Forms Data Controls :: Highliting Row In DataGrid?
Mar 24, 2011
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?
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; } } } }
I had called the data from query to data table and now i have a gridview in which i am using one datalist and 2 text boxes and and reming coloumns are bounded iahve to assiaign them values which datatable have either null or any value.
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 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 have a datagrid with check box that allows users select all rows in the datagrid. However, when the user check the check box and the page postback, the data in one of the columns disappears.
I have a datagrid which pulls data from a single database table to display it. However, this database table also contains information on the thumbnail URL for each record, and I would like to display the thumbnails for each record in the 1st column of the datagrid.
At present I have added the following to my datagrid:
[Code]....
So I presume the main challenge now is to set the Thumbnail.ImageUrl property to the correct file path in the VB.NET code. But how do I do this for each record? I am using a function to retrieve data for the gridview, which is based on the following:
I am having an issue with a simple databind to a datagrid. What happens is that for some reason, the first character of the data going into the 4th column is getting placed at the end of the data in the third column; but only on the first row. Here is an example of what I mean:
Form ID Employee No Associate Name Start Date End Date Form Status 1234 5000187 Stan Marsh1 1/16/2010 11/30/2010 Approved 1234 5000187 Eric Cartman 11/16/2010 11/30/2010 Approved 1234 5000187 Kyle Broflovski 11/16/2010 11/30/2010 Approved
As you can see, in the first row of data, a "1" has been moved from the Start Date column to the Associate Name column. Because this is a databind I don't see how this is even possible. I'm just curious if this is a known issue or just some random fluke. Here is the relevant code:
check the VB behind code for any syntax errors.Unable to add new rows of data to a database using the DataGrid control.Compilation Error message is located at http://cforedu.com:View snap shot images of each line error at http://cforedu.com/snap.pdfThe VB code behind reads (revision 1.3):
I have a web application that takes information entered by the user and displays it in a few datagrids, that are located withing a multiview.
In order to enter a row to a datagrid the user enters some information and clicking on a button calls a function that adds the data to an arraylist, which is the source of the datagrid. In addition, every postback the data is binded to the datagrid.
It all works fine in the first time, but from the second row and on it enters only parts of the data and ignores the rest.
I have a DataGrid bound to an ObjectDataSource, as you know once the DataSourceID on DataGrid is set, data binding happen automatically without any coding. But due to requests from end users, I need to prevent the data binding when the page is loaded the first time, i.e. data binding should only happen during PostBack. How do I do that?
