Right side page takes long time to load. so i want to let user know that its still loading. so when ever user clicks on the tree node for any page,i will to show him a image control with a text saying 'please wait.. its loading'. Sample code will be greate as i need to do this by end of day today.
View 3 RepliesIm 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.
<asp:LinkButton CssClass="button" ID="btnApply" runat="server" OnClick="btnApply_Click()" OnClientClick="Apply1('btnApply')" >
hi ihave this functin in .vb file
Protected Sub btnApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnApply.Click
end sub
and javascript function also in aspx
function ApplySummerization(id)
{
alert("hai");
}

View 5 RepliesI have a function in Code Behind, Can any one let me know "How would I call this function using javascript"?
View 4 RepliesI don't need to run the function every time the page loads!!
But, I would like to have the control when the function is to be called.
The only way I thought of is calling my function with OnLoad in the body tag and having a hidden field to be checked and then run the script accordingly.
e.g:
<body onload="ScrollToView();">
Is there a better way? For example, running the function from Page_InitComplete handler?
in aspx:
function checkFunction(no,name){
}
in cs:
string test_name ="hello";
StringBuilder Strname=new StringBuilder();
Strname.AppendLine("<td ><input type=checkbox onclick='checkFunction("+no+","+test_name+");' runat='server' name='checkbox_name' value='XX'</td>");
when i call the checkFunction(), i can't pass the 2 argument as there is error.

protected void clickSave(object sender, EventArgs e){
ClientScript.RegisterStartupScript(this.GetType(), "MyScript", "function_me( "" + Strname + "");", true);
}
I have javascript function like below
function SetScrollEvent() {
      window.scrollTo(0, document.body.scrollHeight);

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">

On button click i want to call javascript.
I am trying to extend the TreeView and TreeNode class and use it in an .aspx page. My development environment is VS 2005. I put the following code inside of a single .cs file in my App_Code folder:
public class MyTreeview : TreeView {
protected override void TreeNode CreateNode() { return new MyTreeNode(); }
}
public class MyTreeNode: TreeNode { public MyTreeNode():base(){} }
I want to now use my inherited Node and TreeView in my .aspx file. I have the following directive, which is throwing an error -> File is in the special directory App_Code which is not allowed. I tried putting everything into an .ascx file, but I think I am not specifying the class and inheritance directives correctly.

I have this working in several pages in my site but in one page it wont work!
this is the hierarchyof the page.
I have a treeview in a div,in an asp:panel, in an updatepanel in a user control. the panel is shown/hidden using the ajax modalpopupextender.
this user control is placed in a content page (using a master page).
Now that you got the above, I'll let you know what ive tried already.
I tried doing this:(which works perfectly when the treeview is placed simply in an aspx page)

tried using also :

Basically i kept playing around with it trying different ways but seems like the selected node is just not visible even though i call this JS function after i have selected the Node in code behind.
I´m using a treenode´s selected node´s value to filter a an accessdatasource which populates a gridview.However when I press the "edit" button in the gridview, I guess the node is undselected because the gridview gets emptied. When I reselect the node, the gridview displays the filtered records, and the one being edited is in edited mode.So I´d like to keep the node selected. Not only because of the above, but also so the user can see what he is editing.Fuga.edit: When I remove the filtering from the accessdatasource init event, the gridview diplays all records, but the worng one is being edited. I guess it´s the one with the same index as the filtered record. So, visual studio gets the index and then reloads the data and applies the index on the reloaded data!?
