DB/Reporting :: Unable To Check A Checkbox In A Datagridview
May 17, 2011
[code]I want users to be able to click on the checkbox in field4 and add all of the data plus the word Holiday to my database when they click on the box in that field, but right now it's not allowing me to click on the checkbox, can someone please assist? Also, I did have this working for that field but it would only allow me to add the first line of data, what in my code would not allow for the additional lines to not add their data as well?
I want to make my checkboxes to work as a filter for my DataGridView. The checkbox.text is the thing I wanted to use for filtering.My problem is that, when I click on the button with one or more checkboxes checked, my datagridview shows no data. (Of course, before I pushed the button it did).
I have a form with a datagridview.This datagrid is getting populated from Database.Im able to fill the data in datagrid.I have added a column of checkbox type in the datagrid other than those columns which is getting populated from Database.I have added filters on the form,once the record is populated,my requirement is should be able to check and uncheck the record of corresponding checkbox column that i have added.For Example:In my datagridview RollNo,Name,Address,MobileNo are some fields that are populated from database.I have already added these columns in my Grid by click the smarttag available on Datagrid and then selecting Edit Columns option.Above mentioned fields are all textbox columns.Apart from these columns i have added one more column of type checkbox before my mobile number column.My requirement is after data is populated i should be able to check and uncheck my checkbox column in front of those mobile numbers to whom i want to send a message.
I have a datagridview that is bound to a binding source.I used the following code to add a checkbox column to the datagridview:
Imports System.Windows.Forms ... Dim newcolumn as DataGridViewCheckBoxColumn Datagridview1.Columns.Add(newcolumn)
The checkbox column shows up successfully, but when I try to click any of the checkboxes,nothing happens.The cell remains unchecked.It blinks, so I know that it is acknowledging the click, but the checkbox state does not change.
I have an Access database that is updated directly in Access. I'm trying to write a program to 'monitor' the database, and have a DataGridView control showing the contents. When the program is first started, it shows the current data in the DB fine, however, I've been unable to get it to refresh with any updated data from the mdb file. I have a timer running on 5 second intervals, and if i clear the dataset, the DataGridView refreshes to empty.
I have a form with 2 datagridviews on it, each connected to to table in a database: datagridview1 and datagridview2.Datagridview1 has a column called names and a column called recievers.Datagridview2 has a column called senders and a checkbox column in it.
The user will first select a row in datagridview1 and then click a check box in datagridview2.What i want to do is when the user clicks a check box in datagridview2, i want it to copy the value in the "names" column of the same row, to the receivers column of the selected row in datagridview1.

I have some DataGridView code written in vb.net. (Nothing is attached to a datasource.)The 4th column is a checkbox cell.How do I detect if that checkBox is checked or unchecked?This code strangely reports TRUE or FALSE at random times. It even turns ON the checkbox in rows other than the row I clicked in. (Huh?)
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick Dim whichGrid As DataGridView = CType(sender, DataGridView)

I've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.
1) I have a checkbox field in a datagrid, and when you check the box, it highlights the entire current row, and when you check the next one, it stops highlighting the first one and highlights the one I just clicked on. What I would like to know is how can I keep all the rows with a checkbox highlighted? 2) I have a column in my datagrid that I have changed to combobox and I did two things both gives me this error, first I inserted the values for the combobox in the collection. Second, I connected to one of the tables with a binding source and has one of the columns as the options (advisors).
Each student has a different advisor so the field gets set to the correct advisor each time but the problem I am getting is when I scroll (doesn't happen for a little while) I get an error so i put in this sub to handle it and the error message box says: Error Happened Formatting, Display.

I have been using Access 200 as my database of choice with Visual Basic 2008 Express.I am trying to start usingSQL Server Express but having a difficult time with it. All of the instrctions I have tri9ed seem to be written for someone who already knows the answers. Here's my problem.I wrote a program using Access, with one table and five queries and it works fine. Using that program as a baseI created an SQL Server database within Visual basic. Naturally I changed my code to reflect SQL rather then OLEDB.When I try to run the program I get an error message telling me that the database is not registered. When I use the SQL Server Management Studio Expres, it shows my database by give a big message that the database is not registered.
I'm writting a vb application that will go out and pull data from an internal webpage which I have no control over. I need to check a checkbox on the webpage. The checkbox ID is "Checkbox".The checkbox has javascript code in behind it that executes an onclick command: onclick="getMore(); return false; I've written code to perform the check of the checkbox but I guess the onclick is not happening. Here is my code so far. The user is given a form, they type in a # (SR.Text) and hit GO:
Code: Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If SR.Text <> Nothing Then
[code]....
As I stated ealier the javascript "onclick" is not executing.
I have a datagridview with a checkbox column.i want to check whether checkbox is checked or not.If the checkbox is selected it should output as "True" in messagebox and if checkbox is not selected it should giving me a message "False".
I am reading values from a database (boolean) and if true, I want it to check a checkbox,and if false, keep the checkbox unchecked. The lines look like this: blEnergy.Items.FindByValue(1).Selected = track_usageIn this case, track_usage is a boolean value.This way does not actually create the check mark in the checkbox like I wanted it to. What is the best way to do this?
I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...
My Code , Dim dtParm As DataTable = MyDataSet.tblParameter Dim dgv As DataGridView = Me.dgvResultNum_DataGrid

We are trying to modify a program to control a usb relay device. Essentially what the program originally does is give you a series of check boxes that you check to make the relay fire. We tried to modify the code so that the box is checked after 5 seconds using a counter and an if statement. It works, but only partially, what happens is the check box shows a check, but the even that is normally triggered does not happen.
I have about four columns inside my listview.I also have checkboxs that are located to the left of the listview. A checkbox is added to first column but how would I check if the checkbox is checked?
