from textbox and it is unbound from database.I have successfully added some codes and it
works but am having problem when adding new data...Where, when i click on the "Clear"
button to input new data, all the data which was already displayed in the DGV is replaced
by the new data in the first row...all i want is to be able to add data in a new row and
keep the first input...I wanna the app. to display data input in the DGV and then be able
to add new data in a new rowThis is important for me to be able to go to the next step of
the app development.[code...]

In my form I have four text boxes (2 in each row); Textbox_FN1, Textbox_LN1 in row 1 and Textbox_FN2,Textbox_LN2 in row 2. When a button is clicked; I want to pass the row number to the following procedure which needs to read values from two text boxes and write to DatagridView. The code below writes the literal "Textbox_FN1.txt" but I need actual value from the textbox control.

Parameter name: index.at this line of code GridView3.Columns(1).Visible = False yet the grid has rows and more than 2 columns. Note that the Gridview columns have NOT been defined at design time.

I have an unbound Gridview that is populated by a Linq to Entities query and would like to convert string values in a particular column to lowercase. In the Gridview's RowDataBound event, I have tried StrConv(e.Row.Cells(3).Text, VbStrConv.ProperCase) but this doesn't work. I have also tried StrConv(emp.Name, VbStrConv.ProperCase) in the LiNQ to Entities query but still the Name values returned are to converted to Lower-case.
Protected Sub GridView3_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView3.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
For i As Integer = 0 To e.Row.Cells.Count - 1
Dim cellDate As Date

tried quite a bit of iterations, not a local admin so i dont want to even bother using the data connection wizard, want to do all of this with unbound controls only the harder way for learning purposes and also so i dont have to keep logging in as local admin and create data sources in the future. Cant really seem to get the table to fill, it appears always with blank fields, and tried many different ways. Currently using vb. net 2005 msvs.[code]

I have seen multiple examples on google and on these forums about how to do this. It seems there are two approaches:
1 - Add the column directly to the DGV and populate it
2 - Add the column to the underlying dataset

I have a form and in that form is a datagridview listing information from a table in a database. The datagrid is setup as read only and the user is unable to move the columns around. The purpose of the datagrid is to allow the user to select entire records and press a menu button that does some action on them. To make it easier to use the very first column in an unbound data column that I fill with a number representing the row count so 1,2,3,4.... this makes it easier for the user to count how many rows he has selected.
The problem is that the unbound column moves to the last column in the datagrid at random times.This only happens in development not after the application has been deployed. Its annoying because lets say I go in to add a label or change a menu item on the form that has nothing to do with the datagrid I have to make sure that the unbound column hasn't moved.Has anyone else had this problem mixing bound and unbound columns in a datagridview.

I am designing a form to Enter new City Name list where i accept following fields
CityName, District, State, Country, Pin.
because a State names and Country names can be retrived from earlier entries, i want to allow user to select desired name from a list in combo box or a list in Auto Complete Custom Source for text box, to do this i have added a Table Adapter to underlying DataSet having Query "SELECT DISTICT STATE FROM CITY ORDER BY STATE".
Now, how do i use this Table Adapter to fill the ComboBox List without binding
And also Custom Source List for TextBox.

I have a gridview which generate a link based on certain condition inside the Grid from code behind. What I want to achieve is when I click on that link, I want to catch all the information from the row that the link is in. So for example, if row 1, 2, and 4 has links in cell 5, When I click row 1's link, I want to get all the cell value from row 1. When I click on row 2's link, I want to get all the cell value from row 2, etc. I am somewhat close but not quite. When I click on row 2, I still get the same value from row 1, same as when I click on row 4, I get the same value from row In short, I want to get the row's value based on the link that's in the row. Here's my code:
$('a.SendEmail').click(function(e){
var Name = $('#<%=GridView2.ClientID%> td:eq(1)').text();
var Id = $('#<%=GridView2.ClientID%> td:eq(2)').text();
[code].....

I am using visual studio 2008. I have a winforms app that takes data from an xml doc. I store the data in a ms sql database that I have created via a stored procedure. When Irun the app the data from the xml doc is captured and put in the database, but I can only see old data, the data that is captured during the current session can not be seen unless I close the app down and restart it. I have tried the following, and every variation I can think of to allow me to see the new data but to no avail.[code]
