Hello,
This is my first time submitting a question ANYWHERE, please be kind to the noobie.
Situation:
• Creating a NOTING System for indivisual users
• Notes are stored in DB and retrieved for display on the web application
• Notes are grouped by Date entered
• Since notes can be lengthy an abbreviated notes is displayed
• A hover control is created to "show" the full note for reference/editing and deletion
• Nested Parent to Child controls are as follows
> PlaceHolder [ph_your_note] (static created on aspx presentation layer)
--- ALL dynamic cotrols are placed here ---
> pnl_main (created to house nested controls in one panel
> pnl_date (created to hold all notes of one date value)
> hvm_note ( hover control to show the sub panel that displays the full note)
> pnl_sub (created to hold the note header, textbox, update and delete image buttons )
> tb (text box that will be used to Display/Edit returned value of the
full note written to the database)
THIS IS THE CONTROL I AM LOOKING TO RETRIEVE THE VALUE FROM
What I currently know:
• The dynamically created Update Image Button is where I am trying to retrieve the tb.Text value (shown in code snippet below)
• I have located the value of the text box here, through QuickWatch
((System.Web.UI.WebControls.TextBox)(((System.Web.UI.WebControls.PlaceHolder)pnl_your_note.Controls._controls[0]).Controls[23].Controls[1].Controls[0].Controls[1])).Text
>Controls[23] is the varible that I need to determine how to dynamically call

so, ctrl_name can't EVER equal string.empty. Do you mean if notes_id.ToString is an empty string ? Where does notes_id come from ? Could it be null ?
Wait, this is not a web question. I would create a map that maps the notes_id itself to the control, so you can just look up the control, using the info you have at hand.
ARGH !! It IS a web question. I am confused. Yes, use FindControl to find the control.

• You are right about the ctrl_name, that was an attempt in the wrong direction.
• notes_id is never null, it is the UID from the database pertaining to that particular note
• I have tried the FindControl, but I am very UNclear on how to find that control 5 controls deep.
•• I have also made unique Ids for each control with the control name appended by the note_id
ex: pnl_sub_53
tb_53
hvm_note_53
(53 = note_id)
not sure why this is not a web question, and to your comment on mapping the note_id to the control, I assume that is what I am doing on the ID section (above ••).
one thing that I have noticed that the control elements are not visible to the img_btn_update_note_Click event How can I make them accessible to any or all CLICK events?

If FindControl does not work, perhaps you need to find the control at each level as you work your way down ?
Steve Crochet wrote: not sure why this is not a web question
I just read your C# part and suddenly thought I was in the C# forum. My bad, sorry.
Steve Crochet wrote: and to your comment on mapping the note_id to the control,
I meant building a map in memory, but that won't work, because you don't have any state.

How do you mean, not visible ? What elements are we talking about ?
Ultimately, you can iterate through the controls collection looking for controls if you know where they are.
I just looked at your code again. You call BindNotes ( which adds the control ) AFTER the code that's supposed to work with the control. If you're having to add the controls again in the same method, why not just pass the id you're looking for into that method and deal with it as you add it ?

Hi,
We are building an ASP.NET page and in that we need place a Scrollable Panel containing a ListView.
The ListView in-turn will hold different records, which are retrieved from Database.
Could anyone please refer a code sample for this?
Thanks and Regards.

|

Place the ListView in a div and apply the CSS property overflow:scroll to it.
only two letters away from being an asset

string str1 = DropDownList6.SelectedItem.Value.ToString();
string str2 = DropDownList7.SelectedItem.Value.ToString();
string final = str1 + "-" + str + "-" + str2;

Try This .
DateTime MyDateTime;
MyDateTime = new DateTime();
MyDateTime = DateTime.ParseExact(final , "yyyy-MM-dd",
null);
cmd.Parameters.Add("@startdate",MyDateTime );

im able to insert it..
i want to retrieve startdate column and transfer to other page using session..
using datareader i stored that column in a string
SqlDataReader dr = cmd.ExecuteReader();
while (dr.Read())
{ Session["startdate"] = dr["startdate"];
}
in next page to tranfer the value
if i write this
DropDownList1.SelectedItem.Text= Session["startdate"].ToString();
im getting complete date(10/20/2001) in DropDownList1..
but what i want is ddl1(10) ddl2(20) ddl3(2001) as i inserted...

Which is exactly what you coded. If you want to separate the values across different drop downs then you need to separate the components of the date. Day to one, month to another, and year to the third. How complicated can this be?
|
|
|
|
|
You need to split them before store.

One sample code for you.
String DateText="12/10/2009";
String [] DatePart= DateText.Split('/');
string dd=DatePart[0].ToString();
string mm=DatePart[1].ToString();
string yy=DatePart[2].ToString();
Hope you can take it forward. Let me know if any more issue.

I would prefer this one as it does not believe on string manipulatio and when we have datetime datatype then why do string manipulation?
String strDate = "12/27/2009";
String strFormat = "mm/dd/yyyy";
System.Globalization.CultureInfo provider = System.Globalization.CultureInfo.InvariantCulture;
DateTime dt = DateTime.ParseExact(strDate, strFormat, provider);
String dd = dt.Day.ToString();
String mm = dt.Month.ToString();
String yyyy = dt.Year.ToString();
|

|

Yes Nish, You are Correct. Actually there are many ways that we can implement it. I have given a very basic example. You given much better!
Thanks !

If everybody stored their datetime values properly as DateTime values and not as strings they would not get into this mess. Who is teaching all these awful habits?
|
|
|
|

Session["headline"] = dr["headline"];
Session["startdate"] = dr["startdate"];
Response.Redirect("newsedit.aspx");
next page
TextBox5.Text = Session["headline"].ToString();
String DateText = Session["startdate"].ToString();
String[] DatePart = DateText.Split('/');
string dd = DatePart[0].ToString();
string mm = DatePart[1].ToString();
string yy = DatePart[2].ToString();
DropDownList6.SelectedItem.Text=dd.ToString();
Object reference not set to an instance of an object.

What is ur question ?

I guess this one.
What is the value of dd.ToString(); ? Does this exist on the dropdownlist? Hope now you understand what I want to mean

Hi,
I need to display the content in my site of a particular link using RSS.
Eg:
When a user click the link of a new which is displayed using RSS, i need to display the content also in my page, without going to another site or source site. For yahoo RSS we get all links, When we click a link it will redirect to yahoo site for the content.
How can i bring the content in to my site without going to yahoo? How it possible? Is it possible?
Thankyou
