Hi, thanks for looking
Im having a weird behavior and i dont know whats going on
I have the following code:
Dim panel As New Panel
Dim lbl As New Label
lbl.ID = "Label1"
lbl.Text = "Text"
panel.Controls.Add(lbl)
Dim lbl2 As Label = CType(panel.FindControl("Label1"), Label)
lbl2 is supposed to have lbl but it has Nothing
On the immediate window i get the following info:
?panel.Controls.Count
1
?panel.Controls(0)
{System.Web.UI.WebControls.Label}
System.Web.UI.WebControls.Label: {Text = "Text"}
AppRelativeTemplateSourceDirectory: "~/Test/"
BindingContainer: Nothing
ClientID: "Label1"
Controls: {System.Web.UI.ControlCollection}
EnableTheming: True
EnableViewState: True
ID: "Label1"
NamingContainer: Nothing
Page: Nothing
Parent: {System.Web.UI.WebControls.Panel}
Site: Nothing
SkinID: ""
TemplateControl: Nothing
TemplateSourceDirectory: "/V01/Test"
UniqueID: "Label1"
Visible: True
?panel.FindControl("Label1")
Nothing
How can i get the lbl control??
I cant just use index because i might have many controls inside the panel, i wont always know the order of the controls
Thanks in advance

Did you add the panel to the form control collection?
form1.controls.add(panel);

Thanks for the reply
Adding the panel to the form solves the problem
I hadnt tought about it
If im inside a class, how can i add those panels to the form?
(In httpcontext.current. i dont see anything like page) I can only think of sending page as a parameter, but is that my only option?
If you know any other, please let me know
Im using this functions where i insert and read controls from panels and the normal flow is insert them, and show them on the client, then read the options set on the client and save those to db
In this case, where this is not working is now that im doing this directly (Not sending it to the client), im just inserting the controls, setting values im reading from DB and then reading them (Here is where im getting hte error)(This might seem dumb, but in the function where i read the values, som calculations are done and i would like to reuse thos function the way they are)

I'm trying to use headers property of httpwebrequest to send a cookie to a server. For diong so, ii'm using add method of httpwebrequest.headers.
I can add any header included cookies. But, the problem is the cookie is not recieved by the server.
How i know that is simple. I wrote one page on server that prints request headers and cooikes. when i use my code on this page the cookie is not there (as i said before any other headers will be shown in this page az request headers).
Please somebody help.

I think u misunderstood me. I want to send cookies from client to server. cookiecontainer is an object for response to put cookies in it. without it httpwebresponse can't send cookies back to client.

How do you know that? Did you try it? I did and it works just fine.
HttpWebRequest req = WebRequest.Create("http://localhost/Research/RequestViewer.aspx") as HttpWebRequest;
Cookie cook = new Cookie();
cook.Name = "TestCookie";
cook.Value = "CookieValue";
cook.Domain = "localhost";
req.CookieContainer = new CookieContainer();
req.CookieContainer.Add(cook);
WebResponse res = req.GetResponse();
Stream s = res.GetResponseStream();
StreamReader sr = new StreamReader(s);
while (!sr.EndOfStream)
Console.WriteLine(sr.ReadLine());

I have 2 dropdownlists on a formview. The list of the second one (ddl_2) is depend on the selected value of the first one (ddl_1). I use a client callback function (GetDDL2List) on event OnChange to retrieve the list for the second one. After I selected for a value from the first one list of the second come out correctly. After I make a selection from the second one and submit (post back) the form, however, the selection of the second one is lost.
<asp:DropDownList ID="ddl_1" Runat="server" DataSourceID="ods_1" DataValueField="cde_item" DataTextField="txt_item" OnDataBound="ddl_1_DataBound" onchange="GetDDL2List(this.value, 'ddl'); " />
<asp:ObjectDataSource ID="ods_1" Runat="server" TypeName="Proj1.Test" SelectMethod="GetList1"
</asp:ObjectDataSource>
<asp:DropDownList ID="ddl_2" Runat="server" DataSourceID="ods_2" DataValueField="cde_tem" DataTextField="txt_item" OnDataBound="ddl_2_DataBound" />
<asp:ObjectDataSource ID="ods_2" Runat="server" TypeName="Proj1.Test" SelectMethod="GetList2"
<SelectParameters>
<asp:ControlParameter Name="sGroup" ControlID="ddl_1" DefaultValue="-1" Type="string" />
</SelectParameters>
</asp:ObjectDataSource>

Verify that when you bind your DropDownLists that you are only doing it if !Page.IsPostBack

Thanks for your response. I use two-way databinding and I can not stop the databind.

I have a Search Page which contains dates and text fields. When I leave the Date fields blank an error is thrown in my code stating that cannot "Conversion from String to type Date is not valid".
This happens because I am trying to assign the empty Date Text field to A Variable of type Date. If the Date Text field contains a Date there is no error thrown.
Dim dtDateFrom As Date
Dim dtDateTo As Date
dtDateFrom = tbxDtFrom.Text
dtDateTo = tbxDtTo.Text
Anyone any ideas why this is happening

When the user does not enter a value, retrieving the Text property returns an empty string. You are attempting to perform an implicit conversion of "" to a date, which is not possible. You'll need to guard against this by testing to ensure that there is a value in the textbox before converting, or by using DateTime.TryParse.
Hope that helps.

first check
txt1 means the textbox having Date Value.
if txt1.text="" then
in query pass null keyword for that Date Field.
i.e. here abc is the table with 2 columns frmdt(Date)& name(Text)
insert into abc values(null,'"& txt2.text &"')

you can use array of controls and generate the controls dynamically..
you can even fix minimum number of rows to be generated everytime i.e. 10 in this case.
on SAVE, just calculate the number of elements in array and LOOP through the elements and FIND CONTROL, detect value and fire save query...
OR add the values into a datatable and perform save operation with COMMANDBUILDER
its simple answer

Why not use a grid view. Or a repeater...

try connecting to the database server using some database client (maybe SQLYog etc.) and verify it gets connected to it and you have access to the database.
