Asp.net - Binding Arraylist To Grid View?

Jun 18, 2009

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.

.net - Selecting A Row(s) With Multiple Columns From A Grid View And Add Them To Another Grid View?

May 6, 2009

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?

Data Grid View Header Grid Color

Jan 14, 2010

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?

Data Binding Options As The MS Grid?

Jul 27, 2010

anybody recommend a 3rd party DataGrid control similar to the MS DataGridView.I would like something that can handle null vales without throwing Object reference errors. Decent hosted controls support (for things like Type-In Combo Boxes, date time picker) Similar Data Binding options as the MS Grid and something that will look like a normal grid and mix well with the standard MS Controls.

.net - Binding A Dictionary To A WinForms Grid (or Combo)?

Aug 24, 2011

You have a pseudo-table class and a pseudo-row class. The row is somewhat generic and has no strongly-typed fields. It follows the typical dictionary interface

Dim age As Object = person("Age") 'accessed via default property Item

vs

Dim age As Integer = person.Age 'an actual property typed as an Integer


What's the pattern to use so that we can bind our pseudo table and its rows to a grid or combo box?

Dim id As Object = rs(0)("Id") '913
Dim name As Object = rs(0)("Name") 'Ted[code].....

VS 2010 App The Uses Data Binding With A Grid Control And Textboxes?

Apr 15, 2011

I'm looking to see if anyone has a sample app or has a link to such an app that uses data binding with a grid control and textboxes and is able to insert, change and delete from a datatable which gets updated to a sql server database.I have done an app that has the grid control and the textboxes already and is able to change and delete from the datatable and that action is reflected in the grid control because it has the datatable as the binding source.

The problem I'm having is when the user tries to insert into the datatable I get a concurrency violation error when using the .Update statement to save the changes to the database. This is happening because I don't know exactly how to get those inserts synchronised correcly.I'm sure I'm also doing the processing wrong but here is what I'm doing.When the user clicks an insert button I insert a new row into the datatable. The user now has the ability to enter text into the textboxes. When the user is finished doing that the user can click the save button which issues a .Update statement. That's where the error is displayed

Hide Or Omit Some Properties In Binding Of A Collection To Grid Control?

Mar 26, 2010

My problem is similar to the one described in this article, but I'm trying to use a different grid (DevExpress.xtraGrid) and therefore the answer (if it even works) does not apply for me: [URL]

Briefly, I'm binding the grid to the collection of custom objects - cMessage - to grid's datasource, but I don't want all the propertieties of the cMessage to be shown in the grid. Is there any way to hide some properties from the binding, while leaving them acessible from outside (ie.leave them as public or friend)?

Getting A Value From A Grid View Into Database?

Mar 13, 2012

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.

Update Grid View Using Ddl In VB?

Jan 30, 2010

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]...
