i have added 5 datagridviewcheckboxcolumns to my datagridview programmatically. say i have 20 rows, that equals 100 checkboxes. how can I set each one to checked when I click a button.also i have a comboboxcolumn and only if an item is selected in the combobox for a row, then the rows checkboxes must get ticked.
View 7 RepliesFor 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()

I know my question reads a bit like that 'how much wood can a woodchuck chuck' line, excuse that... I have a repeater with checkboxes. There are numerous rows in this repeater - I never know how many - I want only one checkbox checked at any time. If the user changes the checked checkbox, any pre-existing checks are unchecked therefore maintaining a single checked checkbox.
I am using VB, but comfortable to port any C#. I want to use JQuery. I have been looking on Google, but only ever seem to find ALL checked, ALL unchecked systems.
I'm using datagridview in my vb.net project. In that datagridview I use checkbox for null value check property if the user click that how I check if the box is check or not in a number of rows and know how many check boxes are clicked also want to count. i try with my coding but it leaves the first line how I check.

i'm trying to design a program where I can take all the software that i have and just put it on an external Hard drive open this program at a customers house select what software I want to install and than let the install run through everything. I'm running into a problem with my winrar installation since I have a x86 installation and an x64 installation I want to be able to select the checkbox for winrar and than choose either the x86 or x64 and than it will install. I figured out how to set everything up it disables the two radio buttons until the checkbox is checked but I can't go through and uncheck the checkbox (say if I accidently checked it or something)[code]

View 4 RepliesI've been creating a small application and now I'm going to make a setup file for it. And I started doing this using Installshield. Here's a prtscreen of where I'm stuck: Since I've developed my Application in .Net, I don't know whether it can be installed on earlier versions of Windows such as Windows 98. Should I uncheck some options?
View 6 RepliesI use a SqlDataAdapter to fill a DataTable and then set that DataTable as the DataSource for a DataGridView. All works well. Then I add a column at the beginning of the DataGridView that will allow a user to check/uncheck a row for further processing. All works well. Then I display this to the user. All works well.
Since there are many times when the DataGridView could be displaying hundreds or maybe thousands of records, I have a button that will "Check All" records and another that will "Clear All" records. These work fine, but I've noticed a serious performance lag. Other test code that I've got shows that in an unbound DataGridView, even a large one with 50+ columns and 5000 rows, checking or unchecking all of these fields takes mere fractions of a second. (One test with 50 columns and 50,000 rows still only takes 0.334 seconds to check all of the rows.)
In my testing (with my current code), checking/unchecking 500 rows takes 15 seconds. Is this because the DataGridView is databound? If so, is there a way to UNbind it (making it simply a stand-alone set of data)? I don't need to push updates back to the server, so there's no danger in removing any databinding. I've even toyed around with this (to make the DGV unbound):

I have data grid view with checkbox as unbound column and a button at the bottom and when button is clicked i want to check all rows in the datagrid view i.e check the checkbox if it is not checked for all rows in datagridview. If button is clicked again i want to uncheck the checkbox for all rows if the check box is checked.
View 2 RepliesIt'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.

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!
View 7 RepliesI 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)

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.

I have 3 checkboxes on a groupBox, when the user presses "OK" i was first wanting to validate that at least 1 checkbox was ticked before commencing, if they haven't selected any i was going to throw an error up, i'm stuck on how to do this i'm sure a for each, but i can't seem to figure out the syntax.
View 3 RepliesI thought I could use this, to loop through all checkboxes in a frame:
For Each cb As CheckBox In Me.frameSearch.Controls
cb.enabled = False
Next
But it walks through once, then it comes with error:
Unable to cast object of type 'System.Windows.Forms.Label' to type 'System.Windows.Forms.CheckBox'.
There are indeed labels within 'frameSearch', but I thought that the "For Each cb as Checkbox" would loop only through all checkboxes..? Following does work, but it seems a bit of waste of CPU time, since it will loop through all controls!
For Each cb As Control In Me.frameSearch.Controls
If TypeOf (cb) Is CheckBox Then
cb.Enabled = False
End If
Next
How to do this more effectively?
