Make Gridview Checkbox Field Update Boolean Field In Database?
Feb 7, 2011There 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...
Asp.net - Bind Dictionary To GridView?
Apr 30, 2012Algorithm to count the time that occured on the same period, how to bind the dictionary to the GridView? Pls take a look to the answer.
I tried to add a GridView and then on the code-behind: GV.DataSource = timeRangeCounts and bind it, but in return:
The data source for GridView with id 'GV' did not have any properties or attributes from which to generate columns. Ensure that your data source has content.
take a look at the code below:
The first helper class is used to hold the counts of exact and sub range matches:
Public Class TimeRangeCounter
Property ExactRangeMatch as Integer
Property SubRangeMatch as Integer

Apr 1, 2011If I have the following ASP.NET code (it's not complete - obviously there's a lot missing, but none of it matters):
<asp:GridView>
<Columns>
<asp:TemplateField>
<ItemTemplate>

How can I bind the GridView so that one row is equivalent to one item in my MyListOfObjects list, and so that the data will populate and persist across page loads or postbacks? I've never done custom databinding like this before, so a full explanation would be very helpful. All the tutorials I've come across so far only talk about using GridViews directly with Database query results, and that's not what I need.
Asp.net - MasterPage Data Bind To GridView?
Jun 14, 2012I have a Master Page with nested pages in ASP.NET. Fairly simply I want to databind some hyperlinks to a gridview for the master page. This however is throwing a null reference exception when I try to set the DataSource.
I tested the code on a separate page and it works as expected. When debugging I can see the Page_Load Sub hit twice, I don't know if this is the cause I have one nested page being loaded, this is a blank page at the moment

View 1 RepliesAsp.net - Bind A Text Box To A Field Selected By SQLDataSource ?
Feb 8, 2011I'm looking for the easiest way to bind data from a SqlDataSource to textboxes dropped in Visual Studio 2008.For example, I have 4 textboxes currently that have Address, City, State, Zip.I also have a SqlDataSource on the page fetching the ID of the record and selecting those 4 fields based on ID. How am I able to quickly bind each box to those particular fields selected? I would think this would be really straight forward - but seems it's not. Seems like the answer is funneled towards having to create a GridView or some type of control.

Bind Data From Text Field On Form To Database Table?
Apr 24, 2011I am trying to bind data from a text box on my form to a field in my database table. First of all I have created a DataSet, BindingSource and Table Adapter in the forms Design view, but I am having from there.

View 2 RepliesLoop Through Child - Bind Textbox To Field Of Parent Table
Mar 22, 2010First I have 2 tables, for example Customer and Orders, and in the database there is a foreign key relation between both. For clarity Orders have a foreign key field to the primary key of Customers, thus Customer is the parent and Orders is the child table of the relation. My application is a Windows Form application, and I add a dataset to the project, in which I drop the 2 tables, and the relations between the 2 tables is automatic added. Now I will om a form loop through the Orders table (witch is the Child table) and show in a textbox some fields of the Orders table and also the Name field of the related record of the customers table. Regarding binding a textbox fo a Orders field I do it this way,
Dim myDs As New DataSet1
Dim myAdpCustomer As New DataSet1TableAdapters.CustomerTableAdapter
Dim myAdpOrders As New DataSet1TableAdapters.OrdersTableAdapter
myAdpCustomer.Fill(myDs.Customers)
myAdpOrders.Fill(myDs.Orders)
Dim myBindingSource As New BindingSource
myBindingSource.DataSource = myDs.Orders
myBindingNavigator.BindingSource = myBindingSource
TextBox1.DataBindings.Add("Text", myBindingSource, myDs.Orders.OrderIDColumn.ColumnName)
But now I can't find how to bind a textbox to a field of the Customers table witch is the Parent table of the relation.

HTML - Encoding A Field Within A Gridview?
Apr 4, 2012I have some of these events in my gridview custom coded. But the real issue here is that I store a previous record, that is, the record that was being changed, or the old.value and I store it in another column. So when the user enters say "< newValue >" without the quotes, the aspx validator rejects the input as dangerous.
I can disable the validation, and html encode the value as it gets written to the db, but when I display the value back in the gridview in the "Previous Value" column it appears like this...< Neutral > semi-colons missing because this site decodes.How I can encode and decode inline in ASPX?How can I encode this template field that is getting entered into a gridview?
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("lang_String") %>'></asp:TextBox>
</EditItemTemplate>
allow certain html characters to be entered into this field only without turning off validation for the entire site.I do need this to apply to the entire column.
