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.


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.


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?

DatagridView Column Selection

Jun 21, 2010

Am using 08 and i have a datagridview with 3 columns. The first column has a button as the columntype with the name "UserName". Now, i want if the user clicks only on the UserName which is the first column, but not the entire row, it should display the value of the UserName column only. If other columns are clicked are apart from the UserName, nothing should display. So there will be a for loop that will itera te through all the rows of the datagridview.

So i have something like this:

Selecting Data In One DataGridView Based On Selection In Another?

Oct 5, 2009

NB: I'm using Visual Basic.NET?My form has 2 DataGridView controls. One of these is bound to a DataSet, the other isn't visible - at least not until the user selects a uniqueidentifier cell in the 1st grid.When the user makes this selection, the 2nd grid will become visible and display the row from another with the same id as the one selected in the 1st grid.So, basically, I want to dynamically display data in one grid based on user selection in another grid.My code looks like this so far...

Private Sub RulesGrid_CellClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles RulesGrid.CellClick

DataGridView Multiple Column Sorting

Jun 9, 2009

I'm trying to sort multple colums in the DataGridView which is unbound. I would prefer to sort by using a DataTable/DataView but for some reason another developer in my team experienced other problems relating to sorting so he abandoned using the DataTable to fill the grid :(

Here is the senario: I want the user to be able to choose which columns they want sort on. The way I envisaged was to show a form with a listbox, a grid and 3 buttons (Add to sort, Remove from sort and Apply Sort).

The list box would be populated from the parent form grid column headings.
The grid will show the columns and sort direction.
Button 1 would add the selected item of the list box to the grid.
Button 2 would remove from the grid the selected row.
Button 3 would Apply the Sort in the order of the grid and the columns SortDirection.

Now I looked at How to: Customize Sorting in the Windows Forms DataGridView Control using the IComparer [URL]

how I can use the IComparer to sort on multiple columns that a user has specified or another way to sort on multiple columns using unbound data.

[2008] Gather Specific Data From Multiple Text Files?

I'm trying to write a program that will take emails that I have saved from outlook as text files and scan it for specific data, and return those strings to a textbox (i will modify it so it outputs the exact way i need it, i just need to grab that info faster than it takes by hand). I dont know how to go about actually grabbing that specific data.

From: Person

Subject: Subject


There can be only one grouping (denoted with asterisks, they are separated in the emails like that as well), or 50 and any number in between. I only need the information as shown in the text file example above (sometimes, it is blank or not there - if that's the case just skip and to alert me that it was skipped).

Get All Data From A Column In A DataGridView

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.

im in the process of using code to return the ip address of my machine its working sorta correctly i can get the right ip address if i change the addresslist.getvalue(0) from [0] to any where up to [5]this im guessing is an array of information in the network adapter or something im not real interested in the other information in the other values my problem is depending on weather i have ipv6 options enabled in my adapter settings the true( is in value(2) for on and value(3) for off also i tried it on another machine and it came back as value(5) of 12 my problem is i can display every value() that has information in it in a text box but i cant make the program find the right address to use( this code runs and produces a multiline textbox with up to 11 lines of data in it and the ip address is visible in the list of data

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]...

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.

dbSource = "Data Source = '" & Form1.TextBox8.Text & "'"

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
