So I have a text box in a form. The test box needs to take the value entered and insert it into a column within a row in MySQL.

Get All Data From A Column In A DataGridView

Jul 22, 2011

I have a data grid view that contains several columns. The first column is the only column I care about and it contains Result IDs. The view may be filter from time to time. I want to get the Result IDs from all the visible rows and put them into a table variable so I can use ADO.Net to send that table to a SQL Server stored procedure. I currently use a loop (see below). Is there a way to do this quicker without a loop? I'm new to VB.Net and I was hoping .Net would have an impressive method to do the same thing the loop below is doing.

Private Function prvfnc_GetResultIDs(ByVal dgv As DataGridView, ByRef dt As DataTable) As String
Dim rw As DataRow

Get Column Data Type In Datagridview For Comparison?

Dec 15, 2009

I am writing validation for a datagridview which may open a number of different tables (dependant on what the user selects). The idea is that the user will select a lookup table to edit or add too, the datagridview opens (via a binding source) and populates itself with a specific table's data.

The user can then edit the data in the rows and when they are happy update the dataset which in turn updates the database table.

This all works except there is no validation per say prior to the update. As the datagrid loads a different table dynamically I cannot predetermine table column names (without writing a mass of hard coded values) so I would rather go by the datatype of the column since the tables all follow a similar format.[code]...

Bind Data From Database To A Specific DatagridView Column Name ?

Feb 24, 2012

I would like to bind different queries for a long set of columns in datagridview that has been set already during the formload, e.g:

With dgvGrid

.Columns(0).Name = "Dept Code"
.Columns(1).Name = "Emp ID"[code]....

there are still more of it. The data needed for those columns is coming from a different table.

DataGridView Multiple Row Selection, Specific Column Data Get?

Apr 23, 2012

So I have a datagridview being populated with data from a database.At this point a user may or may not selected (via mouse click / key press) one or more rows within the datagridview.I need to (upon selection) create a new dataset, datatable and add rows with the some data from the said datagridview.

For example, if a table had nothing but names, e.g.

Joe
Sean
Larry
Chris

Upon the user clicking, dragging a selection over Sean and Larry to add those names to a new dataset so I can pass it to another method for further processing.

[Code]...

Input array is longer than the number of columns in this table.It looks like I'm either missing a column declaration or adding the table to the set?

Display Data From Checked Box Column Row In The Datagridview Control

Mar 14, 2011

I am having trouble in allowing the user to select the row in the datagridview.

I managed to include the checkbox column in the datagridview but i do not know how to wrte the code such that when the user wants to update or edit the data in the checked row, he just have to check the affected rows checkbox, can be one or many, and then click on ok button, which will then lead him to the data updater form, allowing him to update the data.

Currently i have the below code which can populate the checkboxclumn only.

dbProvider = "PROVIDER=MICROSOFT.Jet.OLEDB.4.0;"
dbSource = "Data Source = '" & Form1.TextBox8.Text & "'"
con.ConnectionString = dbProvider & dbSource

Unbound Data Column In A Datagridview Moves Position?

Mar 10, 2010

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.

VS 2008 - Entering Data Into DataGridView ComboBox Column

May 7, 2010

I have this test form where I'm testing the idea, but ran into a snag. Now the main idea is to load all the data from a dataset into the one column of the datagridview. This works perfectly as shown in the image. Now there is something that I want to happen, but just can't get it right. when on the DataGridViewComboBox Column I also want to be able to type in my own data if the one I want is not available in the combobox.

Also if there are 50 values in my combobox and 2 of them are:
jacky, jacson
When I type jac, I want the combobox to only give me the options starting with "jac"

Here is the code that I'm currently using:
Dim dt As DataTable
Dim dsNewDataset As New DataSet()
Dim i = 0, intSetArray As Integer = 0
Public Function JT_PullDataWithCOLUMNS1(ByVal Cols As String, ByVal TableName As String) As DataTable
