The first column displays names from a xml file and the button column just hold delete buttons so i can delete the corresponding item to the left of it (1st column).
How exactly can i retrieve/pass this selected value to a function? In other words when i press the button to the right of the name, it passes the value so i can work with that to remove the corresponding xml node. (using XPath)
XmlDocument XMLDoc = new XmlDocument();
XMLDoc.Load(file);
XPathNavigator nav = XMLDoc.CreateNavigator();
var node = nav.SelectSingleNode("/root/name['" + ??? + "']");
node.DeleteSelf();
XMLDoc.Save(file);
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.
The name gets displayed in the 1ste colum of the datagrid, where in the 2nd colum there is a buttoncolumn with delete button.
How exactly can i use xpath and navigate to the current node lets say with test id="0" and delete it (including name)?
Its unclear how i can say to this method what row he has to delete exactly.
[Code]...
This does delete the first item, but offcourse crashes on the second. How an i make this into something variable that is bound depending on what button i press in my datagrid?
I have a treeview with four levels; parent, child, grandchild, great-grandchild. My selectednode is at the grandchild level.
What I'm trying to do is to create a new "Treeview" at the grandchild - NO, I dont wnat to create a new node to the "selectednode" (grandchild). So it should be somelike this:
I want to delete location path using parameter textbox .. example : I enter name of location path in the texbox when i click button delete then location path in web config will be remove..
I have a added a webform user control in my master page. This user control contains an ASP.NET tree view control. How can I get its node click event in my default.aspx which in implemented master page. I have to show some text on default.aspx page against that selected node ID.
I've a used a tree view which shows the category as parent node and subcategory as child node.I've taken the data from mysql database using sqldatasource. But i want get the selected value of the tree node which i would click. Than use that value in a sql query to delete or update the node.I dont know how to get the value of a node which is clicked.
I want to delete location path using parameter textbox and allow user ..
example :
location path = textbox1 allow user = textbox2
explanation : i enter name of location path in the texbox1 and allow user in the texbox2, when i click button delete then location path based on parameter textbox1 and textbox2 in web config will be remove..
But i have a issue suppose i have a tree of State with nodes CA,WA,AK,AZ. When i select CA its becomes Marron and when i select WA its becomes Marron but CA becomes normal. I want all(which are selected) indivually are Marron.
While populating the tree-view I have a requirement to bind the one particular level with a different colour. So, I am binding it as below
foreach (DataRow row in dr.GetChildRows("rsParentChild")) { TreeNode cChild; if (row["NAME"].ToString() != "") { if (row["Level"].ToString().Trim() == "4") { string strColor = "DarkOrange"; string fname = "<font id=" + row["NAME"].ToString() + " color ='" + strColor + "'>" + row["NAME"].ToString() + "</font>"; cChild = new TreeNode(fname, row["ID"].ToString()); } }
Now when the tree view loads, the required level 4 nodes are populated in DarkOrange. But, when any node is selected the backcolour changes as #6f9dd9 as per the style specified in the markup. But the fore-colour does not change.
Suppose I have a treeview, where each treenode contains an id for a different set of user controls. When the user clicks a node, these controls should be loaded to the page. As I understand the ASP page life cycle, dynamic controls should be added in the initialization stage, and postback events will fire later on.
So if the treeview click event happens after I need to add my controls, how do I dynamically add controls based on user postback events?
Edit: I tried the ArronLS:
What I did was add the node value to the session array, and use that when I do the init to choose which form elements to load to the controls of a placeholder control. On the treeview click event, I update the node in the session array, clear the old form elements in the placeholder, and add the new form elements to the controls. When the page is loaded again, it should now find the node at init time, so viewstate problems would be circumvented.
Now I haven't fully tested this yet, but there was another similar post that talks about the problems that might result with the viewstate. They suggest a solution that polls the Request[] part of the context (in their case the dropbox) within the Init control, manually handling some of the postback functionality.
My new question is how to I access the selected node in the treeview using the Request array?
Im using an asp.net treeview control and i managed to get code from these forums so that when i select a node no postback is done but i can access the selected node in my C# code behind pages by using javascript.
It works fine i can get the selected node by saying:
TreeNode t = TreeView1.SelectedNode;
and then displaying it to a label on an on click event of a button:
Label1.Text = t.Text;
But what i really need is to either display the node selected to a label (or textbox) or when a node is selected it needs to be highlighted so that the end user knows the option chosen is selected.
i ve used the following code to avoid postback and selected node style for treeview by using this im able to avoid postback but im not able to set selected node style.
I have a treeview control where I am dynamically selecting a node depending on user interaction. when a node is selected I want to be able to have the scrollbar go to the location of that selected node in the tree. The scrollbar is simply made by overflow:auto in the div tag where the treeview is located.
my requirement is to get the result in gridview based on the treeview node selection using javascript i.e. client scripting. Currently the same can achieve using server side scripting, but i want with out postback and without using selectednodeindexchanged event.
I don't want to use Sessions to handle each click event inside treeview selected node changed.Secondly, if you suggest me to use treenode.SelectedValue then I would say my values are dyanmically generated.Everytime a node a clicked, the selected node value is sent in the next request xml to get response and xml schema is different for each click. How do I handle this each click event other than using session variables. I thought of using Request.Item (and integrating with URL redirect property) but I don't want to use that.
Am new to asp.net.I am creating a site using asp.net(C#), in master page i have treeview control, when i select a item i navigate to url. But selected node is lost, it reset itself, loosing state.
I am having treeview with checkbox and 1 submit button it is taking values from database. Now if i check the checkbox and click the submit button it should display the selected node in the textbox..... Here is my treeview code
public void Load_tree() { DataSet PrSet = PDataset("SELECT * FROM tbl_saleschannelhierarchyconfig"); TreeView1.Nodes.Clear(); foreach (DataRow dr in PrSet.Tables[0].Rows) {
