Cool. Thank you so much

After I View the source code during the runtime, I find the ID of the textbox.

The ID of the textbox is "ctl00$ContentPlaceHolder1$TextBox1" The name of the textbox is just TextBox1 and the "ct100" I don't know what it means but it's just there.

Just in case someone has the same problem with me.

Cheers,

The ctl00 is the ID of the master page instance at runtime, you can set the Trace="true" in the Page directive, browse the web page and look at the control tree section that may give you some information.

hello all,

i have the following problem:
in a page i render the html output of a calendar control manually by cal.render(writer)
in first second it look ok but unfortunately there is no functionality rendered to the output. That means no links, no script code, ...
Is there a trick to render the needed java script code to the resulting HTML?

thanks, bernd

hmm, you may think this does not make sense, but i try to create some aspx stuff by ironPython and so i haven't not a real aspx enviroment. That means i haven't a page_load event or something like that. Does someone of you know some details about the rendering process of webcontrolls in common? For example which method renders script code, who call's this method and when is it called?

i'll be happy about any suggestion. Thanks

Bernd

Hi there,
You may want to look at the Page Object Model[^] and Page Life Cycle[^] that may give you some ideas. Basically, the common script which can be reused in the web page will be emitted by the Page instance, and the control-specific script can be rendered by the control itself. Which script are you talking about?

hey minhpc_bk, nice to read you!

i.E the function '__doPostBack' and all call's to that function are missing. actualy no links aren't rendered. you can take a look at www.gmc.li. First i'll check out your posted link's.

thanks, bernd

stop - the function will be rendered!! In my control isn't set the Property 'Page' which can explain a lot Wink | ;)

-- modified at 16:51 Monday 2nd October, 2006

false alarm Frown | :(

the script was rendered by another aspx control. still with no idea. isn't there a property 'enableClientScripting' ore something else? Please take a look at the code[^] here, maybe one of you can see my big mistake.

To work around the error of not being placed outside the server form element, you'll have two options here:

+ Extend the Page class, override the VerifyRenderingInServerForm method and leave it empty.
+ Extend the Calendar control and override the Render method to skip the calling to the VerifyRenderingInServerForm of the Page instance.

Below is the sample code for the first option which IMO is much simpler:

public class ExPage : Page 
{
    public override void VerifyRenderingInServerForm(Control control)
    {
        //Leave the method empty instead of 
        //making sure the control is not placed outside the server form.
    }
}

It seems that all the links for the Web Application Project of VS 2005 are broken in Microsoft for this topic like the one bellow.

You can download WAP and its prerequisites for Visual Studio 2005 from http://msdn.microsoft.com/asp.net/reference/infrastructure/wap/default.aspx.[^]

However this one works.
http://msdn2.microsoft.com/en-us/asp.net/aa336618.aspx[^]

The above link is missing the aspx extension!!!!

I want to show a piping diagram on the webpage with the movement of fluid in it. The piping should stay as such with only the fluid movement getting refreshed every 30 secs. Is it possible to have a fixed image and a moving point superimposed on the webpage ? Only the moving point should be loaded everytime ?

Adjust to disable "Debugging Not Enabled" messagebox?

I'm using V.Studio 2005 to program ASP.NET 2.0 pages.

For every first debug run of my app, a dialog box
titled "Debugging Not Enabled" will show. It always
has two options:
1. Modify the Web.config file to enable debugging
2. Run without debugging. (Equivalent to Ctrl+F5)

I always have to select one of the option to continue
with. Is there any setting I can adjust to eliminate
this message box for all subsequent new ASP.NET pages?

Thanks for your reply...

Pedestrian, Penang.

First you may have to read this:
from msdn.

However VS automatically adds the debug=false to the compilation property in the web site project's web.config file.
Hence you may have to change the VS template - to assign the value "true".
Recall that you should set debug=false before deploying in order to remove all debugging information.

VS template reference could be found in:

Visual Studio Template Reference

and you can find more articles on the web.

Finally, there may be a very simple way to acomplish this - nothing that I know about.

Best regards,
elaj

You use the ImageField when you have the url of the image and specify it in the field. This question is common and asked many times already, so you can search for articles, sample code posted here using the search functionality or Google[^]

Hi All

I am building an small page in asp.net by using vb.net. The page is having 10 different controls from which one is UserName. I have two button one is Submit and other one is check user availability. Check user avaibality will be use by user to see if entered user name is available or not.

Now I am doing below tasks

1)On page load - Adding Javascript function
Me.CmdCheckAvl.Attributes.Add("onClick", "return bValidateUserName(" & icount & ");")

2)Public Sub CmdCheckAvl_ServerClick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CmdCheckAvl.Click

'To Check user name already exists in db or not. This will be check by using Session("UserNameList") which is build from serNameVw

Dim UserNameVw As New DataView
UserNameVw = Session("UserNameList")
UserNameVw.RowFilter = "UserName=" & "'" & Me.TxtUserName.Text & "'"
hdnCount.Value = UserNameVw.Count
icount = hdnCount.Value
End Sub

But by this icount in step one is always zero….

how i can pass server end value to client site code or any other workaround by which i can acheive the functionality..... Roll eyes | :rolleyes:

You assign the value to the icount variable after you use it. That's why it's always zero.

I can't use a Local Resource value

Hello,

I have a page class and inside it I have a ITemplate class to create
the item template of a repeater:

Partial Class Contacts
Inherits System.Web.UI.Page

Private Class myTemplate
Implements ITemplate
...
Private Sub()
MyLabel.Text =
Me.GetLocalResourceObject("MyLabel.Text").ToString() *****
End Sub
...
End Class

End Class

My problem is that in line ***** I get an error when trying to access a
local resource:

"GetLocalResourceObject is not a member of Page.myTemplate"

So basically I can use my local resources in my page class but not in a
class inside it.

How can I solve this problem?

Thanks,

Miguel

Use the SubString method to get the separate parts of the string and the ToUpper method to turn the first part to upper case.

Hi there,
You can see many examples from the stater kits[^].

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