Well, it seems you're in way over your head.

1 - you set a breakpoint with F5, then the program stops at that point and you can step through to see what happens
2 - as you don't know what a delegate is, I assume you copied and pasted this code, which by itself, can never work. A delegate is a function pointer. Your code tries to call a delegate to do the actual search., and if you didn't hook one up, no search will occur.

All of this code is far too much - all you need is SQL to do the search and take the search term, and then to call that SQL to get the result to bind to your grid.

So a stored proc that takes a parameter and that's the search term, then use that if you have a search term or if you do a LIKE search, then it will work even if the string is empty.

Definately not using ASP.NET. Perhaps using a webservice ?

Retrieve text from a dynamically created textbox

Re: Retrieve text from a dynamically created textbox

10-Dec-08 10:12

Hey guys..
I have a dropdownlist and , depending on the selected item , i want to dynamically add some textboxes and labels.
The labels are not a problem , but i can't retrieve the text from the textboxes . I read that they should be initialized
in Page_OnInit , but it does not work (or i'm wrinting the wrong code) .
Can you please tell me what to do , and if it's about the Page_OnInit , can you just show me a piece of code using it ?
Thank you !

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.

Re: Retrieve text from a dynamically created textbox

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....
