Hi Nila,

That works very well...

Is it possible to have the main page open and to create a small pop-up window when the user clicks a certain button. In this small pop-up window he/she should then enter some data and push the OK button which closes the pop-up window and updates the main page ?

Sorry, keep asking questions... but i am discovering the possibilities of ASP.NET ! Roll eyes | :rolleyes:

thank you,

Olivier

Sure you can! I will send you some code samples tomorrow morning... I gotta go to bed now Wink | ;-)

I totally know the feeling; with .Net the discovery does not end!!

At this point, you would have two pages; the main page (with the pop-up button and all) and the pop-up page (where you store your session variables, and have close button).

STEP1:
In your main page, drag and drop either an HTML button or an asp control that doesn't trigger a post back, such as a label. If you want to use the HTML button, make sure you give it a proper ID and runat="server". Once you did that, write the below code within your pageload event:

<br />
yourLabel.Attributes.Add("onclick", "window.showModalDialog('/yourPath/popup.aspx', null, 'status:no; dialogWidth:360px; dialogHeight:229px; help:no; scroll:no; menubar:no; resizable:no')");<br />

---OR---

<br />
yourHTMLbutton.Attributes.Add("onclick", "window.showModalDialog('/yourPath/popup.aspx', null, 'status:no; dialogWidth:360px; dialogHeight:229px; help:no; scroll:no; menubar:no; resizable:no')");<br />

VERY IMPORTANT- make sure you put this code here:

<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
	  if (!Page.IsPostBack)<br />
        {<br />
           //your code goes here<br />
        }<br />
<br />
}<br />

STEP2:
Now, its time for you to write code in your pop-up page. Do all your processing, and then store your result(s) in session object(s):

<br />
Session["yourVariable"] = _someLocalVariable;<br />
Session.Timeout = 10; //in minutes<br />

Then, create a button on your pop-up page, and write the following code for it:

<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
	  if (!Page.IsPostBack)<br />
        {<br />
           closeButton.Attributes.Add("onclick", "window.close();");<br />
        }<br />
<br />
}<br />

STEP3:
The last step is to retrieve the data from pop-up and continue the process in main page:

<br />
_mainPageVariable = (Session["yourVariable"]).ToString(); //if the local variable is a string<br />

Again, make sure you type-cast correctly. If _mainPageVariable is an integer, then your code would be something like this:

<br />
_mainPageVariable = Int32.Parse((Session["yourVariable"]).ToString());<br />

Let me know if you need any help understanding my C# gibbrish Smile | :)

thanx, i just arrived at home....

i'll give it a try tomorrow, this is real fun... didn't know you could do this, it's like a real win application online Blush | :O

just wondering how the main page could "know" when to refresh his page after the user clicked OK in the popup-window? The OK-button just invokes a close-method ?

have a good weekend,

Olivier

How the main page knows?? Simple! The modal window (pop-up that refuses to stay in the background) will have to finish executing, then when it is closed the client gives the control back to the Main Page to finish its execution... much like how most common compilers work now adays.

Just out of curiosity, have you ever gotten involved with Microsoft's artificial intelligence framework?

Nila,

your codes works very well... i now get a nice nonresizable popup-window when i click on my asp imagebutton....

But... my imagebutton only should launch the popup window when a record in my gridview is selected..

i could do this i suppose:

- when user selects record in gridview i set a sessionvariable
- in the pageload of the popup i check wether the sessionvariable is set
if not the popup closes directly
if set it stays open

is that the good way ?

thanx and have a good sunday :->

You can have a MultiView in your pop-up page that displays an alternate View (like an error message) if the session variable for some reason is not set.

If you can afford to do so, stay away from ImageButtons in GridViews! They make your ViewState very big. If I were you, in the GridView I would create a templated field with a hyperlink that would trigger a select event AND upon selection it would store a unique value in a session variable, and that hyperlink would also open the pop up page- just hang in there my newbie! I will get some code examples for you...

How to be a good member of the discussion board

28-Nov-06 3:18

Ok Olivier, this is how you can open your pop-up from a GridView, and pass data bound parameter to the pop-up. In your .aspx source, paste the following templated column:

<asp:TemplateField HeaderText="Click on Url to open new window" SortExpression="COLUMN_1">
<ItemTemplate>
<asp:HyperLink ID="yourHyperLink" runat="server" NavigateUrl='<%# Eval("EVENT_ID", "~/yourPath/yourPopUp.aspx?yourSessionVariable={0}") %>'Target="_blank" Text='<%# Bind("COLUMN_1") %>'></asp:HyperLink>
</ItemTemplate>
<HeaderStyle Width="180px" />
</asp:TemplateField>

Note that yourSessionVariable={0} will send the value of the FIRST column to your target page. Now, in your pop-up you will have to first get Request.QueryString["yourSessionVariable"], do type casting as you see necessary. But, you are now sending data via GET method which is not exactly safe Frown | :-(

You can play around with all the options that you have, and see what works best!

Here are a set of rules to be a good member. Smile | :)

Other members will love you for it:

1. Don't use a descriptive heading to your message/question. Something like "NEED HELP" or "URGENT" should be good enough.

2. Don't ask a specific question. Questions like "How to make a webpage" is fine.

3. Don't try to solve the problem yourself. Many here will do your work for you. Just ask for source code.

4. If/when you get your answer, NEVER say "Thank you" or respond in any way to the person that helped you solve your problem.

Keep these rules in mind, and you will be embraced by this community, and you will become a valued member

Smile | :)

Also, try to reuse popular subjects when possible. It's all been written before, there is no use to do the work again.

Actually, often there is no real reason to ask a question at all, everybody knows already that you want to ask a question. Just paste the code that doesn't work, and people will find out what's wrong with it.

And:

5. use as many abbrev as posbl & dnt waste time on spelln gramar & otr booorin stuf u r here 2 get ansers notn else

6. Use as many smilies as possible to show what you mean. Laugh | :laugh:

How Is Possible Check Row Affected

14-Nov-06 9:08

And my two cents...

when browsing through the posts (mainly to feel better about yourself by seeing how some actually know "less" than you), get super upset at the replies to one's cry for help. In fact, you should stalk them by any means possible, they'll LOVE you for caring that much. Oh, it gets better; you should accuse them of being morons and challange them to a code-off. It sure is a turn on especially to those so called female girl-coders.

Oh and don't forget to use the mean smileys while at it

Change the session timeout in the web.config.

<system.web>
<sessionstate mode="InProc" stateconnectionstring="tcpip=127.0.0.1:42424" sqlconnectionstring="data source=127.0.0.1;Trusted_Connection=yes" cookieless="false" timeout="60">

Specifies the number of minutes a session can be idle before it is abandoned. The default is 20.

Perhaps i not make myself clear.

I code the SqlConnection with Update command manually and update the record. Inot use any DataSet or others. When i run Update it update the informations.

This is good.

But how do i see how many rows records have been updated?

Please your help for i read the dependencies infos but not mean anything to me. This is not right for my problem i think.

Thank
