I am having an issue with gridview and checkboxes in asp.net. I bind the grid at page load and add Attributes to the checkbox in the BindGrid() function:
chkSelection.Attributes.Add("onclick", "AbortPostBack(); __doPostBack('" + chkSelection.UniqueID + "','');")
AddHandler chkSelection.CheckedChanged, AddressOf ChkSelector_CheckedChanged

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).
There are lots of questions about this but I've not been able to solve my problem using the answers to any of them (after many, many attempts..)

I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

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

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 6 RepliesWPF: Display a bool value as Yes / NoI'm writing a WPF program in VB.Net 2010 (.NET 4.0) that uses data binding against a simple class that is an ObservableCollection of another simple class I've written. So far I have a DataGrid that shows the information and I can add and remove items as necessary, but I seem to be stumbling with a fairly basic concept:How do I display data in some way other than the default behaviours that the various DataGrid columns allow?I have a boolean called "reversed" in my original class, let's call it "x". I would like the DataGrid displaying the ObservableCollection of "x" to display "Yes" or "No" under the Reversed column instead of a checkbox that is checked or unchecked (DataGridCheckBoxColumn).

View 8 RepliesI'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.
