DataGridViewCheckBoxColumn Won't Show

Apr 21, 2012

I'm trying to define a column in my DGV that has a DataGridViewCheckBoxColumn. I've set the "FalseValue" to 0 and the "TrueValue" to 1. When I run my app, the column just shows 1's and 0's which were retrieved from the Database. NO CHECKBOX appears!

DataGridViewCheckBoxColumn Not Showing Up?

Jun 2, 2011

It's been a while since I've had to add a CheckBoxCol to a DataGridView, so I copied and pasted the code directly from the example shown in the MSDN library page here: [url]Anyway -- the column is added as expected however, there is no checkbox! (see the column "Accept" in the image I've posted). I was hoping I am missing something easy/obvious, and I've had success with this before in other apps so this is becoming frustrating.DGV's Datasource is set to a datatable found in a Dataset. Everything loads just fine. No errors.

DataGridView DataGridViewCheckBoxColumn Copy Columns?

Feb 7, 2012

I have a datagridview that is bound to an access database. The first column is a checkbox, the second is first name, the third is last name, the fourth is start time, and the fifth is end time. Is there a simple way that can either be explained to me, or demonstrated with some example code to have the data copied from the first name, last name, start time, end time when the checkbox is checked in the corresponding row? (there are other columns in the datagridview, but i only want the first four cells copied that are in the same row as the checkbox to be transferred to the second datagridview. This would also have to be able to work for each checkbox in each row)

DataGridViewCheckBoxColumn, Allow Only One Check In Entire Column?

Oct 13, 2009

I have a DataGridViewCheckBoxColumn and I am trying not to allow more than one checked boxes in the column. So after one is checked, when user tries to check another one, i want to prevent that and not have more than one checked box in entire column. I used whole bunch of events but nothing is helping me... Some time it seems working but if i double click the checkbox, it puts the checkbox... sometime it puts the check mark on my third click (not on first, not on second but on third...) What i want is only one checked box and if use tries to click another one don't let it happen.

CheckBox In DataGridViewCheckBoxColumn Won't Change To False When Clicked

Jan 9, 2012

For some reason, I can't change the checkbox from True to False when I click the checkbox in my DataGridViewCheckBoxColumn called "Select". I setup my DataGridView (dgvWBFOrphans) with 5 TextBox columns that are Read-Only and 1 CheckBox column that is not Read-Only. I use a stored procedure and data reader to load the DataTable which is used as the DataSource for dgvWBFOrphans. I want all the checkboxes to default to True and allow the users to uncheck certain rows in the "Select" column.

Dim dtOrphans As New DataTable
Using cnn As New SqlClient.SqlConnection(clsDBConn.clsDBConnections.prpConnString)
cnn.Open()

Fill Combobox Using SQL Show Tables - Datagridview Does Show Table Names In Db Using The SHOW TABLES Sql Statment

Jun 6, 2011

SQL statements:

SQL = "SHOW TABLES;"
Try

conn.Open()

The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

Show An Explanation And For The Addition And Subtraction - Show It On A Number Line

Mar 7, 2010

I'm writing a program for my algebra students to practice integers.Stuff like....

3-6
-4 + (-5)
3(-4)
-15 � 3
etc.

I want to show an explanation and for the addition and subtraction, I want to show it on a number line. For example, if the problem is 3 - 7, the number line should show and arrow to that goes right to 3, and then left 7 units (starting from 3). Then the student can see that the answer is -4.I could probably do this with some string manipulation, but what would be the easiest way to do it in a picture format? Maybe a bitmap.

FrmForm1.Show V. FrmForm1.Show Dialog?

Apr 4, 2009

As a continuation of my previous posting, which we were able to resolve, I am running into the same problem again, due to being unable to use frmForm1.Show().In my last situation I had to use frmForm1.ShowDialog(), which worked in that case, as it called another form, for example frmForm2.However, now I have a program that is sometimes required to recal frmForm1, and I get the following message: �Close the form before calling ShowDialog.But, in frmForm1,I include, Me.Hide() and Me.Close(). Also, before recalling frmForm1, from a procedure under Main(), I have added the following

frmForm1.Close()

To me that would suggest the form is closed, dead and buried, but the programme still stops at the point of:

frmForm1.ShowDialog()

With the same message: �Close the form before calling ShowDialog.

Getting $ To Show Up?

Mar 11, 2012

I was able to get my code to work, but I forgot that I needed the $ in the results. I tried adding a string which did get a $ to show up, the only problem was that when I plug it in I get $1.00 to show up for each or for it to go up in increments. It works perfect with the string, but I have to have the $. This is my code:

Public Class Form1
Dim gallons As Double ' total gallons
Dim total As Decimal ' total price gallons times grade price

C# - Two Controls Show Before The Others

May 14, 2012

I have on a form a UserControl that I use as a Data-Entry form. I show and hide it constantly with new data. Often (not all the times) the same two memo-boxes are shown on the screen first for a second, and then the full control is visible. I found this link, I'm not sure if that's my solution, but in any case I don't know where to call it and when. EDIT: I noticed that it happens 'only' if the program is idle for a couple of minutes. I could show and hide the control 10 times one after the other no problem. but if I hide it and show it again after 2-3 minutes then I get this behavior.

I guess it has to do with the time it takes to reconnect to the MsSQL database to pull the data. But how can I tell this 2 boxes to stay invisible like there parent until the parent is ready to show?
