in your ascx page you have to define an ID for your dropdownlist, in this example it is "MyDropDownList".
the grid has ID MyGrid

foreach(DataGridItem dgi in MyGrid.Items)
{
DropDownList myDropDownList = (DropDownList)dgi.FindControl("MyDropDownList");
string strSelectedValue = myDropDownList.SelectedValue;
}

not shore what you meen, but I don't think cookies gona help you with this.

You have to call your update method, something like

<br />
public void updateMySQL_table(int rowID, string valueFromDropDownList)<br />
{<br />
string sql = null;<br />
DataManager dm = null;<br />
<br />
try<br />
{		<br />
	sql = "UPDATE someTable SET strTheColumn = 'valueFromDropDownList' WHERE someRowID = " + rowID.ToString+ ";";<br />
				 <br />
<br />
	dm = new DataManager();<br />
	dm.ExecuteSQL(sql);<br />
				<br />
}<br />
catch(Exception e)<br />
{<br />
	throw new Exception("updateMySQL_table failed. " + e.Message);<br />
}<br />
finally<br />
{<br />
	if (dm != null)dm.Dispose();<br />
	dm = null;<br />
}<br />
}<br />

each row in your Grid should also contain a value where you have set the rowID, something like

<br />
<asp:TemplateColumn><br />
<ItemTemplate><br />
	<input type="hidden" runat="server" id="inRowID" value='<%#DataBinder.Eval(Container.DataItem, "rowID").ToString()%>'><br />
</ItemTemplate><br />
</asp:TemplateColumn><br />

This you also have to retrive the rowID

<br />
HtmlInputHidden _inRowID = new HtmlInputHidden();<br />
DropDownList myDropDownList = null<br />
foreach(DataGridItem dgi in MyGrid.Items)<br />
{<br />
_inRowID = (HtmlInputHidden)dgi.FindControl("inRowID");<br />
myDropDownList = (DropDownList)dgi.FindControl("MyDropDownList");<br />
updateMySQL_table(int.Parse(_inRowID.Value), myDropDownList.SelectedValue);<br />
} <br />

Hope it helps
Thomas

Do you know in visual studio you can use some authomatic possability.I mean exacly if you made some sqldatasorce and then go to property of this sqldatasorce you can go to query.When you are there you can type directly update function and to add some parameters so my problem is going from that becaus i can't give one paramet who i can take only form dropdownlist.Do you know how to do that ???

Sorry I'm not familiare with that, but you can't update a tablecell with only one parameter, you need to know witch row the the cell is in, thus the rowID (the unike ID that belongs to that table), it is usaly the Primary key for that SQL table.

I have build my web in asp.ne and c#. I want to put certain user permissions as they login. the website contains several pages and on each page different users have different access level. like admin can do all operations whereas a simple user only can view or add but not delete. I want also the administrator to change the user access level from time to time.

You're probably going to have to override the drawing of the TreeNodes and draw them manually. You can draw them wrapped using the StringFormat class. You'll also want to turn off the horizontal scrollbar for the treeview.

Search string for ascii carriage return and replace it with a br???

I need to search a plain text string find the ascii carriage returns (or whatever SQL Server returns them as) and replace them with some < br > tags.

I cannot find (using Google) an example for how to do this.

Ideas?

Thanks,

Actually

you tell me if you can spot the problem...

First Attempt: (FAIL)
tmpStr.Replace("\r\n", "<br>");

Second Attempt: (PASS)
tmpStr = tmpStr.Replace("\r\n", "<br>");

If I would have taken the time to look at the code in the debugger I would have seen that no net change occurred but there was in fact a pile of "\r\n" strings in the text. D'Oh! | :doh:

Yeah, that's one thing I wish I could turn the clock back and have the CLR team change: the string.DoSomething functions don't actually modify the string as they would have you believe. They should've renamed them to make it more clear what's really happening. Better yet, make them static methods.

Nothing modifies strings, they are immutable.

Yeah I know, that's what I'm saying: the current string methods as they are lead one to believe they modify strings, when in reality they create copies of the original. The names should've been named something to reflect this fact (ReplaceInCopy or something), or have the string methods be static methods rather than instance methods.

Building Regex in C#

Hi
I'm trying to build a quick app in C# to filter out some info from emails, like the user's email address and why the email didn't reach the user.
example :
The text I'm using is the following:

"Hi. This is the qmail-send program at store3.netvisao.pt.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

username@domain.com:

Sorry, no mailbox here by that name. (#5.1.1)"

I would like to build a regex based on this text.

Can anyone give me a hand on this?

Thanks in advance.

Jorge

In this particular case I'm interested in extracting the email address and the specific reason why the message wasn't sent.

Thanks for the reply.

I tried the Invalidated event and its only fired for the first time. After the TreeListView is displayed once and then user clicks/checks one of its node, ItemCheck event is fired. I want to know the next event fired after ItemCheck that actually set the TreeListView with all the checked and expanded Items before dispayng.

Thanks.

HttpWebRequest Problem

Hello. I am using HttpWebRequest to post some photos to a website. For some reason, I can post two photos to the website, then every other one times out. So, I restart the program, it does the next two, then times out on the rest. I am using .net 2.0, and here is my sample code:

<br />
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(string.Format("{0}/{1}", this.sUploadURL, this.sAuthHash));<br />
                        req.Method = "PUT";<br />
                        req.AllowWriteStreamBuffering = true;<br />
                        req.KeepAlive = false;<br />
<br />
                        Stream reqStream = reqStream = req.GetRequestStream();<br />
                        FileStream reader = new FileStream(fullFileName, FileMode.Open);<br />

It times out when I call req.GetRequestStream(). Any ideas?

Double buffering is not working

Hello all i am noob to C#(though i have a lot of former experience with c/c++)
anyway i am new to graphical oriented aplications)

I created a form .
the doublebuffering field is set to true.

Now i am animating a square on the screen using the timer controler
and the system.drawing.graphics functions.

I still see flickering effects though i turned on the doublebuffering, i know that the doublebuffering option should eliminate the flickering things but it doesnt.

anyone got any idea why it happen?

I am using VS2005

We'd really have to see some code. Also, if you're doing the painting for the control itself, make a call to the following inside you're constructor:

this.SetStyle(ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint, true);

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
