I'm populating a treeview dynamically. On OnTreeNodePopulate I call a sub and populate the Parent nodes. I do not want to populate the child nodes at this time. Upto this point it works fine.
Now I would like the user to click the parent node and then populate the child node. I tried to use TreeNodeExpanded, but that is called for each parent node, so that didn't work.

I have some data that I am putting on a treeview and have a checkbox on the page to decide if the user wants to order the nodes by date or type.
To do this I need to check if the code has already added a child node so when grouping by the type I don't put it in lots of times.
Lets say I have Type 1 and Type 2 and each have 3 items that would fall under these I want to achieve:
Type 1
Item 1
Item 2
Item 3
Type 2
Item 1
Item 2
Item 3
Instead of:
Type 1
Item 1
Type 1
Item 2
etc etc etc

I'm trying to get my treeview control to work where a user clicks on a parent node. The node will expand.Then, the user clicks on another parent node and that node expands while the previous parent node stays expanded. My problem is that when I expand one parent node, another expanded parent node collapses.What am I doing wrong?

In OnDataBinding event of treeview I implemented the following code:
TreeNodeBinding[] TreeNode = new TreeNodeBinding[Count];
for (int i = 0; i < Count; i++)
{
TreeNode[i] = new TreeNodeBinding();
TreeNode[i].DataMember = TableOfContents[i].GetElementName();
TreeNode[i].TextField = TableOfContents[i].GetFirstAttributeName();
TreeNode[i].ValueField = TableOfContents[i].GetSecondAttributeName();
// TreeNode[i].Target = "contentFrame";
TreeView1.DataBindings.Add(TreeNode[i]);

I have an excel sheet which has several parent records/rows and every parent row/record has several child sub-records under it. I have a field called ID which is of the type String as it contains a mixture of characters and numbers and is common for both parent and child records. How do I store the parent and child records in separate database tables, retrieve them and display them in a nested gridview?
View 1 Replies I have nested gridviews, in the outer grid I am displaying the question and in the inner grid 4 options are displayed in radiobuttons. I have kept Lock Answer button inside Item Template in inner gridview , so this button is coming with each and every question and when i click on Lock Answer button in front of any question, its saving the corresponding answer in the database. For ex, if there are 10 questions this button is coming with all the questions, all the questions are on single page and all are multiple choice. Now everything is working mine, my requirement is that I need on 1 common Lock Answer button at the bottom of the page and not with all the questions. And when I click on that common button it should run for all the questions that are displayed on the screen at should fetch and update each unique answer corresponding to that question in the database. Below is my code:
<asp:GridView ID="gvouter" runat="server" GridLines="None" AutoGenerateColumns="False"
AllowPaging="false" OnRowDataBound="gvouter_RowDataBound" Width="100%" OnRowCommand="gvouter_RowCommand"
OnPageIndexChanging="gvouter_PageIndexChanging" >
<PagerSettings Position="Top" />
<Columns>
<asp:TemplateField>
<ItemTemplate>

View 3 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
