Is there any way i can make all the nodes of the treeview checked by default other than looping through the nodes and setting each node property Checked=true; I dont want to unnecassary loop through the node collection to set each node property. There should be easy way of doing this by setting simple property for the entire treeview. Oh i am using the RadTreeView, I dont have the

This thread is basically a continuation from my last post. I have a website that uses a TreeView Control. Each TreeNode represents a virtual directory and I wish for the user to be able to create a new Node/Virtual Directory. This site is for family photos. Each family member has their own node with a Child Node called "Albums". Within this "Albums" node, a family member can have as many Nodes/Virtual Directory as they want with each Node/Virtual Directory containing images.Each Virtual Directory path is stored in a Database. So essentially, I'm trying to create my own photo album. My question is....how do I allow a user to create a new Node/Virtual Directory (they don't know that a VD is being created...only a Node).

View 1 RepliesI´m using a template from microsoft´s webdev.
I have a nested masterpage and in the childpage of the second master I have a treeview. Now I want to change appearence of the nodes in it (like the color), and I´m not able to do that. It doesn´t say anywhere if there´s a section of the css stylesheet that´s being applied.
I have this code:
Code:
Dim obj1 As New TreeNode
obj1.Value = 1
obj1.Text = "Level" & obj1.Value
Dim obj2 As New TreeNode
obj2.Value = 2
obj2.Text = "Level" & obj2.Value
[Code]...
Can I somehow create a function that creates the nodes instead of I need to make Dim ... each time? If I have 300 nodes this is not a good solution.
I have tried something like this but it doesn't work:
Code:
Function CreateObj(ByVal no As Integer, ByVal name As String, ByVal obj As TreeNode) As TreeNode
obj.Text = "Level" & no
obj.Value = no
treeview1.Nodes.Add(obj)
Return obj
End Function
I've managed to render TreeView using custom made Hierarchical Datasource based on Linq queries on self referencing table. Rendered output looks well but... Every Node in NodeCollection has the same index = 0. Therefore when I click on any collapse button - the whole tree Collapses. In generated html every node has the same id = MainContent_TreeView1n0 I suppose n0 should increment to n1 n2 n3 and so on.
View 5 Replies I have a datagrid which is bound to a stored procedure in the code behind. This works fine. But the datagrid contains a checkbox which I need to be default checked. First I didn't bind the checkbox and just used:
<ItemTemplate> <asp:CheckBox ID="chkSelection" Runat="server" Checked= "true" /> </ItemTemplate>
but they show as unchecked. then bound it using:

Suppose parent dropdown is car (Values are car1, car2, car3)and its child is color(for car1 R Y G B, For car2 R Yand for car3 G B).Now on selection of car2 R and Y will appear and select R, then again made the change on car and select car3 then again select is comiing with G and B and select B.
Now if I select again in car, car1 then the child is populating with the values of car1 but it takes the B as a default value as it was previously selected and also present for car1 too.This case is only happen. on select of child value which is availble for both parent selection.
I have a GridView and Details view inside an updatepanel. When I set the page's default button to a link button in the Gridview, it works fine. Any subsequent attempt to change the default button to another link button(edit,update,etc) in the Details View doesn't work.
View 4 RepliesI have been using the toolkit for 3 years and update it as new releases come out but recently (after the 10/09 update) whenever I try to use the default styles with a control they don't display. For instance, the calendar extender and the validator callout extender are missing their default styles. Well only part of that statement is true. With the validator callout the ! image displays but no other style is present.
what to do or what could be going on? I have cleared out my IE cache, history, cookies and still experience it.

I have a user input form with a cascading dropdown. The code is:
[Code]....
Once the user submits the form, it goes into a temporary table, pending admin approval. On the approval page, I display a GridView of all pending records. Is it possible to use a CascadingDropDown in the GridView, with each Dropdown set to the value stored in the database for that specific record?
If I can't do this with a gridview, how about a dynamic ASP table?

View 2 RepliesUsually my Modal popup extender is center by default. However, I have a modal popup that is not center - the modal popup is located on the right lower side of the screen. I have a CSS class for my website that I really dont want to start tracking to see if it is causing my problem (In fact I am pretty sure thats the cause of the problem). So I was thinking...
Is there anyway I can manipulate the modal popup position through the CSS. For instance:

The above is not working, it doesn't do anything to manipulate the width of my background and the position of the modal popup.
I have a form in which I have a gridview with a LinkButton culumn in which when the user clciks a modal popup extender shows up. In the modalpopup I have a dropdownlist which is filled from DB in code behind. but when the user clicks on Add button in modalpopup panel, the selected value of the dropdownliast is always its default value.
[Code]....
here is my code behind:
[Code]....
I traced my code behind, the fillData() which fills up dropDownList is called only once in page load's first time.
PS. I understood the problem exists only when the modal is poped up by linkbutton click of gridview. when It is poped up by a button outside the grid it workes fine.
I've this problem, how can I set the default value for drop down list filled with cascading.
I can't catch the event that came after cascading to set the default value and I can't call any control in this function:
"AjaxControlToolkit.CascadingDropDownNameValue[]"
I've passed the Drop down list as a session and the default value in session
When I call the session of "Drop Down List" the session value Is NULL in this function:
"AjaxControlToolkit.CascadingDropDownNameValue[]"

I have a following issue (it's only happening in Internet Explorer).
I add callback to a page in the old-fashioned way -> Page.ClientScript.RegisterClientScriptBlock(...)
The scenario is: 1) The default page is being loaded. On Page_OnLoad it assigns a NULL to some session key. Let's call it Control -> Session["Control"] = null;
2) User presses a button and gets redirected to a next page (let's call it NextPage.aspx) using javascript event -> window.location.assign(....) (also tried .href = ... - no help)
3) The NextPage.aspx assigns some value to Session["Control"] on Page_OnLoad
5) User clicks a button on the NextPage.aspx and a callback request is being sent to a server....
TA DA!!! The interesting part:
6) Along with the request to the NextPage.aspx another request is being sent to the default page.
7) The only response is being recieved by a client is a response from the NextPage.aspx BUT since the code on the default page is being executed it puts null to the Session["Control"] which screws all my following scenario. the default page doesn't recognize the request as a callback? so if(IsCallback) {} doesn't help....
I believe it's not a code issue since as I wrote above it works in development environment,but I have no clue what can 'cause it to fail in production and only in IE...
At least what to start to look at... and I have Helicon's ISAPI Rewrite installed on the production server. It doesn't seem to be the cause but who knows....
Correction
if I do not assign window.location and just add a link to the NextPage.aspx and click it manualy after callback ended it still sends extra request to the default page. if I click the link before I initialize callback it works fine without extra request.
