Forms Data Controls :: Manage A Datagrid Within Another?
Dec 28, 2010
I have a table in my database with three fields: COURSE_ID, PERC, DATE.I need to display sets of rows based on the date, the number of rows in every set will be known at run time, the same as the number of sets, so I was thinking about adding two buttons (one to add a set and another to add rows in that set)
I know that working with GridViews will do, but do not know how exactly, maybe one gridview for the sets and a second gridview (inside the first one) for the rows inside the sets.
I know how to handle the filtering of the grid (create a criteria and set to rowfilter of the dataview) But, I dont know how to get the value of the column of the selected row.
I have Datagrid , i want to clcik on row and get data in textbox , but my textbox is FreeTextBox control,i tried to use javascript but work for asp.net control not working for freetext box control, how i can capture this code is sample code but it work for asp.net control but not working for my freetextbox
Simply put... I want to duplicate the example found at this link, in VB.net rather than C#.

I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.
I have 2 datagrid (using .net 1.1). I need to access column of second grid ( i need to make a column of second grid as disabled) when i click "Cancel" link button in First Grid. How can this be done?
I have "Order" object with Columns Ticket,OTP and CustomerName etc.Intially on DataGrid, I'm binding Ticket only , when user clicks on "Column Chooser" button, another windows appears to pickup CustomerName,OTP columns to add specified column dynamically on Datagrid. Environment : Asp.net ,C# with Object Data source
Public Class Order { publc void Order() { } public string Ticket { get { return this.strTicket; } set { this.strTicket = value; } } public string OtpNumber { get { return this.strOtpNumber; } set { this.strOtpNumber = value; } } public string CustomerName { get { return this.strCustomer; } set { this.strCustomer = value; } } } }

On my web page I'm trying to manage a tabular control of some kind that supports inserting. The data will be inserted locally on the page, with no connection to any kind of DB.

I'm looking for a steer on how to go about running stored procs efficiently.
I have a current requirement to populate a control, so I have all the specific data i.e the parameter value I need to pass and the control I want to populate, plus generic data such as SqlConnection etc.
I'd like to be able to call, say, "MyStoredProc". MyStoredProc would contain all the necessary information to run the proc, but then pass onto a method, say, GetSpData, which contained all the generic stuff about running stored procs.
Then when setting up MyStoredProc2 I could do without repeating a lot of the original function
Im I barking up the wrong tree or is there an efficient way of managing this kind of situation.
I have a datagridview control that I'm using to display cache data to the end used on a web form. The issue that I'm having is that every time I re-run the application, and the cache data is re-generated... it loads duplicate data that's being displayed to the end user. I can't seem to figure out how to keep this from happening.
What I would like to have happen is that only unique data rows be returned and cached for the end user. Unless there are new data rows on the database that needs to be included in the cache data results...the previous data results should not be duplicated. I've tried to change a few properties on the datagridview control, but nothing seem to keep this from happening.
I have a problem there that is i want to insert the data in database from datagrid but i have various controls like textbox and datalist in grid view inside datagrid now i want to insert the values of that text box and datalist in database how i can do this.
I have to include a button 'del' in my datagrid. I already have two buttons 'savechanges' and 'cancel'. how to include one more option saying DEL in the same datagrid?
I am new to asp.net programming!!I have a datGrid Control on my web page and am able to load the data into the datagridafter loading the data to the grid , when i select a row from the grid I am loading those values into the text boxes that are present on Now what the problem , if my grid has say 20 records and having the vertical scroll to view all the 20 rows.
When i want to show the data of the 16 row ( say in this instance ) after scrolling the down for the 16 row ...after selecting the 16 row the data is getting posted to the corresponding textboxes ,but the here the data is getting scrolled to top after selection and not able to see the seleted row , for this i need to scroll down again!!!
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load If Not IsPostBack() Then LoadDataGrid1() End If End Sub Private Sub LoadDataGrid1() Dim tmpds As New DataSet Dim tmpdv As New DataView tmpds = boNews.getSelectedList(1, Format(Now(), "yyyy/MM/dd")) ' tmpds = boNews.getTodaysList(Format(Now(), "yyyy/MM/dd")) tmpdv = New DataView(tmpds.Tables(0)) DataGrid1.DataSource = tmpdv DataGrid1.DataBind() End Sub
I notice that the DataGrid control has properties for "SelectedRow". What I don't understand is how to select one. Nothing looks clickable when I'm viewing my datagrid populated with data, it just looks like a static table of information.I need two things to happen. 1, as they move their cursor over the rows, I need the row to highlight. 2, when they click a row, I need to fire an event so I can run an SQL query based on the row they clicked?2 questions.1. Is it possible for a DataGrid to do this.2. If it's not possible, what should I be using instead?
