Using A Checkbox Outside Of A Datagrid To Affect Its Contents?
May 21, 2012
I am using a Checkbox outside of a datagrid. When i select the check box autopostback is true, and this would then show the image, but i cant access the images within the datagrid with that script. If i use a seperate image outside of the datagrid the script works. How can i get this script to work finding when the checkbox out side of the datagrid is checked to then show the image within the datagrid?
The script i am using is
<script runat="server">
Sub Check(sender As Object, e As EventArgs)

I decided to rewrite my project. Hit another snag. How do I write the contents from a datagrid to a file and back into the datagrid again later? (Actually, I've done the writing ok - but for the life of me can't get the data back into a blank datagrid.
Here's what I done so far:
Imports System
Imports System.IO
Imports System.Text

I have a datagrid who's ItemsSource is a strongly typed IEnumerable object In this datagrid, I have a checkbox column, a price column, a part name column, and a 'total selling for' column. On checking the checkbox I need to update the total selling for column with the value in the price column. This part I have working, however, how can I get the checkbox to remain checked when this happens?
Private Sub UpdateSellFor(sender As System.Object, e As System.Windows.RoutedEventArgs)
Dim _CB As CheckBox = DirectCast(sender, CheckBox)
Dim _ID As Integer = _CB.Tag
Dim _PP = DirectCast(DG_PartsToSelect.CurrentItem, PartTyping).PartPrice

I am using the following code for a checkbox, if checked it should print the text defined, unchceked, it clears the items in the ricktextbox. My problem is it prints fine (lets say it prints two lines) as defined, when I uncheck, it clears the text in rich text box, but when I check again, the text appears in the richtext box, but displayed from 4th line. I need to restart from the beginning/ or at least from the next available line. I cant use clear() since it erase all the contents as i have another 3 checkbox items placed.
If CheckBox1.Checked Then
richtextbox.SelectionColor() = Color.Blue
richtextbox.AppendText("Urgent:")
richtextbox.AppendText(CheckBox1.Text.ToString + vbNewLine)
Else
richtextbox.Refresh()
End If

I am working with Vb.net. See the code below; I have the following problem - when I click the checkbox (Cells(3)) the value remains 0.00 in Cells(4) unless I click another checkbox is when Cell(4) gets populated with the value from Cells (5).
What I want it to do is when cells(3) is checked, Cells(4) should be populated instantly with the value from Cells(5). Rather than still show 0.00 until another checkbox is clicked. I think th eproblem is in the eventhandler as highlighted

Is it possible to transfer the contents of a row in a datagrid to a textbox? (Like, when I click row 3, the contents of that row will be transferred to the textboxes) If it is, can anyone guide me to a tutorial? Or is this technique applicable only to the ListView object?

I am limited to using ASP .NET 1.1, as for this environment I cannot upgrade to 2.0 or beyond Essentially, I have a very simple datagrid that has a checkbox in one of the columns, which is a template column...the code for the datagrid is this:
<asp:datagrid id="dgDates" OnItemCommand="gridEventHandler" BorderColor="Black" BorderWidth="1px"
CellPadding="3" runat="server" AutoGenerateColumns="False" HorizontalAlign="Left" AllowSorting="True"
OnSortCommand="SortData" OnItemDataBound="gridItemDataBound">
[code]....
Now, my issue is that when I set cbStaticRolling to the CheckBox control through FindControl on the e argument, it seems to set the variable okay, but doesn't seem to be setting the right one, or setting it properly, because "Checked" property is false regardless of whether I check the box or not?

I have a tbl called tblProjectpatients which also has 2 fields Yes and No (these have the data type - Bit).
These two fields have been populated with false and true values.
On my form, I have a datagridview which is populated with various values from tblProjectpatients.
The problem am facing is that the checkbox's for Yes and No on the datagridview are empty at runtime eventhough at the backend they have either False or True values.
I am expecting the checkbox showing on the datagridview to be either checked or Not Checked depending on the True or false values.

I haven't seen a related thread (yet)I have a VB windows application that uses a datagrid to display a text column and a checkbox column. Only one row in the display can have a checkbox entry = true. If a checkbox is selected, the app is to search the rows and all other checkbox entries are to be set to false.My event handler is: Private Sub dgMember_CellContentClick(ByVal sender As System.Object, ByVal e As ystem.Windows.Forms.DataGridViewCellEventArgs) Handles dgMember.CellValueChangedI first had to have this handler code check a flag and exit if true (when initializing the display) because it was called for each row during initialization.

Interesting problem. I have a datagrid with several columns which are bound to an Access database. Here's the situation...I'm concerned with the 3rd column.This is what I'd like to happen... when the 3rd column(is a checkbox) is checked then column 4(TIME_USER) would be populated with the current time
Basically, this application is meant to keep track of tasks that the user has to do at a certain time of the day. When the user checks the checkbox it would record the time in the database for that task as to when they did it. I found some code from a forum that i changed to fit my needs, but it's not working.

I'm writing an Windows Form Application and need to add an unbound checkbox to a datagrid.The datagrid displays the fields of an Access 2007 table and I need the checkbox to give the user the option to select/deselect any of the records shown in the datagrid. After the user clicks on a button, the application must read the whole datagrid to detect what records were chosen by the user and process each one accordingly.I tried using TableStyles but as this new column is not part of the database, it won't work.

I have a datagrid, with an unbound checkbox column. How can I get a range select use shift and ctrl keys that will check the checkbox?The moment you check a box, it selects only that row, so the rows selected are down to just the row you clicked on. I've been playing with several events and settings and I can't seem to get it. Can anyone point me in the right direction?When your problem is solved, add (RESOLVED) to the end of your topic. This will save the guru's time and be able to solve more problems. Remove the question mark icon as well.

I've got a DataGridView control that is bound to a datatable. The first cell of each row in the DataGrid is a checkbox. When the screen loads all of the checkboxes are unchecked by default. I have a "Select All" button to check all of the boxes. This is performing very slowly when I have a large number of rows in the grid. If I have 1,000 rows it takes over 30 seconds for them all to be checked. When I had 5,000 rows I gave up after 5+ minutes with no result. To check all of the boxes I am looping through each row of the datatable and setting the first item to True:
[code]...
Since that yielded such slow results I changed the logic to loop through each row of the datagrid and set the cell to True but that took three times as long.
Is there a way to quickly "check all" on a large set of data?

objdataAdapter.SelectCommand = New SqlCommand()
objdataAdapter.SelectCommand.Connection = objconnection
objdataAdapter.SelectCommand.CommandText = "Select SerialNumber, EmailAddress, Results FROM Email WHERE SerialNumber='" & txtCriteria.Text & "'"
[code]....
What I want to do is for every row of data in the datagridview, i want to add a column for checkbox. The checkbox will be enabled or disabled based on the value found in the field results. The first time I am pressing the button, it works fine. But the second time i query, it keeps adding another checkbox to the same row. Even for the nth time. Everytime i press the button, a checkbox is added. I just want one checkbox every time i query the dataset.
