Forms Data Controls :: How To Bind Hierarchy Grids From Ojects Or Lists
Aug 14, 2010
i have Successfully binded the Schedular from Objects and its looking Good and the Following code has done that.i am using the Telerik Grid , but the implementation to the grid is the same as the Gridview. What i need is a guidance on how to bind hierachy grids from ojects or lists
[Code]....
Now with the same results i want to bind a Hierachy Grid as it Shows in my attached image. I am using EAE that means the is no Fixed Column name, so the Binding of the Grid Should be Dynamically.

I have the following sql table which contains menu (website menu) data.
Table Name: MenuItems Columns: Id, MenuId, ParentMenuItemId, Text.
My goal is to bind a DDL according to the following hierarchy (example):
Id: 1, MenuId: 1, ParentMenuItemId: -1, Text: 'One'
Id: 2, MenuId: 1, ParentMenuItemId: 1, Text: 'Two'
Id: 3, MenuId: 1, ParentMenuItemId: 1, Text: 'Three'
Id: 4, MenuId: 1, ParentMenuItemId: 2, Text: 'Four'
Id: 5, MenuId: 1, ParentMenuItemId: 4, Text: 'Five'
Requested result in DDL:
One
-- Two
---- Four
------ Five
-- Three
I think it should contain 'WITH' SQL command.
Note: I'm using C#.

I have tried to use a GridView and DataGrid and the binding works but there isn't a grid that displays. Not even the header row.The web page
[Code]....
The code that loads the gridThis is called first to get the XML and load into a text box
[Code]....
This is called after to bind to gridview
[Code]....
So while in DEBUG mode I put a break point on the DataBind() and got the following:
?gvData.DataSource
Count = 340

I am using C#, Object Data Source, formview and a BLL. I have two drop down lists and two data sources. One populates the other. Drop down list #1 populates Drop Down list # 2 based on its selection . Drop down list # 1 is populated with DataSource #1. Forview is using DataSource #3 to send the ietms. When I add: SelectedValue='<%#Bind("Make_ID") %>', I get the error below:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control
I have seen a solution online but it is using LINQ and I am not familiar with it. I need to find the selected value of the drop down lists.

I have a web app that uses a master page with mulitple user controls on each content page. Most of the content pages have grids (telerik) that present data, with HTML tables that are created dynamically from a database. I write the load the HTML dynamically into a label. We also are loading a YouTube snippet that is set in HTML and we are get the most recent video within a playlist.
My challenge is that the pages are loading slow. Very slow. There is consistent traffic to the main site with two other sub domains for management and they all utilize one database (shared within one instance of about 20 databases) on a shared web hosting server.
My goal is to determine if the User Controls, Data Access, WebServer, or SQL Instance is slowing the site (all 3 domains).
The site is running good with about 400 avg daily users, however, the site is now averaging about 1300+ daily users and i'm not sure if a Dedicated Server w/dedicated SQL Instance will resolve the challenges we are facing.

I have 3 nested grids as Parent/Child/GrandChild and I have assigned SqlDataSources to all the grids at declaration time. I place the SqlDataSource next to each grid as follows.
<GridView>..</GridView><SqlDataSource>..</SqlDataSource>
Because of this I am not doing anything in RowDataBound(...) event. But I used the RowCreated(..)event of Parent and Child grids to access session (Please look at the select statements of Child/GrandChild grids).
Parent grid's RowCreated(..) event puts the value in the session which is used by Child grid. Child grid's RowCreated(..) event puts the value in the session which is used by Grand Child grid.
GrandChild grid has paging enabled and whenever I click on page index, Child and GrandChild grids goes blank. Parent gird doesn't go blank because its select statement doesn't take any "select parameters".
how to overcome this problem. I am attaching .aspx and .aspx.cs files

Here I store the hierarchy data for the Organosation. Under_Level_ID denotes under which Level_ID the current Level is lying. e.g. for Branch the hierarchy in above table will be likeHO-->REGION-->Branch & for ZONE the hierarchy will be same as branch. Now my problem is I need all the hierarchy below a given Level. i.e. if am passing 132 as level then the SP should return me all the hierarchy elements lik Zone, Branch, fgfgfhf, Cluster,
CREATE TABLE [dbo].[T_LEVEL_MASTER](
[Level_Id] [numeric](18, 0) IDENTITY(1,1) NOT NULL,
[Org_Id] [numeric](18, 0) NOT NULL,
[Level_Desc] [varchar](100) NULL,
[RM_SB] [varchar](50) NULL,
[Under_Level_Id] [numeric](18, 0) NULL,
CONSTRAINT [PK_T_LEVEL_MASTER] PRIMARY KEY CLUSTERED
(
[Level_Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

I have a number of dropdown lists which are populated from a database. They load depending on what the previous dropdown selection was so for example if the system was car based and I had chosen Ford then the next dropdown list would populate all cars made only by Ford. What I'm wanting to do is add a select all to one of the dropdown lists. Does anyone know how this would be done?

I have 2 drop downlists 1 gets the User hits my sql database and pulls back all my users in the database. I have post back on. The second drop down brings back all the account numbers for the user that is selected in the first drop downlist I have that post back on also.
My gridview then uses those 2 dropdownlists to populate for that user and that account number selected.
Now for the problem.
User Albert is in the drop down when page is loaded because its sorts by name the first account number for albert is in the 2nd drop down and the gridview works on page load for albert and account number 1 i can select account number 2 and the gridview changes.
I then switch user to Bill and it populates the 2nd drop down with Bill's account numbers however my gridview at this point is still showing alberts account information. I have to take drop down 2 and select another account say account 2 then my gridview displays bill's account 2 information i can then switch back to account 1 for bill and see that account information.
What do I need to do so that my gridview will populate when the first dropdown is changed to match the 2 new values?
Here is my code

I'm trying to create a page with multiple fields to be used as parameters for filtering a GridView. I'm using a combination of two asp:dropdown lists and two check boxes. When I select a value in one ddl, I want to clear the value in the other ddl. I was trying to use the event "onTextChanged" but that doesn't seem to fire off on the client side and I cannot seem to find any event for an asp:ddl or asp:checkbox or asp:radio button that fires off on the client side.
Are there events, like onClientClick for asp:button, that fire on the client side for these controls when a selected value is changed or when the user clicks on them? or do I need to use html controls instead?

I need to make a large Ebay-style list of listings (think of the page that comes up when you search for something in Ebay, with a photo, title, one-line description, price, that's paged, and sortable). My limited experience with DataGrids in the past always resulted in what felt like a sluggish page to me, but I'm not sure if it would have been faster if I had pieced it together with a data reader instead.So I'm wondering before I even get started, what is the fastest / most efficient way to retrieve and manage this data.Is it more efficient at runtime to use a DataGrid, or to write the paging and sorting in more manually and use a DataReader, or another way?Ebay manages to get thousands of listings to display very quickly, but they've obviously got a lot of manpower to squeeze every last bit of performance they can out of the site, and good high-powered servers.

I'm using VWD with a database back end. I have a list of teams which are marked off by league, level, division, teamid and then using gridview for the list of players per teams.I've got the drop downs working correctly but running into a little snag and that is on the auto postback.When I only have one option come up in a list, i obviously don't change that list and thus it doesn't change the next drop down because there is no post back. is there a way to use a "header" value?

I am using a dataset control and I have 5 dropdown lists in which their content depends on what item is selected in each dropdown list.
I know I can populate the lists with 5 different queries taking the variables from each list but I am thinking there must be a better way.
Is there a way to populate each list with one query that takes the distinct items from each column returned without looping through the entire recordset?

To Start with, I am new to .NET. So I am not refer to the right word, but I'll write up whatever I can.
Basically I have 3 input fields and then a search field.
When I hit the Search field, based on the 3 inputs, it needs to get the DataSet and fill it in the ListView.
I believe it is doing it. But when I added the DataPager, it lists only the first 10 rows, even if hit NEXT
Here is the code ib the .aspx page to populate the ListView
asp:ListView
ID="FISIItemsList"
ItemPlaceHolderID="ListFISIItems"
Since the NEXT button is not working, I thought of Adding the DataSet to a Properties. The and getting it back.So I did something like
public
DataSet
dsFISIItems[code]....
Even this doesn't work.
In simple terms, > After the 3 input fields are filled out, when a "Search" Button is hit, it should go and pick the list of items based on that criteria
> The result dataset needs to be binded to the ListView
> Next, the DataPager control should be paging. But it is not paging.
When I hit the next, it lists only the first 10 items repeatedly.

I have a 'Read More' Button attached to the repeater control, and when it is clicked, the list currently displayed
should be remained and the new repeater list should be appended to the bottom of the currently displayed list.
And the 'Read More' Button should now be located below the newly created repeater list and it can be clicked again and the process above continues.

I need to develop a custom data-bound control which will contain, few text-boxes, drop-down lists, labels, and other standard web-server controls. And, I want to be able to load this control from a web page on button click. When the user enters any data to any of its child controls, i should be able to save, and also retrieve when the data-bound control is loaded again. Also, the data in the child control should retain their value on postback. What approach should i follow?
