I have treeview with checkboxes.
[Code]....
when i check Treenode with Text='Velocity', all the three child nodes will get checked. I want only the count of child checked nodes. How can be it done.
I have a treeview in my .aspx: <asp:TreeView ID="tvDocCatAndType" runat="server" /> Not much else going on in the page -- two <asp:LinkButtons> and one <asp:Label>; the page is a child of a master page, so these controls are within a <asp:Content> control. I populate the treeview in code -- just 3 node levels, including the root node. All nodes have checkboxes, and I initialize all node.Checked to true. I have some Javascript to do the usual check/uncheck up and down the tree as parent and child node checkboxes are toggled.
No matter how many checkboxes I clear in the UI, on postback every single node has node.Checked = true regardless of the state of the checkbox in the UI. This is not the first time I've used a treeview, but I've never had this problem before. I created this page by light adaptation of an earlier project that works fine.
In my Treeview i have for all nodes checkboxes.
parent
child
leaf
leaf
leaf
parent
child
leaf
child
leaf
1. when i check leaf - i want to have checked child and parent too
2. when i check parent - i want to have checked child and leaf
---
3. on a save button i only want to save checked leaf to DB - if they are not checked delete from DB
i added one treeview control in aspx page .All parent and child nodes are working perfect in this aspx page.
Now this same code i pasted in an ascx page and that ascx page i called through DNN website.That time parent node display is coming properly,but when i click on the parent node child nodes are not showing up?
How can I add a Treeview to the DropDownList for show child and parent record..
View 1 RepliesI have a treeview and all nodes are check box, when user clicks on a button, how can I get all the checked child nodes belongs to specific parent? I wanna something better...
private TreeNodeCollection GetCheckedNodeForParent (string parentNode)
{
TreeNodeCollection treeNodeCollection=new TreeNodeCollection();
foreach (TreeNode node in tvBaseline.FindNode(parentNode).ChildNodes)
{
if (node.Checked)
treeNodeCollection.Add(node);
}
return treeNodeCollection;
}
I using TreeView with ShowCheckBoxes="All" in an ASP.NET 3.5 web application and for some reason the checked nodes are not returned in order. Lets say I have nodes A,B,C and I select B and C and hit the save button and when I check the CheckedNodes property of the Treeview the checked nodes are in order (B,C). But the next time when I go back to the page and select the node A the order is being returned B,C,A. What could be the reason for this behavior?
View 1 RepliesC#- bind treeview runtime using dataset and data table
simple example
the problem is actually in the subject. I have custom control that uses treeview. The control is added dynamically. Nodes for this treeview are populated on demand. Treeview nodes can be checked. I recreate this control on page load event, but still CheckedNodes is empty if checked nodes were added dynamically (added on demand).
View 2 RepliesI'm very new to xml so I hope I'm not asking any silly question here. I'm currently working on populating a treeview from an XML file that is not hierarchically structured. In the xml file that I was given the child and parent nodes are defined within the attributes of the item element. How would I be able to utilize the attributes in order for the treeview to populate in the right hierarchical order. (Example Mary Jane should be a child node of Peter Smith). At present all names are under one another.root
<item parent_id="0" id="1"><content><name>Peter Smith</name></content></item>
<item parent_id="1" id="2"><content><name>Mary Jane</name></content></item>
<item parent_id="1" id="7"><content><name>Lucy Lu</name></content></item>
<item parent_id="2" id="3"><content><name>Informatics Team</name></content></item>
<item parent_id="3" id="4"><content><name>Sandy Chu</name></content></item>
<item parent_id="4" id="5"><content><name>John Smith</name></content></item>
<item parent_id="5" id="6"><content><name>Jane Smith</name></content></item>

i'm new one to Asp.net (3.5).. plz tel me how to calculate the node, childnode, sub childnode and so on.. and tel me how to retrive value of all...
Using Recurisive i can do this but i don't how to do..
I have a code that load hierarchy( nodes) into trew view.. by selecting different date, the hierarchy result from SP will show in the treeview..
the problem is even though I select a different date.. the result( node) of previous date is still showing in addition to the new hierarchy result...
it;s like the new result node is appended to existing node.. instead of refreshing the node and showing only the new result. How can I clear out the treeview nodes before adding new nodes from different date?
how can add , edit, delete nodes and sub nodes in treeview in vb.net 2005 and sql server2005

View 1 RepliesShould be easy but I cannot find a property which allows me to right align the nodes in a treeview.
I've tried adding text-align: right in a CSS declaration linked from NodeStyle > CssClass. Nothing.
Second: Is there a way to select more than one node in tree view (like we do in Windows Explorer, by pressing SHIFT or CTRL) ?
View 2 RepliesIn my asp.net application I'm using TreeView control, and at some point I noticed that TreeView.Nodes property doesn't return all the nodes, so I'm curious how can I get ALL Nodes of TreeView control to iterate through them in foreach loop, any tricks, or I miss something?

View 1 RepliesI'm coding an Webpage in VS.NET 2010[C#] that scans the Serial Number of Product into a Treeview in a Work Order > Box > Product hierarchy.
What I wanted to do was to use the following to Remove the ChildNodes:
//Use the GetEnumerator method to create an enumerator that contains the root node data.
IEnumerator nodeEnumerator = myTreeView.CheckedNodes.GetEnumerator();
// Iterate through the enumerator to display the root nodes.
while (nodeEnumerator.MoveNext())
{
/In here I would like to Remove the TreeNode
//MessageBox(((TreeNode)(nodeEnumerator.Current)).Text);
}
}
else
{
MessageBox("The TreeView control does not have any nodes.");
}
See this XML:

I want to get the total count of nodes from this xml dynamically (C#).
How can I do it? Any sample code?
