Asp.net - Bind Check On Column?
Jul 15, 2011
But I'm having a problem with showing the right info in a gridview.
Basically I've got a maintenance tool for an application. And I want to make it multi language.
This is a check for the language:
'setting the column name where to get the text resource from
Dim comment As String = "comment"
If (licentie.getlanguage() = "NL") Then
[Code]....
So far this works. But in my template I've got the following code in the gridview:
<asp:Label ID="LabelType" runat="server" Text='<%# Bind("Comment") %>' />
How do I set the column 'comment_NL' when the language is set 'NL' in the bind?

I'm trying to do the following for asp.net combobox:
Text='<%# IIf(Eval("Name").ToString().Equals(""), Bind("Other"), Bind("Name") %>'
What I'm trying to do is if the "Name" column is empty then bind to "Other" column, otherwise bind to "Name" column.

I'm trying to display the serial number of the 'recipient' you selected in a textbox but I get this error:
System.ArgumentException: Cannot bind to the property or column RecipientSNo on the DataSource.
I did this to another textbox with a different query (same codes, just changed the column name from 'recipient' to 'issuer') just to debug and it works! I tried it again to the 'recipient' but it still doesn;t work.My code:
query("SELECT RecipientSNo FROM Recipient WHERE CONCAT(FirstName, ' ', MI, '. ', LastName) = '" & ReceiverName.Text & "';")
Try
adapter = New MySqlDataAdapter(CommandText, ServerString)
table = New DataTable
[code]....
I just coped this code and changed the textbox and column names and it did not work already.. What seems to be the problem? I double checked my table and column names already.

I have a Datagridview with a bound datatable in it. Then I add a check box column to it.
When I click the headder of the DGV, it sorts the bound columns, and clears all checked checkboxes in the checkbox column.
How do I bind the checkboxcolumn to the rest of the table?

it's possibly to bind the values in a combobox to a column in a dataset? If so, how would I go about doing it? For example, If I have a column named 'Names' in a DataSet, each comboBox item would be a name from that column.(There will only me at maximum, 10 entries)

I have the following code on a form:
Public Sub Init(ByVal SelectedItems As List(Of Cheque))
Items = New BindingList(Of Cheque)(SelectedItems )
BindingSource1.DataSource = Items
[code]....
This code gets called like so:
...
fmEdit.Init(myList)
fmEdit.Show()
All variables are populated etc, it seems to go through the DataBindings.Add ok but when the form appears I get the error about unable to bind to a property or column called Id. I tried replacing the DataBindings.Add code to use the BindingSource1 instead of Items but I get a similar error.The names of the properties in the class match that of the name in the Databindings.Add code.
UPDATE: Here is my class:
Public Class Cheque
Public Id As String
Public Status As Byte
[code]....

I would like to bind different queries for a long set of columns in datagridview that has been set already during the formload, e.g:
With dgvGrid
.Columns(0).Name = "Dept Code"
.Columns(1).Name = "Emp ID"[code]....
there are still more of it. The data needed for those columns is coming from a different table.

When I try to use the following line of code:
cboSite.DataBindings.Add("Text", _dtSite.Select("Site <> 'ALL'"), "Site")
I get the following exception:
EXCEPTION : Cannot bind to the property or column Site on the DataSource.{10}Parameter name: dataMember
details I am connecting to an Access database and using .net 3.5 and writing the code in VB. In this database I have a table named Sites with a column named Site and when I try to use the line of code above I get the exception noted. I was under the impression that I could explicitly name the column that I need to use in my control (combo box).
