View 6 RepliesI want to populate a checkbox field in a gridview.
I am using the Checked='<%# Convert.ToBoolean(Eval("Inactive")) %>' statement but the issue that I am facing is that in the database some records contain NULL for Inactive. If it encounters a 0 or 1 value it works fine but if NULL it throws an exception.
Kindly guide me how to populate the checkbox so that it should be unchecked even if the field is null.
I am putting together a very simple GridView, one of the columns is a CheckBox.I would like the checkbox to update the SQL table as it is checked, the field in my database is a bit field.Currently i have the following:
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Bind("Purchased") %>' AutoPostBack="true" />
</ItemTemplate>
</asp:TemplateField>
This allows the Checkbox to be checked and unchecked however it does not update my SQL Database. I have tried a couple of things but can't seem to get this to work. I am assuming i'd need to write a custom bit of VB around the 'OnCheckedChanged', i do not want an edit button on the page!
<asp:BoundField DataField="mail" SortExpression="mail" HeaderText="Com Rec">
<HeaderStyle Font-Size="X-Small" ForeColor="White" HorizontalAlign="Left" />
<ItemStyle Font-Size="X-Small" HorizontalAlign="Left" />
</asp:BoundField>
<asp:TemplateField HeaderText="Status Change">
<ItemTemplate>

Firstly i'm not asking for the exact code here but the below is what i'm trying to do:I have a gridview with DropDownList and CheckBox and I have a button outside the gridview that will add a new row within the gridview.I have no problems with the adding row but I have a problem with saving the state of the checkbox/drop down list.Everytime I checked the checkbox and add a new row, all the DDL/CB will be reset.So how can I do it so that when I add a new row, the checkbox that I've checked before will still remain check.

I am using GridView. Because of my search code I am not able to use the automatic delete function that GridView has to offer. I clicked on GridView, said "Add New Column" and added a checkbox column. I want to be able to check one or more boxes and select a button that will delete those rows from the database using a stored procedure. Below is the ASP.net part of my code

The GridView is bound to an Access Table, but I want to update the checkbox using the asp:ButtonField. The best I've been able to do is replace the checkbox with a string value. Below is the code I have now:
Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
If e.CommandName = "check" Then
'Enable Editing on the GridView

As you can see I was playing with WithEvents but that didn't seem to help. In the above code all I was trying to get was some kind of reaction to the clicking of a checkbox - but nothing happens (no errors, either).
I have a GridView with a Checkbox on the first column: Code: The thing is that the Checkbox.Checked always returns False. How can I get the checked state of the Checkboxes in this scenario? Or what would be the best approach into updating the aforementioned column? P.S. Note that click on the checkboxes doesn't post back. Nothing happens on the page until the user clicks Save (and that is the intended behavior).
View 2 RepliesI have aspx gridview with checkbox on evryrow, what is required is whenever we check any of the rows, a query should be launched to change the specific agent -each row consist of agentID, Pass, Status- to Paid Status. using javascriptWhat I need to know is how to loop to get the Checked row and get the ID of the row checked so that I can get THe ID of the Agent in thos row so that I can update its status.using javascriptI found something similar on stackflow:t GridView selected row DataKey in JavascriptBut it is not my case, what is needed is at the check of a checkbox a javascript function should launch through which I could update the selected row in grid view after having the index of this row and this all to avoid refreshing the page.

View 1 RepliesHave a unbound Datagridview with first column set as a checkbox and second column just has text.When adding a row the checkbox does not show, what am I doing wrong.Code to add Row:
DataGridView2.Rows.Add(False, FolderBrowserDialog1.SelectedPath)
The code that adds the rows also saves to a file and then there is seperate code to load datagridview at the start of the programme.If I close and reopen programme it displays the checkboxes.
objdataAdapter.SelectCommand = New SqlCommand()
objdataAdapter.SelectCommand.Connection = objconnection
objdataAdapter.SelectCommand.CommandText = "Select SerialNumber, EmailAddress, Results FROM Email WHERE SerialNumber='" & txtCriteria.Text & "'"

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.
I am assigning a 'ds' dataset to datagrid.In addition to that I want to add new column with check boxes.That new column will be first column of datagrid. Currently I am using below code,
DataGrid1.DataSource = dsResult.Tables("Result")
Result table has 4 column....in addtion to that i want to column "Selection" with check boxes
So far I have made a program that can find all the factors of a number (e.g type in 24 and you'll get 1 * 24, 2*12, 3*8, 4*6,). What I would like to do now is add a check box (called Show_Prime_Factors_chk) that when checked it will also show all the prime factors below all the normal factors.

View 1 RepliesI am trying to add a checkbox column to a DataGridView in a simple window forms application.
I am pulling back some data from a database using ADO.NET, putting into a datatable, and then setting the datagridview datasource to the datatable. I then want to add a checkbox column as the second column. So far I have this code that seems to work:
' Code here to connect to database
Dim da As New SqlDataAdapter(cmd)
Dim dt As New DataTable
[Code].....
This code 'works' and I get MyDataGridView to show the data with the checkbox column in the correct position in the table.
However, for some reason, I cannot check any of the check boxes in the DataGridView? I have tried lots of things (e.g.altering the readonly state of the column) but cannot get it to work.
I am working on a little project and am having some issues with a checkbox. I am adding a number of checkboxes to an ASP table via code by adding rows and columns dynamically. This all works fine except for when I go to check them based on loading a preexisting record. For some reason some of the checkboxes are getting set to TRUE when the new row is added to the table.
