Reading Checkbox Checkstate From Listview?

Mar 16, 2011

I'm trying to read the checkbox checkstate from the listview.Here is what i got:


The code reads ever column text perfectly but does not read the checkstate of the checkbox.Because the checkbox has no text to it.I was thinking of giving each checkbox a tag and on the click event change tag from True to False depending on checkstate. Is that a good idea or is there a faster way around this?

CheckState.Indeterminate By Mouse - Setting Checkbox State

Oct 29, 2011

I have a checkbox on my form chkActive, I want to deal with it in 3 cases. [Code] I don't have a problem with building the query, my problem is with clicking on the checkbox by clicking on the checkbox by mouse, I can only get Checked and Unchecked, I tried to use the right mouse button click, it did not fired (or I did not test deep enough) I know I can put a button to change the checkbox value to Indeterminate but that will be ugly. I can replace checkbox with combo, which is what i am thinking of doing but I just wonder: Cannot I set the checkbox state to Indeterminate by mouse any how?

Reset Checkbox Checkstate Without Triggering Checkchanged Event?

Jul 6, 2009

I'm trying to reset a form after a game has been played.  I used checkboxes to indicate when the user picked a particular line item to update and then flagged the checkbox as checked and disabled.Once all the checkboxes have been checked, the game is over and I want to show a dialog (msgbox) that will allow the user to start a new game or exit the app. To reset the form, I was changing all the checkstates back to unchecked (along with resetting other variables), but the checkchanged events are being triggered and I end up in a loop.Is there a way to change the checkstate without triggering the event?[code]....

DataGridView With A Cell That Is A CheckBox. Reading The Value Of The CheckBox?

May 15, 2011

I have some DataGridView code written in (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

Produce Checkbox Column In DatagridView While Reading From Xml File?

Oct 6, 2010

i am developing an application for generating xml file with some details inside and regenerating it whenever i need.Step1: In the user interface,i have placed a gridviewcontrol during run time. i used Datatable for building the table and assign this table as datasource to the datagridview control. last column("GHI") is a checkbox column and its is successfully viewable in the datagridview. the snippet is like this.

dim iDGVWCount as integer
iDGVWCount =1
Dim oDGVW As DataGridView


Step 3: if i reopen this xml file and populate the celll details in datagridview, the column 'GHI' is not viewable as checkbox column. it is simply shown like an ordinary cell. the snippet for opening the xml file is shown here.

dim ds as dataset
ds = New DataSet
ds.ReadXml("C: estxml.xml") 


Question1 : is there any setting needs to be done for bring back this checkbox column automatically  in the datagridview while reading from the xml file.

Question2 : how we can bring the value of unchecked column as false in the xml file. the node is included in the xml only if a checkbox is checked.

VS 2010 Listview And Checkbox's

Dec 19, 2011

I have a system which stores fee's paid for a youth teams players.A textfile stores:player name|trainingsessionsattended|amountpaidin..Each line is a new player's entry.I need to make a form that allows the user to input the amount paid by each player at the end of a training session.I did think of doing a single dropdown box and allowing the user to select a user and enter how much he/she paid and entering each players fee's one by one. But this is not practical, considering there are 20 players, this may take a while.I thought of having a listview with every players name and then using this to add the players fee's but am not entirely sure how to go about this.

Reading 'Checked' Property Of Dynamic CheckBox On Page Postback

Dec 29, 2009

How can I check the 'Checked' property of a dynamically-created checkbox during the Page_Load subroutine? Basically, I have a VB.NET page that creates some table rows dynamically, based on a number selected by the user. So, for example, if the user selects "3" from a dropdown list, the page posts back and creates three table rows. Each row contains a couple of textboxes, a dropdown list, and a checkbox (which are all .NET form controls rather than plain HTML controls, I should point out).Typically, the user would enter a few details into the form controls, and click the 'Submit' button, after which the page iterates through each row, and inserts the data into a SQL Server table.But if the user ticks the checkbox for that row, this signifies that the page is to ignore that row, and NOT insert that row of data into the database when the user clicks 'Submit'. This works well, but there is a problem. If the user clicks 'Submit' and some of the values entered into the form controls are invalid (so, for example, the user didn't enter their name) then the page won't submit the data, and instead, shows an error to the user informing them of the values they need to change. But if the user creates three rows, for example, but decides to "ignore" the third row (by ticking the checkbox) then when the page posts back, finds some invalid entries, and re-shows the form to the user to allow them to correct any errors, I'd rather the page didn't render the third row altogether. After all, they chose to create three rows originally, but then decided that they only needed two. So it makes sense that the third row is not recreated.

But what seemed to happen was that objCheckbox.Checked was always returning False, even when the checkbox was ticked. Once the page had loaded, the table rows had rendered again, and the tick was present in the checkbox, so it's not like the value was lost on postback. But at the point I check whether the checkbox is ticked, it always returns False, rendering a table row that the user doesn't need.Does anyone know how to get round this problem? I've read lots of articles about the .NET ViewState, and the page lifecycle, but I've yet to find a solution that works. I simply need to be able to check if a checkbox is ticked before re-creating some dynamic controls. [code] But then I basically found out that you can't override a protected member with a public one.

VS 2008 Make ListView Checkbox?

Feb 5, 2010

I've created a basic form, entering the name and song of an artist. They can select a priority (1, 2 or 3) and it will drop the information into seperate columns of a listview. Based on the priority, the row is assigned an image in the item field of either an up, rgiht or down arrow. This works all fine. I selected the checkbox function to true and it places checkboxes next to every image as planned. However the checkboxes are just the arrows. If you click the 'checkbox' it keeps cycling through the 3 images.

How do you disable additional checkbox selections/deselections without sacrificing the functionality of the ListView? I know you can call: ListView.Enabled = False, but that also disables any scrolling within it.

For example: I have a timer that starts a backup based on the Listview items that are checked. After a certain time, I don't want the end-user to be able to click on any of the checkboxes within the listview (so I have a set number of items to backup), but I do want them to be able to scroll the list while the backup is being performed. I tried this[code]...
