You don't need to use AJAX, but you do need to use Javascript. AJAX in action is a good AJAX book. What he means is, no matter what, if you're going to use a datagrid, unless you set it up to create hidden rows and use javascript to show them, what you want to do is probably incompatible with using a data bound control. I'd use a repeater, to give you the control you need over the layout so you can set stuff out to be hidden by default and show it via a script.

A bit of background before my problem:
We're doing a security overhaul of our internal applications. We've decided that most pages will have 3 forms of security: read-only, partial input, and full control. The read-only and full controls portions are fairly self-explanatory. The partial input version of the page is controlled by the security roles we setup for the various users. One person may have the ability to edit a particular field, while another doesn't.
We receive complaints about hard to read disabled drop down lists. As of right now we have two solutions: javascript that disables clicking on the control, or a custom control that changes the dropdown to a label when it is disabled.
And now the problem:
I'm working on this second option. I created a class that inherits from the DropDown class and created a new property called ChangeToLabel. Code follows:
<br />
Public Class DropDownDisable<br />
Inherits DropDownList<br />
<br />
Dim lbl As New Label<br />
<br />
Public Property ChangeToLabel() As Boolean<br />
Get<br />
Dim s As Boolean = CBool(ViewState("ChangeToLabel"))<br />
Return s<br />
End Get<br />
Set(ByVal value As Boolean)<br />
<br />
If value = False Then<br />
Me.Visible = True<br />
'Me.Enabled = True<br />
lbl.Visible = False<br />
Else<br />
'lbl.Style.ToString = Me.Style.ToString<br />
lbl.CssClass = Me.CssClass<br />
lbl.Width = Me.Width<br />
lbl.Height = Me.Height<br />
lbl.Visible = True<br />
lbl.Text = MyBase.SelectedItem.Text<br />
lbl.ID = Me.ID & "_disabled"<br />
lbl.BorderColor = Color.FromKnownColor(KnownColor.InactiveBorder)<br />
lbl.CopyBaseAttributes(Me)<br />
lbl.Enabled = True<br />
lbl.TabIndex = -1<br />
Me.Visible = False<br />
Me.Parent.Controls.Add(lbl)<br />
End If<br />
End Set<br />
End Property<br />
<br />
End Class<br />
<br />
The problem occurs when the page containing this control posts back. The newly created labels are getting lost. The even stranger problem is that not every label is disappearing. So far, all of the controls that disappear are in a third-party MultiPage control (we use ComponentArt). We run the security methods on every postback, so I'm assuming the labels are on the page in the appropriate places, and that they're just losing their text values. Thanks for any help you can give me.

Have you tried setting breakpoints to ensure they are created on a postback ? If it only happens in a third party control, have you asked them ? Their control could be doing something that only they can help you with.

Well, my problem was my own dumb fault. As it turned out, I was doing things in the wrong order. I was creating a new label every time the control was built, instead of only creating a new label when the property was called. Now everything works great. Huzzah!!

Is there a way to test to see if the compare validator in JavaScript? My issue is I have a calendar extender and the clientside code calls its corresponding update. The problem lies that if the validator returns true that I don't want to the Update to occurs.
Here's a snippet.
function CalStartChanged()
{
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm._doPostBack('UpdatePanel2','');
}
<asp:UpdatePanel ID="UpdatePanel2" runat="Server">
<ContentTemplate>
<asp:TextBox runat="server" id="txtStartDate" Width="100px" CssClass="LeftSelectionSmall"/> <img src="Images/Calendar.jpg" id="btnStartDate" alt="Choose start date." runat="Server"/>
<ajaxToolkit:CalendarExtender ID="CalendarExtender2" runat="server" TargetControlID="txtStartDate" Animated="False" PopupButtonID="btnStartDate" OnClientDateSelectionChanged="CalStartChanged"/>
</ContentTemplate>
</asp:UpdatePanel>
Protected Sub UpdatePanel2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles UpdatePanel2.Load
If scriptManager1.IsInAsyncPostBack And scriptManager1.AsyncPostBackSourceElementID = "UpdatePanel2" Then
dgresults.DataSource = oData.FillDataTable(StrQueryReturn(txtStartDate.Text, txtEndDate.Text, lstShift.SelectedValue, lstSpecies.SelectedValue, lstPackType.SelectedValue))
dgresults.DataBind()
'Put the sql in the cheat box
CB.Text = StrQueryReturn(txtStartDate.Text, txtEndDate.Text, lstShift.SelectedValue, lstSpecies.SelectedValue, lstPackType.SelectedValue)
End If
End Sub

Hi
After 3 years of bodging our reporting requirements with anything and everything from HTML browser based reports to Tall PDF based reports, and a brief flirtation with ComponentOne's reporting engine we have now decided to attempt to solve this issue once and for all LOL!!!
Anyway we have some very complex reports, some include charts intermingled with tabular data, some require the titles to be displayed vertically etc. and then more simple mail merge type requirements so a good varied range of reporting styles and layouts.
So what are peoples opinions, what are peoples experiences of different tools, anybody used Crystal Reports??
Suggestions please, all help greatly appreciated it looks like a mine field out there everybody claims the earth but little has delivered to date!
Thanks in advance
Andy

I used to use SQL reporting Service in ASP.NET project..
|
|
|
|
|
Is this SQL 2005 specific?
|
|
|
|
|
Nope.. It can be used with SQL 2000..
|
|
|
|
|
thanks for your feedback Michael much appreciated 
can I build reports in the SQL 2005 environmentand then migrate them to SQL 2000, do you know?
does SQL EXPRESS 2005 support trport services?
thanks in advance
Andy

A point of clarification should be made regarding the relationship between SQL Server and SSRS. Reports developed using SSRS can link to a variety of data sources. These include SQL Server, Oracle, any ODBC-compliant data source and XML. This means that the data for your reports doesn't need to be stored in SQL Server. However SSRS requires an instance of SQL Server to be installed as it stores the metadata for its report catalog in a SQL Server database. This can be either SQL 2000 or SQL 2005.

I have been looking through an ASP .NET project that is written in VB .NET. I was wondering what #If was and also if that's any different than just an if statement. Could someone please explain? I have been unable to find any information on it.

I think this is something that is used in C/C++ world. (but of course, it can be used in C# too.)
Check-out the link below for more details..
#if[^]
I never use this in my project so I don't have that much idea about that..
As this article " Conditional Attribute in C# compared to #if #endif[^]" said, conditional attribute might be more readable than #if.
Hope it helps.

Those are pre-processor directives. It begins with a # symbol. Preprocessor directives are handled by compiler.

i have a drop down list inside a gridview,i need to get the selecteditem.value of the selected item ,but i am getting only the value for the first item only,even if i select any other item..
heres the code i used plz help me...
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow selectedRow = ((GridView)e.CommandSource).Rows[index];
string value = selectedRow.Cells[0].Text;
DropDownList ddl = (DropDownList)selectedRow.Cells[5].FindControl("ddlVendorName");
string mystr = ddl.SelectedItem.value;

mithun narayanan wrote: GridViewRow selectedRow = ((GridView)e.CommandSource).Rows[index];
I think this code might be wrong. As you are getting only one selected row, you won't get the list of rows that you want. So, maybe. You should try to for-loop all rows and get the value..

Set LinkButton.CommandArgument = _bbMembers.MemberID.ToString()
in the GridView_RowDataBound function and fetch this memberID in the RowCommand Event like
dim memberID as string = e.CommandArgument
Now call the Protected Sub FillMemberDetails(memberID) function in the RowCommand event.
Hope this works for you!!
