Programmically Update A Bound Checkbox In A GridView Using An Asp:ButtonField In ASP.NET 2005?
Jan 6, 2012
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
[code]....

On a Windows form I have a checkbox bound to a datatable. In the CheckedChanged event I do .EndEdit on the bindingsource and then .Update on the tableadapter. At runtime this gives an error: "Data Table internal index is corrupted: '5'.
If I change to the Validated event, there is no error, but the new state is not sent to the data base untill focus is subsequently lost, which is a problem. So how am I supposed to get the new state of the checkbox written to the database when the checkbox state changes?

I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page:
<asp:SqlDataSource ID="msgUnread" runat="server"
ConnectionString="<%$ ConnectionStrings:edinsec %>"
[code]....
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 don't think this can be that hard but I just can't get my head on it. I have a connection to an Access DB, put three text boxes representing three columns in the DB. Using the DataNavigator everything works. But what I want is to be able to enter text in say textbox1 and have textbox2 and 3 update, like when using the navigator.
Add: I want this to function like when you enter a record number in the Navigator and hit Enter, bam, goes to that record and all the text boxes update. I want to enter a number in textbox1...

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'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page.
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...

I'm seriously about to abandon this DataRepeater. I don't want to. I want greater design control than the DataGridView. I've played with various Events for days and have settled on the CheckBox.CheckChanged Event.
What I'm trying to accomplish: My Bound DataRepeater has an UnBound CheckBox in each DataRepeaterItem.When the user 'Checks' the CheckBox, I want to change the value of a NumericUpDown Control to the value of a hidden, Bound Label.
[Code]...
This causes other, seemingly random, DataRepeaterItems (Rows) to also become Checked and thus it's NumericUpDown value to change.Am I going about this from the wrong angle? Can't see the forest for the trees?

I have tried to set up combo boxes in the gridview but all the combo boxes have the same value in them instead of the value from the database. I am using entity framework and WPF. There is a parent child relationship between two tables but the source for the combo box is a separate table with names and IDs for tags. I have been looking all day. Hopefully this won't be too easy to solve.
The "Tag" Column displays the combo box. The Column "Tag ID" displays the value from the database. When I display the data the TagID Changes in diffrent rows but the Tag column is the same (the first choice) in all the rows. When I change one combo box they all change. I can't see where they are hooked together.
Here is the XAML
<Window x:Class="MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="372" Width="675" mc:Ignorable="d"

I have a gridview in asp.net/vb and it is bound to a list - so there's no standard sorting available. I've found this jQuery plugin for sorting tables: [URL]. The plugin requires <thead> and <tbody>. The problem is, that my gridview only renders the <tbody>.
I've already tried
DataList.UseAccessibleHeader = True
DataList.HeaderRow.TableSection = TableRowSection.TableHeader
But this changes nothing.
My gridview markup:
<asp:GridView runat="server" CssClass="grid" ID="DataList" AutoGenerateColumns="False" AllowSorting="True" ClientIDMode ="Static">
<Columns>
<asp:BoundField HeaderText="SomeHeaderText" DataField="SomeDataField" />
<asp:BoundField HeaderText="SomeHeaderText" DataField="SomeDataField" DataFormatString="{0:dd.MM.yyyy}" />

I am creating a simple website using the language of VB.NET, I am having trouble with one part at the moment and could really use some help.
At the moment I have items that are stored in a database, when the homepage loads these items are added to a Gridview which allows the user to select the items they wish to add to their shopping cart. Once an item is selected from the gridview it is added to a collection. That collection is then added to a Session. This is the code I have for completing that task.[code]...

I have a GridView control which I am dynamically binding to a DataTable which is populated by a query built based on a set of selected options.What I am trying to do is simply handle the RowDataBound event in order to format specific rows based on the value of a database field. The code in this event handler works fine. My problem is, calling this event causes the GridView to only display the first record in the DataTable, almost as if the Gridview stops after binding to the DataTable after the first row is bound. I have attempted adding the handler dynamically, but I get the same results.I know for a fact that there is sufficient data being returned (the DataTable fills with all of the records, and the GridView shows all the records fine when not touching the RowDataBound event).
I'm adding the handler immediately after generating the query, filling the DataTable, and binding the GridView: [code]I have also determined that, when handling RowDataBound, the GridView's DATABOUND event never gets fired; it seems to stop binding right after binding the first row.

I have a gridview that is bound to a datasource (Windows Forms, VB.NET). One of columns is a property of type boolean, and I want to show "yes/no" in the column instead of 0/1 or "true/false". Is this possible? Can you edit displays of columns that are bound?

I have a gridview that is bound to a datasource on a Windows Form (VB.NET). The grid displays a list of "certifications", and each "certification" can be associated with many languages. So in the grid, I'd like to display "languages" as a column, and display a comma delimited list of the language names for each "certification".
In the "certification" class, one of the properties is a list of "language" objects, and each "language" has an ID (guid), name (string), and value (integer).
So in the datasource, I have the list of "languages", but I can't figure out how to display them in a column on the grid. The gridview won't let me add the language list property as a column.
So is the ONLY way to add a new property on the "certification" class, which returns a string that contains the comma delimited list, and show THAT on the grid? Or is there a way to display that list of "languages"?

I have a gridview that is set to a sql datasource, it is generating the columns automatically. If I add a column to the table it is referencing, it will draw that column and display it, but it does not update the insert/update commands to include the new column. Is there any way have it rebuild those commands automatically?

I have a datagridview bound to a table adapter. It displays data just fine. Part of this data is a comments field. When a user wishes to edit this I open a seperate form with the data in a a text box. After the user edits this text, how do I update the database / datagridview?
I can update the datagridview cell's value but that doesn't propagate to the database until the focus is removed from the row. I tried BeginEdit and then EndEdit (which should commit) but apparently it needs to move to another row!

I 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!

I have a DataGridView bound to a DataTable. Although all rows are displayed in the grid, the table represented by the Grid's DataSource does not get updated after changing values in one or more DataGridView columns. Both grid and table contain a Primary Key. What am I missing here? Do I need to do something in the RowValidated event?
dgvCriticalContacts.AutoGenerateColumns = False
Dim ccRs As DataTable = Common.OpenRecordset("SELECT * FROM PhoneList")
