VS is just an editor. It has nothing to do with RadioButtonList.

Thanks for reviewing my question. I hope this is the right forum.
I am trying create a sqldatasource, menu control, grid view controll, and ajax update panel which will be added dynamically during runtime in a for loop. the code below works except that I must click on the menu item twice to get it to requery the database and update the gridview. Any suggestions why this is. i am using visual studio 2008.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Dim up1 As UpdatePanel = New UpdatePanel()
up1.ID = "up1"

'--Menu---

Dim menu3 As New Menu()
Menu3.ID = "menu3"
Dim i As Integer
For i = 2005 To 2009
Dim mItem As New MenuItem(i.ToString, i.ToString)
menu3.Items.Add(mItem)
Next
menu3.Orientation = Orientation.Horizontal
menu3.StaticMenuItemStyle.HorizontalPadding = 5
up1.ContentTemplateContainer.Controls.Add(menu3)

'---DataSource----

Dim ds As SqlDataSource = New SqlDataSource()
ds.ConnectionString = "my connection string"
ds.SelectCommand = "SELECT * FROM table WHERE filedate > @filedate"

'--ControlParemeter-----

Dim cp As ControlParameter = New ControlParameter()
cp.ControlID = "menu3"
cp.Name = "filedate"
cp.PropertyName = "SelectedValue"
cp.DefaultValue = "12/31/2008"
ds.SelectParameters.Clear()
ds.SelectParameters.Add(cp)
up1.ContentTemplateContainer.Controls.Add(ds)

'--GridView --

Dim gridview3 As New GridView()
gridview3.DataSource = ds

'---Add controls to update panel and add update panel to site---

up1.ContentTemplateContainer.Controls.Add(gridview3)
pnl1.Controls.Add(up1)

'---Bind Datasource to gridview---.

gridview3.DataBind()

end sub

So if it works what is your problem? You want to know how to break it?

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

Thanks for your reply, I should have been more specicific in the subject but was woried it was getting to long. The code will generate the menu grid and datasource but i have to click on the menu item twice before it will update the grid.

I think it is because your code is firing on every postback in the page_load.

You should use
if not ispostback
begin

end

Then put the databind code in the onclick event of the menu.

Thanks for the reply I am going to try this but I must first find out how to link and event to a dynamically created control. i believe I can use the AddHandler like below.

AddHandler Menu3.MenuItemClick, AddressOf Menu3_Click

Public sub Menu3_Click(ByVal sender as system.object,ByVal e as System.EventArgs)
'Databind code
End Sub

but it does not seem to be working. I will do some research and once I have this working I will let you know if moving this code from the page load fixes the original problem.

Thanks again.

Good luck. If you have never been here, you might want to read this brief article about the ASP.Net Page Lifecycle. It will probably help you to understand things a bit better. http://www.codeasp.net/articles/asp.net/20/aspnet-page-lifecycle[^]

Hi Dear
I use VS 2005, in Gridview i have a column that in the Basic Table have a relationship to other Table. I want like a combobox, show another field to the user, not show the forign key.
How can i do that?

Hi,
Explain your problem in detail. As no one can make out what your problem is. Your foreign key issue you should handle from sql query.

I guess your solution is the "DataKeyNames" property of gridview.

Re: Gridview Number Format

I think DataFormatString="{0:###,###,###}" will work.

DataFormatString="{0:#,#}" is enough to make the trick hapen.

In Word you can only store 2 bytes. That is why I use Writer.

So far so good

Abhishek Rana wrote:

If all you want to do is handle the select changed event in javascript, why do you need updatepanel? Update panel is used/needed only if you have to process the event on the server, so you don't refresh the whole page.

Abhishek Rana wrote:

No there is no way you can access the variables from javascript.

Abhishek Rana wrote:

Yes, Since you have update panel, forget about javascript and handle what ever you want on the server. Things will work for you magically.

Funny.

But I agree with Yusuf. Unless you are writing a website that will be very high volume, it is always easist and cleanest to just write your code in C# and use the ajax panel. It is one thing if you are proficient with asp.net, html, javascirpt and it easy for you. But if you are not an expert, don't even bother trying to use a bunch of javascript. You will probably just shoot yourself in the foot.

Hi Dear
I registered as ASPSpider.com member. I uploaded my Database and ASP.NET 2005 files in my space, but when i connected to the address http://aspspider.info/sasannaderi/ (you can see it online) this error occured :
Keyword not supported: 'integrated security'.

My connectionStrings is this :

</connectionStrings>

Can anyone help me to solve the problem?

Integrated Security=SSPI means using Windows Authentication. Does that give you a clue?

Windows authetication works well in local environment. But not in deployed environment. Thats whay you are getting this problem. You have to use Sql Server authentication with proper userid and password.

Thanks,
