Simple Checkbox Binding Without Using A Textbox
Jun 11, 2011
I Have a question about binding (pageID + PermissionID) to a checkbox/ checkboxlist, without using a textbox or any other tool. The thing is, i'm working on something just for exploration is it possible to have multiple checkboxes all bind to a different pageID but all have same permission. (lets say the permission is view-only) So when some checks a checkbox with ID 1, ,5,9,19,56 he gets view permission to those pages. when he uncheckes then they get deleted.

I have developed a form for Windows VB.Net that uses a number of text boxes that are indidivually bound to separate columns in a database. When one of the textboxes (let's call it XYZ.Text) is bound to the database, it prevents the data from any of the other bound text boxes to enter the database. When the binding for this one text box (XYZ.Text) is removed, then all the other text boxes work fine.

I've got a datatable in a dataset binding to a datagridview. One of the columns in the datatable is called status, but it is a type string. It can be "0" or "1". On the datagridview, i want to bind it to a checkbox. if checked, it must put a "1" in the datatable and if unchecked, it must put a "0" in.

I have an DatagridTemplate Column containing an Checkbox which through an converter gets checked when a property on my ItemSource is "J" and unchecked when the property is "N".This works, but now I want the property to be set to "J" if I select the checkbox or "N" when I deselect it.
My Column:
<local:JNConverter x:Key="JNConverter" />
<DataGridTemplateColumn Header="">

I am trying to create a basic webpage that will check a column of a database table to see if a "UPC Code" is taken already, to prevent duplicate use. I'm fairly new at .NET programming, but have built asp pages before. I'm just stumped :/
I have a textbox that a user can type in a number. The page successfully checks to see if the textbox is blank and reports the error, and if there is a value, it's supposed to bind that textbox number to a gridview to see which Item# it's associated with. But for some reason, my code is not binding the value of the textbox to the gridview.
Code:
<%@ Page Title="Home Page" Language="vb" MasterPageFile="~/Site.Master" AutoEventWireup="false"
CodeBehind="Default.aspx.vb" Inherits="UPC_Checker._Default" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
</asp:Content>

I have the following code where I'm trying to bind a datarow to a textbox.
Me.TierNameText.DataBindings.Add("Text", Me.m_TierRecord, "tier_name") Problem is, when the form is displayed no text is shown in the textbox.
This code runs before I call the form's ShowDialog method. I stepped through the code to make sure the datarow has data, and indeed it does.
I rarely use databinding but thought I'd try it this time.

I have been searching for an answer for this for almost a week now, and I can't seem to find a way to do this. I would think it is a relatively simple thing...
I have a ListView, and one GridViewColumn contains TextBox items. I want to put a Label right underneath the ListView, and fill it with the sum of the items in all the TextBoxes. Whenever someone changes a value in any of the TextBoxes, the sum should change, too.[code]...

I am running Windows 7 and have an application that has a textbox bound to a Property in a Custom Class that Implements IEnumerable.When I call Raise Event to update the textbox it will only work the first time.However, the application works on every other OS I have tested on (XP, Vista). Also if my custom class does not implement IEnumerable it works correctly.Is this a bug? Am I doing something wrongform with a textbox and a button. The Textbox is bound to the Total Property in the class.

Im having some wierd behavior on a bound form in vb.net 2008. I have setup a client form, with another tab that has contacts for that client. the contacts tab has a binding navigator at the bottom, so the user can move amongst the contacts. all fields on that form are bound to a bindingsource called bsContact, using a table adapter called "ContactTableAdapter"
if i have a contact already saved, and want to modify the contact info, the form binding doesn't seem to recognize that i have changed the value of a textbox on that contact.i would think that if a textbox is bound to a bindingsource, then if the value of that textbox changes, the bindingsource would know about it, but it doesn't. The dataset.HasChanges returns false, and my save wont happen. (see code)so, when i hit the movenext on the bindingnavigator, it changes to record 2...i change a value on a textbox...i hit the save button on my form....no update will happen.
Update: I noticed that if i am on the tab with the multiple contacts, and i change a textbox on the form, then i MOVE TO ANOTHER RECORD, then the dataset recognizes that there was a change, and the update happens. Why doesn't the textbox immediately notify the dataset that a change is happening?

I'm unsure as to how to take two pieces of information from a table and display them into a textbox. The textbox should display the 'Balance' and the total money available for withdrawl (balance + overdraft limit). I believe I need to use the data bindings command e.g. TextBoxDetails.DataBinding.Add?

I have one DataGridView named dgv.dgv is pretty much a plain gridview. No bounded data. No columns added. It's basically empty.I also have one DataTable named dt.I add rows and columns manually into dt.
dt.Columns.Add(New DataColumn("TexBox", GetType(String)))
dr = dt.NewRow()
dr("TextBox") = String.Empty
dt.Rows.Add(dr)
I then simply set dgv datasource into dt.
dgv.DataSource = dt
dgv.Refresh()
I then set the value for this particular cell.
dgv.Item(0,0).Value = "xxx"
Now when I run and execute all those commands. I happen to retrieve the gridview with that value indeed. The "xxx" cell appeared and currently it's uneditable.What I want to achieve is:Allow this "xxx" cell to be editable. Preferrably if it can be inserted into a TextBox control inside the cell.

Basically, i don't want to use <input type="submit"> mainly because it's a button, i'd rather user ActionLink, so i am using Ajax.ActionLink, and i'm not sure what to place in the routeValues argument for it to pickup the new (edited) data (user enters comments etc) and send it to my action.this is what i have, but of course, it sends the original comment before user edit back to the server/action :)
<%= Ajax.ActionLink("Update", "UpdateComment", Model.Comment,
New AjaxOptions With
{.UpdateTargetId = Model.CommentDivId, .HttpMethod = "Post"})%>
ps: i know how to do this in javascript, and doing ajax posts etc,
