Datagridview With ComboBoxColumn Fetching Data From Joined Table
Dec 16, 2009
I am using VB 2005 professional and SQL Server 2005 express edition.
For the last two weeks I have been trying to have a datagridview control on a form that will have datasource from a dataset with two tables that are related. I want child the column to be a ComboBoxColumn where userts can select options and update the other data(from the other table).
I have two tables in an sql server 2005 database named computers:-
computers
locations
Table computers looks like thisID is the primary key column)
ID Location
Computer139
Computer240
[Code].....
With the location column being a ComboBoxColumn so that when a user enters a new ID say Computer5,they have a choice of a dropdownmenu for the Location column. In the database table computers the item should be saved as well as the index value(to correspond to the LocationID).

easy way to simply load the data from database into a datagridview with one of the columns being a comboboxcolumn. Apparently there is no selectedvalue, selectedindex or value as in a combobox to return the combobox value. What I need is to verify if the database value is 'true' and if it is then I need to set the comboboxcolumn with a specific value.
Ex:
if ds.tables(0).rows(0)("flag") = "true" then
datagridcolumn.selectedvalue = 1
else
datagridcolumn.selectedvalue = 0
end if

I fetch data from an SQL Express database table named ALARMLOG to a datagridview1. One of the columns of ALARMLOG is "TheTime" which has datetime data type values. This values are in the following format "22/04/2010 13:23:45 PM".When I fetch the data to the datagridview1 I get "22/04/2010 13:23 PM".The problem is that I can't display the seconds in datagridview1. I tried the CORVERT command of SQL in order to convert from datatime to varchar but nothing...

I am building a VB 2008 Express Edition application.I have built a database (with a single table) using SQL Server Compact 3.5 and have connected it to the project. I am able to view and edit the data using a DataGridView on a second form (tutorial made this very easy). I need to work with the data in the table within the application. how to easily load the entire table into an array or even read the table a row or cell at a time so that I can make all of the data available for manipulation within the application (the tutorials only seem to show how to display the data).

I am populating a DataGridView from a DataTable with a DataAdapter (VB 2008 Express, SQL 2008 Express). The dgv is for editing (with SqlCommandBuilder) a SQL table. I have added a ComboBoxColumn ("Type"), with a list, and removed the column from dgv ("Reason") who's index it replaces. What I can't figure out is the binding(?) to have the selected text displayed the same value as that from SQL table that is being edited. The ComboBox displays an index of -1, I need the selected text to be the data from row and field which is to be edited. The list is constant. Code so far is below:
Public Sub LoadDgvComps()
Dim myDA As SqlDataAdapter
Dim dsComps As DataSet[code]......

I have a databound combo box column. When a value in another field starts with an 8, I want to make the combo box read-only and turn the background gray so the user knows it is read-only.
Here is the code I'm using, where am I going wrong? It doesn't change the backcolor to gray.
Private Sub dgvTest_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles dgvTest.CellFormatting

i am using a Datagridview on my form. It get's it's datasource from a dataset: grd.datasource=set_temp After that I add ComboboxColumns manually. At the end I loop columns and set values into that cells from the comboboxcolumns. Works perfect so far. Now I click on a header and the sorting is changed, and then the cells from the comboboxcolumns all lose their values, they are all empty.
Why and what do I do to avoid that? Or must i refill those manual Values after sorting?

I have a child form in an MDI application with a datagridview comboboxcolumn. I'm filling it with string values. When I load the form independently of the parent, I am able to set values for the comboboxcells. But when the form is loaded as part of the MDi application, with the same exact code, the cells are empty.

I have a GUI which allows the user to select a report to view/edit. When the user selects a report, it shows the Items in the report. The Item has many properties - most of which are binding properly. One of the properties is Owner, and this is bound to a ComboBoxColumn.
Report
Items
Owner
I have done something very similar to this a few times and had no problems when I set the DataPropertyName, DataSource, ValueMember, and DisplayMember. The only difference is that this time instead of the Item type having an OwnderID it actually has an instance of the Owner object.giving the items bound in the list a self-referencing property that allows them to return themselves for the purposes of setting the ValueMember.However, When I bind it this way:
OwnerColumn.DataPropertyName = "Owner"
OwnerColumn.DataSource = ownersBindingSource1
OwnerColumn.ValueMember = "Self"
OwnerColumn.DisplayMember = "OwnerName"
I get a lot of errors like: Unable to cast object of type 'System.String' to type 'Owner'.
and:
The following exception occurred in the DataGridView:
System.ArgumentException: DataGridViewComboBoxCell value is not valid.To replace this default dialog please handle the DataError event.I was able to get around some of these errors by binding it like this:
OwnerColumn.DataPropertyName = "Owner"
OwnerColumn.DataSource = ownersBindingSource1
and also by making the ToString function on the Owner display the OwnerName property. This seems pretty hacky though - and I think I'm misunderstanding something fundamental as it still does not function properly.

With the two lists (t1s and t2s), I want to display t1s in a DataGridView, and in one column show the T2 property as a comboBox column, which dropdown will show the t2s list such that a new list instance can be selected. T2 has a Name property that should be used for displaying it in the comboBoxColumn.
I'm able to display the dropdown, but remaining a few problems:
1. How to display the correct comboBox "selection" on "load"?
2. How to change the T2 child object instance when combobox selection is made?
3. This is a really basic problem, which suddenly happened and I just couldn't understand what I have changed; The code marked BLUE now just shows empty cells.. While the AutoGenerated columns do show values.. Shouldn't those "manual" columns work?

I have a comboboxcolumn in a DataGridView. I have loaded int with string data that appears in the dropdown box. I have added an event to it for an SelectedIndexChanged. What I am trying to do is autosize the width of the cell in the column based on the string chosen in the drop-down box within this SelectedIndexChanged event. This seems to work but it does not work off the initial selection change. When I select the desired string in the dropdown box the width of the cell does not autosize. I am not sure why.
I was trying to get around this by wrapping an IF stmt around the autosize logic by saying if cell value = "" then cell.width = Max Width of all loaded strings/ However, I can't figure out how to access the string array loaded into the dropdown list

I'm pretty new to VB.Net programming, but have already been able to figure out many things using this forum, but also via the many other forums on the internet.I'm currently stuck with a question though regarding getting the clicked value in a datagridview comboboxcolumn.When I use _Selected IndexChanged and then check the current cells value, what I get is the value before I clicked the new one in the comboboxcolumn.When I use _CellEditFinished, I can get the new value, but only after I selected another cell, or changed focus to another object.How do I get the new value from a DataGridViews ComboBoxColumn the moment I clicked it in the pulldown menu from the ComboBoxColumn?

I need some clarification. I'm planning to make a Scheduler program where it will fetch data from a MS Access Database, and I also want it to upload the data to a web server (MySQL Database) in JSON Format.
In the first process which is the fetching, I'll use System.Data.Ole.db namespace. This namespace mostly worked in MS Access. In the 2nd process which is the uploading, I am planning to use FTP protocol and should be JSON Format.
I was just confused with the second step, is FTP protocol applicable for this process?
I will make an Android apps to view all the data that will be saved on the web server.
