Can you look at the event log ? Is there any error related to W3C service or IIS?
|
|
|
|
|
Also did you enable Windows Authentication for the website?
|
|
|
|
|
Windows Authentication was enabled on the IIS.
This has not solve the problem.
Can i develop my asp.net pages using the File System instead of IIS when done, now create a virtul directory from IIS. I dont know whether this approach has any drawbacks
pls anyone with a solution should help

I have a custom server control that behave like an image button and a image map. I implement both IPostBackDataHandler and IPostBackEventHandler interface. I place Page.ClientScript.GetPostBackEventReference(MycontrolID, "") on the page's Page_Init() subroutine. I also code all the javascript function. On my test page, I have my custom control and a button. When I click my custom control, my RaisePostBackEvent gets call properly and I got the correct argument passed in from postback. However, when I put my custom control on the content page along with 10 other button and image button, my RaisePostBackEvent no longer get call. Even though my viewstate and control state continues to get process properly. I do not understand why. Can anyone help me ? I have been stuck on this for a week.

Will there always be a hyperlink and it is just a matter of what the link points to? If that is the case you just need to do some custom binding using a Templatefield with a hyperlink control. You can bind the hyperlink properties to the correct values from your data table. Anyway hope that helps.

Hallo,
i want to close my PopUP Page, in codebehind???
Please help me...
|
|
|
|
|
That is not possible, as the server code is run on the server, and window that you want to close only exists in the browser.
What you have to do is to put Javascript code on the page that you are creating, that will close the window.
Example:
Page.ClientScript.RegisterStartupScript(this.getType(), "Close", "window.close();", true);

Hi,
I have a page with a Panel control with its Visible property set to false in the markup. I've then got a button event handler that sets this to true. When the page renders this has somehow found its way back to false. Using some logging and debugging I've determined that the event is definately working as expected, but by the time the OnPreRender event fires the property has changed back.
Can anyone explain this?
protected override void OnPreRender(EventArgs e)
{
log.Debug("PreRender, visible: " + AccessInfoContentPanel.Visible);
base.OnPreRender(e);
}
private void ToggleContent()
{
if (AccessInfoContentPanel.Visible == false)
{
log.Debug("content made visible: ");
AccessInfoContentPanel.Visible = true;
AccessInfoContentPanel.Enabled = true;
}
else
{
log.Debug("content removed: ");
AccessInfoContentPanel.Visible = false;
AccessInfoContentPanel.Enabled = false;
}
}
protected void ToggleBtn_ServerClick(object sender, EventArgs e)
{
ToggleContent();
}
Cheers!

My guess is that the initial setting the panel to visible = false might be happening in the page load as well? Or perhaps you have viewstate turned off? That is where I have usually found these bugs. I have done some very similar things in ASP.net.
NOTE a better way to do what you are trying to do might be to use a PlaceHolder control instead.
Anyway, hope that helps.
Ben

I've experienced an issue in the past where changes in the browser do not make it to the server code when a control is disabled.
Test the same code with AccessInfoContentPanel always enabled. You may want to enable before changing visible to true.

I have the page break problem in my report. In the report first I placed a table with contains 50 rows(data will be shown in two pages) and after the table I placed the matrix object becuase the number of cols is not fixex. The problem is that if the number of columns in the matrix is greater than 10 then it prints the remaining columns in the next page but at the same I am getting the page breaks in the first table i.e between 1St and 2nd page I am getting page break.
How can I delete the page breaks.

Hello guys,
I have a lot of documents in filesystem of a web server (1). An other web server (2) should offer access to this documents too. That works fine and my generated links to the documents will load the document inside the browser.
My problem is, the documents (the name, not the data !!!) and the path are administer in a database and I have a test, if the document exist, before I provide the link. The code for test is follows:
fi = New FileInfo(strPhysPath)
If fi.Exists = False Then
' do an error message here
else
' generate a link
end if
For this check I need a physical path and I have it in different ways. As "normal path" (i.e. "x:\documents\pdf\test.pdf"), if the code runs on web server1 (the server, where the documents are stored), as UNC-Path to a shared folder (i.e. "\\server1\documents\pdf\test.pdf") and/or as a network drive path using the shared folder (i.e. "y:\pdf\test.pdf" where y: -> \\server1\documents). The last both variants I must use on web server2 and here I get always: File not exist using the code above. No errors, no execptions.
Why? Did anybody have other ideas ?
Thank you very much
Stephan

Well, If you are using a normal default app pool for this website most likely you are trying to access these files with the aspnet user. My guess would be that this user does not have file permissions to read the directory. NOTE if you do give aspnet user read permissions to the directory it can be a security issue.
The only other thing I can think of is using the System.IO.File.Exists instead of using the FileInfo class.
Hope that helps.

Hello Ben,
An application pool is it not and this is not possible.
Your second idea works, but I have also a test for the filelength (System.IO.FileInfo.Length). Did you have an idea to change this part too?
Thanks

Since you are using VB.net you can try:
Dim MySize As Long
' Returns file length (bytes).
MySize = FileLen("TESTFILE")
Otherwise you are stuck with the FileInfo Class

i have this scene
i have load x page.aspx this page call a function javascript this function call a web service it receives a string
next
in my page have a hidden field it is a hidden texbox and the javascritp function pass the value to a hidden texbox
example
client side
window.Form1.lblRid.value = cadena[0];
when the user postback i use the hidden field to x actions
example
server side
If lblRid.Text <> "" Then
this technique is very bad could that to create an hidden field for each occasion
thanks for the time
|
|
|
|
|
I would suggest instead using a hidden field like this:
In the javascript you can do this:
document.getElementById("content").value =
This in your .net code behind you can do this:
Request.Form["content"].ToString();
Hope that helps.
Ben
|
|
|
|

ya. i think, using hidden field is an idea..
Maybe, you can also read "Accessing the Client-side variable (variable named “str” in this sample ) from Server-side Code" from article.

i have limited the max length of the text box through javascripting .When the users wants to add more text the label on the page should read a message like maximum text has exceeded ...
The problem is through javascripting i am not getting the label control.

One more suggestion..
sometimes, Server control name and the name of the control at runtim might be different. Eg: You named the lable as "label1". but this label name might be something else (eg: ctl_label1) after rendering HTML.. so, better to make sure the id that you want include in your page.
Thanks and Regards,
