VS 2010 - Remove TreeView ChildNode Image In Designer
Apr 23, 2011
I have a TreeView with several nodes that have child nodes. Whenever I create a child node, it sets the image to a seemingly random icon in my ImageList. There are a couple of properties for the TreeView that have this icon, but nothing happens when I change it to a different one. And besides, it won't let me set those properties to "None."
I tried look at the properties of the child nodes, but everything is set to none and nothing changes. Does anyone have any ideas? In the photo below, you'll see the Internet Explorer node and its child nodes that have the Chrome icon. I need the child nodes to be blank.

I am attempting to update an existing winforms application, that was created with a dataset control on all the winforms pages. I have ported it from VS 2008 to VS 2010 and I need to update the database section and connect it to the SQL backend using traditional code method.In the Solution explorer, when I click on the Dataset files, and click "Exclude From project" I am unable to build the project.Is it advisable to comment out the code lines that refer to the dataset in the .designer.vb files?
my class inherits from TreeView. In it's constructor, it adds nodes. In the Winforms designer, if I put an instance of the Treeview on the Form, the nodes are visible. That's ok.
i am working on a Windows Forms application using VB.net. It basically is an application made in vb 6.0 being upgraded to vb.net. Now i have an idea but i am not sure if it exists.
Say i have a database (My_DB) and it has a table (item_details).
I wish to make dataentry into the elements of item_details table which currently has 6 fields. So i add 6 textboxes and 6 labels and make user enter them, one record at a time.
Say tomorrow i add or remove a field from the table item_details. I want such a mechanism where if the underlying table structure changes, the corresponding number of textboxes and labels must automatically change themselves. i.e. if i remove a column and now i have 5 columns, the form must also have 5 labels and 5 textboxes. Are there any controls to achieve this functionality. Am i talking MVC here?
when I load items in to a treeview, there's several items the same.Say it's like this:[code]How do I delete the duplicate items so it only shows subitem once?
I have a simple Treeview with 1 rootnode and several childs I'm allowing users to add a Group (in the rootnode) in which they can drag and drop other childs. But how can I remove a 'Group' without loosing its childs? If I do a remove it also removes its childs.
I have a listview which I am trying to remove the initial root node's indent. My problem seems to be that I can't even set the indent value of the treeview in it's properties lower than 19, and if I try something like: TreeView2.Indent = 16 16 seems to be the lowest value that makes any visual change. Using visual studio 2008
I am trying to get vb.net to select a single node by id. I then want get all of the childnodes within the id and place them in to textboxes. see code below:
client2 so like this my treeview has be displayed.i can able to display the value in my treeview.my requirement is i need to keep image for the treeview nodes. for example Group1 - sample1.gif server1 -sample2.gif client1 -sample3.gif so i need to keep images to this nodes at run time and i need to chage the image depeds on my need. for example in some situation i will keep sample2
I'm trying to change the treeview image at runtime, i'm trying to apply the above code but nothing is happening. the goal is that i have an image i want to change it to another image at runtime.
I'm a newbie to VB 2008 Express. I have a treeview to which I'm trying to add icons. I've added the icons to the treeview images collection, and I've put an imagelist on the form and added the icons to the listview images collection. I can't seem to work out the syntax required to show the icons.
am trying to display a longer image in the TreeNode Image. I have a 85x12 image that I am trying to display however the image is being cut to 12x12?Does anyone know to display the whole image?
I have a treeview. The root nodes have images set at 30x30 - is there a way to add child nodes with NO image or a smaller image? I can do a blank image, but each child is spaced far apart! I would like the child nodes to be like there is no image... tight and close to each other.
I recently got 102 errors specifically with the designer. I have added the code below:And was surprised to find so many errors.The interesting part was that this problem invoked simplify by adding that line. I did not change any of the elements on the form. And the code above is working with I/O not the design. [code]I also can't view the design of the application itself. I have a backup of the design forms. Should I replace them?
Displaying an image in front of a node's caption of a treeview. i have an imagelist that contains of images and a treeview containing of nodes. I have also assigned the name of the ImageList control to the ImageList property of the TreeView control, as you can see in the following code. here is the structure of my treeview: Code: even i know that by using the image index and the selected index property i can display the images in front of the node caption of a treeview but i cant do it properly and having a few confusions.
I just made a bunch of changes to my program, so I can't just undo what I did. My main form gives me the following error every time I try to load the designer:
Warning1Value cannot be null. Parameter name: objectType
I have rebuild the project with no success. A few other posts have mentioned that there could possibly be a reference to a button or image that no longer exists, but I have no idea which one.
Also, I don't really know what the information below means, but it shows up on the error page under 'call stack', so I figured I would include it
at System.ComponentModel.TypeDescriptor.TypeDescriptionNode.GetRuntimeType(Type objectType) at System.ComponentModel.TypeDescriptionProvider.GetRuntimeType(Type reflectionType)
i have several forms in my solution that have listview controls and each of those listview controls uses the ListViewColumnSorter class that's provided on MSDN. This class requires a few lines of code in the Form_InitializeComponent Method of the Designer.Problem is, each time something on the form is changed, even if it's just a property of one of the controls, the designer deletes the code that I have for the listviews and I have to go back in and add it again.
Just wanted to know if you had some design code which was created, and that is all you have. Can you open this designer code and create the actual working main Form from this? I don't need this designer code for any specific task, just wanted to know if there is a command within VB Studio 2010 that creates the actual Form from the design code. For example; The following piece of designer code is for a simple program that finds the Circumference of a Circle.
