I have bind the DataGridview with DB. To add the data from textboxes to DataGrid, I use the foll. code-
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Try
Dim row0 As String() = {TextBox1.Text, TextBox2.Text, TextBox3.Text}
[CODE]...
Error is coming: Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound. there is no any way to add data to the Gridview if we bound it to the Database.
Algorithm to count the time that occured on the same period, how to bind the dictionary to the GridView? Pls take a look to the answer.
I tried to add a GridView and then on the code-behind: GV.DataSource = timeRangeCounts and bind it, but in return:
The data source for GridView with id 'GV' did not have any properties or attributes from which to generate columns. Ensure that your data source has content.
take a look at the code below:
The first helper class is used to hold the counts of exact and sub range matches:
Public Class TimeRangeCounter Property ExactRangeMatch as Integer Property SubRangeMatch as Integer
How can I bind the GridView so that one row is equivalent to one item in my MyListOfObjects list, and so that the data will populate and persist across page loads or postbacks? I've never done custom databinding like this before, so a full explanation would be very helpful. All the tutorials I've come across so far only talk about using GridViews directly with Database query results, and that's not what I need.
I have a Master Page with nested pages in ASP.NET. Fairly simply I want to databind some hyperlinks to a gridview for the master page. This however is throwing a null reference exception when I try to set the DataSource.
I tested the code on a separate page and it works as expected. When debugging I can see the Page_Load Sub hit twice, I don't know if this is the cause I have one nested page being loaded, this is a blank page at the moment
EXCEPTION Object reference not set to an instance of an object. MASTERPAGE CODE BEHIND Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
I have an array of objects I get from a web service. The 1st element in that array is meant to be displayed in a asp.net literal control. The rest of the elements are meant to be bound to a gridview.
I have a variable defined as follows:Dim iRows As List(Of String())I've also been converting that to a list of lists just to make it easier to work with.Dim iRows As List(Of IList(Of String))I would like to bind that list to a GridView using the contents of the nested array/list to dynamically define the columns. I don't know ahead of time how many columns there will be, but I do know that they are all the same throughout the list.
I have radio button list in a gridview that needs to be bound to a column. If the value in a column is 0, the first radio button is selected, if 1, the other is selected. This is the code, some of it is partially removed because it is not necessary
So in this gridview, there is a column for status and I want to have a drop down list with Pass, Pending, Fail appear when the edit button is clicked. These values are already in a table, so I need to somehow bind from this table to each ddl for every row.Here is the column from the gridview. As you can see, I would like to just have a label showing when not in edit mode, and a ddl when the edit button is pressed
<asp:TemplateField HeaderText="During Production Status" SortExpression="DuringProductionStatus"> <EditItemTemplate>
I was assigned a task so as to bind the user related data into a grid view on user login. I have got two web pages, one of which contains Login and authentication information. This goes fine. When user was redirected to second page, I need to provide a GridView control where user details should be automatically updated in grid view control in the back ground.I have three different fields which were saved in sql table. particular user details need to be retrieved from the sql table on user login and bind the data to grid view automatically.
I'm currently developing an application with a reasonably complex DataGridView that allows the user to build the lines of a sales document: Quantitiy, Description, Price, etc with some additional fields to help calculate price based on cost or discount i'm sure you get the jist - all this means we're not just diplaying data but adding and manipulating it - It also means there's mainly decimal fields, nit just simple text fields
Now, i'm new to VB.net, so i've perhaps done things a bit backwards during my learning curve, namely designing and coding my DGV before creating the underlying database table and binding to it - so as i'm sure you can image there's a bit recoding to do to allow for the fact that it's now bound to a datasource.
I'd got the DGV working just how a wanted it to, but now that i've bound it to a datasource i'm hiting multiple problems with: Formating the appearance of figures in the DGV Problems with blank fields while enering data (before the i try to save the data back to the database) How the DGV is functioning - it seems to behave differently when adding lines to a new sales document than it does when adding lines to an existing sales document
And given that when saving edits to an existing line i need to provide a valid update command i'm begining to think that it might be easier to scrap the databinding altogether and just Select, Add and Edit the database with code rather than binding the DGV in the IDE
I've read various threads about avoiding databinding due to it's limitations, but i've also read that it's far better in later versions of Visual Studio and .net. and i'm using VS2010
I'd just like some advise as to whether my gut feeling is right or whether i should persevere with databinding the DGV. i've noticed some quirks of databinding while working with other controls such as text and combo boxes, but i've overcome these and the result seems to be easier than coding the data transfer manually.
But i'm really struggling with databinding the DGV and the fact that i'm dtatbinding to a seperate table to the rest of the controls is leaning me away from databinding
How can we databind a datagridview to some of the My.Settings (user scoped) properties so the user can edit the values? This must be to a datagridview. I know we can bind to My.Settings in a form with textboxes and so on, but in this case we just want it as list of editable strings in a datagridview.
Of course some My.Settings entries can have different datatypes which complicates matters but generally we're only working with strings and booleans. Also, let's assume the user understands that he must enter the string "true" to set a boolean to true. No checkbox column needed. Here's what we are using (and it works), just looking for a better, leaner way: [Code]
I have a datagridview who's datasource is a BindingSource. The problem that I need to resolve is that the DGV has 6 columns, 5 of which come from the same database table, while the other column comes from another database table. Is there anyway of configuring the BindingSource that will make it contain all 6 columns?
The same grid in Part 1 works in the way that when a user selects a row, textboxes and comboboxes are populated with the DGV Row of data in order for the data to be modified. When the user makes any changes, this modified data needs to update the DGV row or BindingSource. How do I associate the changed values back to the BindingSource or the DGV?
I wrote small program which is reading xml data to datagridview (table). I used open file dialog and everything works fine. Now I would like to add some edit options to my program (add, delete, save). I decided to bind data and then use binding navigator?
I'm planning to create a program that would bind the search results into the datagridview in vb.net. For example, listing of students that has the same course in the datagridview.
I have combobox in a form. The combobox is bound to a table and displays the list of values as expected. What I want to do is also bind the combox to another field in a different table similar to the way the datagridview with combobox works. That is the dgv is bound to the combobox column but the dgv's bound value sets/reflects the value selected by the combobox. I can't figure out if this is possible with a standalone combobox.
know it is possible to have bounded and unbounded columns in a datagridview.Is it also possible to have bounded and unbounded rows?I knows its unorthodox, but I want to have two rows in my datagrid per item in my object list One row is bounded to the properties of each item; below that I want an unboundedrow of checkboxes for each property But since when binding the datagridview sets the rowcount equal to the list count, I'm not sure its possible.
I have a DataSet with many tables and a single DataGridView. I need to select a value from a combobox and then pressing aButton to show the selected table to the DataGridView. For example if I select from combobox "Selection1" I would like to show to the Datagridview the contents of the table called Selection1. I paste the event that I thought might work but doesnt show a think: Private Sub aButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles aButton.Click
I'd like to partition my search results (which is in a DataTable) into groups of say 100 so the user navigates through them a chunk at a time.I thought I could bind an array of DataRows to a DataGridView as the DataSource but it just does not work. This is the code I tried
DataGridView.DataSource = (From r In DataTable.Rows Skip 200 Take 100).ToArray()
I'd like to stay away using the DataGridView's VirtualMode.
My DataGridview already binded to Datatable dt1 DataGridview1.datasource = dt1 and i want to add another Datatable dt2 into datagridview after 20-30 minute and want to keep dt1 as well as in the datagridview ..How i can do that..
I have a DataGridView where we select a line and a new form appears so I can change the data.g:
edit.txtQtd1.Text = DGV.CurrentRow.Cells(6).Value.ToString edit.txtProd1.Text = DGV.CurrentRow.Cells(7).Value.ToString The data is loaded from that line to textbox's. everything goes fine, but when I edit the
