Dynamically Binding To Datagrid

May 3, 2012

I'm trying to bind a dataset to a datagrid. I've found many examples online... all look similar to below. My problem is that the bind seems to work, but nothing shows on the datagrid. It's blank. Both rowcounts in the message boxes display the correct number of rows for both the dataset and datagrid. Does something need to be initialized in the datagrid properties?

Asp.net - Creating A Table And Binding To Repeater Dynamically From Two Database Tables?

Nov 1, 2011

I am working on a CMS system for my business, and need to be able to generate notifications dynamically into a control panel. Please note, I am using .NET 2.0, coding with VB and my data is all held on a MySQL database.This is pretty simple for most aspects, but as the whole thing is dynamic some things are proving more difficult.I have a set of tags which are dynamically generated with a repeater as follows:

<asp:Repeater runat="server" ID="locationRepeater">
<ItemTemplate>
<p id='locationNotification' title="<%# Container.DataItem %>" runat='server'>
COUNT DATA NEEDS TO GO HERE
</p>

[Code]...

The data is really, really, simple, all I need to be able to do is query a table on my MySQL database for COUNT of ID WHERE locationName = Container.DataItem during each loop of the repeater... but I don't know how to do this.I'm thinking maybe I have to do this first, create a table in memory somehow, but I am afraid I have no idea how to achieve this.

Has anyone got any examples of a similar thing, it's kind of binding to a repeater from two datasources... each task is very simple, but I don't know how to put it all together!

Binding Controls To A Settings File?

May 9, 2012

I want to be able to control several groups of settings independently of each other. I'd originally used My.Settings, but it was too much work to manually rollback some settings whilst saving others.

I thought my solution was to use multiple settings files, and I've had moments where this seemed to work, but I whatever success I have had is periodic and temporary.

Currently I have two settings files in the root of the project; In code, I can access the settings OK, but in many cases I want to bind individual settings to controls. This should be straight-forward, and I recall it working when I used the single, built-in settings file.

However, when I use the two new settings files it doesn't work. In the Formatting & Advanced Binding dialog, I select Add New Project Data Source, I browse into my project, then into the root namespace, and then I see my forms/classes/settings files. When I select the two settings files, and click OK, the dialog is dismissed without me being able to select an individual setting to bind the control to.

When I enable Project > Show All Files, I can see that the binding has been created; I have two .datasource files under My Project > Datasources.

Is there some reason why I shouldn't be able to bind to these settings files? If not, why can I not access them the the data-binding dialogs?

Plan B is to create an object to act as an intermediary between the controls and the settings files, but I'd rather avoid this if I can.

Binding Validation Controls In A Datagrid?

Feb 15, 2012

I have the following datagrid:

<asp:DataGrid runat="server" ID="gastosReembolsables" ShowFooter="True" AutoGenerateColumns="False">

<ItemStyle CssClass="DATAitem1"></ItemStyle>
<HeaderStyle CssClass="DATAheader"></HeaderStyle>
<FooterStyle CssClass="DATAitem1"></FooterStyle>
<Columns>

all bindings work except the ones in the validation controls for the itemtemplate of the last column (they are passed as text to the web page). Why is this happening? is it even possible to do what I'm trying to do?

C# - Binding Controls To Class Properties?

Mar 20, 2009

I have yet to find a "nice" way to do two way databinding in .Net. The one thing I don't like for example in the present asp.net two way databinding is doing the binding in the aspx page is no compile time checking, ie:

<asp:TextBox ID="TitleTextBox"
runat="server" Text='<%# Bind("Title_oops_spelled_wrong") %>'>

I would like to have something like this:

Class Binder
Public Sub BindControl(ctl As Control, objectProperty As ???????)
'// Add ctl and objectProperty to a collection
End Sub

What I don't know is possible is, how to receive the objectProperty in my example; I want to receive a reference (ie: a pointer) to the property, so later, via this reference, I can either read from or write to the property.

Can this somehow be done with delegates perhaps??

UPDATE: Note, I want to add the control reference to a binding collection, this collection would then be used for binding and unbinding.

Forms :: Data Binding To Hidden Controls

Apr 21, 2009

I have a windows form that I bind to a datatable via a binding source. The binding is done in code at run time. Eg;Me.txtCode.DataBindings.Add(New System.Windows.Forms.Binding("Text", bsForm, "ToolCode", True)) (bsForm is the binding source)This works well except if the form control is hidden (I have a couple controls on the form that hold Record ID and Version numbers that the user doesn't need to see). Databinding doesn't seem to work reliably for hidden controls.

Using Data Binding Controls To Add Records To DataSet

May 2, 2011

I need to add rows to a DataSet using databound controls in VB.net. I've set up the data bindings themselves, they're bound the the correct controls, and the BindingSource uses the correct DataSet. The DataSet is filled from the DataAdapter correctly, and the binding source works, as the navigation controls all work fine. How do I use the controls to add new data to the DataSet? I guess there must be some kind of end-edit involved which would enable me to insert, update and delete records in the DataSet (as you would use with DataGridViews)

Asp.net - Dynamically Added Controls In .net?

Jan 15, 2010

I understand the page lifecycle and how i need to add the dynamic controls on page_init if I want to take advantage of viewstate. Also I know that I should try to avoid dynamic controls when possible. The dynamic controls are created depending on an object that is created from custom event arguments sent from a custom treeview. Problem is I need viewstate so I need to create them in page_init but I don't have the event args to create the object that tell me what controls to add until later in the lifecycle.

Private Function GetEventArgs() As npTreeViewEventArgs
Dim control As Control = Nothing
Dim e As npTreeViewEventArgs = Nothing

[code]....

I use this in page_init to create my object and controls.

Dynamically Arranging Controls In .net?

Jun 21, 2010

I am looking for the best way to dynamically arrange the location of labels (or any control for that matter) during runtime in a Windows Forms application using VB.net or C# in VS2008.I have a control that displays messages created by users.This control has a panel docked at the top which holds the header information for each message, called pnlHeader There are 8 labels: 4 of them display static descriptions (e.g. "To", "From", "Created Date", "Completed Date")And the other 4 display the relevant data for those descriptions. (Passed in during runtime from a MS SQL 2005 DB).Static labels are named: lblCreatedDateLbl and dynamic ones: lblCreatedDate The application runs on monitors of various size and resolution, therefor I would like for all of the labels to arrange themselves with equal spacing in pnlHeader, based on the current width of the panel.

At first, I had simply created the labels in the Designer and used Anchors (half of the lables were set to (Top, Left) and the other half to (Top, Right)). This solution worked for most scenarios, but did not always provide a consistent solution, so I decided to add the controls in code instead.

I thought it would be easier to work with the labels by creating a panel for each corresponding pair. So pnlCreatedDate would hold lblCreatedDateLbl and lblCreatedDate I wrote 2 methods: 1 to define each label and add it to the relevant panel: Sub AddLabels
and another to determine the width of the panels and set the correct location: Sub SetLoc Currently, AddLabels runs in the constructor after InitializeComponent() and SetLoc is called after the data has been passed in from the database.

I've tried making minor changes and tweaks to the width and size parameters, enabling and disabling AutoSize, but nothing returns a consistent solution, instead either all the description labels are misplaced, or do not appear at all or completely whack locations come up.

Private Sub AddLabels()
'Label Created By:'
lblCreatedByLbl.Location = New Point(0, 0)

Output Propagates Across Multiple Controls When Using The Same Binding Source

Aug 16, 2011

I have SQLdb column elements from one table that are selected from another table. This is achieved through the use of binding a combobox to the selectable entries and applying that entries ID to the initiating table column When I add multiple combo boxes, for multiple columns, the data selected propagates across all the combo boxes I have. They all use the same binding source. It seems to me the only way out of this is to create a bunch of binding sources, essentially one for each control. I have tested this and it appears to work, but is there another, less cluttered way of ensuring that the comboboxes, while bound to the same binding source, are not bound to one another?

Control Recommendations - Controls At The Top Of It And A Large DataGridView Is Docked Below All The Controls

Nov 10, 2011

I have a maximized form that has controls at the top of it and a large DataGridView that is docked below all the controls. Its kind of like the Ribbon in MS Office. The controls cover about 1/4 of the screen at the top. I would like a way for the user to click a button to hide all the controls then automatically expand into the place the controls were so the user can view more data in the DataGridView and visa versa. For example, in MS Office Excel you can hide the ribbon by clicking a tiny button that has "^" on it.

I'm not very familiar with all the controls in Visual Studio so I would like to hear some recommendations. Is this situation ideal for a SplitContainer or ToolStripContainer or am I way off base here?

Adding Controls To A Panel Dynamically?

Jun 10, 2011

I am working on a project for a handheld in Visual Studio 2008 where I need to add a group of labels to a panel that correspond to a record on the database. The record is a "Pass/Fail" Record. So, if the record is a "Fail", the failed items will be added below the main group of labels; therefore, many child groups of labels will be added below the main group, which is theoretically the header record. I am using a second panel to add the failed items. My issue is how to dynamically add, name, and position the failed item labels and panels. Below, I have included a sample of what I am trying to accomplish.

Asp.net - Loop Through Dynamically Created Controls

I don't know why but when I am debugging I have a count of 50 controls in pnlTeacherSelect right up until I press the button that calls prcChoose.

Asp.net Mvc 1 Validation Using Dynamically Created Controls

Aug 11, 2010

Using ASP.Net MVC1 and am dynamically creating the html in a model that is then dropped into the view and rendered at run time.

My view is a single page that looks like this:

<%@ Page Language="VB" Inherits="System.Web.Mvc.ViewPage" %>
<%=(ViewData("Content"))%>

This dynamically created content is mostly dropdownlist boxes in the format of

<form method=post action="/questions/nextBatch">
<div id="text">What is your preferred drink?</div>
<select>

[Code]....

Is it is possible to perform validation on the dropdowns lists to ensure that a value has been selected? If any of the dropdownlists that still have the default value (the "please make a selection" text) the page is then redisplayed with the font colour of the question or dropdownlist box changed to say red?

I'm from the Webforms world and have made the switch over to MVC (which I really like!) and I know there are some pretty slick validation tools out there but you seem to have to account for them within the view itself.

I cannot pass a HTML helper through the viewdata of the controller as it does not render unless it has been coded directly into the view itself.

Also, I'm looking for a pure asp.net solution as I cannot use javascript due to accessiblity concerns. I can access all the values of the dropdowns without any problems throug the formscollection object but from there I'm a bit stuck.
