Binding Datarow To Textbox.?

Dec 16, 2010

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.

Binding An Enum DataGridViewComboBoxColumn To A Datarow

Jun 23, 2009

Public Class Form5
Public Enum myStatus
Pending = 0

[Code]....

The above code assumes that you have a Form named Form5 with a DataGridView called DataGridView1. If you run the form and change a value in the new column then try to exit that column, you get an exception. Ultimately I was wanting to bind from a datatable from an SQL 2000 Server which is why I used an Integer column type for the datarow. It would seem that the Enum would evaluate to an integer. If you show the valuetype in the validated event which will fire if you remove the

col.DataPropertyName = "Status"

line, It return a numeric value.

Set Some Form Controls (textbox) To Values From A Single ADO.NET DataRow?

Sep 9, 2010

I'd like to see how others might handle this scenario and perhaps provide some comments on this particular solution for handling null values. I have run into a situation where my application requires data from an ancillary source that cannot be altered/changed, which of course means dealing with poor database architecture and implementation! In this case, my app is running into errors when attempting to set some form controls (textbox) to values from a single ADO.NET DataRow. Perhaps I should be handling this when attempting to set the controls? Not sure, but here is the current way this is done:

Binding A Dataview From A Textbox?

Jan 16, 2012

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>

Binding To A TextBox Within A ListView?

Aug 14, 2011

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.

Binding Source And Textbox Not Talking?

Aug 25, 2009

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?

DataGridView Add TextBox & And Allow Edit After Binding?

Feb 20, 2012

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.

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.

Updating A Datarow With Another Datarow?

Apr 28, 2010

I have two datatables with similar structures that I want to make one existing row to be updated from another datatable.

For example, "tableA" has three columns: "one", "two", and "three"; with "one" being the primary key...

and "tableB" has three columns as well: "one", "two", and "three"; with "one" being the primary key.

Say there is a row on tableA that is different than a row on tableB (with a matching primary key). What I wanted to do, as efficiently as possible, is to take the that row from tableB and replace the one on tableA so it'll be modified.

I'm not sure if there's an easier way of doing that instead of using loops for setting the row's items.

Binding A Textbox's Text Value Setting To A Variable In Configuration File?

Jul 22, 2009

I am binding a textbox's text value setting to my a variable in my configuration file. I only consider the input from this textbox to be valid if it's an integer number bigger than 1. Right now what I was doing is letting the user write whatever he wanted in the box, and I'd only let him save the settings after calling a validation function. The problem seems to be that my binding variable in the Settings class seems to be being updated as soon as the textbox is being edited, and that's a behaviour i'd like to skip. How can I do this?
