Populate On Demand A TreeView With Datas In XML?

Feb 25, 2010

I have a large XML file (3000+ nodes) that I want to represent in a TreeView on ASP.NET. I cannot databind it to a XMLDataSource because loading the TreeView will then be way too slow (I never even waited long enough to see it finish...)

So the solution for this would be to use the PopulateOnDemand property of the TreeNodes to load data only when needed. Problem is, I can't think of a way to acheive this...

How can-I, based on the ID of a node, search a XMLDocument to get all the childnodes of the node having this ID?

XML would look like that:

<document ID=1>
<document ID=2>
<document ID=3>
</document>
</document>
<document ID=4>
</document>
</document>

There are nor rules on how much levels it can go down or anything...

I am trying to simulate the file system like explorer using a treeview. I would like to have the application in the server but is the starting root limited to where the application is?

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).

Populate Treeview Based On XML Attribute Ids?

May 25, 2010

I'm currently working on a Web Site application project that requires a treeview to be heirarchically structured based on the attribute ids of each node rather than the format of the XML.

[Code]....

At present the above is lining up all names under each other, I would like the hierarchy to be based on the attribute parentid and Id. For example: Jane Smith should be a child of Joe smith and Bob Turner is a Child of Jane Smith.

Databases :: Populate Treeview Control From MySQL?

Apr 24, 2010

I have searched a while for a good solution for this, but i have only found solutions with XML files and mssql.

I have 2 tables. Table parent holds the parent nodes and table child holds the childnodes related to the parentnodes.

Table parent looks like this: pID as integer (pk), parentName as varchar

Table child looks like this: cID as integer (pk), parentID as integer, childName as varchar

I want to populate the treeview with data from these tables! How can i do that?

Reduce The Time Taken To Populate Tree Node In C# Treeview?

Dec 15, 2010

I am binding the XML Data to treeview using XMLDataSource. Its working fime, but when the Number of nodes and childnodes increases, the treenode expand and to display the content in iframe takes moer time.

<asp:TreeView ID="TreeView1" OnSelectedNodeChanged = "OnClick" runat="server"
ExpandDepth="0" ShowExpandCollapse="true" ForeColor="Red" Font-Underline = "false"
ondatabinding="TreeView1_DataBinding" CollapseImageUrl = "Resources/TocColapse.bmp" ExpandImageUrl = "Resources/TocParent.bmp" Font-Names="Arial" >
<SelectedNodeStyle Font-Underline="false" BackColor="White" ForeColor="#0483e0" />
<NodeStyle Font-Size="11pt" ForeColor="white" HorizontalPadding="5px"
NodeSpacing="0px" VerticalPadding="0px" Font-Underline = "false" />
<ParentNodeStyle ForeColor="#0483e0" Font-Underline = "false" />
<LeafNodeStyle ForeColor="#0483e0" Font-Underline = "false" ImageUrl = "Resources/TocChild.bmp" />
</asp:TreeView>
<asp:XmlDataSource ID="XmlDataSource1" runat="server" XPath="/*/*" EnableCaching = "false" ></asp:XmlDataSource>
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]);
}

Javascript - Executing A Jquery Effect On Demand?

Mar 12, 2011

I was looking the Highlight effect of Jquery's. That effect is really the one i would like to add in my webpage.

By looking at the the source code, i noticed that the effect will be reproduced on user's click of the div.

$("div").click(function () {
$(this).effect("highlight", {}, 3000);
});

In my webpage i have an ImageButton

<asp:ImageButton ID="btnFavorite" runat="server" ImageUrl="~/Images/Favorite.png"/>

I would love to perform the highlight effect to the div, when the user clicks on the image button. Is it possible?

UPDATE: If it is possible, could i use something like "OnClientClick=" of the ImageButton, since the imagebutton controls are added dynamically to the webpage?

Databases :: Way To Access Datas Using SQL?

Jul 12, 2010

I read a lot of tutorials to learn what was the way to manage accessdata on a MySQL database from my ASP.NET, but there still something to whichremains unclear is the formatting of data and the ideal time to do so.For example, if I have a sentence like the following:"Je voudrais t'aider résoudre ton problème"
When I pass the variable that contains this sentence, I wonder who the quotea problem because the SQL query in this setting look like this:"'I want to help you solve your problem'The quote of "t'aider" comes as the end of ther string in the query string. So I have to the format the string to double the quote to be able to pass it in the database..Maybe I missed the good tutorials, so if you have any links
