Hi,
I have a button in the ListView ItemTemplate. If th euser clicks the button I need to hide the button and show a value instead.
Here's my code
((Button)lvID.FindControl("btnSearch")).Visible = false;
((Label)lvID.FindControl("lblDynLabel")).Text = getItem;
It gives the following error:
Object reference not set to an instance of an object.

WEll, your code is awful. You should never use FindControl and not check if the return is null.
Unless the getItem is generated on the server side, I'd do this with javascript. Otherwise, I'd use a breakpoint and try to work out what was going wrong. Is lvID the listviewitem ?
Since when does ASP.NET have listviews ?

protected void lvID_ItemDataBound(object sender, ListViewItemEventArgs e)
{
if (e.Item is ListViewDataItem)
{
ListViewItem item = (e.Item as ListViewItem);
Button btn = item.FindControl("btnSearch") as Button;
btn.ForeColor = Color.Red;
}
// if not set AlternatingItemTemplate you have get error.
// must be AlternatingItemTemplate delete or set.

Hi,
I have encountered to an ASP.NET application for first time that forced me to provide some reports in it from data that hosted in a SQL Server 2008, in Visual Studio.NET 2008(Providing data by ADO.NET). Can anyone help me by providing some quick tutorials for me?
Thanks...

Please see following code,
1: Forecolor does not have any effect, the text is always one shallow blue, not red!
2: I want to change the text color with mouseover, but it has no effect!
anyone can give me one hint? What is more, I found that if DisplayMode="Text", the Forecolor has effect!
<style type="text/css"> .lnk { color:Green; } .lnk:hover { color:Aqua; } </style>
<asp:BulletedList ID="BulletedList1" runat="server" ForeColor="Red" DisplayMode="LinkButton" BulletStyle="CustomImage"
BulletImageUrl="~/images/bbb.gif" DataTextField="BookType" DataSourceID="SqlDataSource1" CssClass="lnk"
>
</asp:BulletedList>
thank you!

I am using Visual Studio 2008 and would like to know if I can create a nice glossy, rounded-corner button by deriving from the ASP.NET button class ???
|

I'm sure you can. However, the only way to create the look you want, is to skin your button with bitmaps. I'm not sure you need to extend a class to do that.

I know in previously could see the "hidden" block of code where all the declaration of the event handlers for each event even those of the page load. Where did this code go? Can I still see this code or is it now a black box? C# or VB.

Are you referring to the designer file?
There is no designer file if you have created a "website". A designer file is created only for the web application project.

Hi,
I have an Ajax ModalPopupExtender which contains several textboxes and two buttons, save and close. The problem I am having is that when I use the tab key to move between TextBoxes the ModalPopupExtender loses focus and the focus moves outside of my web page, usually the browser's address bar gets the focus.
Anyone else experienced this? If so, did you manage to solve it and how?
Thanks for your time

I guess you will manually need to set focus on the first textbox in the modal popup. You can do that in the on showing event of the popup through javascript.

Thanks for your reply but I have actually tried that. Even then, when I tab from the first TextBox the browser's address bar gets the focus.
I will check over my code once more see if I have overlooked something. Thanks again for your time

Did you ever find a solution to this ?

|
|
|

yes, although I don't recall what the solution was! I will look when I get to work tomorrow.

I've got SQL Express 2005 and VS 2008 team.
As they specified in Pro ASP.NET 3.5 in C# 2008
1) run aspnet_regsql to generate say ProjMembership db
2) copied it into App_Data from SQLEXPRESS\data folder and attached its path in sseutil -a somepath\ProjMemebership ProjMembership
3) setup web.config as
<connectionStrings>
<add name="MyConnString"
connectionString="Data Source=.\SQLEXPRESS;
Integrated Security=SSPI;initial catalog=ProjMembership"/>
</connectionStrings>
<authentication mode="Forms" />
<membership defaultProvider="MyProvider">
<providers>
<add name="MyProvider"
type="System.Web.Security.SqlMembershipProvider"
connectionStringName="MyConnString"
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="false"
applicationName="/"
requiresUniqueEmail="true"
passwordFormat="Hashed"
maxInvalidPasswordAttempts="3"
minRequiredPasswordLength="5"
minRequiredNonalphanumericCharacters="0"
passwordAttemptWindow="10"
passwordStrengthRegularExpression="" />
</providers>
</membership>
<roleManager enabled="true" />
But when I go to security tab in ASP.NET configuration from VS, it reports:
Cannot open database "ProjMembership" requested by the login. The login failed. Login failed for user 'ACER\user'????

Connectionstring is missing Trusted User=True or say user id and password to login to sql server. Give a try by adding this.

Are we meant to guess what error? Why can't you use it, it's a valid name.
