
pScreenDisplay.Invalidate(null,false,esriViewGraphicSelection);
pScreenDisplay.UpdateWindow();

Clicking on List Item on Dropdown

I'm having a problem in interacting with a custom dropdown control. It works fine the 1st 6 times, but after that, since the screen is resized, it could no longer locate and click the option in the dropdown control, returning an exception - can't click on hidden control. I tried putting in a itemField.DrawHighlight(); on the control I'm looking for, and it finds it, however it can't click on it. I also tried a to scroll down, but it seems to be not working.
bool addItemCheck = false;
int scrollCheck = 0;
while (Check == false)
{
var addItem= new HtmlButton(window);
addItem.SearchProperties.Add(HtmlButton.PropertyNames.Id, "add-new-item");
Mouse.Click(addItem);
scrollCheck = scrollCheck + 1;
if (scrollCheck > 6)
{
Mouse.MoveScrollWheel(window, -100);
}
var itemDropDown = new HtmlSpan(window);
itemDropDown .SearchProperties.Add(HtmlSpan.PropertyNames.Class, "item-dropdown");
itemDropDown .SearchProperties.Add(HtmlSpan.PropertyNames.InnerText, "Select an Item");
Mouse.Click(itemDropDown );
addItemCheck = itemDropDown.Exists;
}
bool itemBoxCheck = false;
HtmlCustom itemBox = null;
while (itemBoxCheck == false)
{
itemBox = new HtmlCustom(window);
itemBox.SearchProperties.Add(HtmlCustom.PropertyNames.Id, "item-listbox");
var itemField = new HtmlCustom(itemBox);
itemField .SearchProperties.Add(HtmlCustom.PropertyNames.InnerText, item);
Mouse.Click(itemField);
itemBoxCheck = itemBox.Exists;
}
I would really appreciate any help. Thank you.
Try calling the method InsureClickable() on the control before attempting to click on it.
for example:
itemDropDown.EnsureClickable();
Mouse.Click(itemDropDown);
Edit:
if this doesn't work you'll have to scroll down to the item.
try using:
Mouse.MoveScrollWheel()
if that doesn't work also you'll have to map the scroll control and click on it.

C# ListView from Another Function

Please forgive me for such a stupid question. I am sure many of you will find this easy, where I have sent almost half the day reading trying to figure this out.
Here is the problem:
I have a FORM (Form1.cs) made. In that form I created a listview, and named it "ListView1".
Within the Form1.cs, I call a function called FileManager(this), where I pass in the THIS object.
In FileManager.cs I was able to listviewArray= originalForm.Controls.Find("listView1", true) and find that 'listview'.
When I do a listviewArray[0]<-- I can't seem to add a list to it.
FileManager.cs
FileManager(object sender)
{
if (sender != null)
{
originalForm = (Form)sender;
}
}
public void getFiles()
{
filePaths = Directory.GetFiles(hsocDir);
if(filePaths != null)
{
listviewArray= originalForm.Controls.Find("listView1", true);
if(listviewArray != null)
{
ListViewItem lvi = new ListViewItem("text");
// My Array is listViewArray
// How to add things to Lvi to it.
}
}
== Form1.cs
public Form1()
{
InitializeComponent(`enter code here`);
mysql = new MySQLCheck(this);
fileManager = new FileManager(this);
fileManager.getFiles();
}
You can't access element 0 of the collection because the collection is empty. To add an item, use:
listViewArray.Items.Add(lvi);
You need to modify the Items collection instead of the ListView itself for this to work, as ListView is not a collection (its a control).
listViewArray.Items.Add(lvi);
Also in your listview,setting this properties will help :
// Set the view to show details.
listViewArray.View = View.Details;
// Select the item and subitems when selection is made.
listViewArray.FullRowSelect = true;
// Display grid lines.
listViewArray.GridLines = true;

select items from listview

What i'm trying to do is select an item in my listview, and it works! That is it works once, the first time a select an item it go's well, the second time a get an argument out of range exception on features[0].SubItems[1].Text; on the zero.
this is what i have:
private void listViewFeatures_SelectedIndexChanged(object sender, EventArgs e)
{
ListView.SelectedListViewItemCollection features = listViewFeatures.SelectedItems;
string feature = features[0].SubItems[1].Text;
BL_AddReport addReport = new BL_AddReport(this.databaseConnectionString);
Dictionary<string, bool> pictures = addReport.GetpicturesFromFeature(feature);
foreach (KeyValuePair<string, bool> pic in pictures)
{
if (pic.Value) {
pictureBoxCar.Image = Image.FromFile(pic.Key);
}
else
{
pictureBoxEquip.Image = Image.FromFile(pic.Key);
}
}
}
Does anyone know what the problem is?
I'm betting you'd get this exception if you clicked off of the listview as well.
Remember that this event is for selection changes.. which may mean that something was selected and now nothing is. In fact, according to this an event is fired once for every thing that is selected. Take a look at that link for more information and designs around this problem if that is the case for you.
Otherwise just check to make sure that your "features" variable has anything inside of it before indexing into it

Can someone tell me what's wrong with this code?

I'm trying to implement a search as you type (like in iTunes). I am using an ObjectListView. Further, I have a textbox that is used to do the search as shown below:
private void textBoxSearch_TextChanged(object sender, EventArgs e)
{
string txt = textBoxSearch.Text;
TextMatchFilter filter = null;
if (!String.IsNullOrEmpty(txt))
{
filter = TextMatchFilter.Contains(myObjectListView, txt);
}
// Setup a default renderer to draw the filter matches
if (filter == null)
myObjectListView.DefaultRenderer = null;
else
{
myObjectListView.DefaultRenderer = new HighlightTextRenderer(filter);
// Uncomment this line to see how the GDI+ rendering looks
myObjectListView.DefaultRenderer = new HighlightTextRenderer { Filter = filter, UseGdiTextRendering = false };
}
// Some lists have renderers already installed
HighlightTextRenderer highlightingRenderer = myObjectListView.GetColumn(0).Renderer as HighlightTextRenderer;
if (highlightingRenderer != null)
highlightingRenderer.Filter = filter;
myObjectListView.ModelFilter = filter;
}
Can someone figure out why this doesn't work?
The above code is meant to filter search results as the user types in the textbox (Like iTunes does, if you have ever used itunes). Apparently, up to this point, nothing happens. It seems like this code does not even execute.
Per this, the ObjectListView has a property named UseFiltering that is false by default and must be set to true to enable filtering.

Create a VS2010 Addin to collapse every methods of my active document

I'm looking for the source code to collapse every methods of my active document using the VS2010 Addin.
For the moment I parse the text content of the document trying to match if the line is a method signature. If it is the case, I collapse the method.
TextSelection selection = (TextSelection)_applicationObject.ActiveDocument.Selection;
var editPoint = selection.ActivePoint.CreateEditPoint();
editPoint.MoveToLineAndOffset(1, 1);
while (!editPoint.AtEndOfDocument)
{
editPoint.StartOfLine();
var line = editPoint.GetText(editPoint.LineLength).TrimStart();
if (line.StartsWith("public"))
{
selection.MoveToLineAndOffset(editPoint.Line, 1);
_applicationObject.ExecuteCommand("Edit.ToggleOutliningExpansion");
}
// go to the next line
}
Does anyone could tell me if I'm on the good way or if there is an easiest way ?
Maybe I asked not so well my question. My real goal was to collapse all the code : properties, methods, comments with ///, using; but not the regions.
Here is one solution :
// reduce everything like Ctrl+M+O
_applicationObject.ExecuteCommand("Edit.CollapsetoDefinitions");
// save the cursor position
TextSelection selection = (TextSelection)_applicationObject.ActiveDocument.Selection;
var selectedLine = selection.ActivePoint.Line;
var selectedColumn = selection.ActivePoint.DisplayColumn;
// open the regions
selection.StartOfDocument();
while (selection.FindText("#region", (int)vsFindOptions.vsFindOptionsMatchInHiddenText))
{
// do nothing since FindText automatically expands any found #region
}
// put back the cursor at its original position
selection.MoveToDisplayColumn(selectedLine, selectedColumn);
I hope this could help
