Having A Grid Hold Its View State?
May 29, 2009
I have an Obout grid that I have been trying to work with and I put all of their code in my site so that I could have my grid stay expanded when the page does an automatic refresh.How or what is the correct way to code for a If (Page.IsPostBack) code.Next is there an online free convertor, translator, for javascript to VB.NET; if not is there someplace that I can go to where they will explain the different meaning of the javascript in comparision to what it would mean in VB.Net (such as var I think means dim or it could mean something else I am not sure.)Final is there a good source on grids and how they work with a view state or a session? But it needs to be basic as I am still trying to understand all three of those processes.

I have students who will be enrolled into a course. The student grid view has many columns like client_no, student_name, date_of_birth, address, etc. There are over 100000 students so I will need to filter the student grid view to find the correct student to enroll in the course. Once they are found, the user selects them and somehow moves them to the enrolled grid view. If a student drops out then they would be removed from the enrolled grid view.This process needs to be easy to understand and use. Are there any examples available or other suggestions on how to do this?

This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?

i have datagridview populated with stock code, name and description.And i have docked my datagridview to the bottom. so whenever the form is resized, the bottom section will be occupied completely with the datagridview.But i want to display one extra empty column and multiple empty rows to completely fill in the datagridview.The extra empty column width will be adjusted to the right end side of datagridview.And the no of empty rows will be generated based on how many is required to fill up to the bottomSo that i can create datagridview with full column and row even though some columns or rows are empty.

Ive decided to move from VB6 programming and Im not really sure where to go..Ive got a copy of VB .Net 2003, and Ive also downloaded VB 2005 Express edition, with a possible view to getting hold of Visual Studio 2005 to program VB 2005. The problem (and confusion) that I have is - what is the difference, and which should I turn to?Am I right in assuming that VB.NET 2003 and VB 2005 are different, or am I ok to learn .NET 2003 until the 2005 version comes out?I know this might seem like a dumb question, but I want to move onwards and upwards and am a little confused, as I dont want to concentrate on 2003 if I'm going to be learning an outdated language in the next couple of years.

I have a label's value that is posted back from a previous page and I want to use this label to do a simple calculation in the current page, but when I do the calculation the page (refreshed) the value of this label and automatically deleted the value (Since there would be no value in postback when it refreshed).
Here is the code behind file:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Label2.Text = Request.Form("Hidden1")
End Sub
and here where I want to use the label
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Stotal As String
Stotal = Val(Label2.Text) * 10
Label3.Text = Stotal
End Sub
How can I save the value in the page via view state or any other method?

I have a grid view with a nested text box in it. I would like to turn view state off but the fact of the matter is when data is posted, the text boxes inside the gridview aren't available (there are no rows in the gridview on postback)I am using ASP.NET 2.0 so would this fall into control state, not view state?
Sample ASPX code of the gridview:
[Code]...
Control's information is not stored in the View State (for things like selected value and .text etc.)Control state, introduced in ASP.NET version 2.0, is similar to view state but functionally independent of view state. A page developer can disable view state for the page or for an individual control for performance. However, control state cannot be disabled. Control state is designed for storing a control's essential data (such as a pager control's page number) that must be available on postback to enable the control to function even when view state has been disabled.[URL]..

I have a grid view which uses SQL to calculate information that I need! I want to put this calculated total into another table in database.
SELECT StaffDetails.StaffID, SUM(HolidayRequests.RequestTotalDays) AS Expr1 FROM HolidayRequests INNER JOIN StaffDetails ON HolidayRequests.Username = StaffDetails.UserName WHERE (StaffDetails.StaffID = @staffID) GROUP BY StaffDetails.StaffID, HolidayRequests.ApprovalStatus HAVING (HolidayRequests.ApprovalStatus = N'approved')
It basically calculates the total number of approved holiday requests for a staff member which is correct. I want this number to then update the HolidayTaken field in another table each time a holiday is approved.

I wanna ask something regarding the updating of database.
basically i am doing in 3 tier.
and i have a database table called 'SchoolTalkAppt'.
in the table itself, i have 1 empty column which i will be filling in using update statement.
the other columns are already created and filled into the table earlier.
i just have to update the 1 empty column (FirstName) and ALSO update the Status from 'pending' to 'Assigned'.
i decided to use drop down for both the name and the status.
the names available in the drop down i would be retrieving it from another table and populate it inside..while the status i manually added 2 options, 'Pending' and 'Assigned'.. not retrieving from database.
Since i am only required to update the FirstName and Status, in the update statement i put in the update for FirstName and Status only.[code]...

I'me getting real dumb with this one....I have this class:
Public Class whatever
Public id as string
Public name as string
public date as string
end class
Wich I use with this code:
dim personlist as new arraylist
dim person as new whatever
person.id="1"[code].....
and then i repeat so that i can fill my arraylist with all the information that I want to show in my gridview.The problem is this:
gridview1.datasource = personlist
gridview1.databind()
When executing, I get an error saying :
The data source for GridView with id 'gdpersonlist' did not have any properties or attributes from which to generate columns. Ensure that your data source has content.

I need to display (read-only, I don't want the user to be able to modify the data) a set number of log entries. I figured using the data grid view would be the best solution. Basically the data is an error log that contains 3 fields (columns)
ID (a number from 1-20), Flag (number from 0-255), and a Description (string). I don't want the data linked to any database or anything.
These events occur asynchronously so I need to be able to add events (rows) to the data grid as they occur.
I also need the ability to clear all events (rows).
I guess the first question is if the data grid view is the best control in VB to use.
Is there a good example on using the data grid on how to add data to the data grid view one row at a time?

I have to turn this program in TOMORROW! I can't seem to figure out how to do this section. If someone I can do the second part.I have two text files, one is a single dimensional array, and one is a two dimensional array. One titled "Months.txt" and the other "Rain.txt".The problem is I have to read those into an array, and then after that, use a query to pull the information and display it into a data grid view style box.The problem I'm facing is when I pull the "Months.txt" text file, which has the months in order from January....December, and try to display it in the data grid it puts the length of the names of the months, not the actual months. me on this matter? I've tried to no avail. Also, how would you add all of the numbers in a single row of a two-dimensional array to give a total to display in the data grid? Also, the column?
