Data Controls :: Bind DataGridView For Particular Childnode (ID) When Select / Click Any Particular Child Node
Mar 31, 2014
There are multiple child nodes coming from Database in Treeview. Also, there is a DataGridview.
I want that when I select/click any of the child node from TreeView, it should show the related data(of selected child node) in DataGridview from Database on "Page Load".
My current code is below, which only binds all the data in DataGridview and Treeview from Database:
i want to create one treeview dynamically which will have child node and sub child node.for this i am getting my treeview value from the table with below column:Id,Name,Parent,IsActivewhere main parent nodes parent id will be 0 and then all other records parent id would be related id. the table structure would look
I have a treeview, the TreeNode's NavigateUrl have a javascript function, after i click the "Item 1", it shows a message box ("1"), but it does not expand the child node, what can i do?
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.
i have two table. one of them is having car types with unlimited sub categories. the other table is having details about these cars. i want to show you the tables in an example.
I am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
I have no idea to use which code. I need to retrieve the selected item's Price, Name & ProductID in to the next page in table that should later be redirected to payment gateway.
I am binding Gridview using json (first Gridview),which have some column with linkbutton. I want to bind other gridview(second Gridview) using json on click of Linkbutton inside first gridview . how to fire json on linkbutton click event ?
GridView gvchild = e.Row.FindControl("gvOrders") as GridView; drplist = gvchild.FindControl("drp1") as DropDownList; // den also same error object reference not set to an instance of an obj
I have a FormView with an EditTemplate.And the EditTemplate contains an ascx control:
<asp:FormView ID="fvTicketUpdate" runat="server"
[code]...
The contents of the ascx control has TextBox and DropDownList controls binding to the results of the FormView's ObjectDataSource through Text='<%# Eval("field1") %>'and SelectedValue='<%# Eval("field2") %>'.This works fine and I have been building all of my front end pieces like this as <asp:Panels> rendering as FieldSets that go 100% across the screen.And we call these areas "strips" accross the screen.But now I've run into a problem.One TextBox and one DropDown bind fine to a Ticket Object.But the DropDownList that works has its <asp:ListItems> hardcoded before hand.Now I have DropDownList that gets populated through a WebService in the ascx's code behind like this:
public partial class UserControls_FormControls_PntipUpdtFaaInfo : System.Web.UI.UserControl { protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack)
[code]...
The Problem I think is the FormView is trying to do its Bind to the objectDataSource before its child ascx control is loaded in the Edit Template.And I am getting this error:
Databinding methods such as Eval(),XPath(),and Bind() can only be used in the context of a databound control.Meaning that the control must already be databound to bind the selectedValue to a Property of the TicketObject.Is there an easy way to force the order of loading to make the PntipUpdtFaaInfo control load and have its Page_Load execute and bind ddlEquip before the FormView does its first dataBind and executing its Evals?Otherwise I have to take out the eval on the ddlEquip SelectedValue attribute and go to the Parent Page and hack and force everything to happen when it needs to.This layout has worked out well for me.All of the ascx area strips across the screen share the same Validation Summary for example.It allows me to think about one section at a time and the Properties to the Business Obect and CRUD methods as I go.But this is a big brick wall I've hit.
I am trying to select data with Linq and bind to a DDL. The custid field allows duplicates in this table, but I only want unique values in the ddl. I tried the following code:
[Code]....
The use of "Select Customer.CustID", with or without the Distinct, causes this runtime error. CustID is a valid field in the table, and it shows up in intellinsense and compiles. If I just Select Customer, the error goes away, but Distinct doesn't know to look for distinct custid's.
DataBinding: 'System.String' does not contain a property with the name 'CustID'.
i am having Nested Gridview and from the child Grid i have to select the checkbox to retrieve the id's by iterating the child grid and that to on the Button Clik which is outside the Gridview.
I had populated data in TreeView control. How will I drag a particular child node from a parent node and drop the dragged one to a DIV or any portion, using JQUERY ? I know in jquery, there are methods "draggable" and "droppable" to make this possible. But I want to drag a particular child node and drop it.
Or atleast How to fetch the text/id of a particular child node using jquery ? I hope I can drag,if I can fetch the child node
On our site we have a top menu, and a side menu. Other than using the same sitemap, they don't have any other relationship.
On the top menu, we only show the top links, with 0 child nodes, which is what we want.
On the side menu however, we want to show all the child pages when someone hovers over the main links. Some have up to 12 child nodes, and some only 1.
Our challenge is hiding a couple of specific pages from that menu.
An example is a "thanks for contacting us" page which is under the main "contact us" page. Otherwise, a person can hover over the contact page link and see the "thanks" page as a link - and we don't want people going directly to the thanks page. So, we want just "Contact" to show in that menu, no matter where a visitor is in the site.
I have tried a couple of solutions but they haven't worked. Is there an easier way to hide them?

I create a site map for my site but it only works three levels deep and I need at least six. How can I do that? Every time I add a child node under "Water Filters, Desalinators or Micropur" the sitemap doesn't show the child node. Until now my sitemap only works three levels deep: Home > Products > Water Filters But I need this: Home > Products > Water Filters > Katadyn > Personal Use > Pocket Turbo 1. This is my sitemap configuration:
