Assume that you load a table into the datagrid. It has some column like id, name, address etc. You add a checkbox into the datagrid using grid template. So if you want to fill / get bool value you need to do something like:
foreach (GridViewRow row in datagridView.Rows)
{
CheckBox cbYesOrNo = (CheckBox)row.FindControl("cbYesNo");
if (cbYesOrNo.Checked)
{
}
else
{
}
}

Experts,
I have a web browser in vb.net, works like a treat
However is there any way that on a button click in the html web page through vb.net, can i then have a button that is invisible in vb.net to be then be visible to the user on the vb page.
e.g the web page is shown but the user doesn't do any thing. - nothing happens
the user types something in - nothing happens on the vb side
the user types something in a presses the submit buttons - a vb button appears allowing them to continue.
Any ideas?

Hi,
you could;
1. modify the web page any way you like, it is available as WebBrowser.DocumentText
2. add JavaScript (assuming JS is enabled).
3. add/modify hyperlinks, possibly pointing to your own web site
4. provide an embedded HTTP server, which means your own web site could be embedded inside your app (see e.g. Sample HTTP Server Skeleton in C#[^])

It sounds like you have a WebBrowser component displaying some HTML embedded in a windows Form, and you want to respond to events that cause a postback in the web page in the windows form. I am assuming that is what you are getting at.
We have a similar thing where html is used to display details inside a windows form and hyperlinks cause a new windows form to pop up instead of navigating in the HTML.
We do this by handling the BeforeNavigate event of the browser and interrogating the URL requested. If the URL requires custom navigation in the windows application then we set e.Cancel = True to stop the default navigation continuing and instead run our own custom code.
It is all a bit messy, but that is the price for a hybrid windows/web solution.

Is there a way to 'walk' the Document Outline tree and iterate through each control/object displayed? I am working on an in-house project for applying default settings to various controls on a form.
I've tried doing a recursive loop through Me.Controls, identifying if the control as children, and so forth. The problem is that we are using a mixture of standard VB control as well as third-party control (DevExpress, ComponentOne, etc) and the third-party controls are not always a part of the Me.Controls collection. However, they do appear when viewing the Document Outline tree for a given form. So I got the idea to see if I could walk the Document Outline, identify the various controls, and apply settings that way. Of course, I've found no way to walk the Document Outline.
If there's a better way to do this, I'm open to suggestion. Otherwise, I'd appreciate any help or direction that someone could offer. Thanks!

If you're talking about an ASP.NET webform, move this question to the ASP.NET forum.
If you're talking about a Windows Forms form, there's no such Document Outline concept and you'll have to further explain what you're talking about.

I'm talking about a Windows Forms project in Visual Basic 2005.
To see the Document Outline panel, open a form in your project, and click on View ->Other Windows -> Document Outline. The keyboard shortcut is Ctrl+Alt+T.
What I want to do is iterate through the objects represented in the Document Outline. Because some objects aren't available through the Me.Controls collection, I need another method to iterate through them. The Document Outline shows all objects, even those that are not available in the Me.Controls collections. I am hoping there is a way to iterate through that tree structure to reference the objects.
Thanks again in advance for any assistance.

OK. The Document Outline you're talking about is the Controls collection of the Form being designed, and every Controls collection of every control in it.
There is no seperate DOM for Windows Forms other than the Controls collection.

Can we use the text of a textbox as a query filter in VB? If yes how?
|
|
|
|
|
Yes you want to have a look at the dataview class.
assuming you have data loaded into a datatable, this example i use from the changing of the date in a datetimepicker
dim dv as dataview
dv = new dataview(dt)
Private Sub DateTimePicker1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged
' MessageBox.Show(DateTimePicker1.Text)
dv.RowFilter = "duedate = '" & DateTimePicker1.Text & "'"
End Sub

I wanted to ask this way.
I have a query for my data grid view as:
SELECT ID, Name, City, Fee, Technology
FROM [uni list]
WHERE (Name = 'Data')
where data is used as a string and this works fine BUT..
When i refer the filter case to a textbox it doesn't work. It takes this whole thing as a string and not producing the desired results.
SELECT ID, Name, City, Fee, Technology
FROM [uni list]
WHERE (Name = '[text].textbox1')
How can this be resolves

how do you get your data to the grid? is it via a dataset or datatable?
if datatable then
this bit goes in the event that loads your grid
dim myDataView as new dataview(myDataTable)
Datagridview1.datasource = myDataview
if Dataset then
dim myDataview as new dataview(myDataset.tables(0))
Datagridview1.datasource = myDataview
but the filtering is the same how ever
this bit goes in what you use to fire the filtering, i prefer to use a button to allow filetering
myDataView.Filter = "[Name] = '" & yourTextBox.text & "'"
if you need more help i would need to see your vb.net code as that is where its done and not at the sql statement.

Hi Guys!
I am in a bit of a Dilemma here again. As much as office 2007 has provided more options in Excel, it has made it darn difficult to do things which were so easy until Office 2003.
The problem is, I want to create macros which change the background color of the selected cells according to the company colors. There are 6 different colors which need to be applied. I did the record macro option which works fine and places icons next to the save button on the top left corner in Excel 2007. But my boss wants something different, he want a seperate ribbon with the different color options and also that it should be an add-in otherwise it would be hard to implement all these macros on more than 600 computers world-wide. Can anyone please help me out with this one. I have no experience with VB.Net or Microsoft Office programming. I am a web developer but this is something that has been haunting me for a few days now.
To wrap it up, I need to make an Add-In for Microsoft Office 2007 which sits in its own ribbon and has 6 different options. All these options change the background colors respectively, of the selected cells in Excel and needs to be easy to implement by the staff world-wide, we can just provide them with the add-on to run on their computers. Also, this would need to cater for the existing files as well which takes the template files out of the question unless there is a way to make the template file as the default sheet that opens up the existing data.
Any help, suggestions, examples or references will be highly appreciated.
Thanks.

Sounds like your boss needs to be put in charge of paper clips or something mildly clerical.

Hey mate!
Thanks for that. An amazing article and very user friendly. But now I am stuck on the part where I need to call the function to make the color change. I tried to copy the code from the macro but that keeps giving me weird errors like MissingMemberException: Public member 'Selection' on Type 'RibbonButton' not found etc
Any reference on this would be great. I am googling myself as well but would like to thank in advance.
regards.

You're welcome.
Unfortunately I have not had to do any projects like this myself, so I haven't tried the code or anything.
Your best bet might be to send the author of the article a message.
My advice is free, and you may get what you paid for.

Hi there, I'm newbie here,
I want to know, to set default value for property, which is the best way?
1.
Private _AddFoto As Boolean = False
Public Property AddFoto() As Boolean
Get
Return _AddFoto
End Get
Set(ByVal value As Boolean)
_AddFoto = value
End Set
End Property
Or
2.
Private _AddFoto As Boolean
<ComponentModel.DefaultValue(False)> _
Public Property AddFoto() As Boolean
Get
Return _AddFoto
End Get
Set(ByVal value As Boolean)
_AddFoto = value
End Set
End Property
Thanks

I always use the first case. Does case 2 work? I tried your sample by setting
<Componentmodel.Defaultvalue(True)>... but this doesn't seem to work.
