Forms Data Controls :: Get All The Checked Child Nodes Belongs To Specific Parent?
Dec 29, 2010
I have a treeview and all nodes are check box, when user clicks on a button, how can I get all the checked child nodes belongs to specific parent? I wanna something better...
when i check Treenode with Text='Velocity', all the three child nodes will get checked. I want only the count of child checked nodes. How can be it done.
I'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
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).
I have an xml file like this.I wnat to display a gridview when i click on the EX_ACK_PEN i want to display a gridview with fields Tag,Value,Name.How can i get the childnode values .
I have a treeview in my .aspx: <asp:TreeView ID="tvDocCatAndType" runat="server" /> Not much else going on in the page -- two <asp:LinkButtons> and one <asp:Label>; the page is a child of a master page, so these controls are within a <asp:Content> control. I populate the treeview in code -- just 3 node levels, including the root node. All nodes have checkboxes, and I initialize all node.Checked to true. I have some Javascript to do the usual check/uncheck up and down the tree as parent and child node checkboxes are toggled.
No matter how many checkboxes I clear in the UI, on postback every single node has node.Checked = true regardless of the state of the checkbox in the UI. This is not the first time I've used a treeview, but I've never had this problem before. I created this page by light adaptation of an earlier project that works fine.
I am using a collapsible child gridview inside a parent gridview. When I click on the expand image, the data to displayed is put up correctly, however when I make some changes in the child gridview, they seem to be lost!! That is, the changes do not get reflected in the database.
I have created a search page for web application that will allow a user to search the database based upon employee name or supervisor name. It is a multiple table database that is linked together by an unique employee number column, primary key in people and foreign key in supervisor. I have a parent/ child datalist used to display the record. When searching by the employee name it will return the record correctly if there is a record found. However, if I search by supervisor name and there is no match for the supervisor name, it will return all the records and create the parent datalist with all the employee details there, but the child datalist with the supervisor information is not display as there is no record with that supervisor name.
since APS.Net 4.0 I have a curious problem with an event.
There is a FormView and inside of the EditItem there is a GridView. In the Footer of the GridView I put Controls for inserting records.
But when I fire a markup defined RowCommand of that GridView then the same event is getting fired for the Parent FormView. First I had 'Insert' as the CommandName and so I was getting the Error that my FormView had to be in insert mode to insert a record. Then I changed the RowCommand of the GridView to 'xxx' and I got also the RowCommand 'xxx' at the RowCommand eventhandler of the Parent FormView.
The project was migrated from .Net 3.5 a few days ago, but nothing was manually changed in the code/markup. And the problem was not there with the "old" framework.

Of course, I could simply change the CommanName of the LinkButton e.g. to 'InsertChild' but I would like to know:
I am currently trying to figure out the best way to handle a data formatting issue. I have a stored procedure that pulls back basically all the data I need, but using a gridview doesn't really give me what I need.
For example...currently the gridview displays data like:
I have a requirement where I need to show the data in parent/child form .For Example - Lets says we have have customers and each customers can have multiple orders.I need to display it like this -
Cust1 Info about the customer Gridview (showing all the orders for the cust1) Cust2 Info about the customer Gridview (showing all the orders for the cust2)
Within the EditItemTemplate and InsertItemTemplate I have a cell that has a textbox and a button.
When the button is clicked a popup window is shown, where the user can upload a picture. The name of the uploaded picture is retrieved.
Now I want to send that picture name back to the textbox within the listviews EditItemTemplate or/and InsertItemTemplate (that is ofcourse one at a time depending on what the user is doing, inserting or editing a row).
The code I have written so far looks like this. The below code has been abbreviated
[Code]....
The code behind looks like this (also abbreviated). Actually I don't think the code behind is needed, since its mainly javascript from the popup window (child page), but nevertheless here it goes.
[Code]....
And at last the child page / popup page.
Well there is not anything to see here, cause I'm using the Telerik RAD upload control, which is doing everything for me.
However the line below may be of interest. Here I'm taking the name of the uploaded file (picture) and printing it to a label.
Simple and blunt: my cascading dropdownlists clear when a postback occurs. Does anyone know a quick way around that?For more information, read on...
I have 5 dropdown lists that define a training class location and line of business: Site, Parent Client, Client, Program, Project I'm trying to build cascading dropdownlists that can work from any direction (i.e. select a site and all other lists are filtered by site...select a project and all other dropdown lists are filtered by project). I've built the SQL Select statement behind the lists that filters (accurately).
I am working in Asp.net 4.5. I need to create a grid as like below, I am struggling to make the merging cells and make it as multi header row by combining all the cells...
Is there any sample to make gridview like this.... I need to do this on codebehind. I browse through the internet and found couple of sample but those are not having the header like i posted. I am little confused about making full header as merged cells....
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?
