Using this function i can check child node when checking parent.I want to do opposite.Once i uncheck parent child also gets uncheck.It is possible using this same function.?

I have a grid of RadioButtons, and need some help in Check / Uncheck acording to data collected from a .txt file.
The .txt file contains a list like this:
A01,a B01,b C01,c A02,a B02,b C02,c
I have set up in a grid formation RadioButtons, and named them A01,B01,C01,A02,B02,C02. I have loaded the .txt file in an array, and want to use the first 3 letters in the array to point to the RadioButton.
Problem: How do I get the string "A01" from the array to point to the RadioButton control?
I use a SqlDataAdapter to fill a DataTable and then set that DataTable as the DataSource for a DataGridView. All works well. Then I add a column at the beginning of the DataGridView that will allow a user to check/uncheck a row for further processing. All works well. Then I display this to the user. All works well.
Since there are many times when the DataGridView could be displaying hundreds or maybe thousands of records, I have a button that will "Check All" records and another that will "Clear All" records. These work fine, but I've noticed a serious performance lag. Other test code that I've got shows that in an unbound DataGridView, even a large one with 50+ columns and 5000 rows, checking or unchecking all of these fields takes mere fractions of a second. (One test with 50 columns and 50,000 rows still only takes 0.334 seconds to check all of the rows.)
In my testing (with my current code), checking/unchecking 500 rows takes 15 seconds. Is this because the DataGridView is databound? If so, is there a way to UNbind it (making it simply a stand-alone set of data)? I don't need to push updates back to the server, so there's no danger in removing any databinding. I've even toyed around with this (to make the DGV unbound):
I have a checked list box having some items .When I click any item it first select the item and then when I again click it then check box is checked/unchecked How to change this behavior means I want to perform selection and check/uncheck action in a single click.
I have data grid view with checkbox as unbound column and a button at the bottom and when button is clicked i want to check all rows in the datagrid view i.e check the checkbox if it is not checked for all rows in datagridview. If button is clicked again i want to uncheck the checkbox for all rows if the check box is checked.
how to check and uncheck all asp.net checkbox on single checkbox check ?I have 5 asp.net checkbox on webform i want when 1 single checkbox checked then all checkbox will be cchecked and if checkbox is unchecked then all checkb ox will be unchecked ..
I have a requirement for a new application development where I must present some information to the user for selection via drag and drop. VB offers the TreeView control which would work nice, however the user does not like the Treeview control's presentation. The user wants a control that work similar to the Mac's Finder control while in column view.
Apple's Mac Finder Control works similar to window's treeview. Finder has a nifty view capability that my users would like in some new development that is being done. The finder supports a "column" view. Similar to the treeview, it starts out in a root list. The difference being, when a user makes a selection and clicks on a node, the node doesn't expand, the sub nodes appear on the pane to the right of the list. Clicking on a sub node, will cause the pane to split again and the items within that sub node appear to the right again.
This will happen again and again with the left pane getting narrower as the user drives deeper into the sub nodes. That is what I am trying to replicate. Obviously, once the user reaches the base list of items, we have to support drag and drop capability. Does anyone know of a control for VB.NET that work similar to the Mac's Finder control?
Is there a way to tell when clicking on a node in a TreeView whether or not that node already has 1 level down populated within the control? That is, I have code which populates a TreeView 1 level down. I need to put some validation code which checks to see if this level has already been populated before the code that acutally populates it.

To set the checked state of the child node to its parents node i used this code.
mycode vb Private Sub CustomerFields_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles CustomerFields.AfterCheck

I also found the following code on msdn. Whats the difference b/w the two. Both of them works
vb Private Sub CheckAllChildNodes(treeNode As TreeNode, nodeChecked As Boolean) Dim node As TreeNode For Each node In treeNode.Nodes
I have a treeview with nodes being represented as checkbox.
All works fine i.e when a parent nod is checked, its child and sub child should be checked as well but it won't check only the first subchilds and i am not able to find the solution, i have debugged it many time, but still not able to figure the solution.
I tried finding the solution on the web, but didn't got the proper solution. Below is the code which i am using in my form.
Private Sub trvModule_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles trvModule.AfterCheck, trvReports.AfterCheck, trvMasterAccess.AfterCheck
I was wondering how I would go about placing a check in the checkboxes for each child node of a parent node in a TreeView control, if I was to check the parent node.
For example: Parent 1Child 1 Child 2 Child 3
If I was to check "Parent 1" how would I be able to make that event place a checkbox beside all of the child nodes of "Parent 1"? (Child1, 2, and 3.)
I am trying to insert spaces between Images and check boxes on a treeview node, in a windows form app i.e. checkbox (spaces) image (spaces) node text rather than default format checkbox Image node text
I am making a user control named MultiSelect, which consists of a textbox. In this textbox I put substring. I want the user control to show a treeview outside the MultiSelect boundaries where items matching the substring will be shown.
For me its no problem to make a treeview inside the MultiSelect boundaries but I need to save space on the original form where a MultiSelect control will appear, so I need to do it like the treeview will appear and after I choose items, it will disappear
Basically, I have a view (can be converted into a store procedure) with two tables NODE and CONTACT. NODE is the parent table (NodeID) with the foreign key field in CONTACT (NodeID). The query works fine. I would like the treeview to look like this
I have a tier application based on this video url... So far the client application only has a reference to the Business Logic (not Data Access).If i needed to tie a control such as a TreeView to list certain data fields from my table then where and how should i do that? For example i could write a For each statement to iterate through the table which returns the item from a table or i could do it in the WCF service app but how does this tie in with a control such as TreeView especially when there are no references?
Does anyone knows how to achieve UI like the attached image. I need to have a Treeview control which will have nodes & child nodes and each node should have a ComboBox control next to it.
I am using the following code to add all files and sub-directories to a Treeview control. The user can select a directory (using a folder browser dialog) and this code will add that directory, and all it's files and sub-directories, to the Treeview:

I have tried a few ways, mainly 'copying' the code from this recent codebank submission. However, I keep getting the obvious cross-thread call issue that I am adding nodes to the 'node' parameter, which is not allowed.
I am at a loss at how to do this otherwise. How can I update a Treeview like this if I have to recursively add nodes to the 'node' parameter, which is not 'available' in a separate thread?
I've created a treeview that is going to represent a 'table of contents' for a Word template I use frequently and I need to add checkboxes to each node of the tree view.
Here is some of my code so far: tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(2), tvwNext, , "3. Statment of the Issue and Solution" tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(3), tvwChild, , "3.1 Issue Details" tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(4), tvwNext, , "3.2 Solution Details" What to add to these lines to simply display a checkbox next each line?
I have a treeview control with check boxes. when I check the parent node, all the children check too. The problem is, I want the parent check box to automatically uncheck if one of the children is unchecked.
