You read that where? When you are working off articles or examples and have a question relating to that work, post a link to it along with your question, so we can see what you are attempting to understand.

i don't find that relevant . I would google it right now , but a snail would be much faster than my internet connection right now . There are forums and hints saying that the dynamically created controls should me initialized in the Page_OnInit . If that's right , give me an example please, if not , just tell me what to do Smile | :)

Here's a tip for using internet programmer forums to ask for help on subjects you don't understand. Since you don't understand the subject, you are not qualified to judge what information is relevant.

No, it was "crack" not "crap".

That's not my fault, look in the mirror, there's the person that didn't even save a bookmark to the article they used to develop software from.

That is a good article you are using (http://aspnet.4guysfromrolla.com/articles/092904-1.aspx). Most likely you troubles are caused by incorrect implementation of ViewState. Did you understand the article and the other articles it linked to about ViewState? It would be critical to using dynamic controls for post-back operations.

If you have a limited number of situations and combinations of controls, I'd consider creating them on the server, setting them as hidden using css and then showing them instead of creating them. Or I'd create a hidden field on the server, and put XML or some other string in that to tell you what text had been entered.

Hi,
I am trying to do the below

In Server Side Page_Load (IsPostback) with sever side conditions I am Calling javascript confirm and trying to Return Client Confirm Return value back to the Server on the Runtime. I have pasted the both Server side code and Javascript function below.

ClientSide Javascript:

function UnSavedDataconfirm(Hdn)
{
var hdnfld = document.getElementById(Hdn);

if (confirm("There are some unsaved data. Are sure you want to Change Project Selection?")==true)
{
hdnfld.value = "True"
}
else
{
hdnfld.value = "False"
}

}

ServerSide Page_Load:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Page.IsPostBack = True Then

If IsValidProjectSelection = True Then

Page.ClientScript.RegisterStartupScript(Page.GetType, "UpAlert", "<script>javascript:UnSavedDataconfirm('" & hdn_pschange.ClientID & "');</script>")

If hdn_pschange.Value = "False" Then '(No value Returned from client)
Exit Sub
End If

End If

End If

End Sub

Please let me where I am going wrong or let me know know if there is some other ways to handle this situation.

Thanks in advance.

what is the issue ? Where do you find it doesn't do what you expect ?

Why do a postback if they don't want to save ? Use OnClientClick to return false if they don't want to save and the OnClick of a button will not be called, no postback will occur.

Isn't he expecting his server variable (hdn_pschange.Value) to have changed after he adds his javascript to the output stream? Surly that's not going to happen right?

Isn't that what UnSavedDataconfirm does ? Set the text in that hidden control ? Either way, his problem is so urgent that he can't answer us, so....

Sure but it's not going to effect the current state of your server code at the time you call Page.ClientScript.RegisterStartupScript

Re: Help with creating a link using a drop down list in a form

10-Dec-08 7:37

Thanks for your help in advance.

Here is my problem. I have an asp page that is a calender.
Once someone picks a Lake and then moves forward 1 month or back one month (using th e < or > images in the calendar on the right side of the screen) they lose the lake and need to repick it. Somehow I need the links associated with the images < and > to dynamically create the URL using the LAKE selected.

I have full source code for anyone who wants to take a look at it.

Here is the page.
http://www.basscalendar.net/

Thanks again and I am even willing to pay someone a few bucks to make it work (paypal) if you think you can do it. It's been giving me fits - but, I am database programmer not a web programmer!

Re: Help with creating a link using a drop down list in a form

I suspect that you've got selection of some sort happening on the page, but it's lost when your calendar does a postback. Please explain how a lake is displayed and how it's selected. DO you mean a lake, as in a picture of water ?

Re: Help with creating a link using a drop down list in a form

Yes a Lake is a Lake as in Body of water or "Event Type" that will limit the results shown in the query to that lake only.

explanation on what the page does: It is a calendar of fishing tournaments. The tournaments happen on many lakes and we would like the user to be able to show just one lake's events and then be able to advance month by month looking at all the tournaments only on that lake. . It does work to show the current month only for the selected lake but, when you click < or > to get to the next month - it loses it's lake setting and you have to start over by choosing that lake again.

Would you like me to email you the .asp page?

As I mentioned I am willing to pay for this small modification.

Thanks for your help.

Re: Help with creating a link using a drop down list in a form

10-Dec-08 9:35

No need to pay me, helping folks is what we do here.

How is the list of lakes shown ? Where does the list come from ? One common mistake is, if you have a control that is databound and your code sets the data source and databinds every time the page loads, then any selection will be lost. You should set the datasource in a block like this

if (!IsPostback)
{
// set the datasource and databind.
}

If that's not the issue, then perhaps post some of the aspx, so we can see how the calendar and list of lakes are created.

TomLeogrande10-Dec-08 9:42

Re: Help with creating a link using a drop down list in a form

10-Dec-08 9:42

It is databound.

Looks like this

;
All Lakes
<% IF ISARRAY(aryreg2) THEN%>
<% for j=0 to ubound(aryreg2,2)%>
]]>
<%next%>
<%END IF%>

I think I understand what you are saying about the dynamic building of the select page.
Hmmmmm Sounds like it may not be possible with the databound select list.

Christian Graus10-Dec-08 9:47

Re: Help with creating a link using a drop down list in a form

10-Dec-08 9:47

Is this ASP.NET, or ASP ? It looks like ASP to me. You are indeed building a list, and doing it the hard way, if this is ASP.NET, which I doubt. You're going to lose your selections, because you're rebuilding your list.

Re: Help with creating a link using a drop down list in a form

OK. I would heartily recommend you abandon ASP if you can. You can get free dev tools for ASP.NET and it's a whole different world. It's actually nice to work with. I'm sorry, I hated ASP when forced to use it and I've not used it since it became obsolete, in 2002. I would recommend you try the web development forum, that's where ASP questions belong. Even then, there's not many people who still use it. Broadly speaking, you need some way of setting which objects are selected as you write them into the list ( that part is easy, it's knowing which parts are selected that is hard ). I suspect you'd write javascript to store the ids of selected lakes into a hidden field and then you'd pull that value out of the post data when the form reloads. I do recall having to do that with ASP.

Sorry I can't help more. Why are you stuck with ASP ? Is it a legacy project ?
