I want to use the 'AddAt' method with a dynamically generated repeater. It doesn't work. It's just like the whole repeater has only one item because i only can add an item 'before' or 'after' the whole repeater.
I use this ItemTemplate class
Public Class clsNavigatieDetail1ItemTemplate
Implements ITemplate
Private mboOpgevuld As Boolean
Private moRepeater As Repeater
Private msNavigatieDetail1 As String
Public Sub InstantiateIn(ByVal container As System.Web.UI.Control) Implements System.Web.UI.ITemplate.InstantiateIn
Try
If Not mboOpgevuld Then
mboOpgevuld = True
Dim oDataTable As DataTable
oDataTable = CType(moRepeater.DataSource, DataTable)
For i As Integer = 0 To oDataTable.Rows.Count - 1
Dim sItem As String
sItem = "<div class='NavigatieMenuDetail1'>"
sItem += "<div class='divMenuCell3' class='NavigatieMenuDetail1'> </div>"
sItem += "<div class='divMenuCell4'>"
sItem += "<a href='javascript:doPostback();setNavigatieDetail1 (" + oDataTable.Rows(i)("IDSubNavigatie1").ToString + ");'>"
sItem += oDataTable.Rows(i)("OmschrijvingSubNavigatie")
sItem += "</a>"
sItem += "</div></div>"
Dim oLiteralControl As New LiteralControl
oLiteralControl.Text = sItem
container.Controls.Add(oLiteralControl)
Next
End If
Catch
End Try
End Sub
Public Sub New(ByVal oRepeater As Repeater, ByVal sNavigatieDetail1 As String)
mboOpgevuld = False
moRepeater = oRepeater
msNavigatieDetail1 = sNavigatieDetail1
End Sub
End Class

Hello all!
I am new to writing custom controls and have an issue with text box fields not persisting their values on post back. Here is an example of a class I wrote to demostrate my problem, I set the value of the textbox using javascript, however on postback the value disappears. How do I get around this?
Thanks in advance.

btn.Text = "Assign";<br />
btn.Attributes.Add("onclick", "document.getElementById('" + txtBox.ClientID + "').value = 'my value'; alert('Value Set!');");<br />

Because there's no code to move the text to your viewstate variable. Just get/set the text property of the textbox, and let the textboxes ViewState handle the rest.

ok, I am a noob at this! 
something like this?
public string TextBoxText<br />
{<br />
get<br />
{<br />
return txtBox.Text;<br />
}<br />
<br />
set<br />
{<br />
txtBox.Text = value;<br />
}<br />
}

Yes, that's just what I meant. If the textbox doesn't have viewstate disabled, it will keep the text all by itself.

tried it, after clicking the button on post back the textbox value is blank again. Does this not have anything to do with the control being dynamically created again?
|

Oh - you're dynamically creating the control ? Why didn't you just add it to the ascx for your control ?
If you're creating the textbox in code, then it needs to exist prior to page load, or viewstate won't work, i.e. it won't be possible by any means to get the text that was entered.

Hi all,
In the master page i need to read a value from the web.config file (key="PathLogout"). To read PathLogout i have placed a hiiden label <asp:Label ID="Label1" runat="server" style="display:none" Text="<%$ AppSettings:FreeAndClose %>"></asp:Label>
Inisde a javscript function i am reading it as follows:
var myVar = document.getElementById('<%= Label1.ClientID %>').innerHTML;
alert(myVar);
an error is generated "The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)."
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Any ideas why and how can i solve it.

I think you want =, not $. The syntax with the colon looks wrong, too ?
One way to solve it, is to set the value of the textbox in your code behind. A more sensible way would be to write something like
var MyVar = '<%=AppSettings:whatevert%>';
and leave your textbox out of it

I am not sure where this AppSettings: format is coming from. Your best bet IMO is to reference a codebehind variable in your ASPX and in your code behind, write code that really DOES read your app settings.

This is my appsettings from web.config
<appSettings>
<add key="EncKey" value="%P[,#$x/#@?,:*"></add>
<add key="PathLogout" value="http://10.1.5.29/CID/Logout.aspx"></add> </appSettings>
also in the code behind of the master page i have added
Imports System.Configuration.ConfigurationSettings

iam not sure of what u have said

ConfigurationManager.ConnectionStrings("KeyName")
if i do so how can i read it in the javascript, u mean to load it to hidden variable.
thanks again for ur help

What I'm saying is, have the code in the aspx that creates the javascript variable access a property in your codebehind, and in the codebehind, have it return the right property from the config. ConfigurationManager.ConnectionStrings("PathLogout") or whatever. Indeed, you could just use RegisterClientScriptBlock to create the variable entirely in your code behind.

I want to apply english spell check for multiline textbox in asp.net 1.0
How can I do this???? can any one send me code
Thanks!!!!!

The most obvious way I can think of, is to control Word on your server, have it do a spell check, and send the results back down to the client.

Tihs is the ASP.NET forum. ASP.NET is a specific .NET technology. I recommend you buy a book, do a google, and generally show some level of intelligence and ability to do basic research. If you can't do that, then, to be honest, you're not going to benefit from anything anyone may choose to tell you.

Resource File: Resource.resx
Web Config File: Web.Config
Dear Friends,
I have created one project in which i can access data from database most of the time for that i added a connection string through web config file but here is my  confusion start i found that i can access the data of "Resource file" from anywhere using Global keyword
for example:
I have created ConnectionString in resource file as shown below
Name: ConnectionString
Value: Data Source=SERVER;Initial Catalog=ABC;User ID=sa;Password=***
Comment: Use for Database Connection.
now i can access this from anywhere in my application using follwing syntex
global::Resources.Resource.ConnectionString.ToString();
can anyone explain me why there is web config file and resource file having same functionality but different name i know that there is some reason i want that reason thanks in advanced![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Resource files, from what I understand, are ment to be used for localization. Web.config is more for local independent settings.
