There is no implementation for the message box in asp.net like vb.net desktop application
instead u need to use the "window.open" for opening a new window
"window.alert" for messages and "window.confirm" for checking yes/no messges
Hope this would help
Best Regards

msgbox("Error occurs",MsgBoxStyle.Information,"Title")

You can't use a MessageBox in ASP.NET, as that would show up on the server, and the server side of a web application does not have a user interface. Use a Javascript alert:
window.alert('The message.');
---
b { font-weight: normal; }
|
|
|
|
|
You can not do this in asp.net.
You have to use Javascript to do display an alert message.
and the function is->Alert("Message")

Hi,
In my website, I need to give a popdown menu to the user for various options.
Suppose, the menu options ar as follows :-
Home View Records Reports Exit
1 - Batch 3 - Error
2 - Summary 4 - Valid
5 - Dropped
Where Home and Exit are independent links with no sub menus whereas View Records has sub menu 1 & 2 and Reports has sub menu 3,4 & 5
How do I create this using the new ASP.NET 2.0 menu control. I also need to implement role based security in this. For eg. if a particular menu item is not accessible to a particular role, then either that menu item should be disabled or preferably not rendered at all.
I will be using this control for the 1st time, so pls guide me in how to proceed.
Thanks and best regards

Dear ALL,
I am facing a bit problem in DATAGRID. so may be you guys can help me
out.
Actually on a DataGrid I am having following controls:
1) 2 DropDown Menu
2) 1 Text Box
3) 1 ADD Button
4) 1 Remove Button
So these all controls are in 1 row and looks like:
DROPDOWN1 DROPDOWN2 TEXTBOX ADD BUTTON REMOVE BUTTON.
So when user will press ADD Button then the same new row will be
populated and will look like.
DROPDOWN1 DROPDOWN2 TEXTBOX ADD BUTTON REMOVE BUTTON (ROW1)
DROPDOWN1 DROPDOWN2 TEXTBOX ADD BUTTON REMOVE BUTTON (ROW2)
And So on. So these rows will be populated until user press ADD BUTTON.
and similarly on pressing the REMOVE BUTTON the corresponding ROW will
be deleted.
I have implemented this functionality. but NOW the REAL PROBLEM comes
into picture.
Actually, when this SECOND ROW (ROW 2 and so on) will be populated
then I have to set the VISIBILITY of ADD BUTTON of FIRST ROW (or
previous row) to FALSE.
SO LOGICALLY SPEAKING this ADD Button should be visible only for the
CURRENT ROW and for all the previous rows the ADD BUTTON's TEXT should
be replaced by a LABEL Control.
I tried to access this BUTTON CONTROL a lot but was unable to do that.
So if you have any idea then please let me know. I am posting the code
for your review. Your help is really appreciated.
public void Page_Load(object sender, System.EventArgs e)
{
if (!IsPostBack)
{
dsSource.Tables.Add(new DataTable("RepeaterSource"));
dsSource.Tables[0].Columns.Add(new DataColumn("DropDownValue2"));
dsSource.Tables[0].Columns.Add(new DataColumn("EditBoxValue"));
dsSource.Tables[0].Rows.Add(new Object[] { 2,""});
datagrid1.DataSource = dsSource;
datagrid1.DataMember = "RepeaterSource";
datagrid1.DataBind();
Session[DATA_SOURCE_KEY] = dsSource;
}
else
{
dsSource = (DataSet)Session[DATA_SOURCE_KEY];
datagrid1.DataSource = dsSource;
datagrid1.DataMember = "RepeaterSource";
}
}
public void OnItemCommand(Object sender, DataGridCommandEventArgs e)
{
if(e.CommandName == "Add")
dsSource.Tables[0].Rows.Add(new object[] {1,"Text Here" });
datagrid1.DataBind();
Session[DATA_SOURCE_KEY] = dsSource;
}
if(e.CommandName =="Delete")
{
dsSource.Tables[0].Rows[e.Item.ItemIndex].Delete();
datagrid1.DataBind();
Session[DATA_SOURCE_KEY] = dsSource;
}
}
HERE IS THE CODE BEHIND PAGE:`
<asp:datagrid id="datagrid1" runat="server" width="288px"

Hello,
I am completely confused in relation to Themes and CssClass in Asp.Net 2.0.
Consider a custom control (MyControl) that I am creating which composed by:
Panel_01
Table_01
Label_01
Image_01
Hyperlink_01
Panel_02
Label_02
Now, consider I want the text in Label_01 to be different of text in Label_02.
And that I want to format the <a> tags in Hyperlink_01 as follows:
.a, .a:link, .a:visited {color: #950C00; text-decoration: underline;}
.a:hover, .a:active {color: #950C00;text-decoration: none;}
How should I set the SkinIDs and CssClasses in my controls inside my Custom control so I can make this work.
I am asking this because sometimes using Skins seems to be a limit over CSS.
Sometimes I end up using many Skins...
Could someone give me some advice on this?
Thanks,
Miguel

when i load the app configuration page from the solution explorer im presented with the page that allows you to add app settings, set up security etc..
all very nice, however whenever i click security it tells me that i havent specified a data store and then when i click the 'choose data store' button it takes me to the provider page where im given a 'test' link which then tells me that it couldnt connect to the database.
I know that i need a connection string to the database that i have run aspnet_regsql.exe upon - but why cant i configure this through those pages????
i have to manually add the code into the web.config (which i found on an msdn page).
surely i must be missing a configurastion step here?

Hello,
I have a custom control where I have a button.
I need to raise the event FormSubmited after all the code, in
Button_Click, is finished.
The problem is when I check FormSubmited in my page nothing happens:
Private Sub Form_FormSubmited(ByVal sender As Object, ByVal e As
EventArgs) Handles Form.FormSubmited
Response.Write("For Was Submited")
End Sub
My custom control code is as follows:
...
Public Class Contact
Inherits WebControl
Private Sub bSubmit_Init(ByVal sender As Object, ByVal e As
System.EventArgs)
.....
End Sub
Private Sub bSubmit_Click(ByVal sender As Object, ByVal e As
System.EventArgs)
' SOME CODE
' Raise the OnFormSubmited event
RaiseEvent FormSubmited(Me, EventArgs.Empty)
End Sub
Public Event FormSubmited As EventHandler
Protected Overridable Sub OnFormSubmited(ByVal e As EventArgs)
RaiseEvent FormSubmited(Me, e)
End Sub
Protected Overrides Sub CreateChildControls()
AddHandler bSubmit.Init, AddressOf bSubmit_Init
AddHandler bSubmit.Click, AddressOf bSubmit_Click
MyBase.Controls.Add(bSubmit)
End Sub
End Class
Could someone tell me what am I doing wrong here?
Thanks,
Miguel
