Events not firing after adding a particular User control in ASP.NET 2005

Hi,
I am a newbie and developing a web application in ASP.NET 2005. In one of my page I am having three different Usercontrols. However when I run my page in FF everything seems fine even after postback. But in IE after Pageload when i click buttons or even change options from Dropdown nothing appears to happen.(My dropdown is having event "SelecetedIndexChanged" and Autopostback is also set as true). Although the page postbacks, but rather to go in any event handlers (except Page_Load) it directly jumps to usercontrols.cs file after checking postback property and leaves from there right only rather to continue with specific eventhandlers. I tried by removing one of my user controls and everything works fine. I don't know how to solve this problem. I have also used EventValidation="false" in Page property section but of no use.

Just surprised to see FF is working fine with the same user controls and I even dont have any particular settings for my IE browser.
I modified, developed a new Usercontrol but alas of no use.

My Usercontrols HTML code is satisfying all W3c norms and nothing seems wrong in it (I hope so) and attached here.

Need Immediate Help,
Any Replies appreciated.
Thanks,

Your HTML Code that you pasted doesn't show properly in your post. What about making small sample ASP.NET project that works fine in FF and not in IE and show to us?

We will download and try to reproduce your error at our site. then, will let u know the result.. what do you say? Smile | :)

Why is VS creating 2 project folders?

I am trying to make a start on creating a website (something I don't have a huge amount of experience with). I choose the asp.net website template and the solution is created and loaded for me. The problem is that when I go to look in the solution folder I find 2 folders, Website1 and Website1(2). Website1 contains the code files, Website1(2) contains the solution files.
Can someone please tell me why this is behaving like this?

Thanks.

As default, Visual Studio used to create two folders for website.

1. WebSite Code : %userprofile%\Documents\Visual Studio 2005\WebSites\MyWebSite

2. Solution file : %userprofile%\Documents\Visual Studio 2005\Projects\MyWebSite

Normally, the name of folder under Projects and the folder name under Websites will be the same. but I think the reason why the name (WebSite1 and Website1(2)) are different in your case is that there might be one folder called Website1 already exists in that path so that the name automatically changed from Website1 to Website1(2).

Hope it helps.

CheckBoxField

I have a GridView which has a non data bound CheckBoxField:

<asp:templatefield headertext="Sel">
<itemtemplate>
<asp:checkbox runat="server" id="SelectCheckBox">

The user can check or uncheck data rows (done on the client side). The user can then perform various functions (print, view, e-mail etc.) on the checked rows. Since these functions are activated by Buttons, I can read and save the checked status of each row within the function call code. Upon return from the function, I set the checked status to where it was (I restore the status in the GridView_OnRowDataBound call). This works fine.

However, each data row also has a separate HyperLinkField. The problem I have is when the HyperLink is clicked, I can't read the checked status of the rows so that I can later restore them. It looks like the GridView is destroyed prior to the HyperLink transfer.

Any suggestions?

What error you are getting ? ASP.NET treats APP_CODE as a single assembly. Post sample code where you are getting error.

Problems selecting records

Hi,

I'm having a problem selecting records from my database to display on the web page. I want to select all records with a specific name, and on a specific date. The code I'm using looks like this:

<br />
StrConnect = Server.MapPath("./MyDataBase.mdb")<br />
cn = Server.CreateObject("ADODB.Connection")<br />
cn.Open("PROVIDER=MICROSOFT.JET.OLEDB.4.0;Data Source =" & StrConnect)<br />
rs = Server.CreateObject("ADODB.Recordset")<br />
rs.Open("SELECT * FROM TheLog WHERE name='123' AND recdate=#01/02/2003#", cn, 3)<br />

Now despite there being about 5 records with that name and date, I don't get any records returned.

Does anyone know why?

P.S. The database is a Access database, the name field is set to "Text" and the recdate field is set to "Date/Time"

Try using a range of dates (eg. between 01/02/2003 00:00:00 and 01/02/2003 23:59:59, don't use my syntax ) rather than specifying recdate to be exactly equal to 01/02/2003

Nope, didn't work.

:/

The string I used was:
SELECT * FROM TheLog WHERE name='123' AND recdate BETWEEN #01/02/2003 00:00:00# AND #01/02/2003 23:59:59#

Also,just to note, when I ouput the date field to a text box, I get:
01/02/2003

and you try this

Name is reserved? Bah.

Well I've changed the field to Job now. and I've tried both:
"SELECT * FROM TheLog WHERE job='123' AND recdate=#01/02/2003#"
And
"SELECT * FROM TheLog WHERE [job]='123' AND recdate=#01/02/2003#"

Neither of them work.

This does work however:
"SELECT * FROM TheLog WHERE job='123'"

Assigning a BackColor in code

Hi,

This may be a stupid question, but I'm having troubles assigning a hex value to the backcolor of a table cell with code.
I'm currently adding values into a table with code, but I would like to change the back color by giving the color's hex code or #code.
In the visual designer I can easily add the hex code, why not with code or am I forced to split it into blue, red and green or just use the basic system.drawing.color choices?

Hope someone can help Smile | :)

Kind regards

You create a Color value using the FromArgb method:

SomeTableCell.BackColor = Color.FromArgb(0xffff00); // yellow

or

SomeTableCell.BackColor = Color.FromArgb(0x80, 0x80, 0x80); // grey

Inserting a property value into the meta tag

Hi all,

I'm loading the meta tag values form the database for the description and the keywords, but its not doing what I want it to.

Currently I have the following

<meta name="keywords" content="<%=Keywords %>" />

Keywords being a property in codebehind, but if I view the source of the page when I run it, it displays the content of the tag as follows & lt%=Keywords %& lt

No matter how long he who laughs last laughs, he who laughs first has a head start!

You can use the headers property of the page to add information to meta tags, for example

Dim meta as new HtmlMeta()
meta.Keywords = "test, stuff"

Header.Controls.Add(meta)

Try taking a look at that and if you get any problems post back

Thanks for the reply, What I did was added the runat attr to the meta tag, and then in the code behind I just used metaId.Content and assign the property to that

You can try it using a method that returns the keyword.

<meta name="keywords" content="<%=GetKeywords() %>">

public string GetKey()
{
return keywords;
}

Problem with TreeView selected node!

Hi there,

I've got a TreeView like below
1
1.1
1.2
1.2.1
1.2.2
1.2.3
1.3
2

The code in SelectedIndexChange event like below

TreeNode currentNode = TreeView1.SelectedNode;<br />
        TreeNode parentNode = currentNode.Parent;<br />
<br />
        currentNode.Select();<br />
        <br />
        if (parentNode != null)<br />
        {<br />
            Response.Write(parentNode.ChildNodes.IndexOf(currentNode));<br />
        }<br />
        else<br />
            Response.Write(TreeView1.Nodes.IndexOf(currentNode));

If I clicked 1.2.1 or 1.2.2. or 1.2.3, the page would say the index of the node I've cliked right.
If I clicked 1 or 1.1 or 1.2 or 1.3 or 2, the page would say the index of the node I've clicked is 0. WTF | :WTF:

I don't know why, the index of 2 should be 1, index of 1.3 should be 2, ... but it wasn't correctly.

Anyone help me solve this issue.

Thanks.

i was busy with selecting fw version on iss, some buddies said, there is a ASPNET tab on properties at context menu of default web site, but i couldnt see, at the end, i see "web server extensions" then i prohibit fw v1.1, so i never get "couldnt fint the path....bla bla bla" error message.

and now, i get this messge "Page cannot be displayed". i searched then saw
You receive a "Page cannot be displayed" error message when you use an ASP.NET application to open an .htm file or another static file that is hosted in IIS 6.0[^]

But the problem is that i dont have "static files" all of them is aspx and dynamic pages.

How can i fix ?

I think you are looking for the documents tab in the IIS manager. This is where you set the start page of your site. It usually defaults to default.htm. So whatever you want your start page to be, you need to add it and put it at the top of the documents.

Hope that helps.

I am using datatable in my application to show the data in gridview.Now what I want is that when user enter a new line application should check the datatable.if the record exists then it should show a warning otherwise add a new row in datatable.

I am using the following code to check the datatable through loop.

Dim x As DataRow

For Each x In mydatatable.Rows
If x.Item(1).ToString = Me.TextBox1.Text Then
Me.Label1.Text = "Exist"
End If
Next

With the above code I am getting error 'Object reference not set to an instance of an object.' at the first row of the for loop

Wow - TextBox1 and Label1 are variables in production code ? That's pretty grim.

Please don't crosspost. Where you asked in the VB.NET forum is probably the best place for this, as it doesn't directly involve ASP.NET.

Obviously you have a Row which doesn't have 2 items in it. It's always good practice to test your assumptions, as in

if x.Items.Count > 1 && x.Item(1).ToString = Me.TextBox1.Text Then

something like that.
