DataGridView With A Cell That Is A CheckBox. Reading The Value Of The CheckBox?
May 15, 2011I 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)
[code].....
I've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.
Reading Checkbox Checkstate From Listview?
Mar 16, 2011I'm trying to read the checkbox checkstate from the listview.Here is what i got:
[code]...
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?
Produce Checkbox Column In DatagridView While Reading From Xml File?
Oct 6, 2010i 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
[code]....
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")
[code]....
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.
Reading 'Checked' Property Of Dynamic CheckBox On Page Postback
Dec 29, 2009How 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.

Refresh Checkbox - Getting The Checkbox Unchecked For The 2nd Address?
Jun 30, 2009I've got a form with parent-child setup. The parent displays name and other demographic info.The child displays multiple addresses, one row at a time. There can only be one primary address for a name and this is designated by a checkbox at the top of the child form.If the user wants to change the primary address to another address,then they find the other address and click on the checkbox.The form checks the other addresses and if one is found that is designated as primary,the user is warned that one already exists and prompts them to change it.
So for example, a name has 2 addresses, the 2nd being the primary address.The user wants to change the 1st address to be primary.They click on the Primary Address checkbox for the 1st address.A warning displays that there is already an address listed as primary.The user then answers the prompt to change the 1st address to the primary address.The checkbox for the 2nd address will be unchecked and the checkbox will be checked for the 1st address.My problem is getting the checkbox unchecked for the 2nd address.If I close the form and reopen, then the checkbox is unchecked.How do I refresh the checkbox for the 2nd address?Here is the code I'm using to find if an address has already been marked as primary:[code]......

I am trying this:

Oct 13, 2009My DGV has MultiRowSelect = True
I have 4 things I am trying to overcome when loading the DGV and when clicking on a row.
1. When the DGV loads, the first row is Selected by default. I would prefer that it not be since that row may not be needed to be selected and mistakenly left selected.
2. Column(0) contains an UnBound CheckBox, when I click it, I want the row to be Selected
3. When I click on the DGV Row, I want the CheckBox to be marked either True or False depending on the state before the row click and the row selected or unselected.
4. Bypassing the need for Ctrl or Shift to select multiple rows.

This is creating a whole new row into the database, i also need this check/uncheck to be recalled according to the row.

View 37 RepliesVS 2008 CheckBox Always Believes It Is Unchecked?
Oct 3, 2010I have a very stubborn check box . Let me tell you its story :There is Form1 with a button leading to Form2 . On Form2 there is located that stubborn check box I was telling you about . That check box has code in its CheckedChange event and accordingly to its Checked condition , it enables or disables some text boxes .Well , the first time Form2 is shown , that check box works fine : when I check it it enambles the text boxes and when I uncheck it , it disables those text boxes .Then , I press the button to return to Form1 . If needed , the code in the button is :Form1.ShowMe.CloseMy adventure starts when I show again Form2 ... This time the check box is acting weirdly . No matter if I check it or I uncheck it , it always disables the text boxes , as if it is constantly unchecked ! I can see it changing its checked state whenever I click on it , but it always runs the code to disable the text boxes.
I even used some break points in the code and found out that indeed it is the code that disables the text boxes that is called every time , no matter if the check box is checked or unchecked .I don't thing this has anything to do with the fact that this event is called by all the 4 check boxes on the form . After all , it is always the 1st check box that causes the problem (I can see it when moving the cursor over the genericindex variable) .
